Re: oil changes
Update...I used Castrol syntec 10w30 on the latest oil change, part synthetic. Alot less valve train noise at cold start up with this. I do have the dreaded piston sleeve slap, but only at a warm start after the truck has set about 2 hours, at no other time. And then for only about 1 second. I drained out the Penzoil, never use that again! I have tried Mobil 1 before, but I think this Castrol is far superior. I use 10w30 instead of the 5w30 cause it never gets that cold here. My specific engine responds well to the Castrol. FYI
