I've done a lot of testing of brake fluids, and for street, or combination street and track, you can't beat this stuff. It doesn't absorb moisture as much as the high dollar stuff, it has a pretty high boiling point (high enough to hold up in my race car for two 30 minute road races), and it's cheap. Of course, if you just cruise your car, just go with a normal DOT 3, since that's all you really need. JMHO,
Jim
