German Castrol (GC) is working great. But I think I'm going to switch to Schaeffer's oil. Higher anti-wear and better detergents, plus it's MB approved.

I'm hoping that in 5-8 years one of these wagons will be off-lease and in my hands . . .

Currently running Mobi1 5w-40 European formula. Also will be switching to Schaeffers.
