Keith Bobo says Lucas Oil Products Perform Miracles

I don't usually do things like this but after using your power steering stop leak in my van with GREAT success and now your transmission treatment in my New/OLD 1996 Suburban with 153.000 miles, which is older
than my van that has about the same miles on it. I have many good words that come to mine, but I will just say one UNBELIEVEABLE. I have used your spray wax and fuel treatment as well, very very good. All your products should have the word MIRACLE listed in the description somewhere, because that's what they do, perform MIRACLE.

So with all that said I would like to say THANK YOU VERY VERY MUCH!!!
