Clayton Brook: Petrol in a Diesel Car? Here Is What Happens

Not for a second, and not to move it: your motor remains off. Pause there. The coming few minutes decide it far more than anything else: petrol in a diesel still unrun generally comes down to draining and purging, right there. Anywhere you happen to be in Clayton Brook, this is the order things run from now.

Petrol in a diesel, engine off — the first minute

Before anything else, these — in this order.

  • Keys out of your ignition. Switching your ignition on can be enough to prime the fuel system, and priming pulls petrol out of the tank towards the components it damages. Leave it off altogether.
  • A fuller tank of the same mix is all adding diesel leaves you, because it takes out nothing. So no more diesel.
  • Get the vehicle easy to see first — hazards on — if there is traffic going past anywhere near you.
  • Off the pump by hand. On a forecourt, get the attendants to help you push it away from the pump. Don't fire it up to move it, however short the distance.
  • Keep your receipt: the fuel and roughly how much are printed on it, and they're what our engineers ask for first.

Still driving when you noticed? Come off the M61 at the next exit if that's where you are, under a mile from Clayton Brook, and stop somewhere safe instead of pressing on to the services. Then begin at step one.

Clayton Brook fuel drain: has your engine run yet, or not?

One answer is what everything after this stage rests on.

Engine never run at all?

  • The petrol is still inside your tank and nowhere else.
  • Draining and flushing, on the spot, is normally the whole job.
  • No position is better, and it's why the first stage counts so much.

If your engine has been run, even briefly:

  • Some petrol has left your tank already, passed through your filter, and got into the lines.
  • Run it further and that petrol gets to your injectors, having gone through your fuel pump first.
  • Distance is what turns it into a bigger job: flushed lines, a filter seen to, and at times further work.

Diesel keeps your high-pressure pump and the fuel injectors oiled as it runs through them. Petrol gives them nothing, and that is why the line is drawn there. In the tank, left alone, petrol does no harm. Petrol being pumped is wearing the parts that move the vehicle.

What to have prepared when you call about petrol in a diesel from Clayton Brook

Get ready a little, and the technician finds you rather than circling.

  • Where you are. A postcode starting PR5 8 is the ideal place to start.
  • A road name is a help: Tunley Holme, say, or whichever street you've stopped in. A car park works too.
  • Or the nearest landmark. A car park is quicker to find by what it serves, like the one at Lidl.
  • Make and model of the vehicle, and the fact it's a diesel.
  • Petrol or AdBlue? Say which. They are different jobs, and AdBlue has its own Clayton Brook page.
  • How much. Litres from the receipt, or how long the nozzle was in the filler.
  • The distance it did, and how heavily, if it ran at all.
  • Whose car it is. Some hire and company contracts want the owner to authorise this work, and that is quicker settled before our engineers turn up than after.

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

Waiting for a fuel drain in Clayton Brook: what to do

The wait is where well-meant help does the damage. Stick to these.

  • Stay with your car if it is safe where it is — but if it has stopped somewhere unsafe, you come first: away from the traffic, waiting apart from it.
  • Not to roll it a couple of yards, not to check it is all right, not for a passer-by's kindness: no one starts it.
  • Additives stay in your boot. Injector cleaner and two-stroke oil take none of the petrol out once more.
  • Siphoning petrol into a can at the roadside is hazardous — and it still leaves whatever fuel has already gone beyond that tank. Don't try a home-made drain.
  • Leave the ignition off — your windows and your radio included.

When the van arrives: your fuel drain, step by step

  • Fuel, quantity, whether it has run: the answers set this job, and that's why you get a price after them instead of before.
  • Then the tank is drained, so the contaminated fuel is taken out.
  • Petrol that has shifted beyond that tank sits in your lines if it ran, and the lines are rinsed to shift it.
  • The filter is dealt with. Cleared, or replaced where the vehicle has a workable one.
  • Priming comes once clean diesel is in.
  • Our engineers fire it up only after fresh diesel has gone in and bled the system, then confirm that it's running correctly.

We remain until it is running on fresh diesel. The vehicle goes back to normal use straight away, and long-term damage is very uncommon if it has been caught early.

After your fuel drain is done: driving in Clayton Brook once more

  • Once it's been started on fresh fuel, there is nothing special to do: drive normally.
  • Give the first miles your attention. Smoke appearing, a warning light coming on, the idle going lumpy or your throttle stumbling: pull over then call us back.
  • Your documents covers the query a rental company, fleet manager or insurer may ask: what work was carried out. Keep it.
  • The handle's colour is not the thing to go by next time — the label on the petrol pump is.
