What is gasohol a blend of?

1. 80% gasoline and 20% ethanol

2. 90% unleaded gasoline and 10% fermentation ethanol

3. 85% gasoline and 15% ethanol

4. 70% ethanol and 30% gasoline

The correct answer is: 90% unleaded gasoline and 10% fermentation ethanol

Gasohol is primarily a blend of gasoline and ethanol, and the correct composition that most commonly defines gasohol is 90% unleaded gasoline and 10% fermentation ethanol. This blend is designed to reduce air pollution and make use of renewable resources, as ethanol is often produced from biomass like corn or sugarcane. The 10% ethanol component in gasohol helps improve the octane rating of the fuel and can enhance engine performance while contributing to a reduction in greenhouse gas emissions compared to traditional gasoline alone. This composition caters to regulatory standards that promote cleaner fuels while also supporting agricultural systems that produce the ethanol. Other potential mixes might exist, but they don't define gasohol in the same widely accepted way as the 90/10 ratio does. The significance of gasohol lies in its ability to be a more sustainable and environmentally friendly alternative to traditional fuel, which has helped it become a popular choice in various markets.
