Antifreeze OEM Mazda or OEM BMW
I’m running 110k miles in my M40 X3. There was a coolant issue but other than that it’s been an excellent engine.
Pros: excellent engine
Cons: coolant issue
Vehicle:
BMW X3
Mileage: 177027 km
As you can see, straight from the jug, the Mazda coolant is resisting both corrosion and freezing better than the Motomaster.
Pros: resisting corrosion and freezing
Vehicle:
Mazda
I'd say to change out the coolant, and transmission fluid. DO NOT GET A TRANSMISSION FLUSH!!! Just get a place to change out the transmission filter, and top off the transmission fluid.
Cons: DO NOT FLUSH
Vehicle:
Mazda 6
I use BMW coolant cause it's similar in price, so why not. Actuall,y a little cheaper cause my dealer does discounts
Pros: similar price, dealer discounts
Vehicle:
BMW
Yes I had low coolant in my brand new CX-30 and had to top it off 2-3 times with the FL22 fluid (factory OEM). I think some air is left in the system that gets out over time. Since then no issue with the coolant level
Pros: no issue since
Cons: low coolant initially
Vehicle:
Mazda
Mileage: 94000 km
Part number: FL 22
I had my AC condenser replaced and looked at it in the parking lot and confirmed it was full of coolant, drove home, and it was low. I ordered and added some OEM coolant at home. It's been fine ever since
Pros: fine ever since
Cons: coolant was low
Vehicle:
Mazda
Mileage: 57900 km
By “air intake reservoir tank”, I assume you mean it’s the coolant tank for the water-air charge cooler. We need to know what car to tell if the coolant is suitable. That “G30” on the front is the important bit.

They called her back again to say after they started working on it, it's not the water pump, but a coolant leak at the cylinder head, at the head gasket, so what was originally a water pump, is now a head gasket job, 3-4 days.
Cons: coolant leak
Vehicle:
Volkswagen
Mileage: 14000 km
330i, coolant repairs.
Cons: coolant repairs
Vehicle:
BMW
So you don't mix coolants. BMW coolant uses embedded teflon or something. Dump in the wrong coolant and you have to run (I kid you not) laundry detergent through the entire system several times, flush the shit out of it several times then replace every single rubber hose.
Cons: wrong coolant bad
Vehicle:
BMW
