Justin Wisdom uses Heavy Duty Oil Stabilizer in his 1979 K5 Blazer

First let me say that seeing is believing. I own a 1979 K5 Blazer eith a sml blk 400 and live in Colorado.I did the average oil changes with 10w30 valvoline motor oil. I have seen Lucas Oil on tv and thought it was another gimmick, but as I started watching more racing and started seeing your logo being posted mor and more. I realized that it might be good, but not this good. My motor had lost power and was having a hard time starting even in the summer. I added the Lucas Heavy Duty Oil Stabilizer and WOW what a difference it made. It starts right up runs so smooth that I can balance a nickel on edge on the air cleaner. I am definately going to recommend it to all my friends and family. Thanks alot for your product. I am now going to use it in all my vehicles.
