They must be driving it hard all day every day. Normal daily driving should be around 20mpg. You can do a search, and find out what more people say. I know real owners has posted their mileage on this board many times.

 

That seems a little low. Usually, I get on average 19-21. That is with some "spirited" driving.

 

There have been several lengthy threads on this issues already. Forum search is your friend.

People usually get around 270-300mi per tank (~13 gallon) with WRXs. The average varies a lot from tank to tank depending on how many highway miles you do. Also some people don't think much of gas price and take the engine to 6k at every shift, while some take the grandma approach in driving.

 

Tank is actually 15.9 gallons......

 

right. But tell me this, when you go fill up at a gas station, do u ever put in 15.9 or even 15.8 gallons of gas? Most people say xxx miles per tank, meaning when they get near the "e" on the gauge or in some cases, i drove with the light on for an extra day and even then i only filled up 14.7 gallons. Kinda got scary there heh

 

Becareful running it that low. Its not good to run boosted cars lean.
