Bought a new Insight last June. It is a standard shift. In the summer following the purchase, I averaged about 70 MPG. Fall and Winter came and my milage fell dramatically. Low 60s. Still not bad but a little disappointed that I could not maintain my summer numbers. I couldn't figure out if it was just me and my driving habits or somthing about cold weather. My lifetime average dropped to about 65 MPG by start of Spring. Now warm weathers back. I got 750 miles between my last two fill ups. I zeroed the short term FCD at the fill up and averaged 76.6 MPG at the last fill up. I zero the short term FCD at ever fill up. So I conclude that the winter slump wasn't caused by my driving habits but rather something else. My lifetime MPG meter hardly moves any more. After about a year now it is 66.0 MPG and rarely budges. I keep a pen and a small notebook in the glove compartment and at every fill up I record the date, milage, gallons put into the tank and amount paid. Once in a while I compute a lifetime average MPG from this data and it corresponds to my the lifetime MPG on my FCD to within a fraction of an MPG.

So I'm really impressed with my Insight. A co-worker has a Prius. He averages low 40's. Got to wonder why anyone buys those. I can beat that with a Voltswagon Diesel.

Well, just my 2 cents for the record.
