AdBlue in a Diesel Tank in Netherton? Don't Start It

AdBlue in the diesel tank? Then leave the motor off — and your ignition too. Chemically, AdBlue is just urea in water. As it is water-based, it won't ignite and never combines with diesel; damage only starts when your pump begins pulling it. A drain and a thorough flush, done where the vehicle is in Netherton, is generally all AdBlue in a diesel tank takes — if it is caught before your engine has run. Call 0333 366 0103 before you do anything else.

Those opening minutes: AdBlue in your diesel tank around Netherton

Things to do:

  • Pull the keys out, and so no one switches your ignition on.
  • Near moving traffic? So put the hazard lights on.
  • Which product, and about how much volume? Hang on to the bottle or your receipt, and we can see.
  • Ring us from where you are. A postcode starting WA6 6, or the name of the nearest street, brings our van to you without a search.

Never do these:

  • No starting the engine — not briefly, not to shift the vehicle.
  • Switching the key to ignition by itself starts your pump going on plenty of diesels. Avoid it.
  • AdBlue doesn't dilute in diesel — it separates out — so adding extra diesel will not thin it.
  • Keep the vehicle where it is instead of driving it anywhere, even a short way down Carriage Drive.
  • Do not try to drain the car yourself by the kerbside.

The staff on duty at any Netherton filling station — the Texaco included — will usually help rolling it clear if you ask. On your own driveway, don't touch it at all.

What AdBlue does in a diesel tank

Not your motor but your exhaust is where AdBlue is meant to go. It goes into its own tank and is sprayed into the exhaust gas to clean it. Neither side suits the other: urea doesn't belong in a pump, and a pump cannot deal with urea.

Fuel blends; AdBlue, once tipped in, will not. The behaviour is nothing like fuel's. The intake sucks fuel from the lowest part of that tank, and that's exactly where AdBlue ends up: as it is heavier than diesel, it sinks. The first thing your fuel system pulls through, once it runs, is the AdBlue. So a car that had AdBlue poured in on a drive in Newtown last night, and has not been started since, is still the straightforward case: the AdBlue is lying at the bottom of the tank, and nothing has drawn it in.

Two kinds of harm follow from there. What remains once the water evaporates is urea, which turns into crystals: they lodge in narrow channels and block filters. Worse, it eats at some metals in a fuel system, and keeps going until it is cleared out. By daybreak, a car sitting in Netherton with AdBlue in its lines grows worse; where it is just in the tank, nothing changes. And there's the water: it brings no protection to the parts that need it the most — the high-pressure pump and each injector.

Draining AdBlue from a diesel tank in Netherton

Why is AdBlue in a diesel often the bigger issue?

A fault of thinned fuel is what you get after fuelling a diesel with petrol at the Wharton Lake Garage. It mixes with your diesel, and while it is inside the tank it causes no damage; the damage comes from running the motor on it.

The trouble with AdBlue in a diesel is a totally unsuitable substance. It doesn't burn, and so it cannot just be run through. It doesn't stay mixed, so it can't be thinned. And crystals and corrosion don't wash out with the next tank of fuel. That is why the flush counts more with AdBlue than with petrol, and why starting the motor "to see" costs more here than nearly anywhere else, whether your car is in Fivecrosses or the middle of Netherton.

As with petrol, there is good news. Wherever across Cheshire your vehicle has stopped, an unstarted motor leaves the AdBlue yet inside the reservoir: the simplest part of a fuel system to empty.

AdBlue in a diesel tank in Netherton: how it ends up there

In dim light, two caps together — the AdBlue one and the diesel one, occasionally under a single flap — may look the same. No one means it; plenty of designs invite it. Usually it's never the forecourt: a driver buys a bottle heading home and tips it in at home.

It tends to take place in a few familiar ways. A warning light comes on during the school run, and the top-up occurs in a hurry outside Frodsham CofE Primary School. In the evening, a container goes in on a driveway close to Howey Lane. Or a driver unfamiliar with that flap refills the car in dim light, parked in the car park outside Netherton Hall.

It happens most in the motors motorists 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 across Cheshire, Netherton included, the slip doesn't change, and nor does the first step: leave it off.

Started the engine with AdBlue in your diesel tank in Netherton?

In that case, the AdBlue is no longer inside your tank. The filter and pipework have had it pulled along, and some running carries it on to the high-pressure pump and each injector.

Lumpy running, smoke, lost power, dashboard warnings or stalling: each may show up, perhaps part way across Netherton or coming back from Frodsham Hill Wood. No starting it again to test: pull over once it is safe, then switch it off. Each start pulls more of it through.

If you were on the M56, under a mile from Netherton, come off at the next junction and stop somewhere safe rather than pressing on.

Each mile pushes the AdBlue deeper into the system. That's why crossing Netherton to park beside Mersey View and a drive of under 10 miles for Chester are such different jobs. Let us know about how far it had come.

Once the engine has run, the flush takes in more, and all of it is done where the vehicle has come to a stop. Permanent damage is very unusual if it's noticed quickly.

What clearing AdBlue from a diesel involves in Netherton

Our engineers come to your car, wherever it has stopped in Netherton: a side street close to Frodsham War Memorial, a drive, a lay-by or a forecourt. The work rests on three answers, and our technicians get first — which fluid got in, the amount, and whether the motor has run.

Next, draining that tank right there removes the polluted diesel along with the AdBlue together. Residue from AdBlue will not wash away unaided, and so the fuel system gets a full flush, which matters far more here than with petrol. Your filter is flushed, or replaced where it needs to be; clean diesel goes in; and your car is tested. About half an hour on site is typical for most jobs where the engine has not run. The pumping gear is explosion-proof, so a live forecourt is no issue, and it is hushed enough for a residential street after dark.

Clean diesel goes in to prime the system, and that is the final step. You set off as soon as we have started it, and it makes no difference whether your car is on a drive in Netherton or in a space at Frodsham. Before we go, our technicians check it is running smoothly with new diesel in. No garage is required at any stage, with the entire job done on the spot. You get a VAT invoice and an engineer report later, which is what insurers want.

About Netherton, for a moment

Netherton is a small suburban area in coastal Cheshire, situated near the city of Chester and overlooking the Dee Estuary. Netherton has a relatively low elevation of 34 metres and is surrounded by other nearby places such as Marsh Green and Frodsham. Netherton is characterised by its predominantly detached housing stock, reflecting its suburban nature.

AdBlue drains around Netherton and across Cheshire

Marsh Green, Frodsham and Overton are among the places near Netherton that the same teams reach, together with most of Cheshire beyond, throughout the WA postcode area. Ring and ask instead of guessing when you are close to a county line, or anywhere awkward to explain.

A mobile service suits Netherton, a residential suburb: there's no need to bring the vehicle to us, because we drain it on the spot, on a drive, a residential street, a parking area or a forecourt.

What AdBlue in a diesel tank costs to put right in Netherton

There is no fair single quote, since the jobs are not the same. What changes the cost is, first of all, whether the engine has run and for how long; then how much AdBlue got in; and finally where the vehicle is and whether our van can reach it safely, which is easier on an open drive than in a tight spot behind Castle Park Arts Centre.

Ahead of any figure, not after, every call from Netherton begins with three questions: the fuel, the quantity, and whether the engine ran. Their replies shrink the range right down to one number.

Priced on the call before the engineer heads out, the job is paid for that day — card or phone, nothing in advance. Misfuelling cover is part of many insurance policies, so it is worth looking at yours before the van arrives.

Still alongside the car in Netherton?
