Seems to do better than my Benz which is right at 20mpg. I havnt hand calculated it but I would say 20-24. Not a powerful truck so theres never a reason to hot rod it.
This is number 4, I was going to play with this truck (lift, wheels, tires, etc) but I really dont need it and have found that I lack time for extra toys.
This will be sold and then the 7.3 here when I get a chance to fix acouple things.
