Just visited the site which maybe doesn't give the answers most of us would expect from Morris Lubricants! However from what I briefly saw, the site doesn't even list the VW T2. Nearest alternative is a T1 1303 where it suggests, for engine oil, a call to the technical helpline - maybe even they don't want to get into this debate! For a VW 1500 (type 3) they actually suggest Multivis CST SS 10W-40! Like I said, maybe not what a lot of might expect from Morris?
