High-octane gasoline is a type of fuel designed to resist knocking or pinging during combustion in engines. It has a higher octane rating compared to regular gasoline, which means it can withstand greater pressure before igniting. This quality makes it suitable for high-performance vehicles, such as those made by Ferrari or Porsche, which require fuel that can handle their powerful engines. Using high-octane gasoline can improve engine efficiency and performance, especially in cars with turbocharged or high-compression engines. While it is often more expensive than regular gasoline, many drivers choose it to enhance their vehicle's power and longevity. However, most standard vehicles do not require high-octane fuel for optimal performance.
