Antifreeze PEAK or Prestone

I use Prestone teal European car formula. No problems yet

50/50 Peak blue. Everyone says BMW brand but not everyone has a bmw dealership near them nor what’s to pay out the ass for coolant. I’ve had BMW’s for 23 years and they run perfectly in many ways. All I ever used was Peak 50/50 Blue

OE BMW coolant should be your first choice, and if it can’t be, second would be another reputable coolant maker that offers a European vehicle variant. For example, Prestone makes a blue in color variant formulated for use in euro cars. I’ve used both, never had an issue with either.

Replace the orange stuff with new Prestone orange stuff.

Been using Peak Final Charge Global in everything. 2004 f150, 2018 ktm 300, 2015 ktm 1290, Yamaha FJR....top offs / mix complete changes with flush. No issues with any.

For coolant - cheap Prestone (concentrate) got my old Speed3 to 60 000km no problem. I used 25% glycol and 75% distilled water and a couple caps of redline water wetter. No more overheating, even idling in +35°C.

I used the pre-diluted Peak European Vehicle formula. It is Hybrid Organic Acid Tech HOAT which is the same as the Genuine BMW brand.

Blue antifreeze that says European only. Your local autoparts store usually has PEAK Euro full strength or Pentofrost NF (G11) antifreeze. Either one of those is good, just dilute it 50/50 with water.

I prefer peak brand 50/50 premixed. The pink or red Asian import coolant is the only thing I would ever put in my toyota or Scion. It's the same stuff that comes in them from the factory with hybrid organic acid technology (HOAT). Coolant not only keeps your car from freezing in the winter, it has corrosion inhibitors to keep your engine healthy.

In a pinch I added Prestone Universal green to my VW coolant, next day the expansion tank had a nasty looking brown mixture in it that freaked me out, my desire to put inexpensive universal fluid to top off my B6 ended up costing me over $150 for VW to drain, flush with cleaner and refill with G12+.
