Fossil fuels are being gradually exhausted and need to go to new energy options. The vegetable oils are significant resources for biodiesel production and the best alternative for diesel from crude oil. This research aims to study the physical characteristics of diesel in combination with linseed oil, waste cooking oil and rubber seed oil as ternary blend biodiesels. Ternary blends mean a combination of diesel, biodiesel-1 and biodiesel-2. Four ternary blends have been prepared in various proportions from linseed and rubber seed oil, and another four ternary blends have been prepared from linseed and waste cooking oil. These three oils have relatively similar physical characteristics, non-edible. Physical characteristics tests were carried out using ternary biodiesel mixtures. The experimental study has shown the physical characteristics of the ternary blend by comparing the blends' kinematic viscosity, density, flash point and fire point. The blend of 95% diesel, 2.5% linseed and 2.5% rubber seed biodiesel gives better physical characteristics. By analysing the graph, the particular blends give similar physical characteristics to diesel. So the blend of linseed and rubber seed oil gives the best physical characteristics compared to other blends. It has lower viscosity values, nearly the same as diesel. So it does not affect the performance of an engine.
