Re: gas mileage

My 1990 454/400 Crew Cab gets 4.5-5.5 miles per gallon. I think. I don't know my odometer is accurate due to my speedo being sketchy. And I know that it's off due to my 33ish inch tall tires. Wheels and tires are ridiculously heavy, and that takes it's toll on mpg. Truck is pretty much a winter vehicle. I don't have a long drive to work (6-7 miles) so it barely gets to operating temp. **** sucks, but it is what it is and mine is waiting to get Cummins swapped...
