HEAR IT FROM OUR CUSTOMERS

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!

Lucas Engine Oil Stop Leak “Just Works” for Avalanche’s Start Up Problems

I have a 2004 Avalanche with 170k miles. After longish trips (100+miles) the next start up would bring a cloud of smoke. I added the Engine Oil Leak Stop and it worked almost immediately. Also, compression is noticeably higher and the engine runs much smoother. It just works.

One treatment with a quart of Lucas Stop Leak and has eliminated about 90% of fouling…

My sweet running 1996 Roadmaster with 230,000 miles on the odometer had started fouling spark plugs due to warn valve stem seals....one treatment with a quart of Lucas Stop Leak and has eliminated about 90% of fouling after running motor 1400 miles....I'm very happy with this product and will use it at every oil change from now on!.....It's a lot cheaper and better than repairs or changing plugs every 1000 miles or so.

Lisa saved $1200 by using Lucas Engine Oil Stop Leak.

I cannot say enough positive things about the Lucas Oil leak product. My daughters 2004 Honda Civic developed an oil leak. We were told it was a head gasket with a repair cost of $1200! A friend recommended the Lucas product so what did we have to loose. After getting an oil change and having them put 1qt of the Lucas product in (Follow directions on the bottle) we waited to see if this would solve the problem. After about driving the car for about 200 miles the leak disappeared no more oil spots on the driveway! The engine is running smoothly and no more leak. Thank you Lucas Oil!!!

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!
