Antifreeze Prestone or OEM Mazda

Prestone European Vehicles Antifreeze & Coolant states, Superior guaranteed protection - 5 years / 150,000 miles. Prestone Platinum All Vehicles Antifreeze & Coolant states, Extreme protection - 15+ years / 350,000 miles.

If you are going to use Prestone brand, then you'd want Violet color.

Last time I priced FL 22 at the Mazda dealer it was about the same as AutoZone I was surprised I thought it would be considerably more.

G12/13 has better lubricating properties over long periods of time, which is why they use it in what you always hear as "lifetime fill." This is due to the phosphates in the coolant.

The Prestone stuff works just fine and there shouldn't really be an issue.

I have been using Prestone Green FORever, in all my cars but the one that is Dexi-cool. I don't think I have ever had an issue with the Green as I flush my cars on a bi-yearly kinda thing or when I have to change things.

I use Prestone Celisus Anti-freeze/coolant. It's pretty much universal, never had a problem in my 92 TD or my 91 1.8 8V with coolant or overheating.

Volkswagen G12 coolant - ~$20/gallon Prestone Extended Life coolant - ~$8/gallon Distilled water (preferably reverse-osmosis/deionized water)

I've had zero issues using green prestone for the past 100k on my 16v. Just change it every 2-3 years. Car never has any white build-up or any build-up in the hoses, so there's no real reason to not use it. Ph level stays neutral. Engine even has the original water pump at 180k :laugh:

Do not use Prestone 50/50. It is technically compatible, but it is a different formulation. Using Prestone 50/50 will shorten your service intervals to 36,000 miles. Beyond 36,000 miles you will cause damage to occur to the seals.
