There is a global demand for bio-based lubricants which are biodegradable, non-toxic and environmental friendly. In this study, various bio-lubricants formulated from Jatropha oil were investigated for their friction and wear characteristics at 3.8 m/s velocity and different loads (50, 100 and 150 N) using a pin on disc tribometer. SAE 20W40 was used as the conventional lubricant and blended in the ratio of 15, 30 and 50% by volume. As a function of sliding distance and on the application of different loads, JB15 contributes towards better results among the various blends of Jatropha oil. The addition of JB15 to the conventional lubricant resulted in a better lubricant in terms of reducing friction and worn surfaces on the top surface of the pin at various loads. JB15 can act as an alternative lubricant to increase mechanical efficiency and contributes to a reduction in dependence on petroleum based products.
