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

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

This is normal. Mazda master tech. I work on these everyday. Every oil change they need to be topped off. The coolant evaporates from the bottle pretty quick.

Pros: coolant evaporates quickly

Vehicle: Mazda 3
