Really?? Lets do the math.
Assumptions:
- Driving 12,000 miles per year
- Averaging 13 miles per gallon (that's what I get :eyes
- Paying $4.00 per gallon for regular unleaded
- Averaging 18 gallons to fill the tank
With these numbers you will save 5.83 gallons per year, which is $23.31.
If you're getting 16 MPG then the savings shrinks to $15.72 in a year.
If it's a worst case scenario and you are driving 15,000 miles per year and averaging 13 MPG you would save a whopping $29.14 per year.
