Antifreeze Prestone or OEM Honda

I've only ever used Prestone which works great and has never been an issue.

I use prestones all weather,Great stuff

But for the love of god use the blue stuff. Preferably the correct brand but I couldn't find any in my hick-ass town so I used Prestone and I haven't noticed any ill effects

I have looked at the additive packages on all Honda compatible coolants. Many other manufacturers (Toyota, Ford, Hyundai, Mazda, Subaru) have switched to similar coolants that are slightly worse than Honda coolant. Honda has the strictest requirements for their engines that they refused to give their engines to GM for Saturn cars after GM said they will require GM coolant. Here are my rankings:

1) Honda Type 2 (OEM) Coolant Best OEM coolant Has about the same Diethylene Glycol and anti corrosion and detergent additives

After that, you can run generally whatever universal coolant you'd like. I do a universal Prestone and have no cooling problems. I live at the beach and drive my stage 2 Jetta 2.5L pretty hard.

I bought prestone Max concentrate for all vehicles. The yellow stuff. I also looked at the technical data sheets on the product. Happy to report this thing runs cooler than it ever has and I live in Phoenix arizona.

Prestone European coolant...premixed

No issues.for.me

Prestone coolant. That's extremely good.

Prestone does work, but Toyota uses RTV to seal the coolant passages between timing cover/thermostat housing and engine block. Prestone uses 2-EHA which has been shown to be aggressive on silicone, however it’s not uncommon to see leaks with the OE coolant that uses sebacic acid which is also a plasticizer. That said, I have a Sienna and LS430 that’s filled with Prestone, no coolant leaks… yet.

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.
