Organic additive technology coolant uses long life organic acid inhibitors instead of the silicates and phosphates in older green formulas, which is what lets it run a ten year service interval. It arrives already mixed at fifty percent with demineralized water, so it goes straight into the system with no measuring. Mixing OAT with a conventional or HOAT coolant drops the inhibitor package back to conventional life, so do not top off with anything else.
