Summary:

As well as a four-wheeled vehicle, in the field of motorcycle,development of the CO₂ reduction technology and practical use arerequired for global environment protection. Therefore the energyconserving by engine oil is required. There are severaltechnologies which have been applied to the passenger car engineoils using lower viscosity base oils and some friction modifieradditives.However, these technologies might bring difficulties or problemsto apply to the motorcycle engine oils. Since motorcycles normallyhave transmission gears and a wet clutch system inside thecrankcase, the gear lubricity and clutch friction performance areadditionally required for motorcycle engine oils.Motorcycle engine oils are also used under severer conditionsthan passenger car engine oils. Therefore, lower volatilityperformance at higher temperature conditions, higher shearstability, anti-wear performance and gear pitting toughness areneeded.In this study, we report the results of motorcycle engine oilperformance evaluation with engine oils containing high qualitymineral base oils and specially selected polymers. The high qualitybase oil contributed to reduce oil consumption, compared with thecurrent 10W-30 grade motorcycle engine oil. The moderate selectionof polymers can increase oil film thickness and also improve shearstability. Additionally, actual motorcycle engine test wasconducted. The candidate oil showed better fuel saving and bettereffect for gear fatigue and noise prevention
