Please correct me if I am wrong.

a) 12MPG at $5 per gallon over five years with 15000 miles per year
is a result of $31250

b) 24 MPG, everything else the same, is $15625
c) 48 MPG, everything else the same, is $7812

going from 12MPG to 24MPG gets $15625 back to you over five years

going from 24MPG to 48MPG gets $7812 back to you over five years

going from 48MPG to 96MPG gets $3906 back to you over five years

Yes I realize that if gasolene gets to $10 per gallon, savings will double.

*************

point is, hypermiling mpg savings is mathematically not paying back at a certain point (personally decided). In five years it is a good time to switch to PHEV, to save more than ecomodding, as maybe some international company will have it right.
