Pressure washers, especially Simpson pressure washers, are powerful tools used for a wide range of cleaning tasks. From removing dirt and grime off driveways to cleaning exterior walls, these machines make outdoor cleaning more efficient. However, like any other mechanical tool, regular maintenance is essential for ensuring the longevity and proper performance of your Simpson pressure washer. One of the key maintenance tasks involves using the right type of oil for the engine and the pump. This article will guide you through what type of oil is needed for Simpson pressure washers, why it is important, and how often it should be changed.
Introduction to Simpson Pressure Washers
What is a Simpson Pressure Washer?
Simpson pressure washers are well-known for their durability and high performance in both residential and commercial cleaning tasks. These machines utilize high-powered engines and water pumps to produce a strong jet of water that effectively removes dirt and stains from a variety of surfaces. Simpson pressure washers come in different models, including those powered by gas or electricity.
While they are built for tough cleaning jobs, maintaining your pressure washer by using the correct oil is crucial to prevent wear and tear on the engine and the water pump. Using the wrong type of oil can result in poor performance, potential damage, and even shorter machine life.
Why is Oil Important for Pressure Washers?
The Role of Oil in Engine and Pump Performance
Oil is essential for the proper functioning of both the engine and the pump in a pressure washer. The engine oil keeps the internal components lubricated, reducing friction and preventing parts from overheating. Without adequate lubrication, the engine may overheat, causing parts to wear out prematurely or even seize up entirely.
Similarly, the water pump in a Simpson pressure washer requires proper lubrication to ensure that it operates smoothly. Pump oil prevents the seals and pistons within the pump from wearing out too quickly. Additionally, it helps maintain consistent pressure levels during use, ensuring that your washer delivers optimal cleaning power.
Consequences of Using the Wrong Oil
Using the wrong type of oil in your pressure washer can have several negative consequences. The engine may overheat or struggle to perform at its best if the oil is too thin or too thick for the machine’s requirements. Over time, this can lead to significant damage to the engine and may even cause it to fail. Similarly, using incorrect oil in the water pump may reduce the lifespan of the pump, resulting in costly repairs or replacements.
What Type of Oil for Simpson Pressure Washer?
Oil for the Engine
When it comes to choosing oil for the engine of a Simpson pressure washer, the type of oil you should use depends on the environment in which you operate the machine. SAE 30 oil is commonly recommended for most gas-powered pressure washers, especially in warmer temperatures. This oil works best in temperatures above 40°F (4°C).
However, if you are using the pressure washer in colder temperatures, you may need to switch to SAE 10W-30 oil, which is more suited to colder environments. This oil provides better flow and lubrication during cold starts, preventing wear and tear when the engine first runs in low temperatures.
It is important to check your Simpson pressure washer’s user manual for specific recommendations on engine oil. Using the wrong viscosity can reduce efficiency and cause long-term damage.
Oil for the Pump
The pump in a Simpson pressure washer requires a different type of oil compared to the engine. For most Simpson pressure washers, a non-detergent pump oil is recommended. Non-detergent oils help prevent foaming and bubble formation within the pump, ensuring that the pump runs smoothly without creating pressure imbalances.
Typically, Simpson pressure washers use SAE 30 non-detergent oil for the water pump. It’s important to use non-detergent oil because the design of pressure washer pumps relies on this specific type of lubrication to work correctly. Detergent oils, commonly used in car engines, can interfere with pump operation by creating bubbles that disrupt pressure consistency.
Some pressure washer models may specify the use of synthetic pump oils, which offer improved performance and longevity, especially under high-pressure conditions or when the machine is used frequently. Synthetic oils can withstand higher operating temperatures and provide superior protection against wear, extending the life of the pump.

How to Change the Oil in a Simpson Pressure Washer
When to Change Engine Oil
Changing the oil in your Simpson pressure washer engine is an important part of routine maintenance. It is generally recommended that you change the engine oil after every 50 hours of operation or at least once a year if you use the pressure washer less frequently.
Before changing the oil, make sure the engine is turned off and has cooled down. Place an oil drain pan under the oil drain plug, unscrew the plug, and allow the old oil to drain completely. Once drained, replace the plug and fill the engine with the recommended type and amount of oil. Always check the oil level with the dipstick to ensure it is at the correct level before starting the engine again.
When to Change Pump Oil
Pump oil changes are typically required less frequently than engine oil changes. Most Simpson pressure washer pumps are pre-filled with oil and are designed to last for hundreds of hours before needing an oil change. However, it’s still important to regularly check the oil level in the pump, especially if you use your machine frequently or under heavy loads.
To change the pump oil, locate the pump oil drain plug, unscrew it, and let the oil drain into a container. Once drained, replace the plug and refill the pump with the specified non-detergent pump oil. Be careful not to overfill the pump, as this can lead to excessive pressure and leaks.
Tips for Maintaining Your Simpson Pressure Washer
Regular Oil Checks
Regularly checking the oil levels in both the engine and the pump can help prevent unnecessary damage and extend the lifespan of your Simpson pressure washer. Make it a habit to check the oil before each use, especially if the machine has been sitting unused for a while.
Avoiding Overheating
Ensure that the oil levels are adequate to prevent overheating during operation. If you notice any signs of oil leakage, it’s important to fix the issue as soon as possible to avoid damaging the machine.
Conclusion
Choosing the right type of oil for your Simpson pressure washer is crucial to ensuring its proper functioning and longevity. The engine typically requires SAE 30 or SAE 10W-30 oil, depending on the temperature in which you are operating the machine. The water pump, on the other hand, requires non-detergent SAE 30 oil or synthetic oil to maintain its performance. Regular oil changes and routine checks can help keep your pressure washer running smoothly and prevent damage, ensuring that it remains a reliable tool for all your cleaning tasks.
