My wife gives me sh*t every time I have to fill up. She drives a CTS and wonders why I have to fill up more often than her? Anyway I was trying to get the best possible MPG and so far I can only get 16MPG? It's city driving mostly, some highway. WTF Is it me or the car. I have got better than this but latley no way. A couple of tanks ago I checked the computer and I got an average of 11MPG!!:willy: I think I have a heavy foot, but dam, for the past couple of day I have been driving like a 90 year old and still I can only get 16!!! What say you?
