I have an '04 5 door, and recently the gas mileage has basically been cut in half

i'm lucky to get 10 -12 mpg

:(


any ideas as to what might be causing this?

Cold weather? Prolonged engine idling? "Winter blend" fuel? (we get winter blend year-round in CA [10% ethanol], and I am averaging around 27MPG city/hwy combined since I bought the car)

This may sound weird but it could be your thermostat
causing your car to think its running tooo cold
thus throwing more gas in to make it run hotter?
this was happening to me then i got a new thermostat
:]
