Carl Hopkins uses Lucas Fuel Treatment for '93 Pete


My name is Carl Hopkins. I've been driving since 1976. I just got my own truck, a used '93 Pete. I was having problems with fuel filters and oil leaking. Friends told me about Lucas Oil Products but I still did not believe in it. Until I was in the desert and my fuel filter problem was getting 3 miles to the gallon of fuel. I changed one filter but could not get the other one. I bought fuel and another driver said to put Lucas Fuel Treatment in the tank, so I did! It cleaned it up and I was now at 7.25 miles per gallon. What good STUFF! If your treatment can do this to the fuel, I thought what can your product do for my engine. So I changed the oil and put Lucas Oil Stabilizer in it and I could tell the difference right away. Thank you for Lucas Oil.
