HEAR IT FROM OUR CUSTOMERS

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.

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.

Thanks for great products that actually work as advertised!

I use Lucas oils and additives in all of my personal cars. As a heavy equipment mechanic, I recently tried your Engine Oil Stop Leak on a leaky rear main in a 33k forklift. Worked like a charm! Saved me huge hassle, and the company saved big bucks. Thanks for great products that actually work as advertised! P.s. your Extreme Duty Gun Oil is the best on the market.

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!

I could feel the engine running smoother than before and the leak also stopped.

My 2001 Honda Accord had been having small leak issue, which the dealer recommended having the O-ring on distributor replaced to stop the leak, but the leak persisted. I previously used Lucas Oil for my transmission before and it worked great, so I decided to try this $9 method before doing anything else. After the first bottle about 5 months ago, I could feel the engine running smoother than before and the leak also stopped. Obviously I got a second bottle to use at my next oil change interval which was two months ago and had not have any problem since. Since my car is 17 years old, I will certainly use this product at every other oil change interval from now on. I would rather pay an extra $9 at every other oil change interval (or at least once a year) as a preventive maintenance method than end up spending hundreds if not thousands of dollars to replace the seals later, especially the temperature where I live at times can fluctuate as much as 40 degrees within a day. Thank you again Lucas!
