Try doing the rest of the math. 33mpg -> ~1.52 gallons 50mpg -> 1 gallon for a 50 mile trip So going from 33mpg to 50mpg saves half a gallon. 13mpg -> 3.84 g

Try doing the rest of the math. 33mpg -> ~1.52 gallons 50mpg -> 1 gallon for a 50 mile trip So going from 33mpg to 50mpg saves half a gallon. 13mpg -> 3.84 gallons for a 50 mile trip 17mpg -> 2.94 gallons for a 50 mile trip .9 gallons saved. So in your scenario, going from 13mpg to 17 saves more gas than switching from 33 to 50.

If you're just comparing percentages, then yes 0.9 > 0.5. However, overall the comparison doesn't stand up. 1 gallon for 50 miles vs 2.94 gallons, the 50 mpg is what is saving more gas, therefore it wins.
