OAT Extended Life Coolant lasts longer, No Silicate to drop out of the coolant....So you don't have to Flush the sediment out when it comes time to change it.
IAT = Inorganic Additive Technology......Silicate (Large amounts) is the primary corrosion inhibiter & is a better faster acting additive, But VERY short lived because of the Silicate dropping out of suspension over time. Conventional Green Coolant.
OAT = Organic Acid Technology......Silicate Free, Organic Acids take place of Silicate as the primary corrosion inhibitor.
Dexcool & other OAT coolants.
HOAT = Hybrid Organic Acid Technology......Small amounts of Silicate(Hybrid) & Organic Acid to control corrosion.
Zerex G-05 Yellow coolant. There are some G-05 HOAT coolants that are orange, John Deere G-05 is green.
