Screen wash in the diesel tank in Barmulloch: the expensive one
Screen wash in the diesel tank in Barmulloch: do not start the engine, and call 01295 380724. Unstarted this is a straightforward drain and flush, and the difference between that and a pump rebuild is one turn of the key. Talking it through with one of our engine scientists, fuel-system engineers and misfuel specialists costs nothing, and the drain itself takes 45 to 90 minutes once someone is on site.
Starting the engine is the single decision that changes both the outcome and the cost.
What is actually happening in the tank
Screen wash is water, alcohol and surfactant. A diesel high-pressure pump is lubricated only by the fuel passing through it.
Lubricity collapses immediately: water and alcohol carry none. The pump wears within minutes and sends debris forward into the rail and injectors.
Misfuelling clusters where attention breaks: supermarket forecourts at the end of the working day, a hire car collected in a hurry, the first tank after changing vehicle. Nothing about Barmulloch makes it unusual — the error is designed into the forecourt, not into the driver.

Barmulloch: the practical detail
Barmulloch covers G21, and a unit attends any of them. If you are closer to Anderston, Anniesland, Ardlui or Anderston Glasgow, the same applies: the vehicle is not moved, the technician travels. The pickup point is wherever the vehicle already is, including a hard shoulder, a driveway or a multi-storey.

How it shows itself
A sharp loss of power, knocking, and a cut-out that arrives faster than with petrol because nothing in screen wash lubricates anything.
The work itself
Full drain and flush, new filter, and an assessment of the high-pressure pump and rail for wear and debris if the engine ran at all.
Nothing about this is unusual and nothing about it is urgent in the way it feels — provided the engine stays off.
What has happened so far?
Pick the one that fits. It is the only question that changes the answer.
- TankThe wrong fuel is sitting still. Nothing downstream has touched it.
- Lift pumpTurning the key runs the in-tank pump, and the contamination starts moving.
- FilterThe filter takes the first hit and is replaced either way.
- High-pressure pumpLubrication fails here first. This is the component that turns a drain into a rebuild.
- Injectors and railDebris from the pump arrives here. At this point the fuel system is replaced, not cleaned.
Fuel Fixer, the company behind UK Wrong Fuel Repository, holds a rating of 4.8 out of 5 from 2,190 reviews on Trustpilot, on a profile claimed since 2017.
Across recent reviews, the themes customers raise most often are staff who stay polite, professional and reassuring during what is a stressful situation, and how quickly a technician arrives and gets the vehicle back on the road in Barmulloch.
The most common criticism is price. Some customers have felt the cost of an emergency drain was steep for a job that takes under two hours, and that is fair comment on an emergency call-out. It is why the misfuel call-out fee is free and why published repair figures span two orders of magnitude before a technician sets off — so nothing about the cost is a surprise at the roadside.
