Hi Guys,

I just got a 2008 Cayenne S and I'm doing an oil change soon

I know factory recommends Mobil 1 0w40 but it's not REQUIRED right?

I'm thinking of using LubroMoly Super Synthetic 0w40, anyone have any idea if that's okay? (something about A40 spec?)

Thanks

correct. the factory recommends 0w40 but it's not required. but 0w40 is good for all temperatures. Plus it might not even be that great for lubricating and protecting the engine to prevent problems. my guess they suggest that to meet their MPG numbers.

still many cayennes running 0w40 continue to run well.

now for other grades you can use, lets start with where you live 0 works better in cold weather

Thanks for the reply!

I'm still running 0W40 since it gets quite cold here, but just wondering if make of the oil matters. I'm thinking changing to LiquiMoly (or LubroMoly w/e it's called) instead of using Mobil 1. So just wondering if it is up to A40 spec.

Here is a list of porsche approved oils.

My inclination would be to stick with one of the A40 compliant 5W40 oils. Oil temps on mine run no less than 200F in winter, 220F in summer, 230F when towing. I'd be afraid that 0W40 might run too thin at the higher temps. The other consideration is environmental. Non-A40 (or C30) oils may not be optimally formulated for the respective Cayenne exhaust systems.
