Upper Norwood: Petrol in a Diesel Car? Here Is What Happens

Stop, then keep your engine off — not on, and not for a moment to shift the vehicle. Drained then cleaned, just where it sits: that is usually all an unrun diesel with petrol in it takes. Whether it remains that simple rests on the minutes to come far more than on anything else. Here's the order of things from now, wherever you're around Upper Norwood.

Minute one: petrol in a diesel, engine off

Do these before anything else, in this sequence.

  • Priming your fuel system draws petrol from the tank toward the components it harms, and turning your ignition on can be enough to do that. So the keys get taken out, and the ignition stays off completely.
  • Topping up with diesel seems like it dilutes the issue. It does not: nothing gets out, and the tank simply carries more of the same.
  • Hazard lights on. If you're anywhere close to moving traffic, make the car easy to see before you do anything else.
  • The attendants will usually help you roll it clear of the pump. Ask, and roll it by hand — not on your engine, even for a couple of yards.
  • Hold on to the receipt. It shows which fuel was put in plus about how much, which is the first thing we'll ask.

Still on the move when you realised? Come off the M23 at the next exit if that is where you are, under 10 miles from Upper Norwood, and pull over somewhere sensible rather than pushing on to the services. Then start at step one.

Upper Norwood fuel drain: has your motor run yet, or not?

Everything after this stage depends on one answer.

Motor not run at all?

  • Only that tank has petrol in it for now.
  • Where the vehicle sits is usually where this work happens: a drain, then a flush.
  • Step one matters for precisely this reason: it is the best position to be in.

Run at all, even for a second:

  • From that tank, past the fuel filter, into your lines: that's how far the petrol has travelled.
  • The high-pressure pump and the fuel injectors see it too on a bigger run.
  • Miles is what makes it a larger job: flushed lines, a filter seen to, and at times more than that.

The reason the line falls there: diesel protects the high-pressure pump as well as the injectors as it flows through them, and petrol does not. Nothing is damaged by petrol that is just resting in a tank. The parts that move it are grinding the moment petrol is being pumped.

Upper Norwood, petrol in a diesel: have these ready before you call

Get ready a little, and the van finds you instead of circling.

  • The best start is a postcode — one beginning SE19 3 — for where you are.
  • Give the road — Ravensdale Gardens or wherever you have pulled up — or the car park.
  • Describe a car park by what it serves — the one at Sainsbury's, for example — and it is much quicker to find.
  • The car. Make, model, and that it is a diesel.
  • Which was put in counts: AdBlue is a separate job from petrol, and Upper Norwood has a page just for that. So tell us.
  • About how much — in litres from the receipt, or by how long the nozzle stayed in.
  • Has it run? If so, tell us how far it went, and the way it was driven.
  • Hire or company car? Some agreements need the owner's authorisation for the work, and sorting it before we arrive is quicker than after.

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

Whilst you wait for a fuel drain around Upper Norwood

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

  • Your safety comes before your car. Somewhere unsafe? Get clear of the traffic then wait away from it. Safe where it is? Stay with it.
  • Nobody — however helpful — starts it, whether to see if it runs or to move the car a short way.
  • No additives. Two-stroke oil, injector cleaner, something from your boot — none of it gets that petrol back out.
  • Siphoning petrol into a can by the roadside is dangerous — and it still leaves whatever fuel has already gone beyond your tank. Do not try a home-made drain.
  • Ignition stays off. Even for your radio or the windows.

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

  • First, three questions: which fuel was put in, the quantity, and has it run? Those replies set the job, so our price follows them.
  • Next the tank is cleared, and the contaminated fuel comes out.
  • Purging the fuel lines comes next, because a motor that ran has petrol past the tank, in your lines themselves.
  • Then the fuel filter: swapped where there is a usable one, cleared where there is not.
  • Fresh diesel in, and your system primed.
  • Starting the car. When the system is primed with clean diesel, our engineers fire it up and confirm it runs correctly.

The car has clean diesel running through it before our engineers leave. Permanent damage is very rare if it has been spotted soon, so your car can go right back to normal use.

Back on the road in Upper Norwood after your fuel drain

  • Once it has been started on fresh fuel, there's nothing unusual to do: drive normally.
  • Give the first miles your attention. Smoke showing, a warning light coming on, your idle going lumpy or the throttle hesitating: pull over then ring us back.
  • An insurer, a fleet manager or a hire company may ask what was done, and so hold on to the paperwork.
  • The handle's colour isn't the guide to go by next time — the label on the pump is.
