Unless you have an all-electric car (such as the Fisker Karma, made in Finland – developed with American tax monies), you are very aware of the fluctuating prices of gasoline. Depending primarily on the stock market and the price per barrel of crude oil in the various production areas around the world, you can see the pump price go up and down.

However, the price going up is far greater and more immediate than when the market indicates a drop. For instance (and I have been tracking this for a long time), the price per gallon will jump UP overnight by several cents when the stock market shows a rise, but when a drop is due it may take a number of days, even a week, to see that drop reflected at the pump. And, even then, the drop will be one or two pennies, not at the rate it went up!
