Sidcup: Petrol in a Diesel Car? Here Is What Happens

Not for a moment, and not to move it: the engine stays off. Stop there. Has not been run? Then petrol in a diesel tends to be a straightforward drain-and-flush job wherever the vehicle has stopped — and nothing decides that more than the next few minutes do. Here's the sequence of things from here, anywhere you are around Sidcup.

Minute one: petrol in a diesel, engine off

Do these first, in this order.

  • The ignition off, keys out. Turned on, the ignition can prime your system — and priming is what draws petrol out of your tank into the parts it harms.
  • Topping up with diesel seems like it thins the issue. It doesn't: nothing gets out, and that tank simply holds more of the same.
  • Hazard lights on. If you're anywhere near moving traffic, make the car easy to see before you do anything else.
  • However short the way, starting it to shift it is the thing to avoid. At a forecourt, roll it away from the petrol pump by hand instead, then ask the staff to help.
  • Hold on to your receipt. It says which fuel got in and roughly how much, which is the first thing we will ask.

On the M20, under 5 miles from Sidcup, the next junction is the location to come off; anywhere, the first safe place to stop. Don't press on to the services. Then go back to stage one.

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

Everything after this stage rests on one answer.

If it has never been started:

  • All the petrol remains in that tank, and just there.
  • Usually it is drained and purged just where the vehicle stands.
  • Stage one counts for exactly this reason: it is the best place to be in.

Run at all, however briefly:

  • The lines and your filter already carry petrol drawn out of your tank.
  • On a bigger run it has got to the high-pressure fuel pump as well as the fuel injectors.
  • The job expands with the distance — lines cleaned, filter sorted, occasionally more.

Diesel keeps the high-pressure pump and the fuel injectors protected as it runs through them. Petrol offers them nothing, and that is why the line is drawn there. In your tank, sitting still, petrol harms nothing. Petrol being pumped is grinding down the components that shift the car.

Calling about petrol in a diesel from Sidcup: what to have ready

Whether the van goes round or finds you comes down to a little preparation.

  • DA15 7 plus the remainder of the postcode makes the ideal way to start telling us where you are.
  • Name the road — Hurst Road or wherever you have pulled up — or the car park.
  • Or the landmark. A car park is quicker to find by what it serves, like the one outside Morrisons.
  • The car. Make, model, and that it's a diesel.
  • Say which was put in — petrol or AdBlue — since AdBlue is a different job, with a page of its own for Sidcup.
  • How long the nozzle was in, or the litres on the receipt — either gives us how much.
  • If it's run, how far and how heavily — as well as if it's run at all.
  • Whose vehicle it is. Some hire and company contracts want the owner to authorise the work, and that's easier settled before we get there than after.

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

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

During the wait, the harm comes from well-intended help — so these count.

  • Where the car has stopped decides where you wait. Somewhere exposed: away from it, away from the traffic. Safe: with it. Either way, safety before the vehicle.
  • A helpful passer-by does not crank it. Nor does anyone checking it still does the trick, or moving it a few yards.
  • No additives. Two-stroke oil, injector cleaner, anything from the boot — none of it gets that petrol back out.
  • Siphoning petrol into a can at the kerbside is dangerous — and it also leaves whatever fuel has already gone beyond that tank. Don't try a home-made drain.
  • Not for the radio, not for your windows: the ignition stays off.

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

  • Fuel, volume, whether it's run: those answers set this job, and that is why you get a price after them rather than before.
  • Then your tank is cleared, so the tainted fuel comes out.
  • If it ran, the lines are carrying petrol that has shifted beyond your tank — so they're cleaned.
  • Then the filter: replaced where there's a serviceable one, cleared where there's not.
  • Fresh diesel in, and your system primed.
  • Our technicians start the engine only after clean diesel has gone in and bled the system, then check that it is running correctly.

Your car has fresh diesel running through it before our engineers go. The car goes back to normal use straight away, and long-term damage is very unusual when it has been caught early.

Sidcup, after the fuel drain: back on the road

  • Drive normally. There's nothing unusual to do once it's been started on clean fuel.
  • Pull over and call us back if anything looks wrong early on — a light on your dash, smoke from your exhaust, an idle that is lumpy, or a throttle with a dead spot.
  • Your paperwork answers the question a rental company, fleet manager or insurer may ask: what work was carried out. Keep it.
  • Next time, trust the pump's label instead of the colour of its handle.
