LUBE OIL BUSINESS Lube base Oil

Overview

Ever since its foundation in 1976 as the first lube base oil refinery in South Korea, S-OIL Corporation set a milestone in South Korean base oil market which entirely depended on import and has been a leading supplier of lube base oil in South Korea as well as global market.

S-OIL has 44,700 barrels per day of production capacity with #1 LBO Plant (aramcoDURA / aramcoPRIMA) and #2 LBO Plant (aramcoULTRA).

S-OIL is the only company which has full line-up of Group Ⅰ/Ⅱ/Ⅲ base oil products in South Korea and is positioned as one of the world class manufacturers supplying high quality base oils to global market not only Asia but also EU and North America.

S-OIL, in association with Saudi Aramco and its affiliates (Motiva and Luberef), officially launched 'Aramco Base Oils Alliance' in 2019. Under a brand license agreement with Saudi Aramco, the alliance offers Saudi Aramco base oil brand : aramcoDURA (Group Ⅰ), aramcoPRIMA (Group Ⅱ) and aramcoULTRA (Group Ⅲ). Not to mention its business scale, the alliance will lead the industry in terms of technology, one of the crucial factors in base oil business, through close collaboration on research and development (R&D).
