# Lower Fold: Petrol in a Diesel Car? Here Is What Happens

Pause, then keep the motor off — not on, and not for a moment to move the vehicle.

Hasn't been run? Then petrol in a diesel tends to be a simple drain-and-flush job wherever the vehicle has stopped — and no other factor settles that more than the next few minutes do.

What follows is the order from this point, wherever in Lower Fold you happen to be.

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

Do these before anything else, in this order.

- The ignition off, keys out. Switched on, the ignition can prime your system — and priming is what draws petrol out of your tank into the parts it harms.

- A bigger tank of the same mixture is all topping up leaves you, because it takes out nothing. So no more diesel.

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

- Off the petrol pump by hand. At a forecourt, ask the staff to help you push it away from the pump. Do not fire it up to move it, however short the way.

- Keep your receipt: the grade and the rough amount are printed on it, and they are what our engineers ask for first.

Noticed on the move? Get off at the next exit if you're on the M65, under 3 miles from Lower Fold, and pull over somewhere safe — not at the services further on. Step one comes after that.

## The fork in each Lower Fold fuel drain: has it run yet?

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

If the motor hasn't run at all:

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

- The work is a simple drain and a flush, normally done where the vehicle is.

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

If your motor has run, even for a moment:

- The fuel lines and the filter already carry petrol drawn from the tank.

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

- The job expands with the distance — lines purged, filter seen to, occasionally more.

That line falls there since diesel lubricates the high-pressure fuel pump and the fuel injectors on its way through them — and petrol does not.

Petrol resting in a tank harms nothing.

Petrol being pumped is grinding down the components that shift it.

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

A van that circles versus a technician that finds you: a little preparation is the difference.

- Your whereabouts: a postcode starting BB6 7 serves best.

- A road name helps: Lowerfold Road, say, or whatever street you have stopped in. A car park works too.

- Car parks are located most easily by what they serve: tell us the one at Morrisons, and it's simple.

- The vehicle. Make, model, and that it is a diesel.

- Petrol or AdBlue? Tell us which. They are different jobs, and AdBlue has its own Lower Fold page.

- The amount: your receipt's litres, or otherwise how long you had the nozzle in.

- If it has run, how far plus how heavily — as well as if it has run at all.

- The owner may have to approve the work under some hire and company agreements — which is why it is quicker to settle whose car it is before our engineers arrive.

Then call 0333 366 0103. If it can wait — the car is at home and going nowhere —  works too.

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

Hold to these: kindly meant help does the harm during the wait.

- Your safety comes before the car. Somewhere unsafe? Get clear of the traffic then wait away from it. Fine where it stands? Stay with it.

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

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

- Clearing it yourself is out: a can of siphoned petrol on a verge is a danger, and your fuel beyond your tank stays put anyway.

- Ignition remains off. Even for the radio or the windows.

## When our van gets there: your fuel drain, step by step

- Three questions. What got in, how much, and if it has run. Those answers shape the job, which is why our quote comes after them and not before.

- Then your tank is emptied, so the tainted fuel is taken out.

- Your lines are cleaned. If it ran, the petrol has moved beyond your tank, and your lines are holding it.

- Cleaned, or changed if your car has a workable one: your filter is seen to next.

- Bleeding the system follows after fresh diesel is in.

- The first start on clean diesel. Once bleeding is complete, the engine is started and our engineers check that it runs correctly.

The vehicle has new diesel running through it before our technicians head off.

It is very uncommon for a vehicle noticed early to be left with long-term damage, and normal driving starts again at once.

## Back on the road around Lower Fold after the fuel drain

- Drive normally. There's nothing special to do after it has been started on clean fuel.

- The first miles are the test. A dash warning, exhaust smoke, a rough idle or a flat throttle is your cue to stop then ring us again.

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

- Next time, read the pump. The label, not the colour of its handle.

## Leave it off and ring: petrol in a diesel across Lancashire

Petrol in Diesel takes it from there — on your driveway, at the roadside, on the forecourt — once you've done step one: keys out, engine off, receipt in your pocket.
