## What happens when you put diesel instead of petrol: what to do
Rarer, less destructive, still needs draining.

## 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

**Is this a garage?**
No. Wrong Fuel Sunderland is mobile. A technician travels to the vehicle wherever it is standing.

**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.

**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.

**How long will I be waiting?**
Arrival depends where you are across SR1 to SR6, DH4 and DH5 and what is already running. You get a realistic window on the call rather than an optimistic one.
