# What Happens Now: Petrol in a Diesel Car in Cappagh

Whatever you do, don't switch the engine on, even briefly, to shift the car. Stop; leave it off.

The next few minutes settle it more than anything else: petrol in a diesel still unrun usually comes down to draining and purging, right there.

Below is the order from here, wherever in Cappagh you happen to be.

## Petrol in a diesel, motor off — the first minute

In this sequence, all before everything else:

- Priming the fuel system draws petrol from your tank towards the parts it damages, and turning your ignition on can be enough to do that. So the keys come out, and your ignition stays off completely.

- A bigger tank of the same mix is all topping up gives you, since it removes nothing. So no more diesel.

- Hazard lights on. If you're at all close to moving traffic, make the car simple to see before you do anything else.

- The attendants will normally help you roll it clear of the petrol pump. Ask, and roll it by hand — not on your engine, even for a couple of yards.

- Keep the receipt. It shows which fuel was put in and roughly how much, which is the first thing we'll ask.

If you were still on the move when you realised, stop somewhere sensible instead of pushing on for the services — on the M77, over 50 miles from Cappagh, that means the next junction. Stage one follows.

## Has it run yet? The fork in every Cappagh fuel drain

Everything after this point rests on one answer.

If it has not once been started:

- The petrol remains in that tank, and just there.

- Usually it's drained and rinsed right where the vehicle stands.

- Stage one matters for exactly this reason: it is the best spot to be in.

Motor run, even for a moment?

- Out of that tank, past the filter, into the lines: that's how far the petrol has got.

- The high-pressure fuel pump as well as the injectors get it on a longer run.

- Lines flushed, your filter dealt with, and sometimes more: the job grows as the miles does.

The line falls there because diesel lubricates the high-pressure pump and your injectors on its way through them — and petrol does not.

A tank of petrol, left still, damages nothing.

Petrol being pumped is grinding down the components that shift the vehicle.

## What to have prepared when you call about petrol in a diesel from Cappagh

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

- Your location: a postcode starting BT70 2 serves best.

- Wherever you have parked, the road's name helps — whether that is Wallace Cottages or somewhere else — and so does the name of a car park.

- Describe a car park by what it serves — the one outside the local shops, for example — and it is much quicker to find.

- That it is a diesel, along with the make and model of your vehicle.

- What was put in. Petrol, or AdBlue. AdBlue is a different job with its own page for Cappagh, so tell us which.

- How long the nozzle was in, or the litres from your receipt — whichever gives us how much.

- Whether it has run. And if it has, how far plus how heavily.

- Hire or company car? Some agreements need the owner's authorisation for the work, and sorting it before our engineers arrive is quicker than afterwards.

Ring 0333 366 0103 once you have got that ready — or, if the car is at home, going nowhere, use .

## Waiting for a fuel drain in Cappagh: what to do

Help, however well meant, is what does the damage whilst you wait. So hold to these.

- Your safety comes before your car. Somewhere unsafe? Get away from the traffic then wait away from it. Fine where it stands? Wait with it.

- No one — however helpful — starts it, whether to see if it runs or to shift the car a short way.

- No additives. Two-stroke oil, injector cleaner, something from the boot — none of that gets that petrol back out.

- A DIY drain misses your fuel already gone beyond your tank, and siphoning petrol by the road is hazardous too.

- Keep your ignition off — the windows and the radio too.

## The fuel drain, step by step, after the van arrives

- First, three queries: which fuel got in, the volume, and has it run? Those replies set the job, so our price follows them.

- Next the tank is drained, so the polluted fuel comes out.

- Petrol that has moved beyond your tank travels in your lines once it ran, and the fuel lines are purged to clear it.

- Cleared, or changed if the car has a serviceable one: the fuel filter is sorted next.

- Clean diesel in, and your system primed.

- The start-up. With clean diesel in and your system bled, it's started and tested to confirm it runs correctly.

Until it runs on new diesel, our technicians remain with it.

It's very unusual for a car caught soon to be left with long-term damage, and normal driving resumes straight away.

## Back on the road around Cappagh after your fuel drain

- Started on fresh diesel, it asks nothing special of you. Just drive normally.

- Give the first miles your attention. Smoke showing, a warning light coming on, your idle going lumpy or your throttle hesitating: pull over then ring us back.

- An insurer, a fleet manager or a hire company may ask what was carried out, so hold on to your paperwork.

- Next time, trust the pump's label instead of the colour of its handle.
