Re: First Tank and newbie question We just took home our brand new Red Prius not 20 hours ago. On our way home we found that the screen said only about 32 mpg estimated. Of course we were concerned and came here and realize that it takes some practice to get into the techniques of gas saving driving. Also we only drove locally not 10 miles each trip so I would imagine that has a lot to do with 'poor' mileage. Okay really dumb newbie question -what does MFD stand for? thanks
