DescriptionThe whole story▼
The Bardahl Racing Octane Booster Sébastien Loeb raises the octane rating of petrol by up to 5 points, delivering cleaner combustion, stronger power delivery and genuine protection for valves and valve seats. At 300 ml it is sized for convenient use at the track or on the road, and its straightforward dosing means consistent results every time you fill up.
Key Features
- Raises octane rating by up to 5 points depending on the base fuel used, unlocking the full potential of the engine's ignition timing.
- Optimises combustion efficiency for measurably stronger power output and improved throttle response.
- Protects valves and valve seats against wear and carbon build-up, extending the service life of critical engine components.
- Reduces engine deposits, keeping fuel passages, injectors and combustion chambers clean over time.
- Compatible with all petrol engines — naturally aspirated, turbocharged, carburetted and fuel-injected.
- Simple application: pour into the tank before fuelling to ensure thorough mixing with the incoming fuel.
Performance and Engine Protection
Modern high-performance engines are mapped to exploit every fraction of available octane rating. Even a modest shortfall between the pump fuel and the engine's designed octane requirement can trigger knock-retard, costing power and generating excess heat. The Bardahl Racing Octane Booster Sébastien Loeb addresses that gap directly, restoring the margin the ECU needs to hold optimal ignition advance under full load. The result is power that the mapping already expects — released rather than invented.
At the same time, the formulation carries Bardahl's signature valve-seat protection chemistry. On engines without hardened valve seats — including many older and competition-oriented units — this additive layer replaces the lubricating role once played by leaded fuel, significantly reducing recession wear during sustained high-rpm use.
Track and Road Use
Whether you are chasing lap times or simply want the most from a spirited road ride, a raised octane ceiling allows the engine to breathe freely at peak load. Add the 300 ml bottle to the tank before your next fill to let it blend thoroughly, and the improvement is immediate. The compact format makes it easy to carry in a toolkit or pit bag for on-the-spot use at circuit days.
Fitment and Compatibility
Suitable for all petrol (gasoline) engines including motorcycles, cars and other four-stroke applications. Compatible with carburetted and fuel-injected systems. Not intended for use in diesel engines. Works with standard and premium pump fuels as well as racing-grade unleaded petrol.
