# AdBlue in a Diesel Tank in Old Balornock: How It Happens and How to Avoid It

AdBlue already in your diesel tank? Then put this page down a moment, keep your ignition and motor off, and phone 0333 366 0103.

Usually, when your motor has not run, it's drained and fully flushed where your car sits around Old Balornock.

The rest of this page covers why it occurs and how to ensure it does not — handy if you are reading ahead of time.

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

Plenty of modern diesels around Barmulloch, like those in Old Balornock, run on two liquids; the motor takes just your diesel.

AdBlue goes to your exhaust, where it is sprayed into the gas to fresh it, and it lives in a tank of its own.

Separate tanks, different fillers.

Under one flap, side by side: that is the arrangement on many motors. Elsewhere, AdBlue's filler sits under the bonnet or in your boot instead.

Diesel gets filled on each filling station visit, week in, week out.

Someone who has to stop and work out where it goes usually tops up the AdBlue side, from a bottle, and far less regularly.

Mistakes happen in that gap between the two.

## How AdBlue in the diesel tank occurs around Old Balornock

Rarely is it carelessness: usually three things coincide.

On a driveway off Broomfield Road before work, or in the car park outside New Morven Bar heading home: that's where the rushed top-up happens. What is the reason for the rush? As AdBlue runs low the car warns you, and if it is gone, limp mode follows.

Then, your hand reaches for the cap it knew on the old motor — since a rental car, a new motor or a company car puts the fillers where your last one didn't.

And the bottle fits. A bottle with a spout goes into a diesel filler as easily as an AdBlue one, and so nothing stops the pour once it has started.

The same few seconds decide it, in the middle of Old Balornock or out in Springburn.

## Telling the AdBlue filler from the diesel filler

Before you tip anything, whether on a drive in Auchinairn or a forecourt around Old Balornock, check these. They take a few seconds.

- Position can mislead; the cap does not. AdBlue ones tend to be blue or bear the name "AdBlue" — diesel ones usually do not.

- Look at the size: the smaller neck is, on plenty of motors, the AdBlue one.

- Open the flap and check for a label — many motors show what goes in each filler right there.

- The handbook says where it is if your filler isn't next to your diesel cap: the boot, or under the bonnet.

- Whoever had it before will know. Ask as you pick up a hire car or company car — at Springburn's car park, say — not once the warning comes on.

## How to top up without AdBlue in the diesel tank

Anywhere around Glasgow City the light comes on, here is a routine for that day.

- Park and switch off. Not on a slope, not with your engine running, and not in a rush on the side of Campsie Street.

- Find the AdBlue filler, read the cap, and say the word "AdBlue" out loud as unscrewing it. It seems silly. It does the trick.

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

- Using the bottle's own spout, pour slowly — and stop when it's full or the bottle is empty.

- Close the cap, then check again — making sure the diesel filler stayed closed throughout. After that, start the car.

Spot at stage two or three that it's already gone into your diesel side? Then stop just there.

Never go on to stage five.

## Old Balornock: already put AdBlue in the diesel tank?

What follows is a short order of things, beginning with not starting the engine.

The fuel pump runs on many diesels the moment your ignition is switched on — and so leave it off.

Don't top up with diesel to dilute it: AdBlue doesn't mix with diesel, it sinks to the bottom of your tank, where the fuel is pulled from.

The attendants at JET, Shell or another forecourt will usually help pushing the car away if you ask.

At home around Old Balornock? Then your car remains put.

When your engine has run already, pull over somewhere safe and switch the car off.

Old Balornock lies under a mile from the M80; there, take the first exit.

Tell us roughly how far it went: a run towards Glasgow, under 3 miles away, is a bigger job than a short hop across Old Balornock.

## What happens when our technicians get there in Old Balornock

Outside the local primary school, close to Brunswick Youth Centre or on your own drive: wherever your car has stopped, we come to it.

Both the work and the quote rest on three answers — what liquid, what quantity, and if it has run — so our technicians ask.

During the call itself, you hear the price — ahead of anything else.

The fuel system is then rinsed thoroughly, once your tank is emptied.

AdBlue crystallises and is corrosive to some of the metals in a fuel system, so it does not wash out on its own — which is why the flush counts more with AdBlue than with petrol.

A test is last: before that, clean diesel goes in, and the filter is flushed or changed if necessary.

Next our technicians start it and check it runs properly before we leave.

Unstarted vehicles mostly mean a half-hour job from the moment we arrive. The equipment is safe on a busy forecourt, and hushed enough for a driveway late at night.

The insurer will ask for the engineer's report and the VAT invoice, and both are yours once this job is done. Payment is on the day, with no deposit.

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