I just checked my 04 civic to see my mpg and it was 20! My tires are at the right pressure I dont drive like and ass, (if anything I granny shift) I have replaced the air filter and still get only about 20. Anyone have any suggestions, or possible explanation why my mpg is so low?

I don't know the answer, but I first got my car I got about 32, now I'm down to about 25 with 12,000 miles... But it's at 25 MPG if I drive hard and 26 if I'm nice. Don't get it?
I have a 2002 civic sedan and get 22mpg usually. Since I got that hyper voltage system installed, it's up to around 25. For an 04 though everything should still be new as far as air filters and stuff. Make sure the tire pressure is 32psi I think.
It also depends on your driving. A while back I drove all highway miles and got 30mpg, which is still bad. The most mileage you will get is with all highway driving.
I'm gonna assume your civic is stock, as in no upgrades or heavy things in the car like subs. Again the car is new, so that discounts the maintenance related items. Go pick up a bottle of techron fuel system cleaner and try that. Make sure fluids are all full. Other than that, you really need to take it to a dealer and have it checked.
But I know how you feel. I think I could have gotten 20mpg if I drove the car hard, instead of 22. If all else fails, just get a hyper voltage system. It's easy to install--connects to your battery and stabilizes voltage for every system. I'll know for sure if it works pretty soon.

What exactly does ht hyper voltage thing do? I know you siad it stablizes the voltage, but how so? I have some knowledge in electrical enineering, but don't claim to be an expert or anything.
Hyper voltage system has multiple capacitors in parallel I believe. It releases stored charge when voltage drops are detected in the system. Thus keeps everything flowing smoothly. I'm pretty sure it increased mpg by 2-3.

Ive checked all my fluids, and tire pressure is at 35psi but i have 17's. As for driving when i tested my car to see my average mpg i was granny shifting most of the time. As for high way driving i say it was prob about 1/4 of the tank the rest was city, but 20 is still low. Iam gonna try putting in techron fuel cleaner and see wut happens with that. If nothing then to the dealer it is.
ONe mentioned one more thing, you have 17's. That will drop it a couple MPG too. It move the moment of inertia outward thus creating more inertia, more inertia mean you need more power to start rolling and keep rolling. I get alot of skeptaism on this, but I have a drevation I did in physics class to prove it. And if you don't believe me, look around and people will say 17's suck for racing and hurt you off the line, the increased inertia is why. Put your stocks back on and see if they make a difference.
Like I said though, this should only be a few MPG, 3 maybe 4 at most. That only puts you at 24 and that still sucks.
It's really strange, but gas mpg depends on a bunch of different factors. Weight in the ride actually doesn't affect it that much. Maybe a couple mpg. Alot of it is also driving habits. Staying in VTEC or higher rpms will also cause lower mileage.

For what it's worth..... after a lot of trial and error I have found the following things:
My car gets the worst mileage on Chevron, any grade. So does my truck, btw.
It seems to get the best mileage so far on 76 Super. It runs better too.
I don't know why, or what the difference is, but I have been able to duplicate this every time. So maybe try a different gas, and different grade and see what the car does.
Gas is pretty much the same, but every brand puts different ADDITIVES in it. I think this affects the car more than the actual "GAS".
