Question about Dewalt DPD3100 Gas Pressure Washer
Hi and welcome to FixYa, I am Kelly
From reading everything I can find, i.e User's manual & parts manual the only thing you add oil too is the engine. The pressure pump does not have a liquid sump.
You can look at parts here detail D:
So too add oil to the engine you would remove the dip stick from the crank case located on the opposite of the side of the engine as the oil sensor.
I recommend you use 30 WT SAE oil for 3 oil changes then on the 4th oil change use an HD 30 WT oil. The oil drain plug is located in the center of the side of the engine crank case base. On the 5th Oil change switch back to SAE 30 WT oil. Oil brands are not really important. They all have to meet SAE the same standards to carry the label of SAE. (Yes you can use a generic 30 WT SAE oil )
Thanks for choosing FixYa,

Testimonial: "Thank you, Kelly! Since there are two plugs that look identical, and the drain plug isn't that obvious, it's really helpful to have your description! "
