GC should do great in your car. Please do post a UOA when you get it as we need more data points on this engine. I think we will see a few Biosyn UOAs on this engine in the near future as more people are trying that.
I'm currently trying redline 5W40, primarily due to its HTHS of 4.6 and its high P and Zinc levels. Hopefully these factors should help with fuel dilution, intake valve deposits from the pcv system (POE cleaning ability), and reduced wear on the fuel pump cam follower. I'll post the UOA when I get it.
