High-performance fuel is a type of fuel designed to enhance the efficiency and power output of engines, particularly in high-performance vehicles like sports cars and racing cars. This fuel typically has a higher octane rating, which helps prevent engine knocking and allows for more aggressive tuning of the engine for better performance. These fuels often contain additives that improve combustion, reduce engine deposits, and enhance overall engine cleanliness. Common examples of high-performance fuels include premium gasoline and racing fuel, which are formulated to meet the specific needs of high-performance engines, ensuring they operate at their best.
