Whats the skinny on this "new" version of 5w50? I've been using Mobil 15w50 for years in my old BMW and would like something a touch thinner.
The Mobile website says it still carries Porsche A40 approval, ACEA A3/B3 A3/B4, MB 229.1/229.3, blah blah.
Its probably GTL like the new M1 0w40 FS, but is it the same formula? Same add packs? Is it just a thicker 0w40 FS? It seems to have the ZDDP content as 0w40, and just a touch less than the 15w50. And whats up with the "x2"?
