Gasoline and diesel usage and pricing

Gasoline and diesel are both kinds of fuel used in cars and trucks. Gasoline is a light fuel made from petroleum, and diesel is a heavier fuel made from petroleum. When you fill up your car's tank, the gas station puts gasoline or diesel into it, depending on what kind of car you have. The price of gasoline or diesel can change from day to day and from place to place. That's because it is made from petroleum, and the price of petroleum changes every day. And, some places cost more than others because it costs more to get the fuel there.
