# AdBlue in the Diesel Tank in Neat Enstone? Keep It Switched Off

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

Water with urea dissolved in it: that's AdBlue.

Unlike fuel, it neither burns nor blends, and nothing starts until your motor sucks it round.

A drain and a thorough flush, done where the car is around Neat Enstone, is usually all AdBlue in a diesel tank needs — if it's caught before the motor has been run.

Phone 0333 366 0103 before you do anything else.

## What to do straight away, Neat Enstone: AdBlue in the diesel tank

Things to do:

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

- Put the hazards on if you're anywhere close to moving traffic.

- Which product, and roughly how much volume? Save the bottle or the receipt, and our engineers can know.

- Our van finds you quickest with a postcode starting OX7 4, or just the name of a street nearby, and so phone from the spot.

Not to do:

- No starting the motor — not for a second, not to shift your car.

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

- AdBlue does not mix in diesel — it separates out — so adding more fuel won't thin it.

- Keep it where it is rather than driving it anywhere, even a short stretch down Cleveley Road.

- Beside the road, do not attempt draining it on your own.

On a forecourt around Neat Enstone, whether it's the Texaco or another one, ask the staff to help you push your car clear of the petrol pump.

If you're on your own drive, leave the car exactly where it sits.

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

Not your engine but the exhaust is where AdBlue belongs.

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

No part in an injection pump is made for this fluid — and no part of it was meant to go through one.

Tipped in with your diesel, it keeps apart rather than mixing — entirely different from fuel.

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

When your system runs, the AdBlue is top of the list to be pulled through. Until then it sits underneath your diesel, and that is why a vehicle topped up in Cleveley yesterday and not switched on stays the simple one, provided nobody turns the key.

It causes two kinds of damage from there.

Crystals and corrosion. As the water dries, it strands urea that hardens in filter elements and tiny channels; and, since it eats at certain metals, every part it reaches keeps suffering for as long as it stays in there.

If the AdBlue is in the pipework, leaving it till morning around Neat Enstone leaves things worse. In your tank only, waiting costs nothing.

Diesel protects the injection pump and each injector as it flows; water gives none of that, which is a second form of harm.

## Why AdBlue in a diesel is often more significant than petrol

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

Damage only comes from running on it. Blended into your diesel and sitting in your tank, it causes nothing.

With AdBlue in a diesel, the liquid itself is plainly the wrong one.

Not burning, it cannot simply be run through.

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

The good news is the same as with petrol.

Wherever around Oxfordshire your vehicle has stopped, an unrun engine means the AdBlue still inside the tank: the easiest bit of any fuel system to empty.

## How does AdBlue end up in a diesel tank in Neat Enstone?

Many cars put the AdBlue cap beside the diesel cap, now and then behind a single flap, and in dim light the two can look the same. Nobody means it.

A bottle bought when heading home and tipped in outside the house, rather than at the filling station, is the usual story.

A couple of familiar ways cover most cases.

Midway through the drop-off, the dashboard warns, and outside Enstone Primary School the top-up is hurried.

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

One more version: darkness, a pub car park outside The Harrow Inn, and a driver using that flap for the first time.

It comes up most in a hire car, a brand-new vehicle, a fleet motor, or the spare car of a family with both fuel types — the cars drivers use least.

An identical slip, an identical first step — keep it switched off — anywhere you are around Neat Enstone or the remainder of Oxfordshire.

## Started the motor with AdBlue in the diesel tank in Neat Enstone?

Then your tank is no longer where the AdBlue is.

Your filter and lines have had it sucked along, and some running time takes it on to the high-pressure pump and each injector.

Rough running, smoke, dropping power, dashboard lights or stalling: any may appear, maybe part way across Neat Enstone or returning from Enstone Playing Field.

No starting it again to test: stop when safe, then switch everything off.

Every start pulls more of that through.

Neat Enstone lies under 10 miles from the M40; if you were on it, leave at the first junction and pull up safely instead of carrying on.

How far it went counts. A few hundred yards across Neat Enstone to the car park by Saint Kenelm is a very different job from a run towards Oxford, under 15 miles away, with the AdBlue reaching further into the system with every mile.

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 rinse out after the motor has been running.

Noticed quickly, it very seldom leaves long-term damage.

## What clearing AdBlue from a diesel involves in Neat Enstone

Our engineers come to your car, wherever it has stopped in Neat Enstone: a side street close to Bath House, a drive, a lay-by or a forecourt.

The work rests on three replies, which our technicians get before all else — what was put in, the quantity, and whether your engine has turned over.

Next, emptying your tank on the spot takes out the polluted diesel along with the AdBlue together.

With AdBlue, more so than with petrol, the flush matters: the whole system is flushed all the way through because residue will not wash out unaided.

The filter is cleaned, or replaced where it needs to be; clean diesel goes in; and the car is tested.

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

The pumps are explosion-proof, fine on a busy forecourt and quiet enough to use outside a house at night.

New diesel goes in to prime the system, and that is the final step.

After that we fire it up and you set off, whether from a parking bay outside Charlbury or a drive in Neat Enstone.

The test before our technicians go is that it runs properly on fresh diesel.

Our engineers do it all wherever the vehicle has stopped, and it never needs to go to a workshop.

Insurers ask for a VAT invoice and an engineer report, and both come at the end.

A van that comes to you suits Neat Enstone, a residential suburb: there's no need to take the car to us, since we drain it there, on a drive, a residential street, a parking area or a filling station.

## Neat Enstone: what AdBlue in a diesel tank costs to fix

There is no fair single quote, since the jobs aren't the same.

The cost shifts first with how long, if at all, the engine has been running, and next with the quantity of AdBlue that went in. After that it turns on where the vehicle is and whether a technician can reach it safely, which is easier on an open drive than in a tight space behind Nether Chalford.

Which fluid went in, how much, and if the engine ran: every Neat Enstone call begins by asking precisely that, before any quote, not after.

When those are answered, a range turns into one fixed number.

Our price is quoted during the call, before a van leaves; payment comes on the day, by card or by phone, and nothing upfront.

Many insurance policies include misfuelling cover, so it is worth checking yours whilst we are on the way.

## Neat Enstone: still next to the vehicle?

Then, touch nothing — that is the best move there is.

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 Neat Enstone or anywhere in Oxfordshire.
