I'm using the Prestone yellow-ish stuff and it seems okay. I could not find any of the undiluted green stuff around here, asked a friend who manages an O'Reilly's store and he said they usually had it but there was some sort of supply chain issue at the time I was buying it. I'm not certain there is much difference to be honest. The Prestone yellow said it was compatible with just about anything.
