Clean, consistent DOT 3 brake fluid from a trusted brand
This brake fluid is exactly what you expect from Prestone. Fresh, clear fluid with no contamination and consistent viscosity. Poured cleanly with no residue or debris in the bottle. Meets DOT 3 specs without issues and works as intended for flushes or top-offs. Pedal feel remains firm after bleeding, with no signs of aeration or performance drop under normal driving conditions. Packaging is solid and easy to handle, and the 32 oz size is practical without being excessive. This is basic maintenance fluid done right—no surprises, no compromises.

Great value, I use them in all my cars
These are great. I use them in all of my cars—Lexus, Scion, and Acura—and they work perfectly. They’re also cheaper than buying the same items at O’Reilly’s by 3 bucks, which makes them an even better value. Highly recommended.
