I didn't track mine that close but I know some of the others did on our 5000km trip to Georgia. At the gas station my M6 SS was usually within 50 cents to a dollar of the others. Many were getting 26mpg's on the highway but nobody cracked 30mpg's that I know of. The best gas mileage of the group seemed to be the automatic v8 but not by that much.
