I am the new owner of a 2002 575M Maranello. Reading through the owners manual it says to use Shell oil. In my other past and present cars - including a '57 chevy and a C5 Corvette - I have used Mobil 1 synthetic oil. I am inclined to do the same in the Ferrari when it comes time for an oil change. Do any owners or technicians have any experience with using synthetic oil?
