Last Fall, I bought a gallon jug of Pentofrost A2 antifreeze at Advance Auto for my FC. Haven't done the change yet, but after a long search this antifreeze was one of the few that's compatible with Mazda cars.

Red and blue Zerex Asian are the same .
Why would you not go with Mazda FL-22 or Ford Specialty Green? These are the proper coolants for your car, and recommended by Mazda for the rotary. 100% compatibility without question. The Ford is actually cheaper/more economical than buying Zerex as that is pre-dilluted, requiring you to buy two containers.

Just noticed Zerex Asian is only 50/50
The coolants dont have 2EHA from the ingredients.
Pentofrost A2 is an antifreeze concentrate for Asian vehicle applications in water-cooled engines. It contains phosphates and organic salts to protect all materials used in cooling systems.
Ingredients: ethylene glycol, 2,2'-oxybisethanol, sodium hydroxide
Pentofrost A2 is also on on Rockauto as compatible to 91 rx7
NAPA Green Concentrate Antifreeze & Coolant
Peak Global Concentrate
On bob the oil guy, they claim this is also a good alternative but Ford Specialty is better.
It meets the ethyl glycol base requirement of Mazda, and has NO silicates nor borates (and it doesn't contain 2-EHA, either)
ingredients: ethylene glyco,diethylene glyco, denatonium benzoate, water
Ford Specialty green- I was not able to find the ingredients but i read an article claiming it resembles Mazda Fl-22.
Quote from RallyWays
"Ford Motorcraft Specialty Green Engine Coolant – VC-10-A Premixed, VC-10-A2 Concentrate – The consensus seems to be that this Ford Motorcraft coolant is exactly the same as the Mazda FL22 coolant. In fact, people that have bought it claim there is often a sticker with the Ford part number covering the old Mazda part number 77508E20 – Note, it’s the same as the Mazda FL22 part number above without all the zeros and dashes. I wouldn’t hesitate using the Ford Specialty Green coolant as I do believe it’s exactly the same fluid that Mazda uses. Supposedly, the Ford coolant can be had for cheaper than the Mazda branded stuff.'
Would any of these be fine seeing that they dont have 2EHA?

I decided to go with Beck/Arnley AntiFreeze after reading this https://www.rx8club.com/series-i-tec...licone-238638/
Gives alot of info on AF without 2-EHA
Anyone using this Antifreeze?
Beck/Arnley Engine Coolant/Antifreeze Part # 252-1001U (available at places like O'Reilly's, on Amazon and others). It's referred to as a concentrated green coolant that's actually listed as an OEM coolant for Mazda vehicles. I got mine from PepBoys for $22 bucks with a coupon.

December 2021 update:
Just returned from local Ford dealer and informed that Specialty Green has been discontinued and superseded by Ford Yellow, being backwards compatible…for those of us avoiding 2-EHA this is not true.

both Mazda coolants are still available,
the FL-22 part number 0000-77-508F-20, it would have been the same as the old Ford stuff, same engine same car
the regular non diluted Mazda green coolant, which is similar to what the car had from the factory is 0000-77-501E-02
as a side note there are only 2-3 coolant factories in the US, so all of this stuff comes from the same place. you tell them the specs you want, color, bottle color, label art etc, and they cook you up a batch

I know you decided on Beck Arnley, but to answer the original question the only difference in the Zerex Asian formulations is the color. As you've discovered most here recommend the Mazda FL-22 or the now discontinued Ford Specialty Green. I agree but also feel the Zerex Asian would be a better choice than any of the Dexcool clones containing 2-EHA.
