How much energy can gasoline produce?

Gasoline has a high energy density, meaning it can store a lot of energy in a small volume. The energy content of gasoline is approximately 132,500 British thermal units (Btu) per gallon or 33.7 megajoules (MJ) per liter. This means that burning one gallon of gasoline releases about the same amount of energy as burning 132,500 cubic feet of natural gas or 1,500 pounds of coal.

The energy content of gasoline varies slightly depending on its composition and octane rating. Higher-octane gasoline contains more energy per gallon than lower-octane gasoline. However, the difference in energy content between different grades of gasoline is relatively small. For example, the energy content of 87-octane gasoline is about 132,000 Btu per gallon, while the energy content of 93-octane gasoline is about 133,500 Btu per gallon.

Gasoline's high energy density makes it an ideal fuel for vehicles and other mobile applications. It is also a relatively inexpensive fuel compared to other energy sources. However, gasoline is a non-renewable resource and its combustion releases pollutants into the atmosphere, which can contribute to climate change and air pollution.
