Year/Model- 2002/ WRX Wagon Auto
chevron supreme is always used.(* im in oregon)
Milage= 31700
i have not got more than 20mpg since the last time i drove a couple hundred miles straight.
when im on gravel I get maybe 12mpg, street maybe 18. im pretty sure somethings wrong with my motor( my check engine light is on but when checked NO codes come UP, if anyone knows what this is caused by please TELL ME, Max419@hotmail.com its killing me. it only comes on when i drive at a constant rpm for a few miles, and only when driven like that. ive never had it come on in town only highway.)

sorry for the excursion. but ive only seen horrible gas mileage from MY FAVORITE CAR EVER.
LIVETODRIVETOLIVETODRIVETOLIVETODRIVETOLIVETODRIVE TOLIVETODRIVE and so on.

and please if anyone has any idea whats wrong with my car tell me.
I also recently have parked it due to a tranny problem when ever i hit the gas it stutters and will never grab. this happened very suddenly from parked to a quick drive, with no problems to parked for a few hours, and immediately, extremely bad, not driveable.
i dont know what this is, very tortured from it since me driving my car is my life.

Thank you
James
