I'm trying to make sense of this coolant issue, and I see some gaps in the logic. If Mercedes coolant is so superior to other coolants, why isn't hasn't the general public (i.e., the "synthetic oil-using crowd") picked up on this fact and spread the word about using it for all vehicles? I'm a materials engineer, and I see nothing special about the materials used in the Mercedes engine and cooling system when compared with other vehicles, nor do I see anything different on the demands the cooling system makes on the coolant. The same benefit Mercedes coolant gives for its vehicles should also benefit other vehicles.

Why hasn't there been any advice issued on using Mercedes coolant for ALL vehicles? Wouldn't this also be "cheap insurance"?
