Please note that Generac’s 2700PSI Residential Power Washer, model number 6022, does not require oil maintenance on the unit’s pump. The unit’s pump has been pre-lubricated and sealed out of manufacturing, which should last for the life of the power washer. The engine itself requires having either a SAE 30, 10W-30, or 5W-30 Synthetic oil filled via the Oil Fill point provided on the unit depending on the ambient temperature that the unit is expected to operate in. The oil recommendation chart in the owner’s manual will assist in determining the proper weight oil. Please note that we recommend utilizing the 5W-30 Synthetic oil for use in areas with significant temperature changes.
