Why it happens around High Coniscliffe
High Coniscliffe is part of the Darlington catchment, and the pattern here follows the wider area.
Darlington is unusual in sitting where two major routes cross. Calls come from long-leg fills at Scotch Corner and Barton Park, from Teesside Airport hire cars, and from a local residential pattern on the A167.
The backdrop is the crossroads of the A1(M) and the A66 — north–south and trans-Pennine traffic meeting in one town.
The roads that matter for High Coniscliffe are the A67. Most calls from here start on one of them.
Getting to you in High Coniscliffe

If it happens on the A67
The A67 follows the Tees valley and crosses quiet country with long gaps between forecourts. Teesside Airport sits on this road, and airport hire cars are one of the most reliable sources of misfuel work there is — an unfamiliar vehicle, no check of the paperwork, and a first fill made days later at whatever forecourt is nearest.
On a live carriageway the order is: get clear, call 999 or National Highways on 0300 123 5000 if the vehicle is in a running lane, and only then call us. The full road guide is here.
What the wrong fuel does on its way through
Diesel lubricates as it passes; petrol dissolves that film and acts as a solvent. Run a diesel high-pressure pump on petrol and it wears fast, shedding fine metal into the injectors behind it. None of that happens while the fuel sits in the tank. All of it starts the moment the engine turns over.
Westbound drivers face the Stainmore crossing on the A66 with effectively no fuel and serious exposure in winter. A vehicle that stops up there is a genuinely difficult recovery.

When it tends to happen
A high overnight share from the A1(M), which is characteristic of service-area misfuels, alongside an ordinary weekday local pattern.
The cost, honestly
There is one fixed figure and one variable. The fixed figure is the call-out; the variable is whether the engine ran, and for how long.
| Call-out | From just £89 misfuel callout fee |
|---|---|
| Engine never started | Usually the drain and flush only |
| Engine run briefly | Drain, flush, often a new fuel filter |
| Driven some distance | May need the high-pressure pump or injectors checking — a workshop job |
| When you hear the price | On the phone, before anyone travels |
Questions we get asked
Is there an out-of-hours surcharge?
The call-out is the call-out. Whatever the total is, you hear it on the phone before anyone travels.
Can I just top it up with the right fuel?
No. Dilution does not fix contamination, and driving to a filling station to try it is the mile that turns a drain into a repair.
How long will I be waiting?
Arrival depends where you are across DL1, DL2 and DL3 and what is already running. You get a realistic window on the call rather than an optimistic one.
What about a van or a hire car?
Same job. With a hire car, ring the hire company too — some policies cover a misfuel drain and it is worth knowing before you pay.
What if I have already driven it?
Still call. Most vehicles driven a short distance are recoverable. Tell us how far you got, because it changes the kit we bring.
Reviews, including the bad ones
4.8 out of 5 across 2,190 Trustpilot reviews. Praise clusters on two things — speed of arrival, and technicians who do not make a driver feel stupid about a mistake anyone can make.
The complaint that comes up most is cost. It is a fair thing to raise: the call-out is From just £89 misfuel callout fee, the full price is confirmed before a technician sets off, and if the job turns out to be different you are told before further work, not after.
