S-Oil is launching its premium lubricant brand, 'S-Oil Seven,' based on world-class lubricating oil competitiveness and is expanding its presence in the domestic and international premium lubricant markets.
On the 24th, S-Oil noted that its premium lubricant brand 'S-Oil Seven' was selected as the top in the engine oil institutional sector for the second consecutive year at the '2025 Korea Brand Hall of Fame.' The brand was recognized for ensuring outstanding lubrication performance and engine protection performance based on its self-produced high-quality base oils, while meeting diverse customer demands through a segmented product lineup for internal combustion engine vehicles, electric vehicles, and hybrid vehicles.
S-Oil has established itself as a major supplier of high-performance eco-friendly Group III lubricating oils globally. It produces all grades of lubricating oils according to international quality standards, including Groups I, II, and III, and boasts a production capacity of 44,700 barrels per day, the largest for a single plant in the world.
Since its establishment in 1976, S-Oil boldly invested in the premium lubricating oil business. It succeeded in localizing the high-quality lubricating oil that was previously entirely imported and has since led the domestic lubricating oil market.
In 2008, S-Oil established a joint venture lubricating oil specialized company, S-Oil Total Lubricants (STLC), with the French oil company Total. STLC produces and supplies various finished goods used in automotive and industrial applications. It is solidifying its position as the largest supplier to domestic automobile manufacturers.
A S-Oil official said, 'The premium lubricant 'S-Oil Seven' optimizes five functions required for engines: ▲ fuel efficiency improvement ▲ eco-friendliness ▲ smooth driving ▲ engine protection ▲ impurity removal, and it embodies the achievement of two customer values: improving vehicle functionality and enhancing driver satisfaction.' He noted that it is establishing itself as a 'top luxury brand.'
