--- title: Smallwood Hey: AdBlue in a Diesel Tank? Don't Start canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/smallwood-hey-lancashire/ location: Smallwood Hey county: Lancashire latitude: 53.926320 longitude: -2.924170 service: AdBlue in a Diesel Tank updated: 2026-10-15 --- # AdBlue in the Diesel Tank in Smallwood Hey? Keep It Switched Off Engine off, ignition off: that's where you start if AdBlue has gone into the diesel tank. AdBlue is urea mixed in water. Not like fuel, it neither burns nor blends, and nothing happens until your motor pulls it through. Caught before the motor has run, AdBlue in a diesel tank is normally a drain and a thorough flush, done where the vehicle is in Smallwood Hey. Nothing comes before calling 0333 366 0103. ## Your next steps straight away, Smallwood Hey: AdBlue in your diesel tank Things to do: - Remove your keys, and that prevents anyone switching the power on. - Put your hazards on if you're anywhere near moving traffic. - The empty bottle or your receipt tells us the product and the amount, so do not bin it away. - Our van locates you fastest with a postcode starting PR3 6, or just the name of a street nearby, so call from the spot. Don't: - Do not start your engine, even for a moment to shift the vehicle. - Don't switch the ignition on. On plenty of diesels that alone runs the fuel pump. - Don't top up with diesel to dilute it. AdBlue does not mix in diesel; it separates out. - Leave the vehicle where it is instead of driving it anywhere, even a short way up Shaws Lane. - No emptying it yourself, at all, at the verge. Moving the vehicle off the island is a job for staff to help with, whichever Smallwood Hey forecourt you're on, the Asda included. If you're on your own drive, leave it precisely where it is. ## AdBlue in a diesel tank, and what it does there Not the engine but the exhaust is where AdBlue is meant to go. Its own reservoir holds it, and from there it's fed into your exhaust, where it cleans the fumes. Nothing in it is supposed to pass through a fuel pump, and nothing in a fuel pump is made to handle it. It doesn't combine. Once it is tipped into the tank, AdBlue acts nothing like fuel. It's heavier than diesel, and so it sinks and gathers at the bottom of that tank, which is where the pickup draws fuel from. The first thing your fuel system pulls through, after it runs, is the AdBlue. So a car that had AdBlue poured in on a drive in Stake Pool last night, and has not been started since, is still the straightforward case: the AdBlue is lying at the bottom of that tank, and nothing has sucked it in. Two kinds of damage follow from there. What is left once the water goes is urea, which turns into crystals: they lodge in tiny channels and block filters. Worse, it eats at certain metals in the fuel system, and keeps going till it's flushed out. If the AdBlue is in the pipework, leaving it till morning around Smallwood Hey leaves it worse. In your tank only, time costs nothing. Then there is the water: it brings no lubrication to the components that rely on it most — the injection pump and each injector. ## Why AdBlue in a diesel is regularly more serious than petrol Petrol pumped into a diesel on Texaco's forecourt makes your fuel watery — that is the main problem. Damage only comes from running on it. Blended into the diesel and sitting in your tank, it causes nothing. AdBlue in a diesel is a different problem: not thin fuel, yet no fuel at all. It does not burn, so it can't simply be run through. Whether the vehicle sits in Scronkey or the centre of Smallwood Hey, firing it up "to see" does more harm in this case than nearly any other error, and the flush counts for more. The reasons: it won't stay blended, so diluting it is impossible; and crystals and corrosion survive the following tankful. The same good news holds as with petrol. Clearing a tank is the easiest part on a fuel system, and without running, the AdBlue remains in there — wherever across Lancashire the car has stopped. ## Smallwood Hey: how AdBlue ends up in a diesel tank It's not on purpose. Many vehicles keep the AdBlue inlet beside the diesel inlet, occasionally behind one flap, and mixing them up is simple after dark. A container bought when driving home and tipped in at home, rather than at the filling station, is the typical route. The ways it happens are few and familiar. Halfway through the morning drop-off, the dashboard warns, and outside Pilling St John's Church of England Voluntary Aided Primary School the top-up is rushed. Close to Wheel Lane, someone pours a container in on the drive after work. Another pattern: dim light, a pub car park outside Golden Ball, and someone using that flap for the first time. It comes up most in a rental, a new car, a fleet motor, or the other motor of a family with both fuel types — the vehicles people know the least. Keep it off: that's the first response to the same slip, anywhere around Smallwood Hey or the remainder of Lancashire you are. ## Started your engine with AdBlue in the diesel tank in Smallwood Hey? If so, the AdBlue is no longer inside that tank. Via the fuel filter, along the lines, and — given any running — into the high-pressure pump and each injector: that's how far it has gone. You may notice your motor running unevenly, smoking, losing power, showing warning lights or cutting out, possibly on the way back from Lane Ends Amenity Area or halfway across Smallwood Hey. When safe, pull over and turn everything off — without restarting to test. Each start pulls more of that through. If you were on the M6, under 10 miles from Smallwood Hey, come off at the next exit and stop somewhere safe instead of pressing on. How far it went matters. A few hundred yards across Smallwood Hey to the car park by Pilling Methodist Church is a very different job from a run towards Lancaster, under 10 miles away, with the AdBlue reaching further into your system with each mile. Let us know about how far it had come. Once your engine has been started, the flush covers more, and all of it is done where the car has come to a stop. Very seldom does it leave permanent damage if it is spotted quickly. ## Smallwood Hey: how AdBlue is emptied from a diesel Our technicians come to the vehicle, wherever it has stopped around Smallwood Hey: a side street close to St John The Baptist, a drive, a lay-by or a forecourt. The job rests on three answers, which our technicians ask for first — which fluid went in, the amount, and if the engine has run. On the spot, that tank is then emptied, and both the polluted diesel and the urea leave as one. A careful flush matters far more with AdBlue than after petrol, since residue won't clear out by itself. Fresh diesel goes in once the filter is flushed — or replaced, if it needs to be — and after that your vehicle is tested. If your motor hasn't run, the majority of jobs take about half an hour once our technicians arrive. Explosion-proof pumps mean a live forecourt safe to work on, and they're quiet enough not to disturb the street at night. Bleeding the fuel system with new diesel comes at the end. Whether it is a parking bay at Poulton-Le-Fylde or a driveway in Smallwood Hey, that is where we start the engine and you drive off. It's checked on new diesel to make sure it runs correctly before our technicians head off. As the job is done in its entirety where your car is, a garage never comes into it. You get a VAT invoice and an engineer report later on, which is what insurers want. ## About Smallwood Hey Smallwood Hey is a coastal village in Lancashire, situated near the cities of Lancaster and Preston.

Whether the motor has run, and for how long, comes first in what moves the cost. How much AdBlue went in comes next, and then the position of the car, since an open drive is easier for our van to reach safely than a tight gap behind Pilling Village Hall.

The quote is quoted during the call, before anyone sets off; payment comes on the day, by card or over the phone, and nothing upfront. Look at your insurance while we're on the way: plenty include misfuelling cover. ## Still beside the car in Smallwood Hey? Then the most handy thing you can do is nothing to the vehicle. Keys out, motor off, ignition off. Petrol in Diesel takes over the rest, across Smallwood Hey or anywhere in Lancashire, once you call 0333 366 0103 to say it was AdBlue, roughly what quantity, and whether the engine ran.
