MILWAUKEE (June 27, 2011) Ideal for use in areas where premium fuel is not available, Screamin' Eagle® Super Octane Boost (P/N 94867-10, $4.95) from Harley-Davidson® Genuine Motor Accessories provides a 3 RON (Research Octane Number) boost to the posted pump gas octane. Use of higher-octane gasoline may reduce engine pinging and heat, and improves performance in higher-compression engines. Formulated with a powerful detergent, Octane Boost effectively cleans fuel injectors, carburetors, and intake valve and combustion chamber deposits with just one treatment. One four-ounce bottle of Octane Boost treats one motorcycle tank of fuel. Safe for use with catalyst and oxygen sensor equipped bikes, Screamin' Eagle® Super Octane Boost is the only octane additive tested and approved by Harley-Davidson Motor Co., for use in Harley-Davidson motorcycles.
