Is Walmart Super Tech coolant the same as FL22?

The jug states that it is OEM for Mazda, and that it is SPOAT. It should be fine, right?

Not an expert on coolants, but isn't the spec PHOAT for Mazda or was that a typo? I wouldn't mix the OEM with anything but PHOAT like Zerex Asian that you can get at O'Reilly's. Is it dark green?

Zerex Asian OET is what you need. AutoZone sells the concentrate for like $24 a gallon. Add $1 for a gallon of DISTILLED water from the grocery store, and you're in business.

Just keep in mind that Mazda mixes their FL22 55/45, not 50/50, for enhanced corrosion protection ever since the TSB on the heater core issue.

Why not just use the Mazda coolant? I paid $26 for a gallon at my local dealer, and I have the reassurance that it's the exact right formulation. It lasts so long anyway, I'm not worried about saving a couple of dollars.

Do you know when Mazda switched the coolant? I had the newer coolant put into my 2016 last year but I'm trying to figure out if my 2019 has the old or new coolant.

I believe it was April 2019 that the newer coolant was implemented on the assembly line. The attached TSB says CX-5s with VIN ending in 605884 or lower are affected and have the 50/50 FL22.
