# The Next Steps, in Order: Petrol in a Diesel Car in Whiteway

Whatever you do, never switch your engine on, even for a moment, to move it. Stop; leave the car off.

Petrol in a diesel that hasn't been run is normally a simple drain and a flush, done where your car stands, and what happens in the coming few minutes determines that far more than anything else.

Anywhere you happen to be around Whiteway, here is how things run from now.

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

First, these — in this order.

- The ignition off, keys out. Turned on, the ignition can prime the system — and priming is what moves petrol out of the tank into the parts it damages.

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

- Get your car simple to see before anything else — hazards on — if there's traffic going past anywhere close to you.

- By hand, not under the engine: that's how it comes off the petrol pump. Ask the forecourt staff to help you roll, whatever the miles.

- Keep the receipt: the grade and roughly how much are printed on it, and they're what our engineers ask about first.

Realised on the move? Get off at the next exit if you are on the M4, under 10 miles from Whiteway, and pull over somewhere sensible — not at the services farther on. Stage one starts after that.

## The fork in every Whiteway fuel drain: has it run yet?

From this stage on, everything hinges on a single answer.

If the engine hasn't run at all:

- The petrol remains in that tank, and just there.

- Normally it is drained and rinsed just where the car is.

- This, here, is the best place to be in, and the whole reason stage one matters.

Motor run, even for a moment?

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

- Your high-pressure pump as well as the fuel injectors get it on a longer run.

- Lines flushed, the filter dealt with, occasionally more: this job expands as the miles does.

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

In your tank, left alone, petrol does no harm.

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

## Calling about petrol in a diesel from Whiteway: what to have ready

Whether the van circles or finds you depends on a little preparation.

- The best start is a postcode — one starting BA2 1 — for where you have stopped.

- Give the street — Mount Road or wherever you have stopped — or the car park.

- What a car park serves is the easiest way to find it, so say the landmark — such as the one at Co-op Food.

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

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

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

- If it's run, how far plus how heavily — and whether it's run at all.

- The owner may have to authorise the work under some hire and company agreements — so it's quicker to settle whose car it is before our technicians arrive.

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

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

Help, however well meant, is the thing that does the damage while you wait. So stick to these.

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

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

- Additives stay in the boot. Injector cleaner and two-stroke oil draw none of the petrol out again.

- Draining it yourself is out: a can of siphoned petrol on a verge is a danger, and the fuel beyond that tank stays put all the same.

- Even your radio or the windows aren't worth turning your ignition on for.

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

- Three queries. What was put in, how much, and whether it has run. The answers shape the job, which is why the price comes after them and not before.

- That tank is emptied. The tainted mixture comes from the tank.

- The fuel lines are purged. If it ran, that petrol has moved beyond that tank, and your lines are carrying it.

- Then your filter: replaced where there is a workable one, cleared where there's not.

- Clean diesel in, and the system primed.

- The start-up. With fresh diesel in and your system bled, it's started and tested to be sure it runs smoothly.

We wait until it is running on new diesel.

If it has been noticed quickly, permanent damage is very rare, and the car goes back to normal driving at once.

## Once the fuel drain is done: driving in Whiteway again

- Nothing unusual is needed after a start with fresh diesel — usual driving will do.

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

- Your documents answers the query a rental company, fleet manager or insurer may ask: what work was carried out. File it.

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