I get the exact same MPG. I don't even pay attention to the trip computer anymore since it seems to have a mind of it's own. I'm no expert but I expect my MPG to change every few days or so since I drive various speeds/distances. Not so; my average MPg stays the same for months. And I have a new gas filter, plugs and cap 'n' rotor. My next fix is the O2 sensor. BTW, my average MPH stays at 15; that hasn't changed recently either. Only when I drive for over an hour does it change; then next time back to a sub-20 number. I don't get it. Anyone care to explain????? TIA
