In this work, density ρ and dynamic viscosity η of the binary mixtures of methyl esters (1) + ethyl esters (2) and ternary blends of methyl esters (1) + ethyl esters (2) + diesel fuel (3) were measured at various compositions and temperatures. The methyl and ethyl esters were produced through transesterification of palm and jatropha oils. The binary and ternary blends demonstrate temperature-dependent behaviors, and viscosities and densities of decreased nonlinearly and linearly with temperature, respectively. The results indicated that the increase in methyl ester contents increased the densities of the binary and ternary blends. The results also indicated that the blends of jatropha esters have higher densities and viscosities in comparison with those obtained from palm oil. In addition, with the decrease in the diesel fuel content the blends viscosities and densities increased due to the higher viscosities and densities of methyl and ethyl esters.
