Default 10 year coolant in ZJ

So could I run 10 year (purple) mopar coolant in my ZJ and XJ? I figured I'd ask to see if it's possible and if there are any benefits to this? Thanks!

I WOULD NOT run OAT (purple) in your ZJ or XJ because if you have THE SLIGHTEST BIT of any other coolant in the system, it will cause corrosion of any aluminum parts, like your radiator. It also reacts with silicone seals and softens them. You'd best stick with ethylene glycol (green) coolant. JMHO.

I understand mixing it would definitely cause harm. Thanks for the other info!
