10278 Engine Stop Leak, 946 ml

Very effectively stopped a worn engine from consuming lots of oil. Very happy.

Had a very small oil leak from a Valve Cover on a BMW, that just would not seal at all no matter what, even after gasket replacement. Gave this a try and within 20 miles no leak, no burning oil smell and no drips onto the Manifold. Was very surprised as most of these products never work, but this did. Great product, would use agin.

Didn't think this would work ha e Mercedes gla45amg and notice a oil leak underneath which would probably have cost me hundreds to repair gave this a try and to my amazement it worked gave it a few weeks it started to get smaller then completely has disappeared so highly recommend this product 😀

After 300k miles, the car has a suspect oil leak (probably the turbo bearing seals) and to make matters worse, on a recent oil change I put in a slightly thinner grade of oil than I should. Used various Lucas products in the past (the fuel saver is really good, as is the oil stabiliser) and decided to get a bottle of stop leak and add a little to thicken the oil. Slight engine rattle disappeared immediately. If there is a persistent slight oil leak, given my experience with other lucas products - I have the utmost confidence that it will slow it down as I add more when and if there's room to.

This stuff looks like Golden syrup or honey mixed with a glue but obviously it is not this. it is proper oil and mineral based product just very viscous. Followed the instructions and so far I am pleasantly surprised. The annoying leak has stopped, need to put some serious hot driving in and see if I still leave a small puddle in the works carpark. My advice to make use easier - it is better if the outside temp is not close to freezing, the colder the temp the thicker the unmixed product the harder to pour. Update after 600 miles, has reduced the leak but not by much, obviously it cannot work for all leaks.

Amazing no more leak

I had a major leak, added 1 liter to 3 liter oil , It changes the sound of engine it is smoother now, I am really surprised.It didnt help with the leak though. I don't know what could be the long term consequences but for the beginning I am happywith it.

This works really well on older cars where you may have a small oil drip here and there. Also quietens the engine. A good proven product

Mix in juiste ratio

Sticky stuff works great definitely recommend for minor leaks

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.
