Is it just me, or have others realized that by doing the math on your miles driven since last fill up, dividing by the gallons just filled, you get a different avg mpg from what the little dash guage shows? Recently I posted I was in fact "stoked" at the avg MPGs of my little beast, whereas after I actually did the math (as above), my "stoked status" dropped to "okay happy" status. Who's with me on this little fact? (*sorry for misspelled word in title: won't let me edit that.).
