Reduce engine hesitation, detonation and pinging caused by low quality, low octane fuels while increasing power and performance with Rislone Octane Booster. Formulated with the highest concentrate of MMT Methylcyclopentadienyl Manganese Tricarbonyl permitted for use on the street, Rislone Octane Booster will restore lost horsepower and performance by increasing the fuel octane rating by up to 20 points or 2 total rating numbers. Higher octane fuels allow engines to run optimum ignition timing without dangerous detonation or pinging. This will help to improve power, throttle response and economy while also reducing emissions.

Rislone Octane Booster is suitable for all petrol engines including high performance racing and off road vehicles, vintage and classic vehicles and even the family grocery getter. It is safe to use with all unleaded petrol, ethanol blends (e10, e15, e85) and racing fuels. Rislone Octane Booster wont damage oxygen sensors or catalytic converters. 1 bottle of Rislone Octane Booster will treat up to 75L of petrol. For smaller engines, use ¼ bottle for every 19L.
