Armond,
First of ....great app!

I have a feature request. I am keeping track of both my wife's car and my motorcycle. Now the mpg calculated for a car is fine.......

However......unlike a car, for a motorcycle.....which typically has a tank capacity of 2-6 gallon, instead of calculating full tank to full tank......I typically use reserve to reserve (empty to empty if you are not familiar with reserve switch in a motorcycle)

Hence the difference between the two odometer readings must be divided by the volume of fuel purchased the previous time, not the current one.


The reason for doing this is that different gas nozzles sit differently in a motorcycle tank and fills up to different 'full' levels. While this happens in a car also....over a 10 or 20 gallon tank, that difference is negligible.......but over a 4 gallon tank like I have......those errors can start to be more significant.....hence reserve to reserve is a more repeatable way of making that calculation than full tank to full tank. Hence the odometer reading I note, is when I switched to reserve....not when I fill up the tank.

Any chance of including that as an option?
A 'Motorcycle with reserve switch' option?

Thanks!!!!
