I wouldn't listen to Porsche's recommendation on oil type and change interval...they, after all, are the ones that have looked the other way when it comes to the M96 engine issues. Jake Raby, Charles Navarro and JFP see these cars everyday and their troubles; best to listen to their recommendation.

FWIW, I change my oil annually (2500-3000 miles) and have been using Castrol Syntec 10W40. No clatter on start-up and filter/sump have been clean.
