On a reasonably level road I can get 22-23 mpg. But on the loop I take to work I get anywhere from 18-20 mpg driving super conservatively. But I think with 3.92's I would be using less throttle. I had a ranger with 3.73's pulling 33's I put in 4.10 and I gained 5 mpg. Even though my rpms were higher I was using less throttle. I know there 2 different trucks but I think the same theory applies.
