Mack Carnahan uses Lucas Fuel Treatment in 1986 model S10 Chevrolet

I recently purchased a 1986 model S10 Chevrolet. The engine was very sluggish so I had talked to a friend and he asked if I had ever tried Lucas gas treatment. He said he had used it in his wife's Maxima car. It made the check engine light go off. So, I got a bottle and put it in the S10 and it runs great. I recommend this product for anyone. Thanks very much for a great product.
