Discount Bar's Leaks HJ12 Jack Oil with Stop Leak - 12.5 oz.

Customer Ratings:

I have a cheap Pro-Lift jack that wouldn't raise my car. I checked out the manual, and there was actually a fill hole for adding or changing the hydraulic oil under the name plate. I added some of this oil and popped back in the rubber plug. At first, it didn't seem to help, but after a few hours, I tried again, and the jack rose to its full extension and would lift my car.

I ordered this for a Craftsman jack that was leaking fluid. I figured I'd give this a shot before replacing the jack. The one time I used the jack with this fluid in it, it leaked out all over the floor. Not sure if it actually works or not. The seals in my jack may have just been beyond repair.

I used it on a 25 ton bottle jack used on my big rig that had a slow leak. After using this Jack oil and using it two or three times the leak stopped.
