Read This canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/hawkshaw-lancashire/ location: Hawkshaw county: Lancashire latitude: 53.707520 longitude: -2.482950 service: AdBlue in a Diesel Tank updated: 2026-10-20 --- # AdBlue in a Diesel Tank in Hawkshaw: How It Occurs and How to Avoid It AdBlue already in the diesel tank? In that case set this page down a moment, leave your ignition and motor off, and ring 0333 366 0103. A drain plus a thorough flush, done right where the vehicle stands around Hawkshaw, is normally all it takes if caught before the motor runs. If you are reading before it has happened, the rest of this page is about why it happens and how to make sure it does not. ## AdBlue in a diesel motor: two tanks, two fillers Plenty of modern diesels in Anchor, as well as Hawkshaw, run on two fluids; the engine takes only the diesel. Stored in a tank of its own, AdBlue is fed into your exhaust stream to clean it. Every tank has one filler of its own. Under one flap, next to each other: that's the layout on many motors. On others, AdBlue's filler is under the bonnet or in your boot instead. Topping up your diesel side at the petrol pump happens constantly. The AdBlue side is filled far less often, usually from a bottle, and normally by a person who has to stop and think where it goes. It's in that gap that the error happens. ## Hawkshaw: how AdBlue in your diesel tank takes place It's hardly ever carelessness. Three things tend to line up. To start with, the warning. Low AdBlue brings a warning from the car, and running out leads to limp mode — so a rushed top-up, maybe before work off Hartington Road, or at Anchor Hotel on the way home that evening. New-to-you motors come second, too. Hire cars, new cars and company motors place their fillers in new places, and habit reaches for the cap it used on the old one. Third, the spout fits: diesel filler or AdBlue one, it slides in as readily, and once the pour begins, nothing stops it. It's a few seconds, be it out in Birch Hall or right in the heart of Hawkshaw. ## How to tell the AdBlue filler from the diesel one Be it a Hawkshaw forecourt or a drive over in Moss Bridge, take a couple of seconds over these before anything goes in. - Position misleads; the cap does not. AdBlue ones tend to be blue or bear the word "AdBlue" — diesel caps usually don't. - Plenty of motors fit AdBlue the smaller neck of the two. - The flap. Look inside your fuel flap for a label. Many cars say there which fuel goes where. - The handbook says which it is if your filler is not next to your diesel cap: the boot, or under the bonnet. - The person who drove it last. On a hire or company car picked up from somewhere like the car park outside Darwen, ask before you leave, not when the light comes on. ## AdBlue top-ups that never reach your diesel tank On the day the light comes on — wherever you are around Lancashire — a simple routine to use. - Park then switch off. Not on a slope, not with the motor running, and not in a rush on the side of Lynwood Avenue. - Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds silly and it works. - Leave your diesel cap on. If both sit under one flap, check the diesel cap is still closed before you lift the bottle. - Using the bottle's own spout, pour slowly — and stop when it's full or the bottle is empty. - Only then, start the vehicle: close the cap, check once more, and make sure the diesel cap was never opened. If at stage two or three you find you have already poured into the diesel side, stop there. Do not go on to stage five. ## AdBlue in your diesel tank already, around Hawkshaw? The short order of things, beginning with no starting your engine. Don't switch the ignition on; on many diesels that alone runs the fuel pump. Do not top up with diesel to dilute it: AdBlue does not mix with diesel, it sinks to the bottom of your tank, where the fuel is drawn from. The staff at Shell, Texaco or another forecourt will normally help to push your car clear when asked. Leave it where it is if you are on your own drive around Hawkshaw. When the motor has been run already, stop somewhere safe then turn the car off. Hawkshaw lies under a mile from the M65; there, take the next exit. A short hop across Hawkshaw is a smaller job than a run towards Preston, under 10 miles away, and so tell us about how far it went. ## When we get there around Hawkshaw, what happens? Anywhere the vehicle has stopped, be it by St Cuthbert's Church of England Primary School, beside St Cuthbert's Church or at home, the van comes to it. Our technicians ask what got in, about how much, and if it's run, since those replies decide this work and our price. That quote is given on the call, ahead of any van leaving. The system is then cleaned thoroughly, after the tank is emptied. With AdBlue that counts more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, and so it doesn't wash out on its own. Testing is at the end: before that, clean diesel is added, and the filter is cleaned or replaced as needed. Before we go, our technicians fire it up and confirm that it's running smoothly. With pumps safe on a working forecourt and quiet enough to use outside a house at night, most jobs in which the motor has not run need roughly half an hour once our engineers are there. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Many insurance policies include misfuelling cover, and so it's worth checking yours whilst we're on the way. ## About Hawkshaw, for a moment Hawkshaw is a suburban area in Lancashire, situated on the riverside at an elevation of 159 metres, with terraced housing being the predominant type of accommodation.
