Pressure Washer Pump Oil Change Guide: Step-by-Step Instructions
The oil serves three primary functions: it lubricates the metal-to-metal contacts to prevent galling, it dissipates the heat generated by friction, and it seals the internal clearances to prevent water leakage. The "W" indicates winter performance (low temperature flow), while the number after the dash indicates high-temperature viscosity.
Contaminants such as metal shavings from normal wear, silica from the aggregate in the water, and moisture degrade the oil over time. Draining and Refilling Using a viscosity that is too thin allows oil to leak past the seals and bearings, resulting in metal-on-metal contact and rapid component destruction.
How to Change Your Pressure Washer Pump Oil Correctly
Conversely, using a viscosity that is too thick forces the pump's motor to work harder, leading to overheating and reduced output pressure. Most modern high-pressure pumps are designed to use a 20W-50 synthetic gear oil.
