Legacy Pump Oil is a quality mineral base lubricating oil ideal for use in high pressure piston, precision plunger pumps, blended with wear, rust, and foam inhibitors. Northstar Clean Concepts does not recommend the use of motor, transmission, hydraulic or compressor oils in pressure washer pumps.

Milky pump oil can be caused by condensation in the crankcase or seal wear. If the pump is allowed to run after the low-pressure seals and high-pressure seals have become worn, water may eventually travel back along the plunger rod and past the oil seal. Water is a contaminant to the crankcase oil and can cause damage to the drive-end components. The water will cause the oil color to change to a milky consistency initially and in severe situations can cause damage to the drive-end.

Crankcase oil should be changed after the initial 50-hour running period, then every 500 hours thereafter.
