When did you start putting in synthetic oil? (Castrol Edge Titanium)
My first service is around the corner and I've put in 3k km on her, I got 5 free oil changes from the dealer.
My whole family uses Castrol Edge Titanium so I think I'm going with that.
My friends says since I get free oil changes, just use up whatever the dealer gives me first + its bad to put in synthetic oil this early.
Is this true?
