# West Hanney: AdBlue in the Diesel Tank? Leave It Off

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

AdBlue is urea mixed in water.

Unlike fuel, it neither burns nor blends, and no harm starts till the motor sucks it round.

If your motor hasn't run yet, AdBlue in a diesel tank is usually drained and carefully flushed where the vehicle sits in West Hanney.

Phone 0333 366 0103 before you do anything else.

## Your next steps straight away, West Hanney: AdBlue in the diesel tank

Things to do:

- Keys out — that way nobody can power anything on.

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

- Hold on to the receipt or the empty bottle, so you can tell us what got in and about how much.

- Call us from where you are. A postcode starting OX12 0, or the name of the nearest street, gets the van to you without a search.

Don't:

- Moving the car even a short way is no reason to fire up the motor.

- Don't switch your ignition on. On many diesels that alone runs the fuel pump.

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

- Don't drive it anywhere, not even a short distance up North Green.

- No draining it yourself, at all, at the verge.

Ask the people behind the counter to help you roll the vehicle away from the island if you're at a forecourt around West Hanney, whether it's the JET or somewhere else.

On your own drive, do not touch it at all.

## AdBlue in a diesel tank, and what it does there

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

From a separate tank it is fed directly to the exhaust, cleaning what your engine lets out.

No part inside a fuel pump is made for this liquid — and none of that was intended to go that way.

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

It sinks, because it's denser than diesel, and pools low where the pickup draws its fuel from.

A vehicle filled on a drive in Grove yesterday evening and not started since counts as the straightforward case. No pump has sucked the AdBlue up yet — but when the engine turns, that is what goes first, directly from the bottom of that tank.

Two kinds of harm come from there.

It eats at some metals used in fuel systems, working on any part it reaches till it's cleared completely. And when the water evaporates, the urea forms crystals that block filters and lodge in tiny channels.

Where the AdBlue has reached the lines, waiting overnight in West Hanney leaves it worse. Inside your tank only, waiting costs nothing.

And there's the water: it offers no lubrication to the parts that need it the most — the high-pressure pump and each injector.

## Petrol or AdBlue in a diesel: why AdBlue is often worse

Petrol put into a diesel on another forecourt nearby's forecourt leaves your fuel thin — that's the main issue.

No harm is done as long as it stays put, blended into your diesel — only once your motor runs on it.

AdBlue in a diesel is another matter: not thin fuel, yet no fuel at all.

It can't simply be run through, because it doesn't burn.

Deposits and corrosion remain through the next tankful, and AdBlue separates again from the diesel, and so watering it can't work. That is why the flush counts so much, and trying your engine "to see" costs more with AdBlue than almost any other slip — in Charney Bassett or the heart of West Hanney alike.

The good news is the same as with petrol.

Emptying a tank is the easiest job on a fuel system, and with no running, the AdBlue stays in it — anywhere across Oxfordshire your car has stopped.

## AdBlue in a diesel tank around West Hanney: how it ends up there

After dark, two caps side by side — the AdBlue one and the diesel cap, now and then behind a single flap — may appear the same. Nobody means it; plenty of designs allow it.

Usually it's not the forecourt: someone buys a bottle driving home and tips it in outside the house.

Usually, it happens in one of a few familiar ways.

A warning light comes on during the school run, and the top-up takes place in a hurry outside St James Church of England Primary School, Hanney.

A bottle is poured in at the end of the day on a drive just off School Road.

One more version: dim light, a pub car park outside The Plough, and a driver using that flap the first time.

Hired motors, new motors, company vehicles, or the spare car in a home with one of each: the least known cars get it most.

Wherever around Oxfordshire, West Hanney as well, the mistake doesn't change, and neither does the first response: keep it off.

## AdBlue in the diesel tank around West Hanney, and your engine started?

Then the tank is no longer where the AdBlue is.

Given any running time, it travels to the high-pressure pump and every injector, having passed through the fuel filter and pipework.

You may see your motor running unevenly, smoking, losing power, showing warning lights or cutting out, maybe on the way back from Nigel Eady Community Woodland or halfway across West Hanney.

When you safely can, pull over then switch everything off — without restarting to test.

With each start, more of it is pulled through.

If you were on the M4, under 15 miles from West Hanney, come off at the next junction and stop somewhere safe instead of pressing on.

Distance counts: each mile carries the AdBlue further in, and so heading for Oxford, under 15 miles away, gives a far bigger job than hopping across West Hanney to the car park by Saint James the Great.

Let us know about how far it had come.

There's more to rinse out once the motor has run, and we do all of it where the car has come to a stop.

When it is spotted soon, lasting damage is very uncommon.

## Emptying AdBlue in a diesel in West Hanney: what it takes

The vehicle remains where it is, whether that's a street near Hanney War Memorial Hall, a driveway, a layby or a forecourt in West Hanney, and our van comes to it.

The work rests on three replies, and our technicians ask for first — what got in, the amount, and whether the engine has run.

Next, emptying your tank on the spot removes the contaminated diesel along with the AdBlue together.

Residue from AdBlue won't wash out unaided, and so the whole system gets a careful flush, which matters far more with urea than with petrol.

Fresh diesel goes in once the filter is cleaned — or replaced, when it needs to be — and then your car is tested.

Engine not run? Then count on about half an hour once we are there for most jobs.

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

The final step is to prime your system on new diesel.

Whether it's a parking bay at Appleford or a drive around West Hanney, that is where our engineers start it and you drive off.

Our technicians check it runs correctly on fresh diesel before we go.

The whole job is done where your car is, so it never has to go to a workshop.

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

## West Hanney and Oxfordshire: AdBlue drains across the area

AdBlue jobs around West Hanney go to vans that cover the places around it — East Hanney, Lyford plus Denchworth — and most of Oxfordshire further out, throughout OX postcodes.

Close to a boundary, or anywhere tricky to explain? Asking is better than assuming, so ring.

No towing is needed. In West Hanney, a village, a mobile service works: the vehicle is emptied where it stands, be it on a driveway, a side street, a car park or a filling station.

## What AdBlue in a diesel tank costs to put right around West Hanney

Since each jobs vary, a single figure would not be fair.

Three things shift the cost: whether the engine has run and for how long, how much AdBlue was put in, and where the vehicle is. That last one rests on whether our van can reach it safely, and an open driveway is simpler than a tight gap behind Site of Wantage Road Station.

That's why each call from West Hanney starts with the same three queries, asked before giving a figure, not after: what was put in, how much, and if it's run.

Those replies turn a range into a straight price.

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

While the van is travelling, check your policy: many cover misfuelling.

## West Hanney: still alongside the car?

Then, do nothing — that is the most helpful move available.

Motor off, keys out, ignition off.

Ring 0333 366 0103: AdBlue, the amount, and if it ran are everything our engineers need. Petrol in Diesel takes over the remainder across Oxfordshire, West Hanney too.
