How much you paying for gas now ?
Heading out to run some errands in a couple minutes. I'll check and report back....(to be continued)....
Edit: at the local Walmart, tri-state az, $3.09 for 87, $4.39 for diesel. I can drive 20 miles round trip and beat that by a bit (ONLY if I have something else that has to be done nearby) and the local name brand stations are 50-60 higher for each.
