As I am approaching 6k miles on my new Subaru Outback 3.6R my thoughts turn to what to use on th4 OCI ; synthetic or conventional?
The owner's manual states either can be used - my main thought is whether the engine has had enough 'break-in' time to switch over.?
I'm going to keep it simple here - Pennzoil platinum or CYB is the choice; what say you educated oil gurus?
