--- title: Killingworth Moor: AdBlue in a Diesel Tank, Explained canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/killingworth-moor-tyne-and-wear/ location: Killingworth Moor county: Tyne and Wear latitude: 55.028220 longitude: -1.555700 service: AdBlue in a Diesel Tank updated: 2026-10-22 --- # Preventing AdBlue in a Diesel Tank in Killingworth Moor: Why It Happens If AdBlue is already in your diesel tank, stop reading for a moment: leave the motor and the ignition off then phone 0333 366 0103. A drain plus a full flush, carried out just where the vehicle sits in Killingworth Moor, is usually all it takes when found before the engine runs. Reading in advance? In that case the rest covers how it happens and what to prevent it happening at all. ## AdBlue in a diesel motor: two tanks, two fillers Diesel feeds your motor — yet plenty of current diesels driven about Killingworth Moor and Longbenton carry a second fluid as well. AdBlue goes to your exhaust, where it is sprayed into the gas to fresh it, and it lives in a tank of its own. Separate tanks, separate fillers. Many of motors share a single flap for both, whereas some put the AdBlue filler to the boot or under the bonnet. At the pump, the diesel side is topped up constantly. The AdBlue side is filled far less often, normally from a bottle, and normally by someone who has to stop and think where it goes. Mistakes happen in the gap between them. ## AdBlue in the diesel tank around Killingworth Moor: how it happens Three things tend to come together, and carelessness is seldom one of them. To start with, the warning. Low AdBlue brings a warning from the vehicle, and letting it run dry leads to limp mode — hence a rushed top-up, maybe before work off Woodlands Grange, or at Forest Hall Workmen's Social Club on the way home after work. Then the vehicle is new. A hire car, a new vehicle or a company car puts the fillers where your last one didn't, and your hand gets to 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. Whether it occurs in Killingworth Village or the middle of Killingworth Moor, it's the same few seconds. ## How to tell the AdBlue filler from the diesel one Be it a Killingworth Moor forecourt or a driveway over in Killingworth, take a few seconds over these before anything is poured in. - Read the cap instead of going by position: AdBlue caps are frequently blue or marked "AdBlue", and diesel caps usually are not. - Check the size: the smaller filler neck is, on plenty of motors, the AdBlue one. - Lift the flap and look for a label — many motors mark what belongs in which inlet right there. - The handbook shows where it lives if your filler is not next to the diesel cap: your boot, or under the bonnet. - The previous driver will know. Ask when you pick up a rental or fleet car — at Seaton Delaval's car park, say — rather than once the warning appears. ## How to top up without AdBlue in your diesel tank For the day the light comes on — anywhere you are around Tyne and Wear — a routine to use. - Not in a rush on the side of Nicholson Terrace, not on a slope, not with your engine running: park and switch off first. - Silly as it sounds, saying "AdBlue" out loud while you unscrew the cap does the trick — once you've located your filler and read it. - The two behind one flap? So confirm the cap on your diesel side is still shut before raising the bottle. - Using the bottle's own spout, tip slowly — and stop when it's full or the bottle is empty. - Close the cap, then check once more — confirm your diesel filler remained closed throughout. After that, start your car. Stop there if you find, at stage two or three, that you've already poured into your diesel side. Leave out stage five entirely. ## Already put AdBlue in your diesel tank around Killingworth Moor? Then the order of things is short. Do not start your motor. The fuel pump runs on many diesels the moment the ignition goes on — and so leave it off. Thinning it with extra diesel won't work, since AdBlue sinks to the bottom instead of mixing — and that's where your fuel is drawn from. At a forecourt — Morrisons, Asda or any other — the staff will normally help roll the vehicle away, if you ask. On your own drive around Killingworth Moor? So the car stays put. If the motor has already run, stop as soon as it is safe and switch off. The next junction means the place to come off if you're on the Clayton Road, under 5 miles from Killingworth Moor. Mileage counts — a short hop across Killingworth Moor is a smaller job than driving under 5 miles towards Newcastle upon Tyne — so say about how far it went. ## When we get there in Killingworth Moor, what happens? By St Marys Catholic Primary School, Forest Hall, near Killingworth Colliery Shaft or on your own driveway: wherever the car has stopped, our engineers come to it. The replies settle this work and the quote, so we ask what was put in, roughly how much, and if it has run. You get that quote by phone, before anyone heads out. Draining your tank comes next, followed by a thorough flush of your system. Unlike petrol, AdBlue leaves crystals and attacks certain fuel-system metals, and none of that washes away unaided. That is why it matters more. The fuel filter is flushed, or replaced where it needs to be; clean diesel goes in; and your car is tested. Before we go, our technicians fire it up and confirm that it's running correctly. Unstarted cars usually mean a half-hour job from arrival. The kit is fine on a live filling station, and quiet enough for a residential street late at night. Nothing in advance; you settle up on the day. Afterwards, a VAT invoice and the report from the engineer are handed to you for the insurer. While we travel, take a look at your insurance documents; plenty include cover for misfuelling. ## About Killingworth Moor Killingworth Moor is a locality situated on the riverside in Tyne and Wear, with an elevation of around 60 metres.
