Yes, I have heard that Zerex G-05 is excellent for MB.

My car was slightly low on coolant, enough to make the warning light come on when I was up steep hills. Dealer said I could use Prestone yellow. I bought it at Walmart for $9.00 and only needed very little to bring the coolant level up to par.

On the bottle, it also says its safe for any make, any model, any year and can be mixed safely with any color anti-freeze without damaging your cars engine/cooling system.
