you can buy jack-specific oil.
re valves, there are two of interest - one that you open when you want the jack to drop and close when you want it to lift (the raise/lower valve) and another that you open to bleed air (bleed valve). on my jack it is just a rubber plug in the main cyl that you pinch to let the air out. so , procedure looks like this ...
- open the raise/lower valve by one turn and let jack drop to lowest position
- pump 8 times with the raise/lower valve open
- close raise/lower valve and raise jack to max height
- pump 8 more times
- find the bleed valve and release any build-up air
- drop and test
