Global Viscosity Index Improvers Market size was valued at USD 160.5 million in 2024 and is poised to grow from USD 171.57 million in 2025 to USD 292.6 million by 2033, growing at a CAGR of 6.9% during the forecast period (2026-2033).
Growth in the market is driven by increasing demand for high-performance lubricants, increasing production of automobiles, and a growing focus of almost all industries on fuel efficiency and durability of engines. Growing concerns regarding a reduction in carbon footprints and enhancement of thermal stability of lubricants are accelerating the demand for premium viscosity index improvers.
The increasing electric vehicle demand is also influencing manufacturers to produce specifically designed VI improvers for EV transmission fluids and thermal management fluids. The automotive industry remained the largest consumer of viscosity index improvers in 2024 due to strict emission standards and the trend of moving toward synthetic and semi-synthetic engine oils, requiring advanced polymer additives that keep viscosity stable over temperature fluctuations.
The Asia-Pacific region accounted for the maximum share in 2024 on the back of expanding automotive manufacturing bases, rapid industrialization, and increasing consumption of lubricants in China, India, Japan, and South Korea. North America and Europe continued to register steady growth, modernization of industrial machinery, advanced lubricant formulation technologies, and further investments in high-performance engine oils. Raw material volatility, issues with polymer degradation, and continuous R&D have put pressure on the growth of the market, though it keeps expanding. Strategic collaborations between additive manufacturers, polymer scientists, and lubricant formulators are expected to unlock new opportunities and support long-term competitiveness in the global viscosity index improvers market.
How is Artificial Intelligence Enhancing Viscosity Index Improvers Market?
Artificial Intelligence is significantly transforming global viscosity index improvers market strategies by elevating these platforms from simple controllers to intelligent, self-optimizing manufacturing hubs. AI is becoming increasingly common in polymer design processes that involve machine learning algorithms to analyze molecular structures, viscosity-temperature behaviors, shear stability, and lubricant interaction patterns for the development of more effective and durable VI improvers. This speeds up the formulation development process by reducing the need for comprehensive physical testing. Key applications of AI in 2024 were in predictive polymer formulation, where AI-driven material models empowered manufacturers to design VI improvers with improved shear resistance and thermal stability.
AI thus holds a very central place in predictive maintenance across the VI improver production plants by detecting abnormalities-also with the help of real-time data from reactors, mixers, and polymerization units-to prevent equipment failure before it occurs. In addition, AI-enabled quality inspection systems are increasingly being integrated with manufacturing lines to monitor polymer uniformity, detect impurities, and optimize parameters in real time for maintaining consistent product quality.
A leading additive producer implemented an AI-enabled process optimization system that reduced polymer degradation rates and enhanced production efficiency in 2024. AI is further remodeling the supply chain in ways such as enhancing demand forecasting, allowing for accurate raw material planning, and optimizing global distribution on behalf of lubricant manufacturers. These AI-driven capabilities make viscosity index improvers more reliable, high-performance components of next-generation lubricant technologies, enabling smart manufacturing, faster innovation, and data-driven decision-making across the global market.
