Point taken...In that case, you're questionnaire is tedious and we shouldn't be interested in learning if/how to improve MPG's from each other.
Oh wait. It can't be improved. Jerry Lemond told me so.
I'd just like to know how a few people have posted 20+MPG claims over the years. I guess if you drive down the mountains, don't hit stoptlights, have the wind behind your back, and don't fill the tank ALL the way back up, anything is possible!
FWIW: I won't post to the fuelly site. Though it's nice, I can't see it being enlightening. Again, not enough detail. All I do is reset the trip odo after every fill-up. Take the mileage and divide by gals of gas.
I'm up to 15.5 with 90% city driving. And most are short trips in the 5m range. Hard to get great mpg doing that, right?
