Why do you say were/was with regard to M1 ESP? Is it being discontinued?
Yes, it is now GTL based and does not look as good as before.
It does have Mb229.52 (just slight more stringent than .51 when it comes to oxidation, but not as LL04 in that aspect).
Someone mentioned VW504.00/507.00. That spec. is best from wear stand point, but not as good when it comes to deposits and oxidation as MB229.51/52 or LL04. That is why one should always go for oils that meet all those specifications.
