This listing is for a brand new case (12 Quarts) of Genuine Honda GN4 10w30 engine oil. Honda set the standard for motorcycle oil when it introduced GN4 way back in 1975. They selected the highest-quality base stocks and created an additive package specifically designed for the unique requirements of motorcycle and ATV engines. Constant testing and development give today's GN4 even better shear resistance, viscosity stability and cleanliness to meet the requirements and stresses of a new era of engine technology.
