- Dry Boiling Point = 230° C (446° F)
- Wet Boiling Point = 155° C (311° F)
- Low viscosity
This is the Genuine BMW DOT4 brake fluid in the Low viscosity formula as used in most 2004+ BMW models (see below for specific model information). This is the same brake fluid used from the factory and is compatible with the latest ABS and DSC systems. Low viscosity fluid works better in the tiny channels in the DSC system. Previous Normal viscosity fluid does not flow as easily which results in a delayed response from the ABS/DSC system and a spongy or mushy brake pedal during a panic ABS stop. This is especially worse in colder climates where the fluid is slow to reach operating temperature. Since this is a safety concern, it's vital that you have the correct fluid in your car.Normal or Low Viscosity?
For the track it's always Normal Viscosity brake fluid. This is because Low viscosity fluids will be too thin once exposed to typical track temperatures. For regular road and street use, however, you should use whichever fluid came from the factory. The cutoff between Normal and Low is not by model year. If your chassis existed before 2004 it uses Normal viscosity (all chassis up to E53). But if the chassis was introduced after 2003 it will use Low viscosity fluid (all new chassis starting with E60). The lone exception is the E53 X5 which could take either: 1999-2003 X5 uses Normal; 2004-2006 X5 uses Low.
