  1. 265,000 miles and Rear Main Seal fixed leak!

    Posted by Lou Medina on 24th Jun 2014

    '92 Camry with 265,000 miles leaking 1 quart of oil every 4 to 5 weeks. Tried various stop leak products with no success. As a last resort I tried Blue Devil and it slowed the leak in the first week and after several weeks there were no more oil leaks. I still find it hard to believe. I even saved the sales receipt because I was sure I was going to have to ask for my money back! It was highly recommended and with the money back guarantee what did I have to lose.

  2. surprised me

    Wasn't sure about the stuff but read some reviews and thought I would give it a shot and the stuff works. But it in my 92 dodge that would leave big spots where you parked it. It also sealed the valve cover that leaked and always smelled burning oil. Have new valve cover gaskets to put on yet. Surprised me that it sealed everything including the valve cover that it thought was shot. This is great stuff. Going to but it in my other vehicles.
