As advertised
I used this 2 times now the leak never came back. The first time I used it I was really sceptical about this product still leaking for two days but as I drive along the leak suddenly disappeared. So when I did my oil change I pour another bottle no more leak up to now. I think it does its job kudos to the seller and kudos to bluedevil.

THIS STUFF WORKS!!
I have a 2009 F150 with over 337,500 miles on the original engine. It developed a persistent rear main seal leak about a year ago. Having called the local dealer, I was quoted labor only of $1,900 to repair this leak. I went on Amazon to see if there might be anything out there that would help. I purchased this Blue Devil pour and go rear main sealer and had it delivered next day, put it in the crankcase as instructed and drove to Ft. Lauderdale (200+ miles roundtrip) So far, after about 400 miles, it looks to me that the leak has stopped. I'm hopeful that it stays stopped and will no longer be a mess on my paver driveway!! I recommend this product based on this outcome.
