I went to the auto part store for some dot 4 fluid all they had was valvaline synthetic dot 3&4 all in one fluid. can I use this to flush my brakes
Yep, I guess you could call all of them synthetic since each manufacture has their own "formula". The end result is they all have to meet a specification.Roamrider said:Just a smart a** question, but, silicone DOT 5 aside, aren't all DOT 3 & 4 brake fluids "synthetic" in the sense that they're not "natural" oil products? Asked another way, what's the difference between synthetic DOT 4 and "regular" DOT 4 brake fluid?
But wait - there's MORE!seahabit said:So it sounds like we're all in agreement here. Dot 3, Dot 4, and Dot 3 and 4 are not silicone base.
And by the way Ron, the fluid I use is distilled from the tear ducts of the Sierra spotted yellow-legged frog.
