He also swears by the Triple-Diamond stuff from Mitsubishi.
Unlike Hawk's mine didn't come with any ratios or indications beyond -70c, and the boys in parts had no idea of any other kind of VW wiper fluid (summer or otherwise) and had NFI about how to fill it up, and recommended 250mL per wiper tank - but they were basing that on where the indicators were on the bottle. Given this thread has been dead for some time, anyone else get ideas or updates on how they went?
1:4, 1 cap, 250mL - "until it foams too much" etc
