Lucas Oil 10279 Engine Oil Stop Leak - 1 Gallon

Sticky stuff works great definitely recommend for minor leaks

This product has been negatively reviewed far too many times, and I felt compelled to write a review on it. I have used this product on 3 cars with oil leaks, and my family has used it on their cars as well. My family has had great success with minor oil leaks, and 2 of my 3 cars I have used this on resulted in their oil leaks ceasing completely. My other car turned out to be a decent sized crack in my oil pan gasket, which explains why throwing some Stop Leak at it didn't solve my issue. This product helps greatly to repair old, hardened seals, but it doesn't falsely advertise to bring about miraculous results in moderate to major issues. My point is, this product works extremely well for it's intended purposes, and I feel that all of the negative reviews should be taken with an grain of salt. It would be spectacular to hear, from the negative reviewers, what sort of issues ended up being diagnosed in the cars this product didn't help. I'm by no means trying to put down the negative reviewers, but it does get a bit frustrating reading reviews on Amazon like "Put it in my car, didn't work, still leaking, crap product" or "I contracted a flesh-eating bacteria, and this 'highly rated' Neosporin didn't work. Don't waste your time. 1 star. Booooooo!!!!" Lucas Stop Leak is a great product for it's intended purposes, has been used and trusted by amateur and professional mechanics for years, and fully deserves a solid 5 stars.

I have a leaking intake manifold gasket and the engine needs to be removed to replace and the car has over 200,000 miles on it. Works better that it is warmer which I believe improves the viscosity of oil but it will never stop leaking. I'll let the next person decide what to do because I upgraded to a newer year and model. And, yes, to be sure, I will express all that my older car needs when I sell. The good thing is that I have maintained well enough that it will pass inspection and that was always the case. Don't know why I am shaking this but it's my post so there we are...LOL

I have a 2016 international prostar with a cummings engine ixs. It had a front engine seal leak. I added this at my last oil change. It took about two weeks and it stopped leaking oil. Yes I was surprised because I added only one gallon, not to mention that I really didn't think it would work. My leak was so bad it was oil was blowing on my right steer brake, this has save me some time.I have 960000 miles on my engine, trying to hold out until a rebuild .

I used this in my Honda with over 325,000 miles, and it’s been a good addition. It helped reduce minor oil seepage and gave me some peace of mind with an older engine. Easy to pour in and didn’t cause any issues. For high-mileage vehicles that are still running strong, this is a solid product to try.

I can't believe how this worked. I used this in my lawnmower that leaked a small puddle of oil every time I used it. Now not a drop. Best money I've spent in a long time.

My wife's expedition had a small leak coming from the oil pan for a few years. I got tired of seeing small speck of oil so I decided to try Lucas, low and behold after driving the car for 2 weeks the leaks disappeared. The trick is to drive the car at least 200 miles for the additive to work.

I have used a couple Lucas products in the past that have been almost miracles. Transmission Fix and Power Steering Stop Leak saved me thousands of dollars in repairs. This didn't live up to their other products, but the issue is probably my 190K engine and not the product.

I had a very slight oil leak and this product solved the issue after a couple of days of driving. It's not a permanent solution but so far no more leaking. Not sure how this would perform on more serious leaks.

Sehr gut

I own an old car and this oil stopped my leaking. Amazing
