Steps for Refueling in the USA
In the United States, prepaying for fuel or authorizing your payment card before pumping is standard practice.
Pumps are equipped with integrated card readers for this purpose. Insert your card and select “Credit” (even if you are using a debit card). For verification, the system may ask for your PIN or a ZIP code. If your actual billing ZIP code or your hotel’s ZIP code is not accepted, you will need to see the attendant inside to authorize the pump.
Once the card is successfully authorized, remove it and insert the fuel nozzle into your car. At some older stations, you may need to manually lift a lever on the pump base to activate it. If the pump offers multiple grades, select the correct one by pressing the corresponding button.
A receipt is typically available at the pump after refueling.
If your card is declined at the pump, try selecting “Debit” instead. If that fails, proceed to the cashier to prepay. To fill the tank of a standard vehicle, authorizing $100 is usually sufficient. You can authorize a higher amount if necessary; any unused funds will be released back to your card shortly after you finish pumping.

Fuel Names in the USA
American gas stations typically offer three grades of gasoline, differentiated by their octane rating and price. Labels may vary slightly by brand.
🟠 Regular (87 Octane)
Regular is the standard and least expensive option, generally with an octane rating of 87. It is often simply labeled as Unleaded.
🔴 Mid-Grade (89-90 Octane)
Mid-grade gasoline offers slightly higher quality with an octane rating of 89-90. Common labels include Special, Unleaded Plus, or simply Plus (often seen at Exxon and Shell).
🔵 Premium (91-94 Octane)
Premium fuel is the highest grade, designed for sports cars or vehicles with high-performance engines. It typically features an octane rating of 91-94 and may be labeled as Unleaded Premium, Supreme (Exxon), or V-Power (Shell).
🟢 Diesel in the USA
When driving in the USA, you will rarely encounter diesel-powered rental cars. Diesel pumps are available at select stations and are primarily used by commercial trucks and large buses.
🔢 Octane Ratings in the USA
The U.S. uses the RON (Research Octane Number) system to measure octane, whereas Europe typically uses a mix of RON and MON. As a rule of thumb, add about 5 points to the American number to find the European equivalent. For most rental cars, Regular gasoline is perfectly adequate.

Gas Prices in the USA 2026
Gas prices in the United States are listed per gallon (1 gallon = 3.785 liters).
At many stations, the price per gallon varies based on your payment method. Paying with cash is often cheaper than paying with a credit card, as stations pass the processing fees on to the consumer. The difference is typically around $0.100 per gallon. Stations that do not accept cards will clearly display this restriction.
Fuel is generally cheaper in oil-producing states like Texas and Oklahoma, while prices are significantly higher in states like California and Hawaii due to taxes and transportation costs. Because U.S. fuel taxes are relatively low compared to Europe, pump prices are heavily influenced by global oil market fluctuations.

How to Use a Self-Service Pump in the USA
At most gas stations, you will use a self-service pump to refuel without assistance. Insert your payment card into the reader and remove it quickly. Unlike many ATMs, you do not leave the card inside the machine.
Follow the on-screen prompts. You may be asked to enter your ZIP code for security. Once approved, lift the nozzle, select your fuel grade by pressing the button, and begin fueling. When the tank is full, the pump will stop automatically. Return the nozzle to the cradle to complete the transaction.

I had two embossed MasterCard debit cards, and an embossed Visa credit card. I tried my luck on the rack regularly. I succeeded once out of about 15 attempts. Many times it even got to the point that Debit card accepted, I entered my PIN, then it would chug for a while and still get “Please see cashier”. So I guess. I solved it by taking the $30 cash, prepaid at the counter, pumped and went.
It’s weird because there was no problem with this at stores, parking meters of various kinds, McDonalds, etc.. anywhere.
As for the aforementioned coffee, for 1,5USD you usually get a half-liter cup full of tasty coffee, where I always put two nut milks, stoppered and sipped 200 km later… It’s great.
