If AdBlue is already in your diesel tank, stop reading for a moment: leave the engine and the ignition off and call 0333 366 0103. In Winthorpe, finding it before your engine runs usually leaves draining and a full flush on the spot. If you're reading before it has happened, the rest of this page is about why it occurs and how to make sure it does not. ## Two fillers, two tanks: AdBlue in a diesel car Many modern diesels on the roads about Winthorpe and Holme carry two liquids, not one. Diesel goes to your motor. AdBlue goes to your exhaust, where it is sprayed into the gas to fresh it, and it lives in a tank of its own. Each tank has a filler of its own. On a lot of cars the two sit side by side under the same flap; on others the AdBlue filler is in your boot or under the bonnet. The diesel side is fuelled at the pump all the time. The AdBlue side is filled far less regularly, 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 AdBlue in the diesel tank takes place around Winthorpe Carelessness rarely causes it. What does is three things lining up at once. The warning comes first. As AdBlue runs low your car tells you, and if it runs out completely, your vehicle drops into limp mode. So the top-up is done in a hurry: on a driveway off Holme Lane before work, or in the car park outside The Lord Nelson on the way home. New-to-you vehicles come next, as well. Hire cars, new vehicles and company vehicles put their fillers in new places, and habit reaches for the cap it 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, so nothing stops the tip after it has started. Whether it takes place in Langford or the middle of Winthorpe, it is the same few seconds. ## The AdBlue filler and the diesel filler: telling them apart Be it a Winthorpe forecourt or a drive over in Beacon Hill, spend a couple of seconds over these before anything goes in. - Blue and lettering: an AdBlue cap is frequently blue, or says "AdBlue", where a diesel cap usually doesn't. Trust the cap, not its position. - Plenty of vehicles fit AdBlue the smaller neck of the two. - The flap. Look inside your fuel flap for a label. Plenty of vehicles say there which fuel goes where. - The handbook. If the filler isn't by the diesel cap, it's in your boot or under the bonnet, and the handbook says which. - Check with the person who drove it last — before you leave, not when the light comes on — when you collect a hire or company car from somewhere like the car park outside Newark Northgate. ## Keeping AdBlue out of the diesel tank when you top up A routine for the day the light comes on, wherever around Nottinghamshire that is. - Turn off once parked — level ground, motor stopped, and never rushed beside Gainsborough Road at the roadside. - Silly as it sounds, speaking "AdBlue" out loud as you unscrew the cap does the trick — after you have located your filler and read the cap. - The diesel cap stays on. When both share a flap, make sure it is closed before the bottle comes up. - Finish once your tank is topped up or the bottle runs dry; before that, pour gently through its built-in spout. - Close the cap and check a second time. Make sure the diesel cap was never opened. Only then start the vehicle. If at stage two or three you find you have already poured into the diesel side, stop there. Skip step five entirely. ## Already put AdBlue in the diesel tank in Winthorpe? Don't start your engine: that is where the short order of things starts. On many diesels the ignition alone runs the fuel pump, and so don't switch the vehicle on. Topping up with diesel will not weaken it: rather than mixing, AdBlue sinks to the base of your tank, just where the fuel is taken from. Ask the staff to help roll the vehicle away from the pump if you are on a forecourt — the Esso, the Shell or anywhere else. On your own drive around Winthorpe? Then the vehicle remains where it is. Stop as soon as it is safe then switch off, if your engine has already run. Leave the M1 — under 25 miles out of Winthorpe — at the next exit. Tell us about how far it went: a run towards Lincoln, under 15 miles away, is a bigger job than a short hop across Winthorpe. ## When our engineers turn up around Winthorpe, what happens? The van comes to your car wherever it stopped — your own drive, near Winthorpe Village Hall, or by Winthorpe Primary School. Our technicians ask what got in, roughly how much, and whether it has run, because those answers determine this work and the quote. The price comes on the call, before any van leaves. The system is then purged thoroughly, after that tank is emptied. AdBlue crystallises and is corrosive to some of the metals in a fuel system, so it does not wash out on its own — which is why the flush counts more here than with petrol. A test comes last: before that, clean diesel is added, and the filter is flushed or replaced if necessary. The engine is fired up next and checked to make sure it runs correctly, all before our technicians leave. With pumps safe on a busy forecourt and quiet enough to use outside a house at night, most jobs where the motor hasn't run take about half an hour once our technicians arrive. No money in advance; you settle up that day. Afterwards, the VAT invoice and the report from the engineer go to you for the insurer. It's worth looking at your insurance while we travel to you: misfuelling cover comes with plenty of policies. ## About Winthorpe itself Winthorpe is a small village in Nottinghamshire, situated on the banks of the River Trent at an elevation of around 20 metres.
