Guys at parts counter thought BMW coolant was no different than other coolants, then fat man walked behind counter (from new car sales?) and said other coolants can kill water pumps in no time. He said they had all kinds of problems with other coolants, even in GM and Ford cars using the "Dexton" (can't remember name) coolant from GM stealers.

I thought the guy might be bullsh*tting, but I bought the BMW coolant. It was $17.90 per gallon. I figure German chemists have always been pretty good, and you don't change coolant too often, and radiators and water pumps are expensive.

Anybody know the real data on this?
