SAE 30 full synthetic in the engine.
SAE 10w30 100% Synthetic oil.
Depends on the manufacture and the size of the pump. These pumps use a special oil so contact the manufacture for the exact amount and type oil.
For the engine, not the pump, 10W-30 is what Briggs puts in them, but SAE 30 is acceptable if your are not running the pressure washer in cold temperatures. I highly recommend you use synthetic oil in any air cooled engine.
Depends on the size engine the pressure washer uses. Just fill it up to the full mark on the dipstick. Use SAE 10w30 synthetic oil.
It uses a multi viscosity non detergent hydraulic oil. It is ISO 68 lubricant. I would use nothing but Cat oil which you can easily buy.
SAE 10w30 Full Synthetic oil any major brand is what to use in the engine. The water pump uses DP70 pump oil or 30w non-detergent oil.
Absolutely not. Use 10w30 high detergent oil just like you use in your lawn mower or vehicle.
No because the gas powered pressure washers do not take oil. They are 4 strokes. Gas only.
Water.
The Honda power washer can use any SAE certified two cycle engine motor oil. The motor oil usually is available in one ounce bottles.
The troy bilt 2200 Pressure washer uses SAE 30 oil for the Motor,and the pump uses Power washer Pump oil you can buy at Lowes in the section selling parts for your power washer. (special oil treated to keep the seals and the pump running ) The pump oil drain is under the unit ,next to the hose connections for the pump .Use a 5/16 allen wrench to remove the black plug drain out old oil and replace with new oil put in the same amount that was taken out. Look under the power washer and you will see a 3/8 plug for the motor oil,I used a 3/8 ratchet wrench long extension to remove this plug,drain out old oil replace plug. Fill to the the full level on the dip stick.
Last resort, if the oil and tar won't come off with regular cleaning brush, you can use a pressure washer surface cleaner from bestcargurus along with your pressure washer, that will surely do the job.
