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

Stop, then leave your engine off — not on, and not for a second to move the car.

The next few minutes decide it more than anything else: petrol in a diesel still unrun normally comes down to emptying then purging, right there.

What follows is the order from this point, anywhere in Whitley you are.

## Petrol in a diesel? What to do in minute one

Go through these in order, before you do anything else.

- Keys out of your ignition. Turning your ignition on can be enough to prime your fuel system, and priming draws petrol out of your tank toward the components it harms. Keep the car off completely.

- No diesel on top. More fuel in takes away none of the petrol — it just leaves you with more of the same blend.

- Hazards on. If you're at all near moving traffic, make the vehicle easy to see before you do anything else.

- The attendants will normally help you push it away from the petrol pump. Ask, then roll it by hand — never on the motor, even for a few yards.

- Hold on to your receipt: the fuel and roughly how much are printed on it, and they are what our engineers ask for first.

On the M6, under 3 miles from Whitley, the next exit is the location to leave it; elsewhere, the first safe location to stop. Don't push on to the services. Then go back to step one.

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

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

Not run, not even once:

- Nowhere but the tank: that is where that petrol yet is.

- Normally it is drained and purged right where the car is.

- This is the best spot to be in, and the whole reason step one matters.

Motor run, even briefly?

- From your tank, past the filter, into the lines: that's how far that petrol has travelled.

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

- Lines flushed, your filter sorted, and sometimes more: this job expands as the distance does.

The reason the line falls there: diesel protects the high-pressure pump and the injectors as it flows through them, and petrol doesn't.

A tank of petrol, left alone, hurts nothing.

As soon as it's pumped, petrol starts wearing down whatever moves it.

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

A little planning is the difference between a van that finds you and a van that circles.

- Your location: a postcode beginning WN1 2 serves best.

- A road name helps: Whitley Crescent, say, or whichever street you've stopped in. A car park does the trick too.

- Car parks are located more easily by what they serve: say the one at Tesco Extra, and it is straightforward.

- That it's a diesel, plus the make and model of the car.

- Petrol or AdBlue? Say which. They are different jobs, and AdBlue has a separate Whitley page.

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

- The mileage it covered, and how heavily, if it ran at all.

- Whose motor it is. Some hire or company contracts want the owner to approve this work, and that is easier settled before our engineers get there than after.

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

## Whitley fuel drain on its way? Whilst you wait

Stick to these: well-meant help causes the harm during the wait.

- Your safety comes before your car. Somewhere exposed? Get clear of the traffic and wait away from it. Fine where it sits? Wait with it.

- Not to roll it a few yards, not to check it is all right, not as a passer-by's favour: no one starts it.

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

- Emptying it yourself is out: a can of siphoned petrol on a verge is a danger, and the fuel beyond your tank stays put regardless.

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

## The fuel drain, step by step, once our van arrives

- Three queries. What went in, how much, and if it's run. Those answers decide the job, which is why the quote comes after them but not before.

- Draining it's how the mixture gets taken from the tank.

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

- Cleaned, or swapped if the car has a usable one: your filter is seen to next.

- Clean diesel in, and the fuel system primed.

- The start. With new diesel in and the fuel system bled, it's fired up and checked to make sure it runs properly.

Only when it's running on new diesel do our engineers head off.

It is very rare for a vehicle caught quickly to be left with long-term damage, and normal driving resumes right away.

## After the fuel drain: back on the road around Whitley

- Drive normally. There's nothing unusual to do after it's been started on fresh fuel.

- 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 work may come up later with a hire company, an insurer or a fleet manager. Keep the paperwork.

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