Fuel Economy

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

Unfortunately the Yaris I purchased came with damaged paint, but I am getting a new one to replace this one. In the mean time I am very happy with my fuel consumption so far on this damaged Yaris.

I'm not going to get an accurate fuel mileage estimate with this car, because I'm not going to be keeping it long enough to fill up the tank when the dealer filled tank is empty.

I've got over 600km on the yaris now and still have 2 bars, I think it will be down to 1 soon, but still, if I had no gas I'm at 7 l/100km on a brand new car with:

The first 200km city driven with very little stop and go.
1 really slow 2 hour commute which usually takes 40-50 minutes A couple really slow hour plus commutes in the rain A little driving in Toronto downtown Use the a/c a little on one commute

I very, very rarely go over 100km/h and try to accelerate at a slow moderate rate, but this is still amazing to me. I only hope the car we get next week does as well.

I do try to shift into 3 or lower to coast to stops whenever possible, but I feel the gains here are very small on an automatic transmission. I also pumped the tires to 40psi to try and increase FE a little. I don't want to go much more than that as the tempreture can fluctuate greatly on the highway from 17 to 37 degrees from day to day and you can easily get a 10 degree fluctuation on a one way drive.

thx for that info.

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.

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.

[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.

[Thotprawsis]

Well here are my numbers so far. In the city I'm avg' 34mpg and on the highway I'm getting 43mpg. I'm just under 3000. I'm going in for my first oil change. I hope to gain a little more.

Change that oil to a good synthetic and enjoy even better mileage (albeit slight).

[Nigal]

I got my Dragon short ram intake put on last night so I'm interested to see if it makes a difference in mileage. It's going to be hard to keep my foot out of the gas.

[marcus]

41.-41.5 MPG last tank..

[uncleyaris]

my last fill, showed 46.9mpg. Damn I love this car. Gonna drive real grandma and aim for 50 mpg, lol

[slvryaris]

Yaris now has almost 32,000 miles on it and still getting 36-40mpg

[black2yaris]

I did the TRD cold air induction on mine & right off got way more miles out of a tank ,plus way more pop off the line . With the reuseable / cleanable airfilter & added fuel savings it's gonna pay for it's self real soon
