# Why It Happens and How to Prevent It: AdBlue in a Diesel Tank in Barleythorpe

AdBlue already in your diesel tank? In that case put this page aside for now, leave the ignition and engine off, then phone 0333 366 0103.

Normally, when the engine hasn't turned, it is emptied and fully rinsed where the vehicle sits around Barleythorpe.

Nothing happened yet? Below, the page covers the why it happens and the ways to prevent it for good.

## Two fillers, two tanks: AdBlue in a diesel vehicle

Diesel feeds your motor — but plenty of newer diesels driven round Barleythorpe and Burley carry a second fluid as well.

Stored in a tank of its own, AdBlue is sprayed into your exhaust stream and cleans it.

Every tank has one filler of its own.

Other motors put the AdBlue filler in your boot or under the bonnet; a lot of others have the two together under one flap.

Diesel gets filled at every filling station visit, again and again.

Far less commonly, the AdBlue side gets filled — normally from a bottle, by someone thinking about where it goes.

That gap is where the slip lives.

## How does AdBlue in your diesel tank occur around Barleythorpe?

Seldom is it carelessness: normally three things line up.

Haste comes from the warning. The vehicle tells you as AdBlue runs low, and an empty tank sends the vehicle into limp mode — so the top-up gets done in a rush, before work on a drive off Manor Lane, or on the way home in the car park at The Old Buttercross.

The old car's filler is where your hand goes — yet a hire car, a new car or a company car keeps the fillers somewhere else. That is a second factor: a strange car.

Nothing stops the pour after it has started, because a bottle with a spout goes into a diesel filler as easily as an AdBlue one. The bottle fits.

Whether it takes place in Oakham or the middle of Barleythorpe, it is the same few seconds.

## Telling the AdBlue filler from the diesel filler

Look at these before pouring, on a forecourt around Barleythorpe or a driveway over in Egleton. Seconds, no more.

- Check the cap instead of going by position: AdBlue ones are often blue or marked "AdBlue", and diesel caps usually aren't.

- Look at the size: the smaller filler neck is, on many vehicles, the AdBlue one.

- Check inside the fuel flap: plenty of vehicles have a label there showing which fuel goes where.

- In your boot or under the bonnet: that is where the filler is if it is not by the diesel cap, and the handbook says which.

- The person who drove the car last. On a hire or company car picked up from somewhere like the car park at Oakham, ask before you leave, not when the light comes on.

## Keeping AdBlue out of the diesel tank when you top up

Wherever in Rutland the light comes on, this is a routine for that day.

- Pull in somewhere level, motor off, with time in hand — never rushing on the side of Main Road.

- Silly as it sounds, speaking "AdBlue" out loud while you unscrew the cap works — after you have found your filler and read the cap.

- Leave your diesel cap on. If both sit under one flap, check the diesel cap is still closed before you lift the bottle.

- Gently is best, through the bottle's own spout, till it is full or the bottle is empty.

- Shut the cap, then look once more — confirm the diesel cap remained shut throughout. After that, start the car.

Stop there if you find, at step two or three, that you have already poured into your diesel side.

Skip step five entirely.

## Put AdBlue in your diesel tank in Barleythorpe already?

Then the order of things is short. Do not start your engine.

On many diesels the ignition alone runs the fuel pump, and so don't switch the vehicle on.

Thinning it with more diesel fails, because AdBlue settles to the base rather than mixing — and that's where the fuel is drawn from.

On a forecourt — BP, Essar or any other — the attendants will usually help roll the vehicle clear, if you ask.

Your own drive in Barleythorpe is the place it stays.

If your motor has already run, stop as soon as it is safe then switch off.

The next exit is the place to come off when you're on the M1, under 25 miles from Barleythorpe.

Roughly how far did it go? Crossing Barleythorpe is smaller work than a run of under 25 miles towards Leicester, so say.

## What happens when our technicians turn up around Barleythorpe

Our van reaches your car wherever it has come to rest — your own driveway, near Oakham Village Sign, or outside Langham CofE (Controlled) Primary School.

Both the work and our quote depend on three replies — what fluid, which amount, and if it has run — so our engineers ask.

On the phone call itself, you hear our price — before dispatch.

Then your tank is cleared and your system flushed thoroughly.

Not like petrol, AdBlue forms crystals and eats at some fuel-system metals, and neither clears out unaided. That is why it matters more.

Your filter is flushed, or replaced where it needs to be; fresh diesel goes in; and the car is tested.

Next our engineers start it and confirm it runs correctly before we go.

If the engine has not run, most jobs take about half an hour once we are there, using pumps that are safe on a busy forecourt and quiet enough to use outside a house at night.

The insurer usually wants the engineer's report and your VAT invoice, and both are yours once the job is done. Payment is on the day, with no money upfront.

Many insurance policies include misfuelling cover, and so it's worth checking yours whilst we're on the way.

Ring and ask rather than assuming if you're near a boundary, or somewhere hard to explain, like the back of Oakham Methodist Church.
