For some of the really low miles reported, like 12-15, are you guys going by the trip computer or calculating it as you fill up? I'd bet you're getting better mileage than that (as long as you're not hammering it all the time), just do the math next time on fillup.

 

i calculated it yesterday just before i filled up and got 11.78 mpg. 145 miles and 12.3 gallons used. Like I said I hit a stop sign or red light just about every block or every 3 blocks. Also I go to school during rush hour so I sit in a lot of stop and go traffic. New York city is terrible

 

11s, 12s, maybe 13s. Supercharged and in the city.

 

21.5 All hi-way and three red-lights.

 

23.1 most of the time.

 

18.3 mpg, 50/50 highway/city, hammer down every chance I get.

 

With 7692 octane I average around 19, with Chevron92 octane I average around 21. A friend of mine told me he switched gas stations and had similar results, he has a different car and the stations are different. I have heard of others having the same thing go on, I guess some cars prefer the taste of a certain gas lol

 

22.9 in the city with LOTS of stop and go. I haven't taken it out on the highway yet. I've done the math as well as use the info on the dash and it's about the same. According to the info, it says I average 25 mpg.

 

on 15.5 gallons.. i only got 198 miles on my trip odometer.. i usually shift at 2500rpm for each gear

 

~16 mpg. Very few highway miles. Mostly city and country roads for pleasure.
