Well, I could say that MB coolant is ph balanced for aluminum motors. (It is.)
I could say that most of the mechanics here in Chicago, say to use MB coolant. (They do.)
I could say that many Ferrari owners use it as well as do Porsche owners. (They do.)
I could say that it contains other ingredients to help with wear and tear on water pump parts. (If heard that as well.)
However, my best advice is to use MB coolant because so many knowledgeble people on this forum will say the same thing. It's just cheap insurance vs. taking a risk with an expensive motor.
