Viscosity Index Improvers (VIIs) are additives used in lubricating oils to improve their viscosity-temperature properties. An oil's viscosity is an important feature determining its capacity to lubricate and protect machinery at various operating temperatures. VIIs are used to reduce the change in viscosity with temperature changes, ensuring optimal lubrication under various situations.

Lubricants reduce wear and tear, extending the life of machines. As a result, demand for lubricants increases, driving demand for the viscosity Index Improvers Market. Automobiles need braking fluids, transmission lubricants, engine lubricants, and so on, which must be replenished regularly to guarantee proper operation and longevity. As a result, the demand for high-quality lubricants that function at varied temperatures is increasing, complementing the demand for VI improvers and driving market expansion.


  • Olefin Copolymer accounts for the largest share of the market by type
  • Manufacturing generates the highest revenue share in the market based on end-users.

Market Dynamics

Market Drivers:

Automotive Industry Growth

The rising automotive industry is a key driver of the viscosity index improvers market. As worldwide vehicle production rises, so does the demand for high-quality lubricants, notably those with effective viscosity index improvers, to satisfy the needs of modern engines. Global light vehicle production in 2023 is predicted to reach 89.8 million units, a 9.0% increase over 2022 levels that exceed projections in several countries, adding to suggested inventory restocking. Modern engines are engineered to function in various situations, including harsh temperatures and high-performance surroundings. Engine oils in modern automobiles frequently incorporate viscosity index improvers to ensure constant lubrication over a wide temperature range. For example, multigrade oils such as 5W-30 or 10W-40 use VIIs to maintain proper viscosity at low and high temperatures, improving engine protection.

Furthermore, the growing production of electric cars (EVs) contributes to this trend. While EVs require less lubrication than regular internal combustion engine vehicles, specialty lubricants containing VIIs remain critical for components like bearings and gears in electric drivetrains. Global electric vehicle (EV) sales are predicted to increase to 16.7 million in 2024 from 14 million in 2023. Canalys research projects that global EV sales will reach 13.7 million in 2024, representing a 29% growth. As the automotive industry evolves, focusing on fuel efficiency, emission reduction, and advanced powertrain development, the demand for lubricants containing efficient viscosity index improvers is projected to persist and rise. The above factors represent an influential Viscosity Index Improvers Market trend.

Market Restraints:

Fluctuating Crude Oil Prices

The pricing and availability of base oils obtained from crude oil significantly impact the market for viscosity index improvers. Changes in crude oil prices can substantially impact the cost dynamics of producing viscosity index improvers. According to the American Petroleum Institute (API), base oil expenses can make up a major component of the overall lubricant cost structure. Crude oil price variations directly impact the cost of producing base oils, influencing the costs of manufacturing lubricants, especially those with viscosity index improvers. According to the US Energy Information Administration (EIA), Brent crude oil prices will average USD 84 per barrel in the first half of 2024. This decreased from an average of USD 78 per barrel in December 2023, partly attributed to OPEC+ production curbs. The EIA expects crude oil prices to rise slightly in the first quarter of 2024, from USD 78 per barrel in December 2023 to USD 85 in March 2024. 

Hence, Volatile crude oil prices pose issues for both lubricant makers and end users. The cost of base oils, a key component in viscosity index improver formulations, can fluctuate rapidly and unexpectedly, affecting overall production costs and pricing strategies in the viscosity index improvers market. Furthermore, the global economic climate and geopolitical variables influence crude oil price volatility. Economic downturns and geopolitical tensions can cause quick fluctuations in oil prices, affecting the whole lubricants business, including the viscosity index improvers market.

Market Opportunity:

Focus on Sustainability and Bio-Based Additives

Growing environmental consciousness and sustainability standards create an opportunity to develop and implement bio-based viscosity index improvers. To support eco-friendly initiatives, manufacturers can look into sustainable alternatives created from renewable sources. Bio-based additives from vegetable oils, esters, and other renewable feedstocks can increase the viscosity index. These additives provide lubricant formulators with a long-term option for improving the viscosity-temperature performance of lubricants. For example, ester-based lubricants are non-toxic, renewable, and generate no greenhouse gases. They can be employed as viscosity index promoters, antioxidants, detergents, emulsion stabilizers, and pour point reduction additives. This increase is due to the growing demand for environmentally friendly and biodegradable lubricants. Furthermore, more efficient, sustainable automobiles will increase lubricant production and consumption. 

Furthermore, several regulatory initiatives and certifications encourage using bio-based lubricants and additives, creating a favorable environment for implementing bio-based viscosity index improvers. In 2023, the European Union (EU) updated the Renewable Energy Directive (RED) known as RED III. RED III intends to increase the proportion of renewable energy in the EU's total energy consumption to 42.5% by 2030, with an indicative target of 2.5%. This is nearly twice the existing percentage of renewable energy in the EU. In June 2023, the Commission announced new rules governing the proportion of biofuels and biogas in mixed fuels. These blended fuels can be used to meet the Renewable Energy Directive's requirement for renewables in transportation.
