J. Trigg uses Lucas Fuel Treatment

I own a 2002 Nissan Frontier "Desert Runner", 5 speed, 6 cyl., 2WD, currently at 97K miles

EPA estimates on vehicle: City = 15 MPG, Highway = 17 MPG

I track my gas mileage on the computer every fill-up and burn 87 octane gasoline from Texaco, Valero, or Shell.

Started using 3-4 oz. of Lucas Fuel Treatment every fill-up in January 2008 with ~86K mile on the odometer, and at that time was averaging 17.2 mpg. As of July of 2008, I am averaging 20.3 MPG on the same vehicle, same driving habits and trip, and with ~97K miles on the truck.

This, for me, is a "trip and a half" to my work (about 45 miles) for free each tank full, based upon gas usage prior to the Lucas.

16 gallons x 17.2 = 275

16 gallons x 20.3 = 324

A quart of Lucas costs me about $10 at Walmart, (now using it every other fillup) so it is well worth the cost of the treatment in savings.

Pretty impressive that the treatment works so well, increasing fuel efficiency on a truck with almost 100,000 miles, and the only other things I do with the truck is regular oil and filter changes.

The increases were gradual over time, but consistent and visible when tracked. I continue to use and recommend this product.
