what is super unleaded gas

Super unleaded gas, also known as premium unleaded or high-octane gasoline, is a type of gasoline that has a higher octane rating than regular unleaded gasoline. It typically has an octane rating of 97 to 99 RON (Research Octane Number), compared to the standard 95 RON of regular unleaded gasoline. The higher octane rating allows the engine to use a higher boost pressure and more aggressive settings to pump out a little more power. Super unleaded is often used by performance cars, but it is suitable for any petrol car. It is a cleaner-burning fuel option compared to traditional gasoline and can help reduce greenhouse gas emissions and dependence on fossil fuels. Super unleaded is a blend of regular unleaded gasoline and up to 10% ethanol, also known as E10, and is widely available across the United States. It can prove slightly more economical, allowing drivers to get more miles out of a tank of fuel, and some believe it can clean and maintain the internals of the engine. Additionally, super unleaded contains additives designed to keep the engine clean, which can lead to better long-term performance. While it may be worth trying a couple of tanks of super unleaded to see if the car feels different, the benefits may vary depending on the cars engine and usage.
