Kevin Fox uses Lucas Fuel Treatment for 1994 Chevy S-10

I have a 1994 Chevy S-10 with a 4.3L V6. It was running a little rough and the dieseled badly when the engine was shut off. I ran a bottle of your gas treatment thru 3/4 of a tank of gas. As soon as I left the gas station and was driving off the truck got a sudden burst of energy. By the time I had made it down the roadabout 4 miles the truck was running as smooth as a sewing machine and the engine shuts off as it should.

I was so impressed that I purchased several bottles and gave one to my younger brother who is a police officer. He ran the bottle in his patrol car. He stated that he knows his cruiser reaches over 100 mph. Because the car is running so rough it feels as if his engine is coming apart. After adding the Lucas fuel treatment he was in a pursuit in less than three hours. He said he looked at the speedometer abd was passing 120 mph and it was still running smooth.

Since these experiences I have switched to Lucas to several applications such as the gas treatment, Oil Stabilizer, Red and Tacky grease and your gun oil.

Thanks for such a great p
