I doubt you'll notice much of anything, you won't have any problems either making the change. AD

When you said "dyno" oil in the title, I actually thought you were running this thing on a dynamometer or something. I think you actually meant the common nickname for conventional oil, "dino", short for dinosaur.

I took a second look myself. Either way I don't see any problems, and doubt you'll see much gain or loss especially in the warmer weather that's on its way.

Well I think you would have to dyno your truck before and after switching to dino to actually know for sure.
