just achieved 41 mpg (us) on my latest tank, almost entirely highway driving, probably an average speed of 110 km/h.

something i just realized about this tank of gas was that it was premium 91 octane fuel, this is the first time i have used it and only did so because the station was almost out of gas and were offering premium at the same price as regular.

i was really surprised by getting 41 mpg because i made no real attempts at keeping my speed down and for big stretches of this trip i was probably going 120 km/h. before i crunched the numbers, i expected about 37 mpg.

i think i might try to fill up with 91 again and see how good it is around town.

i'll report back to my fellow fuel economy nerds.

as i said before , cars that were made for 89 fuel dont burn the higher octane fully, therefore you kinda wasting your money and polluting. mind you your car will be awsome to drive , more pep it might even drop in revs, but all in all you wasting your moolah

well, i'm not sure i was wasting my money because the 91 was the same price as the 89, and it seems that my fuel economy was quite a bit better with the 91,
whether that's true and whether the added cost of the 91 would balance out the fuel savings, i'm not sure.

i know that there has been a lot of debate as to whether better fe is achieved with higher octane gas, and based on this one tank it seems to me like that might be the case,
so i'm going to waste about 3 bucks to conduct an experiment on another tank of 91.

Comment: Mpg on the rise since a few tanks ago. Can be due to summer weather or my increased application of practical fuel saving techniques since the car was returned to me (NB: car has been driven by my brother for a while).

I haven't been too wrapped up checking my mileage, but so far during the first 2k of driving my Yaris, I've been very pleased. This fill up:

425.9 Miles
10.813 US Gal
39.388 MPG

Beats the crap out of the 15 mpg (barely) I got out of the Dodge Dakota I traded. Now I can afford to drive to work. Still don't wanna, but that's another problem I'm trying to solve in a similar manner.

I fueled up this morning. 379.5 miles on 7.516 gallons = 50.492 US MPG

wow... that's about 21.316 km/L...

very great Fuel Efficiency!!!!

N9QGS · 07-12-2007, 11:46 PM

I have the 2007 US model Yaris S with the 1.5, and I have gotten between 36 and 39 on most round the city some highway, on strict highway trips with one person I can get 42 to 43 mpg US. Im very please never gotten below 36 yet have over 29,700 miles.

slvryaris · 07-13-2007, 05:03 AM

Same here 30,000 miles and nothing below 36 mpg. Maybe if I could drop some weight it would increase

stuffy · 07-13-2007, 11:48 AM

this chart has the lifetime fuel economy for my yaris, which is mostly city driven,
the low dips in the chart correspond with the winter time.

lifetime fuel economy of 33.4 mpg

90 day running average of 34.11 mpg.

marcus · 07-13-2007, 01:42 PM

men that looks pretty bad...i always thought our yaris average is beyond or atleast 40 m/gal.. even with city driving...what am i missing here???

stuffy · 07-13-2007, 02:03 PM

well, my fuel economy is not the best, but you have to remember that most of my driving is short city trips.
this is the least ideal situation for fuel economy, especially in the winter when the engine runs cold and never has a chance to really warm up.

i could make some changes for improved fuel economy, but i'm just not super-obsessed with it and on occasion i like to run through the gears a bit more quickly than the average hyper-miler.

i think my numbers are in line with the revised american fuel economy numbers for the yaris.

also, i share this car with my wife and she doesn't know what hyper-miling is. :0

marcus · 07-13-2007, 02:13 PM

nah its all good as long as i get 500 km on a tank im happy..

We have our second 50+ MPG member! Congratulations!

petesimac · 07-15-2007, 12:02 AM

Roadrunner, could you describe exactly what type of driving you're doing; are you hypermiling; how fast do you drive? Your numbers look suspiciously high. Why do you fill up after only a couple of hundred miles sometimes? Why, when you did 50% highway, was your mileage worse? How are you figuring your mileage? Just curious; not accusing you of anything. It's just that on a recent trip with my 5sp, going 60-65 mph the whole time on 99% highway, the best I could get was 46.5%, which was great, in my opinion. I just find it hard to believe that on a car that promises 34 mpg city, you are getting in the upper 40s to 50 mpg.

stuffy · 07-15-2007, 12:48 AM

i also find your numbers a bit hard to believe roadrunner, especially when most of it seems to be city driving.
