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.

I noticed a difference almost instantly.

Last month I purchased a used Ford Explorer off a friend who was moving. I did my own regular routine maintenance fixing this, replacing that. Well being an older vehicle I decide to use your Engine Oil Stop leak for the first time ever in the crankcase. Now I was expecting a slight difference or improvement but instead I noticed a difference almost instantly. The way the vehicle turned over and then idled. I wouldn’t have called the vehicle noisy in the first place but I had to double check to see if the vehicle was actually on and the oil pressure gauge to my excitement slowly started to climb. I have always used your products in the past and will continue to do so Canada loves Lucas!

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!

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.

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.
