Summary:

The focus on sustainability has encouraged innovation across industries with a growing emphasis on minimizing environmental impact. In the transportation sector, optimizing engine lubricants emerges as a crucial avenue for achieving sustainable performance as used engine oil is the primary lubricants waste stream. Re-Refined Base Oil (RRBO) presents a compelling solution, offering a sustainable alternative to virgin base oils. By reclaiming and reprocessing used oil, RRBO not only minimizes waste but also embodies the ideology of circularity, promoting resource efficiency and environmental conservation.This study presents the collaborative efforts between an Indian Automotive OEM and Lubricant Technology Partner towards the development of engine oil utilizing Re-Refined Base Oil (RRBO) for automotive applications. Specifically, two formulations were targeted: a 5W-30 A5/B5 oil for Bharat Stage IV passenger car usage and a 15W-40 CI4+ oil for Bharat Stage IV commercial vehicle application, both incorporating 10% RRBO.Extensive testing was conducted to assess the physicochemical properties of the base oil and the finished oils containing RRBO. Bench tests were employed to identify performance of key parameters, including oxidation resistance, deposit formation, and corrosion susceptibility. Engine test bed and vehicle field testing were performed to evaluate the real-world performance of finished oils with RRBO. The results demonstrate that 10% RRBO-based formulations exhibit performance levels comparable to those formulated with virgin base oil, affirming the viability and efficacy of RRBO as a sustainable alternative.In conclusion, this study highlights the integral role of RRBO in advancing circular economy principles within the automotive industry without sacrificing performance. By embracing resource efficiency and waste reduction, RRBO contributes to a more sustainable and resilient lubrication ecosystem, paving the way for a greener and more responsible future
