AMSOIL recently released two formulations of high performance brake fluid:
AMSOIL Series 500 High Performance DOT 3 Brake Fluid AMSOIL Series 600 DOT 4 Racing Brake Fluid
AMSOIL Series 500 High-Performance DOT 3 Brake Fluid has a dry ERBP of 274°C (525°F) and wet ERBP of 156°C (313°F). AMSOIL Series 600 DOT 4 Racing Brake Fluid has a dry ERBP of 304°C (580°F) and wet ERBP of 210°C (410°F).
DOT 3 fluid is required for the vast majority of passenger/truck owner's manuals. The DOT 4 fluid is suitable for those, such as myself, who use their cars on the track and aren't worried about complying with owner's manual requirements.
