for those of you who hate reading about MPG posts, don't read this................. after finally snapping at 20-21 MPG on freeway driving ONLY, i had enough. something must be up with my car. i couldn't do anymore to get it to do better. 70-75 mph with steady throttle useage, short shifting (M6)very little hills where i live, and 93 octane top brand gas. nothing has made any difference. i took it in and they told me that they probabaly wouldnt find anything wrong as no codes have been thrown and that some engines just are not as efficient as others. bull****!!!!!! please. 5 mpg less than what they say is the average highway mpg is rediculous. something is wrong. if they can't find anything, i will be getting pontian rep down there. this is stupid and can't be right.
