I decided to start this topic rather than hijack the Selenia oils topic!
Anyway, i have always wondered about using fully synthetic oil, but have always just let the garage put the Alfa recommended stuff in.
My next service is coming up and i would like to try fully synthetic oil(Mobil 1 etc), but i've heard good and bad reports on it.
Does anyone know exactly why fully synthetic is supposedly better. What are the benefits over normal multigrade oil? My V6 has got 65,000 miles on the clock, and i heard somewhere that synthetic oil is better used in newer engines (if 65,000 miles is considered old). Is this true?
Any recommendations would be gratefully recieved.
