A lot of Boxster owners complain about start up noise (I do not have that problem). One of the reasons I stayed with the 5W instead of 0 is due to my belief that the thicker oil at start up may be adhering to the engine parts better. Just a thought.

From what I could gather reading previous posts JFP in PA works at a shop that keeps track of the oil changes and the results of the oil analysis after the change.

I'm sure JFP gets tired of repeating himself so much, why not search what he has posted on this & many other topics.
JFP recommends Castrol Edge 5w-40 (formerly known as Syntec)
Due to JFP & LN this was my oil choice until Jake Raby introduced DT-40 by Joe Gibbs. Ironically DT-40 only comes in 5w-40.
