Lucas Oil 10019 Hydraulic Oil Booster/ Stop Leak

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

This seems to work, I used on some hydraulic dampers, where the seals were dried out,(but not cracked), it would have been a big job changing the seals, this swells up the rubber and rejuvenates so no more leaks.

Had a leaking power steering rack on my Ford. This is an mot failure. Put some of this stuff in, no more leaking and my car passed it's mot. Better than paying £300 to get a new rack fitted.

Had a problem with leaking hydraulic cilinder of the cabrioroof from the BMW Z4 after adding the product it needed about 4 days to stop leaking

Would not buy from here again. Took far to long to get it. Product good. Buy elsewhere

I recently had a leak on my car clutch I topped up this and it stopped the leak. Brilliant stuff highly recommend

I had a small leak from the master cylinder on the car.I drained the old fluid,refilled with new fluid and the lucas oil.I have not yet noticed any further leak since applying and able to change gear again.

I put it in my 2 ton trolley jack which had a small leak expecting this stuff to stop it,well it hasn't, it still leaks with oil all ower the place , it didn't work for me but may work for other things I can't say .
