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.

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.

One treatment with a quart of Lucas Stop Leak and has eliminated about 90% of fouling…

My sweet running 1996 Roadmaster with 230,000 miles on the odometer had started fouling spark plugs due to warn valve stem seals....one treatment with a quart of Lucas Stop Leak and has eliminated about 90% of fouling after running motor 1400 miles....I'm very happy with this product and will use it at every oil change from now on!.....It's a lot cheaper and better than repairs or changing plugs every 1000 miles or so.

I would highly recommend it.

I have a 2007 Suzuki SX4, 150,000 miles. It stared leaking oil, leaving quite a puddle of oil on my new concrete, I tried Lucas Engine Oil Stop Leak, very pleased. It stopped most of the leak I'm going to put more in. I would highly recommend it. Thanks Lucas Oil.

The leak had disappeared completely in a matter of days.

I have a 1987 Ford F150 with over 260k miles. It developed a rear main seal leak and not worth the money to have it replaced on a vehicle this old. Put the whole bottle of Lucas Oil Stop Leak in my next oil change and the leak had disappeared completely in a matter of days. The truck is also running smoother and the inline 6 engine sounds better than it did before.
