# The Next Steps, in Order: Petrol in a Diesel Car in College Town

Whatever you do, don't switch the engine on, even for a moment, to shift the car. Stop; leave the car off.

Hasn't been run? Then petrol in a diesel will usually be a simple drain-and-flush job wherever your car has stopped — and no other factor settles that as much as these next few minutes do.

Wherever you happen to be in College Town, this is how things go from now.

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

In this sequence, and before anything else:

- Bleeding your fuel system draws petrol from your tank towards the components it damages, and turning your ignition on can be enough to do that. So the keys come out, and your ignition stays off altogether.

- A fuller tank of the same mix is all topping up gives you, since it takes out nothing. So no more diesel.

- Close to moving traffic? Then the hazard lights come on before everything else, and so your car is easy to spot.

- Off the pump by hand. On a forecourt, ask the staff to help you roll the car away from the petrol pump. Do not fire it up to shift it, however short the distance.

- Which fuel, and about how much? The receipt replies both, and that's where our first question starts. Never bin it.

If you were still on the move when you realised, stop somewhere safe instead of pushing on for the services — on the M3, under 3 miles from College Town, that means the next exit. Step one comes next.

## The fork in every College Town fuel drain: has it run yet?

One answer is what everything after this stage rests on.

Motor not run at all?

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

- A drain and flush, on the spot, is usually the whole job.

- This, here, is the best place to be in, and the whole reason step one counts.

Run at all, even for a second:

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

- Run it farther and that petrol reaches your injectors, having passed through your pump first.

- Flushing your lines, the fuel filter dealt with, occasionally more: this job expands as the mileage does.

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

In your tank, left alone, petrol does no harm.

The components that shift it are grinding the moment petrol is being pumped.

## Before you call about petrol in a diesel around College Town: what our engineers need

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

- GU47 0 plus the remainder of the postcode is the ideal way to begin telling us where you are.

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

- Or the nearest landmark. A car park is quicker to find by what it serves, such as the one at Aldi.

- That it's a diesel, along with the make and model of the car.

- What got in. Petrol, or AdBlue. AdBlue is a different job with its own page for College Town, so tell us which.

- How much. Litres from your receipt, or how long the nozzle was in the filler.

- If it has run, how far and how heavily — and if it has run at all.

- The owner may have to authorise this work under some hire or company agreements — so it is quicker to settle whose vehicle it is before our engineers arrive.

Call 0333 366 0103 once you have got that together — or, if your car is at home, going nowhere, use .

## College Town fuel drain on its way? Whilst you wait

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

- Your safety comes before the car. Somewhere unsafe? Get clear of the traffic then wait away from it. Safe where it stands? Wait with it.

- No one — however kind — starts it, whether to see if it runs or to move your car a short way.

- None of it takes the petrol back out — not two-stroke oil, not injector cleaner, not something from the boot. So no additives.

- A home-made drain misses your fuel that has already gone beyond the tank, and siphoning petrol by the road is dangerous besides.

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

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

- Fuel, quantity, whether it has run: the answers set this job, and that's why we give a price after them instead of before.

- Then the tank is emptied, and the contaminated fuel is taken out.

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

- Where the car has a serviceable filter, it is swapped; otherwise, cleared.

- Bleeding your system follows once clean diesel is in.

- Starting the car. When your system is primed with clean diesel, we fire it up and make sure it runs smoothly.

Only once it is running on fresh diesel do our technicians head off.

Your car returns to normal use at once, and lasting damage is very rare if it has been noticed soon.

## Back on the road around College Town after your fuel drain

- Started on fresh diesel, it asks nothing unusual of you. Simply drive normally.

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

- The work may come up later with a hire company, an insurer or a fleet manager. Keep your documents.

- Next time, go by the pump's label rather than the colour of its handle.
