Ok, so I got my most recent 'Busa from a guy that just recently did an oil change. The oil was changed about 1000 miles ago *roughly*. I just sent him a text about 30mins ago, asking what oil he used (for reference, so I can use the same stuff). He tells me he used Castrol Syntec 10/40 Full Synthetic CAR OIL. Now in all my experience, I've always been told that's a HUGE no-no..
My questions for the experts are....
1. What should I do about it?
2. Should I or should I not use a full synthetic in the 'Busa (was told not to)
3. Should I be worried about 1000 or so miles running this?
Please no negative comments, I didn't know, and I sure as hell wouldn't have done this myself.
Thank you all.
