Viscosity Index Improvers Market: USD 5.76 Billion by 2032, Growing at 3.29% CAGR

Market Overview

The Viscosity Index Improvers Market was valued at USD 4.59 billion in 2025 and is expected to reach nearly USD 5.76 billion by 2032, growing at a CAGR of 3.29% during the 2026–2032 forecast period. Rising demand for high-performance automotive and industrial lubricants is supporting the adoption of polymer additives capable of maintaining stable oil viscosity across wide operating-temperature ranges.

Viscosity index improvers are complex polymer additives that reduce the degree to which a lubricant’s viscosity changes when temperature rises or falls. Their molecular chains expand at higher temperatures and compensate for lubricant thinning, allowing oils to preserve protective films around engines, transmissions, hydraulic equipment and industrial machinery. This makes them essential to multigrade oils and eliminates the need for different seasonal lubricant formulations.

The market covers polymethacrylate, olefin copolymer, polyisobutylene, styrene-butadiene copolymer and emerging polymer blends. These products are used in automotive lubricants, industrial oils, hydraulic fluids, and marine and aviation lubricants across automotive, machinery, aerospace, oil and gas, and other end-user industries.

The market matters because modern equipment operates under increasingly demanding thermal and mechanical conditions. Smaller engines, higher operating temperatures, longer lubricant-drain intervals and greater pressure to improve fuel efficiency require oils that remain effective during cold starts, sustained high-speed operation and heavy-load industrial use.

Key Growth Drivers Fueling the Viscosity Index Improvers Market

Rising Automotive Production and Vehicle Ownership: The automotive industry is the largest consumer of lubricants and remains the central demand driver for viscosity index improvers. Engine temperatures change substantially during operation, making viscosity control important for limiting friction, reducing wear, cooling pistons and protecting engine components from combustion-related contaminants.

Growth in passenger and commercial vehicle ownership, particularly across Asia Pacific, is increasing demand for engine oils, transmission fluids and driveline lubricants. Higher lubricant consumption directly supports the use of viscosity-modifying polymer additives.

Demand for Fuel-Efficient Multigrade Oils: Vehicle manufacturers and lubricant formulators are developing lower-viscosity oils that reduce energy losses while maintaining adequate protection at high temperatures. Viscosity index improvers allow these formulations to remain sufficiently fluid during cold starts while preventing excessive thinning during normal engine operation.

The ability to produce multigrade lubricants is commercially important because it reduces the need for seasonal oil replacement. OCP, PMA and other polymers enable lubricant suppliers to balance fuel economy, wear protection, shear stability and temperature performance.

Expansion of Industrial Machinery: Industrial development across manufacturing, mining, power, construction and process industries is increasing lubricant demand. Machinery exposed to changing loads and temperatures requires oils that maintain reliable viscosity to reduce friction, equipment wear and unplanned downtime.

Growth in emerging economies creates additional opportunities for hydraulic fluids, compressor oils, gear oils and other industrial formulations. Investment in industrial capacity across BRICS economies is expected to support the wider lubricant-additives value chain.

Stricter Performance and Emission Requirements: Fuel-economy expectations and environmental regulations are pushing lubricant manufacturers toward advanced additive packages. High-quality viscosity modifiers help reduce mechanical losses and support lower-viscosity formulations without sacrificing engine protection.

Regulations are also influencing polymer selection, chemical registration and product development. European REACH requirements place particular emphasis on environmental and human-health protection, encouraging suppliers to invest in compliant, efficient and technically advanced additive technologies.

Growth in Synthetic and Premium Lubricants: Synthetic oils are increasingly used in high-performance automotive, aerospace and industrial applications. These formulations require additives with strong shear stability, oxidation resistance, low-temperature performance and compatibility with different base stocks.

Polymethacrylate products benefit from premium synthetic-oil demand because they provide strong low-temperature behaviour and oxidation stability. Olefin copolymers remain widely used where manufacturers prioritize cost efficiency, broad compatibility and effective high-temperature viscosity control.

The market faces pressure from fluctuating crude-oil and base-oil prices. Raw-material volatility creates uncertainty for lubricant-additive manufacturers, affecting procurement decisions, production costs and operating margins.

Longer oil-drain intervals also limit lubricant consumption. MMR notes that improvements in lubricant and engine technology have extended some drain intervals from 25,000 miles to 50,000 miles, potentially reducing replacement frequency and viscosity-index-improver demand.

AI and Digital Transformation Impact on the Viscosity Index Improvers Market

AI is changing the Viscosity Index Improvers Market by accelerating lubricant formulation and reducing laboratory trial-and-error. Digital formulation platforms can compare base oils, target viscosity, shear stability and thickening efficiency before physical testing begins. This helps research teams screen polymer combinations faster and focus laboratory resources on the most promising formulations.

BASF’s Thickener Explorer demonstrates this shift by allowing users to model viscometric properties and explore product recommendations through a digital interface. Evonik also provides calculation tools for viscosity index, blending efficiency, base-oil mixtures and lubricant formulation.

Machine-learning models can expand this approach by analysing historical test data, polymer structure, additive interaction and application requirements. Formulators may use predictive tools to identify combinations that balance viscosity improvement, oxidation resistance, shear stability, fuel economy and cost.

Digital technologies also support manufacturing consistency and quality control. Automated process monitoring can track polymerization conditions, raw-material variation and product performance, helping additive producers maintain tighter specifications across production batches.

AI will not replace physical validation because lubricant additives must perform under demanding engine and machinery conditions. Its main impact will be faster candidate selection, more efficient formulation development and improved alignment between additive chemistry and specific equipment requirements.
