Unfortunately, I have a FlexFuel 5.7 2013 CM and I'm getting 8.2-8.7 mpg around town also. I'd say that I drive conservatively also. A fair number of stop signs and an average running speed of 40. I only have a 1000 miles, and hoped that it would resolve itself once the engine "breaks in." Hmm, I am going to have to research this issue. D#mned Flexfuel.

I have the same truck you have and have been averaging close to 15 around town and 16-18 on the highway. Something isn't right there shouldn't be any reason why we all shouldn't at least 1-2 mpgs within each other.
