Here is a little fuel cost comparison table that I whipped up for a person who drives the average 12,000 miles per year.
If you change from 15 mpg to 45 mpg your will save (2,400 - 800) = $1,600/year or $133/month.
I included up to 120 MPG, as motorcycles commonly get 60 to 100 mpg and there are some scooters in the 100 to 120 mpg range.
