Self-service gas stations, which offer slightly cheaper prices, are growing in popularity here. According to the Korea Oil Station Association on Tuesday, as of the end of May, their number rose to 775 from 334 a year earlier, accounting for 5.8 percent of the nation's total gas pumps.
Their numbers have steadily increased from 464 last August to 636 in December and 763 in April. They offer gasoline at prices W40-W90 cheaper per liter (US$1=W1,144) than other stations.
"This rise can be attributed to increased interest from cost-conscious drivers, as well as efforts by gas stations to reduce personnel expenses due to falling sales," the association said.
As of Sunday, drivers could save W88.58 per liter by heading to a self-service gas station, where petrol was selling for W1,892.
