I only had the truck for a week, and I know the first day I had it I played with it just to see what the 5.7l had to offer, after realizing this was a lot of engine for me I started to drive it gingerly.
and the computer said I was averaging 14.
I think it rose to like 14.9 when I was on the highway, and that is the best I can recall, It might have needed a tune up, but it felt like it was running great to me so...
I am just one of many, I think you need to go out and do a few test drives.
