I just calculated what I would save if I could manage 30mpg instead of 22mpg as was the case with my last tank of gas and here is what I came up with. At 30mpg I can get 480 miles on a tank of gas so I will use that as my millage number for both mpg (my tank is 16g). I also figure that I use 2 tanks of gas per month.

@ 22mpg
480/22 = 21.8g
21.8 x ~$3/g = $65.45
($65.45 x 2) x 12 = $1570.90

@ 30mpg
480/30 = 16
16 x ~$3/g = $48
($48 x 2) x 12 = $1152

So if I can improve my average fuel consumption by just 8 mpg I can save $418.90 per year...not bad for just slowing down and improving my driving efficiency. I'm hoping by the end of the year, however, to increase my millage to almost 40mpg which would save even more.
