Fuel Efficiency and the Yaris

[Rigaud]

So you all are getting 400+ miles per tank? Crazy......

Sent from my metallic purple honami

360-395 miles per tank this winter on snow tires and cold. I'm about to find out what I do on summer wheels. I just drive, not going nuts trying to suck every possible mile out of a tank. If I compare with my Suburban or Audi A6, it's awesome. ;P

[roxy1]

as bad as this winter was, with much colder than average temps and 122 inches of snow, my average for december 1 through april 1 was 40.9 mpg's. now that summer gas is here (along with warmer weather), I expect to be closer to 44 mpg's.

5 speed manual. mostly suburban/light suburban/rural driving with speeds usually ranging from 40-60 mph, with about 10-15% true city driving.

I do not hyper mile. I do drive reasonably and avoid blasting away from every stop.

I never run past 2 bars and I'm getting almost 400 miles before fillup, if I ran to empty that would be almost 500 miles out of the tank based on my average.

[trunkout]

I've gotten 45 miles to the gallon. Hypermiling and driving 55. What's the big deal? It's even a sedan. It's technique, plain and simple.

Imagine there is an egg on your excellerator and you have no brakes.

527.9 miles on my last tank (filled up yesterday). I'm the oddball, as I fill each tank until I can barely see the gas in the neck...0.023 gallons from maximum capacity. I know that because I once ran out of gas as I was pulling into a gas station and it took 12.777 gallons to fill to that point. I know that is 0.023 gallons from maximum because CTScott performed a test to figure out the maximum capacity (don't remember how long ago that thread was posted), and the maximum is 12.8 gallons. My last 6 tanks:

527.9 miles ----- 11.784 gallons ----- 44.747114 MPG
517.2 miles ----- 12.164 gallons ----- 42.518908 MPG
504.9 miles ----- 11.994 gallons ----- 42.096048 MPG
517.7 miles ----- 12.347 gallons ----- 41.929213 MPG
490.3 miles ----- 11.550 gallons ----- 42.450216 MPG
483.3 miles ----- 11.506 gallons ----- 42.004171 MPG

[Amdkt7]

I was getting 50 mpg for most tanks last summer. I don't have the patience for it now, I get home 10 minutes faster and still get 43 mpg per tank.

The big trick for me is to put in the clutch and coast as much as possible, try to time traffic lights. Driving over 70 kills the mileage. Short trips really suck gas as the engine is not warmed up. I understand the engine runs rich until the catalytic converter gets hot enough to work.

Also, do not dally when getting up to speed. All time wasted in the lower gears really suck fuel badly. Get into top gear as soon as possible, then go with a light foot.

I drive a stick, and that makes a lot of difference. When coasting (even with the engine on) the gas mileage soars. It you are stopping use engine breaking as that causes the fuel to shut off completely.

[why?]

I haven't lived in Florida, as Shroomster does and you did, but I've probably spent more time there over the last 8 years than in any state but Texas and California, and I've been all over the state. In my experience, your statement above is definitely true re Shroomster's area (the Orlando area). Re my experiences, if Shroomster lived generally anywhere south of an imaginary line drawn between Bradenton and Fort Pierce, I could see what he's saying in his last post being the case (especially on I-75 between Bradenton and the western edge of Alligator Alley)....but the craziness could have finally migrated up his way.

I agree with all of your suggestions (in other parts of your post) re improving MPG.

I like aggressively going slow, meaning if they get right on my ass I just slow down more. I learned to drive in Boston traffic. Talk about horrible jerks. The angrier they got the slower I went.

:thumbsup: - Harder to do here (and impossible to do as effectively) re the pancake flat nature of most of the terrain ('The Heights' neighborhood in Houston got it's name re the elevation being 23 feet (yes 23 feet) higher than Downtown Houston, LOL).

Get into top gear as soon as possible, then go with a light foot.

:thumbsup: I do this as well.

coasting (even with the engine on) the gas mileage soars.

I used to turn the engine off at a few red lights, but I stopped doing that as my revious battery got toward the end of its life.

[nookandcrannycar]

I feel for you. Last year (IIRC), I was describing driving in South Florida on a thread here. I wrote something about drivers in Boston being self involved, but that it is a different kind of self involvement than that displayed by drivers in South Florida. That amused another member (MA redident, IIRC) who is familiar with driving in both places (don't remember who it was....pretty sure it wasn't you) enough to subsequently post a reply to the thread.

east coast drivers....when I moved to CT in 1990, I learned my first day how fast a driver behind me can honk their horn when a light turns green. I swear they must have their hands on the horn just drooling with anticipation.

ive lived in MI, IN, CT, AZ, IL (Chicago), and Japan. the east coast drivers, without doubt, are the most inconsiderate, angry, unskilled bunch.

sorry if I have offended any east coast dwellers....just don't get too angry and end up running someone down.

The only part I disagree with is unskilled. They are great when everyone on the road is acting as aggressively as possible in a me first way, and everyone knows it.

They are horrific in any situation where that is not the optimum driving solution or there is someone trying to be nice. Add that to roads that cannot possibly handle the number of drivers on them, and you pretty much have hell on wheels. Now there are always idiots, but with the above mindset you just assume they were doing something meaningful to only them.

But you can call these morons anything you want. The USA would be a better place if 90% of people in the northeast corridor did not ever exist.

:laugh: Yea, the my time is more valuable/the world revolves around me type of self involvement is prevalent in many areas up there. it's worse that way, in my experience than the SF Bay Area or such parts of the L.A. Metro.

In 2006 (?) I was doing some shopping at the little Rye Ridge Shopping Center (Westchester County, NY). I turned left out of the shopping center and meandered down the road. I continued under I-287 and up to what was then (now =?) a 4-way stop with 4 stop signs. This is the intersection of Polly Park Rd and Purchase St. It lies between the Westchester Country Club and I-287. The stop signs are set pack much farther apart from each other than normal stop signs. IIRC, each street is 2 lane and has a double yellow. As I pulled up to the intersection there was some traffic and I heard some honking. Two women (obviously friends) in their convertibles(tops down -- BMW and Audi, IIRC) had pulled into the middle of the intersection and were just sitting in their cars, engines on, justr gabbing away. People on all sides of the intersection were honking and trying to navigate driving around them and flipping them off, and they were just ignoring everyone. One of them had obviously just ended a tennis match (had to have been at the WCC). I finally got around them, making a left turn. In 2007 Tiger Woods refused to play at that stop on the PGA tour. I heard it was because he didn't like the attitude of the people there. I thought about those two ladies in their convertibles and laughed.

Last October I was in Asheville, NC. The particular brand of liberalism there was not to my liking. I got into a conversation in the Starbucks parking lot with another person from Texas who saw my plates and struck up a conversation. We weren't giving any indication that we were leaving. We were getting people stopping, honks, and people angrily asking if we were coming or going. Each one looked unhappy. The last time I was in the Bay Area, I was on BART train. I've been riding BART trains since the 1970s. I was really taken aback by how unhappy a majority of the people looked. I don't see/come across scenarios like either of these in my neck of the woods in Texas.

I will concede some of them are skilled...but then again, so is an assassin working for the CIA.:smile:

[caruso125]

I just bought a 2010 Yaris with 52k miles and I'm considering changing from conventional oil to synthetic, what do some of you recommend, and also considering using the E3 spark plugs and K&N air filter, I went to the dealer to ask for there opinion and they really didn't want to say yes or no on the oil and plugs because I guess they think i'll hold them accountable if any problems happened. I guess I should mention that I live in Florida with hot weather!

Thanks Mark

[WeeYari]

Oil - I'm not entering into yet another debate on the subject
Plugs - there is absolutely nothing to be gained by swapping to anything new or different
Filter - K&N is great provided you have the discipline to clean and oil it properly. The OE filter is however, a fine filter.

Well I guess if I try them out and see improvements I won't share if it bothers you.

[nortonfb]

Synthetic is fine. You can get a oil war going easy.
I have been using Mobil 1 but next time it will be Total synthetic.
Why? No real reason.
Good luck.

As a new member I'm exploring the site and found this thread. I did read through page one but it would take me an age to go through the whole thing. As a former driving instructor there were many tips in the original posters text that are well known to me in regard to fuel efficiency and I've practised them for years.
My 1.33 VVTi 6 speed manual which I owned from new in 2010 to 2013 showed I averaged 55.40 miles to the gallon during my ownership of it. I believe I'm right in saying this translates to 46 miles to a US gallon. The Yaris gives pretty decent consumption figures in my opinion, especially if driven with a light foot.
After a year without one, my second Yaris is being checked over by the selling garage. Not new this time but she looks great and I'm really looking forward to having a Yaris on the driveway again.

[Yaris Blue]

After four and a half years I finally made it to 50 MPG. 104 fill ups... 41,331 total miles... 824.68 total gallons. 50.1 MPG!

:thumbsup: Incredible! My overall average is probably right at 40, or perhaps a bit above. I don't even have one tank at 50!

[ezhacker1]

With DFCO and P&G extended time on all freeway i can get 48-52. depending on the terrain.

[albee213]

I am just learning some of these techniques using the Scangauge II and changing driving habits. I think its funny becuase I have been able to reach 45 MPG TRP AVG in heavy stop and go traffic but only 35 TRP AVG in free flowing traffic conditions.

Wow. my best tank = a hare under 49 MPG from Winnemucca, NV to Mill Valley --- I-80 to Hwy 37 to 101.

[roxy1]

Wow. my best tank = a hare under 49 MPG from Winnemucca, NV to Mill Valley --- I-80 to Hwy 37 to 101.

yeah, even though my lifetime average is over 43, I have never gotten 50 on a tank (probably 49.2 or somewhere around there on a flat trip of 45-60 mph). I believe if I employed hypermiling techniques it would be very doable

[why?]

I just had a tank that was 49.9, and fuelly averaged it up to 50. It was 49.989 or something like that. New tires are wonderful for gas mileage, and no dfco at all. Just neutral coasting and some turn the engine off at red lights.

What a shock, tires make a huge difference.

[albee213]

I just drove from Seattle WA to Sacramento CA and only averaged 34.79 with a high of 40.09 getting 421.3 miles on 10.51 gallons, thought I was going to run out of fuel at that point. I was hoping I could average closer to 40mpg but it was hard to maintain lower speeds, I drove average 70 mph.

I think weight played a big part of it, my cousin was with me and he is a big guy, so am I, I weigh in at 250 and he is 270, other than that we didn't have much stuff.

[Amdkt7]

Interstate driving is not the best for Yaris gas mileage. I do much better at 45-50 mph. Cooler weather is making it harder now.

[matti]

Yes, I've also noticed a substantial drop in mpg due to lower temperatures (as expected). In the dead of winter, my mpg probably drops 20-25% over summer mpg. (I do believe winter blend has an effect, too.)

[Hershey]

Most likely you have the winter blend as well . It started the beginning of October here .

[yarisjoe]

I am fresh driver, have yaris for a year, at open road, not free-way, made one trip, about 300 miles, and cpu show 56 mpg, but real mpg was 50 mpg. And in past year I made 6000 miles.

:thumbsup:. Which model year is your Yaris?

[Amdkt7]

Since my driving has returned to near normal I am averaging 43 per tank in the summer, and 41 MPG per tank in the winter. The best roads are still the ones where I can drive 40-45 MPH and have lots of opportunities to coast. The engine is more efficient under load, doing work, not at a light cruise. Hence the pulse and glide technique. Hilly terrain creates a natural pulse and glide, provided that you either coast, or you take your foot all the way off the gas while still in gear going down steep hills. I love the ride down off the mountain coming back from Chattanooga, I can stay in gear much of the way and watch the Scan Guage read 9999, and see the average mpg soar!

Hi guys, I have a yaris 2007 1.0L (Japanese version). I drive it here in Karachi in heavy traffic with high stop and go frequency. i am getting 26 mpg only while i am reading 40 MPGs or above in this thread.

Is my mpg fine or is there something wrong with my car.

[IllusionX]

It's about right for stop and go traffic. I get about the same with my 1.5L in city only driving.

[nookandcrannycar]

It's about right for stop and go traffic. I get about the same with my 1.5L in city only driving.

My worst tank (all city) re my '07 = above 32 MPG, but I still agree with you. I made a trip to The Galleria (the 8th largest shopping mall in the U.S.) in Uptown Houston a day or two after Christmas. Big mistake. The specifics of the traffic jam I experienced made it impractical to turn the engine off at all. Before that trip, I was way ahead of my previous tank re fuel economy. After that trip...no way.

I wish that engine :wub: had been made available in the U.S. My 2001 Suzuki Swift (the car I had before my '07 Yaris) had 70 HP. With the 5-speed manual transmission, and low curb weight, that was more than enough.

Past weekend I made a trip long 375 miles and spent 30 litres or 7.9 US gallons. Computer shows 4.4 l/100km or 53,5 mpg but real is 47.8 mpg it was open road but freeway only 25 miles, average speed was about 42 mph but conditions of road do not allow faster driving, four of us was in car. and at freeway (fuel burning part of route) had additional 220 pounds of weight and max speed 87 mph ;)

[nookandcrannycar]

but real is 47.8 mpg

:thumbsup:

average speed was about 42 mph but conditions of road do not allow faster driving

:eek:

[nookandcrannycar]

I thought the last two tanks on my 2014 dipping slightly might be because of cold weather. I checked the tire pressure at all four corners today. I now think low tire pressure (:eek:) was a factor. I wish the TPMS trip threshold PSI was higher.These tires don't seem to hold pressure as well as any I've had on my 2007. I wonder if this is because the are the crappy Goodyear Assurance OEMs that many USDM 3rd Gen owners complain about...or if it is because the dealer inflated the tires with nitrogen and included free refills from the dealer (the benefits of the PAC sticker were still included even though they took the PAC sticker off the price before listing the car on cars.com)

I had a Suzuki Swift before my '07 Yaris. I took that car on the car ferry from Nova Scotia to Newfoundland. I drove over 2,000 miles around Newfoundland. In rural areas I sometimes encountered roads where speed (irrespective of the limit) was limited re bad road conditions. Most of these roads were unpaved (no asphalt nor concrete), and some had horrible potholes. Later in the trip, while heading west on the Massachusetts Turnpike, I realized my steering rack was just about shot and I could only put about 500 more safe miles on the car (it already had 151,000 + miles on it). I plopped myself down in Chicopee and started searching dealer websites for the right Yaris. If the Cars.com site with the advanced national search function was available at that time (as it was in 2014 for my 2014 Yaris), I didn't know about it. This was in 2006 and Cars.com had only launched in 2004. I searched hundreds of dealer websites and only found 5 new Yaris cars with manual transmissions. I bought the first one that I actually found in inventory. :smile:

Why in America most cars are with automatic transmissions not manual, here in Bosnia no one doesn't even think about automatic transmissions? And I know that car with automatic transmission has lower MPG.
After my long trip I fill my tank to the top and till now I made 194 miles (124 at open road and 70 miles in city) and I spent 15,75 liters of fuel and get 45 MPG. And I am more than satisfied :headbang:

:thumbsup:That is an extremely good question. It's sad. I wish we were more like Bosnia in that respect :thumbsup:. I think laziness and an unfortunate growing tendency toward people wanting to take the easiest (but what might not end up being the most satisfying) option. It is also harder even if kids want to learn how to drive a manual because there don't seem to be as many cars so equipped available. Within my whole family on both sides, I think every driver over age 30 knows how to drive a manual as opposed to zero under age 30.

[Ben_]

Manual is the best. I hope to never own an automatic but since autos are more popular some cars don't even come with a manual

[thewickett]

new '12 5dr hatch owner here.

Using pure gas here and some mild hypermiling techniques (+ or - 5 mph of the speed limit depending on momentum), I've seen highway trips between 37-43 mpg and around town trips ranging from 35-50 mpg. This car is super efficient in 4th gear and 30-40 mph speeds.

I knew gas mileage would be higher than posted, but now I'm really glad I didn't pony up the extra cash for a prius c.

[Yaris_Mac]

I bought this Yaris 2 years ago with 33k miles in it. Everything was OEM including the tires and I was getting 35 MPG city/hwy (8am-5pm M-F in the Bay Area) at 55 MPH. After owning it for a year, I changed the tires to stock OE Miata wheels+tires 14x5 with 195/60 and my MPG dropped to 34. Then I had the throttle body & injectors cleaned... That was 9 months ago. I am now getting 36 MPG and it doesn't matter how I drive it. I stay 70-75 sometimes and most of the times I don't go on the freeway because of the traffic on 880. I still get 36 MPG on my 14" wheels!! Drive from NorCal to Reno I get 39 MPG. Reno to NorCal I can get 45 MPG. That's at 65+ MPH.

[cparker]

I'm wondering if the repeated shutting off and starting engines at stop lights might drain the battery and wear the starter motor . When I had a paper delivery route, I did this and it caused problems .I could see doing this at known long stop lights. Also shifting an automatic to neutral at lights while running the engine may reduce a bit of consumption.

[Ilovemyyaris]

So after a few years of owning I generally averaged 41 mpg mostly a combined highway/sort of city driving. heavy traffic drops to the 30s depending on lots of conditions.

Long slow 40ish mph backroad driving gets me close to 50mpg. Usually about 49 tops both ways. Only going mostly downhill can I get over 50 ever. Some people have claimed to get over 60mph but if they're telling the truth they had to have been going downhill the whole time or did some car modifications, at least if they're driving an auto transmission, maybe sticks can get better with the extra gear but high 40s is where I top out no matter what I do, how I drive, literally no hitting of brakes till I arrive at my destination. 50 is as good as it will get for me. I might so some minor mods later. Thinking about taking off the hubcaps soon.

[ncp13]

I am no eco driver specialist and I can only report the worst milage you can get :biggrin:

From experience I can tell you that for a 500km trip with an average trip speed of 140km/h my 01 Yaris TS averages 28mpg..

That trip includes steep uphill highway roads, long stretches and frequent toll stops.

You get the same milage driving like an ass in the city with a lot of traffic light drag races..

[Minus8]

I have 1.4 d4d 6 speed and go to work at 80-90 km\h and make some city and highway. Fuel consumption 3.9 L\100 in Summer and 4.2 L\100 in winter ��

[GibbsYaris07]

As far as my MPG, since I use this vehicle for 4-6 hour work commutes and travel, I avg. 36-37 mpg driving in hilly/mountain terrain (75-78 mph). I believe I could hit 40 mpg on flatter roads, driving lower speeds. With that said, I'm happy with my performance but always looking to increase mpg. I'm planning on changing the spark plugs and cleaning the fuel injectors. Maybe that will increase my gas mileage.

[richardsimmons]

My average MPG is between 28 and 32, with a constant mix of city, hills, and highway miles.

The lowest I have ever gotten is 21, and the best I ever get is 36.

This is in Northern California.

[DiCaprio]

Winter just began in Germany. I usually get around 35 mpg in the summer. In the winter I get around 31. There is lots of city driving in my mix thought. Like 90%.

[07liftback]

Went from 34mpg mostly highway to 28-30mpg mainly city driving. 34mpg was with 12 mile one way routes and 28-30mpg is with 5-6 mile one way routes. I had purchased some Denso spark plugs off ebay a couple years ago when I also changed my route, so I'm not sure if it's done anything to my mpg since I recently read that many spark plugs on ebay are actually counterfeit. I'll need to put my old ones back in and see if there's a difference in mpg.

However, driving like a granny from San Francisco to Los Angeles (400+ miles), I'm able to get 40+ mpg. Keep in mind that this includes drafting behind as many trucks as I can find and filling all my tires to above 40 psi with zero braking. Consistent 50-55mph on the freeway. If I drive normally from San Francisco to Los Angeles, I'd get about 30-35mpg (65-75mph). Not sure if there's something wrong with my car as it seems that my car is doing 20-40% worst than everyone else in this forum...

[jared8783]

I haven't read all 18 pages. And I'm aware I'm not the first to address this.

I'm shocked that a sticky in the OP encourages people practice not only dangerous (as pointed out) but a costly method of raising mpg. Over inflation of tires. NEVER inflate your tires to what the side wall says. Your tire is designed to fit multiple vehicles with varying air pressures. The sidewall is simply the max the tire can handle. Inside the driver door jam it tells you what Toyota says your tire pressure NEEDS to be. Shockingly, the engineers knew what they were doing when they designed the car.

I've spent 2 years as a tire tech before I was 21.

Not only as someone said there is higher risk of separation. But if you over inflate your tires you are GUARANTEED to wear out your expensive tires prematurely. Since you are putting most of the rolling pressure on the center area of the tread your tires center will go bald fast. Is saving a few bucks at the pump worth spending hundreds more on your tires? Economically it doesn't make sense. And we love better mpg cause of monies. So this just doesn't make sense.

Safety. Since you aren't putting even pressure on your tires footprint you are drastically reducing traction. Your stopping distance is increased. Which may just be the difference between a near miss or a fatal accident in an emergency. Once again, I'd like to point out that the engineers at Toyota knew what they were doing. Shockingly.

If you do want to ignore all the economical and safety reasons not to over inflate your tires here is one more thing to keep in mind. It improves mpg by reducing rolling resistance. Which ONLY in the city. This has been studied. Somewhere between 30-40 mph rolling resistance has a negligible effect on mpg and the only resistance that matters air resistance.

On that note I'd like to encourage forum mods to alter the OP to no longer encourage drivers to practice dangerous and expensive methods just to save a few bucks in the short term.

Went from 34mpg mostly highway to 28-30mpg mainly city driving. 34mpg was with 12 mile one way routes and 28-30mpg is with 5-6 mile one way routes. I had purchased some Denso spark plugs off ebay a couple years ago when I also changed my route, so I'm not sure if it's done anything to my mpg since I recently read that many spark plugs on ebay are actually counterfeit. I'll need to put my old ones back in and see if there's a difference in mpg.

However, driving like a granny from San Francisco to Los Angeles (400+ miles), I'm able to get 40+ mpg. Keep in mind that this includes drafting behind as many trucks as I can find and filling all my tires to above 40 psi with zero braking. Consistent 50-55mph on the freeway. If I drive normally from San Francisco to Los Angeles, I'd get about 30-35mpg (65-75mph). Not sure if there's something wrong with my car as it seems that my car is doing 20-40% worst than everyone else in this forum...

Greetings from SF! We have similar driving habits, it seems. I probably do ~ 60% of my driving city (SF) & ~ 40% highway.

The worst tank I ever had was 21 MPG, while driving for Lyft in SF, in the winter. (Hope I never hafta go back to that side-gig!)

The best tank: 37 MPG, en route to either LA or Joshua Tree. I was happy as a pig in shit. :headbang: Also: I drive between 65 & 80 MPH on the highway.

Although I do a mix of driving, I usually average 27 in SF, & 33 highway.

I'd call it ~ 30 MPG overall.

No clue how these lucky bastards on the forum are **averaging** 42 MPG haha!

Hello all, this is my first post. I'm about to but a 1.3 hatch t-spirit. I have experience of the Yaris. I like them a lot but I like all Japanese machines. Having just glimpsed through this thread, I'd thought I'd tell you of an experience I has with a former car, a Ford Mondeo 1.8 diesel (manual transmission). This is a euro car, not the one sold in the USA with the same name.

When I bought it, it became apparent that the dual-mass flywheel was giving up the ghost (with a mere 50,000 - not impressed). The reason why seemed clear - the 1.8 litre engine was a gutless POS and needed a big boot to get anywhere, and the drag starts had killed the flywheel. So did I change the car? No, I changed the flywheel. Obviously.

I drove the car within its limits for another 300,000 miles - painful, boring miles - but my sedate careful pace returned easily 60mpg on the motorway and easily 50mpg around town.

The car eventually expired at 350,000 miles when something called a 'wet belt' snapped (similar to a cam belt but since it ran in an oil bath Ford decided it didn't need maintenance and thus didn't mention it in the service list - curse them). The clutch and flywheel were still good.

I checked tyre pressured when I thought of it. I kept the boot (trunk) mostly clear of junk. I made nice smooth gear changes and didn't rev the tits off it - no point, it had nothing to give - and tried to anticipate braking. I drove everywhere and in all conditions.

Conclusion - your right foot is the biggest factor in achieving high fuel economy. For some this is a an unacceptable truth. Even 30 mph is a lot faster than walking, folks. Also, auto transmissions suck up power and use more fuel than their manual shift equivalent and are used chiefly by lazy witless idiots who can't drive properly.

I have 1.4 d4d 6 speed and go to work at 80-90 km\h and make some city and highway. Fuel consumption 3.9 L\100 in Summer and 4.2 L\100 in winter ��

My 5 speed 2007 1.4 D4D does 4-5l/100km in summer and 4 - 4.5l/100km in winter becaus the speed limit is lowered then. My car has rolled over 400,000 km though. I once got it down to 3.7l when driving in winter, just straight on country road from work to home.

Just came back from a longish trip, collecting someone, I hit the dashboard left button knob to change the clock but got MPG miles per gallon average, it initially said around 53 now says 52.2

This is better than expected, although I was doing around 55 MPH a lot of the time.

I think normally on the Urban cycle (lots of short trips) it is returning around 40 MPG

[sh0rtlife]

NEVER believe the vehicle ECU estimated number...ive never seen a rig that was remotely accurate

if my wifes driving..she can get anything up to 32 city and 42 hwy..which still blows my mind since that was with a small trailer....but the numbers didnt lie and she has repeated it without the trailer several times over the exact same route

me on the otehr hand..i averaged about 27 be it hwy or city i seem to only go up or down a smidge ie 28.8/26.4

its an 07 5dr automatic..with a lil over 100,000 miles on it...im very convinced the manual would get much better mpg for me atleast

one thing i did find tho is that hard hills and heavy loads will cause a need for premium, but premium run "long term" will drop the mpg down to 24...by way of the brain re-tuning...topping off half a tank with premium will eliminate the pinging of hills and wont effect the mpg...seems to only be an issue in cold weather combined with steep hills an additional 300+lbs in the car

[Martin Bruce]

After another recent long trip cruising / urban I managed
53.2 MPG AVERAGE. (Sorry about bad photo).
I don't think I am going to get much better than this.

I would love to get a Toyota Hybrid next - 100 MPG I read somewhere?

With the Yaris I've found the biggest factor is where you drive.

Doing 70 instead of 80 on the highway gets me 37 instead of 36 mpg.

In the almost 10 years I've driven the car 75 miles each way on mostly highway to go to work, I've gotten 34-36 mpg (34 in the winter when driving on studs).

The first few years I had the car when I lived in NY I routinely got under 20 mpg. If I didn't do any highway speed (vs. going 10-15 mph on the highway) driving I would get about 15 mpg.

[bronsin]

The 1.8 L engine of my 2020 corolla with it’s newfangled variable speed transmission will get 50 miles per gallon at 60 miles an hour on the highway. It’s no trick at all to get 40 miles per gallon in town. Just imagine what it would would get with 1.5 L engine.

[sh0rtlife]

sorry to say it..but the 1.8 is a MUCH better engine, and honestly that same 1.8 in the yaris would probably make even better than 50 being half the weight of the rolla that same engine would be working half as hard to do the same job....

theres a diminishing returns of weight vs CC....and while the yaris has a sweet spot if you drive it like a lil ole lady the same light yaris with a 1.8 could only get better mpg even when driven angry

I get 28 city and 32 Hwy the best I have managed is 34 highway driving about 67 cruise control. I thought something was wrong with my car. I have denso iridium plugs from Oreilles.

*everyone else with a yari* "im going to drive to be fuel efficient"

*me, running premium gas, foot to the floor through every gear change* "what fuel efficiancy?" :burnrubber:

[GaryInony]

What specific factors or modifications might contribute to the difference in fuel efficiency experienced by users with similar Toyota Yaris models, as discussed in the forum?

[Amdkt7]

I have made no modifications, yet get 40mpg tank after tank. 2013 HB LE, stickshift. Mostly it is driving style. Coast as much as you can. Downshift to brake, because when engine braking the fuel is shut off. I accelerate like a rabbit, working to get to 5th gear. I usually go from 3rd to 5th. Once in 5th I then drive with a light touch on the pedal.
If I am doing 100% highway speeds (+70mph) my mileage will not be as good. The Yaris loves country roads that go through hills, as long as you don't have to slow too much for curves.
I'm at 190K miles. No repairs. Just changed the rear brake shoes, the front pads are still fine.

[Keith Mitchell]

Hi All. In reading the OP, and him saying he never goes over 2000rpm, my 2014 YRS at 65mph, the maximum speed limit in Australia is revving at 3100rpm. Is this normal or has my Yaris got a mechanical issue? I would suspect at 55 the revs won’t drop much and definitely not to 2000rpm? So downhill under brakes my Yaris downshifts (auto). Also have a 2012 Camry at the same speed is doing 2200rpm..

[SeaYa]

Hi Keith - revs/mph you indicated seem right on. MT is around 3000 @ 60mph, so that tracks. Not going over 2000RPM could be interpreted two ways: in 5th gear never going above ~50/55mph, and/or always up shifting at 2000RPM to keep overall rev average low. I do that myself as most of my shifting on daily commute is on flats and rarely go above 2k other than the big uphill on the way home, but even then, 3rd gear at 35mph is barely above 2k.
