Gasohol is a fuel blend made from gasoline and ethanol, typically containing about 10% ethanol and 90% gasoline. Ethanol is a renewable resource often produced from crops like corn or sugarcane. This mixture is used in many vehicles as a way to reduce reliance on pure gasoline and lower greenhouse gas emissions. Using gasohol can help improve air quality and reduce pollution since ethanol burns cleaner than traditional gasoline. Many countries promote gasohol as part of their efforts to support sustainable energy sources and decrease carbon footprints, making it a popular choice for environmentally conscious drivers.
