HEAR IT FROM OUR CUSTOMERS

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.

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!!

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.

I am amazed! This product works!!

First of all, I don't typically writes reviews or testimonials, but I can't keep this to myself. Background: 2005 Chevy Suburban 1500 (8cyl, Vortec 5.3). 235k miles. A horse! Rear main seal leak for about this last 12-18 months. Recently developed a front seal (crankshaft) leak that was making a mess under the hood (oil spray) and stinking up the garage (oil burning off hot block). I'm thinking its time to replace the front seal, harmonic, etc. My mechanic recommended giving LUCAS ENGINE OIL STOP LEAK a try. So I did. Drained the oil, changed the filter, and filled her up with 5 qts synthetic + 1 qt LUCAS ENGINE OIL STOP LEAK. I figured it might slow the leak, especially with the weather getting colder. Well ... Day 2 and NOT A DROP. Zero. Zip. Zilch. The leaks - both front and rear - have stopped. Not to mention, the engine feels better than it was for awhile. I had some occasional valve-lifter tapping. Gone. She purrs on idle and has improved acceleration. I am amazed! I guess I need to wait and see how long the good news lasts, but for the time being ... This product works!! Try it before you spend a few hundred bucks or half your day. Rock on!

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!
