Anyone have the part number?

Has anyone found a US source for this oil?

I will tell you guys, do a tech data comparison...unless you are just looking for extra viscosity, I am CONVINCED that GC (green or gold) is a better oil.

I have a guy running it in a newer 1.8t. I told him I'd pay for a UOA if he ran it 10k. Any BMW dealer has it. Not expensive, I believe.

A J, I will be interested to see how it turns out.

I haven't seen it at my BMW center. I'll ask the service manager next weekend at the BMW club event at the dealer.
