Why Does a Pressure Washer Pump Need Oil?

Best Pressure Washer Pump OilIt doesn’t matter if you’re a professional who washes cars, machinery, or buildings on a daily basis, or you’re a homeowner who mostly uses a pressure washer to clean your home vinyl siding once a year – if you at some point invested in a pressure washer, you want it to last a long time. Just like with any type of machinery, your pressure washer requires regular maintenance to work well. An important part of maintenance is oiling your pump.

It’s quite simple: to work, the inner parts of a pressure washer pump need to move at great speeds. When parts that touch one another move, the movement creates friction between them. Friction creates heat, and the longer or the faster the parts move, the bigger the chances of overheating become. Excess heat can easily cause damage to parts of the pump, some due to the material not being able to withstand the heat (for example rubber that melts), and others due to the expansion of materials or water that happens at high temperatures. It’s easy to see how easily this simple issue can result in a disaster.

To prevent the buildup of friction, there has to be lubrication between the moving parts. Lubrication makes sliding next to one another easier for the parts and heavily reduces, nearly nullifying friction. This prevents overheating and helps your pressure washer pump live a long, happy life.

1. Which Type of Pressure Washer Pumps Needs Oil Changes?

Whether or not you should change the oil in your pressure washer pump depends on the type of pump your washer utilizes. There are three types of pressure washer pumps that are commonly used in commercially available models, and only one of these types actually requires pressure washer oil changes.

1.1. Axial Cam and Wobble Plate Pumps

If your pressure washer puts out pressure lower than 2500 PSI or uses a water flow weaker than 2 GPM, chances are that it uses a wobble plate or an axial cam pump. These two types of lower-rated pressure washer pumps are factory sealed, and that means that they don’t need oil changes. It’s simple – these are very cheap to make and replace, so when it stops working, it’s cheap enough to replace them.

However, you should note that the PSI and GPM rating alone is not a foolproof way of determining your washer’s pump type. If you have a gas pressure washer with exposed components, you can determine the type of pump just by looking at it. If you own a model that is covered in a plastic casing, check your washer’s specifications in the user manual or on the manufacturer’s website to find out which type of pump it uses.

1.2. Triplex Pumps

It doesn’t matter if you own a gas or an electric-powered pressure washer: triplex pumps are common in every type of washer for their supreme power and durability. This type of pump utilizes three pistons to pump out water at consistently high pressure, and because of this unique construction, they’re very easy to recognize.

Replacing a triplex power washer pump is expensive, as they have an intricate design. On the other hand, they have a virtually unlimited lifespan, but of course, they can break due to overheating. Because of that, regular maintenance and oil changes make all the difference in the longevity of your pressure washer.

Pressure Washer Pump Oil Buying Guide

Pressure Washer Pump Oil Buying GuideGetting the right pressure washer pump oil is not too difficult. However, if you pick the wrong one, you can cause irreparable damage to the pump of your pressure washer. The likely result of using the wrong type of oil is a necessary pressure washer pump replacement. Because of that, you should find out what the best type of oil for your pressure washer is, and get that specific type of oil. Here are some important tidbits you should know before you go oil shopping.

1. Manufacturer Recommendation

The first thing you should check is whether the manufacturer of your pressure washer has a pump oil recommendation. The first step in an oil change should be checking the user manual or the manufacturer’s website for the proper type of oil.

Some manufacturers even make and sell their own oils that are developed to completely match the design of the pumps they use in their pressure washers. Others simply recommend the type of oil that suits the pump well.

Don’t skip this step. There are many kinds of oil out there and the wrong type can cause damage to your pressure washer pump, making costly replacements necessary. It’s better to be safe than sorry.

2. Non-Detergent Oil

The single most important distinction between regular motor oil and oil designed for pressure washer pumps is that regular oil often contains detergents. The role of detergents is to pick up contaminants as it flows through the engine and bring them to the oil filter, keeping the engine clean. However, water pumps don’t have an oil filter, making this procedure downright dangerous. You simply don’t want these contaminants flowing through your pump over and over again – it can quickly wear the pump off.

In fact, you should always look for the designation ND – which stands for Non-Detergent when getting pump oil. These usually also contain anti-foaming and anti-aerating additives, which prevents the formation of bubbles inside the pump. Foam bubbles can cause serious damage in the form of cavitation, which can damage the pump. As you can imagine, oils with detergents tend to foam up a lot, which doesn’t harm a regular car engine but can be deadly for your pressure washer pump.

3. Viscosity

When looking for a power washer pump oil you’ll notice that there is a specific system of codes that label these oils. So, you might see something like SAE 10W-30. To understand what this means, we need to discuss viscosity.

The simplest (though informal and incomplete) way to describe viscosity is as “thickness” of a liquid. You already know that peanut butter is thicker than syrup, and syrup is thicker than water. However, the thickness of peanut butter changes depending on the temperature, and it flows much better (gets “thinner”) when it’s hot, and seems icy-still when right out of the refrigerator.

In essence, the SAE designation tells you how viscose the oil is, or how easily it will flow through the pump. If there are two numbers separated with the letter W, you get the viscosity in both cold and hot environments. So, in SAE 10W-30, in winter (W) the viscosity is 10, and it rises up to 30 in warm temperatures. The higher the number, the “thinner” the oil is.

When it comes to hydraulic oil, these will be graded on the ISO scale, but they tell you the same thing. ISO 32 translates to SAE 10W, ISO 46 and 68 are approximately the same as SAE 20, and ISO 100 is equivalent to SAE 30. When it comes to gear oil, things can get confusing: SAE 75W-90 gear oil is about the same viscosity as SAE 10W-40 engine oil, so the distinction between oil types is important.

Most pressure washer pumps use SAE 10W-30 or SAE 10W-40 oil. However, you should always check the manufacturer’s recommendation for pump oil, and avoid using your pressure washer on freezing-cold winter days and the hottest days of the year.

4. Additives

Most pump oils come enriched with specific additives that make them even more helpful for keeping your pressure washer pump in its top condition. The most common additives in pressure washer oils are anti-rust additives that prevent corrosion, and anti-foaming and anti-aeration additives that control the amount of air in the pump. As we mentioned before, pump oil must not contain detergents that are present in regular car engine oil because pumps don’t come with a filter.

How to Change Pressure Washer Pump Oil?

How to Change Pressure Washer Pump OilChanging your pressure washer pump oil will ensure it lasts a long time and works with no issues. It’s a rather simple task, and it should take you about an hour to do it together with unmounting and mounting the pump back on the frame.

1. When to Change Pump Oil

The first time you change the oil in your new pressure washer is after the first 50 hours of use. After that, you should change the oil every 100 hours of work, or every 3 months – depending on what comes sooner.

Most triplex pumps come with a sight glass – generally a circle with a dot which shows how much oil should be there. If you notice that the oil level is under the dot, your pump needs more oil – but it’s much safer to drain and pour new oil than to merely add a bit. If your pressure pump doesn’t have a sight glass, check if it has a dipstick, or if the user manual recommends a particular amount of oil you should pour into your pump.

You should also change the oil if it’s leaking (of course, after detecting and repairing the problem), or if it’s a milky color.

2. What You Need to Change Pump Oil

  • Oil catch – a tray or bowl to drain the oil in
  • Wrench – to loosen up the bolt access. Not necessary if your pump has a plastic access knob
  • Funnel – to avoid spilling when pouring oil
  • Appropriate pressure washer pump oil

3. Steps to Changing Pump Oil

  • Remove the pump assembly (usually together with the motor) and set it up on your workstation.
  • Detect all bolts that you’ll need to use. You should have a drain bolt and a top access bolt. However, some pumps only have one.
  • Remove the top access bolt so that the air pressure inside is relieved.
  • Set up your oil catch under the pump’s drain access, and open it. Let all the oil flow out, and shift the position of the pump to make sure everything comes out.
  • Put the drain bolt back and tighten it.
  • Get your funnel and pour the pump oil through the top access. The reservoir shouldn’t be completely full. If your pump has a sight glass, make sure the level matches the dot. If not, check your user manual to find the specific amount it needs. Most pumps need approximately 12 fluid ounces of oil to work properly. Make sure you don’t overfill the reservoir, but also that you pour enough oil.
  • Place the top access bolt back and tighten it.
  • Mount the assembly back on your pressure washer after cleaning up any spillage.

FAQ About Pressure Washer Oils

1. How should I dispose of used pump oil?

Recycling used oil is the most productive way to get rid of it, as it saves this valuable resource. Oil doesn’t really wear out, and it only needs to be cleaned with professional tools to be ready to use again. In fact, according to the EPA, to produce 2.5 quarts of lubricating oil you need either one gallon of used oil or as much as 42 gallons of crude oil.

After you catch all the drained oil on your oil catch, pour it into an empty bottle, and bring it to a recycler. Most local car mechanic shops and recycling centers will accept it. If you don’t have any nearby, try Jiffy Lube or similar. If there aren’t any near your place, you can even check if your local big supermarket accepts used oil.

If you can’t find any of those, you should call your local dump to check if they accept used oil, since many do. However, this is the least eco-friendly option, as oil that ends up in the soil and local bodies of water can seriously harm wildlife in your area.

2. What is the difference between synthetic and natural oil?

In your search for power washer oil, you might have to pick between conventional natural oil and synthetic oil. Let us tell you right away that you can use either of these and your pump will do just fine – but there are still some differences between them.

Synthetic oil is much harder to make, but its quality and purity are overall much higher. That’s because the manufacturer has total control over every aspect of the product down to the molecular level. In general, synthetic oils have somewhat better performance and longer durability as it doesn’t get dirty as fast. However, that also means that synthetic oil is much more expensive. The choice between the two is entirely up to you – with a regular oil change schedule, conventional oil will do just as well as synthetic.

Wrap Up

There you have it, that’s all the most important information you need about choosing the best pressure washer pump oil for your machine. You use your pressure washer to maintain your garage, yard, house, and work tools in their best shape, but doing regular maintenance is imperative for helping the machine keep its peak performance. Changing your pressure washer oil is only one of the important tasks you should do, but it’s easy and simple enough: You just need a bottle of well-fitting oil and a bit of time every 3 months to do it right.
