Antifreeze for Mazda
Mazda is named directly on Valvoline's official data sheet, and it is one of the four names printed on the front of the bottle. Mazda's factory FL22 is green, and the green version is made for exactly that system.
Mazda's factory FL22 is green, so here we recommend the green version. Now both the colour and the chemistry match.

Skyactiv engines and high compression
Skyactiv-G engines run an unusually high compression ratio for petrol. Higher compression means more heat in the combustion chamber and more thermal load on the aluminium head, precisely the zone the ASTM D4340 test examines.
In that test Zerex Asian Green returned 0.1 mg/cm²/week against a limit of 1.0, a tenth of the permitted loss.
An honest note on colour
We used to sell the blue for a Mazda and said plainly that the colour would not match. Now that we carry the green version, a Mazda takes the green and the colour stays the way it left the factory.
One thing does not change: FL22 and our product are two different fluids and must not be mixed. The correct approach is a complete flush and refill rather than topping up the old fluid.
