David Lester uses Lucas Fuel Treatment in 2007 F-350 6.0 Diesel

Ok guys, I'm trying it, just to see if it does work. I noticed right away that the chatter of the diesel it's not as loud as it was before using it. I'll keep you up to date on the fuel mileage as the last tank with out the treatment was 12.39 MPG! I'll let you know soon. Thanks, David Lester 12-30-2006
