1 Quart of Lucas Engine Oil Stop Leak Saves $7,000

I had an internal oil leak on my 2005 Jeep Grand Cherokee. Dealer wanted to charge me $7,000 for a new engine. 1 quart of Lucas Engine Oil Stop Leak fixed the problem. Jeep is fine now 180,000 miles and counting!

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.

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!!

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.
