Mine costs like $35 for 89 octane and I get like 18 miles per gallon, but I can't keep my foot of the gas! The pipes sound to good to not let them be heard!
i wait til the gas light comes on. my camaro costs about 35-40 to fill but ill get nearly 300 miles to a tank...its cheap...my truck...god help my soul is over 50 bucks...and thats with regular...and i only get 260-280 miles per tank with that. a tank of gas in the truck lasts about 8-10 days.
