No. Green Prestone is not HOAT. Prestone may say it is safe to mix with any colour of antifreeze. "Safe" is not the same as "won't clog your radiator."
Sounds like Zerex G-05 HOAT would be OK, or the more expensive stuff at the dealer.
Propylene glycol coolant is actually pretty difficult to find.
I keep returning to the decision line I use. Should I spend $10 or $20 or even $30 more to prevent having to replace a $200 (part only) radiator? Why am I even asking myself this stoopid question?
