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

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

Emptied and rinsed, just where it sits: that is generally all an unrun diesel with petrol in it needs. Whether it stays that straightforward depends on the minutes to come more than on anything else.

Below is the sequence from this point, wherever around Irby you happen to be.

## Petrol in a diesel, motor off — the first minute

In this order, and before anything else:

- Ignition off, keys out. Switched on, the ignition can prime your system — and priming is what moves petrol out of the tank into the components it damages.

- Topping up with diesel sounds like it dilutes the trouble. It doesn't: nothing gets out, and that tank simply holds more of the same.

- Hazards on. If you are at all near moving traffic, make the car easy to see before you do anything else.

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

- Hold on to the till receipt. It shows which fuel went in plus roughly how much, which is the first thing we will ask.

On the M53, under 3 miles from Irby, the next exit is the location to leave the car; elsewhere, the first safe spot to stop. Do not push on to the services. Then go back to stage one.

## Irby fuel drain: has the motor run yet, or not?

What happens next rests on one answer, and just one.

Engine not run at all?

- That petrol is still inside your tank and nowhere else.

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

- Step one counts for exactly this reason: it's the best place to be in.

Engine run, even briefly?

- Petrol has been pulled out of your tank, past the fuel filter and into the lines.

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

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

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

Petrol sitting in a tank damages nothing.

Once it's pumped, petrol starts wearing down whatever moves it.

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

A little preparation is the difference between a technician that finds you and a technician that goes round.

- The best start is a postcode — one starting CH61 3 — for where you are.

- A road name is a help: Thingwall Road, say, or whichever street you've stopped in. A car park does the trick too.

- Describe a car park by what it serves — the one outside Tesco, for example — and it is much easier to find.

- That it's a diesel, plus the make and model of your car.

- Which got in counts: AdBlue is a separate job from petrol, and Irby has a page for it. So tell us.

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

- Whether it has run. And if it has, how far and how heavily.

- The owner may have to authorise the work under some hire or company agreements — which is why it's quicker to settle whose car it is before our technicians get there.

Then phone 0333 366 0103. If it can wait — the car is at home and going nowhere —  does the trick as well.

## While you wait for a fuel drain around Irby

Help, however well meant, is the thing that does the damage while you wait. So stick to these.

- Safety before your car. If it has stopped somewhere unsafe, get yourself clear of the traffic then wait away from it. If it's safe where it stands, wait with it.

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

- Something from your boot, oil meant for two-strokes or injector cleaner: no additive removes that petrol.

- No home-made draining. Siphoning petrol into a can at the kerbside is dangerous, and it leaves the fuel that has already gone beyond that tank.

- Ignition remains off. Even for your radio or your windows.

## The fuel drain, step by step, after the van arrives

- Three queries. What went in, how much, and whether it's run. The replies decide this job, which is why the quote comes after them and not before.

- Your tank is emptied. The tainted blend comes out of that tank.

- Purging your lines comes next, because a motor that ran has petrol past the tank, inside the lines themselves.

- Where the car has a serviceable filter, it's replaced; if not, cleared.

- Bleeding your system follows after fresh diesel is in.

- First start on new diesel. Once priming is finished, the motor is fired up and we confirm that it runs correctly.

We stay until it's running on new diesel.

Your car returns to normal use straight away, and permanent damage is very unusual if it has been noticed quickly.

## Once your fuel drain is done: driving in Irby a second time

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

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

- An insurer, a fleet manager or a hire company may ask what was done, and so keep the paperwork.

- Check the label on the pump next time, not the colour of its handle.
