No More White Smoke, No More Oil Burn!! Works as Advertised!!

My 2006 Chevy Silverado developed a valve seal leak do to my improper maintenance practice at the time... There would be a puff of white smoke out the tail pipe every few mornings when I'd start my truck from oil seeping into the combustion chamber. I put Lucas Engine Oil Stop Leak in. After a few days like the bottle says, no more white smoke, no more oil burn!! Works as advertised!!

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 added Lucas Oil Stop Leak about a month ago and what a difference!

I have a 2004 chevy cavalier with 304,000 miles which is my work car. I usually have to add 1 quart of oil every 2 weeks. I commute 80 miles a day back and forth to work. I added Lucas Oil Stop Leak about a month ago and what a difference! I have only needed to add a half of a quart oil since adding that. I will continue to use the Engine Oil Stop Leak with every oil change from now on!! AWESOME PRODUCTS!!! Tested, proven, and effective!!

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.

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!
