QUALITY ASSESSMENT OF LUBRICANTS SOLD IN BENIN CITY

ABSTRACT

This project conducted a comprehensive quality assessment of both branded and unbranded lubricants, encompassing oils and greases. The evaluation focused on key parameters, including viscosity, acid number, and the presence of metal contaminants, with the objective of providing valuable insights into the performance and suitability of these lubricants for various applications. Viscosity Analysis revealed substantial differences in viscosity between the branded and unbranded lubricants. Both at 100°C and 40°C, the branded oil exhibited superior viscosity properties compared to the unbranded counterpart. Similarly, the branded grease outperformed the unbranded variant in terms of viscosity. Acid Number Assessment indicated that branded lubricants possessed a significantly lower acid number (2.09 mg KOH/g) in contrast to unbranded lubricants (3.7 mg KOH/g). This discrepancy implies that branded lubricants are more resistant to oxidation and have the potential for longer oil life. In Metal Contaminants Examination both branded and unbranded lubricants displayed low levels of metal contaminants, including iron, copper, and lead. These levels were well within acceptable limits, alleviating concerns related to heightened engine wear or damage. Furthermore, the branded lubricants showed a superior ability to control metal contaminants compared to their unbranded counterparts. In summary, the findings underscored the considerable performance differences between branded and unbranded lubricants. Branded lubricants exhibited favorable viscosity characteristics, lower acid numbers, and better control of metal contaminants. These results provide compelling evidence for the potential advantages of using branded lubricants over unbranded alternatives, highlighting the importance of informed product choices to ensure machinery longevity and efficient performance in lubrication applications.
