wayne uses Lucas Fuel Treatment in 2001 Lincoln LS

I just purchased this car with 73000 miles. Becase of the cost of gas I needed to try something. When I first got the car, my average MPG was 16.9. after one tak of the Lucas fule treatment, I am noiw getting 18.6 MPG. I plan to start using it in the family's other vehicle, 2000 GMC Yukon with 130000 miles.
