Guys lets not get into a discussion about oil. (lots of opinions) I hate Mobil Water, It was also when I still build Subaru race and rally cars the recommended by Subaru its kak (********************) we lost bearings at an alarming rate, changed to Castrol and Valvoline blend 5-w40 and 10-w40 life was good. But to get back to the comment below ( but you should not be running 10W-40. Either 0W-40 or 5W-40) if you read your Boxster owners manual in page 108 it states 10w-40 and 5w-40 and nothing about 0-W40. It states use Synthetic or a blend but never straight Dino oil. So no Mobil water for me, but you go a head and use it.
