[QUOTE="CarportMechanic, post: 1484686, member: 18312"] I put in about 35 gallons when I fill up and average about 550 - 600 per tank. 35's with 3.73 gears for me. Ultimately you should be turning less RPM's when going 70 mph vs me. I dont see why your MPG would be that terrible. I know you most likely wont get 16 to 18 mpg but dont see why 13 to 15 couldn't be reasonable. Your currently getting about 5.7 MPG........ [/QUOTE]
