To travel 100 miles at each of those MPGs; 10MPG = 10 gallons of gas 12MPG = 8.33 gallons of gas 20mpg = 5 gallons of gas 30mpg = 3.33 gallons of gas 60mpg

To travel 100 miles at each of those MPGs;
10MPG = 10 gallons of gas
12MPG = 8.33 gallons of gas
20mpg = 5 gallons of gas
30mpg = 3.33 gallons of gas
60mpg = 1.67 gallons of gas
1,000mpg = 0.1 gallons of gas
So moving from 10-12mpg saves 1.67 gallons per hundred miles. Moving from 20-30mpg saves the same. At 60mpg, you're only using 1.67 gallons of gas, so there's no improvement to MPG that will save more than that. Nearly all the gains to actual fuel consumed will come from increasing the worst offenders rather than e.g. trading in Corollas for Pruises.
Also a good demonstration why the CAFE standards and other government fleet minimums are actually pretty effective at lowering fuel demand.
