The engine oil market size was valued at US$ 81.56 billion in 2024 and is expected to reach US$ 114.81 billion by 2031; it is estimated to register a CAGR of 5.2% from 2025 to 2031.

The engine oil market growth is driven by an increasing vehicle population, developing industrial and construction sectors, and the need for high-performance synthetic and semi-synthetic lubricants with better engine protection, fuel efficiency, and a longer drain interval. These sophisticated formulations are essential in contemporary engines, particularly turbocharged, direct-injection, and hybrid engines, where high temperatures, pressure, and close tolerances render traditional mineral oils ineffective. Additionally, using traditional oils in such engines can result in increased wear, sludge formation, and lower efficiency. Demand is rising as stricter emissions standards (Euro 7, EPA, China VI), growing electric and hybrid sales requiring specialized thermal fluids, and strong lubricant exports from India, China, and Southeast Asia reshape the market. With cost of ownership, engine longevity, and compliance with OEM standards becoming priorities for fleets and consumers, high-quality engine oils are now a critical component in an increasingly regulated automotive and industrial landscape.

The engine oil market trends are influenced by ultra-low-viscosity grades (0W-8, 0W-16, 0W-20), pervasive change to synthetic and high-performance Group III+ / PAO base stocks, and the fast growth of specific EV/hybrid thermal-management fluids. Stringent emission regulations (Euro 7, China VI-b, EPA 2030), and the OEM fuel-economy requirements are compelling formulators to low-SAPS, friction-modified oils that reduce carbon dioxide by 1-3 percent and maintain engine life in downsize, turbocharged motors. Recent improvements in hydrocracking and GTL technology provide close PAO performance with lower cost, allowing a 1525 percent reduction in the use of costly base oil and treat rates. At the same time, bio-based and re-refined base stocks containing up to 50 per cent of recycled content are becoming popular as a fleet operator, and OEMs pursue Scope 3 and ESG goals.

The Asia Pacific region is expected to register the fastest CAGR in the global engine oil market from 2025 to 2031, driven by rapid expansion in the automotive, industrial, and transportation sectors across emerging economies. Rising vehicle ownership, growing commercial fleets, and increasing production of passenger cars and two-wheelers are significantly boosting the demand for high-performance engine oils. Strengthening economic activity, urbanization, and expanding logistics networks across China, India, Southeast Asia, and Australia further support market growth. Additionally, leading lubricant manufacturers are investing in localized production facilities, advanced formulation technologies, and distribution network enhancements to meet rising regional demand. Increasing consumer preference for reliable, fuel-efficient, and emission-compliant engine oils continues to reinforce the Asia Pacific's strong growth trajectory.
