Yeah, I haven't filled washer fluid in probably 10 years, but this weekend my Audi gave me an alert saying it was empty, so I figured as long as I was doing it myself I might as well see what the experts are using.
I think I've decided to go ahead with 1Z Einszett Kristall Klar. I have a couple of questions though for anyone who uses it:
The Autogeek inx. say to: Squeeze bottle to fill top reservoir with concentrate. Pour concentrate into empty windshield washer tank and fill remainder of tank with 1 gallon (128 oz) of water.
The bottle says to: take one part washer fluid (fill top reservoir which is 1 oz), mix it with 100 parts water (so that would be 100 oz), and then add it to the washer tank.
So I have 2 questions:
1. What is the correct dilution? Do I use 1 capful of product and 1 gallon of water (128 ounces), or 1 capful of product and just 100 ounces of water (or are 128 and 100 so close it doesn't matter)?
2. Do I mix it first (i.e. put the capful of product in a gallon jug of water, mix it a bit, then put in washer tank) or put the capful in empty washer tank and then add water to tank?
Thanks!
