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

good

I bought this on mistake thinking it was jack oil, it is not. It is an addictive. I did however have an old bottle jack that I replaced with hydraulic jack oil and it leaked a little so I added a squirt of this. This stopped the leaking! I had originally bought it to fill a flooorjack but unfortunately it looks like the Lucas oil I need only comes in bucket size.

Sealed iit without using the whole bottle.

Works well

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.

Seems to be doing a good job

Easy to use. Not sure yet if will stop minor seal leak

Not a fan of snake oil additives, but years ago tried lucas power steering conditioner on my 98 Chev pick up that’s has an expensive hydraulic sensor to vary the power steering assist, also fixed a couple of steering racks with morning sickness. So when my jack developed leak and was leking down figured give it try. Drained jack, flushed with alcohol and put in fresh hydraulic oil with the Lucas. Took about 3 days but leaked stop and jack doesn’t leak down.

Cumple muy bien la función excelente 👌 👍 lo recomiendo do 100 %

Conforme

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 .
