I used the stop leak in a 23 hp Kawasaki and it stopped the leak 100%.

I have used Lucas products for many years in my vehicles and small engines in my lawn business. Its hard to beleive it works but it really does. I used the stop leak in a 23 hp Kawasaki and it stopped the leak 100%. I use the stabilizer in everything. I recently changed oil in a commercial hand mower and didnt have any Lucas so I didnt use it. After 5 min the engine started knocking (never heard it before) I then changed oil again adding Lucas and the knock is gone completley. Lucas will always go in all of my engines, Great product.
