Filled the Yaris up this morning and was pleased to break into the 4's... 4.9l/100km which is about 48mpg for the tank.
Quite a difference from the 6.5/l100km or 36mpg I was averaging before I found this site.
Thanks for all the great info

That's awesome, Frink - congrats!

Don't forget to enter your car's EPA "combined" value in the garage so people can see how much better than the rating you're getting.

BTW - how much different are the EPA vs NRCAN ratings for your car? Are they as wacky as mine? EPA: 49 mpg (US) hwy vs. NRCAN: 55 mpg (US) hwy

perdiction 34-35mpg

A bit higher 35.95

I can't wait for that 26.9 tank to fall off my 90 day average. Then I will be close to top 10 above epa (I need 39mpg average). It has been a goal of mine for the past few weeks.

The NRCAN works out to 42.7 US mpg vs the EPA rating of 40mpg hwy.
I cant find a combined rating for the Yaris, is it just an average of the two?

The time I got 50mpg in my car I did do some drafting (but not too close).

Not a close in draft, but just close enough to drop the air speed. Two to three car lengths I would guess. Not close enough to give me white knuckles. The other part of the equation is warm temps. 85F makes a big difference.

Good question. I looked at http://www.fueleconomy.gov, and of course there's no 06 Yaris listed (though the 07's must be identical). It's a mystery.

Maybe have a look at a couple of cars' EPA ratings here that DO have the combined value (like mine) and you can probably figure out the formula from that. I don't think it's a straight average. One side is weighted more.

EDIT: interesting about the higher CDN highway ratings, yes?

Yes, I guess it has to do with differences in their testing proceedures as opposed to any climate variables or differences in CDN and US cars that would affect the FE rating, 'cuz I'm pretty sure the Yarii are all the same.
Which brings up another question.
The 15" tires on my Yaris RS have a larger diameter than the base model's 14 inchers, it works out to a 3.4% difference.
Now I wonder if Toyota has taken this into account with the speedo and odo readings and adjusted them accordingly.
Hmmm...

Do you have a GPS to verify yours?

If not: Using Google Earth to verify your odometer accuracy

A friend at work has a handheld GPS, I'm going to use that to calibrate the Scangauge next week.
Found the formula for EPA Combined mileage:

The MPG as published by the Federal Environmental Protection Agency (EPA) in the 2006 Model Year Fuel Economy Guide.
The combined EPA MPG will be based on a combination of 55% city driving and 45% highway driving.
The formula to determine the combined MPG rating is as follows:
EPA MPG Combined = 1/(0.55/MPGCity + 0.45/MPGHighway)

Darn! I hate getting into the thread so late...makes me think it won't get read. Anyway...I'm so excited. I'm very proud to say that on my 500 mile trip from Virginia Beach to Hilton Head, Sout Carolina yesterday I obtained 58.65 MPG!! This was truly 100% highway mileage. NO city whatsoever. I'm sure what helped the most here was my cheating strategey of 60PSI in the tires and an average speed of 58 MPH. Yeah, 58...anyone want to talk about putting a bullet in your head? "Real" HF owners can probably translate this to 64 MPH. But since I have the shorter 5th gear (49state?) transmission, I get 55 MPH @ 2250 RPM. Damn! Anyone got the gears I want for sale?? Once I get that taller gearset & taller (& lighter) wheel/tire combination...IT's ON!!....like Donkey Kong! Well, as least the fruits of my hard 500-mile-at-58MPH labor are an astounding 58.65 MPG...not some lousy "just breaking 47" achievement. -Almost makes my agony worthwhile.
