Picked up a bottle of Lucas Stop Leak…and the problem was solved!

My Kubota Tractor had a Transmission Seal that began to leak. Within a few months it began leaking badly. Contacted Kubota Service Department and was told $1,000.00 to split tractor and replace seal. Picked up a bottle of Lucas Stop Leak.......and the problem was solved! Thank You Lucas!

Thanks for great products that actually work as advertised!

I use Lucas oils and additives in all of my personal cars. As a heavy equipment mechanic, I recently tried your Engine Oil Stop Leak on a leaky rear main in a 33k forklift. Worked like a charm! Saved me huge hassle, and the company saved big bucks. Thanks for great products that actually work as advertised! P.s. your Extreme Duty Gun Oil is the best on the market.

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 believe 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.

The leak was gone and it works.

I drive a 2008 Hummer H3 Alpha with 127,000 and I have noticed that I was leaking a little oil in my garage. I bought a bottle of Lucas Oil Stop and within 3 hours after driving her for 30 minutes the leak was gone and it works.

After a week it has stopped dripping!

Got a 2002 f150 4.2 for my wife. It had 20800 miles on it and was a one owner in really good shape. Except when got it home there was oil leaking under it. Locked like rear main seal. Change oil and filter and put some of that Blue rear main sealer in it. Dove it like they said and it did not help. Was dripping ever time she came home. So I was about to spend a lot of money to replace the rear seal. But said I will try the Lucas oil stop leak before spending a lot of money on it. After the first day it slowed down the drip and after a week it has stopped dripping. Yes it still used a little oil but it is a old truck with a lot of miles. It has been about 5 weeks now and no drip in the carport. How long it will work I don't know. But for me it did a great job. Yes I would say try it if you have a leak. Best $14 I spent in along time.
