I plan on switching my brake fluid this weekend to Valvoline Synthetic Brake Fluid. It is exceeds Dot 3 and 4, and has a boiling point over 500 degrees F. Does anyone know of any problems that could occur? The car has over 100k.

It's OK I run that..
Just don't use DOT 5 [silicone base..]

 

I switched to the synthetic and also replaced my lines with a set of Earls. The brakes feel a lot firmer now.
