How long have you driven your Elantra on one tank of gas? Meaning, it was full, you drove until you had to fill up 14+ gallons. How many miles (or kilometers converted into miles) did you go?

I hit just over 400 miles once, when my car was about 2 years old. Now, I'm lucky if I get much over 300 miles to a tank.
If you leave just a few minutes earlier, and drive 65, you'll save even more. Wind resistance increases exponentially as you increase speed. I think the hypermilers try to go 55mph tops.
Lately I've been driving speed limit or speed limit+5 because I got a speeding ticket in July and my gas mileage has increased 25-30 miles per tank (so like an extra gallon worth). Good stuff.
Just wanted to quote this and re-emphasize the role that air pressure plays in fuel mileage. When you are going slower, there is less air resistance pushing against the car. As you increase speed, it has a similar affect to driving up a hill. Slow and steady is how those hypermilers got 1000 miles out of a tank of gas on the new Sonata.

Does things like GPH, which can't be easily calculated. Your mpg ratings are only going to be as good as your cars sensors though (i.e. you use the wrong wheel/tire combo and it has no way to know that).
