Why confirming your correct fuel type matters before you start driving
Using the wrong fuel type in a vehicle can cause serious mechanical problems, making it genuinely important to confirm whether your specific rental car requires gasoline or diesel before your first fill-up, rather than assuming or guessing based on general habits from home.
Understanding Korea's gas station color coding
While specific conventions can vary somewhat, gas stations generally use a consistent visual color system to help drivers distinguish between gasoline and diesel pumps, and taking a moment to confirm you're at the correct pump before beginning to fuel helps prevent a costly mistake.
Navigating self-service pump operation
Following the on-screen or posted instructions at a self-service pump, which generally guide you through fuel type selection, payment, and the fueling process itself, makes this a manageable task even without prior experience using self-service stations.
Using attendant-service stations if you prefer
At stations with attendant service, simply communicating your correct fuel type and preferred payment method to staff lets them handle the fueling process for you, offering a more hands-off alternative for drivers less comfortable with self-service.

Frequently asked questions
How do I know whether my rental car takes gasoline or diesel?
Checking your rental agreement paperwork or the fuel cap area of the vehicle itself, which typically indicates the correct fuel type, and confirming this detail with rental staff at pickup if you're at all uncertain, helps you avoid the serious problem of using the wrong fuel type.
What do the color codes at Korean gas stations generally indicate?
Korean gas stations generally use a consistent color-coding system to visually distinguish gasoline pumps from diesel pumps, helping drivers quickly identify the correct pump, though familiarizing yourself with the specific current color convention at a station before fueling is a sensible precaution given some variation can exist.
Are most gas stations in Korea self-service, or is attendant service more common?
Both self-service and attendant-service stations exist throughout Korea, with self-service generally being straightforward to use once you understand the basic process, while attendant-service stations simply require communicating your fuel type and payment method to staff.
