Mobil 1 and a Fram filter. I use this combination in all my cars. Never had any problems with either. I have the miles to prove it.
The MSP needs full synthetic, not a blend or conventional oil. It comes from the factory with synthetic oil. If cost is a concern, go to WalMart and get their brand on full synthetic, its about $8.00 cheaper than a 5 gallon container of Mobil 1. ( its probably knock off Mobil 1)
With a new long block costing roughly $3400, its not wise to skimp and go the blend route.
