Terrible gas mileage. Need help!!

I have an 2002 wrx sedan and just drive in town about 1000 miles per month i get anywhere from 215 to 230 per tank all city miles. I have taken it to south carolina and got a whopping 340 miles per tank. I guess high gear ratio at higher speeds is what that is. I rarely hit fifth gear in my car around town so the lower gear ratio might be all the difference.
Even though you might not be passing 4500, how are you steppin' on the throttle? Easy offs, and not pedal to the metal! Saves a lot of gas. When I got my car from factory, I had 320ish, but now it's more or less around 250, depending on how grandma-ish I want to drive to save gas. You do have an '04, I believe they are 19city, 26HW?
Alwell, Just be happy you make it close to 250. Remember their highway miles are calculated at 65mph I believe.

I have an 04 sedan 5spd with 2k miles. My gas milage varies big time. I have never let my gas light come on yet so I don't know how many miles I REALLY get to a tank. The worst I've had so far was the very first tank of gas which was at 1/4 of a tank with only 165 miles on the tank. That only happened one more time and that was during a weekend of snow where I had the defroster on the whole time (meaning ac was on) and was idling a lot because of traffic and letting the car warm up.
The best i've seen so far was this past weekend when I got 170 miles with a little less then 3/4 of a tank. (all highway) I will let the car go down to the fuel light next time I fill up.

the most i got is about 280, i havent even reached 290, i think 300+ is impossible, i mean up until the redlight.
if i drive agressive i get about 130-160
weekdays i drive to school i try not to exceed 3000rpm

It's pretty irrelevent how many miles you get "on a tank" or until "the tank is half full". Een a small difference in how your gauge reads will have a huge difference.
Do this. Fill up the car and zero the trip odometer. Drive until you get to a quarter or so. Fill it up again. Divide the number of miles on the trip odometer b the number of gallons it took to fill it up.
What you get is miles per gallon (MPG).
Then see if your MPG is out of line.
My wife and I both have WRX's (Mine is modded, hers not) and there's about two gallons difference in the amount it takes to fill our cars when they indicate half full.

OldGuy mentions checking when down to 1/4 tank. That's what I do, also. It's also important to allow at least a certain minimum amount of gas to be burned before checking because if you only drive a couple miles then fill 'er up again, the results will not be as accurate as when calculated over many, many miles.

I drive like my foot's made of lead and last time I measured I was getting around 16. Sounds like you are getting around 13
I'd check tire pressure. Also try to use the best quality gas you can.

could be better
Well your milage should be better if your trying to get good gas milage. You can get nearly 30 mpg on the highway. I have averaged about 24 mpg for the last 30 thousand miles.
Check:
tire pressure
use 5th gear on the highway
bad O2 sensor ( have you ever run leaded fuel)
bad pre-cat -- melted due to over rich mixture, creates huge back pressure in exhaust manifold.
Boost leak could also make you use more fuel, check hose clamps etc on turbo to intake manifold section of intake.
Make sure your running the proper octane fuel. If your on the cheap and running regular or mid grade fuel the ECU will run a super rich mixture to protect the engine, and you will get crappy gas milage.
Check for the fuel leak in engine compartment some folks have reported in cold weather. (does you car reek of gasoline when its cold)
You will loose a little bit of gas milage in the winter time if you live in a metro area that switches to oxygenated fuels during the winter.

My old Mustang 5.0 got better gas mileage then my scoobie. Are there any Techs on this site that can give me any more info?

Unless you have a code reader, you should definitely take that car back to the dealer and have them check it out.
As for things to check, do you smell fuel in or around your car mainly in the engine compartment area?
Check and make sure the the intake air flow is not partially blocked.

I usually get 220-240 before the yellow light goes on in the city. On the freeway 300-320...
But this last tank is by far the worst. I don't think I'll break 200 before the light goes on. It's the lead foot
. Just put in TXS stealthback a couple weeks ago and I'm loving the pressing-me-back-into-my-seat acceleration much better than the old stock feeling. That'll end soon as gas is not cheap.

my mileage has gone down the drain as of late. the light is about to turn on and im only at 230ish miles, but thats all city driving. im going to reset the ecu tomorrow night and have it relearn my driving habits while i drive on the highway.
