I bought a traditional oil-filter end-type wrench at Autozone for my M104 / E320 filter. Fits and works great (with a 3/8" extension / ratchet).

Syn oil doesn't create leaks, might exploiit existing leaks more as regular oil thickens a good deal more when cold/parked.

I bought gallons of Mobil 1 Turbo Diesel & Truck (5W-40?) at Meijer last week for $16 regular price, a class IV synthetic that meets all S/gasoline requirements. Many of us with gasser Mercedes use this (as well as the diesel crowd) and it's popular with the VW/Audi crowd also. Good price.
