Why do we use oil in a hydraulic jack?

We use oil most of the time since it prevents the jacks from rusting and it allows the item to function smoothly. You should know what oil substitutes you can use for your jack so that you won't damage it. read more

Using an oil as the fluid means the working fluid can also function as a lubricant. read more

Should work okay. The stuff packaged as hydraulic jack oil is low viscosity. A lot of tractor hydraulics and some heavier earthmoving stuff uses hydraulic oil thats essentially the same viscosity as 10W motor oil. Jack oil looks about the same. The main thing is DON'T use brake fluid. read more
