I used it in my MB for the first three years of ownership. First FDS, then moved on to VST 5w-40. I liked them both very much, got great fuel economy and kept the engine spotless as far as I could see into the valve cover.
When the price went through the roof, I could no longer make the argument to choose it over Mobil1 Euro 0w-40.
