Lucas Oil 10278 Engine Oil Stop Leak - 1 Quart

Just purchased a used 2009 Mini Cooper S, and discovered that they have a history of oil leaks, and seal issues.I put this product into my initial oil change, and crossed my fingers. . . .hoping it would help! Now, after a few hundred miles of local trips, and after purchasing a galvanized drip pan, to keep my garage floor clean, I first noticed a few oil drips in my pan, after some local trips, but now. . . . . . . that pan is spotless! No drips!! No leaks, as before, under the oil filter area!!Looks like this stuff works!! Give it a try!

The rear main seal was leaking on my Z71. I added a quart of this stop leak and it greatly reduced the oil leak.

I have used this for years. It does an excellent job. The larger size makes it very cost effective.

Works good stop almost all the leak just a small drop once in a while now.

2016 Kia Sorento 2.4 L developed an oil leak at 92K.After investigating all the products to stop the leak, I chose Lucas. This product worked for me. It is currently in my engine now and I’ve driven about 800 miles on this oil. No more leak. I like this product and would use it again.

Excellent as always can't beat Lucas

My daily beater commuter car developed a leak at the rear main seal. Mechanic quoted a grand to fix. There's no way I was going to pay that but the leak was pretty embarrassing. I figured what the heck. I'll try this mechanic in a bottle because why not lol. My gnarly leak completely disappeared within 2 days. I can actually park in my driveway again. Holy crap. Who knows how long this will last. At the very least it bought me time. I will be adding a quart of this into every oil change.

Used this product before, works well.
