Nobody teaches you how to use a fuel station. It is assumed knowledge, which makes the first few visits quietly stressful — usually not because it is difficult, but because you are doing it in public with a queue behind you. Here is the whole sequence, including the parts people are too embarrassed to ask about.
Before you arrive: which side is the filler on?
Look at the fuel gauge on your dashboard. Next to the little pump symbol there is almost always a small triangle or arrow, and it points to the side of the car your filler cap is on. It is on nearly every modern car and almost nobody is told about it.
That one glance saves the manoeuvre everyone recognises: pulling up, opening the door, discovering the hose is on the wrong side, and reversing out again. If your car is older and has no arrow, check once in daylight and simply remember it.
Pulling up and switching off
Stop so your filler cap is roughly level with the pump — the hose has plenty of slack, so being a foot out either way is not a problem. Switch the engine off. This is a rule at essentially every station in the world, and it is not a formality.
Take the handbrake. If it is a busy forecourt, resist the urge to leave the car running "just for a second" while you go inside to pay.
Choosing the right nozzle
Check what your car takes before you touch anything. There is a label inside the filler flap on most cars stating the correct fuel, and it is there precisely because this matters.
Do not go by the colour of the pump handle. Colour conventions are not consistent between countries, and relying on them is a habit that works until the first time you drive abroad. In the EU and many neighbouring countries the dispensers carry shape-coded labels instead: a circle for petrol (E5, E10), a square for diesel (B7, XTL), a diamond for gaseous fuels (LPG, CNG, H2). Your car carries the matching label near the filler.
If you are unsure, stop and check. Putting the wrong fuel in is the one mistake at a fuel station that is genuinely expensive — and it is entirely avoidable by reading a label. We wrote up what to do if it happens.
Actually filling
Open the flap, unscrew the cap — many cars have a holder or tether on the flap to rest it in. Insert the nozzle fully, then squeeze the trigger. Most nozzles have a catch that holds the trigger open so you do not have to grip it the whole time.
The nozzle stops itself automatically when the tank is full. That click is the sensor doing its job, and it is your cue to stop.
Do not keep topping up after the click. Cars have a system that captures fuel vapour so it does not vent into the air, and it is not designed to receive liquid fuel. Squeezing in extra after the cut-off can push fuel where it does not belong, and that is an emissions-system repair for the sake of a fraction of a tank. Stop when the pump stops.
Return the nozzle to the pump, screw the cap back on until it clicks, and close the flap. A cap that is not fully seated is a common cause of a warning light appearing a day or two later.
Paying
How this works varies more than people expect, so it is worth knowing the three patterns you will meet:
- Fill then pay inside — common in much of Europe. Note your pump number; the cashier will ask for it.
- Pay at the pump by card — you authorise before filling. The station usually places a temporary hold on your card for more than you will spend, then adjusts it to the real amount. The hold can take a few days to clear, which surprises people the first time.
- Prepay — common at night and in some countries by default. You pay a set amount first and the pump stops there.
In a few places you may not be permitted to pump the fuel yourself at all, and an attendant does it. If you arrive somewhere and everyone is sitting in their cars, that is usually why.
The small habits worth building now
- Touch the metal of your car door before picking up the nozzle — this discharges any static you have built up. It is a genuine safety measure, not folklore.
- Stay outside the car while filling. Getting back in and out again on a dry day is exactly how static builds.
- No smoking, no naked flames — this needs no explanation, but it does need obeying.
- Do not fill a container that is not designed for fuel, and never fill one inside the car or in the boot.
- Refuel before you are desperate. Filling at a quarter tank rather than on the warning light means you choose the station, rather than the station choosing you.
If something goes wrong
You spill a little: tell the staff — forecourts have absorbent granules and it is a routine event. The pump does not respond: try another; they fail individually. You cannot open the filler flap: many cars have a release inside the cabin, often near the driver's seat or in the boot.
And if you are simply unsure about something, ask the staff. They answer these questions constantly and would far rather explain than deal with the consequences of a guess.
