Sustainability has evolved from being just a niche engagement to a fundamental necessity. The reduction of carbon emissions from aspects of human activity has become desirable for its ability to mitigate the impact of climate change. The Transportation industry is a critical part of the global economy – any effort to curb emissions will have a significant impact on CO2 reduction. Engine lubricant can play an efficient and key role to enhance powertrain performance that have undergone significant hardware changes to reduce emissions.As part of a significant collaborative programme between Tata Motors and Infineum, a new engine oil formulation SAE 5W-30 API FA-4 has been developed and commercially introduced for use in the modern Bharat Stage 6 Phase 2 engines. Introduction of SAE 5W-30 API FA-4 engine oil for Tata Commercial Vehicle application is a step towards delivering a sustainable option beyond improved fuel economy, longer drain interval and enhanced engine wear protection, resulting in reduced carbon footprint of Tata commercial entire fleet. This is the first such comprehensive step towards sustainability in India that sets the trend for a strong quality upgrade in engine oils for commercial vehicles.Development of lubricants towards this must address many challenges of today’s world. Modern Commercial Vehicle engines operate at higher temperatures than before, promoting both oxidation and nitration of the lubricant. At the same time, higher levels of fuel economy require usage of lower viscosity engine oils, which must then be formulated in a manner that protects the engine and maintains hardware durability despite the presence of a thinner lubricant. Theoretical analysis depicting Minimum Oil Film Thickness using simulation software confirmed oil’s capability to provide adequate hardware protection. The formulation uses innovative additive and viscosity modifier technologies together, with base oil systems that enable higher levels of engine fuel economy without compromising durability. The new formulation has been tested extensively both on engine dynos and through field trials in India under varied conditions.
