POAT vs IAT coolant: Engine-specific application and differences

[X15]

SOA868V9210 "Long Life Coolant" is a green dyed first generation PHOAT using Sodium Benzoate

SOA868V9270 "Long Life Super Coolant" was a blue dyed second generation PHOAT using Sebacic Acid and made by CCI Illinois in the US.

SOA868V9272 "Long Life Super Coolant" has now replaced SOA868V9270, it's made by Prestone and may have 2EHA.

How do you tell if its a HOAT or a PHOAT. This is the Nissan Green. It doesn't mention phosphate anywhere, but it doesn't say its not either. Blue is the same

Phosphates and silicates aren't considered hazardous material, therefore will not be listed on an MSDS sheet.

Zerex Asian Formula is a first gen Sodium Benzoate PHOAT, all the colors have the same chemistry, only the dye is different.

Honda Type II LLC is a second gen blue dyed Sebacic Acid PHOAT made by CCI, the Nissan Blue LLC is as well, those two are probably the closest you can get, if not the same as the old SOA868V9270.
