First what oil recommendation? It's still under warranty so I am thinking it has to have the Chrysler oil requirement? I was hoping to stick with Valvoline. I am new to dodge I was a Ford man. Can you give me any information on the Hemi? It would be greatly appreciated.
go to ram forum and learn weaknesses on the hemi, mainly cans and lifters and see what guys are doing for lubrication. It's a bunch of who shot John to suggest the mds requires 20 weight oil, half the forum uses 5w30 w/o any issues. Those cams are starved at idle, keep warm idle to a minimum, maybe tune up idle with a tuner. 8 speed is a mixed bad, great to have the engine in good rpm's most of the gears, but they preheat the fluid and to een check the fluid is a two week process, slightly joken but not by much. Hemi's are probably the highest wear engines out there, look at the uoa's. Pennzoil is very poplular, PUP 0w40 is being added into the mds engines for the extra moly. you may want to do a uoa to see how your hemi is doing, but you may want to wait til 30k miles.
