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

Not for a moment, and not to move it: your motor remains off. Stop there.

Has not been run? Then petrol in a diesel will usually be a simple drain-and-flush job wherever your vehicle has stopped — and no other factor decides that as much as these next few minutes do.

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

## Motor off: minute one with petrol in a diesel

Before anything else, these — following this order.

- The keys out of the ignition. Turning your ignition on can be all it takes to prime the system, while priming pulls petrol out of your tank towards the components it harms. Keep the car off completely.

- Do not top it up with diesel. Adding diesel removes nothing. You are left with a bigger tank of the same mixture.

- Being seen comes before the rest beside moving traffic: put the hazards on, and only then deal with everything else.

- However short the way, starting it to move it is the mistake. On a forecourt, roll it clear of the petrol pump by hand instead, and ask the staff to lend a hand.

- Keep the receipt. It shows which fuel went in plus about how much, which is the first thing we'll ask.

On the M40, under 15 miles from Woodgreen, the next junction is the spot to come off; anywhere, the first safe place to stop. Don't press on to the services. Then go back to step one.

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

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

Not run, not even briefly:

- Just the tank has petrol in it so far.

- Where your car sits is usually where this work happens: a drain, then a flush.

- Stage one counts for precisely this reason: it's the best place to be in.

If it has been started, even for a second:

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

- A longer run takes it right through to the high-pressure pump and the injectors.

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

That line falls there since diesel lubricates your high-pressure pump and the injectors on its way through them — and petrol doesn't.

A tank of petrol, left alone, damages nothing.

Petrol being pumped is grinding down the parts that move it.

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

A little planning is the difference between a technician that finds you and a technician that goes round.

- The ideal start is a postcode — one beginning OX28 1 — for where you have stopped.

- Name the street — West End or wherever you have pulled up — or the car park.

- Car parks are found more easily by what they serve: say the one at Co-op Food, and it is simple.

- The car. Make, model, plus that it's a diesel.

- Which got in matters: AdBlue is a separate job from petrol, plus Woodgreen has a page for it. So tell us.

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

- The miles it covered, and how heavily, if it has run at all.

- The owner may have to approve this work under some hire or company contracts — so it is faster to settle whose vehicle it is before our technicians arrive.

Then ring 0333 366 0103. If it can wait — the car is at home with going nowhere —  does the trick as well.

## The wait for a Woodgreen fuel drain, and what to do in it

The wait is where well-meant help does the damage. Hold to these.

- Your safety comes before the car. Somewhere exposed? Get away from the traffic then wait away from it. Safe where it sits? Stay with it.

- No one starts it. Not a passer-by being helpful, not to check it is all right, not to roll the car a few yards.

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

- No home-made emptying. Siphoning petrol into a can by the kerbside is risky, and it leaves your fuel that has already gone beyond that tank.

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

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

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

- Emptying it is how that mixture gets taken from your tank.

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

- Cleaned, or changed if the vehicle has a usable one: the fuel filter is dealt with next.

- Fresh diesel in, and the fuel system primed.

- The start-up. With fresh diesel in and your system primed, it's started and checked to be sure it runs properly.

Only once it is running on fresh diesel do our engineers head off.

Your car goes back to normal driving at once, and permanent damage is very unusual when it has been spotted soon.

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

- Drive normally. There is nothing special to do after it has been started on fresh fuel.

- The first miles are the test. A warning lamp, exhaust smoke, a rough idle or a hesitant throttle is your signal to stop and ring us a second time.

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

- Read the label on the pump next time, not the colour of the handle.
