I see Motorcraft AF part numbers numbers being used more often here now. I know it as Motorcraft Specialty Green, and it does come as a concentrate. However, though it's been awhile last time I priced it at a couple area Ford dealers it was ~$34 a gallon. I realize that it's a concentrate, but still pricey.

If you're referring to your 2016 Mazda 6, looks like it has a non pressurized recovery tank. Pep Boys OEM 'concentrate' would work for that. Do some distilled flushes till clear, then using your cooling system capacity, add half capacity (for 50/50) with AF and top with distilled. Can make a 50/50 premix for recovery tank after. In non pressurized tank system I've never not been able to get at least 50% AF into system and top with distilled.
Now if you're wanting to use FL22, after distilled flushes you've got to do d&f's with it until an AF tester shows correct concentration. Or, find the block drain(s) open them and then fill with AF. That's why with premixes many folks just do simple radiator d&fs on shorter intervals. You shouldn't need to worry about it for awhile though.
