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 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!

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!

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!!

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!
