That's interesting, I've never heard of hydraulic stop leak.
I presume it is supposed to"stop leaks" then?
How well does it work? How often does your brother go through those 5 gallon buckets?

I've use dit in 'known' leaky system as a bandaid to get by.
For instance.. I picked up an antique loader that had been setting in a field for ? decades? Thankfully hte prev owner had greased the rods, and put 'some kind' of oil in the cylinders and capepd them off...
Well.. when i got it all installed.. bled and refilled.. the main lift cyl weeped pretty good... I neede dit for immediate hurricane cleanup work so put some lucas stop leak in it.. not sure if it was atf stopleak or pow steer stop leak.. but I'm guessing it's the same any way.
Leak virtually disappeared for 4 months or so. then finally re-emerged.. this time.. comeing out in a stream... I bti the bullet and pad the 90$ to get the 50 year old cyl repacked... It's dray as a bone now and hold up under weight for as long as I dare let it..

I wouldn't use it in anything. It is just like putting stuff in a radiator to plug the holes. If you have a hydro or a transmission with hydraulic clutches, you don't want anything that can swell seals, plug passages or contaminate clutches or you can have a very expensive repair. Any hydraulic leak needs to be repaired properly because you wallet and health are at risk.
Older tractors with dry clutches and standard transmissions might be able to use it without damage as a temporary measure.

The only product I have first hand experience with is TRC's Seal Saver Plus. They have been selling it for a few years now and so far all of the customers that I have sold it to have been very pleased with the results. I mainly sell it to construction companys, large industrial companys and golf courses. To date I have not had anyone that had any problems created from it's use. It does not appear to have any negative effects on the performance or life of wet clutch/brake systems. It also contains a additive booster package.
Now personally I have never really pushed the sale of such products. TRC makes a few additive type products that work well but personally I would rather see a customer have the equipment repaired and then use a good quality lubricant that contains seal conditioners to maintain it.

Jerry brings up a good point. The tractor in question i used it on has a seperate hyds only sump, and seperate hyd pump just for the lift and laoder hyds... no oil shareing with the trans or diffy like in some common sump machines.

Stop leak products in ANY form don't set well with me. They're like putting extra bailing buckets in a leaky boat instead of fixing the leak. In an emergency, I suppose it could get you through for a time, but in the long term, I'd prefer to fix the problem rather than mask it. Band aide fixes have a way of coming undone at the worst possible opportunity. And that doesn't even address the possibilities of damage to components in a hydraulic system caused by exposing them to what is basically an incorrect oil mixture.

Sounds like a "BAND AID"to me , If a hydraulic system leaks ,Fix it because it's going to let you down .
I've used rad stop leak in an "emergency" and some times it works but with a rad you can't see the problem and some times don't know where it's coming from . But a hydraulic system is pretty simple and oil leaks are messy and obvious . What are you trying to stop leaking ,If a hose is gone it's"GONE"and if it's a fitting they are cheap or if your a fiddler use thread tape ?
Why mess with this stuff ,Only a small amount ends up where you want it ,The rest is in your filters and pump and on a new machine if found on an oil analysis could void any warranty.

would this stuff work in a clutch slave cylinder? the seals are goin out and it leaks, there is still pressure in the system but it gets annoying after a while because the clutch wont disengage because the system doesnt have enough pressure in it because it leaks.. any suggestions?..

the real answer is to fix it.
who wants a clutch not working.. and why contaminate the system.
I used it as a stop gap on my laoder as I only had to repalce 2 gallons of oil after getting storm debri cleaned up once the cyl started leaking again.
all stop leak does is usually swell seals.. and it's not permanent.. and sometimes the cost is they become soft, and wear evenmore... so it's deffinately a bandaid, at best.
I'd get it fixed correctly..

well yeah but money is tight as usual and the part is 67$
at best and Thats the cheap one. so that's why i was wondering if it was possible to use that to temporarily fix it for now.????

what kind of fluid does that cyl call for?
find a stop leak product made for that application.
at this point.. if money's tight, you are only gonna be out the cost of the fluid in the system, when you finally can change it.
good luck. hopefully you can find something to work for ya and get some months out of the temp fix.
BTDT and wish you well.

it uses DOT 3 or 4 Brake Fluid. which one is the thicker fluid? i might try using a thicker fluid till i can get it fixed.

that's what I feared... since it is a brake fluid system.. there really aren't any stop leak products for it...

I've used Lucas power steering stop leak a number of times. Got a Nissan I put some in 6 years ago and it's still going and no leaks. Got a 87 Ford F250 that I put it in 3 years ago and it's doing fine.
The Lucas hydraulic stop leak will work but if you put to much the seals will turn to mush. My tractor dealer showed me one that some one thought more was better. But it will stop most leaks.

I have a 72 Plymouth with a leaky Power Steering Pump that I would have to add fluid each week...
I put in stop leak and it has been 17 years without having to add anymore fluid...

What I'd do is read the directions and I think it'll tell you how much to add per gal. or 5 gal. of hydraulic oil. I'd add about half of what's call for and if it doesn't stop the leak I'd continue to add till the leak stops or you reach what is recommended by the directions.
And in case there's some confusion, Lucas makes 2 stop leak products. One is for power steering and the other is for hydraulic systems. And as stated by others I wouldn't use it if there are wet clutches and electronic shifting in the system. I would consider it on some of the older tractors that just had a set of remotes and wet brakes.

Yes, I've used the Lucas PS Stop Leak in my car, but eventually had to fix the real problem, pinholes in the rusted steel lines on the steering rack. This stuff rejuvenates hard, worn seals and is also very viscous, like STP, so it takes a lot longer to leak out.
