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.

Sounds like good information. Why did you choose Castol other than the approval? Have you ever used Redline? It gets high ratings from the members here.

Mobil1 is not longer 100% true synethic oil. Stay away.

Keep the Mobil 1...I'm running Royal Purple 5W40.

Yes, this is a controversial topic, but I've read Charles Navarro and Jake Raby's comments and that's good enough for me.

Where are you getting Royal Purple 5W40? at a FLAPS?
what price you paying?

thanks

Yep PL, it is a hot topic on a lot of boards. Saw a Jake Raby posting on another board (maybe Boxsterspec?) that he won't make oil recommendation because of the ensuing fireworks.

I'm going to use an approved oil, but not sure which. Just in case I ever have to try to negotiate an IED engine deal with Porsche.
