The wide use of petroleum-based lubricants increases concerns with regard to pollution, and the rising of awareness of greenhouse gases has produced a demand for the use of environmentally friendly and biodegradable lubricants for industrial applications. Vegetable oils are one of the bio-oils that is a good choice for the replacement for petroleum products, due to their environmentally friendly characteristics. Many researchers have accomplished bio lubricants from sunflower oil, corn oil, palm oil and soy oil but few have studied Jatropha, neem and pongamia oil, as a lubricant. In this study, Variation of the coefficient of friction with sliding distance for bio lubricants with Jatropha, neem and pongamia as base oils were studied. Experiments were conducted using a pin on disc tribotester. The results were compared with those of 20W50 mineral oil.
