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

Stop, and keep the motor off — not on, and not for a second to move the car.

The next few minutes decide it more than anything else: petrol in a diesel still unrun usually amounts to clearing then rinsing, on the spot.

What follows is the sequence from this point, anywhere in Moy you happen to be.

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

Work through these in order, first.

- Pull your keys out. Even the ignition by itself can prime the fuel system, pulling petrol out of your tank to exactly the components it damages, so keep the vehicle alone entirely.

- Do not top it up with diesel. Adding diesel takes out nothing. You are left with a bigger tank of the same mix.

- Get your car simple to see first — hazards on — if there's moving traffic anywhere near you.

- Off the petrol pump by hand. On a forecourt, ask the staff to help you roll it away from the pump. Don't crank it to move it, however short the way.

- Hold on to your receipt: the grade and the rough amount are printed on it, and they are what our engineers ask for first.

If you were still on the move when you noticed, pull over somewhere safe rather than pushing on for the services — on the M77, over 50 miles from Moy, that means the next junction. Stage one follows.

## Every Moy fuel drain starts here: has the engine run?

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

If the engine hasn't run at all:

- The petrol is still in your tank and nowhere else.

- Where the car sits is normally where this work is done: a drain, then a flush.

- This is the best spot to be in, and the reason stage one counts.

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

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

- The high-pressure pump as well as the injectors see it too on a longer run.

- The job grows with the distance — lines rinsed, filter sorted, occasionally more.

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

A tank of petrol, left alone, damages nothing.

Pump that petrol, though, and it wears the very parts doing the moving.

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

A technician that circles against a van that finds you: a little planning is what separates them.

- The best start is a postcode — one starting BT71 7 — for where you have stopped.

- Give the road — Chalet Road or wherever you have pulled up — or the car park.

- What a car park serves is the quickest way to find it, and so say the landmark — like the one at the local shops.

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

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

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

- Has it run? If so, say how far it got, and the way it was driven.

- Settle who owns the car before our technicians turn up: some hire and company agreements want the owner to authorise this work, and doing it faster beforehand.

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

## Moy fuel drain on its way? While you wait

The wait is where well-intended help does the damage. Hold to these.

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

- Nobody starts it. Not a passer-by being helpful, not to check it is all right, not to roll it a few yards.

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

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

- The ignition remains off. Even for your radio or the windows.

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

- Our quote comes after three questions, not before them — what was put in, how much, and whether it's run — because the answers set the job.

- Emptying it's how the mixture gets taken out of the tank.

- The fuel lines are flushed. If it ran, that petrol has moved beyond that tank, and your lines are holding it.

- Cleared, or changed if the vehicle has a serviceable one: the fuel filter is seen to next.

- Priming follows after fresh diesel is in.

- The start. With clean diesel in and the fuel system primed, it's fired up and checked to make sure it runs smoothly.

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

The vehicle returns to normal use right away, and permanent damage is very unusual when it has been caught quickly.

## Back on the road in Moy after the fuel drain

- Once it's been started on clean fuel, there is nothing unusual to do: drive normally.

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

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

- The handle's colour isn't the guide to go by next time — the label on the petrol pump is.
