# What Happens Now: Petrol in a Diesel Car in Anna Valley

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

The next few minutes settle it far more than anything else: petrol in a diesel still unrun generally amounts to emptying then flushing, right there.

Here's the order of things from here, wherever you are around Anna Valley.

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

In this order, all before everything else:

- The keys out of the ignition. Switching the ignition on can be enough to prime the system, and priming draws petrol out of the tank towards the components it harms. Leave it off altogether.

- A fuller tank of the same mix is all topping up gives you, because it takes out nothing. So no extra diesel.

- Near moving traffic? Then your hazards go on before anything else, so the vehicle is easy to spot.

- Off the pump by hand. On a forecourt, get the staff to help you push the vehicle clear of the pump. Don't crank it to shift it, however short the way.

- Hold on to your receipt. It says which fuel was put in plus roughly how much, which is the first thing we'll ask.

If you were still driving when you realised, pull over somewhere safe instead of pushing on for the services — on the M3, under 15 miles from Anna Valley, that means the next junction. Stage one comes next.

## Anna Valley fuel drain: has the engine run yet, or not?

What happens after this rests on one answer, and just one.

If your motor hasn't run at all:

- Nowhere but your tank: that's where that petrol yet is.

- Normally it is drained and rinsed right where your car stands.

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

Engine run, even for a moment?

- Petrol has been drawn from that tank, through the filter and into the lines.

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

- Flushing the lines, your filter seen to, occasionally more: this job expands as the distance does.

Diesel keeps your high-pressure pump and the injectors protected as it runs through them. Petrol offers them nothing, and that's why the line is drawn there.

Nothing is damaged by petrol that's only resting in a tank.

The parts that move it are wearing the moment petrol is being pumped.

## Before you call about petrol in a diesel in Anna Valley: what we need

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

- SP11 7 plus the rest of the postcode makes the ideal way to begin telling us where you are.

- Name the road — White Oak Way or wherever you have pulled up — or the car park.

- Describe a car park by what it serves — the one outside McColls, for example — and it's far easier to find.

- The make and model of your car, and the fact it is a diesel.

- Petrol or AdBlue? Say which. They are different jobs, and AdBlue has its own Anna Valley page.

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

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

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

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

## Waiting for a fuel drain around Anna Valley: what to do

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

- Where the vehicle has stopped settles where you wait. Somewhere exposed: away from it, clear of the traffic. Safe: with it. Either way, safety ahead of the car.

- A kind passer-by does not start it. Nor does anyone wanting to check it still works, or moving it a couple of yards.

- Something from your boot, oil made for two-strokes or injector cleaner: no additive removes the petrol.

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

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

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

- First, three questions: which fuel got in, the quantity, and has it run? Those replies shape the job, so the quote follows them.

- Clearing it's how the blend gets taken out of your tank.

- Your lines are rinsed. If it ran, that petrol has shifted beyond your tank, and your lines are holding it.

- The fuel filter is dealt with. Cleared, or changed where the vehicle has a serviceable one.

- Clean diesel in, and the fuel system primed.

- The start-up. With fresh diesel in and the fuel system primed, it is started and checked to confirm it runs properly.

Only when it is running on clean diesel do our technicians head off.

Your car goes back to normal driving at once, and long-term damage is very rare when it has been noticed quickly.

## Back on the road in Anna Valley after your fuel drain

- Started on fresh diesel, it asks nothing unusual of you. Simply drive normally.

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

- An insurer, a fleet manager or a hire firm may ask what was carried out, so keep your paperwork.

- The handle's colour isn't the thing to go by next time — the label on the petrol pump is.
