Lucas Oil 10019 Hydraulic Oil Booster and Stop Leak - 1 Quart, White, 32 Ounce

It does the job! I've been able to get 2, 3 ton floor Jack's back on the job.

I bought this for my old floor jack. But when my Kubota loader cylinder front seal started to leak, I put this in to see if it worked. After running it for a while, the leak stopped. Let's see how long it will work for while I wait for the rebuilt kit to arrive.

My 3-ton, shop floor jack was leaking in a couple spots. One leak from the universal joint seal; another from one of the dual piston seals. To buy a seal kit (with no guarantees of proper fitment), was $50. $90 to buy a whole new bottle jack. Lucas Oil Hydraulic stop leak; $12. I drained the oil; flushed it thoroughly with fresh oil, added 10-20% Stop Leak (as the bottle recommends), the rest standard oil, bled it, & as far as I can tell the leaks are gone. The jack held a vehicle in the air overnight, which leads me to believe it's fixed, & that this product works. I'm very satisfied, & recommend it highly to anyone with a leaking floor or bottle jack.

Quality product.

I am a total Lucas devotee, even use their air tool oil. This stuff is thicker than 90 weight though, so it's slow going getting it out of the little nozzle, which is what you ahve to do to fill a jack.. Seems to work though, so I'm happy

I had read a review of this product on a Youtube site about fixing leaky power lifts for outboard motors, which used the word "miraculous". I had a chronic leak on my outboard power lift, and the product was not expensive so I thought I'd try it. It was indeed miraculous!! Totally fixed. I could hardly believe it. Just be patient, it does not go through pumps as fast as regular fluid. I NEVER write reviews but I had to this time.

Best you can buy

Oil has described super fast shipper too!!

I have a 1986 Amman twin drum roller. When I bought it There was various hydraulic electrical and mechanical issues. Anyway I worked my way though them as a project over a 6 month period, everything fixed working perfect so just give it a coat of paint and ready to put it to work. The last job was to fit new clamps to the engine cover so I purchased some here on amazon they arrived I went in the work shop to fit them to see a puddle of hydraulic fluid under the machine. "Gutted" anyway after a quick look it was apparent it was coming from the steering unit the fluid was travelling up the column then running down the outside and eventually to the floor. It was a constant flow and to get to this part isn't easy. The machine is old and I didn't really want to spend lots on it so after a little research I learnt there was various addictive product that may help. To be honest considering how much fluid was coming out I had my doubts but thought it was worth a go, as I'm unsure considering the age of the machine I'd be able to get a replacement part. In the bottle it says to add between 5 and 10% It has a 20L hydraulic tank so I initially put in a bottle which is approximately 5%. To my amazement it reduced the flow within about 10mins considerably. I left the machine running about 30mins whereby it was now a very small leak. The next morning I came out still a small leak so I decided to try some more so now I have approximately 7% addictive after another 30mins of running leak has gone. Obviously early days but all I can advise is this product appears to work. It also suggests it can be used as a preventative measure I have 3 other pieces of plant here varying in age so think I'll buy some more. Definitely worth a try befor a potentially expensive repair

stopped the leak in the cylinder

Good for owners of convertible owners, and owners of Older cars .
