I am due to change the coolant in my 2018 Mazda3, I went to the dealer to get few jugs or coolant, but the parts guy showed up with Zerex Asian Blue coolant. I asked for the oem stuff, and he says that the Zerex stuff is all they use.

The OEM is 55/45% diluted ratio compared to the Zerex 50/50%. Although, both meet ASTM D3306.

I assume it should be totally fine with Zerex, but I dont want to risk anything with the advice from the dealership to save a few bucks. Apparently, they don't even have OEM stuff in stock.

Any of you have used Zerex blue without problem?

Thanks!

I used Zerex blue in my Honda engine for well over 5 years without any complaints. After this period, the coolant tested at .24 volts on my meter which meant that it still had some useful life left. Zerex/Valvoline is giving a conservative estimate with their drain interval guarantee, in my opinion.
 
From everything I’ve read the blue and green Asian coolants/antifreeze are the same. My 2018 Mazda has green so I went with the green Peak.

Been using Zerex Asian blue and Zerex Asian red for many years with no issues changing it every 5 years. It is good coolant from my experience .
 
Zerex Asian (regardless of color) is the same as Mazda FL22, which is also Motorcraft Specialty Green. It’s a PHOAT coolant. I always found it odd that Mazda wanted a 55/45 ratio. But the 50/50 mix will be fine.

If you buy the Zerex in pink, it results in a nice brown color when you mix it with the factory green!
 
I never actually checked the real color in the overflow tank, it looked blue ish, but maybe its green LOL. Have you used this Peak stuff a lot without problems?
I have only done one drain and fill with it. No issues.

I think Zerex has asian in blue and green, its confusing, whats the difference?
 
Four years ago I did the first drain and fill on our Mazda (then, 9 years old) using FL22 from the dealer.

Last year I repeated with Zerex Asian Green.

Times will tell.

EDIT: Regarding pink and red, I would suspect that to be geared towards Toyota - OAT with Sebecate.
 
I did my 2016 Mazda with the green last fall. We had temps down to 0ºF here this winter and all is well. I also did my Nissan with the blue and it's fine.
