High-octane premium gasoline brand
Wins quality satisfaction index for second consecutive year
'Reaffirms technological edge and customer trust'
GS Caltex announced Monday that its premium gasoline brand Kixx Prime has been named No. 1 in the premium gasoline category of the 2026 Korean Standards Quality Excellence Index, known as KS-QEI.
The KS-QEI, administered by the Korean Standards Association, is a quality evaluation index based on assessments by consumers and experts who have used a given product or service. GS Caltex has now claimed the top spot for two consecutive years. "This result reaffirms the technological capabilities and customer trust we have built up over many years," a company official said.
Kixx Prime is a high-octane premium gasoline that GS Caltex launched in 2006. The fuel contains high-performance engine detergents and friction-reducing agents designed to manage deposits inside the engine and cut energy losses caused by friction. These properties help reduce abnormal combustion, allowing the engine to maintain stable performance over extended use while delivering smooth acceleration and a refined driving experience.
Since launching Kixx Prime, GS Caltex has continuously upgraded its quality management systems. The company verifies product stability through collaboration and testing with a range of high-performance vehicle manufacturers, and works to maintain consistent quality across the entire process — from raw material procurement through production and supply.
GS Caltex said it plans to continue research and development and quality innovation to help improve vehicle performance and enhance driving satisfaction for customers.
"Kixx Prime being named No. 1 in the KS-QEI premium gasoline category for two consecutive years is a meaningful achievement born of steady quality improvement efforts and the trust of our customers," said Kim Chang-su, head of GS Caltex's Mobility & Marketing division. "We will continue to raise the driving value that customers can feel firsthand, backed by differentiated product quality and technological expertise."
