My understanding from my VW Dealer Parts Dept ..
some 1 1/2 yr ago is that their Red 'mixes with all types of coolant.'

It might even say that on the bottle.
and since there are now about  half a dozen different types of coolant 
in use , it's not hard to find coolants that claim 'mixes with all types 
of coolant. "

I like Zerex Long Life coolant too.

At the dealership where I last bought VW coolant, when I stated that I wanted coolant for a 1991 Volkswagen Vanagon GL Campmobile (though I had bought coolant and a few other things from them before), the first reply was that no parts for that vehicle were available, but maybe coolant was.  The clerk then consulted a computer, left for the stock room, and returned with two gallons of red coolant.  When I pointed out the error, he stated that that was the only coolant for VWs extant, that none other was manufactured, and that it was correct for Vanagons.  I demured, and asked if someone else might have better information.  Eventually, after an extended discussion that bordered on heated, he brought forth a manager, who listened, said, "just a moment," went to the stock room, and returned with two bottles of blue coolant.  He hadn't consulted a computer.
