Having been an Audi owner for the last 20 years and now an 986 S owner for 13days ... are any of you running 5w40 Castrol Syntec Edge Full Synthetic? Or do I need to fire sale on the TT forum?
My indie shop says "yes" ...perfectly fine to run Castrol ... while others say "no" 0w40 Mobil or 5w40 Motul!
I am in the Pacific Northwest. Incidentally I see Wallmart in Washington State has 0w40 Mobil Full Synthetic for $25 5qt!!
look forward to your oils of preference ...
cheers,
Brian
