Gas buying strategies.

I live in the communalist state of California.  The cost per gallon is averaging  $4.01 per gallon.  Effective today,  my wife and I will buy gas nearly every time we drive by a gas station as long as fuel is on the increase.  Fuel is increasing at the rate of 20 cents a gallon every week.  Be advised.  

When gas prices are on the decline,  it is recommended that you buy fuel as seldom as possible.
