Petrol in Diesel

The Next Steps, in Order: Petrol in a Diesel Car in Gummows Shop

Not for a second, and not to move it: the motor remains off. Stop there. Petrol in a diesel that has not been run is generally a simple drain plus a flush, done right where the vehicle stands, and what happens in the coming few minutes determines that far more than anything else. From here on, step by step, wherever you are in Gummows Shop:

Engine off: minute one with petrol in a diesel

In this order, all before everything else:

  • The ignition off, keys out. Turned on, your ignition can prime your system — and priming is what moves petrol out of the tank towards the components it harms.
  • Don't top it up with diesel. Adding diesel removes nothing. You are left with a bigger tank of the same mixture.
  • Close to moving traffic? Then your hazards go on before anything else, so the car is simple to see.
  • Off the petrol pump by hand. On a forecourt, ask the staff to help you push the car clear of the pump. Don't start the vehicle to move it, however short the way.
  • The first thing you will be asked is which fuel you put in and about how much — and your receipt shows both. Hold on to it.

Still driving when you noticed? Come off the M5 at the next junction if that's where you are, over 50 miles from Gummows Shop, and pull over somewhere safe rather than pushing on to the services. Then begin at step one.

Has it run yet? The fork in every Gummows Shop fuel drain

Everything after this point rests on one answer.

If your motor hasn't run at all:

  • Just your tank has petrol in it for now.
  • The work is a drain and a flush, usually done where the car stands.
  • Stage one matters for exactly this reason: it's the best spot to be in.

If it has been started, even for a second:

  • Your lines and the fuel filter now carry petrol drawn from that tank.
  • On a bigger run it has reached your high-pressure pump and the injectors.
  • The farther it went, the bigger the job — the fuel lines, the fuel filter, and now and then more besides.

Why the line falls there: diesel protects the high-pressure fuel pump as well as the injectors as it flows through them, and petrol doesn't. Petrol sitting in a tank damages nothing. Petrol being pumped is wearing the components that shift the car.

What to have prepared when you call about petrol in a diesel from Gummows Shop

Whether the van goes round or finds you depends on a little preparation.

  • Where you have stopped. A postcode starting TR8 4 is the best start.
  • A road name helps: A3058, say, or whatever street you've stopped in. A car park works too.
  • Or the landmark. A car park is quicker to find by what it serves, such as the one outside Hendra Supermarket.
  • The vehicle. Make, model, and that it's a diesel.
  • What went in. Petrol, or AdBlue. AdBlue is a different job with its own page for Gummows Shop, so say which.
  • How long the nozzle was in, or the litres on the receipt — either tells us how much.
  • Has it run? If so, say how far it got, and how it was driven.
  • The owner may have to authorise this work under some hire or company agreements — which is why it is faster to settle whose motor it is before our technicians arrive.

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

While you wait for a fuel drain around Gummows Shop

In the wait, the damage comes from well-intended help — so these count.

  • Wait with your car if it's safe where it is — but if it has stopped somewhere dangerous, you come first: away from the traffic, waiting apart from it.
  • Not to roll it a couple of yards, not to check it is all right, not as a passer-by's favour: nobody starts it.
  • Additives stay in the boot. Injector cleaner and two-stroke oil take none of the petrol out again.
  • Draining it yourself is not the answer: a can of siphoned petrol on a verge is a danger, and the fuel beyond the tank remains put anyway.
  • The ignition remains off. Even for the radio or the windows.

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

  • Three questions. What got in, how much, and if it has run. Those answers shape this job, which is why the quote comes after them but not before.
  • Draining it's how the mixture gets taken out of that tank.
  • The lines are flushed. If it ran, the petrol has shifted beyond that tank, and the lines are holding it.
  • Cleared, or changed if the car has a workable one: the filter is sorted next.
  • Fresh diesel goes in, and the system is primed.
  • The start. With clean diesel in and your system bled, it's started and checked to be sure it runs correctly.

Until it runs on fresh diesel, our technicians remain with it. It's very uncommon for a vehicle caught soon to be left with permanent damage, and normal driving resumes right away.

Gummows Shop, after the fuel drain: back on the road

  • After it has been started on fresh fuel, there is 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 call us a second time.
  • An insurer, a fleet manager or a hire company may ask what was carried out, and so keep the paperwork.
  • Next time, check the pump. The label, not the colour of its handle.
