# Summerhill: How Does AdBlue End Up in a Diesel Tank, and How Do You Prevent It?

AdBlue already in your diesel tank? In that case set this page aside for now, leave your ignition and motor off, and call 0333 366 0103.

Caught before your engine runs, it is normally a drain and a thorough flush, done where the car is in Summerhill.

If you are reading before it has happened, the remainder of this page is about why it takes place and how to make sure it does not.

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

Many newer diesels on the roads around Summerhill and Cornhill carry two liquids, not one. Diesel goes to your engine.

Kept in a tank of its own, AdBlue is sprayed into your exhaust gas to clean it.

Different tanks, separate fillers.

Other motors keep the AdBlue filler in the boot or under the bonnet; plenty more have the two side by side behind one flap.

Topping up your diesel side at the pump happens constantly.

The AdBlue side is fuelled far less commonly, usually from a bottle, and normally by somebody who has to stop and think where it goes.

The slip lives in that gap.

## Summerhill: how AdBlue in your diesel tank takes place

Carelessness seldom causes it. What does is three things coming up together.

On a driveway off Stronsay Drive before work, or in the car park outside Grays Inn on the way home: that's where the hurried top-up takes place. Why the rush? As AdBlue gets low the car warns you, and once it's gone, limp mode follows.

The old car's cap is where the hand reaches — but a rental car, a new car or a company car keeps the fillers elsewhere. That's a second thing: a strange motor.

Lastly, the spout goes in: diesel filler or AdBlue filler, it slides in just as easily, and once the pour begins, nothing stops it.

Whether it occurs in Mastrick or the middle of Summerhill, it is the same few seconds.

## How to tell the AdBlue filler from the diesel one

Before you tip anything, whether on a driveway in Stockethill or a forecourt in Summerhill, check these. They take a few seconds.

- Colour and lettering: an AdBlue cap is regularly blue, or says "AdBlue", where a diesel cap usually does not. Go by the cap, not where it sits.

- The size. On many vehicles the AdBlue filler neck is the smaller of the two.

- The flap. Look inside the fuel flap for a label. Many vehicles say there which fuel goes where.

- Can't see it beside the diesel inlet? Then look below the bonnet or in your boot — the handbook will say which.

- Whoever had it before will know. Check when you pick up a hire car or company car — at Aberdeen's car park, perhaps — not once the light comes on.

## Topping up AdBlue without it reaching the diesel tank

On the day the light appears — wherever you are in Aberdeen City — a simple routine to follow.

- Switch off once parked — level ground, engine stopped, and not in a rush beside Stronsay Place on the verge.

- Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds silly and it works.

- The two behind a single flap? Then confirm the cap on your diesel filler stays shut before raising the bottle.

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

- Before starting the vehicle, close the cap and check again that your diesel cap never came off.

If at stage two or three you find you have already poured into the diesel side, stop there.

Step five is off limits.

## AdBlue in your diesel tank already, in Summerhill?

Then the order of things is short. Do not start the motor.

Leave your ignition off too, since on many diesels switching it on by itself runs your fuel pump.

AdBlue does not mix with diesel — it sinks to the bottom of that tank, where your fuel is drawn from — so don't top up with diesel to thin it.

The attendants at Shell, Co-op or any forecourt will usually lend a hand to push your car clear when you ask.

If you are on your own driveway in Summerhill, leave the car where it stands.

Already run? Stop when it is safe, then turn off.

Leave the M90 — over 50 miles out of Summerhill — at the first junction.

A short hop across Summerhill is a smaller job than a run towards Aberdeen, under 3 miles away, and so tell us about how far it went.

## Summerhill: what takes place when our engineers get there

Anywhere the vehicle came to rest, whether outside the local primary school, beside Summerhill Parish Church or at home, the van comes to it.

Both the work and our price rest on three answers — what fluid, which quantity, and if it's run — so our engineers ask.

Nobody sets off until you've had the price by phone.

Then the tank is cleared and the fuel system flushed thoroughly.

More than with petrol, it counts with AdBlue: crystals build up, some metals are attacked, and nothing clears out on its own, however long it sits.

A test is last: before that, clean diesel is added, and your filter is cleaned or replaced if necessary.

We do not leave until it has been started and is running correctly.

If the motor has not run, most jobs take about half an hour once we're there, using pumps that are safe on a working forecourt and quiet enough to use outside a house after dark.

Payment is on the day, not upfront, and you receive the paperwork your insurer asks for: an engineer's report and a VAT invoice.

Misfuelling cover is included in many insurance policies — so use the wait to check yours.

## About Summerhill, for a moment

Summerhill is a suburban area located on the riverside in Aberdeen City, Scotland, with an elevation of 94 metres. Summerhill sits approximately 2.5 miles from Aberdeen city centre and is surrounded by nearby places such as Mastrick, Craigiebuckler, and Sheddocksley. Summerhill is predominantly composed of flat-type housing and is home to around 4620 residents. Summerhill is situated in a scenic area, with the River Don flowing nearby.

## AdBlue drains across Aberdeen City, Summerhill included

Summerhill is a residential suburb, and our vans that cover it also work the places around it, Craigiebuckler and Sheddocksley among them, across the AB postcode area.

Fastest of all: give a AB15 6 postcode to our van.

No need to shift the vehicle.

Our technicians drain it where it is — a side street near Sheddocksley Baptist Church, a lay-by on the way to Stronsay Park, a driveway.

If you are near a border, or somewhere hard to describe like the back of Aberdeen Indoor Bowling Club, ring and ask instead of guessing.

## Summerhill people: the short version

Pour no AdBlue until you've read the cap.
