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

Not for a moment, and not to move it: your motor remains off. Stop there.

The next few minutes decide it more than anything else: petrol in a diesel that has not run normally amounts to clearing and rinsing, on the spot.

From now on, step by step, for anywhere around Stepney:

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

Before anything else, these — in this sequence.

- Bleeding the fuel system pulls petrol from the tank toward the components it harms, and turning your ignition on can be all it takes to do that. So the keys come out, and the ignition remains off completely.

- A fuller tank of the same mix is all adding diesel leaves you, because it takes out nothing. So no extra diesel.

- Visibility comes before the rest near moving traffic: switch the hazards on, and only then deal with anything else.

- By hand, never under your engine: that is how it comes off the petrol pump. Get the forecourt attendants to help you push, however short the distance.

- Which fuel, and roughly how much? Your receipt replies that, and that is where our first question starts. Don't throw it away.

On the M11, under 10 miles from Stepney, the next junction is the spot to leave the vehicle; anywhere, the first safe place to stop. Don't push on to the services. Then go back to step one.

## The fork in every Stepney fuel drain: has it run yet?

Everything after this stage rests on one answer.

If it has never been started:

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

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

- No position is better, and it is why the first step matters so much.

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

- From your tank, through your filter, into the lines: that's how far the petrol has got.

- Run it further and the petrol reaches the injectors, having gone through the pump first.

- The job expands with the distance — lines purged, filter sorted, occasionally more.

Petrol does not lubricate. Diesel does, protecting the pump and injectors as it flows through, which is why the line sits where it does.

Petrol resting in a tank harms nothing.

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

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

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

- Your location: a postcode starting E1 3 works best.

- A road name is a help: Mile End Road, say, or whichever street you have stopped in. A car park works too.

- What a car park serves is the quickest way to find it, and so say the landmark — such as the one outside China Ark.

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

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

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

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

- The owner may have to approve this work under some hire or company agreements — which is why it's faster to settle whose motor it is before our technicians arrive.

Then phone 0333 366 0103. If it can wait — your car is at home and going nowhere —  works too.

## The wait for a Stepney fuel drain, and what to do in it

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

- Your safety comes before your car. Somewhere exposed? Get away from the traffic and wait away from it. Fine where it is? Stay with it.

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

- None of it gets that petrol back out — not two-stroke oil, not injector cleaner, not something from your boot. So no additives.

- No DIY emptying. Siphoning petrol into a can by the roadside is dangerous, and it leaves the fuel that has already gone beyond the tank.

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

## When the van arrives: your fuel drain, step by step

- Fuel, volume, whether it's run: the replies decide this job, and that's why you get a price after them instead of before.

- Out of that tank comes the polluted mix: the tank is emptied.

- Petrol that has shifted beyond the tank sits in the lines once it ran, and your lines are cleaned to clear it.

- The fuel filter is dealt with. Cleared, or replaced where the car has a workable one.

- Fresh diesel in, and the fuel system primed.

- Starting up. After your system is primed with clean diesel, our technicians start it and check it runs correctly.

Till it runs on fresh diesel, our technicians stay with it.

When it has been spotted quickly, lasting damage is very uncommon, and the vehicle goes back to normal use right away.

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

- Drive normally. There is nothing special to do once it's been started on clean fuel.

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

- The work may come up later with a hire company, an insurer or a fleet manager. Keep your documents.

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