11100 Engine Oil Stop Leak - Top Off Additive - 1 Quart

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.

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

awsome stuff

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

Massive oil leak, but engine has lots of miles so I tried this. And it worked.

Did exactly what it says

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

Outstanding

Works exactly as advertised and as expected considering the severity of the leak. Had to keep topping up until the overall mass of the oil in engine pan had taken on the thicker viscosity and then the issue was addressed.

works great

Oil leaking has stopped! Good product!

Vary good oil helped lots.

Not impresss with the oil never sealed my leak
