Core Principles of Engine Oil Selection
The power system of a high-pressure washer is like the heart of the human body; choosing the right engine oil is essential for maintaining strong power. Depending on the type of equipment:
Plunger pump models: Mineral oil or semi-synthetic oil with a viscosity of 30-40 is recommended.
Axial pump models: Fully synthetic oil with a viscosity of 20-30 is recommended.
For use in cold regions: A 5W-30 oil with better low-temperature fluidity is required.
