ATE 200 is a great DOT 4 fluid but here's a warning. I have always used ATE 200 in my Porsches, but on my Macan ATE 200 the brake pedal squeaked a lot, which was actually coming from the master cylinder. Turns out this is a common problem when using ATE 200 in cars (or at least Porsches) that require a low viscosity (LV) fluid. So if you drive a newer Porsche or Audi I recommend sticking with an OEM branded fluid or Pentosin LV fluid. I will continue to use ATE 200 on my '10 911. When I washed the ATE 200 out of the Macan and replaced it with LV fluid (twice) the squeaking was gone.
