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

Whatever you do, don't switch the motor on, even for a moment, to move the vehicle. Pause; leave it off.

The coming few minutes decide it more than anything else: petrol in a diesel still unrun generally comes down to clearing and purging, right there.

Wherever you happen to be around Defford, this is how things go from now.

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

Go through these in order, before you do anything else.

- Keys out of your ignition. Turning the ignition on can be all it takes to prime your fuel system, while priming draws petrol out of the tank toward the parts it damages. Leave the vehicle off altogether.

- A bigger tank of the same mixture is all adding diesel gives you, since it takes out nothing. So no extra diesel.

- Hazard lights on. If you're anywhere close to moving traffic, make the vehicle easy to see before you do anything else.

- By hand, never under the motor: that is how it leaves the pump. Get the forecourt attendants to help you push, however short the mileage.

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

Realised on the move? Get off at the next exit if you're on the M54, under 15 miles from Defford, and stop somewhere sensible — not at the services farther on. Stage one starts after that.

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

From this stage on, everything hinges on a single answer.

Engine not run at all?

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

- Where your car stands is normally where the work happens: a drain, then a flush.

- Stage one counts for exactly this reason: it is the best place to be in.

Engine run, even for a moment?

- The fuel lines and the fuel filter now carry petrol drawn from your tank.

- A bigger run carries it right through to your high-pressure pump and the fuel injectors.

- The further it went, the bigger this job — the fuel lines, the filter, and now and then more besides.

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

A tank of petrol, left alone, damages nothing.

Petrol being pumped is wearing the components that move the car.

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

Get ready a little, and the van finds you instead of circling.

- Where you have stopped. A postcode beginning WV16 6 is the best start.

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

- Car parks are located more easily by what they serve: say the one outside Sainsbury's, and it is straightforward.

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

- What was put in. Petrol, or AdBlue. AdBlue is a different job with its own page for Defford, and so tell us which.

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

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

- Hire or company car? Some contracts want the owner's authorisation for this work, and getting it before our engineers get there is faster than afterwards.

Next, 0333 366 0103. Not pressing, the car parked at home with nowhere to be? Then  will do as well.

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

Help, however well meant, is what does the damage while you wait. So hold to these.

- Where your car has stopped decides where you wait. Exposed: away from it, away from the traffic. Sensible: with it. Either way, safety before the car.

- Not to roll it a couple of yards, not to check it is all right, not for a passer-by's favour: no one starts it.

- No additives. Two-stroke oil, injector cleaner, anything from the boot — none of it gets the petrol back out.

- Siphoning petrol into a can by the roadside is dangerous — and it still leaves whatever fuel has already gone beyond your tank. Do not drain it yourself.

- Not for your radio, not for the windows: the ignition remains off.

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

- Three questions. What went in, how much, and whether it's run. The replies set the job, which is why the price comes after them and not before.

- Then that tank is emptied, so the tainted fuel comes out.

- If it ran, the fuel lines are carrying petrol that has shifted beyond your tank — so they're rinsed.

- Cleaned, or replaced if the car has a serviceable one: the filter is seen to next.

- Clean diesel in, and the fuel system primed.

- We fire it up only after fresh diesel has gone in and bled the fuel system, then confirm that it's running smoothly.

Only once it's running on clean diesel do we head off.

Lasting damage is very unusual if it has been noticed soon, so the car can go right back to normal driving.

## After the fuel drain: back on the road in Defford

- Drive normally. There is nothing special to do after it has been started on clean fuel.

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

- The work may come up later with a hire firm, an insurer or a fleet manager. Hold on to the documents.

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