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

Whatever you do, don't switch the motor on, even for a moment, to move the vehicle. Stop; leave it off.

Cleared then flushed, right where it is: that is normally all an unrun diesel with petrol in it takes. Whether it remains that straightforward depends on the minutes to come more than on anything else.

From here on, step by step, for anywhere around Cloghy:

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

Work through the following first, in this order.

- Keys out of your ignition. Switching the ignition on can be all it takes to prime the system, while priming pulls petrol out of your tank toward the components it harms. Keep the vehicle off altogether.

- Topping up with diesel seems like it thins the problem. It does not: nothing comes out, and the tank simply carries more of the same.

- Hazards on. If you are anywhere 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, then roll it by hand — never under the engine, even for a few yards.

- Which fuel, and roughly how much? Your receipt replies both, and that is where our questions start. Don't bin it.

Still on the move when you realised? Come off the M77 at the next junction if that is where you are, over 50 miles from Cloghy, and pull over somewhere sensible instead of pressing on to the services. Then begin at stage one.

## Each Cloghy fuel drain starts here: has the motor run?

What comes after this turns on one answer, and only one.

Motor not run at all?

- That petrol is still in your tank and nowhere else.

- Draining and flushing, on the spot, is normally all of it.

- This is the best position to be in, and the reason step one counts.

Run at all, however briefly:

- Some petrol has left the tank already, passed through your filter, and reached your lines.

- The high-pressure fuel pump and the fuel injectors see it too on a longer run.

- The further it went, the larger this job — your lines, the fuel filter, and now and then more besides.

Petrol doesn't lubricate. Diesel does, protecting the high-pressure pump and injectors as it passes through, which is why the line falls where it does.

Nothing is harmed by petrol that is just resting in a tank.

The parts that shift it are grinding the moment petrol is being pumped.

## Cloghy, petrol in a diesel: have these prepared before you call

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

- BT22 1 and the remainder of the postcode is the best way to start telling us where you are.

- Wherever you have pulled up, the road's name helps — whether that is B7041 or somewhere else — and so does the name of a car park.

- Or the nearest landmark. A car park is easier to find by what it serves, like the one at the local shops.

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

- What went in. Petrol, or AdBlue. AdBlue is a different job with its own page for Cloghy, and so say which.

- Roughly how much — in litres from your receipt, or by how long the nozzle stayed in.

- If it has run, how far plus how hard — as well as whether it's run at all.

- The owner may have to authorise the work under some hire or company agreements — which is why it's faster to settle whose car it is before we arrive.

Next, 0333 366 0103. Not time-critical, the car left at home with nowhere to be? Then  will do as well.

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

The wait is where kindly meant help does the harm. Stick to these.

- Stay with the vehicle if it's safe where it is — but if it has stopped somewhere exposed, you come first: away from the traffic, waiting apart from it.

- Nobody starts it. Not a passer-by being helpful, not to check it is all right, not to roll the car a few yards.

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

- Siphoning petrol into a can at the roadside is risky — and it also leaves whatever fuel has already gone beyond your tank. Don't try a home-made drain.

- The ignition stays off. Even for the radio or your windows.

## Van arrived? The fuel drain, one stage at a time

- First, three questions: which fuel went in, the quantity, and has it run? Those answers set the job, and so our price follows them.

- Your tank is emptied. The tainted mixture comes out of your tank.

- The fuel lines are rinsed. If it ran, the petrol has moved beyond the tank, and the fuel lines are carrying it.

- Cleared, or replaced if the car has a workable one: your filter is sorted next.

- The fuel system is primed on clean diesel.

- First start on new diesel. Once bleeding is finished, your engine is fired up and our engineers confirm that it runs correctly.

Our engineers stay until it is running on new diesel.

Long-term damage is very uncommon when it has been caught soon, so your car can go straight back to normal driving.

## After your fuel drain: back on the road around Cloghy

- Once it has been started on clean fuel, there's nothing special to do: drive normally.

- Keep an eye on the first miles. A warning light, smoke, a rough idle or a flat spot under the throttle means pull over and call us back.

- Your documents covers the question a rental company, fleet manager or insurer may ask: what work was carried out. Keep it.

- Next time, read the petrol pump. The label, not the colour of its handle.
