Considering this, why does my floor jack not stay up?
Another possible reason why the floor jack's ram won't lift is due to lack of enough oil in the reservoir. When this occurs, the air starts to accumulate in the unit preventing it to lift. Be sure to check the levels of the hydraulic fluid regularly.
Beside above, can I use motor oil in a hydraulic jack? Machine oil or lightweight motor oil of 10/20W can be substituted for hydraulic fluid. Automatic transmission fluid can function as hydraulic fluid. Use it if you are stuck and do not have the oil recommended by the manufacturer. There are a few vegetable seed oils that can be commercially used as hydraulic fluids.
Herein, can floor jacks be repaired?
A hydraulic floor jack is used to lift heavy vehicles to be able to work underneath them. When a hydraulic floor jack is not operating properly, it can be repaired quite easily with basic tools.
