I have reset my "Best Fuel" readout many times but I can't work out what criteria it uses to calculate a new best fuel. Sometimes it takes many trips and other times it displays a new reading within about 5 minutes. The other day I was coasting down a gentle hill and I reset it and it quickly displayed 6.2 L/100kms (45.6 mpg). Don't know why it displayed a new "Best Fuel" so quickly when other times it has taken days. I would be interested to hear from anyone who knows how it works.
In the meanwhile I have decided not to ever reset it again because 6.2 L/100kms is pretty impressive ... all a bit of a laugh.
