Read This canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/newtown-durham/ location: Newtown county: Durham latitude: 54.570360 longitude: -1.323400 service: AdBlue in a Diesel Tank updated: 2026-10-03 --- # AdBlue in a Diesel Tank in Newtown: Why It Happens and How to Avoid It Keep your engine and ignition off and phone 0333 366 0103 first — reading can wait when AdBlue is already in the diesel tank. Around Newtown, catching it before the engine turns usually leaves draining and a full flush on the spot. If you are reading before it has happened, the remainder of this page is about why it takes place and how to make sure it does not. ## Why does AdBlue in a diesel motor need its own filler? Plenty of newer diesels on the roads about Newtown and Stockton Grange carry two liquids, not one. Diesel goes to the motor. AdBlue goes to your exhaust, where it is sprayed into the gas to clean it, and it lives in a tank of its own. There is a filler for each tank. Under one flap, next to each other: that is the layout on a lot of motors. Elsewhere, AdBlue's filler is beneath the bonnet or in the boot instead. Topping up the diesel side at the pump happens constantly. Seldom filled, AdBlue normally comes from a bottle, tipped by a driver who has to stop and think which filler to use. Mistakes happen in the gap between them. ## Newtown: how AdBlue in your diesel tank takes place It is seldom carelessness. Three things tend to line up. Hurry follows from the warning. Your car tells you as AdBlue runs low, and an empty tank sends it into limp mode — so the top-up happens quickly, before work on a driveway off Wrensfield Road, or on the way home in the car park at The Station Free House. Then the car is unfamiliar. A hire car, a new car or a company car puts the fillers where your last one did not, and your hand gets to for the cap it would have used on the old one. Lastly, the bottle fits: diesel filler or AdBlue filler, it goes in just as easily, and once the tip begins, nothing halts it. It takes a few seconds, whether out in Primrose Hill or bang in the centre of Newtown. ## Which filler is for AdBlue, and which for diesel? Before you pour anything, whether on a driveway in Gilpin Brown or a forecourt in Newtown, check these. They take a couple of seconds. - Where it sits misleads; the cap doesn't. AdBlue ones tend to be blue or bear the name "AdBlue" — diesel ones usually do not. - On plenty of motors, size gives it away: AdBlue gets the smaller filler neck. - A label inside your fuel flap often shows which fuel goes where, on many cars. Check for it. - Cannot see it beside your diesel filler? Then look beneath the bonnet or in the boot — the handbook will say where. - Whoever had it before knows. Check as you collect a rental or company car — at Stockton's car park, perhaps — not once the light comes on. ## Keeping AdBlue out of the diesel tank when you top up On the day the warning appears — wherever it is in Durham — a simple routine to follow. - Park then switch off. Not on a slope, not with the motor running, and not in a rush on the side of Mellor Street. - Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds daft and it does the trick. - The two under one flap? Then confirm the lid 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, and check again — making sure your diesel filler stayed shut throughout. Only then, start the car. Stop there if you find, at stage two or three, that you have already poured into the diesel side. Never carry on to stage five. ## Put AdBlue in your diesel tank in Newtown already? Then the order of things is short. Don't start the engine. The fuel pump runs on plenty of diesels the moment the ignition goes on — so leave it off. Diluting it with extra diesel fails, since AdBlue settles to the bottom instead of mixing — and that's where the fuel is sucked from. Ask the attendants to help push your car clear of the petrol pump if you're at a forecourt — the Sainsbury's, the Esso or anywhere else. If you're on your own driveway around Newtown, leave the car where it sits. Stop as soon as it is safe then switch off, if your engine has already run. Newtown lies under 10 miles from the A1(M); on it, take the next exit. A short hop across Newtown is a smaller job than a run towards Durham, under 25 miles away, and so tell us about how far it went. ## When we arrive in Newtown, what takes place? By The Oak Tree Academy, near Newtown Community Resource Centre or on your own driveway: wherever the vehicle has stopped, our engineers come to it. The replies decide this work and the quote, and so our engineers ask what went in, roughly how much, and if it has run. During the call itself, you are told our price — before dispatch. Next: draining, then a thorough flush of the whole 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 that matters more with AdBlue than with petrol. Filter cleaned or, where it must be, swapped; fresh diesel in; then a check of your vehicle. Before we go, we start the engine and make sure that it's running correctly. With pumps fine on a busy forecourt and quiet enough for use outside a house at night, most jobs where the motor hasn't run need about half an hour once our technicians arrive. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Misfuelling cover is part of plenty of insurance policies — so make use of the wait to look at yours. ## About Newtown itself Newtown is a suburban area located on the riverside in County Durham, with a mix of terraced housing and local amenities.
