Oil for Pressure Washer Pumps

Maintaining cleaning oil in your pressure washer pump, as well as keeping sufficient levels, is one of the best things you can do to preserve it and make it last as long as possible. Properly lubricating your pressure wash pump protects the inner components, allowing them to run smoothly with minimal friction and abuse. Pressure washing pump oil is available in a variety of sizes, so you can stock up with larger multi-gallon jugs if you run several pressure washers regularly, or buy smaller quart bottles if you're a smaller operation with only one or two pressure washers.

When buying pump oil for your pressure washer, take note of the manufacturer that made the pump. Although your pressure washing unit might have a brand that built it, they often use a pump from a company that specializes in pumps, like General Pump or CAT. Most pressure wash pump manufacturers produce their own specially formulated blends that work best with their pumps. Not only will the pump perform well and last longer, using the recommended oil is often required to maintain any warranties or guarantees.
