Many pressure washer pumps list a specific non-detergent or synthetic pump oil. Check the pump label before topping off, and do not assume the engine oil fits.
Runoff rules
Many cities restrict wash water runoff. Follow local rules, and keep oil and fuel spills out of storm drains.
Products by equipment.
Confirm the lubricant type, grade, and specifications in each equipment manual before ordering.
