We have a 2012 Mazda 3 and a 2014 CX-5. We are going to have the Antifreeze changed and I heard Zerex Asian Blue was an equivalent. Has anybody tried it? Is it safe and / or as good as the Mazda FL22? Here's what the Valvoline (makers of Zerex) sent me:

"The Zerex Asian Blue coolant is formulated to meet or exceed the Mazda FL22 coolant specification and is fully compatible with the factory Mazda coolant."
