A local number, not a local building

The number at the top of this page is answered by the people who send technicians to Carlisle. That is what the word local is doing here. It is not standing in for a depot, because Wrong Fuel Carlisle does not have one — the van comes to CA1 to CA6 and the work happens where you are stood. Call 01293 248666.

Will a little gas hurt a diesel engine: what to do

Five litres, twenty litres, a splash — why the amount matters less than the key.

Why the engine matters more than the litres

People assume a splash is fine and a full tank is a disaster. It is the other way round. Wrong fuel sitting in a tank is inert — it is a drain. Turn the key and it travels: lift pump, filter, high-pressure pump, injectors, and every stage it reaches adds a component to the bill. Five litres burned is worse than fifty litres left alone.

Step by step

  1. 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.
  2. Leave the vehicle where it stopped Pushing or coasting is still movement, and movement is how contaminated fuel finds the pickup.
  3. Sort out safety Hazards, and get people out of the vehicle if you are anywhere near moving traffic.
  4. 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.
  5. The job itself Extract, flush, refill, prime, run up, check. Roughly an hour on a standard vehicle.
  6. Old fuel away, invoice done Controlled waste, transfer note, registered carrier. Keep the note — it is what protects you.

Questions we get asked

How long will I be waiting?

Arrival depends where you are across CA1 to CA6 and what is already running. You get a realistic window on the call rather than an optimistic one.

How much does it cost in Carlisle?

Call-out £89 to £199, drain £199 to £1,999. The full price for your vehicle is confirmed on the phone before a technician sets off, so there is no surprise when we arrive.

What if it is not safe to drain where I am?

Then we tell you that on the phone rather than after arriving. Being told honestly costs nothing; being told on arrival costs a call-out.

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.
