I suspect that the MB coolant offers better corrosion protection. It's all I've ever used.

My point deals with the belief that MB coolant is "cooler" than anyone else's. I've read countless posts here that suggest this to be true.

People who believe this are likely sending "what I want for Christmas" letters to St. Nick every December.

No ones coolant "cools" any better. It's the proportion of water to coolant that affects heat transfer.
