Can you use sae 30 in a pressure washer?

SAE 30 oil is generally not recommended for use in pressure washers, as these machines typically require specific types of oil for optimal performance. It's best to consult the owner's manual for your pressure washer to determine the appropriate oil type, which is often a non-detergent oil specifically formulated for pressure washers. Using the wrong oil can lead to engine damage or reduced performance. Always follow the manufacturer's guidelines for maintenance and lubrication.
