I heard this from a member.. saw it at walmart for $19.97 a gallon.. is it the SAME exact stuff. The ratings on the back of the jug are different from the standard Mobil 1 but I forgot what exactly to look for.. I thought diesel was a CH or CF rating and I don't think I saw it.

The PO changed the oil at the FSS interval on my E300 all it's life with synthetic.. somewhere between 10,000 and 15,000 miles. I'm coming up on 9,000 and getting nervous.. FSS says there is still 2,500 miles to go.
