Have an 09 CCSB 5.3 Flex 4x4 w/3.42 gears. Took a 600 mile trip to Chicago and back running 75-80 and averaged 18.9 for the trip on summer gas - no ethanol. I also had the tires aired up within 2-3 Lbs of max preassure for that trip as well.

Day to Day running e10 get ~15 in the winter and 16.5-17 in the summer. Thats probably 60% highway. Yet to try E85 see how bad it is. This is my wifes daily driver.

Day to day driving has been really consistant over the past 40k. Overall I'm pretty impressed for something that can tow 10k by the book. Now would I put more then 7k behind there- nope and that only occasionally.
