Use any brand of antifreeze you want. I have used Prestone in Mercedes for 34 years, and never had any problems. This week I will be replacing the third radiator in 9 months in the 126 chassis Mercedes. Guess what? All three had the Mercedes Glysantin G05 antifreeze in the cooling system. Coincidence? Maybe. Use the antifreeze that 80% of American motorist use. If it causes damage to your engine, you can sue Honeywell(the owner of Prestone), or wait a while and sue General Electric. They are trying to buy Honeywell.
What is it about Mercedes that they require a 'different' antifreeze?
Bill Lewallen Lexington,Ky. The Bluegrass State; but the grass is really green, and so is our antifreeze.
We are also the home of Valvolene the maker of the Mercedes coolant Glysantin G05.
