Wrong fuel in Darlington: what drives it locally
The defining feature of misfuelling around Darlington is the crossroads of the A1(M) and the A66 — north–south and trans-Pennine traffic meeting in one town.
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.
When: A high overnight share from the A1(M), which is characteristic of service-area misfuels, alongside an ordinary weekday local pattern.
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.
The corridors that produce most of the local volume are A1(M), A66, A167, A67, A68 and A688, and coverage runs across DL1, DL2 and DL3 from a single rota.
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.

What happens when you call
- Key out, hands off An engine that has never run on the wrong fuel is a drain and nothing more. That is the cheapest outcome available and it is still on the table right now.
- Do not move the vehicle Not into a bay, not onto the verge, not around the corner — unless it is genuinely unsafe where it is.
- Hazards on, tell someone Forecourt staff are used to this and are rarely difficult about it once they know how long you will be.
- Call 01293 248666 and be specific Vehicle, wrong fuel, rough quantity, engine started yes or no. Those four things determine the price, and you hear it before we travel.
- Drain, flush, refill, prime Carried out where the vehicle stands, anywhere across DL1, DL2 and DL3.
- Back on the road About an hour for a standard job. The waste fuel is removed under a transfer note that discharges your duty of care.
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.
Questions we get asked
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.
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.
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.
Do I need to stay with the vehicle?
Usually yes, so we can hand it back to you running. If you cannot stay, say so on the call and we will work out how to do it.
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.
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.
