# Crofton: AdBlue in the Diesel Tank? Leave It Off

With AdBlue in the diesel tank, your ignition remains off and so does your engine.

Chemically, AdBlue is simply urea in water.

It doesn't burn, it doesn't mix with diesel, and the damage it does starts when your fuel system draws it in.

If the engine hasn't run yet, AdBlue in a diesel tank is normally drained and carefully flushed where the car sits around Crofton.

No step comes before calling 0333 366 0103.

## Your next steps straight away, Crofton: AdBlue in your diesel tank

Do these:

- Pull your keys out, so no one switches the ignition on.

- Hazards on, if moving traffic is at all close.

- So you can tell us which fluid it was and about how much, save the receipt or the empty bottle.

- Call us from where you are. A postcode starting WF4 1, or the name of the closest street, brings the van to you without a search.

Do not do these:

- Shifting the car even a short way is no reason to fire up the engine.

- Plenty of diesels power their fuel pump the instant your ignition goes on, so leave the car off.

- Pouring in more diesel doesn't work: AdBlue separates out rather than blending.

- Any driving at all is to be avoided, including a short stretch along High Street.

- No draining it yourself, either, at the roadside.

At a forecourt around Crofton, whether it is the JET or another one, ask the attendants to help you roll the vehicle clear of the pump.

On that drive, the vehicle remains exactly as it was left.

## What does AdBlue do in a diesel tank?

The engine is not what AdBlue is made for; your exhaust is.

It goes into its own tank and is sprayed into the exhaust gas to fresh it.

A fuel pump is not made to take it, and AdBlue was never intended to travel through one.

Poured in with your diesel, it stays separate rather than mixing — quite different from fuel.

The pickup sucks fuel from the deepest part of that tank, and that is exactly where AdBlue settles: as it is heavier than diesel, it sinks.

The first thing the system pulls through, once it runs, is the AdBlue. So a motor that had AdBlue poured in on a drive in Foulby last night, and hasn't been started since, is still the simple case: the AdBlue is lying at the bottom of that tank, and nothing has pulled it in.

Two kinds of harm follow from there.

It attacks certain metals found in fuel systems, working on whatever it reaches until it is cleared completely. And once the water evaporates, the urea turns into crystals that block filters and settle in tiny channels.

A car left standing in Crofton with AdBlue already in its lines is worse by the morning; one with AdBlue only in its tank isn't.

Water lubricates nothing. The high-pressure pump and each injector need diesel running through them, so the water part harms them in its own right.

## Why AdBlue in a diesel is regularly more major than petrol

Put petrol in a diesel at the Shell and you have a fault of thin fuel.

It mixes with the diesel, and while it is in your tank it does no harm; the damage comes from running your motor on it.

The issue with AdBlue in a diesel is a totally unsuitable substance.

Not burning, it cannot simply be run through.

Whether your car sits in Wintersett or the heart of Crofton, firing it up "to see" does more harm in this case than almost any other slip, and the flush matters more. The reasons: it won't remain mixed, so diluting it is impossible; and crystals and corrosion outlast the next tankful.

As with petrol, there's good news.

Never started? Then the AdBlue sits only inside your tank, the easiest bit of the entire system to empty, anywhere the car has come to rest in West Yorkshire.

## How does AdBlue end up in a diesel tank around Crofton?

It is not deliberate. Plenty of vehicles keep the AdBlue cap alongside the diesel inlet, occasionally under a single flap, and muddling them up is easy after dark.

It mostly happens at home, from a bottle bought en route home, rather than at the forecourt.

A couple of familiar ways cover most cases.

The top-up is rushed outside Crofton Infant School, after the dash lit up with a warning as the children were dropped in.

After work, a bottle is tipped in on a driveway close to Smithy Close.

One more pattern: dim light, a pub car park outside The Royal Oak, and someone using that flap for the first time.

It comes up the most in a hire car, a brand-new car, a fleet car, or the other vehicle of a family with both fuels — the vehicles people know the least.

An identical slip, same first step — leave it switched off — anywhere you are in Crofton or the remainder of West Yorkshire.

## Crofton: started the motor with AdBlue in the diesel tank?

Then your tank is no longer where the AdBlue is.

The filter and lines have had it sucked through, and any running time takes it on to the high-pressure pump and every injector.

Watch for rough running, exhaust smoke, falling power, warnings on the dash, or a cut-out — returning from The Sidings, say, or midway across Crofton.

Once safe, pull over then turn everything off — with no restarting to test.

Every start pulls more of that through.

If you were on the M62, under 5 miles from Crofton, come off at the next exit and stop somewhere safe rather than pressing on.

Every mile pushes the AdBlue deeper into your system. That is why a hop across Crofton to park near Crofton Young People's Centre and a drive of under 5 miles towards Wakefield are very distinct jobs.

Let us know about how far it had come.

Wherever the car came to a stop is where all of it gets done, even with more to flush once the motor has been run.

Very rarely does it leave lasting damage when it's caught quickly.

## Emptying AdBlue in a diesel around Crofton: what it takes

Wherever it has stopped around Crofton — a forecourt, a layby, a driveway, a road beside All Saints’ Church — our van travels to the vehicle.

Three replies shape the job, so first we ask what went in, about the amount, plus if your motor has run.

Right there, the tank is then emptied, and both the polluted diesel and the urea come out as one.

The fuel system is cleaned thoroughly, which matters more with AdBlue than with petrol, because what it leaves behind does not rinse out on its own.

Fresh diesel goes in once the fuel filter is cleaned — or swapped, if it needs to be — and after that the car is tested.

Roughly half an hour on site is typical for most jobs where the motor has not run.

Low-noise enough to use outside a house at night, and fine on a working forecourt, the pumps are explosion-proof.

Priming the system with new diesel comes at the end.

Whether it's a parking bay at Streethouse or a driveway in Crofton, that is where we start it and you set off.

Before we go, our technicians check it's running properly with new diesel in.

We do it all wherever the car has stopped, and it never needs to go to a garage.

At the end, you are given the paperwork for the insurer: a VAT invoice and a written report from the engineer.

## About Crofton

Crofton is a village in West Yorkshire, situated approximately 3.4 miles from Wakefield, and is characterized by its semi-detached housing stock. Crofton sits inland at an elevation of around 66 metres, within a short distance of nearby places such as New Crofton and Sharlston. Crofton has a population of around 2415 residents, and is located near Sharlston Common. Crofton is positioned roughly 158 miles north of London.

## AdBlue drains across West Yorkshire, Crofton included

New Crofton, Sharlston Common and Sharlston are among the towns around Crofton that the same vans serve, along with most of West Yorkshire beyond, throughout the WF postcode area.

Phone and check rather than guess if you're by a border, or anywhere awkward to pin down.

A van that comes to you suits Crofton, a rural village: there's no need to bring the vehicle to us, because our technicians empty it on the spot, in a drive, a side street, a car park or a filling station.

## What AdBlue in a diesel tank costs to put right in Crofton

Since each callouts differ, a single price would not be fair.

The price moves first with how long, if at all, your engine has been running, and next with the amount of AdBlue that got in. After that it depends on where your car is and whether our van can reach it safely, which is easier on an open drive than in a tight gap behind St Joseph's.

Ahead of any quote, never after, every enquiry from Crofton opens with three questions: the fuel, the quantity, and whether the engine ran.

Those replies turn a range into a straight quote.

You hear that price on the phone, before anyone heads out, and you pay on the day, by card or by phone, with nothing upfront.

As our engineer is on the way, dig out your insurance: plenty include misfuelling.

## Still alongside the car in Crofton?

Not touching your car is, right now, the most useful thing open to you.

Ignition off, motor off, keys out.

Petrol in Diesel takes over the rest, in Crofton or anywhere within West Yorkshire, once you call 0333 366 0103 saying it's AdBlue, roughly how big an amount, and whether it ran.
