# What Happens Now: Petrol in a Diesel Car in Enfield Wash

Whatever you do, don't switch your engine on, even briefly, to shift the car. Pause; leave the vehicle off.

Drained and purged, right where it sits: that's generally all an unrun diesel with petrol in it takes. Whether it stays that simple depends on the minutes ahead far more than on everything else.

Wherever you are in Enfield Wash, this is the order things go from now.

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

Before anything else, the following — following this order.

- Keys out of the ignition. Turning your ignition on can be all it takes to prime your fuel system, while priming draws petrol out of your tank toward the components it harms. Keep it off completely.

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

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

- The staff will usually help you push it away from the petrol pump. Ask, then roll it by hand — not on the motor, even for a couple of yards.

- The first thing we will ask is which fuel went in and roughly how much — and the receipt shows both. Keep it.

On the Holmesdale Tunnel, under 3 miles from Enfield Wash, the next exit is the location to leave it; elsewhere, the first safe spot to stop. Don't press on to the services. Then go back to step one.

## Has it run yet? The fork in every Enfield Wash fuel drain

What comes next turns on one answer, and only one.

Motor never run at all?

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

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

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

If your engine has run, even for a moment:

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

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

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

Why the line falls there: diesel lubricates the high-pressure pump and your injectors as it passes through them, and petrol does not.

In your tank, sitting still, petrol harms nothing.

Pump the petrol, though, and it grinds down the very parts doing the moving.

## What to have ready when you call about petrol in a diesel from Enfield Wash

A little planning is the difference between a technician that finds you and a van that circles.

- Where you have stopped. A postcode beginning EN3 5 is the best place to start.

- Give the street — Bell Lane or wherever you have pulled up — or the car park.

- What a car park serves is the easiest way to find it, so say the landmark — like the one outside Enfield Food Centre.

- That it is a diesel, plus the make and model of your vehicle.

- What was put in. Petrol, or AdBlue. AdBlue is a separate job with its own page for Enfield Wash, so say which.

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

- If it's run, how far and how hard — and if it has run at all.

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

Then ring 0333 366 0103. If it can wait — your car is at home and going nowhere —  does the trick too.

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

The wait is where kindly meant help does the damage. Stick to these.

- Safety before your car. If it has stopped somewhere dangerous, get yourself away from the traffic then wait away from it. If it is safe where it is, wait with it.

- A kind passer-by doesn't crank it. Nor does anyone wanting to check it still works, or rolling it a few yards.

- No additives. Two-stroke oil, injector cleaner, something from your boot — none of it takes that petrol back out.

- Siphoning petrol into a can by the kerbside is dangerous — and it still leaves whatever fuel has already gone beyond your tank. Don't drain the vehicle yourself.

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

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

- First, three queries: which fuel got in, the amount, and has it run? Those answers set the job, so our quote follows them.

- Out of the tank comes the polluted blend: your tank is cleared.

- The lines are purged. If it ran, that petrol has shifted beyond that tank, and your lines are carrying it.

- Cleaned, or changed if the car has a serviceable one: your filter is dealt with next.

- Clean diesel in, and your system primed.

- The start-up. With new diesel in and your system bled, it is started and tested to make sure it runs properly.

Till it runs on clean diesel, our technicians remain with it.

If it has been noticed early, long-term damage is very rare, and the vehicle goes back to normal use at once.

## Enfield Wash, after your fuel drain: back on the road

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

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

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

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