HEAR IT FROM OUR CUSTOMERS

I am now a devoted Lucas fan. Thanks for saving me $$$$$!

I have a 2004 Monte Carlo Supercharged SS with 138,000kms which I just took in for an oil change. Upon completion, I was shocked to see the report: Oil pan gasket leak, Rear main seal, Both valve covers, Oil pan drain plug, Front cover gasket and Front crank seal. So while engine shopping I learned about this Lucas Oil product [Engine Oil Stop Leak]. I decided to try two bottles to try evaluate any improvements as $24 Cdn is much less than an engine. Three days later, after one quart of Lucas and miraculously my engine has healed it’s weary self and performs like new! Not a drop of leakage! I am now a devoted Lucas fan. Thanks for saving me $$$$$ ! Cheers from Canada!

Results were apparent the first day…

I have an old 8000 lb fork lift with a 3-stage mast. It was leaking like a sieve. I would keep a pan under it and dump the hydraulic oil back in through a filter every time I wanted to use it. I was expecting to pay more than $1000 to replace the seals. A guy at a local autoparts store recommended Lucas Hydraulic Oil Booster and Stop Leak. I dumped in an entire bottle. The reservoir holds more than 5 gallons. Results were apparent the first day and they have been even better since. We used to have to dump a trail of cat litter to soak up the trail of hydraulic oil. Now there is zero trail. It's great stuff!

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.

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.

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.
