Gasoline station

A gas station is a place where motorists can go to fill up their vehicles with gasoline. In the United States most vehicles run on unleaded gasoline. This usually includes grades of 87, 89, and 91 octane with the higher numbers being the more pure blends and the higher quality. Most modern cars run on 87.

Leaded gasoline was largely replaced decades ago for environmental concerns.

Some stations also sell diesel gasoline, which has been common in trucks and at one time Mercedes vehicles.

At one time, such as back in the 1950s, gas stations were full service. The trend that spread from the 1970s was towards self service, which is the most common type today. There are still pockets on the east coast that are mostly full service.

Many gas stations have a convenience store that sells common automobile products, cigarettes, and food items. A large amount of the profit from gas stations come from the convenience stores. Some gas stations also have automotive repair shops.

The average profit on a gallon of gas in for a gas station owner is 23 cents.
