# Petrol in a Diesel Car in Church Crookham: What Happens Now

Whatever you do, never switch your motor on, even for a moment, to move the vehicle. Pause; leave the vehicle off.

Petrol in a diesel that hasn't been run is normally a drain plus a flush, done where the car sits, and what you do in the next few minutes decides that far more than anything else.

Here is the order of things from now, anywhere you are in Church Crookham.

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

Go through these in sequence, first.

- Keys out of the ignition. Switching the ignition on can be enough to prime the system, and priming pulls petrol out of your tank toward the parts it harms. Leave the car off completely.

- Topping up with diesel sounds like it dilutes the issue. It does not: nothing gets out, and the tank just carries more of the same.

- Get the vehicle easy to see before anything else — hazards on — if there is traffic going past anywhere near you.

- By hand, never on your engine: that's how it comes off the pump. Ask the forecourt staff to help you roll, however short the distance.

- Keep the receipt. It says which fuel went in and about how much, which is the first thing we'll ask.

Still on the move when you noticed? Come off the M3 at the next exit if that is where you are, under 3 miles from Church Crookham, and pull over somewhere safe rather than pressing on to the services. Then begin at step one.

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

What comes after this rests on one answer, and only one.

Motor never run at all?

- Just that tank has petrol in it for now.

- A drain and flush, on the spot, is usually all of it.

- No spot is better, and it is why the first step counts so much.

If the motor has been run, even for a moment:

- Out of the tank, through the filter, into your lines: that is how far that petrol has got.

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

- The job grows with the miles — lines rinsed, filter sorted, sometimes more.

Petrol does not lubricate. Diesel does, oiling the high-pressure pump and injectors as it passes through, which is why the line falls where it does.

Petrol sitting in a tank harms nothing.

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

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

A technician that circles against a technician that finds you: a little preparation is the difference.

- GU52 8 and the remainder of the postcode is the best way to begin telling us where you are.

- Wherever you have pulled up, the road's name helps — whether that is Sandy Lane or somewhere else — and so does the name of a car park.

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

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

- Say which went in — petrol or AdBlue — because AdBlue is a different job, with a page of its own for Church Crookham.

- About how much — in litres from the receipt, or by how long the nozzle stayed in.

- Has it run? If so, say how far it went, and how it was driven.

- Hire or company car? Some contracts want the owner's go-ahead for this work, and getting it before our technicians arrive is quicker than afterwards.

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

## While you wait for a fuel drain in Church Crookham

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

- Stay with the car if it is safe where it is — but if it has stopped somewhere dangerous, 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 the car a couple of yards.

- Anything from your boot, oil made for two-strokes or injector cleaner: no additive removes the petrol.

- Emptying it yourself is out: a can of siphoned petrol on a verge is a danger, and the fuel beyond the tank stays put all the same.

- Even the radio or the windows are not worth switching your ignition on for.

## When the van gets there: the fuel drain, step by step

- The price comes after three queries, not before them — what got in, how much, and whether it has run — because the replies decide the job.

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

- Petrol that has shifted beyond that tank sits in your lines if it ran, and the lines are rinsed to shift it.

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

- The fuel system is primed on clean diesel.

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

The vehicle has clean diesel running through it before our engineers go.

When it has been noticed soon, lasting damage is very unusual, and the car returns to normal driving right away.

## After your fuel drain: back on the road in Church Crookham

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

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

- An insurer, a fleet manager or a hire company may ask what was carried out, and so hold on to the paperwork.

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