Abstract

Petroleum based lubricant is a non biodegradable and due to its complex disposal making it non-environmemtal friendly. Thus, this study will be higlighted on developing a new bio lubricating grease as an alternative to subrtitute the mineral based oil in the lubricatimg grease. In this study, four samples of lubricating grease were prepared with different concentration thickener. The bio-lubricating grease were developed by using a fresh commercialized cooking palm oil with addition of ZDDC as additive and Lithium Hydroxystearate as thickener. The samples were tested and characterizedd in accordance to ASTM test methods to determine the coefficient of friction, wear scar diameter, and extreme pressure. The COF and EP were characterized using four ball test method while WSD was observed under SEM. The result from test and characterization of the newly developed bio-lubricating grease showed palm with 2 wt% of ZDDP and 10wt% of Lithium Hydroxystearate exhibit the desirable result from the other samples which give the lowest coefficient of friction at 0.090 and the wear scar diameter of 765.3 μm. The highes load resist under extreme pressure test also was observed at 315 kgf. As As a conclusion, the positive performance of this newly developed bio-lubricating grease resulted in producing an alternative lubricant which can be suggested to be applied to industry today as substitution of using mineral based oil lubricant
