I think Mobil 1 5W-50, or Rally Formula, was the first M-1 sold here in Europe. Especially in Finland it has a legendary reputation to be the best all around oil. Nowadays it has lost most of it's glory thanks to the ester-fan-boys discrediting the polymer content of 5w-50 and fast viscosity loss.
If you take a look at M-1's in Russia you also find M-1 10W-60 "Extended Life" and M-1 X1 5W-30, which is M-1 5W-30 rebrand in USA.
