Don’t hesitate just buy it.

I had a Chevy Suburban with a hundred and 180 K miles with a rear main seal leak... Added Lucas Stop Leak and now have 302,000 no leaks. 40psi at idle. Best stuff I have ever used!! I use the truck to plow and pull car trailers. I'm going to hook my camper up to it in June and take it on a 4 hour trip. Lucas is the best. One quart of every oil change in my 5.3 Chevy V8. Don't hesitate just buy it.

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!

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.

Thanks for making such a GREAT product! It sure saved me a lot of cash!

I am a salesman who puts a lot of miles, a mixture of highway and city stop and go, on vehicles. I currently own a 2005 Toyota Camry with 205,000 miles on it's 4 cylinder engine. About two months ago I started noticing a puff of smoke on the first start up of the day. It kept getting progressively worse, so I spoke to a mechanic who told me the valve seals were shot. Cost of repairing the seals wouldn't be that much more than replacing the engine with a used one. The engine was not leaking oil on the garage floor and it runs really well, so I started looking for an alternative. On the advice of another mechanic I picked up an additive from a well known company. It didn't come close to slowing down what had become a pretty significant cloud. I didn't want to spend $3500 on a car with that amount of miles and decided to give it one more shot, I've used a variety of Lucas products and have always been pleased with the results. Changed the oil using one of the best synthetic oils you can buy and substituted a quart of Engine Oil Stop Leak. On the bottle you state "It Works" and I am living proof that it does exactly that. On the very first start up the next morning NO SMOKE! Not only that, but the engine runs smoother and much quieter. Thanks for making such a GREAT product! It sure saved me a lot of cash!

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.
