Wath upon Dearne: Petrol in a Diesel Car? Here Is What Happens

Not for a second, and not to move it: the motor stays off. Pause there. Petrol in a diesel that has not been run is generally a simple drain plus a flush, done where your car sits, and what happens in the next few minutes decides that far more than anything else. Below is the order from this point, wherever in Wath upon Dearne you happen to be.

Petrol in a diesel? What to do in minute one

Work through these first, in this sequence.

  • Keys out of the ignition. Turning your ignition on can be enough to prime the system, and priming draws petrol out of your tank toward the parts it damages. Leave it off altogether.
  • Do not top it up with diesel. Adding diesel takes out nothing. You end up with a fuller tank of the same mixture.
  • Near moving traffic? Then your hazards go on before anything else, so the vehicle is easy to see.
  • By hand, not on the engine: that's how it leaves the petrol pump. Ask the forecourt staff to help you push, whatever the distance.
  • Which fuel, and about how much? Your receipt answers both, and that's where our questions start. Do not throw it away.

On the M1, under 10 miles from Wath upon Dearne, the next exit is the spot to come off; elsewhere, the first sensible location to stop. Don't press on to the services. Then go back to step one.

Has it run yet? The fork in each Wath upon Dearne fuel drain

Everything after this point rests on one answer.

Engine not run at all?

  • The petrol is still in the tank and nowhere else.
  • The job is a simple drain and a flush, usually done where your car stands.
  • Being here is the best case — which is the entire point of stage one.

If the motor has been run, even for a moment:

  • Petrol has been pulled out of that tank, through your filter and into the lines.
  • A longer run takes it all the way to the high-pressure pump and the injectors.
  • The job expands with the miles — lines purged, filter seen to, occasionally more.

Why the line falls there: diesel lubricates the high-pressure pump as well as your injectors as it flows through them, and petrol doesn't. Nothing is damaged by petrol that's only resting in a tank. Move that petrol, though, and it wears the very parts doing the moving.

What to have prepared when you call about petrol in a diesel from Wath upon Dearne

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

  • Your location: a postcode beginning S63 7 serves best.
  • Wherever you have pulled up, the road's name is useful — whether that is Montgomery Square or somewhere else — and so does the name of a car park.
  • Name a car park by what it serves — the one at Tesco Extra, for example — and it's much easier to find.
  • That it's a diesel, along with the make and model of your vehicle.
  • Petrol or AdBlue? Say which. They are separate jobs, and AdBlue has a separate Wath upon Dearne page.
  • The amount: your receipt's litres, or else how long you held the nozzle in.
  • The miles it did, and how heavily, if it ran at all.
  • Whose vehicle it is. Some hire and company agreements want the owner to authorise the work, and that's quicker settled before our engineers arrive than after.

The wait for a Wath upon Dearne fuel drain, and what to do in it

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

  • Safety before the vehicle. If it has stopped somewhere dangerous, get yourself away from the traffic and wait away from it. If it's safe where it sits, wait with it.
  • No one starts it. Not a passer-by being helpful, not to check it is all right, not to roll it a couple of yards.
  • Additives remain in your boot. Injector cleaner and two-stroke oil draw none of the petrol out once more.
  • Siphoning petrol into a can by the roadside is hazardous — and it still leaves whatever fuel has already gone beyond that tank. Don't drain the vehicle yourself.
  • Not for your radio, not for your windows: your ignition remains off.

When our van arrives: the fuel drain, step by step

  • First, three queries: which fuel was put in, the amount, and has it run? Those answers shape this job, so our quote follows them.
  • Out of your tank comes the tainted blend: that tank is emptied.
  • If it ran, the fuel lines are holding petrol that has shifted beyond your tank — so they are purged.
  • Then the fuel filter: swapped where there is a workable one, cleared where there's not.
  • Fresh diesel goes in, then the fuel system is primed.
  • Our engineers fire it up only after new diesel has gone in and bled the fuel system, then make sure that it is running smoothly.

Until it runs on clean diesel, our engineers stay with it. It's very unusual for a car noticed early to be left with long-term damage, and normal use resumes straight away.

Back on the road in Wath upon Dearne after the fuel drain

  • Once it has been started on fresh fuel, there is nothing unusual to do: drive normally.
  • Give the first miles your attention. Smoke appearing, a warning light coming on, your idle going lumpy or your throttle hesitating: pull over then ring us back.
  • The work may matter later with a hire company, an insurer or a fleet manager. Hold on to the paperwork.
  • Read the label on the pump next time, not the colour of the handle.
