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

Pause, then leave your engine off — not on, and not for a moment to shift the car.

Petrol in a diesel that has not been run is generally a drain plus a flush, done where the vehicle sits, and what you do in the coming few minutes settles that more than anything else.

Anywhere you are in Northfield, this is the order things run from here.

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

In this sequence, and before everything else:

- Take your keys out. Even the ignition by itself can prime the system, drawing petrol out of the tank to precisely the parts it harms, and so leave it alone entirely.

- Do not top it up with diesel. Adding diesel removes nothing. You are left with a bigger tank of the same mix.

- Make your car easy to see before anything else — hazard lights on — if there's moving traffic anywhere close to you.

- The staff will normally help you push it away from the petrol pump. Let them, then roll it by hand — never on the motor, even for a couple of yards.

- The first thing you will be asked is which fuel went in and about how much — and your receipt shows both. Keep it.

Realised on the move? Get off at the next junction if you are on the M8, under 10 miles from Northfield, and pull over somewhere safe — not at the services farther on. Step one starts after that.

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

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

Not run, not even once:

- The petrol sits in your tank, and only there.

- Normally it is drained and rinsed right where the vehicle stands.

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

Engine run, even for a moment?

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

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

- The job expands with the mileage — lines purged, filter dealt with, sometimes more.

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

Nothing is harmed by petrol that's only waiting in a tank.

As soon as it's pumped, petrol begins wearing down whatever moves it.

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

A technician that circles versus a technician that finds you: a little preparation is what separates them.

- The best place to start is a postcode — one starting EH8 7 — for where you are.

- Give the street — Northfield Square or wherever you have pulled up — or the car park.

- Car parks are found more easily by what they serve: say the one at Morrisons, and it is simple.

- That it's a diesel, along with the make and model of your car.

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

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

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

- Whose vehicle it is. Some hire and company agreements want the owner to approve the work, and that's easier settled before our technicians arrive than after.

Next, 0333 366 0103. Not pressing, the vehicle parked at home with nowhere to be? Then  works too.

## While you wait for a fuel drain around Northfield

In the wait, the harm comes from well-meant help — so these matter.

- Where your car has stopped settles where you wait. Exposed: away from it, clear of the traffic. Sensible: with it. Either way, safety ahead of the car.

- A kind passer-by does not crank it. Nor does anyone checking it still does the trick, or rolling it a couple of yards.

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

- No home-made clearing. Siphoning petrol into a can at the kerbside is dangerous, and it leaves the fuel that has by now gone beyond the tank.

- The ignition remains off. Even for the radio or the windows.

## Step by step: the fuel drain when our van gets there

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

- Next that tank is cleared, and the contaminated fuel comes out.

- Petrol that has moved beyond the tank sits in the lines if it ran, and the lines are purged to shift it.

- Cleaned, or replaced if your car has a workable one: your filter is dealt with next.

- The fuel system is primed with clean diesel.

- We start the car only after fresh diesel has gone in and primed your system, then make sure that it is running correctly.

Our engineers wait until it is running on new diesel.

Permanent damage is very uncommon if it has been spotted soon, so the vehicle can go straight back to normal use.

## Back on the road around Northfield after the fuel drain

- Started on new diesel, it needs nothing special of you. Simply drive normally.

- Keep an eye on the first miles. A warning light, smoke, a rough idle or a flat spot under the throttle means pull over and ring us back.

- An insurer, a fleet manager or a hire firm may ask what was done, and so hold on to your documents.

- Next time, trust the pump's label instead of the colour of its handle.
