Bar's Leaks Jack Oil with Stop Leak - 12.5 oz

This works great. Had a slow leak in a floor jack, easy to use bottle, remove the seal from under the cap, clip the cap and pour. Haven’t noticed any drips from my floor jack since using it.

Worked well to refill a pallet jack and a floor jack. Very happy with its actions to slow down a leak on the pallet jack shaft. Overall I would recommend this product but don't expect miracles of its stop leak ability.

Good stuff. I needed to refill a torin 20 ton bottle jack I got for my truck. It barely lifted. All the fluid had leaked out in transit and it lasted long enough for a job or two. It was a pricy jack so I figured I should refill it vs get a new one. This stuff works and it's cheapish. My only complaint is the lack of a resealable bottle as I could use it for other jacks as well.

it's hydraulic oil. . . what else can i say? My bottle arrive missing the red plastic cap, so i've subtract one star. I will pour the oil into a 12oz condiment squirt bottle which has a cap. cheers.

My floor jack wasn’t working as it had to so I ordered this via Prime. It arrived quickly and was sealed to protect against leakage. Once unboxed and opened, the easy pour tip fit well into the small fill hole found at the top of the jack. The product didn’t smell strong and works quite well. I would easily buy this again and recommend it to others looking for an easy update to help make their jacks work like new once again.

This oil worked great in my harbor freight jack. O rings were getting bad and this helped restore the functionality of my jack that I thought I might have to replace.

This jack stand oil works as designed.

The clutch master cylinder failed on my 2012 Ford Focus. It leaked internally, causing the pedal to sink to the floor without disengaging the clutch, but with no loss of brake fluid. The same reservoir is used on the Focus to hold fluid for the brakes and the clutch. Bars Leaks jack oil with stop leak must NOT be put into the brake system reservoir because it can affect the boiling point of brake fluid and the viscosity thereby causing problems with the ABS system. Also, it will not mix with brake fluid. My solution was to segregate the clutch hydraulics from the brake system. I purchased from Amazon a Lefossi universal reservoir for motorcycle brake systems. I mounted this reservoir on the side of the battery box. I also bought from Amazon some 150 cc plastic syringes for fluid transfer. I cut the fluid line from the brake master cylinder reservoir to the clutch master cylinder fluid intake nipple. I plugged the output nipple on the brake master cylinder reservoir. I ran a hose from the remaining section of the fluid supply line to the clutch master cylinder up to the Lefossi reservoir. I then vacuumed out the remaining residual brake fluid in the clutch system using a manual brake vacuum pump which can be purchased from Amazon, by connecting the vacuum pump to the clutch bleed nipple. After that, I used the syringe to pump the Bars Leak jack fluid into the clutch bleed nipple. This filled the clutch hydraulic system and automatically bled the system of all air. I pumped in just enough jack fluid to fill the Lefossi reservoir (this is called reverse injection). Then I closed the clutch bleed nipple. The result, it took about 15 hours or so for the Bars Leak jack oil to do its magic and then the clutch worked perfectly! Bars company claims you should allow up to 3 days for the oil to recondition the seals of a hydraulic jack or snow plow system. They also insist that there are no solvents in the product which can ultimately dissolve the seals. Bars company does not specifically recommend the jack oil for use in clutch systems, and they caution against putting this stuff into the brake fluid in the brake reservoir. It can ruin your brakes, but I got great results with my clutch system after I segregated the brake hydraulics from the clutch hydraulics, and I saved almost $500!
