odd.. my manual, and in the door-jam, it calls for 33 psi.

You also might want to cover for the greater audience the operating conditions in CO (altitudes) . Frankly, I am not sure if they still do high altitude blends of RUG to PUG. I have filled a PUG and D2 vehicle of late (in CO) but did not pay any attention to the blending issue.

No, it is not odd at all. My D/S door jam says 30 psi. However in the context of better mpg, PSI is a variable. Generally in the "correct" range, higher psi tends to yield better mpg.
 
Of course one can pick and chose what variables to pay attention to or ignore for a host of reasons. One can employ ZERO to all techniques. This thread is a good place for discussion.

I don't know any specifics about it, but if it's any response to what you're asking, all of the stations around here are required to have a fuel blend with a higher level of ethanol. I believe the standard blend is 10% ethanol, whereas here in CO it's mandated to be at least 15% -- some stations are as high as 18-20%. I think it's the same between regular, mid, and premium grades of fuel.
 
I'm not sure what that does for the fuel, engine, environment, etc. though... Is that what you were referencing about high-altitude fuel blends?

What makes your stated mpg more significant; is over all altitude, (normally aspirated engines: to which Civic's ARE) performance (mpg among others) is zapped and pollution is greater. ( other than sea level) (to which this things are measured)

MPG over 10,000 miles by chillipepper1

I have an 07 LX sedan/auto trans with just over 10,000 miles on it. For the first 3000 miles with air conditioning on, I averaged between 31 and 35 MPG (34avg).
I then increased the tire pressure to 35 psi and the weather permitted me to run without AC and have averaged 37 MPG for the last 7000 miles. Some of this gain is the tire pressure, but a lot is due to not running the AC. My driving is 80% highway commute. I live in Dallas, so the highway miles include a lot of stop and go. I generally drive between 40MPH and 60 MPH and never go over 65 MPH. I think all of you that get less than 30 mpg either are driving a lot of city miles or drive with a heavy foot.

So my second tank, I'm up to 33 MPG. That was a definite surprise because I did not push the transmission into 5th gear as often and I also let the engine rev a little more as I was getting past the initial break-in period of keeping revs low. Pretty happy as my fillup was still under $27 for close to two weeks of driving!

2008 EX-L Auto MPG by dwjones

I have a 2008 Honda Civic EX-L automatic. So far, a bit over 2,000 miles. Here's what I have experienced for gas milage;
 
Worst tank: 19.6 MPG
Best tank: 44.3 MPG
Average: 34.7 MPG
 
Generally, I've been averaging 28-29 MPG in city driving, which is suburban driving for me. On the highway, I can get 42-43 MPG if I set the cruise control at 65 MPH. At 75 MPH I get 37-38 MPG.
