(Why such a large discrepancy between the two countries' highway figures? Hmmm.)
View graphs and complete tank-by-tank and cumulative mileage for both Firefly #1 (retired) and #2 (Blackfly).
1 L = 3.7854118 US gallons = 4.54609188 imperial gallons
1 mile = 1.609344 kms
Best and worst stats are for single fill-ups on either Firefly #1 or #2 and have to be taken with a grain of salt, since I don't typically drive to "E" before refilling (e.g. if I drive a 300 km highway trip, I might fill up at the end to get a "highway only" reading). The smaller the refill, the greater the margin of error.
Best was for Firefly #2 - a 431 km distance, a mix of city and rural highway driving. This was an experiment in pulse and glide (though all the trips were legitimate), just to see if I could break the 100 mpg (US) barrier.
Worst was for Firefly #1 - just 100 km of city driving.
Previous 3 is for Firefly #2 - cumulative figures from the last 3 fill-ups. This gives a more accurate snapshot of how things are going recently. I typically fill up once a month.
All: a total of all fuel consumption for Firefly #2 since I got the car. To date, 11341 km and 436.5 L.
When I fill up, I aim for consistency by always filling to the same point - i.e. where I can see fuel at the top of the filler neck. This is usually several "clicks" past where the pump wants to stop at first.
Retired stat: City - cumulative urban fuel consumption for fill-ups that were exclusively sub/urban driving. To date, 1567 km and 86.0 L. (I don't get as many fill-ups that meet these criteria, because I don't do much exclusively city driving between highway trips). Retired this stat after May 3/06 fill-up.
Retired stat: Hwy - a calculation of my cumulative highway fuel consumption where the trip length (before refueling) exceeds 200 km. To date, 4216 km and 196.1 L. Retired this stat after May 3/06 fill-up.
Retired stat: Mixed - cumulative fuel consumption where driving is a mix of both sub/urban and hwy. To date, 4771 km and 243.0 L. Retired this stat after May 3/06 fill-up.
Of course, this all assumes that my odometer is accurate (I should really check that - [EDIT: I have verified my odometer), and that the gas pumps report accurate volumes.
