Red diesel in a road vehicle in Mohill: the legal side
Stopped in Mohill with red diesel in the road diesel tank? Do not turn the key. Call 01295 380724. Unstarted this is a straightforward drain and a disposal note. The dye is the evidence, and it stains everything it touches. 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.
Our own units are UK-based, so in Mohill we take the consultation and put you straight through to a local drainer covering County Leitrim.
Figure 01 — Mechanism
Why red diesel and a road diesel system do not get on
Red diesel is ordinary gas oil carrying a marker dye and a rebated duty rate. Mechanically it is close to road diesel; legally it is not.
It burns, so the engine runs normally and nothing warns you. The exposure is a roadside dip test, the duty, the penalty and the seizure powers behind it.
Drivers in Mohill conceal this more often than they report it — the same study found embarrassment keeps incidents quiet, which is why every published prevalence figure is probably an undercount and why nobody should feel singular about it.
Red diesel in a road vehicle in mohill: the worst case
A marked-fuel penalty and vehicle restoration costs, on top of a full drain and flush to clear the dye.
Getting to you in Mohill
Mohill sits in County Leitrim, and a unit attends the whole of it. If you are closer to Carrick-on-Shannon, Manorhamilton, Drumshanbo or Ballinamore, the same applies: the vehicle is not moved, the technician travels. Give the operator a postcode, a forecourt name or a what3words address and that is enough to dispatch.

Mohill is in the Republic of Ireland, and our own drainage units are UK-based. What we do here is put you straight through to a local drainer covering County Leitrim, so you are not ringing round a search page while the vehicle sits on a forecourt.
The consultation is the same and it is still free. Tell us what went in, roughly how much, and whether the engine has run, and one of our engine scientists, fuel-system engineers and misfuel specialists will establish what is exposed before anyone is dispatched. The mechanism does not change at the Irish Sea: a high-pressure pump fails on petrol in Cork exactly as it does in Cardiff.
How it shows itself
Nothing. It burns, the engine runs normally, and that is the problem: the first sign is usually a roadside dip test.
What happens on site
Drained, flushed and disposed of under licence, with a waste transfer note. The dye stains the system, so the flush matters more here than the drain.
Published UK figures for the work run from about £120 for a straightforward drain to five figures where a vehicle was driven to a standstill. Establishing which end of that range applies to you is free.

How bad is it? Answer one question
Red diesel in the tank behaves differently depending on one thing only: how far through the fuel system it has travelled.
Figure 03 — Escalation
- 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 Mohill.
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.
