Im sorry if this has been brought up before but i looked everywhere and could not find it. I drive a 135 and occasionally push the car but try to drive moderately in traffic, around the city etc. A little more info: It was purchased used with near 45000 miles on it (no flash/tune present and just had a firmware update as well). Anyways, according to my car I'm getting 15.4 mpg, which is horrible. I've had to fill up my tank 3-4 times in the last week and a half. Im not sure if its due to the way i'm driving or if there is something wrong -- no CEL or SES present either
