The VP Racing Fuels 2855 is a concentrated octane booster formulated for off-road racing applications where maximum engine performance is required. Sold in a 32 oz bottle, it raises octane up to 8 numbers (80 points), eliminating knock and ping that rob power and damage engine components under high-load conditions. The formula also functions as a lead substitute and actively cleans fuel injectors while dissolving gum and varnish deposits. Each bottle treats up to 10 gallons of fuel. This product is intended for use by mechanics, racing technicians, and experienced operators working with carbureted or fuel-injected off-road engines.
This octane booster is designed for off-road racing environments including dirt bikes, ATVs, karts, and competition engines that run without catalytic converters or oxygen sensors. It is blended specifically to improve throttle response and acceleration in high-performance applications. The formula addresses fuel quality variations that are common when sourcing pump gasoline for competition use. It is not suitable for street-legal vehicles equipped with catalytic converters or O2 sensors, as it can damage those emissions components.
Formulated for off-road racing applications in engines without catalytic converters or O2 sensors. Do not use in vehicles equipped with catalytic converters or oxygen sensors.
Add the correct dose to the fuel tank before filling with gasoline to ensure thorough mixing. This product is a fuel additive and does not require mechanical installation, but handling should follow standard chemical safety practices including use of gloves and eye protection. Keep away from open flame during use. This product carries a California Proposition 65 warning for cancer and reproductive harm.
