Gasoline varies by grade Three main grades of gasoline are sold at retail gasoline refueling stations: Regular Midgrade Premium Some companies have different names for these grades of gasoline, such as unleaded, super, or super premium, but they all indicate the octane rating , which reflects the antiknock properties of gasoline.

Frequently asked questions What do I pay for in a gallon of regular gasoline and diesel fuel? How much ethanol is in gasoline, and how does it affect fuel economy? The United States is the world's leading consumer of petroleum; in , Americans used 7,, barrels of oil per day. Petroleum is formed from the remains of plants and animals that have been held under tremendous pressure for millions of years.

Ordinarily, this organic matter would decompose completely with the help of scavengers and aerobic bacteria, but petroleum is created in an anaerobic environment, without the presence of oxygen. Over half of the world's known crude oil is concentrated in the Persian Gulf basin. Other major areas include the coasts of Alaska and the Gulf of Mexico. Petroleum products, including gasoline, are primarily a mixture of hydrocarbons molecules containing hydrogen and carbon molecules with small amounts of other substances.

Crude oil is comprised of different lengths of hydrocarbon chains, with some short chains and some very long chains. Depending on how much the oil is broken down, or refined, it may become any number of products. In general, the smaller the molecule, the lower the boiling point. Therefore, gas, with very small chains of one to five carbons, boils at a very low temperature. Gasoline, with carbons, boils at a slightly higher temperature.

Gasoline is one of the products derived from distilling and refining petroleum. Compounds of organic lead were added to gasoline in the past to reduce knocking in engines, but due to environmental concerns this is no longer common. Other chemicals are also added to gasoline to further stabilize it and improve its color and smell in a process called "sweetening.

A fractional distillation tower is a huge unit that may hold up to , barrels of crude oil. The vapors rise into the fractionating column, which may be as tall as feet 46 m. The vapors cool as they rise through the column. Since the boiling points of all the compounds differ, the larger, heavier molecules will condense first lower in the tower and the shorter, lighter molecules will condense higher in the tower.

How likely is gasoline to cause cancer? So what should you do with old gas? Gasoline, new or old works well for killing weeds.

Use a dish detergent bottle. Good for sidewalks and edges. Gasoline is one of the most flammable substances there could be. Nothing does a better job at catching a flame than some gas.

Do this at your own risk. But many have good fortune with using the older gasoline is also, older lawnmowers. Some use it for older trackers as well. It works fine for some, and others suggest not doing it. One option is you could pour it in a flat pan and put it in the hot sunlight.
