don't mean to throw a bomb on the party but I'm going to stop using Mobil 1 and start using Castrol Syntec 5w-40 which is on Porsche's approved list. M1 was changed recently and I've heard it doesn't provide enough protection for both chain and bearing wear. Its obviously a controversial topic but if you search Pelican and Rennlist you'll see at least one engine rebuilder who will not guarantee a rebuild if M1 is used at all or zero weights.
