Gasoline

What’s Up With Gasoline Prices?
Changes in gasoline and diesel prices mirror changes in crude oil prices. The roller coaster rise and fall in gasoline and diesel prices over the last couple of years has tracked changes in the cost of crude oil. Those changes are determined in the global crude oil market by the worldwide demand for and supply of crude oil. Weak economic conditions in the U.S. and around the world in 2008 and into 2009 led to less demand and higher supplies which helped push prices down. Now, with the worldwide economic recovery underway, demand is on the rise again and prices rose earlier in the year. Recently, gasoline prices have generally followed crude oil prices down.
