    Rated 5 out of 5 by 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. 13 August 2016
    Rated 1 out of 5 by Didn't work Tried this product on my oil leak and didn't work atall leak is still exsactly the same and don't fancy buying another can to try again tbh 30 July 2016
    Rated 5 out of 5 by Buy it! Recently noticed oil under my car. Took engine under cover off,& it was full of leaked oil! Had lost most the oil. So emptied the rest. Replaced oil filter,& filled with new oil,& this AMAZING PRODUCT! It's worked Very Quickly!! I think this was probably due to carrying out oil & filter change? Rather than just adding this to old oil. HIGHLY RECOMMENDED! 07 June 2016
    Rated 5 out of 5 by I'm so impressed Previously in my 2002 Ford Focus Zetec after 40 miles trip on motorway engine oil level from maxim goes almost to empty, today after using Wynn's Engine Stop leak I have checked oil level after the same trip it was still full. I am really suprised, but at the moment after 50 miles affects are really amazing. 27 February 2016
    Rated 5 out of 5 by Great stuff My 15 year old e46 which has done 160k has an internal leak in the engine where it is leaking diesel internally. After sitting overnight the smoke coming out the exhaust was terrible,so bad I couldn't start the car if someone was nearby as they d get smoked out. Put a tin of this in and it pretty much stopped the smoke for a year. Says on the tin 100 miles until its effective but my issue took longer, more like 400 miles.Away to buy another tin and hopefully will sort it out again. Really didn't think this stuff would work but was pleasantly surpassed. 22 February 2016
    Rated 2 out of 5 by Better but not fully cured! Put this in with oil 200 miles ago. Has seriously reduced oily whiff coming into car. Might try another can to see if it completely seals minor leaks. 10 January 2016
    Rated 1 out of 5 by Do Not Use used this in our Diesel Touareg due to very minor oil leak after few days of using this product our camshaft was completely gone along with buckets and the engine was clogged up and all this was due to stop leak. My advise is please stay away from this product or you will end up spending thousands on repairs as this product is poison for your engine! 06 January 2016
    Rated 5 out of 5 by Good for a temporary fix if your car is needed Good for a temporary fix if your car is needed for driving before getting a full on fix. I own a range rover and have timing cover leaking/ valve cover leaking. garage has 2 weeks waiting list before they can fix the issues. Thought would give this a go and its seems to have slowed the leak down, this stuff is meant to expand rubber orings and seals. so in my case the leaking timing cover must have expanded and helping to prevent the leak which is good. Note anything like this should only be used as a temp fix and not used long term but for the short term its works! 27 November 2015
