Misfuelling at a petrol station in Scotland happens more often than you’d think, but you can handle it if you act quickly. Leave the engine switched off immediately and don’t turn the key.
This guide covers what to say to staff, what comes next, and what you can expect from the station. If you need help, call 0800 246 5297 or arrange wrong fuel recovery.
Step 1: Tell the Forecourt Staff Straight Away
(For Illustrative Purposes Only)
When you realise you’ve put the wrong fuel in, head inside and let a member of staff know. Don’t let embarrassment slow you down; it’s a common mistake, and staff have seen it before.
If you haven’t turned the ignition on, just leave the car where it is. Staff will tell you if it needs to be moved somewhere safe and may help you push it if necessary.
If you haven’t paid yet, settle up or speak to staff about the situation. Even though it’s the wrong fuel, you’re still responsible for the cost.
Let them know which pump you used. That way, they can take it out of use and prevent anyone else from making the same mistake.
Step 2: Ask staff to take the pump out of use
(For Illustrative Purposes Only)
If your car’s still at the pump, talk to staff. Ask if you should move it or if they can place a cone or just take the pump offline for now. This helps keep things running smoothly for everyone else.
Jot down the pump number and time. Hang on to your fuel receipt too. These details might help if you need to explain things to your insurer or breakdown provider.
Stick to the facts. If it’s a typical case like petrol in a diesel vehicle or diesel in a petrol car, the responsibility is usually on you, not the station. Don’t start the engine; the wrong fuel can mess with the fuel pump, injection system, spark plugs, and engine. If AdBlue contamination is a factor, mention that to your recovery provider as well.
Step 3: Don’t move the vehicle off the forecourt until drained
(For Illustrative Purposes Only)
The big question is whether you’ve started the engine. If the wrong fuel is just sitting in the tank and you haven’t run the engine, the contamination hasn’t spread, so the engine’s still safe.
Seriously, don’t turn the key, even if you just want to move the car a couple of metres. If you need to clear a pump, only push the car with help and when it’s safe.
In diesel cars, fuel lubricates the high-pressure pump. Petrol strips away that lubrication, so starting the engine can spread the contaminated fuel and cause real damage fast. Don’t try to dilute the wrong fuel by adding more of the correct one; that just means there’s more to drain.
Call us; our mobile technician will come out, drain the tank, flush the system, and refill with clean fuel. Then you’re good to go; no tow required. For help with wrong fuel in your car, call 0800 246 5297.
What the petrol station will and will not do
(For Illustrative Purposes Only)
Staff usually let you know where to wait, help keep things safe, and allow a recovery technician to work on your car. Our mobile fuel drain technician will handle the contaminated fuel. Most staff have dealt with misfuelling before and work with the fuel drain service without fuss.
The station doesn’t have any special legal duty to drain your tank or follow a set misfuelling procedure. Their job is to keep the place reasonably safe and make sure pumps measure fuel accurately. Trading Standards checks for pump accuracy.
No law requires specific fuel labels on pumps. It’s up to you to pick the right fuel, so if you misfuel, it’s generally not the station’s fault.
If you suspect a pump gave you the wrong fuel despite your selection, report it to Trading Standards or Citizens Advice Scotland. That’s rare, but if it happens, arrange vehicle recovery or a drain by calling 0800 246 5297. Technicians should follow safety standards; PAS 43 is the British standard for recovery operations. This isn’t legal advice, just practical info.
Getting a copy of the CCTV footage (useful for insurance claims)
(For Illustrative Purposes Only)
You can ask the petrol station about CCTV and request footage under data protection rules. The station will have its own process and might ask for details like the date, time, and what you looked like. They don’t have to hand over footage on the spot.
Recordings only stick around for a limited time, so ask quickly if you need them. Privacy rules or ongoing investigations can also affect what you can get.
Most of the time, CCTV isn’t necessary for a straightforward misfuel. It might help if you’re disputing a rare pump fault or need extra support for an insurance claim. Often, your receipt and a note of the time do the job better than chasing footage.
This applies whether you stopped near Glasgow, the M8, M74, M77, M80, or A9. If you ended up on a hard shoulder or in an emergency refuge area, keep records of any wrong fuel recovery service you used.
Frequently Asked Questions
Keep the engine off, don’t drive, and arrange a mobile fuel drain. Station staff will help with safety, and insurance coverage depends on your policy and the details of what happened.
What should I do immediately after putting the wrong fuel in my car?
Leave the engine off, don’t turn the key, let the staff know, and don’t move the car under its own power. Call a mobile drain technician.
Can I drive my vehicle if I have accidentally used the wrong fuel?
No. Driving pulls contaminated fuel through the system and can turn a simple drain into a repair. If the engine stays off, you avoid damage.
If the pump was mislabelled, is the petrol station responsible?
The cost depends on your vehicle and how much fuel went in. There’s no call-out fee, and you get the confirmed price before work begins.
Will my insurance cover the cost of damage caused by putting in the wrong fuel?
Maybe, but it depends on your policy and coverage level. Check your insurance. Keep any written reports and receipts to support your claim. This is general information, not advice.
What happens if I use petrol in a diesel car or diesel in a petrol car?
Petrol in a diesel car is more serious because petrol removes lubrication from the fuel pump. Diesel in a petrol car is less serious, but you still need to drain the system.
Can a Scottish petrol station help if I have filled my vehicle with the wrong fuel?
Staff can make sure the area stays safe. They’ll also let a technician onto the forecourt, but they won’t drain the fuel for you.
Call a specialist mobile technician on 0800 246 5297.
