Hello,
Another UOA for you. An extended drain of M1 0w-40. it was installed at the dealer as a free change, so I cannot comment on the specs/age of it, though I assume it was new stock as of February 2006 when I did the previous change.
I did this one with 15400 miles on the oil, 32283 miles on the car. The car has been great, giving me well over 30 MPG, and being used more or less exclusively for 35 mile trips and longer, driven VERY gently. I changed the oil more or less at 0%, as it was the winter and tough to do.
I refilled with Amsoil SSO. Ill sample that one when the computer tells me it is at 50%. I have a large stock of schaeffer's 5w-40 that is good for MB 228.31 and .51 (low SAPS, long drain) and VW 502 and 505, FWIW. Ill likely keep the SSO to about 10% though...
Anyway, here is the latest (far left) as well as the older ones going to the right:
