Never seen a Ford gas last longer than a Chevy gas on the original engine. I use to work for a guy out in rosharon mowin pipeline right a ways and he had a 99 Chevy one ton with a small block 400 in it with 400,000+ miles on it still. starts right up everytime and durin summer pulls a gooseneck with a tractor on it everyday. You know what they chevys are like a rock
