Same as fox. I reset one trip every fill and the other gets reset at the beginning of a major trip. There's no way I can comply with your rules which are quite frankly silly.
Averaging around 25mpg at the moment.
Reset after each refill or before long journey are not representative of real life consumption. Although measurements using other applications are useful and under certain conditions more accurate, in order to keep the thread tidy only posts with a photo of the trip computer will be included in the leader table.
