Nice little article here...for anyone interested..

Price increases generally occur when the world crude-oil market tightens and lowers inventories. We will discuss who controls the crude-oil market later. Also, growing demand can sometimes outpace refinery capacity. In the spring, refineries perform maintenance, which can place a pinch on the gasoline market. By the end of May, refineries are usually back to full capacity.
When you pump $20 dollars into your tank, that money is broken up into little pieces that get distributed among several entities. Gas is just like any other consumer product: There's a supply chain and several groups who are responsible for setting the price of the product. The media can sometimes lead you to believe that the price of gas is based solely on the price of crude oil, but there are actually many factors that determine what you pay at the pump. No matter how expensive gas becomes, all of these entities have to get their slice of the pie.
Let's look at where your money goes when you pay for gas:
Crude oil - The biggest portion of the cost of gas -- as of February 2006, that's about 59 percent -- goes to the crude-oil suppliers. This is determined by the world's oil-exporting nations, particularly the Organization of the Petroleum Exporting Countries (OPEC), which you will learn more about in the next section. The amount of crude oil these countries produce determines the price of a barrel of oil. Crude-oil prices averaged around $37 per barrel (1 barrel = 42 gallons or 159.6 L) in 2004 (Source: U.S. DOE). And, after Hurricane Katrina, some prices were almost double that. In July 2006, crude-oil prices averaged around $72 per barrel (1 barrel = 45 gallons or 159.6 L).
Sometimes, gas prices go up even though there is plenty of crude oil on the market. It depends on what kind of oil it is. Oil can be classified as heavy or light, and as sweet or sour (no one actually tastes the oil, that's just what they call it). Light, sweet crude is easier and cheaper to refine, but supplies have been running low. There's plenty of heavy, sour crude available in the world, but refineries, particularly those in the U.S., have to undergo costly retooling to handle it.
Refining costs - The refining of crude oil makes up about 10 percent of the price of gasoline. To learn more about oil refining, read How Oil Refining Works.
Distribution and marketing - Crude oil is transported to refineries, and gasoline is shipped from the refineries to distribution points and then to gas stations. The price of transportation is passed along to the consumer. Marketing the brand of the oil company is also added into the cost of the gasoline you buy. Together, these two factors account for about 11 percent of the price of gasoline.
Taxes - Taxes, including federal and local, account for about 20 percent of the total price of gas in the United States. Federal excise taxes are 18.4 cents per gallon, and state excise taxes average 20 cents per gallon. There may also be some additional state sales taxes, as well as local and city taxes. In Europe, gas prices are far higher than in America because taxes on gas are much higher. For example, gas prices in England have risen as high as $6 per gallon, with 78 percent of that going to taxes.
Station markup - While it isn't represented in the diagram above, of course some of the actual money you spend at the pump does go to the service station. Service stations add on a few cents per gallon. There's no set standard for how much gas stations add on to the price. Some may add just a couple of cents, while others may add as much as a dime or more. However, some states have markup laws prohibiting stations from charging less than a certain percentage over invoice from the wholesaler. These laws are designed to protect small, individually-owned gas stations from being driven out of business by large chains who can afford to slash prices at select locations.
