I personally think that it is good to know how some of the rivals of the Yaris perform. The Civic is a very strong rival but its fuel economy is not as good as that of the Yaris. Even the Fit is slightly behind the Yaris when it comes to F.E.

Yes! Yes! Yes!!! I had a trip to Columbus, Oh this weekend from MD, and on the return tank of gas I averaged 43.16 MPG!! I did mostly 65-70mph and 95% highway with no special techniques. Man was I happy. I have been averaging about 33-34 since my third tank of gas, with a high of 37 mpg once. And I thought I would never hit 40.... man I love this car! :)

[flagmunkey]

got about 38 this time around. i inflated my tires and used lucas. im gonna try inflating more. im also gettin used to engine braking. learning how to use that more efficiently..

[bigdoglover]

last tank i got just under 35 mpg-mixed driving but i seemed to be stuck in construction traffic a lot on that tank.

I average between 35-38mpg. When I started out it was like 32 then broken in I was averaging 37-38 but now I take the freeway to work(while running late) and am averaging about 34-35.

I got the most mileage I had since I got new tires in June. When I got them my mileage went down. Not bad but certainly not as good. Today I managed 47mpg. Not my best but certainly better than 37mpg or 33mpg. yeah my standards are high when you hit 50mpg more than once

Of course the warm weather helps

Mohawk/Husky uses approx 10% Ethanol in BC.

While E10 certainly dings your mileage it's not the end of the world. I've pulled several 50+ MPG tanks and my liftback has never seen straight gasoline. Both Nevada and California (the only 2 States I've fueled up in so far) are E10 year round and E10 RFG (reformulated gasoline) in the Winter.

i noticed that regular driving city full tank will get me about 580-590 km compare that to hwy drove to go fishing on one full tank 90 % hwy. its about 640-660 km assuming that last bar is 50km travel. my gain for driving on hwy is about 50km more... kinna odd where my old celica city wise is about 350 km and full hwy 550 km...thats 200 km difference..wow big difference..same driving habits. i even gunned my celica up to 180 km/hr at that camp trip; still got over 500 km on full tank.

I agree, I just had my worst FE by far on a tank and it's because I was going 120km/h with the A/C trying to stay ahead of the insane long weekend traffic using e10 gas. We avoided the traffic, but I got 5.889 l/100km over that 448kms of Highway driving.

Currently in Canada the Yaris Sedan Auto is rated at 5.6, so you have to definately drive outside of the bounds to not get the epa.

True, I have tried Mohawk in my former car. Didn't give me good fuel economy and starting took a couple of seconds more to crank (may be for my car only). Otherwise not too different from the regular stuff. When I said "we still have" (Post #1591), I meant we could still find.

[Goalie]

First tank full, made it 377 miles till the last blip started blinking 37.26 MPG. 5 speed with AC on the entire time.

Sweeeeeeeeet

[swidd]

I got 43.63MPG on todays fill-up, tires at 41PSI, driving 65mph 80% highway. Was stuck in traffic a few times. Turns off engine at red lights most of the time.

[BailOut]

I've set a new personal record. I fueled up this morning with 8.453 gallons after 444.1 miles for 52.538 MPG.

[marcus]

ok i got 620 km and filled up to 38.5 liter of gas =16.1km/liter. 45.5m/gal, 6.2liter/100 km.

One thing I've noticed using the SGII and different driving styles and road conditions:

The ECU seems to adjust/tune the performance to the style and conditions of driving over a period of time...for example, if I go from Providence to Boston and back on a warm summer day, and do 70 to 80 MPH, my gas mileage will be in the low 40's that day.....then the next day, same weather, same route, if I semi-hypermile the FE will only be a little better - mid/high 40's....but the following day it'll be back up to 52 - 55 MPG. I've noticed this about a dozen times this summer. The same thing seems to happen when and after rainy weather impacts the FE. The conditions of the previous trip seem to affect the FE performance of the current trip. Could it be that for many drivers, the capability of realizing this really high gas mileage with the Yaris is never noticed because it takes a couple of days of conservative driving under good conditions before it happens?

No significant change to driving conditions except wife drives more than I do. See Post # 1523 and also: http://www.gassavers.org/garage/viewgaslog/264. Also, we have encountered a lot of road works which created traffic jams. We always drive for maximum safety and comfort but do not waste fuel unnecessarily. In essence, we drive the Yaris like it is a family car and in that sense, the fuel economy numbers should not be too different from those of a typical common Yaris user.
Results have become quite consistent. Fuel calculator used:.http://oee.nrcan.gc.ca/transportatio...ut.cfm?attr=16.
Easy to use. Just copy the result and paste it to the post. Uses up some space though. Fortunately there seems to be no shortage of space here.

I agree. I do not have a scangauge on my Yaris but I do have something like a trip computer on my other car with which I also get better than EPA fuel economy: http://www.gassavers.org/garage/viewgaslog/266?. I do share your observations. I have been suspecting that I might have been too subjective but now I am more inclined to think that the ECU remembers things.
