Picked it up Saturday night at 7pm, filled it Sunday afternoon about 3pm. It had 15 miles when I got in it and read 265.4 when I filled it. It took $20.01 of premimum at WalMart and that was 6.761 for a calculated 39.254 mpg. But who know if it was filled up or clicked off when I got it and I filled it until it ran out. No interstate driving, but lots of starts, lots of hills, probably 25% city in 50 degree weather. So far so good.
