Petrol in a Diesel Car in New Cross: What Happens Now

Not for a moment, and not for moving it: your engine stays off. Pause there. Cleared and cleaned, right where it sits: that's generally all an unrun diesel with petrol in it needs. Whether it stays that straightforward rests on the minutes ahead far more than on anything else. From here on, step by step, wherever you are around New Cross:

Petrol in a diesel, motor off — the first minute

Work through the following in order, before you do anything else.

  • Bleeding the fuel system draws petrol from your tank toward the parts it damages, and switching the ignition on can be enough to do that. So your keys come out, and your ignition stays off completely.
  • A bigger tank of the same mixture is all adding diesel leaves you, since it takes out nothing. So no more diesel.
  • Make the car simple to see first — hazard lights on — if there is moving traffic anywhere close to you.
  • Off the petrol pump by hand. On a forecourt, get the attendants to help you push it clear of the pump. Don't crank it to shift it, however short the way.
  • Keep the receipt: the fuel and roughly how much are printed on it, and they're what our engineers ask about first.

On the M11, under 10 miles from New Cross, the next exit is the location to come off; anywhere, the first safe spot to stop. Do not push on to the services. Then go back to stage one.

Each New Cross fuel drain starts here: has your engine run?

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

If the motor has not run at all:

  • The petrol is still inside that tank and nowhere else.
  • The job is a drain and a flush, usually done where the car is.
  • Step one matters for exactly this reason: it is the best place to be in.

Engine run, even for a moment?

  • Your lines and the fuel filter now carry petrol drawn from your tank.
  • Run it further and the petrol reaches the fuel injectors, having passed through your fuel pump first.
  • The job grows with the distance — lines flushed, filter sorted, sometimes more.

The line falls there because diesel protects your high-pressure pump and your injectors on its way through them — and petrol does not. Petrol sitting in a tank damages nothing. Pump that petrol, though, and it grinds down the very parts doing the moving.

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

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

  • Where you have stopped. A postcode starting SE14 6 is the ideal place to start.
  • A road name is a help: Batavia Road, say, or whatever street you've stopped in. A car park does the trick too.
  • What a car park serves is the easiest way to find it, and so say the landmark — such as the one at Sainsbury's.
  • Make and model of your car, and the fact it's a diesel.
  • Which went in matters: AdBlue is a separate job from petrol, plus New Cross has a page for it. So tell us.
  • The amount: your receipt's litres, or otherwise how long you had the nozzle in.
  • If it has run, how far plus how hard — as well as if it has run at all.
  • Hire or company car? Some contracts need the owner's authorisation for the work, and getting it before our engineers arrive is faster than after.

Call 0333 366 0103 next. Writing to is fine too if it can wait, with your car left at home, going nowhere.

New Cross fuel drain on its way? Whilst you wait

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

  • Where the vehicle has stopped decides where you wait. Somewhere exposed: away from it, clear of the traffic. Sensible: with it. Either way, safety before your car.
  • Nobody — however kind — starts it, whether to see if it runs or to move the vehicle a short way.
  • None of it takes the petrol back out — not two-stroke oil, not injector cleaner, not something from the boot. So no additives.
  • Siphoning petrol into a can at the kerbside is dangerous — and it also leaves whatever fuel has already gone beyond that tank. Don't try a home-made drain.
  • The ignition remains off. Even for your radio or your windows.

Step by step: the fuel drain when the van arrives

  • Three questions. What was put in, how much, and whether it has run. Those answers set the job, which is why the price comes after them but not before.
  • The tank is drained. The contaminated blend comes from the tank.
  • Petrol that has moved beyond the tank sits in your lines once it ran, and your lines are rinsed to shift it.
  • The filter is sorted. Cleared, or changed where the car has a serviceable one.
  • Priming comes after fresh diesel is in.
  • We fire it up only after new diesel has gone in and primed your system, then make sure that it's running smoothly.

Your car has fresh diesel running through it before our technicians leave. It's very uncommon for a vehicle caught quickly to be left with permanent damage, and normal use resumes straight away.

After the fuel drain: back on the road around New Cross

  • Started on new diesel, it needs nothing unusual of you. Simply drive normally.
  • Pull over and ring us back if anything looks wrong early on — a light on the dash, smoke from your exhaust, an idle that runs rough, or a throttle with a dead spot.
  • An insurer, a fleet manager or a hire company may ask what was done, and so hold on to the paperwork.
  • The handle's colour isn't the guide to go by next time — the label on the petrol pump is.
