Petrol in Diesel

The Next Steps, in Order: Petrol in a Diesel Car in Kempston

Stop, and keep your engine off — not on, and not for a second to move the car. Hasn't been run? Then petrol in a diesel will usually be a simple drain-and-flush job wherever the car has stopped — and nothing settles that as much as the next few minutes do. What follows is the sequence from here, wherever in Kempston you happen to be.

Petrol in a diesel, motor off — the first minute

First, these — following this sequence.

  • Take the keys out. Even the ignition on its own can prime your fuel system, pulling petrol out of your tank to exactly the parts it damages, so leave the vehicle alone wholly.
  • A bigger tank of the same mixture is all topping up gives you, because it takes out nothing. So no extra diesel.
  • Being seen comes before the rest near moving traffic: put the hazard lights on, and only then deal with anything else.
  • However short the distance, starting it to shift it is the mistake. At a forecourt, roll the vehicle clear of the pump by hand instead, and ask the attendants to help.
  • Hold on to the receipt: the grade and the rough amount are written on it, and they are what our technicians ask for first.

If you were still on the move when you realised, stop somewhere sensible instead of pushing on for the services — on the M1, under 10 miles from Kempston, that means the next exit. Step one comes next.

The fork in each Kempston fuel drain: has it run yet?

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

If the engine hasn't run at all:

  • Only the tank has petrol in it so far.
  • The work is a drain and a flush, normally done where the vehicle is.
  • Being here is the best case — which is the entire point of step one.

If it's been started, even for a moment:

  • Some petrol has left that tank already, gone through the filter, and reached the lines.
  • Run it further and that petrol reaches your injectors, having passed through the pump first.
  • Miles is what makes it a larger job: flushed lines, a filter seen to, and at times more than that.

The reason the line falls there: diesel lubricates your high-pressure pump as well as the injectors as it flows through them, and petrol doesn't. Petrol sitting in a tank damages nothing. Petrol being pumped is wearing the components that shift it.

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

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

  • Your whereabouts: a postcode beginning MK42 7 serves best.
  • The street or the car park. A road name helps — Bedford Road, or wherever you have pulled up.
  • Or the landmark. A car park is easier to find by what it serves, such as the one outside Co-op Food.
  • That it is a diesel, along with the make and model of your vehicle.
  • Tell us which was put in — petrol or AdBlue — since AdBlue is a different job, with a page of its own for Kempston.
  • The amount: the receipt's litres, or else how long you had the nozzle in.
  • If it's run, how far and how heavily — and whether it's run at all.
  • Hire or company car? Some contracts want the owner's authorisation for the work, and getting it before our engineers get there is quicker than afterwards.

Ring 0333 366 0103 once you have got that together — or, if your car is at home, going nowhere, use .

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

Help, however well meant, is what does the damage whilst you wait. So hold to these.

  • Your safety comes before the vehicle. Somewhere exposed? Get clear of the traffic then wait away from it. Safe where it is? Stay with it.
  • No one — however kind — starts it, whether to see if it runs or to move the vehicle a short way.
  • No additives. Two-stroke oil, injector cleaner, anything from the boot — none of it gets that petrol back out.
  • Clearing it yourself is out: a can of siphoned petrol on a verge is a danger, and your fuel beyond the tank stays where it is anyway.
  • Not for your radio, not for the windows: the ignition remains off.

When our van gets there: your fuel drain, step by step

  • The quote comes after three questions, not before them — what got in, how much, and if it has run — since the replies decide the job.
  • The tank is drained. The contaminated mixture comes from the tank.
  • Flushing the lines comes next, because a car that ran has petrol past your tank, in the lines themselves.
  • Cleared, or replaced if the vehicle has a workable one: the fuel filter is seen to next.
  • Your system is primed with fresh diesel.
  • Our technicians fire it up only after fresh diesel has gone in and primed the system, then check that it is running properly.

Only when it is running on clean diesel do we leave. When it has been noticed quickly, lasting damage is very unusual, and the vehicle returns to normal driving right away.

After your fuel drain is done: driving in Kempston again

  • Nothing special is needed after a start with fresh diesel — ordinary driving is all.
  • Pull over and ring 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.
  • The work may matter later with a hire company, an insurer or a fleet manager. Keep the documents.
  • Check the label on the petrol pump next time, not the colour of the handle.
