# AdBlue in a Diesel Tank in Parkgate? Don't Start It

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

AdBlue is urea dissolved in water.

The trouble begins once it's sucked through the lines — it will not burn, and it will not blend with diesel.

Caught before your motor has been run, AdBlue in a diesel tank is usually a drain and a thorough flush, done where your car is around Parkgate.

First, phone us on 0333 366 0103.

## AdBlue in the diesel tank in Parkgate: the first few minutes

Things to do:

- Keys out — then no one can switch anything on.

- If you're at all close to moving traffic, put your hazards on.

- The empty bottle or the receipt tells us the product and the amount, and so don't throw it away.

- Call just where you are. Quote a CH64 6 postcode or the nearest street name, and no one has to hunt for you.

Things not to do:

- Not even briefly, and not to roll the vehicle: the motor remains off.

- Turning the key to ignition alone starts the pump running on many diesels. Avoid it.

- Do not top up with diesel to thin it. AdBlue does not dilute in diesel; it separates out.

- Do not drive it anywhere, not even a short stretch up The Parade.

- No emptying it yourself, at all, on the roadside.

Get the attendants to help you move the vehicle off the pumps if you are at a forecourt in Parkgate, whether it is the Shell or somewhere else.

If you're on your own drive, leave it exactly where it is.

## What AdBlue does in a diesel tank

Not the motor but your exhaust is where AdBlue is meant to go.

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

Nothing inside a fuel pump is made for this fluid — and no part of it was intended to go that way.

Inside a diesel tank it acts very differently from fuel. It doesn't mix in.

The pickup sucks fuel from the deepest part of that tank, and that is just where AdBlue ends up: being heavier than diesel, it sinks.

A vehicle filled on a drive in Gayton yesterday evening and left unstarted counts as the straightforward one. No pump has pulled the AdBlue up yet — but once the engine turns, that is what goes first, directly from the bottom of that tank.

It does two kinds of damage from there.

Crystals and corrosion. As the water evaporates, it leaves urea that crystallises in filters and narrow channels; meanwhile, since it eats at certain metals, each part it reaches suffers for as long as it stays inside.

Overnight, a car sitting around Parkgate with AdBlue through its pipework grows worse; if it is only in the tank, nothing changes.

The water in it does damage of its own: the high-pressure pump and the fuel injectors rely on diesel to lubricate them, and water offers them nothing.

## Why is AdBlue in a diesel often the bigger fault?

A problem of thin fuel is what you end up with from fuelling a diesel with petrol at the Texaco.

Mixed through your diesel and sitting unused, it's no threat at that stage; running your engine does the damage.

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

It does not burn, so it cannot simply be run through.

It does not stay mixed, so it cannot be diluted. And crystals and corrosion don't wash out with the next tank of fuel. That is why the flush counts more with AdBlue than with petrol, and why starting the engine "to see" costs more here than nearly anywhere else, whether the vehicle is in Hinderton or the middle of Parkgate.

As with petrol, there's good news.

Never run? Then the AdBlue sits just inside the tank, the simplest section of the entire system to clear, wherever your car has stopped in Cheshire.

## Parkgate: how AdBlue ends up in a diesel tank

No one means to do it. The AdBlue filler on plenty of motors sits right next to the diesel filler, sometimes under the same flap, and the two caps can look alike in poor light.

Mostly it happens with a bottle bought on the way home and poured in on the driveway, not at the pump.

The ways it takes place are few and familiar.

The refill is hurried outside Parkgate Primary School, because your dash lit up with a warning as the kids were dropped off.

A driver pours the bottle in outside their house, just off Mostyn Square, as the day ends.

Or your car is topped up in the car park outside The Red Lion, in poor light, by a person who has never opened that flap before.

Hired cars, new vehicles, company motors, or the second car in a family with one of each: the least known vehicles see it most.

Wherever in Cheshire, Parkgate included, the mistake doesn't change, and nor does the first step: leave it off.

## Started the motor with AdBlue in your diesel tank in Parkgate?

In that case, the AdBlue is no longer inside the tank.

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

Rough running, smoke, dropping power, dashboard lights or stalling: each might appear, perhaps part way across Parkgate or coming back from The Donkey Stand.

No restarting to check: stop once safe, then switch it off.

Each start pulls more of that through.

Leave the M53, under 5 miles from Parkgate, by the next junction and park safely, not driving on.

Mileage counts: each mile pushes the AdBlue deeper into the system, so driving for Liverpool, under 10 miles away, gives a far bigger job than hopping across Parkgate to the car park by The Peters Family.

Tell us roughly how far it had come.

Wherever your car came to a halt is where all of it gets done, even with more to rinse out once the engine has been started.

Lasting damage is very unusual when it is caught soon.

## What does an AdBlue drain on a diesel involve in Parkgate?

A street by Irene Prosser, a drive, a lay-by or a filling station: wherever your car has stopped in Parkgate, our technicians come to it.

Which fluid went in, about the quantity, plus if your motor has turned over: we ask first, since those shape the work.

On the spot, that tank is then drained, and both the contaminated diesel and the urea come out at once.

With AdBlue, far more than with petrol, flushing counts: the whole system is flushed right through since what remains won't flush away by itself.

Clean diesel goes in after the fuel filter is flushed — or replaced, if it needs to be — and after that your car is tested.

The majority of these jobs are a half-hour job once we get there, provided your motor has not run.

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

Fresh diesel goes in to prime the system, and that's the last step.

Whether it is a parking bay at Neston or a drive around Parkgate, that is where our technicians start the car and you drive off.

The test before we go is that it runs smoothly on new diesel.

The whole job is done where your car is, so it never needs to be taken to a garage.

Insurers ask for a VAT invoice and an engineer report, and you get both afterwards.

## About Parkgate

Parkgate is a coastal suburban area in Cheshire, situated near the Dee Estuary and close to the Welsh border. Parkgate has a low elevation of around 9 metres above sea level and is located near the towns of Neston and Little Neston. Parkgate is characterised by its predominantly detached housing stock and is within commuting distance of Liverpool, which is approximately 9 miles away. Parkgate is also relatively distant from London, at around 175.5 miles away.

## AdBlue drains across Parkgate and Cheshire

Our vans that answer AdBlue jobs around Parkgate also cover the spots about it, Moorside, Neston and Little Neston among them, and most of Cheshire beyond, across the CH postcode area.

Near a border, or anywhere tricky to pin down? Asking beats assuming, so ring.

No towing is needed. In Parkgate, a residential suburb, a van that comes to you works: the car is drained on the spot, be it on a drive, a residential street, a car park or a forecourt.

## What does AdBlue in a diesel tank cost to sort out around Parkgate?

Since the jobs vary, a single price wouldn't be honest.

What moves the price is, first of all, whether your engine has run and for how long; then how much AdBlue was put in; and after that where the car is and whether a technician can reach it safely, which is simpler on an open drive than in a tight gap behind Philip Owen.

Ahead of any figure, not afterwards, each enquiry from Parkgate begins with the same three checks: the liquid, the quantity, and whether the engine ran.

The replies turn a range into a straight quote.

Quoted on the call before the engineer heads out, the job is paid for on the day — card or phone, nothing in advance.

Plenty of insurance policies include misfuelling cover, so it's worth checking yours whilst we are on the way.

## In Parkgate and still next to your car?

Leaving the vehicle alone is, then, the best move you can do.

Keys out; engine and ignition off.

Call 0333 366 0103 and tell us it is AdBlue, roughly how much, and if it's run. Petrol in Diesel takes it from there, in Parkgate or anywhere across Cheshire.
