Hello, All: Check this web site for your state, and see if there is a station close enough to justify your patronage. I'm fortunate, in that there are (3) within just a few miles from the house; one of which is on a path that I can follow to Ray's to do diligence on the RACE CAR. This happens to show Utah; there is a bar that covers most all states that allow cars to run well. After 3-4 tanks, my mileage increased by approx 20%. Jim http://pure-gas.org/index.jsp?stateprov=UT
