for every 10,000 miles, 80 mpg=125 gallons needed=$250

so, every 10,000 miles saves $150

to save $2/day in gas, you would have to drive 10,000 miles every 2 1/2 months ($2/day x75 days=$150), which means you drive 48,000 miles per year. most people arent putting anywhere near that kind of mileage their cars. for those that do, yeah, it could make a difference.

...and taking that 80 mpg vehicle another 30 mpg to 110 mpg would require 90.9 gallons, saving only $68 every 10000 miles. as was said, diminishing returns are a bitch.
