Owner reviews for antifreeze

For my Subaru I use the Subaru Super Coolant.

Zerex G40 is pretty good. Made by Valvoline and has G12++ spec.

Prestone European coolant...premixed

No issues.for.me

Prestone coolant. That's extremely good.

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

I use peak 50/50 blue European with no issues

I used the Peak coolant that was pink, it's been a few weeks and no catastrophe so I think you are fine.

I run the prestone green coolant in my e36 since 2006 and my 540i/6 since 2008. They're both fine. The old engine still looked & ran great. The radiator in my 540i was still from 1998 until very recently when I did a cooling system refresh - entirely preventive.

I stopped having to wear gloves when we stopped using blaser coolant. That shit gave me blister covered rashy skin that was unbearable for 2 years. All went away as soon as we switched to a cheaper Castrol coolant. Works about the same too.

Bmw original coolant is the only way to go. I made the mistake of using shell coolant once and it froze, causing a hole in my radiator.
