St Martins: Petrol in a Diesel Car? Here Is What Happens

Not for a second, and not for moving it: your engine remains off. Pause there. Cleared and rinsed, right where it sits: that is generally all an unrun diesel with petrol in it needs. Whether it remains that simple rests on the minutes to come far more than on everything else. Wherever you are around St Martins, this is the order things run from now.

Minute one: petrol in a diesel, motor off

Work through the following first, in this sequence.

  • The ignition off, keys out. Turned on, your ignition can prime your system — and priming is what moves petrol out of the tank towards the components it damages.
  • No diesel on top. More fuel in removes none of the petrol — it only leaves you with more of the same mixture.
  • Near passing traffic? Then the hazards go on before anything else, so the car is simple to spot.
  • By hand, not under the engine: that is how it comes off the petrol pump. Ask the forecourt attendants to help you push, however short the mileage.
  • Which fuel, and about how much? Your receipt replies both, and that is where our questions start. Do not throw it away.

On the M4, under 3 miles from St Martins, the next junction is the location to leave it; elsewhere, the first sensible location to stop. Don't push on to the services. Then go back to step one.

Every St Martins fuel drain starts here: has the engine run?

One answer is what everything after this point rests on.

If it has never been started:

  • Only that tank has petrol in it so far.
  • Where the vehicle sits is normally where the work is done: a drain, then a flush.
  • Step one counts for precisely this reason: it is the best position to be in.

Motor run, even for a moment?

  • Petrol has been pulled from that tank, through the filter then into the fuel lines.
  • Run it farther and the petrol reaches the fuel injectors, having passed through your fuel pump first.
  • Flushing your lines, the filter dealt with, and sometimes more: the job expands as the miles does.

Diesel keeps the high-pressure fuel pump and the fuel injectors protected as it goes through them. Petrol gives them nothing, and that's why the line is drawn there. In the tank, left alone, petrol does no harm. Pump the petrol, though, and it grinds down the very parts that move it.

St Martins, petrol in a diesel: have these prepared before you call

A little preparation is the difference between a technician that finds you and a van that circles.

  • The ideal start is a postcode — one beginning CF83 1 — for where you are.
  • Wherever you have pulled up, the road's name helps — whether that is Redbrook Court or somewhere else — and so does the name of a car park.
  • What a car park serves is the easiest way to find it, so say the landmark — such as the one outside Heron Foods.
  • The car. Make, model, and that it is a diesel.
  • What was put in. Petrol, or AdBlue. AdBlue is a different job with its own page for St Martins, so say which.
  • How much. Litres from your receipt, or how long the nozzle was in.
  • Has it run? If so, say how far it went, and how it was driven.
  • Hire or company car? Some contracts want the owner's authorisation for the work, and getting it before our engineers turn up is quicker than afterwards.

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

While you wait for a fuel drain in St Martins

Hold to these: kindly meant help causes the damage during the wait.

  • Safety before your car. If it has stopped somewhere unsafe, get yourself clear of the traffic and wait away from it. If it is safe where it is, wait with it.
  • A kind passer-by does not fire it up. Nor does anyone checking it still works, or rolling it a couple of yards.
  • Anything from your boot, oil made for two-strokes or injector cleaner: no additive lifts the petrol.
  • No home-made draining. Siphoning petrol into a can at the kerbside is hazardous, and it leaves your fuel that has already gone beyond the tank.
  • The ignition stays off. Even for the radio or the windows.

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

  • Three questions. What got in, how much, and whether it has run. Those replies set this job, which is why our quote comes after them but not before.
  • Next the tank is drained, so the tainted fuel comes out.
  • Petrol that has moved beyond that tank travels in the lines once it ran, and the fuel lines are purged to clear it.
  • Where the car has a workable filter, it is swapped; otherwise, cleared.
  • Your system is primed on fresh diesel.
  • First start on new diesel. Once priming is done, the motor is started and our engineers make sure that it runs properly.

Until it runs on clean diesel, we stay with it. When it has been noticed early, lasting damage is very unusual, and the vehicle returns to normal driving at once.

St Martins, after your fuel drain: back on the road

  • After it's been started on clean fuel, there's nothing unusual to do: drive normally.
  • Give the first miles your attention. Smoke appearing, a warning light coming on, the idle going lumpy or your throttle hesitating: pull over and ring us back.
  • The work may matter later with a hire firm, an insurer or a fleet manager. Hold on to the documents.
  • Next time, check the petrol pump. The label, not the colour of its handle.
