I am considering buying one of these cars, but want to see what type of gas mileage people are getting first.

Please list your average MPG, driving habits, mods, and type of driving (highway mostly, city mostly, %)

I am sure I will enjoy this car, I just want to be sure I can afford to put gas in it.

 

average 23 in winter and 24-25 in summer.

Stock and spirited driving.

32 highway is acheivable .

 

in the upper 20 city and the 29-33 on the free way in the city getting on if once and a while, but recently just took it on a 400mile trip one way and got avg of 42 all the way there driving it like an old lady. and mine is an 09SS/tc with a tune, hardened charge pipes, intake, 3" downpipe, big intercooler, hardend mount upper/lower

 

I average 28 with normal driving on highway + city average with some spirited driving.

 

22.3 for my city and highway combined

 

I only have 1200 miles on the car but my average so far was like 18 :s I do drive it very hard though... I drive a lot for work so I'll keep a eye on a 250 mile trip next week.

 

27 in the city and about 31 on the highway. Never got the chance to go a long distance.

 

i average about 23. its more stop and go driving than highway tho. on my trips to school where its mostly highway with a few stops i'll get about 28. i do punch it every now and then too. and i got an intake and charge piping for now.

 

my dash is showing 29.3 right now. i have a long highway commute to work everyday. my SS/sc was slightly better on gas though. was usually around 33 on average

 

dont forget that premium is recomended and you will get worse gas millage with 87

 

i get 25-27 mpg usually unless i drive like an ass then im down to like 20

 

Thanks, I did know that it needs premium. My other car needs premium and methanol so it's okay if I need just premium.

I just want to know what I will average driving normal MOST of the time and like a psycho some of the time.

 

I am Trifecta tuned with a catless CIA downpipe. I get the same gas mileage with the mods as I did stock, providing I lay off the boost! All city driving, a tank of 93 octane will average me about 22-25. All Highway and I am right at 30. My usual commute, which is a mix of city and highway, I average about 27.

 

28.4 mpg according to the car. I never reset it either. Nearly 23K miles on it.

I can get 38-42 mpg on the highway with cruise set at 67ish if it's a nice day out.

 

31.5 by the Avg MPG display, calculated I get right around 30. 90% highway on a 40 mile commute to & from work. I can get 32 if I keep my foot out of it.

Trifecta tune, otherwise stock.

 

I get 32-34 average mostly highway with a few WOT pulls per day.

 

28mpg average with city/freeway mixed with spirited driving.

Hard driving will show about 24mpg in mainly city. I have seen as high as 34mpg so far on the highway.

 

I don't know how you guys are doing so well. I can get a MAX of 25 MPG on the highway. I drive 30 minutes to and from work everyday. The only way I can get 25 MPG is by easing into the trottle and keeping the RPM down around 2500 at the max. I also keep boost under 3 PSI if possible. It sucks. I can get 300 miles to my tank this way. If I'm driving it like I would like to, I get about 240 miles to my tank.

 

Are you stock?

 

Yes I am stock. My numbers seem to be way off. I really try to save on gas, It's just not working. When it was new, I could get close to 400 miles to a tank. Now I'm averaging around 295 if I'm very careful. I watch my MPG INST everyday. Any ideas?

 

I average about 28-31 on highway, about 24 in city. I don't baby it, but I also don't drive it like I stole it.

 

mid to high 20s

 

8.5L/100km driving it like its supposed to be driven

 

2500 miles on the car I get 34.5 on the interstate 27 city and 22 on saturday nights!
Veh is bone stock other than nitogen in the tires set at 34psi. 91 oct fuel from chevron.

 

Have you tried all the obvious stuff? Make sure tires are properly inflated? Use a handheld, accurate guage. I only use the cars TPS to watch for change, not the accuracy of the reading.

Dirty air filter?

Try different gas stations?
