It all comes down to how often you want to crawl under your truck and driving conditions. If you wanna do 3000 mile changes, you could probably go with Wal Mart's Supertech. Staying with dino, lots of guys around here love Havoline. If synthetic Amsoil or M1 would probably work well. Driving conditions and your engine are really your only clues to what oil is best, and a Used Oil Analysis is the only way to tell how your engine likes an oil. Your engine may love the cheap stuff, and not do any better on a high $ synthetic. I would say, pick a good dino, have it analyzed and go from there.
