Pressure washers are a great way to clean up dirt and grime around the home, but when it comes to maintaining them, things can get a little tricky. One of the most common questions people ask is, “what kind of oil goes in a pressure washer pump?” This question arises when users need to change the oil or are unsure which type to use. Choosing the wrong oil can lead to pump failure, so it’s essential to get it right.
It’s essential to use a high-quality pump oil that is specifically formulated for pressure washers. Most pressure washer pumps require a 30-weight non-detergent oil, but always refer to the manufacturer’s instructions to ensure you’re using the correct oil.
In this blog, we’ll explore the different types of oils available and help you choose the right one for your pressure washer pump.
Types of Pressure Washer Pumps
There are different types of pressure washer pumps available, each with its own specific oil requirements. Here are the types of pressure washer pumps and the different kinds of oil that are suitable for them.
Wobble plate pumps
Wobble plate pumps are a type of pressure washer pump that uses a wobbling motion to create pressure. They are often used in small to medium-sized pressure washers and are known for their compact size and high efficiency.
These pumps are typically powered by electric motors and are capable of generating pressure up to 3000 psi. Wobble plate pumps are also relatively easy to maintain and can be serviced without requiring specialized tools or equipment.
However, they may not be suitable for heavy-duty applications and may require more frequent maintenance than other types of pressure washer pumps.
Axial cam pumps
Axial cam pumps are a type of pressure washer pump that are commonly used in residential and light commercial applications. They are designed to deliver a high volume of water at a relatively low pressure, making them ideal for tasks such as washing cars, decks, and sidewalks.
One of the main benefits of axial cam pumps is their compact size and lightweight design, which makes them easy to maneuver and transport. They are also relatively affordable and easy to maintain, making them a popular choice for homeowners and small business owners.
When it comes to choosing the right type of oil for an axial cam pump, consult the manufacturer’s guidelines. In general, most axial cam pumps require a non-detergent oil that is specifically formulated for use in pressure washer pumps.
Use the right type of oil and to follow the manufacturer’s recommended maintenance schedule to ensure the pump operates effectively and efficiently.
Triplex plunger pumps
Triplex plunger pumps are a type of pressure washer pump that use three plungers to create high pressure water flow. They are typically used for heavy-duty cleaning tasks and are known for their durability and efficiency.
Triplex plunger pumps are commonly found in commercial and industrial pressure washers, but can also be used in residential models for more demanding cleaning jobs.
When it comes to choosing the right oil for a triplex plunger pump, consult the manufacturer’s guidelines to ensure that the pump is properly lubricated and maintained.
Identifying the Right Oil for Your Pressure Washer Pump
Following are the different types of oil that are suitable for pressure washer pumps and help you identify the right oil for your specific pressure washer model.
Factors to consider when choosing oil
When choosing oil for your pressure washer pump, there are several factors to consider. These include the viscosity grade of the oil, whether it is synthetic or mineral-based, and the operating temperature range.
Check the manufacturer’s recommendations for the specific type of oil that should be used in your pressure washer pump. Using the wrong type of oil can cause damage to the pump and reduce its performance.
Manufacturer’s recommendations
When it comes to choosing the right oil for your pressure washer pump, it’s always best to follow the manufacturer’s recommendations. Different pumps require different types of oil, and using the wrong type can cause damage to your equipment or reduce its efficiency.
Check your owner’s manual or contact the manufacturer to find out what type of oil is recommended for your specific pressure washer model. Note that using high-quality oil and changing it regularly can extend the life of your pressure washer pump.
Viscosity requirements for different pump types
Different types of pressure washer pumps require different viscosities of oil for optimal performance. Axial pumps typically require a lower viscosity oil such as SAE 15W-40 or 10W-30, while triplex pumps require a higher viscosity oil such as SAE 30 or 40.
Consult the manufacturer’s specifications to determine the correct viscosity for your specific pressure washer pump. Using the wrong viscosity of oil can lead to damage and decreased efficiency of your pressure washer pump.
Commonly Recommended Oils for Pressure Washer Pumps
Here is a look at the commonly recommended oils for pressure washer pumps, and provide you with the information you need to make an informed decision.
Non-detergent pump oils
Non-detergent pump oils are a type of oil that is commonly recommended for pressure washer pumps. They are specially formulated to provide superior lubrication and protection to the pump’s components, such as the pistons and valves, without leaving any harmful residue or buildup.
Non-detergent pump oils also help to prevent rust and corrosion, which can be caused by the water used in pressure washing. Note that using the wrong type of oil can damage the pump and void its warranty, so it is crucial to always follow the manufacturer’s recommended oil specifications.
SAE 30 oils
SAE 30 oils are one of the commonly recommended oils for pressure washer pumps. These oils are ideal for use in warmer temperatures and are commonly used in smaller pressure washer pumps.
Check the manufacturer’s recommendations before using any type of oil in your pressure washer pump to ensure the best performance and longevity of your equipment.
Synthetic oils
Synthetic oils are becoming increasingly popular for use in pressure washer pumps due to their superior performance and longevity compared to conventional oils. They have higher viscosity indexes and can withstand extreme temperatures, which is crucial for pressure washer pumps that operate at high temperatures.
Synthetic oils offer better protection against wear and tear, reducing the need for frequent oil changes. When selecting a synthetic oil for your pressure washer pump, be sure to choose one that is compatible with the pump’s seals and materials.
Follow the manufacturer’s recommendations for oil type and viscosity to ensure optimal pump performance and lifespan.
Multi-grade engine oils
Multi-grade engine oils are commonly recommended for pressure washer pumps because they provide better protection against wear and tear compared to single-grade oils. They are also more versatile as they can be used in a wide range of temperatures.
However, use the right viscosity rating as recommended by the manufacturer to ensure optimal performance and longevity of the pressure washer pump.
Changing the Oil in Your Pressure Washer Pump
The pump is the heart of your pressure washer, and it needs clean and adequate lubrication to work effectively. Here is the importance of changing the oil in your pressure washer pump and answer the question of what kind of oil goes in a pressure washer pump.
