So how do they get away with labeling stuff as 'mixes with anything.'? I don't recall ever adding anything to the Journey before except maybe water. But I have definitly put that universal stuff in the Magnum. Probably be changing that in the next week now that know about it :BangHead:

They get away with it until they get sued.

GM was using OAT coolant (Dex-Cool) and a lot of cars were wrecked when owners mixed the regular "green stuff" with the OAT coolant. It turns out they reacted with each other and caused the pressure caps on the system to stick open causing over heating and low coolant levels that wrecked engines by creating hot spots from low coolant. Interestingly, Prestone came out clean in the law suits because their coolant did actually mix with the OAT coolant in their tests and no one knew about the long term reactivity. GM took it in the teeth for not warning owners not to do it.
