HEAR IT FROM OUR CUSTOMERS

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 noticed a difference almost instantly.

Last month I purchased a used Ford Explorer off a friend who was moving. I did my own regular routine maintenance fixing this, replacing that. Well being an older vehicle I decide to use your Engine Oil Stop leak for the first time ever in the crankcase. Now I was expecting a slight difference or improvement but instead I noticed a difference almost instantly. The way the vehicle turned over and then idled. I wouldn’t have called the vehicle noisy in the first place but I had to double check to see if the vehicle was actually on and the oil pressure gauge to my excitement slowly started to climb. I have always used your products in the past and will continue to do so Canada loves Lucas!

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.

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!

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!
