HEAR IT FROM OUR CUSTOMERS

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.

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.

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!

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.

I noticed a difference almost instantly.

Last month I purchased a used Ford Explorer off a friend who was moving. I did my own regular routine maintenance fixing this, replacing that. Well being an older vehicle I decide to use your Engine Oil Stop leak for the first time ever in the crankcase. Now I was expecting a slight difference or improvement but instead I noticed a difference almost instantly. The way the vehicle turned over and then idled. I wouldn’t have called the vehicle noisy in the first place but I had to double check to see if the vehicle was actually on and the oil pressure gauge to my excitement slowly started to climb. I have always used your products in the past and will continue to do so Canada loves Lucas!
