It can happen, but not sure how probable it is on the N62... Doing it insitu saves alot of dealer money. You won't have a ton of say in the matter when its a warranty job.

Anyone measuring their oil consumption rate? I'm making some mean smokescreens with my X during extended idling times. My engine has 112,000 km on it, absolutely ridiculous.

I'm running it harder from time to time when its all warmed up on on/off ramps to burn off any buildup on the exhaust side but not really banking on that for anything.

Anyone had issues with this clogging up the cats?

Any success with changing oil viscosities?
