104+ Performance Octane Boost fuel additive — 16 oz bottle, 6-pack; raises octane & cleans injectors

104+ Performance Octane Boost is a concentrated fuel additive that raises octane, helps reduce engine knock, and cleans fuel system deposits in one 16 oz treatment.

If you own a performance-oriented car or just want smoother combustion and fewer ignition issues, this 16 oz bottle of 104+ delivers a targeted octane increase while helping clear injectors and intake deposits. Sold as a six-pack, each dose is formulated to treat up to 18 gallons of gasoline, making it easy to use before spirited drives, track days, or whenever your engine shows hesitation. The formula is labeled safe for catalytic converters and oxygen sensors so you can add it without worrying about emissions hardware compatibility.

How does 104+ Performance Octane Boost change engine performance?

Raising the octane rating helps resist premature detonation (knock), letting the engine run closer to its intended timing and performance. In many vehicles that experience pinging under load, an octane lift can restore smooth acceleration and prevent timing setbacks from the ECU. The additive also includes detergents that help clear deposits that reduce fuel spray quality.

• Increases fuel's resistance to knock for steadier combustion.
• Helps restore responsive throttle feel during acceleration.
• Contains cleaning agents to improve injector spray patterns.

Will this product protect my emissions system and sensors?

104+ is formulated to be safe for catalytic converters and oxygen sensors when used as directed, avoiding harm to emissions components. That means you can treat fuel without sacrificing factory exhaust monitoring. Always follow the recommended treat rate to prevent overuse.

• Safe for catalytic converters and O2 sensors per product labeling.
• Designed for single-dose use in up to 18 gallons of gasoline.
• Use per instructions to maintain emissions equipment compatibility.

How do I use a 16 oz bottle — and when should I add it?

Simply pour one 16 oz bottle into a fuel tank containing up to 18 gallons of gasoline, then fill as normal to mix. Use before performance driving, when you notice pinging, or after running low-grade fuel to help restore combustion stability. Regular use can help maintain cleaner injectors between service intervals.

• One 16 oz bottle treats up to 18 gallons of gasoline.
• Pour into tank before refueling for best dispersion.
• Use prior to spirited driving, track events, or when knock appears.

Will this improve my fuel economy or just power?

While the main benefit is improved combustion stability and reduced knock, cleaner injectors and better burn can produce modest gains in throttle response and fuel efficiency. Results vary by vehicle, driving style, and existing fuel system condition. Consider it a combined performance and maintenance step rather than a guaranteed mileage fix.

• Can improve throttle response by enabling correct ignition timing.
• Detergents may increase efficiency by restoring spray patterns.
• Actual MPG gains depend on vehicle and driving conditions.

Who is this for: 104+ Performance Octane Boost is aimed at drivers of high-compression and turbocharged cars, automotive enthusiasts who push their vehicles hard, and anyone who wants a convenient way to reduce engine knock and clean fuel injectors. It’s also suitable for owners concerned about emissions hardware compatibility who want a safe, single-dose boost before spirited driving or track use. If your vehicle shows pinging under load or you use lower-octane fuel than recommended, this product provides a practical step to improve combustion quality and maintain fuel-system cleanliness.
