Global Lubricant Viscosity Index Improvers Market Strategic Research Report

Scope of the Report

The global Lubricant Viscosity Index Improvers market size is predicted to grow from US$ 3,180 million in 2025 to US$ 4,121 million in 2032; it is expected to grow at a CAGR of 3.8% from 2026 to 2032.

Viscosity Index Improvers (VIIs), also known as Viscosity Modifiers, comprise a class of additives that improve the viscosity-temperature characteristics of the lubricant, making the oil's viscosity more stable as its temperature changes. Lubricant Viscosity Index Improvers is made from polymers, which are long and flexible molecules used in the production of lubricant to reduce lubricant viscosity changes at high and low temperatures. When viscosity index improvers are added to low-viscosity oils, they effectively thicken the oil as temperature increases. This means the lubricating effect of mineral oils can be extended across a wider temperature range.

The whole lubricant viscosity index improvers market is mainly dominated by several suppliers, like Lubrizol, Chevron Oronite, Infineum, Afton Chemical. These manufacturers have mature technology and strong supply chain management, making them owning a certain market share globally.

lubricant viscosity index improvers improve the viscosity-temperature characteristics of the lubricant, making the oil's viscosity more stable as its temperature changes. key market drivers of lubricant viscosity index improvers as follows:
