In Denstone, catching it before the engine runs normally means a drain and a full flush where it stands. Nothing happened yet? Below, the page explains the reasons it occurs and the ways to prevent it for good. ## AdBlue in a diesel car, and its separate tank Many current diesels on the roads around Denstone and Rocester carry two liquids, not one. Diesel goes to the engine. 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 on every tank. Under one flap, next to each other: that's the arrangement on many cars. On others, AdBlue's filler is under the bonnet or in your boot instead. At the pump, the diesel side gets filled all the time. The AdBlue side is topped up far less frequently, usually from a bottle, and usually by someone who has to stop and think where it goes. That gap is where the error lives. ## How does AdBlue in your diesel tank take place around Denstone? Three things tend to line up, and carelessness is seldom one of them. To start with, the warning. Low AdBlue triggers a message from your car, and running out means limp mode — so a rushed top-up, maybe before work off Denstone Lane, perhaps at The Tavern on the way home after work. Then your car is unfamiliar. A hire car, a new vehicle or a company car puts the fillers where your last one did not, and the hand reaches for the cap it would have used on the old one. Nothing halts the tip once it has started, since a bottle with a spout goes into a diesel filler as readily as an AdBlue one. The bottle fits. The same few seconds settle it, in the middle of Denstone or out in Quixhill. ## The AdBlue filler and your diesel filler: telling them apart Be it a Denstone forecourt or a drive over in Alders, take a few seconds on these before any goes in. - Where it sits misleads; the cap does not. AdBlue caps are often blue or carry the word "AdBlue" — diesel caps usually don't. - The size. On many vehicles the AdBlue filler neck is the smaller of the two. - Check inside the fuel flap: many cars carry a label there showing which fuel goes where. - The handbook. If the filler is not by the diesel cap, it's in your boot or under the bonnet, and the handbook says which. - The person who drove the car last. On a hire or company car collected from somewhere like the car park outside Uttoxeter, ask before you leave, not when the light comes on. ## Keeping AdBlue out of the diesel tank when you top up The day the light goes on, wherever in Staffordshire, use this routine. - Not in a rush on the side of Alton Road, not on a slope, not with the engine running: park then switch off properly. - Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds silly and it does the trick. - The diesel cap stays on. When the two share a flap, confirm it's closed before the bottle comes up. - Tip slowly, using the bottle's own spout. Stop when it is full or when the bottle is empty. - Only after that, start the car: close the cap, check again, and make sure your diesel cap was never opened. Find at step two or three that it's already gone into the diesel side? So stop right there. Stage five stays out. ## AdBlue in your diesel tank already, in Denstone? The short order of things, starting with no starting the motor. Keep your ignition off too, because on many diesels it alone starts your pump. AdBlue doesn't mix with diesel — it sinks to the bottom of the tank, where your fuel is pulled from — so do not top up with diesel to dilute it. On a forecourt — the nearest petrol station, Esso or any other — the attendants will normally help push the car clear, when you ask. Leave it where it is if you are on your own drive in Denstone. Already started? Stop once it is safe, then turn off. On the M6, under 15 miles from Denstone, that means the next junction. Roughly how far did it go? Hopping across Denstone is less a job than a run of under 15 miles towards Stoke-on-Trent, so tell us. ## When our technicians turn up in Denstone, what happens? Wherever the car came to rest, whether by All Saints CofE Academy Denstone, near All Saints or at home, our van travels to it. Our technicians ask what was put in, roughly how much, and if it has run, since those replies decide the work and the price. Nobody heads out before you have had the price by phone. After that: a drain, then a full flush of the whole system. More than with petrol, it counts here: the crystals form, certain metals corrode, and nothing washes out unaided, however long it sits. A test is at the end: before that, fresh diesel is added, and the fuel filter is cleaned or changed as needed. After that our engineers fire it up and make sure it runs smoothly before we go. Most jobs are done in about half an hour after our engineers get there, as long as the motor has not run — and the pumps we use are safe on a busy forecourt yet quiet at night outside a house. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. It's worth checking your insurance as the van travels to you: misfuelling cover is included with many policies. ## About Denstone, briefly Denstone is a village in Staffordshire, situated on the banks of a river at an elevation of 111 metres.
