What Type Of Oil Should I Use on My Ryobi Pressure Washer?

A 30w non-detergent oil is typically used in pressure washer pumps. This is because splash lubrication is used in most pressure washer pumps. Rotating “dippers” that spray oil into the pistons and cylinders are used in this operation.

This is the same for Ryobi pressure washers.

All-purpose engine oils are typically the SAE30 type suggested for temperatures above 40oF, therefore if the oil is dark or black, you should change it and use SAE 30 or SAE 10W30.

To avoid forgetting to replace the oil in your pump, schedule it in to your phone on a given date so you know when to do maintenance.
