Got 33.28mpg on my last highway only trip on the 3sgte with minimal boosting (passing and joining highway only). This is the highest for me so far.

I broke 400 miles on one tank once. but that was straight interstate w/ cruise on.

good post

Usually I get about 29-30 mpg with a lot of highway driving...

Last tank of gas I got about 23-24 mpg, b/c of: new 17's installed, four wheels + tires inside the car, and A/C blasting most of the time.

There are a number of things listed in the other posts that you can do to improve gas mileage. Good luck!

I brake 400 on a tank regularly, combined highway/crappy congested commute/street. No CC on (too much stop and go). I put gas in earlier this week w/430 miles on the odometer.

EPA milage are suppose to be off by about 7MPG on either end. This is to account for everything else in life such as type of gas used (certain mixture for different parts of the country), terrain (flat vs hilly), atmospheric pressure (more or less oxygen), etc. If you ever look at a posting for a new car EPA figures...it will give you a range in smaller print then the big numbers placed onthe window sticker. The big numbers like 22/34 is the avearge. So in reality, you might be getting 20/40. Everybody is from different places...and everybody's car is different maintience level. Just keep your car tuned and perfected and you will have close to the EPA results. Hope that helps clear up a few things.

cruise ctrl in the highway while drafting running @ 68 MPH, i get over 30+mpg in a GT. its slow but saves fuel.

Tell me the numbers you worked out your MPG with mate! I did a 400mile run the other day in the gt4 and averaged 30mpg my best ever recorded mpg, and thats with holes in the exhaust (where there shouldnt be)

Wow some of you guys get some awesome mileage on the celica, the furthest I've driven on a full tank is 310 miles. so about 23mpg with half city and highway.

after reading and trying these things iv saved alot...i never fill up and is always half a tank and never below a quarter......but i went 95 miles on just a quarter tank when i put gas in it was like ~3.7 gal
