Evaluation of Additive Effects on Lubricating Oil Properties in Automobile Engines
Abstract: Lubricating oils play a critical role in reducing friction, controlling wear, and enhancing the operational efficiency and service life of automobile engines. The performance of these oils is strongly dependent on the quality of base oils and the type and concentration of additives incorporated during formulation. This study evaluates the impact of additives on the physicochemical characteristics and degradation behavior of lubricating oils under automobile engine operating conditions. Two commercially …
