About

This site is a free lookup service built to make it easy to find the cheapest gas station by region and fuel type.

Data source and update cycle

Price data comes from the Korea National Oil Corporation's Opinet public API. It's collected once a day, in batches from early morning through late morning: province/city level updates daily, while district level updates every two days per fuel type. Actual station prices may differ, so please confirm before visiting.

About the information shown

The regional list shows up to the 20 cheapest stations for the selected region and fuel type; highest-price sorting applies only within these 20. It's not a feature for finding the most expensive station in the whole region.

"Find near me" and distance sorting use nationwide station data to show stations within your location radius (3, 5, or 10km), sorted by distance or lowest price. This feature is only available once enough station coordinate data is ready, and some stations whose addresses couldn't be converted to coordinates may be excluded.

Self-service/full-service status, quality certification, and phone numbers are based on Opinet's business registration data, so newly opened or changed stations may take time to be reflected. Stations with no information show no badges. This information is current as of September 21, 2026. The "24h" badge only appears for stations whose business name literally contains "24-hour" (24시) in Korean; since official data doesn't include operating hours, please call ahead to confirm.

Distance is calculated on your own device using your browser's current location; your exact coordinates are never sent to the server (only an approximately 25km grid ID is requested to fetch nearby data).

Why do prices differ between stations?

Even within the same neighborhood, prices can differ by tens of won per liter depending on brand (refiner-operated vs. independent), rent, and the number of nearby competing stations. Self-service stations often cost less to operate in labor, making them cheaper than full-service stations, while stations near highway interchanges or in high-rent city centers tend to price higher. Even though refiners' supply prices are nearly uniform nationwide, these differences in each station's operating costs are reflected directly in the final selling price.

Frequently Asked Questions

What is Opinet?
A nationwide gas price disclosure system run by the Korea National Oil Corporation. Every gas station in Korea is legally required to report its selling prices, so the prices shown here are official data.

Are self-service stations always cheaper?
On average they tend to be cheaper, but there are many exceptions. Depending on region, brand, and timing, a full-service station can sometimes be cheaper, so it's more accurate to compare actual prices rather than relying on the self-service label alone.

Can I pay or earn points through this site?
No, this is a price-comparison service only. Actual refueling, payment, and point accumulation happen at each gas station or refiner's own app.
