If you drive a performance or enthusiast vehicle, small changes at the pump can make a noticeable difference. This 16 oz bottle of 104+ Performance Octane Boost comes in a six-pack to treat multiple fill-ups, helping prevent pinging and hesitation while cleaning injectors and combustion chamber deposits. It’s formulated to be safe with catalytic converters and oxygen sensors and is meant for use in gasoline engines to support consistent throttle response and stability under load.
104+ works by raising the effective octane rating of the gasoline when dosed as directed, which helps the fuel resist premature combustion (knock or ping). That stability allows the engine to operate closer to its designed timing and compression characteristics, restoring crisp acceleration and reducing micro-detonations that cause noise and stress.
Yes — the formula contains detergents targeted at dissolving carbon and varnish from fuel injectors, intake valves, and the combustion chamber. Regular use as part of scheduled maintenance can improve spray patterns, restore idle quality, and reduce hesitation during throttle transitions.
The 104+ formula is advertised as compatible with catalytic converters and oxygen sensors, meaning it’s formulated to avoid materials that could harm emissions hardware. As with any additive, follow dosing instructions and avoid mixing with other strong chemical treatments to reduce the risk of unintended reactions.
Each 16 oz bottle is concentrated to treat up to 18 gallons of gasoline; pour the bottle into a near-empty tank or during refueling so it mixes thoroughly. Buying the six-pack gives you multiple treatments for regular maintenance or repeated high-performance fueling sessions.
Who is this for: Drivers of high-compression, turbocharged, supercharged, or tuned gasoline vehicles who want to reduce knock, restore sharper throttle response, and keep fuel injectors cleaner. It’s also useful for anyone who experiences occasional pinging after low-octane fills or who prefers to maintain peak performance during spirited driving. Not intended for diesels or two-stroke engines; always follow your vehicle manufacturer’s recommendations and the product dosing instructions.
Q: How much gas does one 16 oz bottle treat?
A: One 16 oz bottle treats up to 18 gallons of gasoline when dosed as recommended.
Q: Is 104+ safe for catalytic converters and oxygen sensors?
A: Yes; the formula is designed to be safe for catalytic converters and oxygen sensors when used as directed.
