Recommended Oil and Other Gas Pressure Washers Tips You Need to Know

If you need to clean larger surface areas fast and easily, a gas pressure washer will be your best option. It cleans 3 times faster than an electric pressure washer, and offers greater mobility since there are no electrical cords in your way.

However, there are steps that you need to take before you can start your heavy-duty job and that includes adding oil. If you are asking what kind of oil you should use for a pressure washer, the answer will be what the manufacturer recommends. That’s why it is important to read the manual carefully before purchasing anything or beginning your task.

Meanwhile, for small gas engines like pressure washers have, the oils used are very similar to each other. Most of them would need 30w non-detergent or 4-stroke engine lubricant because they are compatible with splash lubrication.

So it does not really matter what kind of oil you use for a pressure washer or what brand name it carries because they will probably provide the same result. For example, what you use for a Honda GX is most likely suitable for a Subaru and other pressure washers. So the more important question is how to set up a pressure washer and perform an oil pump change. The steps are easy.

Steps for setting up a gas pressure washer

  1. Check the engine lubricant to know how much oil is still there. Never start it if the oil level is too low and do no overfill the engine crankcase because it will cause excessive smoke or even engine damage. Just add enough oil for a day’s use.
  2. Fill the tank with gasoline or diesel fuel. If your pressure washer is small, you can use gasoline, but for commercial models, diesel fuel is most suitable.
  3. Set the cleaning attachment of your choice by attaching the extension wand. It would be better if you have a spray gun.
  4. Connect one end of the high-pressure hose to the inlet of the pressure washer while the other one to the spray gun. Make sure to tighten everything that you attach.
  5. Connect one end of the garden hose to the faucet or your water supply and let the water run until it’s clear. To connect the other end to another inlet of the pressure washer, you need to thread a coupler on the garden hose.
  6. Start the engine using the choke or primer bulb. The tool you use to prime the carburetor depends on the model. Pull the start cord, then adjust the handle or throttle according to the speed recommended by the manufacturer.
  7. Try squirting water by spraying the spray gun on a place where nothing will be harmed. Test if the pressure is enough and adjust if needed. Just release the trigger to pause.

Steps for performing an oil pump change

  1. Turn on the pressure washer and let it run for up to 10 minutes; this is to warm the engine oil up so it will flow better. It is easier to drain warm oil than cold oil. Be careful in doing this step because the unit may be hot to touch.
  2. Do not tilt the pressure washer yet. Instead, place it on a flat surface.
  3. You can extract the oil from the pump by removing the drain plug and placing an oil pan on the bottom or sucking the oil with a suction gun. Another method to pump it out is to use an electrical suction pump.
  4. Set aside the used oil. You may opt to bring it to a recycling facility so it can be cleaned and used again; you don’t need to throw it out.
  5. Put the drain plug back in the pressure washer before filling the pump with new oil.
  6. Open the oil cap and use a funnel when filling the pump so that no oil will spill. Make sure not to overfill it; add the amount recommended by the manufacturer.
  7. Check the engine lubricant again to see if there is enough oil, and add if needed.

Follow the steps above for setting up your gas pressure washer and if you need to do an oil change.
