Just want to know if Pentosin DOT 4 LV brake fluid is good enough for a 2006, 325xi , I'm about to make a purchase between Pentosin, Castrol GT-LMA, or Ate, any assistance would be appreciated.

I've used it, but felt the pedal got soft quicker than I expected, and changed to ATE Typ 200 when I replaced the front brakes.

I have 6 mths on the ATE, but I feel no degradation, and based on experience with it on my E46, should hold up better for 2 yrs.

Brake fluid is brake fluid. If it meets DOT 4 spec then it will work as good as any for the two-year period it will be in the system. I have Pentosin in my car right now. I flushed the brakes in May of this year. It works as it should.
