Hi All,
I have a 997.1 C4S that's done ~62k miles and I'm curious to know what the best oil grade is that I should be using?
The car's still covered by Porsche warranty and is being serviced at my local OPC, hence choices are limited to 0W40 and 5W40 based on what's in the manual and the approved oil list I've been sent by Porsche.
The folks at the OPC only use 0W40 and were a bit surprised that I'd think of putting anything else in the car, hence the question.
The internet (being the cacophony of voices that it can sometimes be) seems to suggest that if I use anything anything other than 10W50 (as apparently recommended by Hartech) my engine is sure to explode/get scored bores, but also that if I use 5W40 there's more wear at lower temperatures as the engine's warming up, although other specialists (Paragon Porsche, Revolution Porsche and Precision Porsche to name the ones I found online) seem to recommend 5W40.
Any ideas?
Cheers
