--- title: AdBlue in a Diesel Tank Moorside? Read This canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/moorside-durham/ location: Moorside county: Durham latitude: 54.840630 longitude: -1.868540 service: AdBlue in a Diesel Tank updated: 2026-10-24 --- # How It Happens and How to Prevent It: AdBlue in a Diesel Tank in Moorside If AdBlue is already in your diesel tank, stop reading for a moment: leave your motor and the ignition off and ring 0333 366 0103. Caught before your engine runs, it's generally a drain and a thorough flush, done where the car is around Moorside. If you're reading before it has happened, the rest of this page is about why it happens and how to make sure it doesn't. ## Two fillers, two tanks: AdBlue in a diesel motor Diesel goes to your engine — yet plenty of current diesels seen around Moorside and Rowley carry another liquid too. Its own tank keeps it, and from there it is sent to the exhaust, and there a spray treats the fumes. Each tank has its own filler. Under one flap, side by side: that is the arrangement on many motors. Elsewhere, AdBlue's filler sits under the bonnet or in your boot instead. Topping up your diesel side at the pump happens all the time. Seldom filled, AdBlue usually goes in from a bottle, poured by a driver who must stop and think which filler it needs. Mistakes happen in that gap between them. ## Moorside: how AdBlue in your diesel tank takes place Seldom is it carelessness: usually three things coincide. On a drive off Dunelm Road before work, or in the car park outside THe Horse & Groom on the way home: that's where the hurried top-up takes place. What is the reason for the rush? As AdBlue gets low your car warns you, and once it is gone, limp mode kicks in. Then the car is unfamiliar. A hire car, a new motor or a company car puts the fillers where your last one didn't, and the hand hits for the cap it would have used on the old one. No part stops the tip after it has started, because a bottle with a spout goes into a diesel filler as easily as an AdBlue one. The bottle fits. The same few seconds settle it, in the middle of Moorside or out in Allensford. ## How to tell the AdBlue filler from the diesel one Before you tip anything, whether on a drive in Bridgehill or a forecourt in Moorside, check these. They take a few seconds. - Where it sits can mislead; the cap doesn't. AdBlue caps tend to be blue or bear the name "AdBlue" — diesel ones usually don't. - On plenty of vehicles, size gives it away: AdBlue has the smaller filler neck. - Check inside the fuel flap: plenty of cars carry a label there showing which fuel goes where. - Cannot see it beside your diesel inlet? Then look below the bonnet or in the boot — the owner's manual says where. - The person who drove it last. On a hire or company car collected from somewhere like the car park at Stocksfield, ask before you leave, not when the light comes on. ## Topping up AdBlue without it reaching the diesel tank On the day the light appears — wherever you are around Durham — a simple routine to use. - Stop on level, motor off, with time to spare — never hurried on the side of Sussex Road. - Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds daft and it works. - Both behind a single flap? Then confirm the cap on the diesel filler stays shut before lifting the bottle. - Pour slowly, using the bottle's own spout. Stop when it's full or when the bottle is empty. - Before starting the car, shut the cap and check again that the diesel cap never came off. Find at the second or third step that AdBlue went into the diesel filler? That's where you stop. Never go on to step five. ## AdBlue in the diesel tank already, in Moorside? Then the order of things is short. Don't start your engine. On many diesels the ignition alone runs the fuel pump, so do not switch the car on. Filling up with diesel will not weaken it: instead, AdBlue drops to the base of that tank, right where fuel is taken from. The staff at Tesco, Morrisons or another forecourt will usually help to push the vehicle away when asked. Leave it where it is if you are on your own driveway in Moorside. Already started? Stop once it's sensible, then switch off. Moorside sits under 15 miles from the A1(M); there, take the first junction. Mileage counts — a short hop across Moorside makes a smaller job than heading under 15 miles to Durham — so tell us roughly how far it went. ## Moorside: what takes place when our engineers get there The van comes to your car wherever it stopped — your own drive, beside St. Pius X Catholic Church, or by Moorside Primary Academy. Which liquid was put in, the quantity, and if it ran: our technicians ask since those answers set both work and price. You get that quote on the phone, before anybody sets off. Then your tank is drained and the system purged thoroughly. Unlike petrol, AdBlue forms crystals and eats at some fuel-system metals, and neither washes away unaided. That is why it matters more. After the fuel filter has been flushed — or renewed, where required — clean diesel goes in, and then the car gets tested. We do not leave until it has been started and is running smoothly. Unstarted cars mostly need a half-hour job after the moment we arrive. The equipment is safe on a live forecourt, and hushed enough for a driveway late at night. Nothing upfront; you settle up that day. At the end, a VAT invoice and the report from the engineer go to you for your insurer. Before we get there, take a look at your policy; plenty include cover for misfuelling. ## About Moorside Moorside is a suburban area situated on the riverside in County Durham, with a mix of semi-detached housing and a population of around 2209 residents. Moorside sits at an elevation of 174 metres, approximately 12 miles from the city of Durham and 241 miles from London. Moorside is located near other local places such as Allensford, The Grove, and Castleside, in the North East region of England. Moorside has a relatively small and quiet community, typical of many suburban areas in the region. ## Moorside and Durham: AdBlue drains across the area Throughout DH postcodes, our vans covering Moorside — a residential suburb — work the nearby spots too, Castleside and The Grove among them. A postcode starting DH8 8 gets the van to you fastest. Your car does not need to move. Draining happens right there, whether a drive, a street near The Grove Methodist Church, or a layby on the way to Allensford Wood Local Nature Reserve. Ring and ask instead of guessing if you're near a border, or somewhere hard to explain, like the back of Castleside Village Hall. ## In short, for Moorside people Before you tip, read the cap. If AdBlue has gone in your diesel tank anyway, leave the vehicle off and phone 0333 366 0103. Petrol in Diesel clears it where it waits, anywhere in Durham.
