Ethanol vs. Gasoline — What's the Difference?
Edited by Tayyaba Rehman — By Fiza Rafique — Published on October 1, 2023
Ethanol is an alcohol-based fuel derived from plants like corn and sugarcane. Gasoline is a petroleum-based fuel refined from crude oil.

Key Differences
Ethanol has a higher octane rating than gasoline, which can potentially offer better engine performance. However, gasoline has a higher energy density, meaning you get more energy per unit volume, leading to longer driving ranges. Both fuels have pros and cons in terms of performance.

Ethanol is a biofuel made primarily from corn or sugarcane, making it renewable. Gasoline, on the other hand, is derived from fossil fuels, primarily crude oil, which is non-renewable. Both fuels are used in internal combustion engines, but they come from fundamentally different sources.

Ethanol can be mixed with gasoline to produce a hybrid fuel called E85, which contains up to 85% ethanol. This blend aims to combine the best attributes of both fuels. Gasoline, when mixed with ethanol, can offer some of the environmental benefits of ethanol while retaining the energy density of gasoline.

Ethanol is considered to be environmentally friendlier than gasoline. It emits fewer greenhouse gases and other pollutants when burned. Gasoline releases more harmful emissions, contributing more to air pollution and climate change. However, both fuels have some level of environmental impact.

Gasoline
Gasoline () or petrol () (see the etymology for naming differences and the use of the term gas) is a transparent, petroleum-derived flammable liquid that is used primarily as a fuel in most spark-ignited internal combustion engines. It consists mostly of organic compounds obtained by the fractional distillation of petroleum, enhanced with a variety of additives.

Ethanol
Ethanol (also called ethyl alcohol, grain alcohol, drinking alcohol, or simply alcohol) is an organic chemical compound. It is a simple alcohol with the chemical formula C2H6O. Its formula can be also written as CH3−CH2−OH or C2H5OH (an ethyl group linked to a hydroxyl group), and is often abbreviated as EtOH. Ethanol is a volatile, flammable, colorless liquid with a slight characteristic odor.

Gasoline
A highly volatile mixture of fluid hydrocarbons, obtained mostly from petroleum, as also by the distillation of bituminous coal. It is used as a fuel for most automobiles and for many other vehicles with internal combustion engines. The gasoline of commerce is typically blended with additives to improve its performance in internal combustion engines. Gasoline was also used in the early 1900's in making air gas, and in giving illuminating power to water gas. See Carburetor.
