OK, so just for fun.

I took the difference from start to current miles as the miles recorded. Only used entries that had 2000 or more recorded miles.

Calculated the total gas used for each entry by dividing the miles recorded by the avg gas milage listed.

Seemingly there were no invlaid entries with abvious errors, like 2 MPG, etc.

Summed all the miles recorded and gas used for valid entries and did the quick avg MPG calculation.


HCHII CVT
170 entries used according to rules above
1,120,679 total miles
23,373 total gal
47.9 MPG avg

Prius II
457 entries used per rules
4,742,127 total miles
97,163 total gal
