Racing fuel is a specialized type of fuel designed for high-performance vehicles used in competitive motorsports. It typically has a higher octane rating than regular gasoline, which helps prevent engine knocking and allows for more aggressive tuning. This fuel can be formulated with various additives to enhance performance, improve combustion efficiency, and reduce emissions. Different types of racing fuel are available, including methanol, ethanol, and high-octane gasoline. Each type has unique properties that cater to specific racing conditions and vehicle requirements. Teams often choose their fuel based on factors like engine design, race regulations, and desired performance characteristics.
