What is the main composition of E-85 fuel?

75% ethanol and 25% gasoline
85% ethanol and 15% gasoline
90% ethanol and 10% gasoline
70% ethanol and 30% gasoline

The correct answer is: 85% ethanol and 15% gasoline

E-85 fuel is primarily composed of 85% ethanol and 15% gasoline. This particular blend is designed to be used in flex-fuel vehicles, which can run on a variety of ethanol-gasoline mixtures. The high ethanol content in E-85 offers several benefits, including a reduction in greenhouse gas emissions compared to traditional gasoline, as well as supporting domestic agriculture by utilizing corn and other feedstocks for ethanol production. The specific ratio in E-85, consisting of predominantly ethanol, helps provide an alternative energy source that can contribute to energy independence and sustainability. The gasoline component is included to ensure proper combustion and performance in engines designed to handle this fuel blend. This balance makes E-85 a popular choice for environmentally conscious consumers and those seeking alternatives to fossil fuels.
