    Ate Super Blue Racing DOT 4 "low-viscosity"?

    I'm getting ready to attempt a brake fluid change on my 2003 530. My Bently manual says to use "DOT 4 brake fluid" for cars manufactured up to 9/1998 and "DOT 4 low viscosity brake fluid" for cars manufactured 9/1998 and later.

    I purchased the Ate Super Blue Racing DOT 4 fluid from Bav auto. Does anyone know if this qualifies as a "DOT 4 low viscosity brake fluid"?

    I called BAV auto to ask and the salesman said he didn't know anything about a "DOT 4 low viscosity brake fluid". He recommended the standard Ate Super Blue Racing (or the yellow).

    Any advice on this issue is appreciated. Thanks.

    I autocross and track my car and rely on the Ate Super Blue/Gold for my brakes... I have never had a problem with boiling the fluid... assuming you aren't doing these activities - you may be best served by the Pentosin fluids... they should be less expensive than others out there...

    Guess I'll get the low-viscosity brake fluid

    Thanks for the input. Seems that a lot of guys are ignoring the low-viscosity recommendation given in my Bently manual and are running ATE Super Blue Racing instead of a product like the ATE SL.6.

    Interestingly, ATE posts a change interval of up to 3 years for ATE Super Blue Racing and only up to 2 years for SL.6.

    I am using my car only for a daily driver. I have no intention of taking it to the track.

    But based on the advice given here, I should probably get a couple of cans of the SL.6 (or equiv.) and follow the Bentley recommendation. Anyone disagree?

    I'm sure either fluid will work fine during normal operating conditions. It's that 0.00001% situation where the ABS is doing it's thing. The question we can not answer is what would the thicker fluid do. Why did BMW spec out the thinner stuff? Is it better performance at low temperature? Or is it due to the higher cycling frequencies of the Mk20/60 systems? Without good information, the only thing you can conscientiously do is follow the recommendations.
