Friends: 0 |  Computer vs Actual MPG Does anybody check the computer calculation for MPG to see how accurate it is? I checked mine and the computer appears to be overstating the MPG by about 7 Miles. (You know how to check MPG manually right? Fill tank - Set Trip Odometer to 0 - Drive around - Fill tank back up and divide your Odometer miles by the amount you added to the tank.) |

Friends: 0 | Re: Computer vs Actual MPG Our indicated ios consistantly 3 to 4 MPG better than actual. It's misleading. Should be fixed. I've had to stop telling people I get 50 MPG. |
