Microstructure and Wear Behaviour of Engine Oil Treatment Added Bio-Lubricant

As engine cylinder liner piston ring tribotester was used to investigate the tribological effect and thermo-physical properties of engine oil treatment added with waste palm oil blended with SAE40. The designs utilize rotational speeds (200 RPM to 300 RPM), volume compositions and applied loads (2kg to 9kg). Detailed wear scar analyses of the specimen from the tribology tester have also been carried out using FESEM. It was discovered that 5% addition of waste oil added with engine oil treatment and base lubricant can be used as lubricating oil without any shortcoming, which would help to reduce the global demand of petroleum based lubricant.
