Abstract: Lubricants is mostly used to reduce the friction and wear from the sliding and metal contact surfaces, because of which can smoothly moves in each other. Nowadays, it is important issue to protect the environment and replace the mineral oil due to the increase of the oil prices and reduction of the oil reserves. It is essential to find out an alternative oil for the replacement of mineral oil based lubricants and vegetable oil already meets the requirements. Vegetable oils based biolubricants are non-toxic, biodegradable, renewable and have a good lubricating performance than mineral oil based lubricant. This study evaluated the lubricating properties and tribological characteristics of Moringa oleifera oil and compared with coconut, rice brain and lube oil. The friction and wear characteristics of the oil investigated by using a four ball tester according to ASTM 4172 method. MOO showed higher viscosity and viscosity index compared to other vegetable oils and it is better for boundary lubrication. In thermogravimetric analysis, it was found that MOO remains thermally stable up to 300°C. MOO showed a lower amount of coefficient of friction and wear scar diameter compared to other vegetables oils and lube oil. Therefore, Moringa oleifera oil is very potential to use as a lubricating oil in industrial applications due to better lubricating performance.
