104+ Performance Max Octane Boost & Lead Substitute is a concentrated fuel additive that raises octane, reduces engine knock, and supplies a lead-substitute protective blend for vehicles running lower-octane gasoline.
If your engine hesitates, pings under load, or your vehicle is tuned for higher-octane fuel, 104+ Max Octane Boost can help your gasoline perform closer to what your motor needs. This formula is designed to boost octane rating, clean fuel-system deposits, and act as a lead substitute for engines that benefit from extra valve protection. Use it when you want to reduce detonation and restore smoother throttle response without switching to a different pump grade.
By increasing the fuel's effective octane, the additive helps the air-fuel mixture resist premature combustion (knock) under high load or advanced timing. That can translate into crisper acceleration and fewer hesitation events, especially in performance-tuned or older engines that experience pinging on lower-grade fuel.
104+ includes detergents that target fuel-system deposits, potentially improving fuel vaporization and combustion consistency. While results vary by vehicle and driving habits, regular use can help maintain injector and intake cleanliness that supports efficient operation.
The product is formulated to act as a protective lead substitute where additional valve seat or lubrication support is desirable, particularly in older engines designed for leaded gasoline. It is not a replacement for modern fuels engineered for catalytic converter-equipped vehicles, so follow manufacturer guidance for your specific model.
Simply add the recommended dose to a full tank of gasoline before fueling or directly into the fuel tank per the directions. For best effects, use it when filling up with lower-octane fuel, before spirited driving, or as part of routine fuel-system care.
Who is this for: 104+ Performance Max Octane Boost & Lead Substitute is aimed at drivers with performance-tuned vehicles, motorists experiencing knocking on lower-octane fuel, owners of older engines that may benefit from a lead substitute, and enthusiasts who want an easy add-in to support cleaner combustion and improved throttle feel. If you want a concentrated, U.S.-made additive to boost octane and offer supplemental valve protection while helping keep fuel-system deposits in check, this product is built for those needs. Always follow your vehicle manufacturer's guidance and the product's instructions when using fuel additives.

Q: Is this safe for catalytic converters?
A: When used as directed, it’s formulated to be compatible, but always follow vehicle manufacturer guidance for additives.
