Donald G. chas improved his 2004 F-250 V10's Fuel Mileage with Lucas Fuel Treatment
Just wanted to let you know that for the last 6 months on the recommendation of my mechanic, I have been using the gasoline/diesel fuel additive to my 2004 F250 v-10. I get an honest 1 mile per gallon gain in fuel mileage plus the truck runs better than ever. I just returned from a 3,500 trip with a 2,000# truck camper in the bed on got a 11.58 miles per gallon average for the entire trip. I was hoping for 10mpg. I will continue to use your product and I recommend it whenever I can!
