# High Friarside: AdBlue in the Diesel Tank? Leave It Off

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

Chemically, AdBlue is just urea in water.

Being water-based, it will not ignite and never combines with diesel; trouble just starts once the pump begins pulling it.

Caught before the engine has run, AdBlue in a diesel tank is generally a drain and a thorough flush, done where the car is in High Friarside.

First, phone us on 0333 366 0103.

## AdBlue in your diesel tank in High Friarside: the first few minutes

Do these:

- Take your keys out, and so nobody switches your ignition on.

- If you're anywhere near moving traffic, put the hazard lights on.

- Which fluid, and roughly how much quantity? Save the bottle or your receipt, and we can see.

- Call right where you are. Say a NE16 6 postcode or the nearest street name, and no one has to search for you.

Not to do:

- Do not start your motor, even for a moment to shift your car.

- Turning the key to ignition by itself starts your pump running on many diesels. Skip it.

- No more fuel added. The AdBlue won't blend, so it is pointless.

- Even a short way along Briardene is too far to drive the car.

- No emptying it yourself, either, on the roadside.

The attendants working at any High Friarside forecourt — the Esso among them — will normally lend a hand pushing it aside if you ask.

If you are on your own drive, leave the vehicle exactly where it is.

## What does AdBlue do in a diesel tank?

Meant for the exhaust, AdBlue has no business in your motor.

Kept in a separate tank, it's squirted into the exhaust stream to clean the gases.

Nothing in it is supposed to pass through a fuel pump, and nothing in a fuel pump is made to handle it.

It doesn't blend. After it is tipped into a tank of diesel, AdBlue behaves nothing like fuel.

It's heavier than diesel, so it sinks and gathers at the bottom of that tank, which is where the pickup draws fuel from.

Simplest of all: one that got AdBlue in Pickering Nook overnight and has not been started since. The AdBlue waits at the foot of your tank, untouched — though it would be the first thing through once your engine runs, before any diesel at all.

It does two kinds of harm from there.

What remains once the water goes is urea, which forms crystals: they settle in tiny channels and block filters. On top of that, it attacks certain metals in a fuel system, and keeps going until it's cleared out.

A car left sitting around High Friarside with AdBlue already in its lines is worse by the morning; one with AdBlue only in its tank is not.

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

## AdBlue in a diesel: why it's commonly worse than petrol

An issue of thinned fuel is what you get after fuelling a diesel with petrol from the Texaco.

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

AdBlue in a diesel is a fault of the wrong substance altogether.

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

It does not stay mixed, so it cannot be thinned. And crystals and corrosion do not wash out with the next tank of fuel. That's why the flush matters more with AdBlue than with petrol, and why starting your motor "to see" costs more here than nearly anywhere else, whether your car is in Lintzford or the middle of High Friarside.

The same good news holds as with petrol.

Never started? Then the AdBlue sits only inside your tank, the simplest section of the whole system to empty, wherever your car has come to rest across Durham.

## AdBlue in a diesel tank in High Friarside: how it ends up there

Many vehicles place the AdBlue cap beside the diesel one, now and then under one flap, and after dark the two may appear the same. Nobody intends it.

It usually takes place outside the house, from a bottle grabbed en route home, not at the forecourt.

The ways it takes place are few and familiar.

Halfway through the morning drop-off, the dashboard flags it up, and outside Burnopfield Primary School the top-up is rushed.

Close to Front Street, a driver tips a bottle in at home in the evening.

Another pattern: darkness, the car park outside The Sun Inn, and someone using that flap for the first time.

It occurs most in the vehicles people know least: a hire car, a new car, a company car, or the second motor of a household with one diesel and one petrol.

Wherever around Durham, High Friarside included, the mistake doesn't change, and nor does the first response: keep it off.

## Already started your engine with AdBlue in your diesel tank around High Friarside?

If so, the AdBlue is no longer in the tank.

It has been pulled through the filter and your lines, and if your engine ran for any time, it has reached the high-pressure pump and the fuel injectors.

Lumpy running, smoke, dropping power, dashboard warnings or stalling: any might appear, perhaps part way across High Friarside or returning from Black Hill.

Once safe, pull over and switch everything off — with no turning it on again to see.

Each start pulls more of that through.

Leave the A1(M), under 10 miles from High Friarside, at the first junction and park safely, not driving on.

Mileage matters: every mile carries the AdBlue further in, and so driving towards Newcastle upon Tyne, under 10 miles away, makes a much bigger job than crossing High Friarside to the car park by Lintz Cricket Club.

About how far it had come is worth telling us.

Once the engine has run, the flush takes in more, and all of it is done where the vehicle has come to a stop.

Very seldom does it leave permanent damage if it is caught soon.

## Emptying AdBlue in a diesel in High Friarside: what it takes

Anywhere it has come to rest in High Friarside — a forecourt, a layby, a drive, a street beside St James — our van comes to the car.

The job depends on three replies, which our engineers ask for before all else — which fluid was put in, the quantity, and whether your engine has turned over.

Next, emptying that tank right there takes out the contaminated diesel and the AdBlue together.

Your system is flushed thoroughly, which counts more with AdBlue than with petrol, since what it leaves behind doesn't rinse out on its own.

After that, the fuel filter: cleaned, or changed if it has to be. Then fresh diesel, then a check of your car.

Engine not run? In that case count on about half an hour on site for most jobs.

Explosion-proof pumps make a live forecourt sensible to work on, and they're quiet enough not to disturb the street at night.

Bleeding the fuel system with new diesel comes at the end.

Starting it comes next, and then you drive off from where your car is parked, outside Blaydon or on a driveway around High Friarside.

The check before our engineers go is that it runs smoothly on clean diesel.

No garage is needed at any stage, with the entire job done on the spot.

Afterwards, there is paperwork for the insurer: a VAT invoice and a written report from the engineer.

## About High Friarside, briefly

High Friarside is a suburban area in County Durham, situated approximately 7 miles southwest of Newcastle upon Tyne. High Friarside sits at an elevation of 176 metres, surrounded by nearby places such as Lintz, Leazes, and Bryans Leap. High Friarside is characterised by its predominantly semi-detached housing stock, reflecting the typical residential development of the region. High Friarside is located inland, about 244 miles north of London.

## AdBlue drains across Durham, High Friarside included

AdBlue jobs in High Friarside are passed to teams that cover the towns near it — Lintz, Leazes as well as Bryans Leap — and much of Durham beyond, across NE postcodes.

Assuming won't help by a county line or somewhere tricky to pin down; ring and ask.

No towing is needed. In High Friarside, a residential suburb, a mobile service fits: your vehicle is emptied where it stands, whether on a drive, a side street, a car park or a forecourt.

## What AdBlue in a diesel tank costs to put right around High Friarside

Because each jobs differ, a single figure would not be honest.

What changes the price is, first, whether your engine has been running and for how long; then how much AdBlue was put in; and finally where the car is and whether a van can reach it safely, which is simpler on an open driveway than in a tight space behind Burnopfield Community Centre.

With that reason, every call from High Friarside opens by asking the same trio — what was put in, how much, if the engine ran — before a figure.

Once they are known, a range turns into one firm figure.

Priced on the call before the engineer heads out, it is paid for on the day — card or phone, no deposit.

While the van is travelling, dig out your policy: plenty include misfuelling.

## High Friarside: still beside the vehicle?

Right now, the best thing to do with the car is to not touch it.

Keys out; motor and ignition off.

Ring 0333 366 0103 and tell us it is AdBlue, about how much, and whether it's run. Petrol in Diesel takes it from there, in High Friarside or anywhere across Durham.
