Tell us whether the van is petrol or diesel, what went into which tank and whether it has run. If it is hired, leased or company-owned, identify who is authorised to approve the work before the technician attends. A driver and a fleet manager may need different information from the same callout.

Petrol, diesel and AdBlue mistakes in vans
Drivers who regularly switch vehicles may encounter different fuel types, filler layouts or AdBlue positions. Petrol in diesel and diesel in petrol are not the same problem as AdBlue in a fuel tank. Name the actual fluid and filler used rather than describing every incident simply as a misfuel.
If you noticed at the pump, leave the engine off. If you have already driven, stop safely and explain how far the van travelled, any warning messages and whether it stopped itself. Keep the receipt or container, and tell us if anything else has been added since the mistake.
Working around the van and its load
Access can be affected by the van’s size, weight, roof height, trailer and cargo. Let us know about height barriers, restricted parking, a loading bay, a trailer that cannot be uncoupled or a location where the vehicle cannot be left unattended.
Do not move a misfuelled van using its engine solely to make room for the technician. If it is obstructing a forecourt, depot or active traffic area, discuss a safe arrangement with the site staff or operator. The ability to attend does not override the need for a suitable working location.
Hired, leased and fleet vans
Check the operator’s incident process and provide a contact who can authorise work. A rental agreement or fleet policy may require notification or a particular repair route. Giving that information at the outset helps avoid a technician arriving while approval is still unresolved.
For a fleet enquiry, provide the vehicle or asset number, driver contact arrangements and any purchase-order requirement. Confirm who will receive the assessment and cost information. Account terms, response commitments and payment arrangements should be discussed rather than assumed.
Assessment before returning to work
The next step depends on whether the van has run and what is found. Tank draining, cleaning and further fuel-system checks may be needed. Where component damage or another fault is suspected, additional workshop attention may be appropriate.
A business schedule cannot establish that a vehicle is fit to keep driving. Ask what has been checked and whether there are any further recommendations before the van resumes its route. Arrival and completion estimates are specific to the job, especially for remote sites or island locations.
Attendance, access and the cost of the work
Commercial, HGV and plant enquiries are individually scoped. Tank volume, vehicle or machine configuration, site permissions, equipment and travel affect the quote. A starting price for a standard car drain does not apply automatically.
We cover mainland Scotland and the islands. Arrival estimates are confirmed for the vehicle’s actual location and current availability. Time on site is a separate matter and depends on the work. Neither a coverage page nor an initial enquiry is a promise of a fixed completion time.
Before attendance, identify the person authorised to approve the work. The technician explains the proposed service and confirms the cost before starting. If you intend to use a policy, lease agreement or hire-company process, check its requirements with the provider.
Find your coverage areaWrong fuel in a van: common questions
Can you attend at a customer’s address?
We can discuss attendance there, provided there is permission, safe access and a suitable working position. Tell us the actual address and any parking restrictions.
Do I need permission from the hire company?
Follow the hire company’s terms and incident procedure. Tell us who owns the van and who can approve work, so assistance is arranged on the correct basis.
Is an AdBlue mistake covered by the same procedure?
AdBlue contamination needs its own assessment. Explain whether AdBlue went into the diesel tank, petrol tank or another filler; do not assume a standard mixed-fuel drain is sufficient.
Can you guarantee the van will finish its route?
No. The vehicle must be assessed. We can discuss assistance and likely work, but condition, contamination, access and any damage determine the outcome.
