Eurol brake fluid dot-4 silicone

Brake Fluid DOT 4 Silicone Fits: > 06-21 Softail; 06-17 Dyna; 05-21 Touring; 07-21 XL

 

While a vehicle that uses DOT 3 may also use DOT 4 or 5.1 if the elastomers in the system accept the borate compounds that raise the boiling point,
DOT 4, like DOT 3 and DOT 5.1, is a polyglycol ether-based fluid (contrasted with DOT 5 which is silicone-based).
Additionally, these polyglycol ether based fluids cannot be mixed with DOT 5.0, which is silicone based.

As of 2006, most cars produced in the U.S. use DOT 4 brake fluid.
