Joe,

Check out these articles relating to Rotella, which is a CJ-4/SM rated oil and uses a reduced ash formulation with less anti wear additives (mainly Zinc and Phosphorous) and see how other Porsche owners have fared using this oil.

JTP -

Those oil arguments you linked too have been raging for a few years on just about every car forum that has flat tappet lifters in their core engines or in older engines commonly used by the membership. AFAIK, our boxsters use rollers. Correct me if I'm wrong.

Thanks!

Joe
