Store pump oil in a cool, dry place to prevent degradation. Avoid exposure to extreme temperatures, which can affect the oil’s performance. Use the proper oil for your specific pressure washer model to ensure compatibility and effectiveness.

Periodically inspect the pump for any signs of wear or leaks. Addressing issues early can prevent further damage and maintain the efficiency of your pressure washer.

Keep the oil container sealed when not in use to prevent contamination. Proper sealing helps maintain the oil’s quality and effectiveness over time.

One common mistake is using the wrong type of oil. Always refer to your pressure washer’s manual for recommended oil specifications, as using incompatible oil can lead to damage.

Another mistake is neglecting regular oil changes. Old or degraded oil can affect pump performance and lead to costly repairs. Establish a maintenance schedule to replace the oil as needed.

Some buyers overlook the importance of viscosity. Choosing an oil with the wrong viscosity rating can result in inadequate lubrication, leading to pump wear. Always choose oil that matches your operating conditions.

Finally, failing to check for rust and oxidation protection can be detrimental. Using oil without these protective features can shorten the lifespan of your pump. Always prioritize oils that offer these essential protections.
