# What Happens Now: Petrol in a Diesel Car in Carrick Knowe

Stop. Engine off. Keep the car that way — no second on, no shifting it at all.

Has not been run? Then petrol in a diesel tends to be a straightforward drain-and-flush job wherever your car has stopped — and no other factor decides that as much as the next few minutes do.

Here is the order of things from now, wherever you're around Carrick Knowe.

## Engine off: minute one with petrol in a diesel

In this order, all before everything else:

- Priming the fuel system pulls petrol from the tank towards the components it damages, and turning your ignition on can be enough to do that. So your keys get taken out, and your ignition stays off completely.

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

- Close to moving traffic? Then the hazards come on before anything else, so the vehicle is easy to see.

- By hand, not under the motor: that's how it leaves the pump. Ask the forecourt staff to help you roll, whatever the distance.

- Hold on to your receipt: the fuel and roughly how much are printed on it, and they're what our engineers ask for first.

Still on the move when you realised? Come off the M8 at the next junction if that is where you are, under 3 miles from Carrick Knowe, and stop somewhere safe rather than pressing on to the services. Then start at stage one.

## Carrick Knowe fuel drain: has your motor run yet, or not?

From this stage on, everything comes down to a single answer.

Not run, not even briefly:

- Just your tank has petrol in it for now.

- The job is a drain and a flush, usually done where the car stands.

- This is as good as it gets — which is the entire point of stage one.

Engine run, even briefly?

- Some petrol has left your tank by now, passed through the fuel filter, and got into the fuel lines.

- On a bigger run it has reached your high-pressure pump as well as the fuel injectors.

- Miles is what makes it a larger job: the lines flushed, a filter seen to, and at times further work.

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

Petrol resting in a tank harms nothing.

Petrol being pumped is wearing the parts that shift the vehicle.

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

Get ready a little, and the van finds you rather than circling.

- The best place to start is a postcode — one starting EH12 7 — for where you have stopped.

- Wherever you have parked, the road's name is useful — whether that's Lampacre Road or somewhere else — and so does the name of a car park.

- Describe a car park by what it serves — the one at Co-op Food, for instance — and it is much quicker to find.

- Make and model of the car, and the fact it's a diesel.

- What was put in. Petrol, or AdBlue. AdBlue is a separate job with its own page for Carrick Knowe, and so say which.

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

- Has it run? If so, tell us how far it got, and how it was driven.

- Whose vehicle it is. Some hire and company agreements want the owner to authorise this work, and that is easier settled before our technicians get there than after.

Phone 0333 366 0103 once you've got that ready — or, if the vehicle is at home, going nowhere, use .

## Carrick Knowe fuel drain on its way? Whilst you wait

Stick to these: kindly meant help does the damage during the wait.

- Your safety comes before the car. Somewhere dangerous? Get away from the traffic then wait away from it. Safe where it stands? Stay with it.

- Nobody — however helpful — starts it, whether to see if it runs or to move your car a short way.

- No additives. Two-stroke oil, injector cleaner, anything from the boot — none of it takes the 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 that tank stays where it is all the same.

- Keep the ignition off — your windows and the radio too.

## Step by step: your fuel drain when the van gets there

- First, three queries: which fuel was put in, the quantity, and has it run? Those replies set the job, and so the quote follows them.

- Out of that tank comes the contaminated mixture: the tank is cleared.

- Your lines are purged. If it ran, the petrol has shifted beyond that tank, and the fuel lines are holding it.

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

- Priming comes after clean diesel is in.

- The start. With fresh diesel in and your system primed, it's started and checked to be sure it runs properly.

Only once it's running on new diesel do we leave.

It is very unusual for a vehicle caught quickly to be left with permanent damage, and normal use resumes straight away.

## After your fuel drain: back on the road around Carrick Knowe

- Nothing special is needed after a start with clean diesel — normal driving will do.

- Pull over and ring us back if anything seems wrong early on — a light on your dash, smoke from your exhaust, an idle that runs rough, or a throttle with a dead spot.

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

- The handle's colour is not the thing to go by next time — the label on the petrol pump is.
