How do you add oil to your jack

[quote=“rugsr”"]

Im going to be buying a new jack soon…racing jack from HF, blue and silver one. But for now I must deal with what I have.

I believe my jack needs oil, no longer hits the height it used to and when it is up there, it slowly drops…or time though, not like within 5 mins.

I see the red cap on the piston that says “add oil” but how and which kind of oil. just drip in motor oil or something?
I heard you have to bleed it too. anyone know?

thanks
