Octane Boosters

An octane booster is an additive that raises gasoline's octane rating to reduce knocking and allow engines to run at higher ignition timing; use it when your engine experiences knock, when running higher compression or boosted/turbocharged setups, or when recommended by a tuner for optimized performance

Choose based on the required octane increase, compatibility with your fuel system and emissions controls, and formulation for your use case (street, racing, or ethanol blends); consult your vehicle manual or engine builder and look for products that state the octane points added per tank or per gallon

Manufacturers typically state an approximate increase in pump octane number (PON) or research octane number (RON) — common increases range from a few points up to 10–15 points depending on concentration and dosage; actual gain depends on base fuel octane and tank size

Risks include potential harm to oxygen sensors, catalytic converters, fuel system seals, or engine deposits if the product contains incompatible solvents or is overused; avoid mixing incompatible additives and follow manufacturer dosage and vehicle emissions guidance

Use frequency depends on need: occasional use for knock mitigation or race events, or as directed by a tuner for sustained higher-octane operation; add the measured dose directly into the fuel tank before filling or as instructed on the product label to ensure proper dilution

Octane boosters enable higher ignition timing and more aggressive tuning in engines that were previously knock-limited, which can increase power or efficiency when paired with appropriate engine tuning, but they do not inherently improve economy or performance on engines already operating at optimal timing

Octane boosters span a wide price range from budget options under $20 to concentrated or race-oriented products over $100; well-known brands in the auto/racing space include BOOSTane, VP Racing, 104+, Snow Performance, and legacy fuel-additive makers such as STP
