VP Racing Madditive Octanium Leaded Octane Booster – 946ml • 2855
High-performance petrol octane booster for petrol-powered race cars, track vehicles, modified performance engines and off-road motorsport applications, formulated to increase fuel octane, help combat engine knock and support demanding engine operating conditions.
VP Racing Octanium is a concentrated fuel additive developed for performance applications where increased octane resistance is desirable, particularly in engines running higher compression ratios, increased ignition advance or additional boost pressure.
By increasing the fuel's resistance to uncontrolled combustion, Octanium helps reduce the risk of detonation, commonly experienced as engine knocking or pinking, under demanding operating conditions.
The formula is capable of increasing petrol octane by up to 8 numbers (80 points) when used at the manufacturer's specified treatment ratio, although the actual increase depends on the base fuel and application.
Higher-octane fuel can help suitably configured performance engines operate more consistently under load, particularly where the engine's tuning and fuel requirements are matched to the resulting octane rating.
Octanium also contains fuel-system cleaning additives formulated to help remove injector deposits and reduce gum and varnish accumulation within the fuel system.
Its concentrated formulation combines octane enhancement with fuel-system cleaning benefits in a convenient 946ml container.
VP Racing Octanium can also function as a lead substitute in suitable petrol engines, making it useful for certain older competition and performance engine applications.
One 946ml bottle treats up to 38 litres of petrol at the manufacturer's full-strength racing treatment ratio.

Application Advice: Octanium is intended primarily for petrol engines used in racing, off-road competition and performance applications where increased fuel octane is required. It is particularly relevant to modified engines with increased compression, advanced ignition timing or higher boost pressures.
MX-5 Performance Applications: Suitable for consideration in Mazda MX-5 performance and motorsport builds, including modified naturally aspirated, turbocharged and supercharged petrol engines, where the fuel specification and engine setup are compatible with the product.
Important – Emissions Equipment: The full-strength racing dosage is intended for engines without catalytic converters or oxygen sensors. Vehicles retaining emissions-control equipment require the lower treatment ratio specified by VP Racing. Octanium Unleaded is the alternative product developed specifically for broader compatibility with emissions-controlled petrol engines.
How to Use: Add the required quantity of Octanium to the petrol tank in accordance with the manufacturer's treatment instructions. For full-strength racing use, one 946ml bottle treats approximately 38 litres of petrol. The appropriate treatment quantity depends on the fuel volume, required octane increase and the vehicle's emissions-control equipment.
Performance Advice: The maximum octane increase depends on the starting fuel and treatment ratio. Increased fuel octane does not automatically increase engine power unless the engine's operating conditions or calibration can take advantage of the improved knock resistance.
Handling & Storage: Keep the container securely closed and protected from direct light. Do not freeze. Avoid contact with painted vehicle surfaces and light-coloured plastic containers. Keep away from ignition sources and use in accordance with the safety information supplied with the product.
Other Items to Consider: Suitable performance engine oil, fuel filters, spark plugs, fuel-system servicing products and VP Racing fuel-handling accessories.
Why VP Racing? VP Racing Fuels specialises in performance fuels, octane boosters and specialist motorsport products developed for demanding engine applications. Octanium provides a concentrated octane-enhancement solution for enthusiasts and competitors seeking increased resistance to detonation and improved fuel-system cleanliness.
