# Portfields: Petrol in a Diesel Car? Here Is What Happens

Whatever you do, never switch your engine on, even briefly, to shift the car. Pause; leave the vehicle off.

Cleared and flushed, right where it is: that is normally all an unrun diesel with petrol in it takes. Whether it remains that simple depends on the minutes to come more than on everything else.

Here's the sequence of things from now, wherever you are around Portfields.

## Petrol in a diesel? What to do in minute one

Go through these in order, before you do anything else.

- Priming your fuel system pulls petrol from the tank towards the parts it harms, and turning your ignition on can be all it takes to do that. So the keys get taken out, and your ignition stays off altogether.

- Don't top it up with diesel. Adding diesel takes out nothing. You are left with a bigger tank of the same mixture.

- Near moving traffic? Then the hazard lights go on before everything else, and so the car is simple to see.

- The attendants will normally help you roll it away from the petrol pump. Ask, and roll it by hand — not under the motor, even for a couple of yards.

- Keep your receipt. It shows which fuel got in and roughly how much, which is the first thing we'll ask.

Still on the move when you noticed? Come off the M50 at the next junction if that is where you are, under 15 miles from Portfields, and stop somewhere safe rather than pressing on to the services. Then begin at stage one.

## Has it run yet? The fork in each Portfields fuel drain

Everything after this stage depends on one answer.

Not run, not even once:

- Nowhere but the tank: that is where the petrol yet is.

- The job is a simple drain and a flush, normally done where the car is.

- This is the best case — which is the whole point of step one.

If it's been started, even for a second:

- The lines and the filter now carry petrol drawn from the tank.

- A longer run takes it right through to the high-pressure pump and the fuel injectors.

- Flushing the lines, the filter seen to, occasionally more: this job grows as the miles does.

Petrol doesn't lubricate. Diesel does, oiling the pump and injectors as it flows through, which is why the line falls where it does.

Petrol sitting in a tank harms nothing.

Pump the petrol, though, and it grinds down the very parts that move it.

## What to have ready when you call about petrol in a diesel from Portfields

A little preparation is the difference between a van that finds you and a technician that circles.

- Where you are. A postcode starting HR1 2 is the ideal start.

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

- Name a car park by what it serves — the one outside Asian Grocery Hub, for example — and it's far quicker to find.

- The vehicle. Make, model, plus that it's a diesel.

- Petrol or AdBlue? Tell us which. They are separate jobs, and AdBlue has a separate Portfields page.

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

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

- The owner may have to approve the work under some hire or company agreements — which is why it is faster to settle whose motor it is before our technicians get there.

Ring 0333 366 0103 then. Email  is fine as well if it can wait, with the vehicle parked at home, going nowhere.

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

The wait is where kindly meant help does the damage. Hold to these.

- Where the car has stopped decides where you wait. Exposed: away from it, away from the traffic. Sensible: with it. Either way, safety ahead of the car.

- No one starts it. Not a passer-by being kind, not to check it is all right, not to roll it a few yards.

- Something from the boot, oil made for two-strokes or injector cleaner: no additive lifts the petrol.

- Siphoning petrol into a can by the roadside is risky — and it still leaves whatever fuel has already gone beyond that tank. Don't drain the car yourself.

- Not for the radio, not for the windows: your ignition remains off.

## Step by step: your fuel drain when the van arrives

- Three questions. What was put in, how much, and if it's run. Those replies set the job, which is why our quote comes after them and not before.

- Then that tank is cleared, and the contaminated fuel comes out.

- Your lines are cleaned. If it ran, that petrol has moved beyond the tank, and the lines are holding it.

- Then the filter: changed where there's a usable one, cleared where there's not.

- Clean diesel in, and your system primed.

- We fire it up only after clean diesel has gone in and bled the system, then confirm that it is running properly.

Only when it is running on fresh diesel do our engineers head off.

Permanent damage is very rare when it has been noticed soon, so your car can go straight back to normal driving.

## Once your fuel drain is done: driving in Portfields again

- Nothing unusual is needed after a start with fresh diesel — usual driving will do.

- The first miles are the test. A warning lamp, exhaust smoke, a rough idle or a hesitant throttle is your signal to stop then ring us again.

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

- Check the label on the petrol pump next time, not the colour of the handle.
