It worked for me.
Had a couple small leaks on 2008 Outback so I gave this stuff a try. Slowed them immediately, full stop after 300 miles.

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

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

Oil usage and smoking

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.
