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.

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.

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.

This stuff is amazing. Will be adding a quart with every oil change.

I’ve got a 2005 GMC Savannah with almost 300k. Started using alot of oil. Needed a liter every 500km. The oil pressure would drop so low at idle that the light came on. 3 min after adding a bottle of this Engine Magic you call Stop Leak and my oil pressure is right back to where it should be. This stuff is amazing. Will be adding a quart with every oil change.
