not sure you did that right. it isn't at all obvious when fuel is in the denominator so lets flip it.

in your scenario car A(10mpg) gets .1 gpm (gallons/mile)
and car B(20mpg) gets .05 gpm.

so @ 10k miles a year they would use 1000 and 500 gallons respectively.

so 2% of that would be ~20 gallons and 10 gallons respectively "saved per year".
