Fuel/Cost Savings of Improving Fuel Economy from 12->15 mpg = 30->60 mpg
Consumer tip-of-the-day: increasing efficiency of fuel economy on a miles-per-gallon scale is not linear, as more miles-per-gallon (mpg) are initially better for your wallet and the planet than you might expect, and eventually trail off with diminishing returns...
