Maxima Hi-Test Octane Booster Maxima Octane Booster is a high-performance 2-in-1 fuel treatment designed to increase octane levels while cleaning the entire fuel system. Formulated for use in high-compression or high-performance engines, it helps eliminate "knock" or "ping" caused by low-quality pump gas. This additive improves throttle response and combustion efficiency while removing carbon deposits from injectors, intake valves, and combustion chambers. It is safe for use in both 2-stroke and 4-stroke engines and will not harm oxygen sensors or catalytic converters. Features: Octane Enhancement: Increases fuel octane rating to prevent detonation in high-performance engines. Fuel System Cleaner: Detergent additives clean injectors and intake valves to restore lost power. Combustion Efficiency: Promotes a more complete fuel burn for improved throttle response and acceleration. Corrosion Inhibition: Protects fuel system components against the harmful effects of ethanol and moisture. Versatile Application: Safe for all carbureted and fuel-injected engines, including 2-cycle and 4-cycle. Concentrated Formula: Treats up to 10 gallons of gasoline for significant performance gains.
