In Crofts Bank, catching it before your engine turns normally means a drain and a full flush on the spot. Here in advance? Then the rest explains how it happens and what to stop it happening at all. ## AdBlue in a diesel vehicle: two tanks, two fillers Plenty of modern diesels on the roads about Crofts Bank and Flixton carry two liquids, not one. Diesel goes to the engine. Its own tank holds it, and from there it goes to the exhaust, and there a spray treats the fumes. Each tank has its own filler. Plenty of motors share a single flap for both, whereas others put the AdBlue filler to the boot or under the bonnet. The diesel side is filled at the pump all the time. The AdBlue side is filled far less frequently, usually from a bottle, and usually by someone who has to stop and think where it goes. Mistakes happen in that gap between the two. ## Crofts Bank: how AdBlue in the diesel tank occurs Carelessness seldom explains it. What does is three things coming up at once. The warning comes first. As AdBlue runs low the vehicle tells you, and if it runs out completely, the vehicle drops into limp mode. So the top-up is done in a hurry: on a driveway off Bowers Avenue before work, or in the car park at The Bent Brook on the way home. Then the vehicle is unfamiliar. A hire car, a new car or a company car puts the fillers where your last one did not, and the hand gets to for the cap it would have used on the old one. 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 after it has started. Davyhulme or the middle of Crofts Bank: it is the same few seconds either way. ## Which filler is for AdBlue, and which for diesel? Before you pour anything, whether on a driveway in Woods End or a forecourt around Crofts Bank, check these. They take a few seconds. - The cap. The AdBlue cap is often blue, or marked "AdBlue". Your diesel cap usually is not. Read it instead of going by where it sits. - Many motors give AdBlue the smaller filler of the two. - The flap. Look inside your fuel flap for a label. Many cars say there which fuel goes where. - The handbook. If the filler is not by your diesel cap, it's in the 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 at Chassen Road, ask before you leave, not when the light comes on. ## Topping up AdBlue without it reaching your diesel tank On the day the warning appears — wherever it is around Greater Manchester — a simple routine to follow. - Stop somewhere level, engine off, with time to spare — not hurried on the side of Vicarage Road. - Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds silly and it works. - If both sit under one flap, check the diesel cap is still closed before you lift the bottle — then leave it on. - Finish once that tank fills or the bottle is empty; before that, tip gently using its built-in spout. - Only after that, start the car: close the cap, check again, and make sure the diesel cap was never opened. If at step two or three you find you have already poured into the diesel side, stop there. Don't go on to step five. ## Put AdBlue in your diesel tank around Crofts Bank already? Brief list, then. Top of it: your engine stays unstarted. The fuel pump runs on plenty of diesels as soon as your ignition goes on — and so leave it off. Topping up with diesel won't weaken it: rather than mixing, AdBlue drops to the bottom of the tank, right where the fuel is drawn from. At a forecourt — Texaco, Shell or another — the attendants will normally help roll the car away, when you ask. At home around Crofts Bank? Then the car remains where it is.

What liquid was put in, the quantity, and whether it ran: we ask because the answers decide the work and quote. Nobody sets off until you have heard the quote by phone. After that: draining, then a full flush of the whole system. With AdBlue that counts more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, and so it does not wash out on its own. Testing is at the end: before that, clean diesel is added, and your filter is flushed or changed as needed. The engine is fired up next and checked to confirm it runs correctly, all before our technicians head off. If your engine hasn't run, most jobs take about half an hour once we're there, using pumps that are safe on a working forecourt and quiet enough to use outside a house at night. Nothing in advance; you settle up that day. Afterwards, a VAT invoice and a report from the engineer are handed to you for your insurer. Many insurance policies include misfuelling cover, so it's worth checking yours while we are on the way. ## About Crofts Bank itself Crofts Bank is a locality situated on the riverside in Greater Manchester, with an elevation of around 24 metres.
