gas millage poll please...

I get usually 25.5-27mpg on a stock 99 GSX with over 205K on it. Mostly going 75-85mph.

Work trip yesterday, 310 miles (14 gal. tank is in the 2g's I believe) doing 78-87 mph most of the way with a bit stop & go due to contruction, traffic, & lights.

I get excited when I get over 210 per tank while acting a ass & boosting frequently. I do notice a drastic decrease in mpg when boosting hard. But 5 lbs doesn't seem to affect much when city driving jumping from light to light.

Depends on a lot though. I drive an automatic & i try to stay in 2nd gear when city driving under 40 mph.

MPG depends on Boost Leaks, driving habbits, & what condition your o2 sensors are as well. I bet with a great economy tune, we could get a record high for mpg's for DSM's.

200 miles to a tank is more common than you might think. I was getting about that until I really started to tune my car. And by that I mean.. really started to learn how to tune my car...

I actually keep track of my gas mileage with every tank. Here's how my driving usually pans out.
I have three things working against my gas mileage - AWD, turbo, and automatic transmission.

Highway avg. - 27mpg
City avg. - 18mpg
Daily avg. - 23mpg

Highway tree hugger - 35mpg
Lead foot city driver - 12mpg

1/4 pass - <2mpg

A tank usually lasts me 310 miles if I run it until the light comes on and takes 13.5 gallons when I fill it. I've rolled it past 400 miles on a few occasions.


My sister used to have a GS. She would get about 38mpg daily driving.

I'm getting 25-30 mpg with bad wheel bearings, a bad rear differential, bad alignment, pre-turbo exhaust leak, unplugged O2 sensor, and some crazy phantom knock.

How many of you guys that get 30+ mpg are running at least 8.5:1 compression? I find that my 1gs get about 30% less mpg than my 2g did. This is with both 1g cars running stock 7.8:1 compression.

I am looking at dropping a set of EVO 9 pistons on 1g rods into my motor if I cant find a stroker block and crank on a junkyard around here. I have allready searched for 2.0T blocks with no luck.

9:1 here. Increased mileage on the 2g could be other factors too like aerodynamics and OBD2 tuning.
