Gasoline vs. Gasohol — What's the Difference?
By Urooj Arif & Fiza Rafique — Updated on March 29, 2024
Gasoline is a pure petroleum-derived fuel used in internal combustion engines, while gasohol is a blend of gasoline and ethanol, typically aiming to reduce emissions and reliance on petroleum.

Key Differences
Gasoline, a distilled petroleum product, is the traditional fuel for internal combustion engines, offering high energy content and efficiency. Gasohol, on the other hand, is a blend that incorporates ethanol, usually derived from agricultural products like corn or sugarcane, with gasoline. The most common blend is E10, which contains 10% ethanol and 90% gasoline, though other ratios like E15 and E85 exist for different uses and engine types.
The introduction of ethanol into gasoline (to create gasohol) serves multiple purposes: it reduces the overall environmental impact by cutting down on greenhouse gas emissions, decreases dependence on fossil fuels, and supports agricultural industries. While gasoline provides higher energy density, gasohol brings the benefit of being more environmentally friendly and renewable.
The performance of engines running on gasoline versus gasohol can vary. Gasoline engines are optimized for the higher energy content of pure gasoline, while gasohol can slightly lower fuel efficiency due to ethanol’s lower energy content. However, ethanol's higher octane rating in gasohol can improve engine performance by reducing knocking.
Economic factors also play a role in the gasoline vs. gasohol debate. Gasoline's price and availability are subject to crude oil market fluctuations, while gasohol, though potentially more stable due to the renewable nature of ethanol, can be influenced by agricultural market conditions and government policies related to ethanol production.
The transition from gasoline to gasohol reflects broader trends towards sustainable energy and reducing carbon footprints. While gasoline remains dominant in the global fuel market, the increasing use of gasohol and other biofuels is a step towards more sustainable transportation options.

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.

Common Curiosities
What is gasohol?
Gasohol is a blend of gasoline and ethanol, designed to reduce environmental impact and reliance on petroleum.
Why is gasohol considered more environmentally friendly?
Gasohol produces fewer greenhouse gas emissions compared to gasoline, due to the inclusion of ethanol.
Can all vehicles use gasohol?
Most modern vehicles can use E10 (10% ethanol blend), but higher ethanol content requires specially designed engines.
What are the economic implications of using gasohol vs. gasoline?
Gasohol can offer more stable pricing influenced by agricultural markets, whereas gasoline prices are tied to the volatile oil market.
Is gasohol less efficient than gasoline?
Yes, due to ethanol's lower energy content, gasohol can slightly decrease fuel efficiency compared to pure gasoline.
How does the ethanol in gasohol impact engine performance?
Ethanol's higher octane rating can improve engine performance by reducing knocking, though overall fuel efficiency may decrease.
