A Lucas Oil Octane Booster is a fuel additive designed to raise the octane rating of gasoline, helping high-compression engines resist spark knock, pinging, and premature combustion for smoother performance and improved fuel efficiency. It’s formulated to deliver significantly more octane boost than many competing products and is suitable for use in both fuel-injected and carbureted petrol engines, as well as being safe for turbos, oxygen sensors, and catalytic converters when used as directed. Adding the booster to your gas tank can promote a cleaner fuel burn with fewer unburned emissions and potentially better mileage, especially in demanding driving or performance situations. Typically one bottle is poured into the fuel tank before filling up to treat a specified volume of gasoline, making it a practical performance enhancer for cars, motorcycles, and other gasoline-powered vehicles that can benefit from higher octane levels.
