I want to change the coolant on my 89 K100. I have a jug of Super Tech prediluted 50/50 antifreeze/coolant. Says on the label it is compatible with any antifreeze. Any car with aluminum and other engine metals. I used Zerex G-05 previously (recommended by a friend). Any opinions? The Super Tech is left over from my KLR coolant change which is not too picky from the fluids it uses. Thanks Ken in Katy.
