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.

Thanks for making such a GREAT product! It sure saved me a lot of cash!

I am a salesman who puts a lot of miles, a mixture of highway and city stop and go, on vehicles. I currently own a 2005 Toyota Camry with 205,000 miles on it's 4 cylinder engine. About two months ago I started noticing a puff of smoke on the first start up of the day. It kept getting progressively worse, so I spoke to a mechanic who told me the valve seals were shot. Cost of repairing the seals wouldn't be that much more than replacing the engine with a used one. The engine was not leaking oil on the garage floor and it runs really well, so I started looking for an alternative. On the advice of another mechanic I picked up an additive from a well known company. It didn't come close to slowing down what had become a pretty significant cloud. I didn't want to spend $3500 on a car with that amount of miles and decided to give it one more shot, I've used a variety of Lucas products and have always been pleased with the results. Changed the oil using one of the best synthetic oils you can buy and substituted a quart of Engine Oil Stop Leak. On the bottle you state "It Works" and I am living proof that it does exactly that. On the very first start up the next morning NO SMOKE! Not only that, but the engine runs smoother and much quieter. Thanks for making such a GREAT product! It sure saved me a lot of cash!

I used the stop leak in a 23 hp Kawasaki and it stopped the leak 100%.

I have used Lucas products for many years in my vehicles and small engines in my lawn business. Its hard to believe it works but it really does. I used the stop leak in a 23 hp Kawasaki and it stopped the leak 100%. I use the stabilizer in everything. I recently changed oil in a commercial hand mower and didnt have any Lucas so I didnt use it. After 5 min the engine started knocking (never heard it before) I then changed oil again adding Lucas and the knock is gone completley. Lucas will always go in all of my engines, Great product.

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!

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!
