grey oil is water contamination. check for leaking seals to stop water getting to the oil

Milky-looking oil is a sign of water mixed-in with the oil. This is often a sign of severe engine damage (cracked block, cracked head) in a water-cooled engine. (i.e., one having internal water jackets such as a car engine). On a pressure washer it is sometimes an indication that the owner used the pressure washer on itself, i.e., so as to clean the pressure washer with the pressure washer - very bad idea. If this is the case, then the pressure washer is most likely ruined. In any case the milky-looking oil is a sign that the oil has become contaminated with water, and probably a lot of water. I would drain the oil completely and replace the oil filter too if it has one, then refill the crankcase with new oil. Then try using it again for 10 or 15 minutes or so, then reinspect the oil. If it's milky-looking again then I'd set it out at the curb on trash day.

If you are asking about the oil for the gasoline engine then you can use a 30 weight engine oil like you would use in a car engine. Pressure washer pumps use a special non-detergent oil which is not the same as the engine uses.

Hydraulic oil?
Is this a pressure washer?
Pump should be half full of SAE20 or SAE30 non-detergent motor oil.
Engine should have 10W30 motor oil.

If you have a pressure washer ... and not water is coming out end of gun:
Take all hoses off machine.
Look at incoming water hose connection.
The should be a filter washer.
Clean or replace filter washer.
Hook up water and turn on water.
Water should come out other side of pump.
Turn on power washer and see if water coming out of pump is pressurized.
Now hook up pressure hose without gun.
Turn on pressure washer and see if water comes out of hose and is pressurized.
Finally, the gun may be bad.
We used to replace guns when they went bad.

any anti foaming oil ,you can use multi grade but it goes milky with minute air bubbles and gives the appearance of getting water in.most manufacturers recommend anti-foaming oil

From the manual CleanShot 2050 Briggs and Stratton

Change Pump Oil
1. Drain engine oil and fuel from pressure washer
2. Use an 8 mm allen wrench to remove black pump oil cap between high pressure outlet and garden hose inlet.
3. Tiltl pressure washer to drain oil into an approved container until it drips slowly from pump.
4.Tilt pressure washer in opposite direction and empty premeasured pump oil bottle into same opening (a small funnel may be helpful) [THIS IS WHAT THE MANUAL SAYS-NOT CLEARLY WRITTEN IN MY OPINION OR WRITTEN BY SOMEONE FOR WHOM ENGLISH IS A SECOND LANGUAGE]
5. Install black pump oil cap and tighten firmly.
6. Set pressure washer in upright position. Add fuel and engine oil.

From the engine manual use synthetic 5w-30, 10w-30 from -20 degrees F to temperature of 100 degrees F.
Change oil after 5 hours of operation initially. Before tipping to drain oil, remove fuel from fuel tank by running until tank is empty. Remove oil cap and dipstick and tip engine. Keep spark plug side up. Or remove drain plug from the bottom of pressure washer with a ratchet and square extension and drain oil from bottom. (fuel does not have to be removed)
