In the 2018 Toyota Prius, it is suggested to use brake fluid that meets the specifications of SAE J1703 DOT 3 or SAE J1704 DOT 4. Some options for compatible products are BrakeBest 12 Ounce DOT 4 Brake Fluid or Prestone 12 Ounce DOT 3 Brake Fluid. Brake fluid plays a crucial role in creating pressure for the brake system, which enables the car to stop when the brake pedal is pressed. While it is uncommon for brake fluid levels to decrease, it is advisable to regularly inspect the level when you pop the hood. If you notice a drop in the level, it could indicate a potential leak in the system, and it's important to have your car examined by a professional promptly to address any issues.
The brake fluid recommended for the Toyota Prius is DOT 3, and a reliable choice is Prestone's 12-ounce brake fluid.
