In this article, we focus on parameters oil marketers need to con- sider when selecting both the appropri- ate engine oil performance level and the additive chemistry for formulating their motorcycle oils, to ensure their brand re- mains relevant to the market.

To improve combustion efficiency, one significant hardware change being intro- duced by motorcycle original equipment manufacturers (OEMs) has been the move from carburetor to port fuel injec- tion technology. Coupled with increasing engine power densities, the performance requirements of motorcycle oils mean they must operate in more severe con- ditions, resulting in the need for robust piston cleanliness performance as well as improved oxidative and thermal stability. Issues of deposit formation can be ad- dressed with enhanced detergency con-
