Lucas Oil Octane Booster fuel additive — 15 oz Pack of 12, raises octane & reduces knock

Lucas Oil 10026-PK12 Octane Booster is a concentrated fuel additive that raises octane, reduces engine knock, and is safe for turbocharged engines, O2 sensors and catalytic converters.

Engineers and enthusiasts trust Lucas Oil's octane formula to improve combustion quality in both carbureted and fuel-injected engines. This 15 oz bottle, sold in a convenient pack of 12, delivers a potent dose designed for occasional performance tuning, high-compression motors, and situations where extra detonation resistance is needed. The formulation targets cleaner burns and stable operation without requiring engine modifications or complex tuning.

How does Lucas Octane Booster affect engine performance?

By increasing the fuel's resistance to premature ignition, the booster helps limit spark-knock and pinging under higher load or compression. That can enable more consistent power delivery and smoother acceleration when higher octane fuel is not available or when conditions demand extra knock protection.

• Raises effective octane rating for improved knock resistance
• Stabilizes combustion under heavy load and high compression
• Supports consistent throttle response during demanding driving

Is this product compatible with my engine and emissions equipment?

Lucas designed this octane booster to be safe for use with turbochargers, oxygen sensors and catalytic converters, making it suitable for modern, emission-equipped vehicles as well as older machines. It works in both fuel-injected and carbureted systems, but follow vehicle manufacturer guidance for additive use.

• Safe for turbocharged engines and common emissions components
• Formulated for fuel-injected and carbureted systems alike
• Intended for engines without specialized aftertreatment systems where applicable

How do I use Lucas Oil Octane Booster and how much should I add?

Application is straightforward: add the recommended amount directly into the fuel tank before refueling to ensure even mixing, or follow the directions on the bottle for precise dosing. Dosage varies by desired octane increase and tank size; use smaller amounts for mild improvements and higher amounts when extra protection is necessary.

• Add into fuel tank before filling for best dispersion
• Follow bottle directions for dose relative to tank size and desired octane lift
• Use periodically when higher-octane fuel isn’t available or during heavy loads

What other practical benefits can I expect?

Beyond octane uplift, Lucas Octane Booster promotes cleaner combustion which can reduce certain emissions and help maintain more consistent engine operation. While results vary by engine type and driving conditions, many users report fewer knock events and steadier performance during spirited driving or towing.

• Supports cleaner fuel burn for reduced deposits
• May help improve fuel economy in high-compression engines under some conditions
• Available in a 12-pack for workshops, racing teams or frequent users

Who is this for? Owners of high-compression engines, performance vehicles, or equipment that occasionally requires an octane boost will find this product useful. It's well suited for enthusiasts, racers, and mechanics who want an easy-to-use additive that is compatible with modern engine hardware and emissions components. The 12-bottle pack fits garages, fleets, and teams that need multiple treatments without frequent reordering.
