Thanks for the replys. Is Castrol syntec 10W 40 porsche approved? My car has about 6 months of warranty left and I do not want to void out the warranty. I would not hesitate to use 10W 40 if my car was not under warranty. I also plan to drive my car during he winter. Will 10W 40 be sufficient for winter driving as well as summer?
