Motor oil is specifically designed for use in engines and is formulated to withstand high temperatures and pressures. It is typically made from a combination of base oils and various additives to improve its performance.
On the other hand, pump oil is specially formulated for use in pressure washer pumps. It is designed to provide lubrication and ensure the smooth operation of the pump’s internal components, such as the pistons, valves, and seals.
Viscosity:
Viscosity refers to the thickness or resistance to flow of a liquid. Motor oil usually has a higher viscosity compared to pump oil. This is because engines require a thicker oil to create a protective barrier between moving parts under high temperatures and pressures. Pump oil, on the other hand, has a lower viscosity to ensure smooth flow and reduce friction within the pressure washer pump.
Additives:
Motor oil contains various additives such as detergents, dispersants, antioxidants, and anti-wear agents. These additives help to clean the engine, prevent the formation of deposits, and protect against wear and corrosion.
Pump oil, on the other hand, contains additives that are specifically designed for the needs of pressure washer pumps. These additives help to enhance the lubrication properties of the oil, protect against oxidation and rust, and maintain the proper functioning of the pump’s internal components.
| Comparison | Motor Oil | Pump Oil |
|---|---|---|
| Application | Engine lubrication | Pressure washer pump lubrication |
| Composition | Base oils + additives | Specially formulated additives |
| Viscosity | Higher viscosity | Lower viscosity |
| Additives | Detergents, dispersants, antioxidants, anti-wear agents | Pump-specific additives |
