Note that it's not even SN and it's aimed at MB, having only MB approvals and ACEA C2, C3. I'm sure it's a great oil, but in a more "vanilla" application, I don't see a lot of ROI. XOM won't guarantee this for 10,000 miles on a vehicle calling for ordinary ILSAC oils. If someone wants a thick 30 or even a 40, I can think of several different more cost effective options right within the XOM songbook.
