Pressure Washer Pump Oil

Proper lubrication is the single most important factor in extending the life of your pressure washer pump. Whether you run a triplex plunger pump or an axial cam pump, using the correct pump oil on a regular maintenance schedule prevents premature wear, reduces heat buildup, and protects internal seals and bearings from breakdown.

At North American Pressure Wash Outlet, we stock pump oil formulated specifically for pressure washer pumps — not generic motor oil. Using the right viscosity and formulation matters, especially in hot-climate operation and high-cycle contractor environments.

Why Pump Oil Maintenance Matters

• Prevents scored pistons and worn packing from dry-run friction
• Extends crankcase and bearing life in high-cycle use
• Maintains proper viscosity across temperature ranges
• Reduces the risk of costly pump rebuilds or replacements

Compatible With

• General Pump triplex pumps
• CAT Pumps triplex pumps
• AR Pumps (axial and triplex)
• Comet, Giant, Udor, and other major brands

Always check your pump manufacturer’s manual for recommended oil type and change intervals. Most triplex pumps require an oil change every 250–500 hours of operation or annually, whichever comes first.
