I would consider it an OAT, a Dexclone, because of the 2-EHA inhibitor.

IT wouldnt matter to me because its basically Prestone no makes no models.
And I'm not a believer in universal coolants.

I call AMAM “beater coolant”-it goes in junk vehicles no one much cares about. Like my company Transit!

AMAM?

What type of vehicle are you putting it in ?

2005 Toyota Highlander. Just purchased. Previous owner had yellow coolant put in by long time Chevron repair shop.

If you find the SDS it will say.

Most of the mix with everything stuff is OAT.

Agreeing with a previous poster, universal "dex clone" OAT AF using 2eha. Those are the most common store branded universal AMM type AFs.

AMAM?

All-makes, all-models. Universal.

Aka ok for anything, good for nothing.

There are NOATs with 2-EHA. It was my impression that those are not compatible with OATs. Am I incorrect?

But I agree, the ST AMAM is probably a knockoff of Prestone AMAM...OAT with 2 EHA. In that case, it's dexcool without the royalties paid.

I'm fairly certain that's a generic AMAM OAT Dexclone coolant that would work fine in almost all vehicles if properly flushed of all old coolant. It would be fine to add to a GM or foreign vehicle that came with a Dexcool 2-EHA coolant for TOP UP but may cause issues in a vehicle that came with something else like G-05 for TOP UP (mixing different chemical make-ups).

I base this opinion on knowing many people who used AMAM Dexclones in Hondas, Toyotas, Mitsubishies etc...without issues after a full flush. I wouldn't use a Dexcool/Dexclone in any older vehicle made before seals/ gaskets were upgraded to those impervious to the 'plasticizer' affects of 2-EHA.

If in doubt, flush it. Then fill with either Toyota pink or Prestone and be done with it.

And Prestone coolants are fine, nothing wrong with them, provided you don’t fall for their marketing that they can be mixed with whatever coolant under the sun.
