According to Mordor Intelligence, the Asia Pacific base oil market size was valued at 17.42 million tons in 2025 and is estimated to grow from 17.75 million tons in 2026 to reach 19.49 million tons by 2031, at a CAGR of 1.89% during the forecast period (2026-2031).

This report is Segmented by Type (Group I, Group II, Group III, Group IV, and Other Types), Application (Engine Oils, Transmission and Gear Oils, Metalworking Fluids, Hydraulic Fluids, Greases, and Other Applications), and Geography (China, India, Japan, South Korea, ASEAN Countries, and Rest of Asia-Pacific). The Market Forecasts are Provided in Terms of Volume (Tons).
India's BS VI and China 6 standards limit sulfur to 10 ppm, forcing blenders to abandon Group I stocks for cleaner Group II alternatives. ExxonMobil's Singapore Resid Upgrade Project added 20,000 barrels per day of Group II capacity in September 2025 to serve this demand. Japan's JASO GLV-2 spec for ultra-high-viscosity-index oils is pushing Group III adoption in hybrids. Rural India and inland China still rely on Group I for price-sensitive segments, creating a parallel supply chain that will persist until 2028. Mid-tier refiners are fast-tracking hydrocracker revamps to stay relevant, yet cash-flow constraints limit upgrades to coastal assets.
China produced 30.2 million vehicles in 2024, with turbocharged engines exceeding 60% of output, up from 45% in 2020. Turbocharged units run hotter, so OEMs specify Group II or Group III oils to prevent oxidation. India's passenger-vehicle sales reached 4.2 million units in fiscal 2025, with SUVs claiming 48% of registrations. Carmakers such as Maruti Suzuki pre-fill engines with API SP oils, locking the aftermarket into premium grades. This preference compresses the addressable pool for Group I stocks, which now serve mostly heavy-duty diesel fleets.
Battery-electric vehicles need 70% less lubricant than gasoline cars, a reality most visible in China, where EV sales reached 9.5 million units in 2024, equal to 35% of passenger-car volume. Thailand hit EV price parity in 2024, and India's two-wheeler electrification rate is scaling fast. Commercial trucks and off-highway gear remain ICE-dominated, but passenger-car lubricant pools will continue shrinking, setting a ceiling on long-term Asia Pacific Base Oil market growth.

Group II held 38.05% of the Asia Pacific base oil market in 2025, owing to emission-driven demand for low-sulfur stocks. The Asia Pacific Base Oil market size for Group III is forecast to expand at a 3.30% CAGR, the fastest among all grades, propelled by turbocharged and hybrid powertrain requirements. ExxonMobil's new EHC 340 MAX extra-heavy Group II grade targets sectors that once relied on bright stock. Petronas and Pertamina's planned 800-tons-per-day Group III plant in Indonesia will deepen regional supply diversity. Margin gaps between Group II and Group III have narrowed to USD 150-200 per ton, encouraging blenders to switch applications without prohibitive cost penalties.
Legacy Group I capacity now supports niche heavy-duty diesel and industrial fluids, but continues to lose share. Indian Oil Corporation's Panipat revamp and HPCL's LOBS upgrades will convert significant Group I throughput into Group II and Group III by 2026, accelerating the trend. Group IV PAO remains below 5% of regional volume yet commands premium pricing in aerospace, while Group V naphthenics serve stable specialty segments. Overcapacity risks persist if new hydrofinish units outpace high-grade demand, but refinery rationalization in inland China may remove marginal Group I assets by 2029.
