Vehicle fluid capacity is the maximum amount of a certain type of fluid recommended for a vehicle. Fluid capacities are listed in the vehicle's owners manual. The manual typically lists capacities for motor oil, transmission fluid, brake fluid and power steering fluid.
Fluid capacities are also listed on manufacturer websites. Recommended fluid levels are marked on the fluid dipstick, and many manufacturers leave extra room above the recommended level to prevent overfilling. Oil capacity is typically indicated with and without the filter installed. Fluid capacity websites, such as FluidCapacity.com, allow a user to search fluid capacities by make and model of the vehicle without the need of the owner's manual.
