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

Stop, then keep the motor off — not on, and not for a moment to shift the car.

Cleared then purged, right where it sits: that is usually all an unrun diesel with petrol in it needs. Whether it remains that straightforward depends on the minutes ahead more than on everything else.

Here's the sequence of things from now, anywhere you're in Childwall.

## Minute one: petrol in a diesel, engine off

Before anything else, the following — in this order.

- Take the keys out. Even the ignition by itself can prime the fuel system, pulling petrol out of the tank to precisely the components it harms, and so keep the vehicle off completely.

- No diesel on top. More fuel in takes away none of that petrol — it only makes you with more of the same mixture.

- Make your car simple to see before anything else — hazards on — if there's moving traffic anywhere near you.

- Off the petrol pump by hand. At a forecourt, ask the staff to help you push the car clear of the pump. Don't start the car to shift it, however short the distance.

- Which fuel, and about how much? Your receipt answers both, and that's where our questions start. Don't bin it.

If you were still driving when you noticed, pull over somewhere safe instead of pushing on for the services — on the M62, under a mile from Childwall, that means the next junction. Step one comes next.

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

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

Motor not run at all?

- No place but that tank: that's where the petrol yet is.

- The job is a simple drain and a flush, normally done where the car is.

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

If the engine has been run, even briefly:

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

- On a bigger run it has reached the high-pressure fuel pump as well as your injectors.

- Miles is what makes it a larger job: flushed lines, a filter seen to, and at times more than that.

Petrol does not lubricate. Diesel does, protecting the high-pressure pump and injectors as it flows through, which is why the line sits where it does.

Nothing is harmed by petrol that is just sitting in a tank.

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

## Calling about petrol in a diesel from Childwall: what to have prepared

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

- Where you are. A postcode beginning L16 5 is the best start.

- The road or the car park. A road name helps — Childwall Lane, or wherever you have pulled up.

- Or the landmark. A car park is quicker to find by what it serves, such as the one at Aldi.

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

- Say which got in — petrol or AdBlue — because AdBlue is a different job, with a page of its own for Childwall.

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

- The mileage it did, and how heavily, if it has run at all.

- Sort who owns the vehicle before we arrive: some hire and company agreements want the owner to authorise the work, and doing it faster first.

Next, 0333 366 0103. Not time-critical, the vehicle parked at home with nowhere to be? Then  works too.

## Whilst you wait for a fuel drain around Childwall

The wait is where well-meant help does the damage. Hold 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 before the car.

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

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

- Siphoning petrol into a can by the kerbside is hazardous — and it still leaves whatever fuel has already gone beyond the tank. Don't drain the car yourself.

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

## Step by step: the fuel drain when the van arrives

- Our quote comes after three questions, not before them — what went in, how much, and whether it's run — since the answers set this job.

- The tank is drained. The tainted blend comes out of the tank.

- Petrol that has moved beyond your tank sits in the lines once it ran, and the fuel lines are rinsed to shift it.

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

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

- First start on fresh diesel. When bleeding is finished, your engine is fired up and we confirm that it runs smoothly.

Our engineers stay until it is running on clean diesel.

If it has been noticed early, long-term damage is very rare, and your car goes back to normal driving right away.

## Childwall, after your fuel drain: back on the road

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

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

- Keep your documents. A hire firm, a fleet manager or an insurer may ask what was done.

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