Do you find the trip computer as being accurate? My truck, 09 CC LE 4WD AT, has 5,000 miles on it. I have never checked the mileage. Currently the reading is 17.6. It has dropped 1/2 mpg over the last couple months (strangely after adding a tonneau cover) and it seems lately I can "watch" the gas gauge drop. So I checked the last 1/2 tankfull and got 15.03. No change in driving pattern. 90% city. I'm not asking for advice on raising my mpg (I know theres plenty of those threads) just whether or not my on-board reading should be this far off.
