Oil Choices
I know that Porsche recommends Mobil 1 0W-40. Another synthetic, AMSOIL, purports to be BETTER than Mobil 1, citing several tests. http://www.tsadvancedsynthetics.com/
I don't have the technological expertise to understand what these tables, charts, etc really mean. Any engineers here who can say whether AMSOIL's claims are true?
