Is this a big enough issue that you'd recommend I drain and refill with thicker oil before next Spring?  :chicken: |
Chances are you will be all right, but if it was me and what I have read, yes I would do something. You may be fine, but why chance it. there were a "few" who brought up a possible link between "
aos" failure and 30 weight. Its about the viscosity and the posche engine breaking down 30 weight oils easily. An easy fix to save you some money is in the following thread. Just empty out a few quarts and replace with 50 weight.

"when i got my second boxster ppi'ed at a porsche mechanic he gave me the car a cocktail of mobil 5w30 and 15w50.... said it would give the grade of 10w40 which mobil 1 didn't have... so when i made a mistake of putting in 5w30 he said drain half the oil and add 15w50... did that and everything is good... when i had the 5w30 in (about 600 miles) i noticed frequently on start ups i would get a puff of smoke after the cocktail mix none at all and seem to drive a tad cooler and quieter.. funny though when i had my 97 i used 15w50 and it would puff smoke after 2-3 start ups..."
