John Stepler Will Never Fill Up His 1989 Corvette without Lucas Upper Cylinder Lubricant

I want to make a comment on how well theLucas Upper Cylinder Lubricant worked for me. I am thrilled at the difference I am feeling in my 1989 corvette. It was sluggish and idle was rough. Now that I have ran 3 - 32 oz. bottles through it has made a total change. I feel as though I overhauled the engine!

Thank you Lucas ! I'll never fill up again without!
