Who Is S-Oil Really Trying to Reach?
S-Oil customers span three tiers: high-volume B2B industrial buyers, international energy traders and government wholesalers, and South Korea retail motorists served via service stations and loyalty programs.
Main customer group: Industrial petrochemical buyers
Petrochemical manufacturers buying feedstocks-paraxylene, benzene, propylene-are S-Oil's core industrial clients because they drive steady, high-volume demand and margin stability.
Secondary customer groups: Export markets and B2C retail
Exports were 54 percent of sales in 2024, targeting Asia – Pacific and the Americas via traders, wholesalers, and government buyers; domestically, millions of motorists buy fuel and lubricants at S-Oil service stations.
Customer type and market role
S-Oil serves a mixed base: primarily B2B for petrochemicals and industrial fuel, plus significant B2C retail fuel and lubricant customers in Korea and institutional energy buyers internationally.
Most important segment
Refining and petrochemical B2B clients remain most important by revenue; S-Oil is shifting emphasis toward high-value polymers-LLDPE and HDPE-to capture downstream margins as petrochemical capacity scales.
Who S-Oil Is Really Trying to Reach
S-Oil targets industrial petrochemical buyers, international energy buyers (export markets), and domestic retail motorists; industrial B2B buyers generate the largest, most strategic revenue streams.
- High-volume petrochemical manufacturers (paraxylene, benzene, propylene)

Secondary markets: US and East Asia
The United States is a high-growth export market: jet-fuel-driven exports rose 15 percent year-on-year to a record 49.6 million barrels in 2025. China remains pivotal for chemicals demand, especially polypropylene (PP) and propylene oxide (PO), tracked against stimulus measures.
Where S-Oil is strongest
S-Oil appears strongest in refined-products distribution and petrochemicals across Asia-Pacific, supported by steady diesel and jet-fuel offtake and established B2B channels for industrial and maritime customers.
Where demand is growing in 2025/2026
Fastest growth is in US aviation fuel exports and recovery-linked Chinese petrochemical demand; Southeast Asian diesel markets and Australian diesel imports remain structurally strong into 2026.

How Does S-Oil Keep Its Audience Growing?
S-Oil grows its audience by shifting from fuel to chemicals, entering plastics and textiles, and deepening B2B partnerships; it reaches adjacent segments through new polymer supply and retains clients with higher-margin lubricants and integrated commercial contracts.
Shaheen-driven market expansion
S-Oil targets new S-Oil customers in polymers by using the Shaheen TC2C conversion to lift chemical yield from 20% to 70%, adding 1.8 million tons/year of ethylene-about 13% of South Korea's output-and attracting plastics and textiles buyers.
Customer retention drivers
Retention rests on reliable high-margin lubricant growth (2025 upswing) and long-term supply contracts with polymer and automotive manufacturers as Shaheen scales to commercial operations in December 2026 (93.1% complete as of January 14, 2026).
Loyalty and repeat demand
Repeat demand comes from integrated downstream contracts for ethylene-derived resins and steady lubricant orders from OEMs; ecosystem stickiness increases as S-Oil clients and partners lock in multi-year offtakes.
Strongest growth lever
The Shaheen project's shift to Thermal Crude-to-Chemicals (TC2C) is the primary growth lever-by expanding S-Oil target markets into petrochemical clients and downstream polymer customers, it materially reduces fuel revenue dependence.
How Shaheen and Lubricant Growth Keep the Audience Growing
Shaheen transforms Who S-Oil serves by converting barrels into chemicals, bringing large polymer buyers and strengthening B2B ties while lubricant margin growth stabilizes revenue in 2025-2026.
- Primary growth driver: Shaheen TC2C converting chemical yield to 70%
- Strongest retention factor: multi-year supply contracts with polymer and lubricant clients
- Key loyalty mechanism: integrated offtake and commercial sales partnerships for ethylene-derived products
- Main risk: commissioning delays or lower-than-expected ethylene pricing that weaken S-Oil customers' demand
