Homonym: E10 (Fuel)
E10 is a type of fuel that contains 10% ethanol and 90% gasoline. Ethanol is a renewable biofuel made from plants, such as corn or sugarcane. The addition of ethanol helps reduce greenhouse gas emissions and can improve engine performance in some vehicles.
Many countries have adopted E10 as a standard fuel option to promote cleaner energy sources. However, not all vehicles are compatible with E10, so it's important for drivers to check their owner's manual or consult with their vehicle manufacturer to ensure it is safe to use.
