Review: Works great. Does more than seal nasty leaks. - 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.
Review: Just what I needed. - Working for me.
