Fuel Economy

[tacsniper]

do you guys fill up when the last bar starts the flash or do you drive it a bit more?

[eTiMaGo]

you should really refill even before the bar starts flashing, as the fuel pump in the tank uses the gas for cooling. If you run very low on fuel, there is a chance of the pump overheating, which is certaibly not a good thing

If one drives "normally" theyr Yaris, paying no attention to saving gas, but just driving "normally" one will get in the high 20's and low 30's mpg at best. But if you are mindful about driving for saving gas, one will easily get mid to high 40's for hwy driving, and at least high 30's for city.

My Yaris has 715 miles on it. I just fueled up today for the 2nd time. I calculated my fuel mileage to be 40.33 mpg around town (no highway driving at all). I drive 21 miles each way to work with avg. speed probably around 45 mph. I have approx 15 stops for traffic lights. I'm not hypermiling but I try to be conservative (no jackrabbit starts, etc.). I'm very pleased so far. Will my fuel mileage increase as my engine gets broken in?

Good numbers!
Hopefully, you will get even better numbers as your car breaks in.
Although you are not hypermiling, you are paying attention not to waste fuel unnecessarily, if this is what you meant in your post. I think that is the main reason why you get reasonably good numbers. As I have been saying, anybody paying attention to F.E and fuel saving techniques will benefit to a degree.
Also, although you said you did not drive on highways, you did say that your average speed was around 45 mph, which I consider faster than the usual speeds we use in city traffic. So, it appears that you have not always been bothered by busy traffic. Also, you said that you drove about 21 miles each way to work, which should be considered a long but quite smooth, albeit non-highway trip. Although you mentioned that there were about 15 traffic light stops each way, you could have been using anticipatory techniques to avoid some traffic light stops some of the time, consciously or otherwise. I think all these contribute to the fact that your Yaris has returned more or less highway fuel economy.
Short trips and bumper to bumper traffic are very damaging to F.E.
I recommend this site to you. It is very practical:http://www.vehicleservice.co.za/calc/fuel.html. Unfortunately it appears that it uses Imperial gallons in its fuel calculator. However, the fuel saving tips in there are good. If you use them, you will not have to rely solely on the car's breaking in to bring you even better F.E.
Warm regards and safe and happy motoring!

Swng,

Thanks for the feedback and the link to that web site. I kinda felt like I was more towards highway mileage based on my daily driving conditions. You confirmed my suspicion

[jh3cuemd]

Yaris 3D 1.3.

I'm getting 60 Km/g (38 mpg) in city and 65 Km/g (40 mpg) in Highway.

I life in an city (Cuenca, Ecuador) which is at 2200 meters of the level of the sea.

I drive under regular conditions and roads, no modifications in my car, ocasionally use of the A/C, drive under 80 km/h in city and under 130 km/h in Highway, no special care in driving (like some strange technics I saw in last posts) (althoug I drive safe and responsably, and being a car lover myself I don't over rev the engine or abuse the brakes and clutch), regular oil change and care (only at Cuenca's Toyota Dealer Importadora Tomebamba which I think is the best), only premium fuel. The car is manual.

Before this car I had a Suzuki Alto 2003 (1.0L 67HP 16 VALVE), that car gave me an average of 75 Km/g (47 mpg) in city and highway, which I think it's truly great.

I think the mpg I'm getting with the Yaris are totally more than OK, I'm really happy with my car.

The price of gas dipped down so I thought that I top off my tank even though it was only half empty. For 179.4 miles I used 4.004 gallons for a MPG of 44.8.

I just put synthetic in it and my tires are right at 40 psi. I'm slow to takeoff and utilizing DFCO where ever I can; other than that no special tricks!

It's kind of rough here in Michigan where the speed limit is 70 mph. It seems like I do so much better on the back roads where I can set the cruise at 55 mph. I want to bump the tires up to the 44 psi max and I'm considering blocking off some the space in the grill for better aerodynamics. I'm a little leary of shutting of the vehicle at any time where it is still moving. We're still taking this a little bit at a time.

It's an awesome little sedan at any rate.

For some reason the mileage is always higher when you fill it when it gets half empty. I don't know if the last half a tank goes faster or what?

[roxy84]

im sure this has been discussed a million times, so heres one million and one. its difficult to get an accurate reading of mileage with barely a half tank used. the smaller the total mileage you are dividing in to, the easier it is for any variance in the fill to affect your outcome. the way you fill on that particular pump and the peculiar characteristics on that pump can really skew a small numerator (mileage total). i always get a chuckle when someone says "i got 50 mpg on my car. i went 50 miles after filling, then filled, and it took 1 gallon to refill."

while its not good to run your tank near empty too often, it is the best way to get the most accurate mileage reading on a given tank.

I must say, I'm really happy. Now if I can only get the 34 mpg that they promise for city driving; my 1st tank with 95% city driving got me 30.4 mpg. I was a little disappointed with that, but I don't know how full the Toyota guys and gals filled the tank, so it might have been half a gallon or so shy of full -- that might have made a 3.6 mpg difference; we'll see.

Okay, on my last tank, on 60%city, 40% hwy, I got 38 mpg; I'm really happy about that reading. As I mentioned above, I was very impressed with my all-hwy mileage on my recent trip, getting as high as 46+ mpg, with a full load and 3 people. Very impressed.

I'm about 2500 miles into my car, and have been locked at 37 mpg. The only tank that was above that was 41 mpg, with my girlfriend driving. I don't understand that, as she drives my Yaris like her Prelude SH, so I would think the empeegees would drop, but not so. I even got the same mileage on a 700 mile trip cruising at 80 as I do with my daily 40 mile 60 mph commute...

Maybe I'll get a stick up my ass and try to get through a whole tank with my mind on the highest empeegee, but probably not...

Be careful Mr. Attitude, fuel saving techniques are highly addictive !
Nice initial numbers! Please do make further reports of your "empeegees" here.
Safe and happy motoring!

Impressed and feel happy for you! Share more of your experience anytime!

[sherryberry]

Well, my first tank was at 35 MPG with all city driving. then the next tank was at 32 MPG and the only reason for that is because my bf was driving it going 90 down the highway and just accelerating like crazy. This past tank, I got a good 36MPG.. again, all city. I drove a little highway on this new tank so we'll see how I do.

[marcus]

youll do better if you dont let your bf drive it..hehehe just a thought!

[leowhy]

just a brief update:
my latest tracking... 14.39km/L, 60% highway, 40% city driving...

[adamschneider]

I just finished a tank that was about 34.5 MPG (US), but given that it's been hot and I've had the A/C running a lot -- plus it was mostly city driving -- I think that's not too bad.
