  • “You people are geniuses! Over the years, I have used your various products with 100% success! I had a floor jack that "died" and was going to put it out for the trash. BUT, I saw your floor jack "fix it in a bottle" and tried it. Still batting 100%! Since I am in my mid-fifties, do you have anything that stops memory leaks?”

  • “I have used this product on my snowplows (I have two) and each time it repaired the small hydraulic leaks and conditioned the plows for yet another season. I know these will die eventually but so far this product has kept me going two seasons past what I expected. Thanks you guys have saved me a lot of money.”

  • “This stuff works! I loaned a floor jack to a friend who didn't take care of it. When he returned it the carrying case was broke and the jack was leaking. I continued to use it for a period of time before it would not raise past half height, making it almost useless. I was about to throw it away but bought this product while out one day. I drained the remainder of the old fluid and replaced it with Bar's Leaks Jack Oil with Stop Leak. The jack works perfectly again. Thanks for saving me about $100 bucks for a new jack!”
