What Happens Now: Petrol in a Diesel Car in Faerdre

Stop, and keep your engine off — not on, and not for a moment to shift the car. Petrol in a diesel that has not been run is usually a simple drain and a flush, done where your vehicle sits, and what happens in the next few minutes determines that more than anything else. From here on, step by step, for anywhere around Faerdre:

Minute one: petrol in a diesel, engine off

In this sequence, and before everything else:

  • Keys out of the ignition. Switching your ignition on can be all it takes to prime your fuel system, and priming pulls petrol out of your tank towards the parts it harms. Leave the car off completely.
  • Topping up with diesel seems like it thins the problem. It does not: nothing comes out, and the tank simply carries more of the same.
  • Hazards on. If you are at all close to moving traffic, make the vehicle easy to see before you do anything else.
  • Off the petrol pump by hand. On a forecourt, get the staff to help you roll the car clear of the pump. Do not start it to move it, however short the distance.
  • Which fuel, and roughly how much? Your receipt replies both, and that's where our first question starts. Never bin it.

On the M4, under 3 miles from Faerdre, the next junction is the spot to leave the car; anywhere, the first sensible place to stop. Don't push on to the services. Then go back to step one.

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

Everything after this stage depends on one answer.

Not run, not even briefly:

  • No place but your tank: that's where the petrol still is.
  • Normally it is drained and flushed just where your car stands.
  • This is as good as it gets — which is the entire point of step one.

If it has been started, even for a moment:

  • Some petrol has left that tank by now, passed through the filter, and got into the fuel lines.
  • A bigger run carries it all the way to your high-pressure pump and your injectors.
  • Miles is what makes it a larger job: the lines flushed, a filter seen to, and at times further work.

The reason the line falls there: diesel protects the high-pressure fuel pump as well as the injectors as it passes through them, and petrol does not. A tank of petrol, left alone, damages nothing. Move that petrol, though, and it grinds down the very parts doing the moving.

Fuel drain of a diesel car in Faerdre, step by step

Before you call about petrol in a diesel in Faerdre: what our technicians need

Prepare a little, and the van finds you instead of circling.

  • The ideal start is a postcode — one beginning SA7 9 — for where you have stopped.
  • The street or the car park. A road name is a help — Gellionnen Close, or wherever you have stopped.
  • What a car park serves is the quickest way to find it, and so mention the landmark — like the one at Spar.
  • Make and model of your vehicle, and the fact it is a diesel.
  • Petrol or AdBlue? Tell us which. They are separate jobs, and AdBlue has its own Faerdre page.
  • How long the nozzle was in, or the litres on your receipt — either gives us how much.
  • If it's run, how far and how hard — as well as whether it's run at all.
  • Settle who has the vehicle ahead of when we arrive: some hire or company agreements want the owner to approve the work, and doing it faster first.

Call 0333 366 0103 then. Writing to works as well if it can wait, with the car parked at home, going nowhere.

The wait for a Faerdre fuel drain, and what to do in it

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

  • Where your car has stopped settles where you wait. Exposed: away from it, away from the traffic. Safe: with it. Either way, safety before the car.
  • Not to roll it a few yards, not to check it is all right, not for a passer-by's kindness: no one starts it.
  • No additives. Two-stroke oil, injector cleaner, anything from your boot — none of it takes the petrol back out.
  • A home-made drain leaves your fuel already gone beyond the tank, and siphoning petrol by the road is hazardous besides.
  • Leave the ignition off — your windows and your radio too.

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

  • Fuel, volume, whether it's run: those answers set this job, and that is why we give a price after them rather than before.
  • Next that tank is emptied, and the tainted fuel is taken out.
  • Rinsing your lines follows, because a motor that ran has petrol past your tank, inside the lines themselves.
  • Cleaned, or swapped if the car has a usable one: the fuel filter is seen to next.
  • Clean diesel in, and your system primed.
  • Starting up. After the system is primed with clean diesel, our technicians fire it up and confirm it runs correctly.

Our technicians wait until it's running on new diesel. It's very rare for a car noticed soon to be left with lasting damage, and normal use starts again right away.

Once your fuel drain is done: driving around Faerdre once more

  • Once it has been started on fresh fuel, there is nothing unusual to do: drive normally.
  • The first miles are the test. A warning lamp, exhaust smoke, a rough idle or a flat throttle is your signal to stop and call us a second time.
  • Keep the paperwork. A hire firm, a fleet manager or an insurer may ask what was done.
  • Next time, read the petrol pump. The label, not the colour of the handle.
