# Petrol in a Diesel Car in Hamfield: What Happens Now

Not for a moment, and not to move it: the motor stays off. Stop there.

The next few minutes settle it far more than anything else: petrol in a diesel that has not run usually amounts to clearing and flushing, right there.

Here is the sequence of things from here, wherever you're around Hamfield.

## Minute one: petrol in a diesel, engine off

Work through the following in order, first.

- The ignition off, keys out. Turned on, your ignition can prime your system — and priming is what moves petrol out of the tank towards the parts it damages.

- A bigger tank of the same mix is all adding diesel leaves you, because it removes nothing. So no extra diesel.

- Being seen comes first beside moving traffic: switch your hazards on, and only then deal with anything else.

- However short the distance, starting it to move it is the thing to avoid. On a forecourt, roll the vehicle away from the pump by hand instead, then ask the staff to help.

- The first question we will ask is which fuel went in and roughly how much — and the till receipt says both. Keep it.

If you were still driving when you realised, stop somewhere safe rather than pushing on for the services — on the M5, under 10 miles from Hamfield, that means the next junction. Stage one follows.

## Hamfield fuel drain: has the engine run yet, or not?

What happens after this rests on one answer, and only one.

Motor never run at all?

- Just the tank has petrol in it for now.

- Draining and flushing, on the spot, is normally all of it.

- Being here is the best case — which is the entire point of stage one.

If your engine has been run, even briefly:

- Petrol has been pulled out of that tank, through the fuel filter then into your lines.

- Run it further and the petrol gets to the fuel injectors, having gone through your fuel pump first.

- Flushing your lines, the fuel filter dealt with, and sometimes more: this job grows as the miles does.

The reason the line falls there: diesel protects your high-pressure pump and your injectors as it flows through them, and petrol does not.

Petrol resting in a tank damages nothing.

Petrol being pumped is wearing the components that shift it.

## Calling about petrol in a diesel from Hamfield: what to have ready

A van that circles versus a technician that finds you: a little preparation is what separates them.

- BS27 3 plus the remainder of the postcode makes the ideal way to begin telling us where you are.

- The street or the car park. A road name is a help — Purdie Close, or wherever you have pulled up.

- What a car park serves is the easiest way to find it, and so say the landmark — like the one at Sainsbury's.

- Say what your vehicle is — make, model — and confirm it is diesel.

- Petrol or AdBlue? Tell us which. They are different jobs, and AdBlue has its own Hamfield page.

- The quantity: the receipt's litres, or else how long you held the nozzle in.

- The mileage it covered, and how hard, if it ran at all.

- Whose vehicle it is. Some hire or company contracts want the owner to authorise the work, and that is quicker settled before we turn up than after.

Ring 0333 366 0103 once you have got that together — or, if the vehicle is at home, going nowhere, use .

## The wait for a Hamfield fuel drain, and what to do in it

During the wait, the damage comes from well-meant help — so these matter.

- Safety before your car. If it has stopped somewhere unsafe, get yourself away from the traffic then wait away from it. If it is safe where it is, wait with it.

- Nobody — however kind — starts it, whether to see if it runs or to shift the vehicle a short way.

- Additives remain in the boot. Injector cleaner and two-stroke oil take none of the petrol out once more.

- Siphoning petrol into a can by the roadside is hazardous — and it also leaves whatever fuel has already gone beyond that tank. Do not try a home-made drain.

- Ignition remains off. Even for your radio or the windows.

## Van arrived? Your fuel drain, one step at a time

- The quote comes after three questions, not before them — what went in, how much, and whether it's run — since the answers shape the job.

- Draining it is how that blend gets taken from your tank.

- Cleaning the lines comes next, since a motor that ran has petrol past your tank, in your lines themselves.

- Where the vehicle has a workable filter, it's changed; if not, cleared.

- Clean diesel goes in, then your system is primed.

- Starting the car. After the system is primed with fresh diesel, our technicians fire it up and confirm it runs smoothly.

Until it runs on fresh diesel, our engineers remain with it.

Long-term damage is very rare when it has been spotted soon, so the car can go straight back to normal driving.

## Hamfield, after the fuel drain: back on the road

- After it has been started on fresh fuel, there is nothing unusual to do: drive normally.

- The first miles are the test. A warning lamp, exhaust smoke, a rough idle or a hesitant throttle is your cue to stop then call us once more.

- Your documents covers the question a rental company, fleet manager or insurer may ask: what work was carried out. Keep it.

- Next time, read the pump. The label, not the colour of its handle.
