What is the difference between ethanol gasoline and 92-octane gasoline?

[MacPhoebe]

Ethanol gasoline and 92-octane gasoline differ in terms of anti-knock performance, price, and type. Anti-knock performance: 92-octane gasoline has better anti-knock performance. The isooctane content in 92-octane gasoline accounts for about 92%, while ethanol gasoline is a new alternative energy source formed by mixing fuel ethanol (processed from grains and various plant fibers) with regular gasoline in a certain proportion. The higher the octane rating, the better the anti-knock performance of the gasoline. Price: 92-octane gasoline is cheaper, while ethanol gasoline has higher production costs, making it more expensive than 92-octane gasoline. Type: The ethanol in ethanol gasoline is a renewable resource, making it more environmentally friendly and capable of reducing vehicle emissions. In contrast, 92-octane gasoline is a non-renewable resource and causes relatively more severe air pollution.
