[urq] Audi antifreeze, peak or prestone?

[steven j]

I hardly drive the 83 urq but from my records 30 months ago I must have drained out 2 quarts and put in 2 quarts of new mixed 50% with distilled water.    Antifreeze that is available locally is PEAK or Prestone.   I did purchase some antifreeze from Volvo for a Volvo, or maybe Audi sells a few types of antifreeze by now.   I certainly don't mind spending an extra $20 for the best.   What should i put into my WX engine?   I also have a 100hp WE powered coupe.
