So, I slowed down (one stretch has an 80 MPH posted limit) to 70, added cruise, started drafting and ran without A/C. All this got me to just shy of a miserable 20 MPG. Dang! Now what?
An 11% gain is a pretty big gain - nothing to laugh at or be disappointed with at least....

Say you drive 20,000 miles per year

@ 18mpg, that's ~1111 gallons of fuel
@ 20mpg, that's 1000 gallons of fuel
a difference of 111 gallons

At $3.445 (national average 4/18 according to AAA) that 2mpg difference saves you ~382 per year.

Maybe if you air up your tires - you might be able to get closer to 21mpg (~$546 savings over 18mpg)

Extraordinary mileage (or anything for that matter) is for those that put in extraordinary effort in doing so <-- remember, 90% perspiration - some of that will be literal

EDIT: Doh! Old thread!!!
Cars have not created a new problem. They merely made more urgent the necessity to solve existing ones.
