Antifreeze Pentosin or OEM Honda

Nothin better than that OEM Honda

I’ve used Pentosin Pentofrost NF, it’s the same as OEM

Use pentosin

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

I’ve never ever seen OEM Honda coolant even remotely dirty, sludged or have insufficient protection even after 100k miles.

I've always used the Pentosin equivalent in all my Volkswagens and Audis. Pentosin E/SF. Pentosin SF is G12 (pink) -2005, Pentosin E is G13 (violet) 2006 onwards. Safe to mix with factory fill, of course can always go to the dealer for coolant too. These are concentrate, so you do have to mix 50/50 with distilled water though

If it's inconvenient to go to the dealer, you can buy the correct coolant at NAPA, they carry Pentosin brand chemicals.

I had a bunch of Audi G11 kicking around from my Audi 100 that I used to have. Made by Pentosin, same smurf piss BMW used.

Put it in my e90 when I did the water pump.

Pentosin has good equivalents.

For Coolant OEM Honda the blue stuff is perfect it's almost like it's made for the car.
