Houghton Regis: Petrol in a Diesel Car? Here Is What Happens

Stop. Engine off. Leave the vehicle that way — no second on, no moving it at all. Petrol in a diesel that has not been run is typically a simple drain and a flush, done where the vehicle sits, and what you do in the next few minutes settles that far more than anything else. From now on, step by step, wherever you are around Houghton Regis:

Petrol in a diesel, engine off — the first minute

Go through these in order, before you do anything else.

  • The keys out of the ignition. Turning your ignition on can be enough to prime your fuel system, while priming pulls petrol out of the tank towards the parts it harms. Leave the vehicle off completely.
  • No diesel on top. More fuel in takes away none of that petrol — it just leaves you with extra of the same mixture.
  • Close to moving traffic? Then the hazards go on before anything else, and so your car is easy to see.
  • By hand, not under the engine: that is how it leaves the pump. Ask the forecourt attendants to help you push, however short the miles.
  • The first question you will be asked is which fuel went in and about how much — and the till receipt shows both. Keep it.

On the M1, under 3 miles from Houghton Regis, the next exit is the spot to leave it; elsewhere, the first safe location to stop. Do not push on to the services. Then go back to step one.

Houghton Regis fuel drain: has your motor run yet, or not?

What comes after this turns on one answer, and only one.

Not run, not even once:

  • No place but that tank: that's where the petrol yet is.
  • Normally it's emptied and rinsed just where your car stands.
  • This is the best case — which is the whole point of stage one.

Motor run, however for a moment?

  • Some petrol has left your tank already, gone through your filter, and got into the fuel lines.
  • On a longer run it has got to your high-pressure pump and the injectors.
  • The further it went, the larger this job — the lines, the filter, and sometimes more besides.

That line falls there since diesel lubricates your high-pressure pump and the injectors on its way through them — and petrol doesn't. In that tank, sitting still, petrol harms nothing. Move the petrol, though, and it wears the very parts doing the moving.

Houghton Regis, petrol in a diesel: have these ready before you call

Whether the technician goes round or finds you depends on a little planning.

  • LU5 5 plus the rest of the postcode makes the ideal way to start telling us where you are.
  • The road or the car park. A road name helps — Peel Street, or wherever you have pulled up.
  • What a car park serves is the quickest way to find it, so say the landmark — such as the one outside Morrisons.
  • The car. Make, model, and that it's a diesel.
  • Which was put in counts: AdBlue is a separate job from petrol, plus Houghton Regis has a page for it. So say.
  • Roughly how much — in litres from the receipt, or by how long the nozzle stayed in.
  • The miles it did, and how hard, if it ran at all.
  • The owner may have to authorise this work under some hire or company contracts — which is why it is faster to settle whose car it is before our engineers get there.

Ring 0333 366 0103 once you've got that together — or, if the vehicle is at home, going nowhere, use .

Waiting for a fuel drain in Houghton Regis: what to do

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

  • Safety before the car. If it has stopped somewhere exposed, get yourself clear of the traffic then wait away from it. If it is safe where it is, wait with it.
  • No one starts it. Not a passer-by being kind, not to check it is all right, not to roll it a couple of yards.
  • None of that gets the petrol back out — not two-stroke oil, not injector cleaner, not something from the boot. So no additives.
  • Siphoning petrol into a can by the roadside is risky — and it still leaves whatever fuel has already gone beyond the tank. Don't try a home-made drain.
  • Not for your radio, not for your windows: the ignition stays off.

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

  • The quote comes after three questions, not before them — what was put in, how much, and whether it's run — since those answers decide this job.
  • The tank is cleared. The tainted mix comes out of your tank.
  • If it ran, the fuel lines are carrying petrol that has moved beyond the tank — so they are cleaned.
  • Cleaned, or swapped if the car has a workable one: the filter is dealt with next.
  • Priming follows once clean diesel is in.
  • Starting the car. After the system is bled with fresh diesel, we fire it up and make sure it runs properly.

Our engineers stay until it's running on fresh diesel. It is very unusual for a car spotted quickly to be left with permanent damage, and normal driving resumes at once.

After the fuel drain is done: driving in Houghton Regis once more

  • Drive normally. There is nothing unusual to do once it's been started on fresh fuel.
  • Pull over and ring us back if anything seems wrong early on — a light on your dash, smoke from the exhaust, an idle that is lumpy, or a throttle with a dead spot.
  • Your documents answers the query a rental company, fleet manager or insurer may ask: what work was carried out. Keep it.
  • Next time, check the pump. The label, not the colour of the handle.
