In a market survey conducted in 2010 on major South East Asian cities, motorcycle users identified some of the most valued oil features being clutch friction, durability and engine cleanliness. In the fast growing motorcycle markets of Asia where motorcycles are used mainly for daily transportation needs, there are enormous opportunities for motorcycle oils delivering differentiated attributes that provide superior reliability to the end users. It was with this market perspective that this new additive technology was developed. The additive technology was developed based on a unique set of components and formulation approach to meet the lubrication challenges of motorcycles, particularly its high shear and temperature conditions. In a forward-looking standpoint, the development was aligned to the current energy conservation and environmental trends in the personal mobility oil segment.

The global use of biodiesel fuel blends derived from fatty acid methyl esters (FAME) is increasing; driven by legislation derived from political, economic and environmental factors. The presence of FAME biodiesel changes the operating environment of the engine and after treatment devices, affecting the performance characteristics and requirements of the lubricant. As part of a wider research project into the impact of biologically-sourced fuels on crankcase lubricant performance, this paper documents the impact of biodiesel on corrosion-related performance. The effect of FAME biodiesel on lubricant corrosion control and the differences in performance due to FAME source are described. Mechanistic studies into the corrosive nature of FAME are reported. Novel lubricant technologies tailored to control the negative impact of FAME in the crankcase are demonstrated.
