Misfuelled a hire car in Durham? What to do first
Misfuelled a hire car? Do not start it, then ring the hire company before you ring anyone else — many hire agreements set out exactly who is allowed to drain it. Call 01293 248666.

Why hire cars are misfuelled so often
An unfamiliar car, collected that day, with a fuel type you did not choose. Hire cars are among the most reliable sources of misfuel work anywhere, because the driver has no habit to fall back on and often never checked the paperwork. Airport and station hires around Durham are particularly prone to it.
Ring the hire company first
Many agreements specify what happens after a misfuel — some have their own contractor, some allow you to use a local drainer and reclaim, some charge a fixed penalty regardless. Knowing which before you authorise any work saves an argument later.
If they tell you to sort it yourself
Then it is the same job as any other: a drain, a flush and a prime, where the car stands. Keep the invoice and the waste transfer note — the hire company will usually want both.
Around Durham
Durham calls split between motorway traffic at Durham Services and Belmont, a university population that turns over every September, and the former coalfield towns where distances to a main dealer are long. A pronounced overnight share from the A1(M), a September spike from the university, and a steady weekday pattern on the A690 and A167.
That applies across the villages we cover, including Kelloe, Croxdale, Hett, Sunderland Bridge, Tudhoe, Byers Green, Willington, Stonebridge, Langley Park, Esh, Quebec and Cornsay.
- Do not start it — that is the whole thing Everything else on this list is detail. This one line is the difference between a call-out and a pump.
- Leave the vehicle where it stopped Pushing or coasting is still movement, and movement is how contaminated fuel finds the pickup.
- Sort out safety Hazards, and get people out of the vehicle if you are anywhere near moving traffic.
- Call 01293 248666 Answered around the clock. Tell us what went in and whether it ran; you get the full price before a technician sets off.
- The job itself Extract, flush, refill, prime, run up, check. Roughly an hour on a standard vehicle.
- Old fuel away, invoice done Controlled waste, transfer note, registered carrier. Keep the note — it is what protects you.
What actually happens inside the fuel system
Fuel leaves the tank through the lift pump, passes the filter, reaches the high-pressure pump and then the injectors. Petrol in a diesel system strips the lubrication that high-pressure pump depends on, and metal shed by the pump travels downstream into the injectors. That sequence is the whole story: cost depends on whether the engine ran, and for how long, not on how many litres went in.
Durham sits at the centre of a wide rural catchment. Once you are out towards Consett, Crook or the coast, the nearest dealer is a long way off and a mobile drain is comfortably the faster option.

The cost, honestly
Here is how the price actually moves. None of it depends on how many litres of the wrong fuel went in — all of it depends on whether the engine ran.
| 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
Can you come to a supermarket forecourt?
Yes, and it is where a good proportion of jobs happen. Tell the cashier a drainer is on the way; they are used to it.
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.
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.
How much does it cost in Durham?
From just £89 misfuel callout fee. The full price for your vehicle is confirmed on the phone before a technician sets off, so there is no surprise when we arrive.
Will it have done damage?
If the engine was never started, damage is unlikely. If it ran, the risk rises with the distance driven — which is exactly why we ask.
Rated 4.8 out of 5
From 2,190 Trustpilot reviews. Reviewers consistently pick out arrival times and the fact that technicians talk them through what happened rather than just taking the keys.
Where reviews are critical, it is almost always about price. Rather than ignore that: the call-out is From just £89 misfuel callout fee, quoted in full on the phone before travel, and we would rather lose the job on the call than argue about it on the forecourt.
