Antifreeze PEAK or Prestone

Prestone European coolant...premixed

No issues.for.me

Prestone coolant. That's extremely good.

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.

Prestone teal colored euro coolant has never failed me.

I use the purple peak G13 in mine - from autozone. Its actually more pinkish when it pours. Made sure to flush with distilled water before adding the new coolant just in case but its been fine in my car. Don’t overthink it!

I use the Prestone 50/50 Prediluted coolant which states “guaranteed for all vehicles American/Asian/European” on the label. It is yellow/green. Zero issues because it matches the specs in the manual.

I use the orange dexcool stuff found at most auto parts stores. I think it's prestone, but I don't remember

Prestone destroyed my passats Cooling system, everything just deteriorated, the hoses in my car started to break up. I don't recommend prestone
