About 45% of the registered motorcycles are run on two-stroke engine that emits “white smoke” to cause serious air pollution problem. In this paper, information on the physical and chemical properties of ten motor oils on domestic market for two-stroke engines and the emission from 10 two-stoke motorcycles was collected. Using the SPSS statistical software, the collected data were analyzed to study correlations among the motor oil physical and chemical properties, suspended pollutants (smoke), carbon monoxide (CO), hydrcocarbons (HC), and nitrogen oxides (NOx). The results show that higher particulate pollutant (smoke) corresponds to lower CO and HC+NO emitted from moving motorcycles, and that the smoke is not related to the emission of CO and HC from idling motorcycles with P-value greater than 0.01. Further, the motor oil is not correlated to emission of CO and HC+NO from moving motorcycles, and emission of CO and HC from idling motorcycles with both P values greater than 0.01. The emission of CO and HC from idling motorcycles shows obvious differences with respect to types of motorcycles (P-values <0.01). Types of motor oil have some influence on the particle pollutants emitted from motorcycles but the motor oil physical and chemical characteristics are not correlated to the emission of particle pollutants (P-value >0.01).
