    It's a dated thread but I still do not accept increased gas mileage as necessary with increased performance. That was OK in the 60s and maybe even in the 90s, but in the 21st century there is no reason we cannot have higher efficiency as well as higher output. Seeing the WRX's fuel consumption actually increase would be terrible, and reason enough to avoid the make.

    Hmm....not really true IMHO.

    I've knocked on the 30mpg mark with both my 06 wrx and currently with my STI.

    It's all in how you drive/maintain the car.

    I drove exactly 403 miles (all highway) on a single tank of gas a few months ago. Richmond, VA to Greenville, SC nonstop. Yes my warning light was on

    30.2 MPG on plugs with 60k miles. just changed the plugs today - and driving 954 miles on thursday! I'll let you guys know my mileage average.

    Unhappy Gas Mileage Tips

    Okay so I read all the responses but what are really some good ways to increase the MPGs. I am a new WRX owner (2002) with 102k on it. Only getting 13-14 but live in chicagoland and do way too much short distance driving. Also the car is a automatic. I am ready to do some maintenance to it but would appreciate some tips on what could be done to increase the MPGs. Hoping to get 18 MPG. I personally baby the car and don't drive too hard but I do have a 16 year old that may do that.

    Any suggestions would be appreciated. Thanks for the info.

    Not really sure how similar what I have been learning will be with an older model (I have one of the 08's), or if there will be any changes as I add miles- just hit 1000 last week.

    But-

    light throttle pressure seems to be MORE important than the rpm I drive at.

    My mileage seems the same or slightly better when I upshift around 4k/4500 than when I try to stay out of boost entirely (shifting below 3500.)

    Cruising around town at 4000 gets me better results than 3000.

    My guess as to why is that when I am in the power more, I need less throttle to accelerate.

    Again, as the engine breaks in more thoroughly, this may change somewhat, but if anything I expect it to improve just a bit.

    Ways to get the best mileage possible:
    1. Change your air filter.
    2. Change your plugs.
    3. Drive with a soft foot. NOTE: You will get the same gas mileage at 40 MPH at 3k RPM in 4th gear or 2k RPM in 5th gear as long as you are light on the gas, so upshifting is not the easy answer. Anybody that says different isn't OCD about numbers like me and hasn't done a lot of totally unnecessary tests like I have.
    4. Use cruise control on the highway. 1-2 MPG increase or more depending on how you drive.
    5. Remove extra weight from the car. Every 100 lbs you remove will give you about 1 mpg extra.

    That's assuming the highway is relatively flat. Up steeper inclines cruise control will use more unnecessary boost than if speed was maintained manually. At least that's been my experience. Other than that, good points.

    I have an 02 with about 68k miles. Its running stage 2 but I only get about 17MPG and thats even when I drive it lightly. When I say lightly I mean shifting at 3k EVERY SINGLE TIME! Does anybody know what i can do to improve it a little bit? This $3.70/gallon is killing me as a student. Thanks

    Develop a slipping clutch. My car hasn't seen boost or higher than 3k rpm in weeks.

    so if im at 40mph in 3rd gear and my rpms are like 4k its the same as 3k rpms in 4th gear? or is it only like that in 4th and 5th? how did u find this out anyway hahaha
