SAE 15W40 Non-Detergent Pump Oil
Professional Grade High-Pressure Lubricant
This premium SAE 15W40 Non-Detergent Pump Oil is specifically engineered for the high-stress environment of pressure washer pump crankcases. Unlike standard motor oils, this non-detergent formula ensures that water and contaminants settle at the bottom of the crankcase rather than being held in suspension. This prevents foaming and aeration, which can lead to pump cavitation and catastrophic internal damage.
Key Features
- ✔ Non-Detergent: Prevents harmful foaming.
- ✔ Anti-Wear: Protects pistons and plungers.
- ✔ Rust Inhibitors: Protects against water ingress.
- ✔ Thermal Stability: For industrial use.

Questions & Answers
Is this a genuine original part?
This is a premium quality aftermarket replacement oil, manufactured by 4Boats / Aftermarket to meet or exceed original equipment (OE) standards for performance and component protection.
How do I know if it is compatible?
We recommend checking your pump's manual or identifying plate. If it specifies 15W40 or references Simpson 80138, this non-detergent oil is the correct lubricant.
Why can't I use 15W40 engine oil?
Standard engine oil contains detergents designed to suspend contaminants so they can be filtered. Since pressure washer pumps lack filters, detergents cause the oil to foam and emulsify with water, leading to seal failure and cavitation.
Note: Please verify your pump's oil requirements against the references above before purchasing. Always drain old oil completely before refilling. 4Boats / Aftermarket products are engineered for maximum reliability.
