Stop reading a minute if your diesel tank already holds AdBlue in it: ignition off, engine off, and phone 0333 366 0103. A drain plus a full flush, done just where the vehicle stands around Stainton, is usually what it needs when caught before the motor runs. Nothing happened yet? Below, the rest of the page explains the reasons it occurs and the ways to avoid it altogether. ## Two fillers, two tanks: AdBlue in a diesel motor Not one liquid but two: that's what plenty of modern diesels near Stainton and Maltby run, with diesel feeding the engine. The exhaust, not the motor, is where AdBlue ends up: dosed into the fumes to fresh it, from its own tank. There's a filler for every tank. Under one flap, next to each other: that's the layout on a lot of motors. On others, AdBlue's filler sits under the bonnet or in the boot instead. Diesel gets filled at each filling station visit, again and again. The AdBlue side is filled far less often, usually from a bottle, and usually by somebody who has to stop and think where it goes. The mistake grows in that gap between the two. ## How does AdBlue in your diesel tank occur around Stainton? Carelessness seldom explains it. What does is three things lining up together. On a drive off Hemlington Road before work, or in the car park at The Stainton on the way home: that's where the hurried top-up happens. What is the reason for the rush? As AdBlue gets low the car warns you, and if it is gone, limp mode follows. The old car's cap is where the hand goes — yet a hire car, a new motor or a company car puts the fillers somewhere else. That is a second factor: a strange car. And the bottle fits. A bottle with a spout goes into a diesel filler as easily as an AdBlue one, and so nothing stops the tip once it has started. The same few seconds settle it, in the middle of Stainton or out in Thornton. ## How to tell the AdBlue filler from the diesel one Be it a Stainton forecourt or a driveway over in Acklam, spend a few seconds on these before any goes in. - Check the cap instead of going by position: AdBlue ones are often blue or marked "AdBlue", and diesel ones normally aren't. - Look at the size: the smaller neck is, on many cars, the AdBlue one. - Lift the flap and look for a label — many cars mark which goes in which inlet right there. - The handbook shows which it is if the filler isn't next to your diesel cap: your boot, or under the bonnet. - Picking up a hire or company car, say at the car park outside Marton? Check with the person who drove the vehicle last before you set off, not when the light comes on. ## Keeping AdBlue out of the diesel tank when you top up Anywhere in North Yorkshire the light comes on, here is a routine for that day. - Park and switch off. Not on a slope, not with your engine running, and not in a rush on the side of Kelgate Terrace. - Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds daft and it works. - The two behind one flap? Then make sure the cap on your diesel side is still shut before lifting the bottle. - Tip slowly, using the bottle's own spout. Stop when it's full or when the bottle is empty. - Only then, start the vehicle: close the cap, check once more, and make sure your diesel cap was never opened. If at step two or three you find you have already poured into the diesel side, stop there. Step five stays out. ## Stainton: already put AdBlue in the diesel tank? The short order of things, starting with not starting the motor. Leave your ignition off as well, because on many diesels it alone starts your fuel pump. Do not top up with diesel to thin it: AdBlue does not mix with diesel, it sinks to the bottom of that tank, where the fuel is pulled from. The attendants at Esso, Shell or another forecourt will usually help to push the vehicle away if you ask. Your own driveway around Stainton is the place it should stay. When the motor has run already, pull over safely then switch the car off. The next junction is the place to come off when you're on the A1(M), under 15 miles from Stainton. Distance counts — a short hop across Stainton makes a smaller job than driving under 25 miles to Durham — so say roughly how far it went. ## When our engineers get there around Stainton, what takes place? Wherever your car has stopped, be it outside Hemlington Hall Academy, beside St Peter & St Paul or on your own drive, the van comes to it. We ask what was put in, about how much, and whether it's run, because those replies determine this work and our price. You get that quote by phone, before anybody sets off. Your system is then purged thoroughly, after that tank is emptied. More than with petrol, it counts here: the crystals form, certain metals are attacked, and nothing washes away unaided, however long it sits. Testing comes at the end: before that, clean diesel is added, and your filter is cleaned or replaced as needed. Next we start the engine and make sure it runs properly before we leave. Unstarted cars usually mean a half-hour visit after the moment we arrive. The kit is safe on a busy filling station, and quiet enough for a residential street after dark. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. It is worth checking your policy while we travel to you: misfuelling cover comes with plenty of policies. ## About Stainton itself Stainton is a village in North Yorkshire, situated on the riverside at an elevation of 46 metres, with detached housing being the predominant type of accommodation.
