I know this sort of thing has come up before, but I am stunned by the mileage some of you are getting... Are you basing your numbers on the indicated tank mileage or calculated with miles and gallons? Do you baby the car to get that kind of mileage? Is it mostly highway?

The top value in the database right now is one entry that seems suspicious to me:
jocular_chen - 49.7 mpg over exactly 1000 miles (and just one tank of exactly 20 gallons?) - this one seems fishy to me. The tank only holds 17.2 gallons! Are these canadian figures or something (using imperial gallons)? maybe this was a test entry that someone made?

The rest of the entries seem more reasonable, but I really don't know how you all do it! I am curious about the ages of the top 10 - solely because I am curious if they are older, less agressive drivers. I hope this doesn't offend anyone!

I was getting about 37, but now that it is getting colder out, my numbers are dipping lower. My last tank (32.8) was almost as bad as the first tank I had (32.6 - which I blamed on my noob-ness when it came to hybrids). I think part of it is that I am not focusing on driving it like a hybrid as much as I used to, and I haven't been taking any long trips (which seem to boost the numbers).

Thanks!
