celltechkpw -> What grade oil 4 towing 5th wheel camper (7/12/2006 3:38:12 PM)
|
I have a 2002 2500 hd 6liter gas, with auto, and want to go the synthetic oil route. I like the Pennzoil platinum and was wondering if the 5w-30 full synthetic is the way to go for RV towing 10,000 pounds in the hills of Ohio and Kentucky, no mountains here. is that the correct grade? Is the change interval longer? thanks Kevin Cincinnati Ohio
