2nd fillup and MPG incorrect. Entered 133.1 miles and 8.69 gallons and when I ''save'' it shows 13. miles and 1.5 MPG it will not allow the proper mileage to be entered.
If you need to change the tracking method of your entire fuel-up history, it's best to create a new vehicle with your preferred tracking method and use import/export to add your previous fuel-ups.
The tech was right I was using the ''odometer'' reading to track fuel and when I tried to enter 133.1 miles it appeared as 13 miles. I would have thought the odometer would have been the correct way to track, but, apparently miles is the correct setting. I changed it and all appears correct now.
