No extra force in oil, it works just the same as a lifter it's an EHD thruster, called "ion drag pump" when the medium is a dielectric liquid and the thruster is stationary: oil molecules are ionized, and ion current from a sharper electrode to a flatter electrode entrains neutrals.
You can picture an EHD thruster as a paddle wheel boat: while the charges carried by the ions (=paddles) move through the medium (=water) they drag it backwards, the rest of the time they are recirculated from the back to the front of the thruster by the power supply (= the boat's engine).
