Not long before I traded it I took my "d" to my local dealer for an oil topoff.The kid sent out to do it had regular synthetic in his hand...not LL-04.When I pointed that out he thanked me and went to get the correct oil.Yikes!
Also,the pdf makes reference to only one brand of LL-04 oil.There are many,as I suspect most of us know,and at least a few are easily available in this country....Mobil 1 ESP Formula being just one.Not long ago I managed to get 20 litres of Fuchs synthetic that's LL-04 and 229.51 (Mercedes diesels) approved.I got it for just over $7/litre including shipping.
