You're lucky he found them - they are not easy to locate. Many folks use hydraulic jack oil which you should be able to buy at any auto parts supply store. I've used Mobil Hydraulic oil DTE-24 (SAE 10) for many years and would recommend it if you can find it. Yet others use motorcycle fork oil which apparently is satisfactory. If they leak excessively you might try a SAE 20 hydraulic oil like Mobil's DTE-25, but a rebuild might be in the cards.

Fill to the bottom of the filling port, work the arm up and down a few times to expell any trapped air, and check the level again and top off if needed.

CORRECTION: Mobil DTE-25 is an SAE 20 hydraulic fluid, not SAE 30. Sorry
