Okla Panhandle | Just finishing up an overhaul on Big Cam IV/435 HP, wanting to know what you guys think I should use for break-in oil? I normally run Cenex 15-40 synthetic, but was thinking I should use straight 30 weight conventional. And then how long should break-in be run? One more thought, truck will be farm use only( mostly 5-15 mile runs), so should I make a long run first day just to warm it up and break it in? Thanks in Advance! | |
