Terrible gas mileage. Need help!!
I have a 2004 WRX sedan 5spd and I am getting horrible gas mileage. I have read people talking about them getting about 240-280 miles to the tank. I have only been getting 200 miles at the most! Something has to be wrong with my car. It only has 1300 miles on it. I usually keep the rpms below about 4500 as well. So I don't beat on it that often. I need help ASAP. I don't enjoy filling my tank like 2 times a week. Gas is mad expensive now. Someone help me out.

You've got to find that happy middle ground between lugging the engine and getting into high boost. Steady-state cruise conditions is where you will find the best fuel economy. Even in heavy rush hour traffic I still average close to 23 mpg. I do drive with a light foot and try to be smooth on the go pedal. Avoid even little on, off, on, off, applications of the throttle whenever practical. I ease away from stoplights and reserve 5000 RPM launches for the drag strip.
I also try to consolidate my trips so that I do multiple errands along the way, rather than going home after work then going out again to get gas or go shopping.

Do you really think there is something wrong with my car? I mean, I knew this car was going to be worse on gas then my civic. But 200 miles to the tank!!!! Come on now. That is definitely crappy. 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?

There is definitely something wrong with your car, or with your driving habits. I get 270 miles/tank in the summer (AC on every single minute I'm in the car) and 300 to 315 miles per tank in the Winter (AC not on at all) on Techron 91. I don't dig into the boost all that often (mostly accelerating onto freeway) but I do hit speeds well over 80 on most highway trips, and I do a fair amount of stop-and-go (damn Phoenix traffic!) in city streets (about 4 hours of that a week).
If you are running the AC full blast and boosting away from every stoplight (throttle 3/4 or more down, RPMs topping 3200) you might be getting down to 220 per tank, but 200 seems suspicious. Are you judging by just one tank? Try this: for your next three tanks, don't refill until the yellow light comes on (don't worry - you still have 1.5 gallons left at this point!) and then write down your exact miles and reset your trip meter. If you average 200 over three tanks, you've got some kind of problem (or your right foot is made of STELLAR MATTER).

what's the BEST tank u ever had with your car?
i'm wondering, cuz when i first got the car, even while running no boost during breakin period, like the first couple tanks i'd only get around 200-220....then it started getting better from there.....then now i dropped back down to about 250- 270 a tank due to boost crazed.

Check your tires overnight cold with a good digital tire gage. Drive with medium throttle and shift at 2500-3000 rpm and recheck your millage as per another on this post ie 3 full tank check. Let us know how you do. If your millage does not improve then reset your ECM by disconnecting the main battery for ~ one hour to reset and recheck millage. If no improvement a trip to the dealer would be prudent to have your car checked. eddie
