Coolant runs through the cooling system in the engine. When someone makes statements that the green stuff works fine in a MB engine, they are ignoring what may be happening inside the cooling passages. I have read posts from MB shop owners , who have witnessed the corrosion effects of improper coolant.

I can't for the life of me understand why someone would risk their engine in order to save what MB Dealer antifreeze $20 bucks a gallon versus Green , make up a number $8 per gallon. So we are talking saving $12 dollars over 2 years equals $6.00 per year!

Use what the MB recommends or the equivalent G-05.
