  • Works great. Does more than seal nasty leaks.
Style: Engine Oil
I've tried many other oil leak sealers over the years for automobile engines, but this one actually works. Funny thing is, that immediately after I added it to my 2002 2.4L LD9 engine, the motor suddenly ran smoother and quieter than it ever has! Other people noticed, too. I there magic involved here somehow??? 1,000 miles later, it's still doing everything and more than is claimed on the label. And it sosts less than most. ... show more

  • Didnt notice a big difference
Style: Engine Oil
I had the gaskets replaced around 4 months ago and my engine is dripping little oil, tried the treatment, ran for 300 miles, then again for 100 checked oil and was low again, Its not big leak, but after a week you can notice a small puddle in the driveway. Burnt oil smell went away Maybe a second bottle is needed. Keeping my hopes up. Dont want to dismantle the whole engine to find a gasket that was incorrectly seated. ... show more
