I wouldnt get too hung up on the trip computer and gas consumption ...u should reset the fuel consumption as well.. just hold the BC stick button and it will go to will keep going up and down (depending on driving conditions) until it settles at a final number..there is nothing wrong w ur car

i calculate MPG the old fashion way..fill up and reset trip and when u refill again just the divide the trip mileage by the # of gallons u filled with

My comp says i am making 12.7mpg when in reality i make closer to 16..i drive like a maniac and am tuned w FBO, so it sounds about right
