[QUOTE="lossscause, post: 125697, member: 1525"] What's your reasoning to switch to syn? Are you just looking for longer oil life? Our shop truck has 460k+ miles on it on Rotella 15W40 dino w/5k oil changes it's whole life and has never given us any problems. Same goes for the 4 other 7.3L's we have with 300k +. I think I might try switching to a lighter weight oil this winter to help with cold starts on my personal trucks. [/QUOTE]
