Default Re: 5.7 versus 4.7 fuel economy
i've got a '08 5.7 with 8k miles and im getting 13mpg on average (and seems to be dropping). im hearing a lot of talk with people getting around 16-17mpg. i dont do a lot of highway driving, and live in the northeast (getting colder and colder). is this my problem? or is everyone fluffing there true mileage?
