Abstract

This review paper focuses on the potential of bio-lubricants, derived primarily from vegetable oils such as soybean, palm, and cottonseed oils, as sustainable alternatives to conventional petroleum-based lubricants for automotive engines. It highlights their environmental benefits, including biodegradability and reduced toxicity, alongside comparable or improved tribological performance when enhanced with additives and chemical modifications like transesterification. The paper discusses the influence of fatty acid composition and physicochemical properties on lubrication efficacy, the use of advanced modeling techniques for formulation optimization, and the challenges bio-lubricants face, such as oxidative stability, cold flow limitations, and higher production costs. Future research directions emphasize improving performance consistency, cost-effectiveness, and the integration of novel additives to support broader industrial adoption.
