Eric Lunneborg uses Lucas Fuel Treatment in 1993 FORD F-150, 2001 CHEVY ASTRO

I work at a TA Truck stop in troutdale Oregon. One night a driver for CRST came in and purchased a gallon of your fuel treatment for his tractor. He told me that it was the best fuel additive out there for the buck$. In Oregon, we have no regulations on fuel, so there for, our fuel quality is pretty low. The driver told me that he got a 20% increase in milage. So after I got off of work, I purchased a bottle and filled up My 1993 Ford F-150 with 87 octane gasoline and Lucas fuel treatment. Here is a little more info about my truck. It has a 351 windsor engine with 98k miles on it. It is a 4X4 with a 4spd tranny. I was getting a misserable 15.5 mpg on the freeway! ugly ugly ugly!!!!!!!! The next day I had to go out and pick up parts for the shop from another location. I drove for 120 miles. I came back and filled up my tank. (6.64 gallons of 87) do the math! 18.07 MPG! WOW!!! My average MPG (city/hwy) is 14.5 MPG! My truck gets 18 miles per gallon on the freeway! My dad drives a 2001 Chevy astro. He was getting 17 mpg on the freeway. He now gets 19 MPG on the freeway. I will continue using your product until the day I die. Keep it up Lucas!
