S-OIL was founded in 1976 and has developed management characteristics with international scale matching mobility and management strategy to develop as a competitive global oil refining company.
1.Oil Refining Business - In 1980, S-OIL began commercial operation of its first oil refinery with a capacity of 90,000 barrels/day. Since then, it has doubled the number of refining facilities and today S-OIL is a major oil refining company. Refining capacity 669,000 barrels/day. In addition, the company actively operates light oil desulfurization facilities and gasoline production facilities. Also, the company has operated two units of Residue Hydro-Degassing (RHDS) facilities for the production of high value added products. From November 2018, the facilities of the waste hydro-degasification (No. 3 RHDS) and high-gravity fluid catalytic cracking (HS-FCC) units began to operate. With this, S-OIL was able to optimize the entire production line and obtain high value-added products, and firmly established itself as a leading global oil refining company.
2. Lubricating Oil Manufacturing Activity - Since its establishment as the first lubricating oil refinery in South Korea, S-OIL Corporation has created a milestone in the South Korean base oil market, which until 1976 was completely dependent on imported petroleum products, but today is one of the same products It is a leading supplier in the global market. S-OIL is the only company in South Korea that has a complete range of Ⅰ/Ⅱ/Ⅲ group base oils and is globally positioned as one of the world-class manufacturers supplying high-quality base oils not only to the Asian, but also to the European Union and North American markets. .
3. Lubricating oils - "We respond to the various demands of the market as a result of continuous change and development". Since S-OIL started its lubricating oil business in 1989, S-OIL has established itself as a leading company in the local market in a short period of time through continuous efforts and innovative ways. S-OIL is diversifying its product and brand portfolio in line with the changing market climate. With the launch of the DRAGON brand in 1989, SSU in 2005 and S-OIL 7 in 2014, the company has been leading market trends in the production of high quality and classy products. Accordingly, in 2019, the company united all its brands under one name - S-OIL 7, which further strengthened the brand image and once again emphasized the quality premium of the entire enterprise line of S-OIL. In the industrial oil segment, S-OIL expands its line to meet the requirements of various industrial sub-segments such as hydraulic oil, compressor oil and transmission oils, while benefiting from highly advanced technology in the production of lubricating oil.
4. Petrochemical activities - Along with oil refining and lubricating oil production activities, S-OIL has the best competitiveness in the field of petrochemicals, which it achieves through business diversification. For continuous growth, S-OIL mainly focuses on increasing the qualitative value of the manufactured products. As a result, with the commercial operation of the BTX plant and naphtha reformer in April 1991, the basis for business diversification into petrochemicals was created. Also, in December 1997, the construction of the Xylene Center was completed on the existing territory of the factory, which produces 700,000 tons of para-xylene (currently 740,000 tons), as a result of which the company officially entered the field of petrochemicals. In particular, this plant not only reduced the investment cost per unit, but also ensured the creation of a petrochemical product of the BTX process, which was Para-Xylene, which has a high competitiveness in terms of material charge.

In the 25 years since its debut in the lubricants business, S-OIL has acquired extensive experience in the development and production of lubricants within the framework of cooperation with the world's leading automotive companies. S-OIL provides a wide range of engine and transmission oils on its own production conveyor for leading car manufacturers. Including Hyundai-Kia Motors, GM Korea, Renault Samsung Motors, Ssangyong Motor, Toyota, Lexus, etc. We regularly supply Hyundai-Kia Motors with light vehicle gasoline and diesel engine oils for factory primary filling, and a few years ago, we started supplying high-quality and eco-friendly diesel commercial engine oils that meet Euro VI, the latest emission standard.
