# AdBlue in the Diesel Tank in West Laroch? Keep It Switched Off

Engine off, ignition off: that is where you start if AdBlue has got into the diesel tank.

Water with urea dissolved in it: that is AdBlue.

It does not burn, it does not mix with diesel, and the harm it does begins when your fuel system pulls it in.

If your engine has not run yet, AdBlue in a diesel tank is normally emptied and thoroughly rinsed where the vehicle sits in West Laroch.

Before you do anything else, call 0333 366 0103.

## Those opening minutes: AdBlue in your diesel tank around West Laroch

Do these:

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

- If you are at all close to moving traffic, put your hazards on.

- The empty bottle or the till receipt shows us the product and the amount, and so do not throw it out.

- Our van finds you fastest with a postcode starting PH49 4, or simply the name of a street nearby, and so phone from the car.

Things not to do:

- Not even briefly, and not to roll your vehicle: your motor remains off.

- Turning your key to ignition by itself sets the pump going on plenty of diesels. Skip it.

- Do not top up with diesel to thin it. AdBlue does not mix in diesel; it separates out.

- Never drive it anywhere, not even a short distance along MacColl Terrace.

- Draining the tank yourself by the road isn't worth trying.

The staff on duty at any West Laroch forecourt — the Gulf among them — will usually lend a hand rolling it aside if you ask.

Stopped on your own driveway? Then it remains just as it is.

## What AdBlue does in a diesel tank

AdBlue is made for your exhaust, not the motor.

Its own reservoir keeps it, and from there it's fed into your exhaust, where it treats the gas.

A fuel pump isn't designed to take it, and AdBlue was never supposed to go through one.

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

Denser than diesel, it drops and pools below it — the same place the intake sucks from.

Easiest of all: one that had AdBlue in Glencoe last night and has not been started since. The AdBlue sits at the foot of that tank, untouched — but it will be the first thing through if your engine runs, ahead of any diesel at all.

Two kinds of harm come from there.

What is left when the water goes is urea, which forms crystals: they settle in narrow passages and clog filters. On top of that, it eats at certain metals in the fuel system, and carries on till it's flushed out.

A car left sitting in West Laroch with AdBlue already in its lines is worse by the morning; one with AdBlue only in its tank is not.

The water in it causes damage of its own: the high-pressure fuel pump and the fuel injectors rely on diesel to lubricate them, and water gives them nothing.

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

Top up a diesel with petrol in error over at the Gleaner, and this problem is diluted fuel.

It mixes with your diesel, and whilst it is in your tank it does no damage; the damage comes from running the motor on it.

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

It cannot simply be run through, because it does not burn.

Nor can it be thinned, since it splits back out — and the next fill will not clear away crystals or corrosion. So the flush counts for more with AdBlue, and trying your engine "to see", in the heart of West Laroch or out in North Ballachulish, does more harm than nearly any other error.

The good news is the same as with petrol.

Wherever across Highland the car has stopped, an unstarted engine means the AdBlue yet in the tank: the simplest bit of any fuel system to empty.

## West Laroch: how AdBlue ends up in a diesel tank

Many cars put the AdBlue filler beside the diesel one, occasionally under one flap, and after dark the two may look identical. No one intends it.

It usually occurs outside the house, from a bottle grabbed en route home, not at the forecourt.

A couple of familiar ways cover most cases.

Hurrying, outside the local primary school, after a warning lamp came on during the school run, a parent tops up the car.

A driver tips the container in at home, right off West Laroch, as the day ends.

Else, in dim light outside The Laroch, your car gets refilled by someone using that flap for the first time.

It happens most in the vehicles drivers know least: a hire car, a new car, a company car, or the second motor of a household with one diesel and one petrol.

Anywhere around Highland, West Laroch as well, the mistake does not change, and neither does the first step: leave it off.

## West Laroch: started your engine with AdBlue in your diesel tank?

In that case, the AdBlue is no longer inside the tank.

Through your filter, along the lines, and — with any running — into the high-pressure pump and each injector: that's where it travels.

Lumpy running, smoke from the exhaust, dropping power, dashboard warnings or cutting out: any might appear, perhaps part way across West Laroch or coming back from Jubilee Park.

When safe, pull over then switch everything off — with no restarting to see.

Every start pulls more of it through.

West Laroch lies over 50 miles from the M8; if you were on it, exit by the next junction and pull up safely rather than driving on.

Each mile carries the AdBlue further into the system. That's why crossing West Laroch to park beside Cairn Memorial and a drive of over 50 miles towards Stirling are such separate jobs.

Tell us roughly how far it had come.

Once the motor has been run, the flush takes in more, and all of it is done where the vehicle has come to a stop.

Very rarely does it leave long-term damage when it's caught quickly.

## What does an AdBlue drain on a diesel involve around West Laroch?

A road by Well Being Shed, a drive, a lay-by or a forecourt: wherever the vehicle has stopped around West Laroch, our technicians come to it.

What got in, about how much, and if the motor has turned over: we check first, since those shape the work.

Then your tank is cleared where your car waits, and so the tainted fuel and the AdBlue come out together.

The system is cleaned thoroughly, which matters more with AdBlue than with petrol, because what it leaves behind does not rinse out on its own.

Fresh diesel goes in once the fuel filter is flushed — or swapped, if it needs to be — and then the car is tested.

Not run? In that case expect about half an hour on site for most jobs.

Our pumping gear is explosion-proof, and so a busy forecourt is no issue, and it is hushed enough for a residential street late at night.

Bleeding the fuel system with new diesel comes last.

Firing it up comes next, and then you drive off from where the vehicle is parked, by Fort William or on a driveway in West Laroch.

We make sure it runs correctly on clean diesel before we leave.

Our engineers do it all wherever the vehicle has ended up, and it never has to be taken to a workshop.

You receive a VAT invoice and an engineer report after that, which is what insurers want.

Our teams that answer AdBlue jobs in West Laroch also cover the spots round it, Brecklet, East Laroch and Ballachulish among them, and most of Highland beyond, across the PH postcode area.

Guessing won't help close to a county line or somewhere tricky to describe; phone and ask.

A van that comes to you fits West Laroch, a residential suburb: you have no need to take the car to us, since we empty it there, on a driveway, a side street, a car park or a filling station.

## West Laroch: what AdBlue in a diesel tank costs to fix

There is no honest single quote, because the jobs are not the same.

What shifts the cost is, first of all, whether the motor has run and for how long; then how much AdBlue went in; and finally where the vehicle is and whether our van can get to it safely, which is simpler on an open driveway than in a tight space behind Cnocan Dubh Hill Fort.

Which fluid was put in, what quantity, and whether it ran: every West Laroch call begins by asking exactly those, before a quote, not afterwards.

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

Before a van sets off, you are told the price by phone. And you pay on the day, card or over the phone, with nothing in advance.

While our engineer is on the way, check your policy: plenty include misfuelling.

## West Laroch: still next to the vehicle?

Then the most helpful thing you can do is nothing to the vehicle.

Keys out, engine off, ignition off.

Call 0333 366 0103: AdBlue, roughly how much, plus whether it ran are all we need. Petrol in Diesel takes over the rest throughout Highland, West Laroch included.
