S-OIL, established in 1976 has grown into one of the most competitive oil refiners in the Asia-Pacific region by establishing profitability-oriented management strategies and nurturing dynamic and progressive spirit in the management. We operate the oil refinery facility with the capacity of 669,000 barrels per day (BPD) and other facilities that can produce petrochemicals and lube base oil in the Onsan Refinery in Ulsan. We are strengthening our status as a leader in protecting customers and the environment by producing and supplying the best quality oil products based on the world-class Bunker-C Cracking Center (BCC) and the Xylene Center, a PX plant with the world’s highest production capacity for a single facility.

S-OIL is not only a leader in the local lube base oil market, but also a globally competitive lube base oil maker as it has made bold investments in the high-quality lube base oil business since its foundation succeeding in domestically producing premium lube base oil. S-OIL Total Lubricants, a joint venture with TOTAL Raffinage Marketing S.A. in 2008, has clearly positioned itself as a leader in the domestic lubricant market as well.
