What Happens Now: Petrol in a Diesel Car in Blowinghouse

Not for a moment, and not for moving it: the engine stays off. Pause there. Petrol in a diesel that has not been run is typically a drain plus a flush, done where your vehicle stands, and what you do in the next few minutes decides that far more than anything else. From now on, step by step, for anywhere in Blowinghouse:

Minute one: petrol in a diesel, motor off

In this order, all before everything else:

  • Keys out of the ignition. Turning your ignition on can be enough to prime the system, and priming draws petrol out of your tank towards the components it harms. Leave the car off altogether.
  • No diesel on top. More fuel in removes none of that petrol — it just makes you with extra of the same blend.
  • Hazard lights on. If you are at all close to moving traffic, make the vehicle easy to see before you do anything else.
  • Off the pump by hand. At a forecourt, ask the staff to help you roll it clear of the pump. Don't fire it up to move it, however short the distance.
  • The first question you will be asked is which fuel went in and about how much — and your receipt shows both. Hold on to it.

Realised on the move? Get off at the next junction if you're on the M5, over 50 miles from Blowinghouse, and pull over somewhere safe — not at the services further on. Stage one comes after that.

Has it run yet? The fork in each Blowinghouse fuel drain

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

Not run, not even briefly:

  • Only that tank has petrol in it for now.
  • Where your car sits is usually where the work happens: a drain, then a flush.
  • No spot is better, and it is why the first stage counts so much.

If the engine has been run, even for a moment:

  • The fuel lines and the filter already carry petrol pulled out of the tank.
  • A bigger run takes it right through to the high-pressure fuel pump and the fuel injectors.
  • Flushing your lines, your filter seen to, occasionally more: this job expands as the distance does.

Petrol does not lubricate. Diesel does, protecting the high-pressure pump and injectors as it passes through, which is why the line sits where it does. In your tank, sitting still, petrol does no harm. As soon as it's pumped, petrol begins grinding whatever moves it.

What to have ready when you call about petrol in a diesel from Blowinghouse

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

  • TR15 3 plus the rest of the postcode makes the best way to begin telling us where you are.
  • A road name is a help: Barncoose Avenue, say, or whatever street you've stopped in. A car park works too.
  • Describe a car park by what it serves — the one at Co-op Food, for instance — and it's far easier to find.
  • The car. Make, model, and that it's a diesel.
  • What went in. Petrol, or AdBlue. AdBlue is a separate job with its own page for Blowinghouse, so tell us which.
  • About how much — in litres from your receipt, or by how long the nozzle was in.
  • The miles it did, and how heavily, if it has run at all.
  • Settle who owns the vehicle ahead of when we get there: some hire or company agreements want the owner to authorise the work, and that is quicker beforehand.

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

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

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

  • Your safety comes before your car. Somewhere unsafe? Get away from the traffic and wait away from it. Fine where it is? Wait with it.
  • No one starts it. Not a passer-by being helpful, not to check it is all right, not to roll the car a few yards.
  • Additives stay in your boot. Injector cleaner and two-stroke oil draw none of the petrol out again.
  • Siphoning petrol into a can by the kerbside is dangerous — and it also leaves whatever fuel has already gone beyond the tank. Don't drain the vehicle yourself.
  • The ignition remains off. Even for the radio or your windows.

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

  • Three queries. What was put in, how much, and whether it has run. Those answers decide the job, which is why the price comes after them but not before.
  • Then your tank is drained, so the tainted fuel comes out.
  • If it ran, your lines are carrying petrol that has moved beyond your tank — so they are flushed.
  • The filter is dealt with. Cleared, or replaced where the vehicle has a workable one.
  • The system is primed with fresh diesel.
  • The start-up. With clean diesel in and your system primed, it's fired up and tested to make sure it runs correctly.

Only once it is running on new diesel do our engineers head off. It is very rare for a vehicle spotted soon to be left with long-term damage, and normal use resumes at once.

After your fuel drain is done: driving around Blowinghouse a second time

  • Nothing unusual is needed after a start with fresh diesel — normal driving will do.
  • Give the first miles your attention. Smoke appearing, a warning light coming on, the idle going lumpy or the throttle stumbling: pull over then call us back.
  • The work may matter later with a hire company, an insurer or a fleet manager. Keep your paperwork.
  • Check the label on the pump next time, not the colour of its handle.
