Abstract

Lubricant inside an engine is important as a substance to be used in order to reduce friction, heat and wear between two contact surfaces. Due to the environmental friendly awareness lately, vegetable oil has become a primary choice as base oils for lubricant applications. Vegetable oil has favoured position on its properties such as high viscosity index, high solvency, excellent biodegradability and low toxicity. The purpose of this study is to determine the possibility composition of virgin coconut oil blend with engine oil. In this report, virgin coconut oil was blended with engine oil and its lubricating properties were investigated. The percentage of mixture composition between VCO and engine oil are at 10%, 20%, 30%, 40% and 50% of VCO. Besides that, pure oil of 100% VCO and 100% engine oil was also investigated on its physical properties to be compared together. The tests were conducted on its properties of coefficient of friction by using four ball testing machine with accordance of ASTM D4172, the wear scar diameter from the steel ball observed by using Scanning Electron Microscope on its wear performance and kinematic viscosity by using viscometer. The results showed that, by mixing 50% VCO, it improves on the coefficient of friction and wear performance. However, at composition 10% VCO, it shows the smallest wear scar diameter and highest value at kinematic viscosity between the mixtures. In conclusion, by mixing VCO with engine oil, it produces better performance compared with the pure engine oil or pure virgin coconut oil itself.
