What Kind of Oil Does A Pressure Washer Use: Different Types

1. Detergent Motor Oil versus Non-Detergent oil

  • Instead of the detergent motor oil that is commonly used in engines, you should use non-detergent pump oil. As pumps don’t have an oil filter, therefore, using detergent motor oil causes the oil to become dirty very quickly.

  • Non-detergent oils designed specifically for pressure washer pumps. These products typically include “pump oil” directly on the label.

All-Purpose Engine Oils

  • All-purpose motor oils contain various designations describing the viscosity of the oil at different temperatures. The label may include: SAE 30,10W-30

  • Here SAE stands for Society of Automotive Engineers and the “W” stands for winter.

  • SAE 30 oil works best in temperatures above 40 degrees Fahrenheit. If you live in a region where temperatures drop below 40 degrees, you may benefit from a multi-viscosity oil such as 10W-40 oil.

How To Change Pressure Washer Pump Oil in 9 Steps:

  • First, you need to purge contaminants from the pump. Connect the pressure washer for use and turn on the water supply.

  • Start the engine and spray the trigger to produce a steady stream of water. Continue holding for about two minutes.

  • After flushing the system, turn off the washer and disconnect it from the water supply. Place a pan or bucket under the pump oil drain plug.

  • If changing the engine oil, drain the fuel and oil from the engine.

  • Remove the oil cap from the water pump. Depending on the model, you may need an Allen wrench to remove the cap.

  • Reattach the drain plug and pour oil into the pump. Replace the oil cap and wipe up excess oil with a rag. The pressure washer is now ready for use.

  • Follow the directions in the user manual to determine how much oil to add to the pump. Premeasured bottles are also available.

Why And When Do You Need To Change The Oil?

Why To Change Oil

  • Oil helps lubricate parts, reducing friction, and wear. When you avoid oil changes, you shorten the service life.

  • By reducing friction, lubrication helps reduce heat. As metal parts heat up, they expand, increasing the risk of cracking and other damage.

  • Not all pressure washers require oil changes. Many residential-use machines come with sealed pumps.

When To Change Oil

  • If you are not sure whether your pump requires oil changes, check the user manual. It should include a section on the topic. This section should also recommend how often the oil needs changing.

  • The typical recommendation is to change the oil after every 200 to 250 hours of use or every three months. If you only use the machine infrequently, you should still change the oil at least once per year.
