exactly what oil to use? 503.01, 502, 505 or 187?
I read the very informative list of oils on the FAQ, but I think I got confused. I bought castrol syntec 0-30 euro formula that is vw 503.01 approved.
Is that the correct weight and rating? Or is it for the new TT?
Thanks,
Alex
Bob Quindazzi recommends the 5W30. He built my bottom end.
