hey, there must be something wrong with your car since it is getting that bad of gas milage. My 99svt gets 18-23mgs driving around town, 5 minute runs. On the highway I get around 33mpg, and that is with a clogged up stock paper filter with 37k miles on it. If you just bought the car, I would definately take it back to whoever you bought it from. SOmething is not right. Could be the computer. Are you sure you are calculating your mpg correctly?
