Mi-T-M 18-oz 10w-30 Conventional Pressure Washer Pump Oil.
Most pressure washer pumps use a 30w non-detergent oil. This is because most pressure washer pumps use splash lubrication. This is a process that includes rotating “dippers” that throw oil into the pistons and cylinders.
SAE 10W-30 or SAE 10W-40 are oils that are useful in both hot summer and cold winter days. For example, if you are looking to use your pressure washer and the temperatures are about 40 degrees (F) or less, SAE 10W-30 will be your failsafe option. Anything about 40 degrees, it can still be your best option.

Suitable for use where a straight 15w40 Non-Detergent oil is specified for use in various makes and models of pressure pumps. This high quality oil is blended from virgin base oils and carefully selected additives to help protect washer pumps from corrosion and oxidation.
Pump Oil Viscosity

Viscosity is often the primary consideration when selecting vacuum pump oil. The viscosity of a fluid is a measure of its resistance to flow – so low viscosity is thin and runny while high viscosity is thick and sticky. This is determined by the size of the molecules in the fluid.

Udor recommends 90W gear lube be used in the gear box. Most gear boxes have a sight plug on the side to show the oil level. The oil level should be to the center of the plug.

I bought a troybuilt pressure washer used and i changed the motor oil and ran it maybe 5 minutes.
later i checked the oil level again and it shot out the cap and i noticed the pump oil level is also almost to the top of sight glass. Does anyone know whats wrong?
