Chris uses Lucas Fuel Treatment in 2003 Chevy S-10 Xtreme

I purchased the big bottle from a distributor when I went to put in my spray-on bedlining & he said nothing but good things about this stuff. He said to try it with regular 87 octane; I decided to give it a go. Before I used the fuel treatment, I was getting about 230 miles each full tank; now I'm getting over 250 miles each full tank. I've filled up my tank several times already & I'm not even halfway through my supply yet. A real money saver.
