# Lane End: Petrol in a Diesel Car? Here Is What Happens

Stop, and leave the motor off — not on, and not for a second to move it.

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

Below is the sequence from here, anywhere in Lane End you happen to be.

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

Before anything else, these — in this order.

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

- A fuller tank of the same mixture is all topping up leaves you, since it removes nothing. So no extra diesel.

- Visibility comes before the rest beside moving traffic: switch the hazards on, and only then think about everything else.

- Off the pump by hand. At a forecourt, get the staff to help you roll the vehicle clear of the petrol pump. Do not start it to shift it, however short the distance.

- The first question you will be asked is which fuel went in and about how much — and the till receipt shows both. Hold on to it.

If you were still driving when you realised, pull over somewhere sensible instead of pushing on for the services — on the M40, under a mile from Lane End, that means the next exit. Step one comes next.

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

Everything after this stage rests on one answer.

Not run, not even briefly:

- That petrol is still in that tank and nowhere else.

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

- Being here is the best case — which is the entire point of step one.

Engine run, however for a moment?

- Some petrol has left your tank already, passed through your filter, and got into your lines.

- On a longer run it has got to the high-pressure fuel pump and the injectors.

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

The reason the line falls there: diesel lubricates the high-pressure pump and the injectors as it passes through them, and petrol does not.

Nothing is damaged by petrol that's just sitting in a tank.

Petrol being pumped is wearing the components that shift the car.

## Before you call about petrol in a diesel in Lane End: what our engineers need

A little preparation is the difference between a van that finds you and a van that goes round.

- HP14 3 and the remainder of the postcode is the ideal way to begin telling us where you are.

- The road or the car park. A road name is a help — High Street, or wherever you have pulled up.

- Or the landmark. A car park is easier to find by what it serves, like the one at Asda.

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

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

- How much. Litres from the receipt, or how long the nozzle was in the filler.

- Whether it has run. Then if it has, how far plus how hard.

- Hire or company car? Some agreements want the owner's go-ahead for the work, and getting it before our technicians turn up is quicker than afterwards.

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

## While you wait for a fuel drain around Lane End

Help, however well meant, is what does the damage whilst you wait. So stick to these.

- Stay with the car if it's safe where it is — but if it has stopped somewhere unsafe, you come first: away from the traffic, waiting apart from it.

- Nobody — however helpful — starts it, whether to see if it runs or to move your car a short way.

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

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

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

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

- Our quote comes after three questions, not before them — what went in, how much, and if it has run — because those replies set the job.

- Clearing it's how that mixture gets taken from that tank.

- The fuel lines are cleaned. If it ran, the petrol has moved beyond the tank, and the fuel lines are carrying it.

- The fuel filter is sorted. Cleared, or swapped where your car has a serviceable one.

- Fresh diesel in, and the system primed.

- The first start on fresh diesel. When priming is complete, the motor is started and our engineers check that it runs smoothly.

Our engineers remain until it is running on clean diesel.

The car goes back to normal driving at once, and lasting damage is very rare when it has been spotted quickly.

## After your fuel drain is done: driving around Lane End again

- Nothing unusual is needed after a start with fresh diesel — normal driving is all.

- Watch the first miles. A warning light, smoke, a rough idle or a flat spot under your throttle means pull over and ring us back.

- The work may matter later with a hire firm, an insurer or a fleet manager. Hold on to the documents.

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