Abstract

The main objective of this research is to examine how low-cost commercial friction and wear engine oil performance towards branded engine oils. In this research also the viscosity of motor oil was studied. Engine oil lubricates an internal combustion engine component and protects it against corrosion and keeps it cool while in operation. To determine the friction coefficient, four ball tests were conducted. After that, the diameters of wear scars on the balls were determined using the inverted microscope. The American Society for Testing and Materials (ASTM) 04172 was the basis for all standards in this technique. ASTM 04172 is the standard wear preventive method for lubricating fluid (Four-Ball Method). Viscosity heated was employed for viscosity determination of the oil. For the commercial engine oil, KUMO SAE 5W40 and 10W40 is selected. While the branded engine oil is Shell Helix HX8 and Shell Helix HX7. Finally, the results indicate whether commercial engine oil is suitable for usage or not.
