Not getting Estimated MPG

My 2015 Mazda3 automatic is returning an 8000-mile lifetime average of 42mpg, spent mostly on the highway. That's one mpg better than the EPA highway estimate and is better than most Fuelly reports for the same car. I think those other owners are passing me in the wolf packs.

Cool. Of course, you pass the wolf packs when they are gassing up....AND you don't need to! Go to pure-gas.org to find 100% ethanol-free gasoline(E0). E0 should raise your mpg by 8% to 5% as compared to 10% ethanol blends(E10). Ethanol can only extract its energy efficiently when used in high compression ratio(16:1) ethanol engines. Used(NOT burned efficiently) in low 87 octane, low compression ratio(9:1 to 11:1) gasoline engines, ethanol fails.
