Amsoil Octane Boost
Increases octane up to three numbers for maximum power and efficiency. Designed to improve startup performance and eliminate engine ping or knock for increased power during low-rpm operation. Contains detergents that help combustion chambers and fuel-delivery systems maintain cleanliness for optimum performance. At recommended treat rate, does not harm catalytic converters or oxygen sensors. When added to 4-6 gallons of fuel, increases the octane of gasoline up to three numbers. Helps improve power and eliminate performance-robbing and potentially damaging engine knock or ping. Reduces the need for knock-detection systems to compensate for engine knock, ensuring maximum low-rpm power and performance.
