Woodcock: Petrol in a Diesel Car? Here Is What Happens

Pause, then keep your engine off — not on, and not for a second to move the car. Hasn't been run? Then petrol in a diesel will usually be a straightforward drain-and-flush job wherever your car has stopped — and nothing decides that as much as the next few minutes do. From here on, step by step, for anywhere in Woodcock:

Petrol in a diesel? What to do in minute one

In this sequence, and before everything else:

  • The ignition off, keys out. Turned on, the ignition can prime the system — and priming is what moves petrol out of the tank towards the components it damages.
  • A bigger tank of the same mix is all adding diesel gives you, because it takes out nothing. So no extra diesel.
  • Close to passing traffic? Then the hazard lights go on before anything else, so the vehicle is easy to see.
  • The staff will usually help you roll it clear of the petrol pump. Ask, then roll it by hand — never under the engine, even for a couple of yards.
  • Which fuel, and roughly how much? Your receipt answers both, and that's where our first question starts. Never throw it away.

On the M4, under 25 miles from Woodcock, the next exit is the place to come off; anywhere, the first safe place to stop. Don't push on to the services. Then go back to step one.

Woodcock fuel drain: has the motor run yet, or not?

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

Not run, not even briefly:

  • Just the tank has petrol in it for now.
  • The job is a drain and a flush, normally done where the vehicle is.
  • Being here is the best case — which is the entire point of stage one.

Run at all, even for a second:

  • Some petrol has left the tank by now, gone through the filter, and reached your lines.
  • The high-pressure fuel pump as well as your injectors see it too on a bigger run.
  • The further it went, the bigger the 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 sits where it does. Nothing is damaged by petrol that's only resting in a tank. Move the petrol, though, and it grinds down the very parts that move it.

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

Whether the technician circles or finds you comes down to a little planning.

  • Where you have stopped. A postcode starting BA12 9 is the ideal start.
  • The street or the car park. A road name helps — Rock Lane, or wherever you have stopped.
  • Describe a car park by what it serves — the one outside Waitrose, for example — and it's far quicker to find.
  • That it's a diesel, plus the make and model of the car.
  • What got in. Petrol, or AdBlue. AdBlue is a separate job with its own page for Woodcock, so say which.
  • The amount: the receipt's litres, or else how long you held the nozzle in.
  • If it's run, how far and how heavily — and whether it's run at all.
  • Sort who owns the car before our technicians turn up: some hire and company contracts want the owner to approve the work, and that is faster beforehand.

Phone 0333 366 0103 once you have got that ready — or, if your car is at home, going nowhere, use .

Waiting for a fuel drain in Woodcock: what to do

Stick to these: well-meant help does the harm during the wait.

  • Where the vehicle has stopped decides where you wait. Exposed: away from it, clear of the traffic. Safe: with it. Either way, safety before your car.
  • No one — however kind — starts it, whether to see if it runs or to move the car a short way.
  • Additives stay in the boot. Injector cleaner and two-stroke oil draw none of the petrol out a second time.
  • Siphoning petrol into a can at the kerbside is hazardous — and it still leaves whatever fuel has already gone beyond that tank. Don't try a home-made drain.
  • Not for the radio, not for the windows: the ignition stays off.

Van arrived? The fuel drain, one stage at a time

  • First, three questions: which fuel was put in, the volume, and has it run? Those replies decide this job, so our price follows them.
  • Next your tank is cleared, and the tainted fuel is taken out.
  • Petrol that has moved beyond the tank sits in the fuel lines if it ran, and the lines are purged to clear it.
  • The fuel filter is dealt with. Cleared, or replaced where your car has a usable one.
  • Fresh diesel goes in, and the fuel system is primed.
  • Starting the car. After the fuel system is bled with new diesel, our engineers fire it up and confirm it runs properly.

The vehicle has fresh diesel running through it before we head off. The vehicle goes back to normal use right away, and lasting damage is very uncommon if it has been caught early.

Back on the road in Woodcock after the fuel drain

  • Started on new diesel, it asks nothing unusual of you. Simply drive normally.
  • Pull over and ring us back if anything looks wrong early on — a light on the dash, smoke from the exhaust, an idle that is lumpy, or a throttle with a dead spot.
  • Keep the documents. A hire company, a fleet manager or an insurer may ask what was done.
  • Read the label on the pump next time, not the colour of its handle.
