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

Not for a second, and not to move it: the motor stays off. Pause there. Has not been run? Then petrol in a diesel tends to be a simple drain-and-flush job wherever the car has stopped — and no other factor decides that more than the next few minutes do. Here is the sequence of things from here, wherever you're around Foxcotte.

Minute one: petrol in a diesel, motor off

In this sequence, and before anything else:

  • Pull your keys out. Even your ignition on its own can prime the system, drawing petrol out of your tank to precisely the components it harms, so leave the vehicle off entirely.
  • No diesel on top. More fuel in removes none of that petrol — it just makes you with extra of the same blend.
  • Get the car simple to see before anything else — hazards on — if there's traffic going past anywhere close to you.
  • By hand, never on the motor: that is how it leaves the petrol pump. Get the forecourt staff to help you roll, whatever the mileage.
  • Keep the receipt: the grade and roughly how much are written on it, and they're what our engineers ask for first.

If you were still on the move when you noticed, pull over somewhere sensible instead of pushing on for the services — on the M3, under 15 miles from Foxcotte, that means the next exit. Step one comes next.

Has it run yet? The fork in each Foxcotte fuel drain

From this point on, everything hinges on a single answer.

Not run, not even briefly:

  • Nowhere but your tank: that is where that petrol yet is.
  • The work is a simple drain and a flush, usually done where the vehicle is.
  • This is the best spot to be in, and the whole reason stage one matters.

If the motor has run, even for a moment:

  • Out of your tank, past your filter, into your lines: that's how far that petrol has travelled.
  • On a longer run it has reached the high-pressure fuel pump and the fuel injectors.
  • Flushing the lines, the filter sorted, occasionally more: the job grows as the miles does.

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

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

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

Whether the technician goes round or finds you comes down to a little planning.

  • Where you are. A postcode starting SP10 4 is the ideal start.
  • Wherever you have parked, the road's name is useful — whether that's Foxcotte Lane or somewhere else — and so does the name of a car park.
  • Car parks are found most easily by what they serve: tell us the one outside Aldi, and it is straightforward.
  • The vehicle. Make, model, plus that it's a diesel.
  • Petrol or AdBlue? Tell us which. They are different jobs, and AdBlue has a separate Foxcotte page.
  • How much. Litres from your receipt, or how long the nozzle was in.
  • The mileage it did, and how heavily, if it ran at all.
  • Hire or company car? Some contracts want the owner's go-ahead for the work, and getting it before our technicians get there is faster than after.

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

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

The wait is where kindly meant help does the damage. Hold to these.

  • Your safety comes before the vehicle. Somewhere unsafe? Get clear of the traffic then wait away from it. Safe where it is? Wait with it.
  • Nobody starts it. Not a passer-by being kind, not to check it is all right, not to roll the vehicle a few yards.
  • None of that gets that petrol back out — not two-stroke oil, not injector cleaner, not anything from the boot. So no additives.
  • No DIY clearing. Siphoning petrol into a can by the kerbside is hazardous, and it leaves your fuel that has by now gone beyond the tank.
  • The ignition remains off. Even for the radio or your windows.

Step by step: your fuel drain when the van gets there

  • Three questions. What was put in, how much, and whether it has run. Those answers decide the job, which is why our quote comes after them and not before.
  • Your tank is cleared. The contaminated mix comes from that tank.
  • Cleaning the lines comes next, since a vehicle that ran has petrol past your tank, in the fuel lines themselves.
  • Cleaned, or changed if the vehicle has a usable one: the fuel filter is seen to next.
  • Clean diesel goes in, and the system is primed.
  • Starting up. When your system is bled with new diesel, our technicians start the car and confirm it runs correctly.

Our technicians stay until it is running on new diesel. The vehicle goes back to normal driving straight away, and lasting damage is very uncommon if it has been caught early.

Back on the road around Foxcotte after the fuel drain

  • Drive normally. There's nothing special to do after it's been started on clean fuel.
  • The first miles are the test. A warning lamp, exhaust smoke, a rough idle or a flat throttle is your cue to stop and call us a second time.
  • Hold on to the paperwork. A hire company, a fleet manager or an insurer may ask what was carried out.
  • Read the label on the petrol pump next time, not the colour of the handle.
