  2. Second treatment did the trick 5 Star Review

    Posted by on 14th Nov 2016

    Review update. Got the second bottle to retreat my car free of charge. Didn't even have to pay shipping. My car no longer leaks any oil. Sometimes it takes a second shot. I geuss but I can say it. Works. Save me well over a grand and alot of headaches. Thanks again blue devil!

  3. Magic in a bottle 5 Star Review

    Posted by on 3rd Nov 2016

    I had a couple leaks on my 94 BMW 525i. Car has 265k it would leave 5 or 6 big drops overnight. After 1 bottle and a few weeks it is now 1 small drop or 2 over night. That alone to me is worth it. Haven't had to top up oil since using the bottle. I contacted blue devil who is very easy to get a hold of and they promptly shipped me another bottle free of charge recently which I haven't had time to receive. I'm sure another treatment will do the job as others have also said. My car takes 7 quarts of oil and it treats 4 to 6 quarts so that may have been a factor. The customer service alone is enough for me to be satisfied. Thx again!

  4. I thought it would work 3 Star Review

    I knew i had a bad leak but all the advertising around this product encouraged me to give it a try. Slowed it down but not near completely.

    Maybe i should try more?
