Wondering why people complain that Yaris' cant get good mileage?!

[jhsouders]

I deliver pizzas for a living. In a pretty heavily stoplight filled area. I on average get 40mpg in town, and have gotten 48.5 on a the highway. Its a great little car! Just drive nicely and it will treat you well.

I tell people what i get and it blows them away. I dont know why. lol

People actually complain about this? Not so much around this neck of the woods. :iono:

[Rain]

Because they drive on 3 :biggrin:

[tk-421]

That would explain some of it. :thumbsup:

[marlondog]

Because they drive on 3 :biggrin:
LOL! I did the same thing when I drove the car for the first time. I was stoked about the way it drove, but pissed that it only fot around 200 miles to the tank. I then figured out that it was not in the right gear, and got it back into drive. Then I noticed the difference: I lost some of the power, but gained twice as much mpg.:biggrin:

[jambo101]

I usually average 40mpg maybe a bit less in the winter,any one getting much less than that either has a mechanical problem or they arent driving correctly..

[STC]

I never really complained, but only inside my head! LOL! After getting only 27 MPG on my first (dealer) fill, I started to read these threads and start applying what I learned. Most of it is all about common sense driving...

Now my average is almost 45 MPG. Only 4.5 months old, I was able to get 504 miles on a tank, close to 50 MPG. I'm not doing so well now, only getting 45 MPG on my last tank. But, later this month and next month I'm taking a couple of road trips... :smile: Hopefully, I can break the 50 MPG barrier... :iono:

Ooops! I never was good? well? in English! LOL! ... :laughabove:

[jhsouders]

I never mentioned it, but my yaris is a 5 speed manual. Not an automatic as it sounds most of you have. And most of my driving in the past has been 100% city. Now im about half and half.

My current tank, i know its not completely factual but, im at 149.8 miles and the second bar hasn't dropped off. If it were to drop right now, id be at about 46mpg. Im hoping to go further before it does. EPA rated it so frickin low

[ddongbap]

I get around 27mpg.

[Palmer812]

I get around 27mpg.

Me too! I only drive 2 miles each way to work and back. My first 2 tanks I babied it. I never accelerated hard or downshifted. I am on my third tank now and have a little harder on it. I will see if it makes a difference. And yes I have it in drive. lol.

[Stove]

I average 28 MPG. I drive about 25 miles to work and back everyday with about 4 miles of that in the city. I leave for work at 5 AM so traffic is not a problem. It probably doesn't help that I drive my Yaris like it's stolen.
:burnrubber:

[jhsouders]

UPDATE ON MY CURRENT TANK! CANT EVEN BELIEVE IT!

ok seriously this is all 50% mixed highway and city driving, and city driving is delivering pizza.

dropped the first bar at 93 miles
dropped the second at 160 miles
just dropped the third at 219 miles

will keep you updated on the rest of the tank, i would be blown away if i was able to hit 50mpg on mixed driving!!

i am sooo close to 50mpg, i cant even believe it
Oh and i drive 55-60 on the highway, with DFCO whenever i have the chance. In town i take accelerations easy, upshift at about 2500 rpm's and try to keep it constant at 40-50mph. hard to do with all the lights though, even though that means more DFCO :).

[BailOut]

Short distances like that will kill your MPG as the engine never fully warms up.

With such a short commute (good planning on your part?) I would bicycle it year round, skipping only the snowiest, slushiest days.

Yeppers! You're close. I was at 237 mi when the third bar dropped off... got 504 miles to that tank when all was done. Unfortunately, it took 10.253 gallons to fill.

Hopefully, soon I will break 50 MPG? :iono:

Good luck with your MPG...

[RETRO]

I've had mine now for 6 months..I am avg 38 mpg.The best I got is 40.5 mpg the lowest is 36 mpg.I drive 82 miles roundtrip to work.All but 20 miles is highway.I am pleased with my Yaris

I having got to 40mpg gallon yet, but i think it has something to do with all the traffic and bs in Virginia.

[Kal-El]

Pretty impressive MPG for pizza delivery. That type of driving is usual infamous for yielding the worst results.

I'm boggled when I hear people say they average below 30 mpg. I think if you drove the Yaris pedal to the metal, stop and go, it would be around 30 mpg.

[CarBob08]

I am amazed to hear that some people are getting 45+. I am averaging 35.5mpg over the life, with a low of 29.6mpg and a high of only 40mpg. Even on really long sections of cruise control at moderate speeds, I generally only get about 38mpg. I do drive the manual transmission, so that will reduce the mileage a bit since the final gear ratio is a bit lower, but I see many posts from other manual owners that claim 45+ too. Time to investigate my car. :confused:

UPDATE!!!



dropped the first bar at 93 miles -- 80% highway -- 20% city -- 46.5mpg -- 70 mph highway
dropped the second at 160 miles -- 80% highway -- 20% city -- 53.6mpg -- 55-60mph highway

all of the mpg readings are of that bar only to give an idea of how each type of driving changed my mpg
i started caring less about the mileage because i was at work, so i was rushed to get things delivered.

more updates to come, ill be sure to post my average over the whole tank.

I wouldn't suspect an issue with your car. That's fairly normal but a imagine you are also driving "normally" which means around 75mph on the highway, and some stop and go without trying hard to get great mileage.

35.5 overall is pretty good. Remember EPA estimates are 29/35 (32mpg average). That said, new EPA estimates are quite low.

Oh, and the manual transmission is rated higher at 36 highway. Regardless of the supposed gear ratio difference, the manual is generally more efficient (maybe because it's lighter).

CarBob:

Your experience with your car on fuel economy is very similar to mine with my car. See my post where I shared my MPG data for the first full year of ownership. I have kept track of every drop of gas that I put in my Yaris from the first time I filled it up after running out the tank of gas the dealer bought.


http://www.yarisworld.com/forums/showthread.php?t=27068

The lowest MPG for any fill-up was 29.49, and that is when the nozzle did not automatically shut off. Between the overfill of the tank and what spilled, the pump was probably showing an extra half gallon or more above what it would have otherwise. I did not allow for the extra gas and just used what the pump showed in my calculations. Whatever amount was overfill would have made the next tank's MPG look better, of course, but what was spilled was just lost. That was the only time that MPG checked out under 30.0. My highest MPG was 43.55 on a long trip. The overall average is 36.72. (The average showing in my sig from Gassavers.org is only for the last 90 days. You can click on that icon and go to my actual data at Gassavers.)

I am not unhappy with the fuel economy of my car, even though it is below what many people are posting. I am not willing to go to extreme hyper-miling techniques like many people are.



Tom

[talnlnky]

speed is huge, and after I got my scangauge and watched the throttle position sensor, I noticed that even driving carefully I was usually wasting gas pointlessly at highway speeds. Once you hit cruising speed, slightly ease up on the gas, reduce the throttle position by one or two points and you usually can maintain the same speed, but your mpg's will go up. Very hard to do without a scanguage tho. Scanguage costs $160ish... but i figure my yearly mpg average is up about 2mpg after I bought mine... so i/m sure it'll pay for itself.... It already paid for itself by diagnosing issues with the fiancee's car.

Its not hard to get good fuel economy and not use crazy hypermiling tricks. to get 50mpg on the highway just go 55-60 mph and DFCO down hills or as much as you can when you need to slow down. Then with the TPS just bring it down a notch and your good. not hard to do at all

Oh and i got my scangauge for 120. nice and cheap on ebay, brand new.

[SilverBack]

My average is about 34 MPG because I'm running 205/50 tires on alloy wheels, and I drive kinda fast and all over the place (but I also keep a very close eye on maintenance and will almost always notice if something's wrong and fix it ASAP). I know I brought this onto myself so I got no room to complain. Some of these drivers really should ask themselves if what they're doing is causing bad gas mileage before they whine about it.

3 and D are in the same transverse slot. When you pull the shifter back from P through R and N, it drops right into D. If you bump it to the left, you're in 3.

That is amazing. I honestly don't know if I can get another 10+mpg by just slowing down to 55-60mph, I usually only go about 70mph on the freeway. I noticed you have the sedan too, it seems like it is a bit more slick through the air than the HB, so that might help too.

The only time I have even hit 40mpg was on a long trip, cruise set at about 60mph, and only one stop for gas in a stretch 550 miles long. My average for normal freeway driving is about 37mpg. As was said in another post, it is just too hard to drive really easy to get the uber-mileage, the car is a lot of fun. When I want to go fast AND get good mpg's, I jump over to the motorcycle (50+mpg and crazy acceleration). :biggrin:

[jhsouders]

I haven't hit 40 MPG yet. Is this all flat roads? I have a lot of hills on my highway commute.

I actually find that i get better mpg on hilly terrain, granted its still highway. Going down the hills i just throw it in neutral getting around 4-5 hundred mpg while maintaining speed (DFCO would slow my car, and i would again have to use gas, so neutral is better in this case).

There is one hill in particular that i drive all the time, 600 ft elevation gain and loss. From the start of my drive, the hill starts, 2.6 miles up, 3.5 miles back down, when i get to the top im at 24-25mpg, once im back at the bottom, im back to 44-45 mpg, then by the time im home, 13 miles later, im about 50-51mpg.

I think my car is magic... :thumbup:

Also, KrazyDawg, i notice you have an automatic, manuals are definitely easier to get better mileage with (which i have), and i baby mine.

Based on your gas log, you fill your tank quite often, what do you do that requires you to drive so many miles? I ask because i deliver pizza's and i do the same.

I have often wondered how so many can get such fantastic mileage yet I still get slightly under 40MPG. Makes me wonder if there aren't some tall tales told here!

poor measurement of gasoline (1/10th gallon) can throw mileage calcs off.

over-inflation of tires is dangerous, yet many high-milers over-inflate
(dangerous in emergency handling and low traction conditions, not really dangerous
dry pavement non-cornering)

also, extreme use of hypermiling techniques (accelerating absurdly slow after stops for example)


I don't do any of the above, and I am getting 43 mpg tank average with 75%
highway miles at 67 mph 2010 Yaris 5 door automatic

this drops to 36 when I start driving around town on short trips.

[Yarisduder]

Are the cars mostly empty too? We're almost always three on board, and I'm sure that lowers our fuel economy.

Stop and go can really hurt your mileage. When I'm doing city driving, I do a lot of compression braking (manual transmission), I time the lights and maintain constant speeds wherever possible. Engine braking with your foot off of the gas shuts off fuel completely so it's even better than idling in neutral! Of course knowing that, you can start off with more of your friction brake earlier to stay in compression braking for longer ;)

When you think about it, if you just reduce the number of times you even need to accelerate, it's even better than accelerating slowly. Very few people drive like that, if you're like the other 90% out there you just follow nose to bumper, mimicking the car in front of you with very little space or time to do anything different.

So knowing that, you should always be paying enough attention to what's going on in front of you to know when you need to start gliding in neutral to slow down, or when you need to start engine braking, always keeping things as smooth as possible for any cars behind you. As a rule of thumb, one should very very rarely need to use friction brakes on the highway. Thinking ahead, paying attention and driving more proactively is the key here, which is actually safer then following bumper to bumper and reacting.

You have to remember that your mileage really starts to drop off after 55, so I like to keep it between 50 and 60, in fact when there's no traffic behind me, I like to make it a point to allow the car to drop to 50 at the crest of a hill, and speed up no faster than 60 at the bottom, making small adjustments to that accelerator pedal where necessary. If there are downhill slopes that allow me to maintain the speed limit at 60 in neutral, I'll do it. And of course I'll use less gas on hills approaching areas where I know I can actually gain speed in neutral. And of course I'll even throw it in 5th gear and use DFCO when I know it will maintain it's speed, essentially using no fuel at all and holding the speed limit.

For me the real limiting factor for my fuel efficiency is that my trips are usually too short to allow the engine warm up enough. Heck, if you're mostly doing short trips like me and you do a lot of city driving you might be right on.

It's really all up to the individual and their driving conditions, but I can tell you from 1st hand experience it's very easy to achieve 50mpg on long trips if you can manage to keep the speed down.

Im only getting 250-300 on a tank. So that's about 22-27mph if im correct. I drove once super slow and hypermillerish, and i think i still achieved only like 310-320 which is still about 29mpg... What do you guys recommend? Im about to change the spark plugs and air filter, any other ideas?

Do you get up to speed slowly from a dead stop? Are you trying to keep your RPM's low by upshifting as much as possible? Cause if you're doing these things, THATS whats killing your fuel mileage.

Fuel consumption is all about load... Load can be visually seen if you use a vacuum gauge. High vacuum is low load, low vacuum is high load, and you'd be surprised to see what little usage of your right foot can do to your vacuum levels.

Think about it this way.... You're on the leg press machine starting with your knees at your chest... What takes more energy? Pushing the weight stack away from you, or holding it there? Holding it, right? the quicker you get there, the less energy you use. It would be like doing a slow leg press to the extended leg position, vs. extending your legs as quickly as possible and holding it there.

Stupid analogy, I know, but hopefully you can see how it works. I'm not saying peel away from every stop light, but do NOT be afraid of RPM's. Shift at 3-4K RPM's, cruise at no less than 2K, and get up to speed more quickly. You don't need to be unsafe about it, but I guarantee you'll see a difference in fuel mileage. Oh, and when coming to a stop, keep your car in gear.... Above 1200RPM's (IIRC) IN GEAR while your foot is off the throttle, your injector solenoids shut off... So you're using ZERO fuel.

/rant lol

PS. Air filters are most efficient at 60% of their life. A clean air filter allows only a slightly better flow, but a much less efficient ''cleaning'' of intake air.

Changing spark plugs won't increase your mileage or power if you're not getting misfiring, which sets the "Check Engine" light and a trouble code. The original plugs are iridium ones good for 100,000 miles. Save your money.

[STC]

Im only getting 250-300 on a tank. So that's about 22-27mph if im correct. I drove once super slow and hypermillerish, and i think i still achieved only like 310-320 which is still about 29mpg... What do you guys recommend? Im about to change the spark plugs and air filter, any other ideas?

What kind of driving in Miami? Mostly highway or city? Miami driving can be very challenging to get high FE.

I used to live in Miami. All the stop and go driving will kill your FE. If you are driving like Kendall Drive (SW 88th Street) from Dadeland to West Kendall, I can see you averaging around 22-27mpg!

The previous poster, "Boost Addicted" gives you good advice!

Too much speeding yo

[TheRealEnth]

haha. ;d i try to keep highway speeds at 60-70 and drive down streets at 50-60

I did change my spark plugs and it sure felt like I had more power. No scientific evidence to support this, but the fool behind the wheel test was successful so that is the only evidence I really care about!

[daf62757]

Stop and go can really hurt your mileage. When I'm doing city driving, I do a lot of compression braking (manual transmission), I time the lights and maintain constant speeds wherever possible. Engine braking with your foot off of the gas shuts off fuel completely so it's even better than idling in neutral! Of course knowing that, you can start off with more of your friction brake earlier to stay in compression braking for longer ;)

When you think about it, if you just reduce the number of times you even need to accelerate, it's even better than accelerating slowly. Very few people drive like that, if you're like the other 90% out there you just follow nose to bumper, mimicking the car in front of you with very little space or time to do anything different.

So knowing that, you should always be paying enough attention to what's going on in front of you to know when you need to start gliding in neutral to slow down, or when you need to start engine braking, always keeping things as smooth as possible for any cars behind you. As a rule of thumb, one should very very rarely need to use friction brakes on the highway. Thinking ahead, paying attention and driving more proactively is the key here, which is actually safer then following bumper to bumper and reacting.

You have to remember that your mileage really starts to drop off after 55, so I like to keep it between 50 and 60, in fact when there's no traffic behind me, I like to make it a point to allow the car to drop to 50 at the crest of a hill, and speed up no faster than 60 at the bottom, making small adjustments to that accelerator pedal where necessary. If there are downhill slopes that allow me to maintain the speed limit at 60 in neutral, I'll do it. And of course I'll use less gas on hills approaching areas where I know I can actually gain speed in neutral. And of course I'll even throw it in 5th gear and use DFCO when I know it will maintain it's speed, essentially using no fuel at all and holding the speed limit.

For me the real limiting factor for my fuel efficiency is that my trips are usually too short to allow the engine warm up enough. Heck, if you're mostly doing short trips like me and you do a lot of city driving you might be right on.

It's really all up to the individual and their driving conditions, but I can tell you from 1st hand experience it's very easy to achieve 50mpg on long trips if you can manage to keep the speed down.


When you have to drive on Interstates, driving slow is dangerous. I drive to Chicago once a week and I am lucky to drive 75 MPH without being run over. At 75MPH, I usually get around 35 to 38 MPG. I wish I could get 50 MPG, but for me, that isn't a realistic goal.

Agreed. Local turnpike (toll road) that I drive daily for approximately 54 miles out of my 100-ish mile commute, the posted limit is 65. I don't dare go much under that for fear of being run over (it's nearly happened a few times).

But even doing 65, I can easily average around 38mpg (occassional 37, or 40).

Not as great as what others can get with their Yarii, but truthfully, it's certainly good enough for me! It's better than most any other car out there performing under similar conditions (ex. prior car was a Mitsu Lancer ES; averaged 27mpg).

[bkrownd]

Some of you peeps need to leave your Road Raging areas and find saner corners of the country to live in.

I really hated it when some of the roads went to 75. Never drove faster than 65 max on those, and never will. As a passenger I was in a car that hit a deer at 75 in heavy traffic, and we escaped death by mere inches. Once was enough...

[bkrownd]

I actually find that i get better mpg on hilly terrain, granted its still highway. Going down the hills i just throw it in neutral getting around 4-5 hundred mpg while maintaining speed (DFCO would slow my car, and i would again have to use gas, so neutral is better in this case).

I've always suspected I get better MPG going up and down shallow mountain slopes than I would cruising at constant speed on flat ground. More energy is wasted turning the motor at cruising RPM than at idling RPM, so storing energy as elevation gain on the uphill climb and coasting or engine braking most of the way back down should yield higher MPG than cruising at high RPM on flat ground. Even despite the extra energy used to climb and the thinner air at higher elevations.

Just make absolutely sure that you're in a car that WILL NOT STALL while coasting. My stickshift Toyotas will idle happily until The End Of Time, but I've encountered some SUV type cars with automatic transmissions that will not idle reliably and are not safe to coast.

The ScanGuage supports your statement exactly. If I keep the speed down under 45 on level ground with little stop and go (country road) I can actually obtain a little over 60 mpg. However accelerating to 70 and no regard for pedal control mileage drops to 32 to 35 and with an opposing wind 28 mpg. The a/c drops it another 10 mpg.

You know, the difference between 41 and 38 MPG is not really that much. The creature comfort of cruise control and AC make it well worth the 3 or 4 MPG that these luxuries cost me.

YMMV. I will get out and push for 3 extra MPG. ;)

[gokartride]

AC isn't really a creature comfort here...it's life support!

[Kal-El]

I'd still run my AC even if it dropped FE by 25%.

If the cabin temp is above about 72 degrees, I run the AC.

[Yarisduder]

So what was said above is that if on my two best tanks I hadn't run the AC I'd have gotten about 50mpg? How much energy does it really require to run the AC? 1hp? 2hp? I doubt more than that, so I should probably see a mere 1 to 2% increase in fuel mileage if I turn it off. Thinking back though, my best mileage is with the air conditioner turned on, maybe it's because the fuel atomizes better in hotter weather? Maybe it's because I changed the engine air filter? It certainly has nothing to do with the AC.

Does the Yaris require the full power of it's engine to keep moving? Is it possible that the AC operates on extra power that would otherwise be wasted and therefore only affects your fuel efficiency when accelerating or driving very very fast?

On the freeway, having windows down creates drag which hurts your FE than having the A/C on.

And no, the A/C doesn't run on magical "extra energy." Just about every ounce of wasted energy has been engineered out of modern highly fuel efficient cars.

[Yarisduder]

I never drive with the windows open, and except for the last two tanks of gas because of a road trip all my driving is city driving.

[Yaris Hilton]

Probably around 35 MPH is a break even point between having the windows open and having AC on. Above that I always close the windows and use the AC as needed. Window drag varies a great deal with the wind conditions, of course. Once I've spent the energy to cool off a hot interior with the AC, I'm unlikely to roll the windows back down. Keeping the AC on low recirculating doesn't take a lot of power.

[BailOut]

This is inaccurate. In both testing with our SGII's and as proven in the 3rd season of the Mythbusters television show, windows down is always more efficient than a/c at any speed.

In fact, with the SGII it is nigh impossible to read the drag hit of having the windows down, but turning on the a/c at any speed is an instant large and sustained hit to FE.

I didn't see that episode, but I did a search on found this website.

http://green.autoblog.com/2007/08/29/mythbusters-mistakes-in-ac-vs-windows-down-episode/

According to the website, windows down does hurt mileage. Just on a simple physics level, the air entering the cabin has to have some breaking action on the vehicle as the air has no place to displace. If you had the tail open, it could be a flow through action that might not effect the velocity of the car.

I am no expert on the matter....but I did stay at a Holiday Inn Express last night and will use my AC....because I love cold air and I am rich enough to afford the extra quarter.

There was a big thread on it that was lost in the hack, but as I said the Mythbusters found the same thing, as did the folks on CleanMPG, as did the folks on PriusChat, etc. In other words it has become common knowledge.

As for the test environment, etc., it simply doesn't matter. Windows down in any scenario is far, far more efficient than using a/c in any scenario. It doesn't matter if you're pulling into your driveway or cruising down a highway, rain or shine, winds or no.

Tinting goes a long way for avoiding a/c use. When combined with window vents it lets me keep the 35% front window on the sunny side cracked about 2 inches and have the shaded window fully down, or both windows down when the sun is directly overhead or to the front. Aided by the 6% tint on the rear windows and top of the windshield (the darkest allowed by local laws) it helps keep the interior much cooler than without any of these things. In stifling heat I run the fan (just the fan - no a/c) on the fresh intake setting to aid with circulation.

Despite living in a high desert region the only times I have ever run the a/c is when my wife experiences hormonal issues. None of my other passengers ever ask for it.

Myth statement
Running a car with air conditioning on is more fuel efficient than running with the windows down.

Status
Partly Busted

Notes
Tests were performed under varying conditions (55 miles per hour (89 km/h) versus 45 miles per hour (72 km/h)). Also, the 55 mph test was using a computer to estimate fuel efficiency based on air intake, not actual fuel consumption, and showed A/C was more efficient. The 45 mph test consisted of running the tank until it was empty, and showed open windows were more efficient. This experiment—or one like it—is sometimes cited by the Magliozzi Brothers on Car Talk when presented with this question.


http://en.wikipedia.org/wiki/MythBusters_(2005_season)

Myth statement
Running a car with air conditioning on is more fuel efficient than running with the windows down. (From AC vs. Windows Down)

Status
Partly Re-Busted/Partly Confirmed

Notes
The fundamental flaw in the MythBusters' test was that the point where the drag becomes powerful enough to inhibit a car's performance with windows down was inside their 45–55mph margin at 50mph. Going less than 50mph it is more efficient to leave the windows down, but going greater than 50mph it is more efficient to use the A/C.



The sad thing is I just pull stuff out of my ass most of the time, you write novels on this crap.

[BailOut]

Interesting, yarrr, but that's not what is shown on the Mythbusters episode. My only mistake was calling it from 2003 rather than the revisit in 2005.

What they found in 2003 was so controversial that they revisited it in 2005 and got the totally opposite response. I'm not sure where the 50 MPG "barrier" idea came from as it's not in the episode (which I just watched again via Netflix) or on the Discovery web site. The only thing shown in the episode was that windows down beats a/c period, and this is what (I say again) consumer testing here on YW, CleanMPG and PriusChat have also shown.

If you don't believe me then get a ScanGauge of your own and go nuts. :smile:

[Yaris Hilton]

I can't believe windows down beats AC in EVERY condition, but I'm not about to buy a Scangauge and do a bunch of testing, either.

[Kal-El]

If gas was $10/gal, I'd still crank my AC. There's no way in hell I'm sweating my balls off on purpose. And I hate my windows down.

[STC]

Well, It's been downright HOT here in Central PA... hazy, humid and no breeze! There has been three days of +95 degree temperature and one of those days close to 100 F!

I've been using A/C more than my usual increments. Around 90% of the time!
I thought this would kill my gas mileage, but it didn't. My Yaris actually does great in the HOT weather. I filled up early this morning and to my suprise I got 49.524 MPG (495/9.995). My second best MPG and no trips... country driving mainly!

I'm taking a trip next week... :smile: Bring on the HOT temperatures... just for next week. :tongue:

That's good to know. I always thought 40-45 MPH was the breaking point between having the A/C and window open but I found out I was actually getting higher MPG on one fill-up with the windows open and 90ºF weather.

Does it make a difference if only the driver side window is open? I don't have power windows.

How much of a MPG hit do you take going from A/C level I to level II? What about when you compare no air to air on level II but with A/C off?

I dont have much experience in the matter as i got my scangauge in the summer, so no heat was needed. But i have heard that heat causes little to no hit on FE, because its only excess heat coming from the engine. Again, have not tested this. And i would assume its not true when the engine is just turned on on a cold morning, but only after its been running a while.

There is indeed an FE hit from using the heater as your engine relies on a certain water temperature as a measurement of engine efficiency and will run rich any time it's not meeting it in order to produce more waste heat. However, it is a much smaller hit than a/c usage, and I believe in keeping my joints warm enough to easily control the vehicle in snowy and icy conditions.

no problem here with the mileage , only the oil leak so far . Took the ECO-METER from the 2010 3 door and installed it in the 2008 automatic sedan before going on a 161.5 mile trip . The ECO-METER showed 44.2 overall and the fill of 3.62 gallons of gas ( always off at 1 click of nozzle ) . This resulted a calculation of 44.56 m.p.g.. This is 85 degree weather , 2 people , plenty of hills , average speed of 48 m.p.h. , 35 p.s.i. for tires , and winds of 25+ m.p.h.. Also cleaned the block where the oil leaks before leaving and was pleased to find there was very little oil to the touch after returning home . Just slight sheen on tip of finger from area it seeps .

[firemachine69]

My average MPG in the summer is between 36-42mpg now.


In the car's defense, when I take it out on the highway, I ain't gonna be that asshole running five-clicks' below the speed limit (real-time speed is about 60mph). The road isn't just about me, after all...

[Hershey]

F.M, , I take it your YARIS is getting better mileage now .

[jcemitte]

I usually average 40mpg maybe a bit less in the winter,any one getting much less than that either has a mechanical problem or they arent driving correctly..

i wouldnt say incorrectly, i would say more fun-er :)

i drive my yaris hard and i still get 33-34 mpg how could anyone complain about that?

i wonder what garm gets in his....

[ChilliwackGuy]

Hmmm - in BC, Canada - before you enter most freeways - there is a sign that bans certain vehicles from entering - such as farm tractors - and basically anything that cannot reach a quoted "65 KM/HR" - so I guess 65KM/HR is the minimum speed that you are expected to average if the traffic flow allows it - on a BC freeway in Canada.

The maximum around here is 100KM/HR - and it's standard for people to exceed by 10-20KM/H.

[Wave]

I average between 29.5 and 31.1 mpg. I do push it though, and recently I think that may be coming back to bite me. Might need a new drivetrain at 70,000 miles :(

[salmonz]

I get 7.4L/100km or 32 MPG (US)

[Gr8ful_Ken]

My mileage experience. I'd say 50%/50% town/hwy. Relatively flat terrain. My highway speed tends to be 65-70. I'm not a hard accellerator. I personally dont think hypermiling techniques are worth the money saved. There have been many days with heat index above 100 lately so AC has been crankin'.

First tank 36.1 mpg
Second tank 35.8 mpg

Roof Rack went on towards end of 2nd tank.

3rd tank 34.9 (towards end of third tank, I did drive a bit more aggressively to have fun when break in period was through).

Not near what many folks claim here, but I am quite happy; my previous 4 vehicles got 18mpg (06 Silverado), 17mpg (98 Ranger), 17mpg (06 Frontier) and 15mpg (90 F-150).

[bkrownd]

With all the data on this website available regarding Yaris' 40++ miles per gallon, you would think Toyota would petition EPA in recalc./correction of a mere 36 mpg...go figure.

My housemate drives a Yaris and says she gets low 30's MPG combined. I get mid 40's combined. It's very driver-dependent and VERY location dependent. My FX-16 averages about 40 MPG here, but I remember it occasionally getting below 30 MPG in the winter in Denver.

It might be fun to have two MPG benchmarks - the current one plus a "conservative driver" benchmark that reflects those of us who aren't road ragers. Might give people a heads-up about their wasteful driving habits.

[centrysis]

I drive conservatively, mostly town and country roads, and i've never gotten over 34 mpg. I only have 13,300 miles on it. I do have the 18" TRD rims, but that wouldn't affect it that much, would it? By the way, the sticker in my door says I have 185/60/15's on it when I actually have the 215/35/18's on it.

BUT, it's still a hell of a lot better than what I was getting in all my previous cars, with only slight modification to my driving style (doing around 65-70 instead of 80-85 on the highways).

I agree with all of that 100%. I filled up the other day and got my worst tank mileage ever since the first fillup when new. 32.5 MPG. All in town driving, with the air conditioning running at full blast much of the time. That's hard to complain about.

[BailOut]

That's just hard for me to fathom, Yaris Hilton. Even in the dead of winter, with a car full of adults and snow sports equipment, with the Spikes Spiders on and doing the traffic-laden run to and from the local ski area, I still get 42 MPG.

Granted, my engine grille block helps, but still...

[Yaris Hilton]

I doubt an engine grille block helps at all. You're probably not poking around in 25 MPH speed limits with lots of traffic lights, though. And little up and down hills where you have to put in lots of energy to climb, but have to take it all right off with the brakes, rarely benefiting from the downhill coasting. That's Bristol.

Last night I drove my Yaris with myself and my wife in it, and the trunk and back seat packed with all kinds of junk, across the Appalachians and over to the Atlantic coast driving speed limits on cruise control all the way. Mostly the speed limit was 70. Averaged over 43 MPG. Driving conditions make a huge difference.

I found wearing certain types of shoes helps with driving. I feel like I get better milage using my Shape-ups compared to using a light weight running shoe. I usually alternate between my dress shoes and Shape-ups when driving.

How would shoes effect shoe economy?

How would shoes effect shoe economy?

I imagine it may have something to do with sole thickness especially when driving a manual.

I have to sometimes drive with boots on and it kinda sucks. There's no "feel" of the pedals compared with wearing a comfortable sneaker. I have to concentrate more since I can barely feel the clutch. It's harder to drive smoothly.

Which all means that you may not be able to feather the pedals for efficiency without ideal footwear.

[KrazyDawg]

How would shoes effect shoe economy?
After driving a 95 Civic for a while, any newer car for me had a more sensitive gas pedal. I can find the right amount of pressure with the heavier Shape-ups than with wearing something much lighter.

[bkrownd]

Yeah, I definitely don't have as much control while shifting gears when I'm wearing my boots - my "touch" with the pedals is all wrong.

[yarrr]

That's just hard for me to fathom, Yaris Hilton. Even in the dead of winter, with a car full of adults and snow sports equipment, with the Spikes Spiders on and doing the traffic-laden run to and from the local ski area, I still get 42 MPG.

Granted, my engine grille block helps, but still...

I love story time. Tell me more.

[docB]

When myth busters ran the A/C vs windows down show...shame on them. They used Ford Exploders or something larger. They get the same mpg no mater what the condintions. Read terrible. If they used a genuine fuel efficient vehicle they would have had a better test. I had a 1989 Subaru Justy w/ a CVT. If the tire pressures dropped a few, I lost MPG. I got high 49 mpg on a road trip once. A pluged air filter showed a few mpg loss. The Yaris is such a vehicle. I do not use Scan Gauge. I have kept a log of all the gas through the thing since I got it. Overall to date is 39.8 iirc. High single tank is over 44.

The Ac efficiency on the Yaris really impresses me, I have compared my mpg
with it on or off,and I can Say that I have seen very little difference if any at all, compared to other cars I have owned in the past this is big Improvement.
On the Interstate highway With Ac on and roof rack and surfboard {9 1/2 foot longboard}
averging 73-76 mph I still easily get 37/38 mpg I am quite happy with that.

[newbieyaris]

Just bought my 08 Yaris sedan a couple of weeks ago for its supposed gas economy. I have now filled up the tank myself 2 times but have only seen 32/33 MPG. I was so excited to get 35-40+ MPG and am extremely disappointed. The car came with only 17,000 miles on it and as far as I could tell, was very well maintained.

My daily commute is 40-50 miles a day with 25 miles being on the interstate going 75 mph and the rest being dirt roads or city driving. Would the dirt roads make a big difference (going 40-50 mph)? However, I was able to take small trip (400 miles roundtrip) that was 85% interstate driving at 75-80mph and the rest city driving--was ONLY able to go 325 miles before having to fill up (gas flash came on) for a rate of 32 mpg.

Last night I filled up all of my tires from the dealers 30 psi to 35.5 psi. I also filled my gas tank at the same time to see if this would make a noticeable difference. Too soon to tell yet, but would love to have some advice on how to maximize my fuel economy so that it gets at least 35 mpg. I bought the car thinking that 35 mpg would be the minimum due to many of the reviews I read of people stating they get 40+ mpg consistantly.

Other factors:
Nebraska weather has been 15-30 degrees since I have bought it and thankfully no snow or inclement weather...yet. I am also not the softest driver ever, but since buying the car have tried to be gentler but I am definitely a work in progress :)

Would appreciate any help or ideas!

Only 32 MPG! HELP!

:iono:

The Yaris is EPA rated 32 mpg combined (29/35). So if anything, it's perfectly normal. Why are you shocked?

Also, it is winter and as you pointed out really cold. That drops mpg significantly. Wait until spring to really take a good look at what your MPG is.

The fact that your drive is half city and dirt roads should be a clue that you're not going to get 40 mpg. In your described conditions, you'll never get into the high 30's. That's perfectly normal and there's nothing wrong with your car.

:smile:

[Altitude]

It's the 75/80MPH that's killing you. Try 60/65 tops. Also, remember it's winter gas time and winter gas always gives bad MPG's.

[brg88tx]

[DevilGirl]

This is a significant factor in why your gas mileage is not as high as you would like to see, most likely your chief reason, actually.

[41magmag41]

with winters here in New Hampshire my mpg drops about 5 to 7 mpg. Longer warm ups to get the car to operating temp and I run four snow tires. In the winter I get about 32 to 34 mpg but during the warmer summers she goes up to 38 to 42 mpg.

[Idahotom]

I got enough warm weather miles on my recently bought '08 to believe the high MPG #'s, 38 to 45 with an average of 42 between fillups. A few miles of dirt road every day, with the rest freeway (60+ max) and 45 on the secondary roads.

Now that winter has really hit, and I have to have 4 wheel drive (busted through a 24" drift yesterday) I am back in the good old '89 Toyota All-Trac. I have yet to check a tankfull using the winter gas, when the weather improves I'll start driving it again, but I fully expect the MPG to be lower, due to the factors stated by others, but it will still be better then about anything else out there!

[CtrlAltDefeat]

cold air kills mpg.

Cold air does not kill mpg... moist air does. Cold air is more dense than hot air (the reason behind inter-coolers) and fuel burns more efficiently. Cold dry air gives mpg a noticeable boost, the car is even a bit more powerful with cold, dry air.

[tire]

UPDATE ON MY CURRENT TANK! CANT EVEN BELIEVE IT!

ok seriously this is all 50% mixed highway and city driving, and city driving is delivering pizza.

dropped the first bar at 93 miles
dropped the second at 160 miles
just dropped the third at 219 miles

will keep you updated on the rest of the tank, i would be blown away if i was able to hit 50mpg on mixed driving!!

Such a discrepancy between you and the average fuel economy makes me start to get concerned you are running lean or have a mechanical problem, potentially no bueno. No one said anything like this so I thought I would. Motors and cars do vary and I hope you have a ringer, but a red flag was raised in the back of my head. Let us know how it goes. :)

I can't count how many times I've read things like this (I'm sorry to say this but this is incorrect). It's quite simple, "colder", denser air is indeed pulled through the MAF or whatever air intake sensors are called on Toyotas. That sensor, um, senses more air and adds additional fuel to the mixture. At very best the mpg before and after will be negligible, at worst you WILL lose some fuel economy. I'm not sure how this myth permeates every automotive forum. It takes money to make money in this case, and I sure wish it didn't. :-)

Austin

[CtrlAltDefeat]

No, cold denser air helps mpg. For simplicity's sake lets say you need x amount of hp to maintain whatever speed. With hot air, the engine has to use less fuel per stroke, because the lower oxygen level but in order for the engine to output the proper hp and maintain the speed, the rpm has to go up. With the higher rpm being used to maintain the same speed, the hotter air gets worse mpg. Sure it uses micro-grams less fuel per stroke per cyl with the hot air, but every single additional rotation that it has to use to maintain hp uses an additional unit of fuel in each cyl...

[rningonfumes]

The RPM is related for the most part to the gear and the speed you're at. Most of us see the best mileages over the summer months. And this is even with the gas ratio changes some states are required to do.

When you get cold air, the computer has to compensate for the denser air...meaning more fuel to keep it at the ratio the computer thinks it's supposed to be.

If you want more power, sure take in colder air but that is not the route for getting better mileage.

texas wide open 75 mph most of the time. I average 36 mpg this car made to drive.

i am sooo close to 50mpg, i cant even believe it
Oh and i drive 55-60 on the highway, with DFCO whenever i have the chance. In town i take accelerations easy, upshift at about 2500 rpm's and try to keep it constant at 40-50mph. hard to do with all the lights though, even though that means more DFCO :).

A pizza deliverer that drives the speed limit. Didn't know that existed :o/

[ldinkinsjr]

when I first bought the yaris 09 i got 32-33 MPG, mixed driving around 75-80 MPH. Then I put an AFE dry cold air intake on, inflated my tires to 40 psi and got 33-37 MPG doing 75-80 MPH, I changed my oil to amsoil, 5w30 with high efficiency oil filter and got 37-39.5 MPG, then I changed my transmission fluid to amsoil, and got 42.8 MPG. So I tried to slow it down and let off the accelerator as much as possible, driving between 55-65 MPH and shot up to 48.9 MPG thats with the original tires (88000 miles) just got new Defender 185/60-15 tires on there now and hope my MPG dont drop any, hoping it gets better. My yaris is an AT.

[Shinare]

^^ Hmmm... maybe I should do the amsoil things to my 09. I'm getting 30-32 consistently. About to turn in a 27 or 28 tank.

Edit: What "high efficiency filter"?

Edit edit: Just filled up, got a 27.6 mpg tank.

[Shinare]

If I hadn't previously owned a 07 manual 3-door yaris I probably would be saying Yaris' were terrible at gas mileage. There's something wrong with my current one I'm guessing. Or the 09 AT yaris' really do suck at MPG.

Really good tips here. It almost sounds like an ad for amsoil but I've heard similar results in other threads. But to think that just by switching to amsoil, you've boosted your mpg by 30% is rather impressive.

With my 07 MT Yaris, I consistently get anywhere from 37-40mpg with 30% city driving and 70% highway. Depending on how fast I hit the highway, I can maintain a steady 38+ mpg usually. My hood is slightly up (long story) and someone stole my mirror cover so I know my aerodynamics are horrible. Not only that, I haven't washed the car in a few months...

My sister has the 10 AT Yaris and she tells me that she consistently gets low 30s 80% freeway in hers.

[Brett!]

I deliver pizzas with my yaris (still on my first tank of gas since I bought it..) and the first weekend I drove (about 200 miles over 2 days) I got between 38-44mpg the entire duration of delivery. I gotta say I am pretty happy with this car so far!

[JustPassinThru]

I don't know what you're doing to get this gas mileage.

With my 2009, with a manual, I got 38 mpg.

With my 2012, with an automatic, I'm getting 35 mpg. That's on pure gas, no ethanol.

Now I'm no lead-footed kid - I'm in my fifties and I drive...like an old fart in his fifties. I'm okay with the mileage but I'm not ecstatic.

Long time ago I had a Geo Metro 3-cylinder with a manual. I got 52 mpg with that. But that was about 800 pounds lighter - the added weight due to the newer safety standards.

[mirapatec]

Yeah, I wonder why some people get such poor fuel mileage figures. Even with numerous trips at Interstate speeds, I still obtain around 40 MPG per tank. I am extremely happy with this little car.

I am on my first gas tank at this time and am using a figure from my Automatic Link system - they may be giving me inaccurate figures. I currently have about ~335 miles with 2 bars left on the tank. If I do my math that is likely an average of 36mpg - still not bad, but my link had most of my trips at ~38-42 on most trips.

[nookandcrannycar]

I don't know what you're doing to get this gas mileage.

Part of it might be how flat this Houston metro is. Much of it is pancake flat. My Yaris has been in 46 states, and when I first bought my Yaris, I lived in the San Francisco Bay Area...and still visit. Houston metro = better MPG than S.F. Bay Area and many other areas.

Another factor might be the tire PSI level a particular owner is 'running'.

[Brett!]

after filling up it turns out I am getting exactly 36mpg. My link is either broken or not calculating correctly with the standard transmission

[Idahotom]

I am anal about parking in the shade during the summer, and often the tiny Yaris makes that easier. I'll back into a space rather then forward if it keeps the windshield out of the sun, and I use a sunblocker. Heavy tint, and a white Yaris. If I am going to be parked for several hours, I'll compensate for the changing sun angles so that when I leave the preheating is minimal. For instance: leaving in the late afternoon, I'll choose a spot that aims east, even though that is right into the sun at the time. My tank averages are always in the 40's, low to mid.

[47_MasoN_47]

The absolute worst MPG I've ever gotten was 27.x That was the first tank after I got my supercharger and quite a bit of time was spent at full throttle. I usually drive like I'm in Fast & Furious 9000 and still get 32mpg in town with a supercharged automatic sedan.

[yougojay]

Pizzas are delicious..


I have been getting 36 mpg just doing speeds between 30-55 mph. Probably averaging 45 mph most of the time. Have not even had it on a long-haul highway trip yet - 6,020 miles 4 speed auto :thumbup:

[jack black]

My daughter gets 28MPG in Yaris in city driving this winter. Now, she is also known to get under 40MPG in my prius while I get 50-60MPG, so I should say the yaris almost meets expectations.

[roxy1]

41.9 lifetime mileage. was higher but this winter has been pulling it down to about 40. 2014 5 speed. mostly light suburban and rural. 10-15% true city.

[cparker]

If you can get 50 plus mpg city, you'd be up there in Prius territory .

[cparker]

If you want to get your mpg thrills, set your trip computer before going down a hill on the freeway. Did that recently and my average for the next 25 miles was over 50 mpg. I stopped for lunch on the flats, reset it again, and I was over 40mpg the rest of the way home. I know that's kind of cheating, because you're not getting an average for the whole tank, but it's fun .

I've been averaging 40-41 MPG on my weekly work/errand commutes around town (approx 240-250 miles driven per week, fall/winter, no A/C). Manual 5-Speed 2015 here. During the hot Phoenix summer last year (110-118 degrees Fahrenheit) with A/C running, I was averaging 38-39 on the same trips.

[91mustang]

I get anywhere from 34-38 mpg, a/c on always, fast acceleration. 5 speed 2012 SE.

[Rigaud]

Just got back from an 800mile round trip with some mountains 1/3 of the trip. I did 45.7mpg and and I maintained a speed of 60-65mph. Same trip and same speed with my Audi A4 last week I couldn't get better then 24.7mpg.

[tmontague]

My commute is 90% highways minimal to no traffic (~100-130km/h) and farm roads on the way home with hard acceleration at all the stop signs on the way.

My last tank I just averaged about 5.7 L/100km. When I used to drive for optimal mileage my Yaris was getting 5.4L/100km but that was slow acceleration, going 100km/h on the highways and following trucks when possible.

That's why I love this car. You can drive it hard and still get insane mileage.

Fwiw, my Wife's '02 Echo with 381k km on it driven about 60-70% highways at 120km/h and not driven very hard it getting about 6.8 L/100km. Not too shabby for a car that's got worn rings.

A quick update to my last post. So for the past couple years, my commute changed from 22 miles per day (36mpg 90% freeway) to 15 miles per day (34mpg 40% freeway) to 13 miles per day (31mpg 100% city). Even on a 400 mile trip, I only averaged 38mpg (no ac, windows up, 80° weather, 95% freeway, 60-65mph, drafting behind trucks, pulse and guide). On a 600 mile trip, I averaged just shy of 40mpg (no ac, windows up, 70-80° weather at night, 99% freeway, 60-65mph, drafting behind trucks, pulse and guide).

My 2007 hatchback is all stock, 5 speed, no brake dragging issues, and I do slow starts, shifting around 2k rpm, utilizing all the hypermiling techniques I've learned (DFCO, pulse and guide, 42psi front tires, 48psi rear tires, going slow up hills, gaining momentum downhills, staying in the highest gear possible).

I just changed the oxygen sensor, pcv valve, oil filter, and flushed the transmission which will hopefully get me closer to the numbers I see here. I really have no idea how you guys are getting close to 50mpg in the city. Either your roads are all flat and you're getting up to speed then coasting with the engine off or you're running super lean. I was able to get 51mpg out of my friend's 95 civic vx on a 400 mile trip (60-65mph, hour long traffic, drafting behind trucks, with AC on 40% of the time) which is over 10mpg better compared to the Yaris so I know it's definitely not my driving habits.
