How bad is it to put unleaded in a diesel
How bad is it to put unleaded in a diesel? Same job as petrol in diesel, under the word on the pump. Do not start the engine; we drain it on site. Call 01293 248666 — a mobile technician comes to the vehicle anywhere across CA1 to CA6. Call-out £89 to £199, drain £199 to £1,999.
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.

How bad is it to put unleaded in a diesel: what to do
The same failure, under the wording on the pump.
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
- Freeze, then think The reflex is to start up and drive somewhere sensible. Resist it. Nothing about the situation gets worse while the engine stays off.
- Where you are is fine A forecourt bay, a kerb, a car park: all workable. Only move if staying put is genuinely dangerous.
- Hazards and a quick word Switch the hazards on and tell anyone who needs to know — cashier, passengers, the driver behind.
- Ring 01293 248666 with four facts Make, wrong fuel, rough quantity, started or not. Those four facts set the price you are quoted before dispatch.
- A technician arrives equipped Pump, sealed waste drum, fresh fuel and priming kit all come in the van. Nothing is towed.
- Drive off, document in hand About an hour for a typical job, then a waste transfer note for the old fuel, which is worth keeping.

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.
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.
