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 far100 miles - oil puddle smaller500 miles - leak stopped temporarily600 miles - leak started again but smaller puddle1200 miles - leaked stopped again1500 miles - still no leaking, oil level still fineSo far i'm pretty impressed. Will revise to 5 stars if no leaking for another 1,000 miles

At the ripe old age of my vehicle, one tends to leak a little but not any more with this Lucas Stop Leak.

My slow oil leak seems to have been corrected. My engine runs quieter. It was well worth it. Easy to use with no smell or fuss. Note: my car is a 2013 model with 160k miles on it.

Didn't seal but slowed down leaks, I may try have to try a 2nd treat hope it can stop.

My 2009 Ford Escape had been leaking oil for a few months. Just a few drips each day. After using this product, the drips went away after about week. It has been a month and everything is looking good so far.
