Mineraloils have long been utilizedin industriesas machining lubricants, which contributed to theirdepletion and hick in priceandbeing non-biodegradable, harmful to the environment,and risk to health.Plant-basedoil is more biodegradable, renewable, and environmentally friendlyas a green alternative.However, in their crudestate, plant-based oilsare not up to par with the standard mineral oil used in lubricationin terms of high acidity, low-temperatureperformance,and oxidative instability.Further

The result of viscosity index revealsthat MTOP+PIL1% had the highest value of 178.76. MTO+AIL10% exhibits the lowest average COF(0.061) compared to other MTOs lubricants. Among MTOP, MTOP+PIL1%also had the lowest average COF which is 0.082. The addition of PIL1% to MTO and MTOP lowered the average scar diameter, 730.77μm and 674.93μmrespectively. With the enhanced properties from chemical modification and additives, Tamanu oil can be proposed as a green alternative fordevelopingthe metalworking fluid industries in the future.
