Would anyone happen to know what sort of oil is used in a 1850kg trolley jack?

Yes, hydraulic oil. Auto trans fluid, power steering fluid. Rus.

Hi Derek, do you know any of the other properties? We use several different types of hydraulic fluid at work but we use bleep s...
Thanks mate

I have a product that goes by the imaginative name of "jack oil" made by Jamec-Pen and suitable for "pipe benders, hydraulic presses, porta-power cyclinders and garage and bottle jacks" Got it form Repco so long ago I've forgotten when. Only used it once.

There's only one problem with that Bruce, I can't get "jack-oil" for free...

It's only a trolley jack.

Just use clean engine oil any grade.

Because it is totally the wrong type of oil.

Courtesy of Google:

"All hydraulic systems start with oil. Oil is the lifeblood of the beast. Since oil is a liquid it cannot be compressed. That means it will flow and transmit power virtually anywhere. As with any fluid this form of power transmission needs to be channeled and told where to go. In simple terms that is what a hydraulic system does. The oil is the lubricant and vehicle for transmission of this power. Hydraulic oil is not just any oil. It is formulated to withstand a wide variety of temperatures and has additives that control its reaction to the rubber seals and plastic parts found in the components of the system. A wrong oil type can cause o-ring swelling and dissolve seals. Use only hydraulic oil recommended for your application."

An hydraulic jack would work with water, but would you use it?
Using your theory we might as well just put engine oil in everything, engine, gearbox, diff, power steering, auto trans etc etc.

From my own library

1. Hydraulic power is nearly always generated from mechanical power. Example: A hydraulic pump driven by an engine crankshaft.

2. Hydraulic power output is nearly always achieved by converting back to mechanical energy. Example: A cylinder, which raises a heavy object.

3. There are three types of hydraulic energy:
a) potential or pressure energy
b) kinetic energy, the energy of moving liquids
c) heat energy, the energy of resistance to flow, or friction

4. Hydraulic energy is "neither" created nor destroyed; only converted to another form.

5. All energy put into a hydraulic system must come out either as work (gain) or as heat (loss).

6. When a moving liquid is restricted, heat is created and there is a loss of potential energy (pressure) for doing work. Example: A tube or hose that is too small or is restricted. Orifices and relief valves are also restriction but are purposely designed into the system.

7. Flow through an orifice or restriction causes a pressure drop.

8. Oil must be confined to create pressure for work. A tightly sealed system is a must in hydraulics.

9. Oil takes the course of least resistance.

10. Oil is normally pushed into a pump, not drawn into it. (Atmospheric pressure supplies this push). For this reason, an air vent is needed in the top of the reservoir.

11. A pump does not pump pressure; it creates flow. Pressure is caused by resistance to flow.

12. Two hydraulic systems may produce the same power output, one at high pressure and low flow, and the other at low pressure and high flow.

13. A basic system must include four components: a reservoir to store the oil; a pump to push the oil through the system; valves to control pressure and flow; and a cylinder (or motor) to convert the movement into work.

14. Compare the two major hydraulic systems:
a) Open centre system = pressure is varied but flow is constant.
b) Closed centre system = flow is varied but pressure is constant.

15. There are two basic types of hydraulics:
a) Hydrodynamics is the use of fluid at high speeds "on impact" to supply power. Example: a torque converter.
b) Hydrostatics

It's only a jack!

Case still run engine oil in there skid steer loaders as it save the owner runing two oils

I think I'll just try the first hydraulic fluid I find at work... Not, Richard, because I doubt that engine oil will work, just because I can get the hydro for free... Sound like a tight-arse don't I...??? I just don't believe in paying when something can be had for nicks...

Hmmmm ....... So, jack manufacturers use engine oil?

I know years ago BMC (later Leyland) had torque converters that ran in engine oil, but it is very uncommon.

"Hmmmm ....... So, jack manufacturers use engine oil?"

These are your assumptions

Not mine

I could go on for ever

And quote a lot of Technical Information if you wont, none of it's not mine!!!
