That list must be out of date -- some of those countries I know for sure are not correct.
I own a Ford with a V6 and I get between 19 to 22 mpg overall average for gasoline mileage.
But you know, the last few times I went to the gas station, every pump had a car at it, and sometimes there were lines! It seems like we are using more gas, not less.
The gas prices suck.....no doubt. But it could be worse I guess.
I don't get the complaints about gas prices. Gas in Canada is, on average, about $4 USD a gallon. Gas in the UK is on average about $8 USD a gallon. Don't even ask about Iceland... fact is we have some of the lowest gas prices in the world here.
