Degradation of Lubricating Oils Characteristics upon Utilization by Automobile Engine

Chukwuemeke. P Ukpaka, Obed Chucks Ekeocha

Abstract


Investigation was conducted to examine the functional parameters, which demonstrates the degradation of lubricating oils characteristics upon utilization by automobile engine. The functional parameters studied in this research work are density, pour point, flash point, kinematic viscosity at 40 and 100 , pH value, refractive index, viscosity index, water content concentration, TBN, Sediment concentration, sulphate concentration and TAN concentration. The results obtained from the investigation demonstrates the significant variation on the concentration of functional parameters when compared with the unused and used ones upon the influence of distance covered by the automobile engine. The characteristics of the properties revealed that the behavior of lubricating oil is controlled by the type of additives used during the production in terms of quality and reliability upon the influence of temperature and distance covered. The lubricating oils investigated for this research work were Tecno oil 20W/50 and Mobil 20W/50 multigrade engine oils.

Key words: Degradation, lubricating Oils, characteristics, utilization, automobile engine
