As I perused the Walmart oil aisle today the following was found, "European Formula" Mobil 1 lists Mercedes, Porsche,Audi and VW as all approving of this oil, I thought Bavaria was in Europe?lol.

Mobil 1 reformulated 0W40 a few years ago. It has not bothered to pay BMW to certify it. The previous version was BMW approved. I run the new version in my turbocharged built motor 1999 E36 M3, my stock 2008 E61 535xi and my modified 2008 E90 M3. No worries on my part.

You'd think the SAE classification would be the thing to check on, no need for 4 auto brands on the container,along with"European" formula!,lol, its all marketing hype, they also have extended interval and high mileage oils, I couldn't sleep with 0 weigh oil in a FI motor, but I'm old school STP era minded, lol.

I think late model Porsche 911 Turbos use 0W40. So does the GT3 that revs to about 9000. Oils have improved. Thick oils get to where they need to be later on cold starts, increasing engine wear.

If you have a worn out engine, a thicker oil might reduce oil consumption. I use the 0W40 even in my all forged fully built 700 rwhp turbo E36M3. The 2618 alloy pistons specify a looser clearance, but the 0W40 has been no problem.

But as long as the car is under warranty I would suggest running the exact oil specification, in a nut shell the addtive packages and anit wear ingredients have been reduced. My 1996 r1100gs can not use any of the newer oils. BMW issued a bulliten about using the wrong oils in my engine because of the lack of zinc and such.
