    Rated 5 out of 5 by from It really stopped oil leakage I read about these products and my car left more than a few drops of oil on the garage floor each day so I checked this one. The good reviews weren't lying, this product worked perfectly. It's well worth using it.

    Rated 5 out of 5 by from Oil leak on BMW e46 This is a great product and well worth a try. I had an oil leak on my BMW e46. these cars are well know for engine oil leaks. I added this to my engine oil and about 2 weeks later the leak seems to have stopped. Its saved me a the cost and inconvenience of going to a garage. Would recommend to anyone.

    Rated 5 out of 5 by from Brilliant This product was recommended by a man who knows alot about cars said my oil leak was probably due to a worn seal. The part to replace was a few pounds but because of the position of the leak the labour cost would be huge. I decided that £6 was worth a shot and so far so good. No more oil drips on my drive. Give it a go....

    Rated 4 out of 5 by from wynns engine stop leak,good features I bought this as a precaution my car is 14yrs old and thought it a good idea to revamp the rubber seals so I cant actually tell if it worked or not because I had no leak to start with

    Rated 5 out of 5 by from Seems to have done the job. After my MOT the garage told me there was an oil leak but they couldn't determine where as it wasn't a lot and they didn't have time to start taking things apart while telling me it was up to me to decide if a repair would be done. Read about this stuff, tried it and can't detect a leak after a month of driving around. NOT losing oil, NOT leaving oil under the car either. Must've done the job.

    Rated 1 out of 5 by from Didn't do what it suggests I only had a small drip and this stuff was meant to cure it. The leak has got no better or worse. Waste of money for me.

    Rated 5 out of 5 by from Engine stop leak does work. It has slowed down the leak in my engine. The leak is to big for engine stop leak, instead Engine stop leak does work. It has slowed down the leak in my engine. The leak is to big for engine stop leak to work effective , instead of drops of oil gathering. The oil is now like a thin film of oil on engine so it has nearly stopped the leak. I think the seals are worn past repair. Hope this helps.
