Works
Went from few drops out the valve cover to no drops. Took about a week and a oil change with another bottle of oil seal but it worked

Lucas stop leak "WORKS"
I was skeptical at first but it did stop my engine leak. I used have to add a quart every two to three weeks I haven't added "any" oil in a month as my dipstick still shows full. I use all Lucas products to maintain my vehicle. Try it and you'll agree.

Run the engine hot . The sooner the better.
It stopped the leak. No ifs ands or buts. Does what it says. Just hesitant to call it good.

Works Great!!
Installed a new filter (because I just did a oil change 700 miles previously) added this and Wow it works , The reason I used this is my mechanic said I had a small oil leak , my car actually runs smoother!
