Lucas Oil Products LUC10278 Engine Oil Stop Leak, 1 Quart, 1 Pack

Stopped the leak as advertised.

Excelente

I normally dont write reviews but I needed to on this Lucas product. I never have any luck with stop leak anything, but I've used Lucas oil stabilizer for years and have always liked their products. This year I tried their stop oil leak product on my old Ford truck. It has a 460cid motor with 170k miles on it. It's all stock no major work done to it. It had a major oil leak from the rear main seal, and I'm to lazy to do all the work to change the seal. So I tried the stop leak and it to my surprise it stopped the leak 100% no bs. I couldn't believe it so I tried it in my Mini Cooper as well. It has well over 200k and leaked a lot of oil. I'm not sure where the leak is, so on my last oil change I added the stop leak. It reduced the leak 95% it could be a 100% and the few drips may be left over oil on the chassis. I totally recommend Lucas stop oil leak! Actually all the Lucas oil products are second to none.

Works ok still have a minor leak

I'm not one to write many reviews, but I had to give a shout out to Lucas Oil Stop Leak.I inherited a 2002 Saturn SL Sedan with 220k miles that leaked considerable oil on my driveway. I replaced the valve cover gasket, which was some of the problem. But, the front main seal and the oil pan were both leaking significantly. The car just isn't worth lifting the motor out to replace those seals.So, I bought the Lucas oil stop leak not expecting much. I would have been happy if it just slowed the leak rate a little. But to my surprise, it stopped the oil leaks completely in about 100 miles driving.Thank you Lucas Oil Stop Leak! Best money I have spent in a long time!

Used this product before, works well.

I have a 2001 Camry V6, which is known for some leaky gaskets. When it developed a leak around the oil pan, I used generous amounts of JB weld and a bottle of some generic leak stop dluid to give it a few more months on life before junking it. That helped a bit, but when the leaks came back, half of this bottle stops leaks for 2 months at a time. If you just need to buy a few months before a proper service or putting the car out to pasture, this does the trick!

I have a 1999 Camry with a little over 200,000 miles on it and it eats up a quart of oil every thousand miles. With my job I’m adding a quart a week to maintain the engine. I’ve had two different mechanics shops recommended this product so I figured I’d give it a try. This engine is extremely weak and when you floor it I can only describe the sound as someone decided to build a giant whoopee cushion out of sheet metal. My exhaust system has minimal rust and no leaks so it’s all engine noise. Right after I poured this stuff in and went for a drive the engine sound changed to a completely different tone. It’s a low growl like when your muffler falls off. I’m not noticing anything better or worse performance wise so I’m not even sure what it did. 🤷‍♂️
