Antifreeze Pentosin or Prestone

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.

Replace the orange stuff with new Prestone orange stuff.

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.

Pentosin has good equivalents.

Prestone European Vehicles Antifreeze & Coolant states, Superior guaranteed protection - 5 years / 150,000 miles. Prestone Platinum All Vehicles Antifreeze & Coolant states, Extreme protection - 15+ years / 350,000 miles.

Drain/refill every two years for me, Pentosin coolant only!

I personally use Pentosin SF for GM cars,it's not the cheapest,but it is one of the best. Made in Germany. Similar to Dex-cool but pink,no problems.

CRP the USA distributor for Pentosin; discusses, service intervals with the various long life VW coolants (g12, 13, etc): in their line Pentofrost SF, E, etc @ 14:00: Pentosin - Antifreeze Looks like Pentofrost E; the latest G13 equivalent is recommended for your car with crp's application guide; mixed @ 50/50 with deionized water

If you are going to use Prestone brand, then you'd want Violet color.

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+.
