Recommended Type of Oil for Karcher Pressure Washers
Choosing the right oil for your Karcher pressure washer is essential to ensure optimal performance and longevity. Karcher recommends using a high-quality, non-detergent SAE 30 oil for their pressure washers.
Why SAE 30 oil?
SAE stands for Society of Automotive Engineers, and the number 30 refers to the viscosity of the oil. SAE 30 oil has a higher viscosity, which means it is thicker compared to other types of oil. This viscosity is ideal for providing proper lubrication and protection to the pump’s internal components.
Non-detergent oil is recommended because it does not contain additives that can cause build-up or clog the pump’s valves and seals. Detergent oil, while suitable for some applications, isn’t ideal for pressure washers as it can compromise the effectiveness of the pump.
How to choose the right oil?
When selecting oil for your Karcher pressure washer, it’s important to check the owner’s manual for any specific recommendations or requirements. Some models may have different oil viscosity or brand preferences.
If you don’t have the manual, you can also check the Karcher website or contact their customer support for guidance. They will be able to provide the correct oil specification based on your model number or serial number.
Remember to always use oil that is specifically designed for pressure washers and avoid using automotive engine oil or other types of lubricants. Using the wrong type of oil can lead to poor performance, damage to the pump, and voiding the warranty.
Regularly checking and changing the oil in your Karcher pressure washer is vital to keep it running smoothly and to prolong its lifespan. By using the recommended SAE 30 oil, you can ensure that your pressure washer performs at its best and continues to deliver excellent cleaning results.
