  1. Thank You! 5 Star Review

    Posted by on 21st Jan 2014

    4.5.11, I have a 2001 BMW X5 which developed a serious oil leak (everytime I stopped, there was a spot). I put a bottle of BlueDevil Oil Stop Leak BlueDevil in the oil and after a couple of days of driving, the oil leak was gone except for a small drop here or there. I put in another bottle and after driving for a 3 hrs, not a drop no where. The truck seems to be driving much better also, had white smoke out the back, now no more smoke. I am so pleased with this product, it really works. I'm telling everyone I can about it!! Thank You for producing this product... " TC Campbell - Winnetka, CA

  2. Zero Leaks! 5 Star Review

    Posted by on 21st Jan 2014

    I used BlueDevil in my van which has 130,000 miles on it - and I saved $1,000 - that was the quote for replacing all the seals. I am stunned at how effective it is! Zero leaks! Your product is great! Gary - Woodruff, SC

  3. Tractor Fix! 5 Star Review

    My 1949 tractor was leaking oil considerably. After using BlueDevil, my leak stopped completely and my tractor is running better than it ever has!

  4. Back on the Road 5 Star Review

    Posted by on 21st Jan 2014

    BlueDevil has put my Acura Legend back on the road for less cost than a tank of gas! After using synthetic oil for ten years, so many of the gaskets and seals had started leaking that the repair estimates approached $1,000.00. I put BlueDevil and fresh oil in last Sunday and drove it for 3 hours, then all week, and have not seen, or smelled, any oil leaking at all! I am very impressed, and grateful. Thank you for a great product. "

  5. Thanks... 5 Star Review

    Posted by on 21st Jan 2014

    I just wanted to offer my thanks to your team once again for the unrivaled products you offer in the automotive "stop leak" realm. After finding success in using the trans sealer in my truck a couple years ago, I thought only of BlueDevil a week ago, when my engine exhibited a small oil leak underneath the pan. I take great pride in maintaining my (2) vehicles for looks and performance - and both have over 130k miles on them, (being 12 and 14 yrs. old). My truck is set up for performance and employs some modifications including a supercharger. I do not tolerate burning or leaking fluids, and keep a close eye on my garage floor for early detection. When the first drops appeared a couple weeks ago I was disappointed, but knew what my first reaction was going to be. Driving only (1) day, (about 50 miles) after adding your engine "oil stop leak" product, the leak was completely sealed. I was unable to determine which seal was leaking in my previous inspection due to the limited view available from most vantage points. But the beauty is, It doesn't seem to matter! I carefully cleaned the areas where the oil had run down and my engine and concrete have both remained clean ever since. I would like to also thank your tech staff who answered a question I submitted online by calling me on my cell phone. It is such an incredible product that let's you avoid literally hundreds of dollars and/or worse: extended down time - all by just pouring in a $20 bottle of BlueDevil. I don't take that for granted. Thank you! Mark - Lusby, MD
