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

Pause, and leave your motor off — not on, and not for a moment to move it. The next few minutes settle it far more than anything else: petrol in a diesel that has not run usually amounts to draining then rinsing, right there. Below is the sequence from here, wherever in Shirenewton you happen to be.

Minute one: petrol in a diesel, motor off

Work through these in sequence, before you do anything else.

  • Pull your keys out. Even your ignition on its own can prime your fuel system, drawing petrol out of your tank to precisely the parts it damages, and so leave the vehicle alone completely.
  • Don't top it up with diesel. Adding diesel takes out nothing. You end up with a fuller tank of the same mix.
  • Close to passing traffic? Then the hazards come on before everything else, and so your car is simple to see.
  • However short the way, starting it to shift it is the thing to avoid. At a forecourt, push it away from the petrol pump by hand instead, and ask the staff to help.
  • The first thing we will ask is which fuel you put in and roughly how much — and the receipt says both. Keep it.

On the M48, under 3 miles from Shirenewton, the next junction is the spot to come off; elsewhere, the first sensible place to stop. Do not push on to the services. Then go back to stage one.

The fork in every Shirenewton fuel drain: has it run yet?

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

If your motor has not run at all:

  • Nowhere but that tank: that is where that petrol yet is.
  • Normally it's emptied and purged right where the vehicle is.
  • No position is better, and it is why the first stage counts so much.

Run at all, even for a second:

  • From that tank, past the filter, into the fuel lines: that is how far the petrol has travelled.
  • A bigger run carries it right through to the high-pressure fuel pump and your injectors.
  • The farther it went, the bigger the job — the lines, the filter, and now and then more besides.

Diesel keeps the high-pressure pump and the injectors lubricated as it goes through them. Petrol gives them nothing, and that is why the line is drawn there. A tank of petrol, left alone, hurts nothing. As soon as it is pumped, petrol starts wearing down whatever moves it.

What to have ready when you call about petrol in a diesel from Shirenewton

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

  • The best start is a postcode — one beginning NP16 6 — for where you have stopped.
  • Wherever you have pulled up, the road's name helps — whether that's Blacksmiths Lane or somewhere else — and so does the name of a car park.
  • Or the nearest landmark. A car park is quicker to find by what it serves, such as the one outside M&S Foodhall.
  • The make and model of your car, and the fact it's a diesel.
  • Petrol or AdBlue? Tell us which. They are different jobs, and AdBlue has its own Shirenewton page.
  • How long the nozzle was in, or the litres on the receipt — whichever tells us how much.
  • If it has run, how far and how hard — and whether it's run at all.
  • Hire or company car? Some agreements want the owner's go-ahead for the work, and getting it before we get there is quicker than afterwards.

Next, 0333 366 0103. Not pressing, the car parked at home with nowhere to be? Then works as well.

While you wait for a fuel drain around Shirenewton

The wait is where kindly meant help does the harm. Stick to these.

  • Your safety comes before the car. Somewhere dangerous? Get away from the traffic and wait away from it. Fine where it stands? Stay with it.
  • A helpful passer-by doesn't fire it up. Nor does anyone checking it still does the trick, or rolling it a couple of yards.
  • Anything from your boot, oil made for two-strokes or injector cleaner: no additive lifts that petrol.
  • Siphoning petrol into a can at the roadside is risky — and it also leaves whatever fuel has already gone beyond your tank. Do not drain the car yourself.
  • Leave your ignition off — your windows and the radio too.

The fuel drain, step by step, after the van arrives

  • First, three queries: which fuel went in, the amount, and has it run? Those replies decide this job, so the quote follows them.
  • Out of the tank comes the contaminated mix: the tank is drained.
  • Petrol that has moved beyond the tank travels in the fuel lines once it ran, and your lines are rinsed to clear it.
  • Where the vehicle has a usable filter, it's changed; if not, cleared.
  • Fresh diesel in, and your system primed.
  • The start-up. With fresh diesel in and the system bled, it's fired up and tested to make sure it runs smoothly.

The vehicle has fresh diesel running through it before our engineers head off. Your car returns to normal use right away, and lasting damage is very rare if it has been caught soon.

After your fuel drain: back on the road around Shirenewton

  • Started on fresh diesel, it asks nothing special of you. Just drive normally.
  • Pull over and call us back if anything seems wrong early on — a light on the dash, smoke from the exhaust, an idle that runs rough, or a throttle with a dead spot.
  • Keep the documents. A hire firm, a fleet manager or an insurer may ask what was carried out.
  • Next time, trust the petrol pump's label instead of the colour of its handle.
