USA Average 15,000 miles a year
Average USA car 20 MPG = 750 gallons a year
$2.50 to $4.00 a gallon = $1.50
$1.50 x 750 gallons =$1125.00 per year
But this might only last from May to September or 40% of the months of the year. So now we are talking $450 a year. If you start now and save $1.89 a day for the remaining 237 day in the year, you should be fine.
Unrest in the Middle East always results in higher oil prices.
That really puts it into perspective. A bit more than one month of our morgage and people are complaining. Overhere in Italy (military) we pay close to 6 dollars a gallon.
