--- title: AdBlue in a Diesel Tank Adlington? Read This canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/adlington-lancashire/ location: Adlington county: Lancashire latitude: 53.617320 longitude: -2.597350 service: AdBlue in a Diesel Tank updated: 2026-10-16 --- # Preventing AdBlue in a Diesel Tank in Adlington: Why It Happens Leave the motor and ignition off then ring 0333 366 0103 now — reading can wait if AdBlue is already in the diesel tank. In Adlington, finding it before the engine runs usually means a drain and a full flush where it stands. Here before the event? Then the rest explains why it comes about and what to stop it happening at all. ## Why does AdBlue in a diesel car need its own filler? No single liquid but two: that is what plenty of newer diesels near Adlington and Rivington run, with diesel for your motor. Kept in a tank of its own, AdBlue is fed into the exhaust gas and cleans it. Each tank has its own filler. Many of vehicles have a single flap for both, while some put the AdBlue filler to the boot or under the bonnet. At the pump, your diesel side gets filled all the time. A driver who has to stop and work out where it goes normally fills the AdBlue side, from a bottle, and much less frequently. The mistake grows in that gap between the two. ## How does AdBlue in your diesel tank occur in Adlington? It's seldom carelessness. Three things tend to line up. To start with, the warning. Low AdBlue brings a warning from the vehicle, and running dry leads to limp mode — hence a rushed top-up, maybe before work off Railway Road, or at Elephant And Castle on the way home after work. Then, the hand goes for the cap it knew on the old car — since a hire car, a new motor or a company car places the fillers somewhere your last one did not. Third, the bottle goes in: a diesel filler or AdBlue one, it slides in just as readily, and once the pour begins, no part stops it. The same few seconds settle it, in the middle of Adlington or out in Anderton. ## How to tell the AdBlue filler from the diesel one Before you tip anything, whether on a driveway in Heath Charnock or a forecourt around Adlington, check these. They take a couple of seconds. - Check the cap instead of going by where it sits: AdBlue caps are commonly blue or marked "AdBlue", and diesel ones normally aren't. - On plenty of motors, the size gives it away: AdBlue gets the smaller filler neck. - The flap. Look inside your fuel flap for a label. Plenty of motors say there which fuel goes where. - The handbook says where it is when your filler isn't next to the diesel cap: the boot, or under the bonnet. - The person who drove the car last. On a hire or company car collected from somewhere like the car park at Adlington (Lancashire), ask before you leave, not when the light comes on. ## AdBlue top-ups that never reach your diesel tank On the day the warning comes on — wherever it is across Lancashire — a routine to follow. - Pull in somewhere level, engine off, with time to spare — not hurried on the side of Chorley Road. - Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds silly and it does the trick. - If both sit under one flap, check the diesel cap is still closed before you lift the bottle — and leave it on. - Tip slowly, using the bottle's own spout. Stop when it's full or when the bottle is empty. - Shut the cap, then check once more — making sure your diesel cap remained closed the whole time. Only then, start your car. Stop there if you find, at step two or three, that you have already poured into the diesel side. Do not go on to step five. ## Put AdBlue in your diesel tank in Adlington already? Then the order of things is short. Don't start the engine. Do not switch your ignition on; on plenty of diesels that alone runs the fuel pump. Thinning it with more diesel won't work, since AdBlue sinks to the base instead of mixing — and that's where your fuel is pulled from. At a forecourt — Essar, BP or another — the staff will usually help roll the vehicle clear, when you ask. If you're on your own driveway around Adlington, leave the car where it stands. Where your engine has run by now, pull over somewhere safe then switch the vehicle off. Adlington lies under a mile from the M61; there, take the first junction. Distance matters — a quick hop across Adlington makes a smaller job than heading under 15 miles towards Preston — so say roughly how far it went. ## What takes place when we arrive around Adlington By Anderton Primary School, close to The Parish Church of St Paul, Adlington or on your own driveway: wherever your car has stopped, our engineers come to it. What fluid got in, the quantity, and whether it ran: our engineers ask since those answers decide both work and quote. Nobody sets off before you have had our price over the phone. Draining the tank comes next, followed by a full flush of the system. AdBlue crystallises and is corrosive to some of the metals in a fuel system, and so it doesn't wash out on its own — which is why the flush matters more with AdBlue than with petrol. A test is last: before that, fresh diesel goes in, and the fuel filter is flushed or replaced if necessary. Before leaving, our engineers start it and check that it is running properly. If your engine hasn't run, most jobs take about half an hour once we're there, using pumps that are safe on a working forecourt and quiet enough to use outside a house after dark. No money upfront; you settle up that day. At the end, the VAT invoice and a report from the engineer go to you for your insurer. Misfuelling cover is part of plenty of insurance policies — so make use of the wait to check yours. ## About Adlington Adlington is a town situated on the riverside in Lancashire, with a population of around 8516 people.
