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

Whatever you do, never switch your engine on, even briefly, to move it. Stop; leave the vehicle off.

Cleared and flushed, right where it sits: that's normally all an unrun diesel with petrol in it needs. Whether it remains that straightforward rests on the minutes ahead more than on anything else.

Here is the sequence of things from now, anywhere you are in Leazes.

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

Before anything else, the following — following this order.

- Keys out of the ignition. Turning your ignition on can be all it takes to prime the system, while priming draws petrol out of your tank towards the parts it harms. Keep it off completely.

- Topping up with diesel sounds like it dilutes the issue. It doesn't: nothing gets out, and your tank simply carries more of the same.

- Hazard lights on. If you are at all close to moving traffic, make your car easy to see before you do anything else.

- Off the pump by hand. At a forecourt, get the attendants to help you push it clear of the pump. Do not start it to shift it, however short the way.

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

Noticed on the move? Get off at the next exit if you are on the A1(M), under 10 miles from Leazes, and pull over somewhere safe — not at the services farther on. Step one starts after that.

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

From this point on, everything comes down to a single answer.

If it has never been started:

- Just that tank has petrol in it so far.

- Where the vehicle stands is normally where the work is done: a drain, then a flush.

- This is as good as it gets — which is the entire point of step one.

If it's been started, even for a moment:

- Out of that tank, past the filter, into the lines: that is how far the petrol has travelled.

- Run it farther and the petrol gets to the injectors, having gone through the fuel pump first.

- The farther it went, the bigger the job — the fuel lines, your filter, and sometimes more besides.

The reason the line falls there: diesel protects the high-pressure fuel pump and the injectors as it flows through them, and petrol does not.

Petrol resting in a tank harms nothing.

Pump that petrol, though, and it wears the very parts doing the moving.

## Before you call about petrol in a diesel in Leazes: what our engineers need

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

- Where you are. A postcode starting NE16 6 is the best start.

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

- Name a car park by what it serves — the one outside Co-op Food, for instance — and it's much quicker to find.

- The vehicle. Make, model, and that it is a diesel.

- Which went in counts: AdBlue is a separate job from petrol, and Leazes has a page just for that. So tell us.

- How long the nozzle was in, or the litres from the receipt — either tells us how much.

- Has it run? If so, say how far it went, and how it was driven.

- Hire or company car? Some contracts want the owner's authorisation for the work, and sorting it before we arrive is quicker than afterwards.

Call 0333 366 0103 once you've got that together — or, if the vehicle is at home, going nowhere, use .

## Waiting for a fuel drain around Leazes: what to do

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

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

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

- None of that gets the petrol back out — not two-stroke oil, not injector cleaner, not something from the boot. So no additives.

- Draining it yourself is not the answer: a can of siphoned petrol on a verge is a danger, and your fuel beyond your tank stays put regardless.

- Even your radio or your windows are not worth turning your ignition on for.

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

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

- Your tank is emptied. The contaminated mix comes out of your tank.

- If it ran, your lines are holding petrol that has shifted beyond your tank — so they are rinsed.

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

- Fresh diesel goes in, then the system is primed.

- We start the car only after clean diesel has gone in and bled your system, then make sure that it is running properly.

Only when it's running on clean diesel do we go.

If it has been spotted soon, lasting damage is very uncommon, and the car returns to normal use straight away.

## Back on the road in Leazes after your fuel drain

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

- Pull over and call us back if anything seems wrong early on — a light on the dash, smoke from the exhaust, an idle that is lumpy, or a throttle with a dead spot.

- The paperwork covers the query a rental company, fleet manager or insurer may ask: what work was carried out. File it.

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