We all know this vehicle isn't cheap on fuel. Is it just me, or are others surprised how some are willing to invest serious coin to modify something or buy a different vehicle to get a few more MPGs...have you ever calculated the break even point on that cost?

Let's assume you do some modification that costs $1,000,and it increases MPG from 16 to 20 MPG....a full 25% increase, which is doubtful.
16MPG x 22.5 gallons = 360 miles per tankful
20MPG x 22.5 gallons = 450 miles per tankful
If fuel is $2.95/gallon, you gain 90 extra miles per full tank
90 miles � 20MPG = 4.5 gallons to travel that far
$2.95/gallon x 4.5 gallons = $13.27 saved on a full tank
Another way of looking at it is you save .029/mile.....

$1,000 �$13.27 = 75.35 tankfuls....for most, filling up every 2 weeks, that would take 3-4 yrs to just break even.....and only then would you begin saving any money

Maybe for tracking MPG, you might look into registering at fuelly.com. It's kinda fun. Here's my VX:
