Matt -
Hrmmmm, interesting POV. Here's another one from a $ POV. Assuming $3.50 per gallon :
New (Ecomodder) MPG : 40+
Usual fill-up : ~5.5 gallons (1/4 tank to 3/4 tank)
New fill-up Miles : 40 MPG * 5.5 gallons = 220 Miles
Cost : 5.5 gallons * $3.5 = $19.25
Old (pre-Ecomodder) MPG : 30+
Gallons to go 220 Miles : 220 Miles / 30 MPG = 7.33 gallons
Cost : 7.33 gallons * $3.5 = $25.67
Cost Difference : $25.67 - $19.25 = $6.42 => ~$6.50 for each fill-up.
---------------
Now, let's look at a year. I project about 20,000 miles this year :
20,000 / 30 MPG => 666.67 Gallons
20,000 / 40 MPG => 500.00 Gallons
Difference = 666.67 - 500.00 = 166.67 Gallons saved per year
Money Saved Per Year : 166.67 * $3.50 = $583.45
