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

Whatever you do, don't switch your engine on, even briefly, to move the car. Stop; leave it off.

Has not been run? Then petrol in a diesel tends to be a simple drain-and-flush job wherever the car has stopped — and nothing settles that more than the next few minutes do.

From now on, step by step, for anywhere around Highfields:

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

In this order, and before everything else:

- The keys out of the ignition. Switching the ignition on can be all it takes to prime the fuel system, while priming pulls petrol out of your tank toward the parts it harms. Keep it off completely.

- A bigger tank of the same mixture is all adding diesel leaves you, because it takes out nothing. So no more diesel.

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

- However short the way, starting it to shift it is the mistake. On a forecourt, roll the vehicle clear of the petrol pump by hand instead, and ask the staff to help.

- Keep the till receipt: the grade and roughly how much are printed on it, and they're what our technicians ask about first.

On the A1(M), under 3 miles from Highfields, the next junction is the location to come off; anywhere, the first safe spot to stop. Don't push on to the services. Then go back to stage one.

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

One answer is what everything after this stage depends on.

If the motor has not run at all:

- Just your tank has petrol in it for now.

- Usually it's emptied and cleaned right where your car stands.

- Stage one matters for exactly this reason: it's the best position to be in.

If it has been started, even for a second:

- Petrol has been drawn from the tank, through the filter and into your lines.

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

- The job grows with the miles — lines purged, filter dealt with, occasionally more.

That line falls there because diesel lubricates the high-pressure fuel pump and the fuel injectors on its way through them — and petrol doesn't.

Petrol resting in a tank damages nothing.

Petrol being pumped is grinding down the parts that move the vehicle.

## Highfields, petrol in a diesel: have these prepared before you call

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

- DN6 7 and the rest of the postcode makes the ideal way to start telling us where you are.

- Name the street — South Street or wherever you have pulled up — or the car park.

- Or the nearest landmark. A car park is quicker to find by what it serves, like the one at Heron Foods.

- Make and model of the vehicle, and the fact it is a diesel.

- Tell us which was put in — petrol or AdBlue — since AdBlue is a different job, with a page of its own for Highfields.

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

- If it's run, how far plus how hard — and if it's run at all.

- Hire or company car? Some agreements need the owner's authorisation for the work, and sorting it before our engineers get there is faster than afterwards.

Next, 0333 366 0103. Not pressing, your car parked at home with nowhere to be? Then  will do too.

## While you wait for a fuel drain in Highfields

During the wait, the damage comes from well-meant help — which is why these matter.

- Stay with the car if it's safe where it is — but if it has stopped somewhere exposed, you come first: away from the traffic, waiting apart from it.

- No one starts it. Not a passer-by being helpful, not to check it is all right, not to roll the vehicle a couple of yards.

- No additives. Two-stroke oil, injector cleaner, anything from the boot — none of it gets that petrol back out.

- Draining it yourself is not the answer: a can of siphoned petrol on a verge is a danger, and your fuel beyond your tank stays where it is anyway.

- Leave your ignition off — your windows and your radio too.

## When our van arrives: your fuel drain, step by step

- Three questions. What was put in, how much, and whether it has run. The replies decide the job, which is why the quote comes after them but not before.

- Next your tank is cleared, so the tainted fuel is taken out.

- The lines are purged. If it ran, that petrol has shifted beyond your tank, and the lines are carrying it.

- The filter is sorted. Cleared, or replaced where the vehicle has a usable one.

- Fresh diesel in, and your system primed.

- We fire it up only after fresh diesel has gone in and primed the system, then confirm that it's running smoothly.

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

It is very uncommon for a vehicle spotted soon to be left with lasting damage, and normal driving starts again right away.

## After the fuel drain: back on the road around Highfields

- Drive normally. There's nothing special to do once it's been started on fresh fuel.

- Keep an eye on the first miles. A warning light, smoke, a rough idle or a flat spot under your throttle tells you to pull over and call us back.

- Your paperwork answers the question a rental company, fleet manager or insurer may ask: what work was carried out. File it.

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