Hi Stevewa:
___I cannot say what others are doing in other forums but if you cannot trust the odometer in your car and the gallons pumped from your local station, relying on a trip computer is a far cry from accuracy if that is what you are really after.
___Along a similar note, take a look at the attachment of my Insight’s lmpg. Now take a look at the RHMDB with the tank over tanks calculated using the actual miles traveled/actual gallons filled. Afterwards, do you see any discrepancy?

___I will never use the FCD for an mpg calc but at least it tells you ~ what you received over a segment, tank, lifetime, whatever. It just so happens my Insight’s lmpg matches my actual to a tee for whatever reason?
___Jason’s RHMDB is a good overall view of the mileage received in any number of automobiles and with the rounding, the over reporting, under reporting, and incorrect reporting, I bet the list is within .5 mpg of actual when looking over a type of hybrid or non-hybrid. No guarantees of course but I can bet it is very very close.
___Good Luck
