Investigation of Engine Lubrication Using Altered Coconut Oil

Coconut oil, a renewable and biodegradable substance, was chemically modified to evaluate its viability as lubricant base oil. This paper investigates the physicochemical, tribological, and thermal properties of altered coconut oil in comparison with standard SAE 40 engine oil. Using standard test methods (ASTM D445, D97, D92, D4172), properties such as viscosity, pour point, flash point, and wear resistance were evaluated and its shows improved viscosity index, lower pour point, and comparable anti-wear characteristics, making altered coconut oil a potential eco-friendly lubricant for internal combustion engines. The results indicate that altered coconut oil demonstrates improved thermal and tribological properties and offers a viable biodegradable alternative to conventional lubricants.
