Originally posted by CB2: Ok, so I'm trying to decide on a new oil for my 2001.5 170 hp chipped VW 1.8T. Oil analysis with Valvoline SynPower 5W40 showed insolubles just a bit too high.
quote:I think some 1.8T owners who practice extended drains are concerned about M1 0w-40's tendency to thin down to almost 30wt and thicken back up to near 40wt. If you're adhering with the 5k drains, M1 0w-40, 5w-30 are fine, but I would stay with one that has 40wt because you're running higher boost. In fact, the oil you're using right now is excellent too.

Mobil 1, 0W-40 comes as a factory fill in all Porsche Turbo cars...
