According to S-Oil TotalEnergies Lubricants on July 10, S-OIL 7 secured the top position in all six evaluation criteria: brand awareness, image, benefits, leadership, brand loyalty, and social responsibility. KS-PBI is a brand value assessment index jointly developed by the Korean Standards Association and Seoul National University's Business Research Institute, which selects top-tier brands by industry based on a consumer research panel of approximately 120,000 Korean participants and expert evaluations.

With this award, S-OIL 7 has achieved the No. 1 position for two consecutive years since the engine oil category was first introduced last year. Following the awards ceremony, advertisements related to the award will be released through various media, including newspapers, subways, and bus shelters.

S-OIL 7 is a product that offers excellent lubrication and engine protection performance based on premium base oils. It features a range of products tailored to different uses, such as 'Gold' for gasoline and diesel, 'Red' for gasoline and LPG vehicles, and 'Blue' and 'Black' for commercial diesel vehicles, with further classification by performance levels such as #9, #7, and #5.

Recently, in line with the expanding hybrid vehicle market, S-OIL 7 has been strengthening its entry into the eco-friendly engine oil market by introducing 'S-OIL 7 EV Hybrid' as its flagship product. This 100% synthetic engine oil prevents low-speed pre-ignition (LSPI) and reduces timing chain wear, providing optimal performance for hybrid vehicles, which frequently start and stop and operate at both low and high speeds, according to the company.

The brand is also actively conducting marketing activities to expand brand awareness. Since 2024, S-OIL 7 has sponsored a team participating in the Superrace Championship 'Super 6000 Class', and starting this year, it is supplying hybrid engine oil to the 'Prius PHEV Class', Korea's only plug-in hybrid race.

Olivier Bellion, CEO of STLC, said, "S-OIL 7's selection as No. 1 in the KS-PBI engine oil category for two consecutive years is a meaningful achievement that demonstrates consumer trust in our product quality and brand," adding, "We will continue to deliver high-quality products and differentiated brand experiences that meet the evolving automotive market and customer needs."
