Experimental evaluation on the tribological properties
In the present study, analysis of coconut oil as a lubricant has been carried out in the perspective of its tribological behaviour using a pin-on-disc tribometer. Copper oxide nanoparticles are added to the oil on weight-percentage basis, the variation of its friction-reduction and antiwear properties are analysed.

Enhancement of cold flow property of coconut oil by alkali
The low cold flow property of the coconut oil restricts its tribological applications as a lubricant. The flow property at low temperature was improved by removing the glycerol molecules from the oil thereby converting the fatty acids into esters by the process of alkali esterification.

Experimental evaluation on the tribological properties
Experimental evaluation on the tribological properties of coconut oil by the addition of CuO nanoparticles. Wear scar obtained in the presence of nano oil is smoother compared to that with bare coconut oil. When the level of nanoparticles increases above the optimum level, friction coefficient and wear rate are seen to increase.

Experimental studies on viscosity and tribological
Coconut oil (CO) when used as a lubricant at metallic interfaces exhibits a low coefficient of friction but high wear rate compared to mineral oils, which limits its application as a commercial lubricant, whereas mustard oil (MO) exhibits better wear resistance.

Evaluation of the tribological and thermo-physical
Coconut oil finds mention as a lubricant among the other widely used vegetable oils like rapeseed oil and olive oil during the pre-mineral oil era, though it had not been widely used as a lubricant because of the high congelation temperature . Coconut oil belongs to a unique group of vegetable oils called lauric oils.
