Viscosity indices were calculated from the measured viscosity at 40℃ and 100℃ using ASTM D (American Society for Testing and Materials ) 2270 and method graphically using ASTM D 341. The viscosity-temperature coefficients for vegetable oils were calculated from the measured viscosity at 40℃ and 100℃.展开更多
