The 6-speeds (LX, EX-T, Si) can easily break 40mpg on the highway. Your picture really isn't remarkable. See this thread for the ridiculous numbers the CVT guys can get without effort.
Guys, the thing is, these kind of threads are useless. It depends on where you drive, how you drive, the gas you use, the temperature, etc. etc. etc...
Suffice it to say, the 10th gen Civic is capable of some great MPG numbers.
