dexcool

Does anyone run dexcool in their engine.  GM has been using it exclusively in cars for almost a decade.  It is made specifically to cool high output, aluminum component enigines.  I was going to drain my coolant and make the switch to see how much of a difference it would make.

I have run Dexcool. Yes, You can leave it in for 5 years. BUT ...YOU MUST NOT leave it in longer. It just turns to sludge past the 5th year and clogs the radiator. It just breaks down. Did this in my van. ?
 Yes, it reduces wear on the water pumps. But I don't worry about the wear factor. Heck, we were all using green stuff when these bikes came out.
 There is no difference in cooling efficiency.
