Self-service petrol pumps enjoy rising popularity in KoreaAudio version
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 petrol stations to reduce personnel expenses due to falling sales," the association said.
As of last Sunday, drivers could save W88.58 per liter by heading to a self-service gas station, where petrol was selling for W1,892.
