# AdBlue in a Diesel Tank in Gisburn? Don't Start It

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

Urea mixed in water is what AdBlue is.

Unlike fuel, it neither ignites nor blends, and nothing happens till the motor sucks it round.

Caught before your motor has been run, AdBlue in a diesel tank is usually a drain and a thorough flush, done where the vehicle is in Gisburn.

Nothing comes before ringing 0333 366 0103.

## Gisburn, AdBlue in the diesel tank: what to do right away

Do these:

- So no one can turn the ignition on, pull the keys away.

- Put the hazards on if you're at all near moving traffic.

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

- Tell us a postcode starting BB7 4, or whatever street lies nearest, and the van reaches you straight — so call wherever you stand.

Not to do:

- Not even for a second, and not to shift the vehicle: the motor remains off.

- Plenty of diesels power their pump the moment your ignition comes on, so keep the vehicle off.

- No more fuel on top. The AdBlue won't mix, so it's pointless.

- Keep it where it is rather than driving it anywhere, even a short stretch along Mill Lane.

- Don't try to drain the vehicle yourself by the roadside.

Moving the vehicle away from the pumps is a job for staff to help with, whichever Gisburn forecourt you are on, the Texaco included.

At your own drive, do not touch it at all.

## What AdBlue does in a diesel tank

Made for your exhaust, AdBlue has no place in the engine.

From a separate tank it goes directly to your exhaust, cleaning what your motor lets out.

Nothing inside an injection pump is made for this liquid — and no part of that was intended to travel through one.

Fuel mixes; AdBlue, once tipped in, will not. Its behaviour is nothing like diesel's.

The intake sucks fuel from the deepest part of your tank, and that's just where AdBlue ends up: being denser than diesel, it sinks.

Simplest of all: a vehicle that had AdBlue in Paythorne last night and has not turned since. The AdBlue sits at the foot of the tank, undrawn — though it will be the first thing through if the motor runs, before any diesel at all.

It causes two kinds of damage from there.

As its water goes, the urea left behind crystallises, and the crystals block filters and settle in fine passages. And it is corrosive to some of the metals a fuel system is made from, and so it keeps working on the components it hits for as long as it stays there.

Overnight, a vehicle sitting in Gisburn with AdBlue through its pipework grows worse; where it's only inside that tank, it doesn't.

Water lubricates nothing. The high-pressure pump and every injector need diesel flowing through them, so the water part damages them in its own right.

## AdBlue in a diesel: why it is often worse than petrol

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

No damage is done as long as it sits put, blended into your diesel — only once your motor works on it.

The issue with AdBlue in a diesel is a completely unsuitable liquid.

Since it doesn't burn, running it through isn't an option.

It doesn't stay mixed, so it cannot be diluted. And crystals and corrosion do not wash out with the next tank of fuel. That is why the flush matters more with AdBlue than with petrol, and why starting the engine "to see" costs more here than almost anywhere else, whether your car is in Newby or the middle of Gisburn.

The same good news applies as with petrol.

Not run? Then the AdBlue waits only in the tank, the simplest section of the whole system to empty, anywhere your vehicle has stopped around Lancashire.

## How AdBlue ends up in a diesel tank in Gisburn

Many cars put the AdBlue filler alongside the diesel one, occasionally under a single flap, and after dark the two can look identical. Nobody intends it.

Mostly it is never the filling station: a driver picks up a container driving home and tips it in outside the house.

Mostly, it occurs in one of a few familiar ways.

Hurrying, outside Gisburn Primary School, after a warning lamp came on during the school run, someone refills the vehicle.

A bottle is poured in at the end of the day on a drive just off A59.

Or a driver new to that flap refills your vehicle in dim light, stopped in the car park by The White Bull.

The least familiar vehicles see it most — rentals, new cars, fleet cars, and the other vehicle in a family with one of each fuel types.

An identical mistake, an identical first response — leave it off — anywhere you are around Gisburn or the rest of Lancashire.

## Gisburn: started the motor with AdBlue in the diesel tank?

The AdBlue has left your tank, then.

With any running, it goes on to the injection pump and each injector, after passing via the filter and pipework.

Perhaps coming back from Ten Acre Plantation, or part way across Gisburn, your engine might run rough, smoke, lose pace, flash the dash or cut out.

Once safe, pull over then switch everything off — with no turning it on again to see.

With each start, more of it is pulled through.

Gisburn sits under 10 miles from the M65; if you were on it, exit by the next junction and pull up safely rather than carrying on.

Every mile carries the AdBlue deeper into the system. That's why a hop across Gisburn to park beside Gisburn Festival Hall and a drive of under 25 miles for Preston are very distinct jobs.

Roughly how far it had come is worth telling us.

Wherever the car came to a halt is where all of it gets done, even with more to rinse out once the engine has been running.

Permanent damage is very rare when it's spotted quickly.

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

A street beside St Mary the Virgin, a drive, a lay-by or a filling station: wherever the car has come to rest around Gisburn, we come to it.

The work rests on three answers, which our technicians get before all else — which fluid got in, the amount, and whether your engine has run.

Next, draining your tank right there removes the polluted diesel along with the AdBlue in one go.

A careful flush counts far more after AdBlue than after petrol, since what remains will not clear out by itself.

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

Roughly half an hour on site is typical for most jobs when the motor has not run.

Explosion-proof pumps make a busy forecourt sensible to work on, and they run quiet enough not to disturb the neighbours at night.

The final step is to bleed the system on new diesel.

Whether it's a parking space by Hellifield or a driveway around Gisburn, that is where we start the engine and you head off.

The test before we leave is that it runs smoothly on clean diesel.

We do it all wherever your car has stopped, and it never has to be taken to a workshop.

Afterwards, there is paperwork for your insurer: a VAT invoice plus a report from the engineer.

Gisburn lies near several other rural settlements, including Gisburn Cotes, Howgill, and Newsholme, and is approximately 21 miles from the city of Preston. Gisburn has a population of around 567 people, predominantly living in terraced housing. Gisburn is located in the North West of England, about 190 miles from London.

## AdBlue drains across Gisburn and Lancashire

Over the BB postcode area, the teams answering AdBlue jobs in Gisburn reach most of Lancashire too, Gisburn Cotes, Howgill and Newsholme among them.

Assuming doesn't help close to a border or anywhere tricky to describe; phone and check.

Gisburn is a village, and an on-site drain suits it: whether the car is on a home drive, a residential street, a car park or a forecourt, our technicians drain it where it is, and so it never needs to be moved to us.

## Gisburn: what AdBlue in a diesel tank costs to fix

There's no fair single price, since the jobs aren't the same.

Three things shift the cost: whether the engine has been running and for how long, how much AdBlue got in, and where the vehicle is. That last one rests on whether our van can reach it safely, and an open driveway is simpler than a tight gap behind Gisburne Park.

Ahead of a quote, not after, every call from Gisburn opens with the same three checks: the fuel, the amount, and if the engine ran.

Those replies turn a range into a straight quote.

Our price is quoted on the call, before anyone leaves; payment happens on the day, by card or over the phone, and nothing upfront.

Check your policy while we're on the way: plenty carry misfuelling cover.

## Still next to the car in Gisburn?

Then, the most helpful thing to do with the vehicle is to leave it.

Keys out, motor off, ignition off.

Petrol in Diesel takes over the rest, in Gisburn or anywhere in Lancashire, after you call 0333 366 0103 saying it's AdBlue, roughly what quantity, and if the engine ran.
