Not that I'm an expert given the amount of trouble I have with my truck, but a few things that have seemed to help my mileage on a 1997 Sierra is working it hard when it's hot. Cleans the engine out I think. Best I've ever gotten with the Vortec engine(305)is about 22 mpg(imp. gal.) and that was just short trips. I'm sure if the engine would work that way on a road trip it would get 25mpg. ALso find that higher tire pressure helps. I have 235/85/16 (load range E) on the truck and try to keep the pressure around 50-60 psi. For the sake of mileage 235/85/16 are better than 265/75/16. It should have less rolling resistance with the same circumference(actually slightly bigger). If you want good mileage a 6.2 diesel would work with a bunch of work.(only if you seriously need mileage) I put Bosch dual tip platinum plugs in the truck and it did nothing. They likely needed changing anyways though. It doesn't exactly pay to do mileage mods.
