Shenstone: AdBlue in the Diesel Tank? Leave It Off

AdBlue in your diesel tank? Then keep your motor off — and your ignition too. Water with urea dissolved in it: that is AdBlue. The harm starts once it's pulled through your lines — it won't burn, and it won't combine with diesel. If your engine hasn't run yet, AdBlue in a diesel tank is generally drained and carefully rinsed where your car sits in Shenstone. First, call us on 0333 366 0103.

Your next steps right now, Shenstone: AdBlue in your diesel tank

Things to do:

  • So no one can turn your ignition on, pull your keys out.
  • Close to moving traffic? Then put your hazards on.
  • Hold on to the till receipt or the empty bottle, so you can tell us what was put in and roughly how much.
  • Give us a postcode starting WS14 0, or whichever street is closest, and our van reaches you straight — so call wherever you stand.

Do not do these:

  • Don't start the motor, even for a moment to shift the car.
  • Do not switch the ignition on. On many diesels that alone runs the fuel pump.
  • Don't top up with diesel to dilute it. AdBlue doesn't mix in diesel; it separates out.
  • Any driving at all is best avoided, even a short way up Lynn Lane.
  • Draining that tank on your own beside the road isn't one to try.

At a forecourt in Shenstone, whether it is the Esso or another one, ask the attendants to help you roll the vehicle away from the petrol pump. On your own driveway, do not touch it at all.

AdBlue in a diesel tank, and what it does there

The engine isn't what AdBlue is made for; your exhaust is. Its own tank holds it, and from there it is sprayed into your exhaust, where it cleans the gas. Neither side suits the other: urea does not belong in an injection pump, and a pump cannot deal with urea.

It does not combine. Once it's poured into a tank of diesel, AdBlue acts not at all like fuel. Denser than diesel, it drops and collects underneath it — the same spot the pickup sucks from. A car filled on a driveway in Little Hay yesterday evening and not started since counts as the simple case. No pump has pulled the AdBlue up so far — though when your engine runs, that's what is pulled first, straight from the bottom of that tank.

It causes two kinds of damage from there. Crystals and corrosion. As the water evaporates, it leaves urea that hardens in filter elements and tiny channels; and, because it attacks certain metals, every part it reaches keeps suffering for as long as it stays in there. Lines holding AdBlue spell harm overnight for a car parked around Shenstone. Just in the tank, it stays the same. Diesel protects the high-pressure pump and every injector as it flows; water gives no lubrication, which is a separate form of harm.

Draining AdBlue from a diesel tank in Shenstone

AdBlue in a diesel: why it is frequently worse than petrol

Top up a diesel with petrol in error at the Shell, and this problem is diluted fuel. Harm only comes from running on it. Mixed into your diesel and left in the tank, it causes none.

AdBlue in a diesel is a fault of the wrong substance altogether. Not burning, it cannot simply be run through. Nor can it be watered down, because it separates back out — and the next tankful will not rinse away deposits or corrosion. So the flush matters more with AdBlue, and trying your engine "to see", in the centre of Shenstone or out in Lynn, does more harm than almost any other error.

The same good news applies as with petrol. If your motor has not run, the AdBlue is still in your tank, and that tank is the quickest part of a fuel system to clear, wherever across Staffordshire the car is sitting.

AdBlue in a diesel tank around Shenstone: how it ends up there

It is not on purpose. Many vehicles have the AdBlue cap beside the diesel one, now and then under a single flap, and muddling them up is easy after dark. A bottle picked up while heading home and tipped in at home, instead of at the forecourt, is the typical route.

A couple of familiar ways cover the majority of them. Halfway through the morning drop-off, the dashboard flags it up, and outside Greysbrooke Primary School the top-up is hurried. A bottle is poured in at the end of the day on a drive just off Pinfold Hill. Or someone unfamiliar with that flap tops up the car in dim light, parked in the car park by The Railway Inn.

The least familiar vehicles get it most — hire cars, brand-new cars, fleet ones, and the other motor of a family with both fuel types. Wherever you're in Shenstone or the rest of Staffordshire, it's the same slip and the same first answer: leave the vehicle off.

Started the engine with AdBlue in your diesel tank around Shenstone?

Then the AdBlue has left the tank. Your filter and pipework have had it pulled along, and any running carries it on to the high-pressure pump and every injector.

Perhaps returning from Shenstone Playing Fields, or part way across Shenstone, your engine may go lumpy, smoke, lose pace, light up your dash or cut out. No restarting to test: stop once safe, then turn everything off. Each start pulls more of it through.

If you were on the M6 Toll, under a mile from Shenstone, come off at the next exit and stop somewhere sensible rather than pressing on.

Mileage counts: every mile pushes the AdBlue further in, so driving for Lichfield, under 5 miles away, gives a far larger job than crossing Shenstone to the car park by Wesley Hall. Let us know roughly how far it had come.

Once your engine has been run, the flush covers more, and all of it is done where your car has stopped. Noticed soon, it very rarely leaves permanent damage.

Shenstone: how AdBlue is emptied from a diesel

Anywhere it has come to rest in Shenstone — a forecourt, a lay-by, a driveway, a street by Trinity Methodist Church — our van comes to your car. Which fluid went in, about the quantity, plus if your engine has turned over: our technicians ask first, since those shape the job.

On the spot, that tank is then emptied, and both the polluted diesel and the urea come out at once. The fuel system is flushed thoroughly, which counts more with AdBlue than with petrol, because what it leaves behind doesn't rinse out on its own. A test of your car comes last, once fresh diesel goes in and the fuel filter is flushed or, where necessary, swapped. Roughly half an hour once we arrive is typical for most jobs where your engine has not run. Our pumping gear is explosion-proof, so a busy filling station is no problem, and it's quiet enough for a residential street after dark.

Last, the fuel system is bled with fresh diesel. Whether it's a parking space outside the nearest station or a drive around Shenstone, that is where our engineers fire it up and you set off. It's checked on new diesel to confirm it runs smoothly before our engineers leave. No garage is required at any stage, with the whole job done then and there. You receive a VAT invoice and an engineer report after that, which is what insurers ask for.

About Shenstone, for a moment

Shenstone is a village in Staffordshire, situated on the banks of a river at an elevation of around 102 metres. Shenstone lies approximately 3 miles from the city of Lichfield and 106 miles northwest of London. Shenstone has a mix of old and new housing, with detached homes being the predominant type. Shenstone is close to nearby places such as Chesterfield, Footherley, and Wall.

AdBlue drains across Staffordshire, Shenstone included

Chesterfield, Footherley and Wall are among the places around Shenstone that the same vans serve, along with most of Staffordshire beyond, over the WS postcode area. Near a border, or anywhere tricky to explain? Checking is better than assuming, and so phone.

Shenstone 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 sits, and so it never needs to be moved to us.

What does AdBlue in a diesel tank cost to sort out around Shenstone?

Not one single figure could be honest, because each job is different. The cost shifts first with how long, if at all, the motor has been running, and next with the amount of AdBlue that was put in. After that it depends on where your car is and whether our van can reach it safely, which is easier on an open drive than in a tight space behind Shenstone Community Library and Coffee Shop.

Which fluid got in, how much, and if it ran: every Shenstone enquiry opens with precisely that, before a quote, not afterwards. Those answers shrink the range right down to a single number.

Before a van heads out, you hear the quote on the phone. And you pay on the day, by card or by phone, with nothing in advance. Misfuelling cover comes with many insurance policies, so it is worth looking at yours before the van arrives.

Shenstone: still alongside the car?

In that case, do nothing — that's the best step available. Motor off, keys out, ignition off. Petrol in Diesel takes over the remainder, in Shenstone or anywhere in Staffordshire, after you call 0333 366 0103 to say it was AdBlue, about what quantity, and whether the engine ran.
