Lucas Oil10019 Hydraulic Oil Booster and Stop Leak - 1 Quart, White, 32 Ounce

My Kubota bucket rams were starting to leak after 650 hours. Same for the stabilizers on the backhoe. One bottle in the tractor and one in the backhoe. Almost fixed instantly. Absolutely no leaks after 3 months. The viscosity reminds me of STP Oil treatment for you old timers like myself.

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.

I used this in my convertible cylinder of my 2002 mustang. 2 weeks later it's still mildly leaking but because of all the positive reviews I'm thinking it's just too big of a leak and I will need to replace the part. It did however slow the leak significantly so for that I'm grateful.

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.

Sealed iit without using the whole bottle.

I have a 1949 Ford 8N tractor that I recently purchased. The hydraulics indicated that work might have to be performed--when I would raise the drawbar and park the tractor, the drawbar would sag within hours. So I decided to use this Lucas product. I siphoned off approximately 1 quart of the tractor's hydraulic fluid, and replaced with an equal amount of this, then operated the tractor for about half an hour to exercise it. I fully raised the drawbar and then shut the ignition off. 6 days later, the drawbar dropped very gradually, but it's still off the ground amazingly, and this has been in spite of with daytime temperatures below freezing, and night-time temperatures in the teens (the tractor sits outdoors). Needless to say, the results with this modest experiment speak for themselves!So I'm impressed--I could've easily paid a mechanic several hundred dollars to overhaul the hydraulics and I might've seen results that I have now. It's no replacement for a rebuild to spec, but could be enough to get you more use out of older equipment.

My trim was leaking at the shaft seal. I put a few squirts if it in with the hydraulic fluid and a bit on top. Within a few tries it seemed like it was going way higher than before and leaking wayyy less. I’m hoping it lasts. Time will tell. Btw. This is on a 2000 Johnson outboard 50hp boat motor.Day 2 it was still leaking but not as much. I'm going to add some more today and check fluid level. It's tilting down way better but still struggling (although less) when I bring the motor up.Day 3 again leaking a little less each day. I haven't been out on the water yet but it seems to be holding up wayy better. I went to fill the resevoir yesterday and there was still fluid in there. Barely needed extra. I read that it can take time to fully resolve leaks. I'm optimistic.UPDATE: After being on the water for a few days, the trim did work better BUT it seems to have sprung a new leak potentially. I have to replace the seals after all. Disappointed.
