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.

Oil usage and smoking
Works great I have a 2004 Dodge ram 315000 miles was burning a quart of oil around every week and smoked a little sometimes. Added a quart of Lucas engine oil stop leak in a out 4 weeks it stopped burning oil and smoking..... working great for me

Seems to be working
Put in half a quart (you can always add more but you cant take it out) to see what happened to a 2014 Subaru Outback 2.5L with 108k. Three oil leaks diagnosed by dealer as upper oil pan, lower oil pan and cam carrier seal. Was quoted $4,500 plus tax for engine removal and full engine reseal. Oil was dripping after stopping driving maybe one drop per second for 5-10 minutes after the recent oil change when the dealer saw the leak . Was not sure this would work since since the upper oil pan and cam carrier seal are a silicon tooth paste like sealant. Story so far 100 miles - oil puddle smaller 500 miles - leak stopped temporarily 600 miles - leak started again but smaller puddle 1200 miles - leaked stopped again 1500 miles - still no leaking, oil level still fine So far i'm pretty impressed. Will revise to 5 stars if no leaking for another 1,000 miles

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!

Did not stop my leak but definitely not a bad additive to my f150 5.0 with 350k on the clock

It says China as the country of origin, but Lucas is made 100% in the USA. Is this a counterfeit copy? Used 1qt. no real difference in oil leak.
