About this item

  • *NOT AVAILABLE IN CANADA

    Fights Water Contamination
    Water contaminates the brake system by seeping through microscopic pores in flexible brake lines and seals and through the reservoir fill cap. Brake fluid itself is hygroscopic (attracts moisture). Once introduced to the system, water reduces boiling points and compromises performance. It corrodes brake parts, lines and seals, leading to eventual failure. AMSOIL DOT 3 & 4 Synthetic Brake Fluid's superior wet boiling points counteract these problems. It lubricates and protects intricate brake components despite the inevitable water contamination. A nitrogen blanket is added to each bottle during manufacturing to purge moisture and ensure the maximum level of performance.

    Firm Pedal Feel
    The extreme pressure and high heat common to brake systems can push brake fluid beyond its boiling point, causing it to vaporize or "boil-off." Water contamination can accelerate the process. This leads to a spongy or unresponsive feeling in the brake pedal (vapor lock). In contrast, the unique chemistry behind AMSOIL synthetic brake fluids increases boiling points well beyond DOT standards, even when contaminated with 3.7 percent water. AMSOIL Brake Fluids maintain a stable viscosity over a wide temperature range and flow easily at the high pressures generated in today's automotive brake systems to deliver solid, reliable braking. Maximum ABS and Traction-Control Performance AMSOIL DOT 3 & 4 Synthetic Brake Fluid's low-viscosity (817 cSt) provides superior cold-weather performance and excellent ABS and traction-control responsiveness. It covers a broad range of applications and exceeds DOT 3, 4 and 5.1 specifications.

    APPLICATIONS
    Use AMSOIL DOT 3 & 4 Synthetic Brake Fluid in passenger car, light truck and powersports applications that require a DOT 3, 4 or 5.1 product. Do not mix with DOT 5 fluid. Refer to your owner's manual regarding the proper change interval for your brake fluid and to determine the correct DOT classification. Change fluid every two years for maximum performance.

      Top Quality for everything dot 3 or 4
      By  RICHARD,  a  Verified Buyer  from  Ontario, California   on  April 30, 2026
      I change my fluid in my 2022 road king special every 2 years. Even in the dry climate of the Inland Empire there's still moisture in the lines after 2 years. The fluid is clear with a very light yellow tint to it. Significantly light than the stuff going out. I use this on a 2003 dodge ram, a 2012 honda civic, a 2005 Tacoma and a 87 porsche. Never an issue, never a stuck brake and the pedal always feels like new. This is the best I've ever used.
      Bottom Line
      Yes, I would recommend this to a friend.
