# What Happens Now: Petrol in a Diesel Car in Harts Hill

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

The coming few minutes settle it far more than anything else: petrol in a diesel that has not run usually comes down to draining and rinsing, right there.

What follows is the sequence from this point, wherever around Harts Hill you are.

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

Work through the following first, in this order.

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

- Topping up with diesel seems like it dilutes the issue. It doesn't: nothing gets out, and your tank just holds more of the same.

- Visibility comes before the rest beside moving traffic: put your hazards on, and only then think about anything else.

- However short the way, starting it to shift it is the thing to avoid. On a forecourt, push the vehicle clear of the petrol pump by hand instead, then ask the attendants to help.

- The first thing we will ask is which fuel went in and about how much — and the till receipt shows both. Hold on to it.

If you were still driving when you noticed, stop somewhere safe instead of pushing on for the services — on the M5, under 5 miles from Harts Hill, that means the next exit. Step one follows.

## Has it run yet? The fork in each Harts Hill fuel drain

One answer is what everything after this stage rests on.

Engine not run at all?

- Nowhere but that tank: that's where that petrol yet is.

- Usually it's emptied and rinsed just where the vehicle is.

- This is the best position to be in, and the reason stage one matters.

Run at all, however briefly:

- Petrol has been drawn from your tank, through the filter then into the lines.

- On a bigger run it has got to your high-pressure pump as well as your injectors.

- The farther it went, the bigger this job — the lines, the fuel filter, and sometimes more besides.

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

Nothing is harmed by petrol that's just sitting in a tank.

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

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

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

- DY5 1 and the rest of the postcode is the best way to begin telling us where you are.

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

- Or the landmark. A car park is quicker to find by what it serves, like the one at Aldi.

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

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

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

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

- Hire or company car? Some contracts want the owner's authorisation for the work, and getting it before we arrive is quicker than after.

Then call 0333 366 0103. If it can wait — the vehicle is at home with going nowhere —  works too.

## Harts Hill fuel drain on its way? While you wait

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

- Your safety comes before your car. Somewhere unsafe? Get away from the traffic then wait away from it. Fine where it sits? Wait with it.

- 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.

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

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

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

## The fuel drain, step by step, once our van gets there

- Our price comes after three queries, not before them — what went in, how much, and if it has run — because the answers set the job.

- Draining it is how that mixture gets taken from your tank.

- If it ran, your lines are holding petrol that has moved beyond the tank — so they're flushed.

- Cleared, or replaced if the car has a workable one: the filter is sorted next.

- Your system is primed with clean diesel.

- We start the engine only after clean diesel has gone in and bled the system, then make sure that it is running correctly.

Only once it's running on fresh diesel do our technicians head off.

If it has been caught early, lasting damage is very unusual, and your car returns to normal driving right away.

## After your fuel drain: back on the road around Harts Hill

- After it's been started on fresh fuel, there's nothing special to do: drive normally.

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

- An insurer, a fleet manager or a hire company may ask what was carried out, and so keep the documents.

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