# The Next Steps, in Order: Petrol in a Diesel Car in Church End

Whatever you do, never switch your engine on, even briefly, to move it. Stop; leave the vehicle off.

The next few minutes decide it far more than anything else: petrol in a diesel still unrun normally comes down to draining then flushing, right there.

What follows is the sequence from this point, anywhere around Church End you are.

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

First, the following — in this sequence.

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

- No diesel on top. More fuel in takes away none of the petrol — it only makes you with extra of the same mixture.

- Hazards on. If you're anywhere close to moving traffic, make your car simple to see before you do anything else.

- Off the pump by hand. At a forecourt, get the attendants to help you roll the vehicle away from the pump. Don't fire it up to shift it, however short the distance.

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

Realised on the move? Get off at the next junction if you're on the M1, under 5 miles from Church End, and stop somewhere sensible — not at the services further on. Stage one starts after that.

## Church End fuel drain: has your engine run yet, or not?

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

Not run, not even briefly:

- Only the tank has petrol in it for now.

- Where the vehicle sits is normally where the work happens: a drain, then a flush.

- No place is better, and it is why the first stage counts so much.

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

- Some petrol has left your tank already, gone through your filter, and got into the fuel lines.

- On a bigger run it has reached your high-pressure pump and the injectors.

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

Diesel keeps the high-pressure pump and the fuel injectors oiled as it goes through them. Petrol offers them nothing, and that's why the line is drawn there.

In the tank, left alone, petrol harms nothing.

Petrol being pumped is grinding down the components that move it.

## Before you call about petrol in a diesel in Church End: what we need

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

- Where you have stopped. A postcode starting LU6 1 is the best start.

- Name the road — Ellesmere Close or wherever you have stopped — or the car park.

- Car parks are located most easily by what they serve: tell us the one at Co-op Food, and it is simple.

- Say what the car is — make, model — and confirm it is diesel.

- Petrol or AdBlue? Tell us which. They are different jobs, and AdBlue has a separate Church End page.

- How long the nozzle was in, or the litres from the receipt — whichever gives us how much.

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

- Whose motor it is. Some hire or company agreements want the owner to approve the work, and that is quicker settled before we turn up than after.

Ring 0333 366 0103 then. Email  works too if it can wait, with your car parked at home, going nowhere.

## Church End fuel drain on its way? Whilst you wait

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

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

- No one — however kind — starts it, whether to see if it runs or to shift your car a short way.

- Something from the boot, oil made for two-strokes or injector cleaner: no additive lifts the petrol.

- Siphoning petrol into a can by the roadside is dangerous — and it also leaves whatever fuel has already gone beyond the tank. Don't try a home-made drain.

- Ignition stays off. Even for your radio or the windows.

## The fuel drain, step by step, after the van gets there

- First, three questions: which fuel went in, the amount, and has it run? Those answers decide the job, so our price follows them.

- Draining it's how that blend gets taken from that tank.

- Petrol that has moved beyond your tank sits in your lines once it ran, and the fuel lines are flushed to shift it.

- The fuel filter is sorted. Cleared, or replaced where the car has a serviceable one.

- Clean diesel goes in, then the fuel system is primed.

- The start-up. With clean diesel in and the system primed, it is started and checked to make sure it runs correctly.

Till it runs on clean diesel, we stay with it.

Your car returns to normal use right away, and lasting damage is very unusual when it has been spotted soon.

## Church End, after your fuel drain: back on the road

- Once it has been started on clean fuel, there is nothing special to do: drive normally.

- Give the first miles your attention. Smoke appearing, a warning light coming on, the idle going lumpy or your throttle stumbling: pull over then call us back.

- Hold on to the documents. A hire firm, a fleet manager or an insurer may ask what was done.

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