Just took it out of the box, read the directions. It doesn’t list oil capacity for the engine. Also, do I have to run anything through the washing fluid tank in order to use it?

I think that is a homeowner unit, just so you know this is a professional forum. When in doubt rinse it out. Looks like you bought a cheap chinese unit and it it didn’t come with instructions? Shocking.

here is a link to your manual

Usually there are two oil caps attached to the engine. One has a dipstick on it. You can leave it on a flat surface and keep adding till you see it start coming out the other side.

Google says around .6 quarts
