  1. Please Read ! 5 Star Review

    Posted by on 17th Apr 2014

    I had water pouring out of the tail pipe like someone had turned on a water hose , After using Blue Devil I was amazed it really works , I thank the maker of this product , Anyone who says it dosen't work must have not followed the instruction . I had a shop look at my engine after I used the Blue Devil not telling them what I'd done received 100 0/0 no problems . Thank you Patricia Slater KCMO

  2. GREAT! 5 Star Review

    Posted by on 21st Jan 2014

    I used the Head Gasket Sealant about 3 weeks ago. Carefully followed all directions. I am very pleased that the car is running beautifully. The engine has GREAT power and no white smoke. The car has been driven approximately 200 miles. Question: How many miles must I put on my car before I drain the radiator, put in antifreeze and replace thermastat? Thank you so very much for saving my car!!

  4. Great Stuff 5 Star Review

    Posted by on 21st Jan 2014

    Just thought I'd drop a note of my experience with BlueDevil Head Gasket Sealer, the yellow label. I know it says that it's not recommended for the North Star motor but I had to give it a shot. I think the bottle states that because the North Star usually has head bolt issues and a sealant may be a tough fix. Anyway, I had a shop do the treatment (they weren't thrilled about it, but the they did it) and made sure that they followed the instructions explicitly. It worked! More than a 1,000 miles later it is still holding. That and consider I live in Phx, AZ so may average outside temp for the last 1,000 miles has been over 100 degrees and I'm pretty impressed!! I don't think I got lucky, I think conditions were just right. My leak was very slight, we followed the instructions and the circumstances were right. Thanks, great stuff. Gino - Phoenix, AZ

  5. Great Product! 5 Star Review

    What a product! The BlueDevil products are amazing. It helped stop my power steering from leaking on my 1998 Land Rover Discovery. BlueDevil is a great and easy to use product. It saves time and money, and it really works! No more costly repairs and time lost at dealerships or mechanics. Just follow the directions, it is just that easy! No more black spots on the driveway. I would recommend this to every do-it-yourselfer out there. - B Rosenberg
