Brake Fluid

Hey guys,

Wanted to ask if a specific brake fluid is required for E46 M3.

I see most people go with the ATE Super Blue or Gold. From my understanding, as long as the fluid is a DOT4, it should be acceptable.

Not trying to run cheap fluid but is it really necessary to run the ATE?

When I first bought the car I was unaware of how specific the oil must be and just wanted ask around if it applies to the brake fluid as well?

Quality DOT 4 fluid is all the E46 M3 requires. ATE Super Blue and TYP200 are popular because of their raised boiling points, and going from Blue to 200 you get a clear change in colors when you refresh the system, helping insure a proper flush.

Personally I run Motul RBF 600 in my cars, it's another quality fluid with a very high boiling point.

Now if you're going to track your M3 I highly suggestion going to a fluid with an elevated boiling point over standard DOT 4 fluids, this will help prevent against boiling brake fluid at the track.

Right on! Good to know. I mean it is basically just a hydraulic fluid in a sealed system. Main concern was the seals if another "brand" was used.
