Petrol in a Diesel Car in Royston: What Happens Now

Not for a moment, and not to move it: the motor remains off. Pause there. Drained and flushed, just where it is: that's usually all an unrun diesel with petrol in it takes. Whether it remains that straightforward depends on the minutes ahead more than on everything else. From now on, in order, for anywhere in Royston:

Petrol in a diesel? What to do in minute one

First, these — following this order.

  • Bleeding the system draws petrol from your tank toward the parts it harms, and switching your ignition on can be all it takes to do that. So your keys come out, and the ignition remains off altogether.
  • Topping up with diesel sounds like it thins the problem. It does not: nothing gets out, and the tank simply holds more of the same.
  • Hazard lights on. If you're anywhere near moving traffic, make the vehicle easy to see before you do anything else.
  • However short the distance, starting it to move it is the mistake. On a forecourt, push the car away from the pump by hand instead, then ask the staff to lend a hand.
  • Which fuel, and roughly how much? The receipt answers that, and that's where our questions start. Don't bin it.

Realised on the move? Get off at the next exit if you're on the M11, under 10 miles from Royston, and stop somewhere safe — not at the services farther on. Stage one comes after that.

The fork in every Royston fuel drain: has it run yet?

One answer is what everything after this point depends on.

If it has never been started:

  • Only that tank has petrol in it so far.
  • The work is a drain and a flush, normally done where the vehicle is.
  • No spot is better, and it's why the first step counts so much.

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

  • From that tank, through your filter, into the lines: that's how far the petrol has travelled.
  • Run it farther and that petrol reaches the injectors, having gone through your pump first.
  • The further it went, the larger this job — the fuel lines, the filter, and now and then more besides.

Diesel keeps your high-pressure pump and the injectors oiled as it goes through them. Petrol gives them nothing, and that is why the line is drawn there. A tank of petrol, left alone, damages nothing. Pump the petrol, though, and it grinds down the very parts doing the moving.

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

A technician that circles versus a van that finds you: a little planning is what separates them.

  • SG8 7 and the rest of the postcode is the ideal way to start telling us where you are.
  • Wherever you have parked, the road's name helps — whether that is A10 or somewhere else — and so does the name of a car park.
  • Describe a car park by what it serves — the one at Market One, for example — and it's much easier to find.
  • That it is a diesel, plus the make and model of the car.
  • Which was put in matters: AdBlue is a separate job from petrol, plus Royston has a page for it. So say.
  • Roughly how much — in litres from your receipt, or by how long the nozzle was in.
  • The distance it did, and how heavily, if it has run at all.
  • The owner may have to authorise this work under some hire or company contracts — so it is quicker to settle whose car it is before we get there.

Then phone 0333 366 0103. If it can wait — your car is at home and going nowhere — does the trick too.

Royston fuel drain on its way? While you wait

During the wait, the harm comes from well-meant help — which is why these matter.

  • Stay with the car if it is safe where it is — but if it has stopped somewhere exposed, you come first: away from the traffic, waiting apart from it.
  • Nobody starts it. Not a passer-by being kind, not to check it is all right, not to roll the vehicle a couple of yards.
  • None of it takes that petrol back out — not two-stroke oil, not injector cleaner, not something from the boot. So no additives.
  • Clearing it yourself is out: a can of siphoned petrol on a verge is a danger, and the fuel beyond your tank stays put anyway.
  • Even your radio or your windows aren't worth turning your ignition on for.

When the van gets there: the fuel drain, step by step

  • Three questions. What was put in, how much, and if it has run. The answers shape this job, which is why the quote comes after them and not before.
  • Next the tank is emptied, and the polluted fuel is taken out.
  • Flushing the lines follows, because a car that ran has petrol past that tank, in your lines themselves.
  • Cleared, or replaced if the car has a usable one: the filter is sorted next.
  • Fresh diesel goes in, then the fuel system is primed.
  • First start on fresh diesel. Once priming is done, the motor is fired up and our technicians check that it runs smoothly.

Until it runs on fresh diesel, our engineers stay with it. The car goes back to normal use at once, and lasting damage is very uncommon when it has been noticed soon.

Royston, after the fuel drain: back on the road

  • Drive normally. There's nothing special to do once it has been started on clean fuel.
  • Pull over and ring us back if anything looks 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 documents covers the question a rental company, fleet manager or insurer may ask: what work was carried out. File it.
  • Check the label on the pump next time, not the colour of the handle.
