if you want to go the cheaper option, semi synthetic is also fine.
You NEED to state which Mobil1 you are using. Is it the silver 5w-50 or the gold 5w/10w-30?


What is the viscosity of the penzoil you are looking at? Ideally, you want one of the viscosities below, going thicker as your car gets older.

0w-30
5w-30
10w-30
0w-40
5w-40
10w-40
