Do Not Start The Engine
If the mistake is noticed at the pump, leave the ignition off. Tell forecourt staff and follow their instructions for moving the vehicle safely.
Do not push it alone in an active filling area. Starting or even switching on some vehicles can circulate the wrong fuel, which may turn a drain into a larger mechanical problem.
If The Engine Has Already Run
Stop as soon as it is safe and switch off. Do not try to reach home or use the remaining correct fuel to dilute the mistake.
Tell the assistance provider what fuel went in, how much was added, the vehicle details and whether the engine ran. Recovery may be safer than further driving.
Fuel Drain Cover And Engine Damage Are Different
A breakdown benefit or misfuelling add-on may pay for attendance, recovery or draining. A comprehensive car policy may treat resulting accidental damage separately.
Replacement fuel, parts and mechanical repairs may have different limits or exclusions. Ask each provider which cost it is considering before assuming one approval covers the whole event.
| Cost Or Event | Possible Route | Question To Ask |
|---|---|---|
| Ignition off | Damage may be more limited | Call suitable fuel-drain assistance |
| Engine started | Wrong fuel may have circulated | Stop safely and arrange recovery |
| Drain and recovery | Breakdown benefit may apply | Check limits and excluded costs |
| Resulting damage | Motor policy may assess separately | Notify insurer and retain diagnostics |
Which Policy Or Service To Call First
Check the breakdown membership, motor policy schedule and any add-on certificate. If a specialist fuel-drain service is included, use the stated number.
Where the engine has run or damage is suspected, notify the motor insurer under its reporting terms. Avoid authorising expensive work until the payer and limits are understood, unless urgent safety action is required.
Information The Recovery Team Will Need
Give the recovery team the key facts:
- Your location.
- The registration, make and model.
- The correct and wrong fuel types.
- The approximate quantity added.
- Whether the ignition or engine was used.
Mention warning lights or unusual running. Keep the forecourt receipt and attendance record because they establish timing and quantities more reliably than memory.
Costs To Clarify Before Work Begins
Ask about call-out, drain, disposal, replacement fuel, recovery and diagnostic charges. If the engine ran, ask how resulting damage will be assessed and what excess applies.
A breakdown attendance does not automatically remove a motor-policy excess. If the insurer pays, ask how the event and no claims discount may be recorded.
After The Fuel System Is Drained
Follow the technician's instructions before restarting. Keep the report and receipts, and arrange further checks if warning lights, noise or poor running continue.
Correct any claim information promptly if the estimated fuel quantity changes. At renewal, answer claims and incident questions using the insurer's wording and the final record.
How To Reduce The Chance Of Misfuelling
- Pause before lifting the pump.
- Check the fuel label on the car and nozzle.
- Avoid relying on nozzle colour alone.
- Use a prevention device only if it suits the vehicle.
A Simple Misfuelling Checklist
- Leave the engine and ignition off.
- Tell the forecourt staff.
- Check your breakdown and motor policy documents.
- Explain exactly what fuel went in and whether the engine ran.
- Confirm who will pay before authorising non-urgent work.
- Keep the fuel-drain and repair records.
Your breakdown cover may explain whether attendance, recovery or a fuel drain is included.

FAQs
What should I do after putting in the wrong fuel?
Do not start the engine. Tell the forecourt staff, move safely if instructed and call suitable assistance.
Does comprehensive insurance include misfuelling?
Some policies may, but others exclude it or limit the benefit. Check the wording.
Does breakdown cover pay for a fuel drain?
It may if misfuelling assistance is included. Standard roadside cover does not always include it.
Is engine damage covered?
That depends on the policy and circumstances. Fuel draining and resulting damage may be treated separately.
Will a misfuelling claim affect no claims bonus?
It could if the car insurer pays a claim. Ask how the claim will be recorded.
