what is e10

E10 fuel is a blend of regular unleaded petrol and between 9% and 10% ethanol. The ethanol content in E10 fuel increases the Research Octane Number (RON) to 94, making it a greener alternative to regular petrol. E10 is considered a safe and reliable fuel and is compatible with the majority of petrol-powered cars on the road today. However, older cars, particularly those built before 1986 or those using older technologies such as carburetors, are not designed to run on ethanol blends and should not use E10 fuel. High-performance vehicles may also not be suitable for E10 fuel. E10 fuel is being promoted as a way to reduce CO2 emissions, with estimates suggesting that it could reduce emissions by 750,000 tonnes per year, equivalent to taking up to 350,000 cars off the road. However, its important for motorists to always follow their vehicle manufacturer’s advice on the recommended fuel to use in their vehicle. If a car is not compatible with E10, using this fuel could result in poorer fuel economy and reduced engine performance. Its worth noting that E10 fuel is approved by the U.S. Environmental Protection Agency (EPA) for use in any conventional, gasoline-powered vehicle.
