Pause reading for a moment when the diesel tank already holds AdBlue in it: ignition off, motor off, and ring 0333 366 0103. Around Scotland End, catching it before the engine runs usually leaves a drain and a thorough flush on the spot. Here in advance? Then what follows covers why it comes about and what to stop it happening at all. ## AdBlue in a diesel car, and its separate tank Many current diesels on the roads about Scotland End and East End carry two liquids, not one. Diesel goes to your engine. Stored in a tank of its own, AdBlue is fed into your exhaust gas to clean it. Each tank has its own filler. On a lot of vehicles the two sit side by side under the same flap; on others the AdBlue filler is in the boot or under the bonnet. The diesel side is fuelled at the petrol pump all the time. The AdBlue side is fuelled far less regularly, normally from a bottle, and normally by someone who has to stop and think where it goes. The slip lives in that gap. ## How AdBlue in your diesel tank happens around Scotland End It's hardly ever carelessness. Three things tend to line up. The warning comes first. As AdBlue runs low the car tells you, and if it runs out altogether, the vehicle drops into limp mode. So the top-up is done in a hurry: on a driveway off Clay Bank before work, or in the car park outside The Pear Tree on the way home. Then the vehicle is strange. A hire car, a new motor or a company car puts the fillers where your last one did not, and your hand reaches for the cap it would have used on the old one. A spout-topped bottle meets no resistance at a diesel filler no more than at an AdBlue one. So the pour, after started, keeps on. Hook Norton or the heart of Scotland End: it is the same few seconds in both. ## Which filler is for AdBlue, and which for diesel? Check these before pouring, on a forecourt in Scotland End or a driveway out in Ascott. Seconds, no more. - Read the cap instead of going by position: AdBlue caps are frequently blue or marked "AdBlue", and diesel caps normally aren't. - Check the size: the smaller filler neck is, on many vehicles, the AdBlue one. - Look inside your fuel flap: many motors have a label there saying which fuel goes where. - In your boot or under the bonnet: that is where your filler is if it's not by the diesel cap, and the handbook tells you which. - Ask the person who drove it last — before you leave, not when the light comes on — if you pick up a hire or company car from somewhere like the car park at Banbury. ## Topping up AdBlue without it reaching your diesel tank When the light goes on, wherever across Oxfordshire, follow this routine. - Park and switch off. Not on a slope, not with your motor running, and not in a rush on the side of Chipping Norton Road. - Say "AdBlue" out loud as you unscrew the cap, after finding the AdBlue filler and read it. Silly, yes, yet it does the trick. - The two under a single flap? Then make sure the cap on the diesel side stays closed before lifting the bottle. - Stop when that tank fills or the bottle runs dry; until then, tip gently using its built-in spout. - Only after that, start the vehicle: 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 your diesel side, stop there. Stage five stays out. ## Put AdBlue in the diesel tank around Scotland End already? Do not start the engine: that is how the short order of things begins. Keep your ignition off too, since on plenty of diesels it by itself runs the pump. Filling up with diesel won't weaken it: rather than mixing, AdBlue sinks to the bottom of the tank, just where the fuel is drawn from. Ask the staff to help roll the car clear of the pump if you are on a forecourt — the Shell, the Esso or somewhere else. On your own drive in Scotland End? So your car remains put. When your motor has been run by now, pull over somewhere safe then switch it off. Scotland End sits under 10 miles from the M40; there, use the next junction.

Which fluid got in, the amount, and whether it ran: our technicians ask since the replies decide the work and quote. Nobody heads out before you've had the price by phone. Draining your tank comes next, followed by a full flush of the fuel system. Unlike petrol, AdBlue leaves crystals and attacks certain fuel-system metals, and none of it clears away by itself. That is why it counts more. After the filter has been cleaned — or replaced, if required — fresh diesel is added, and finally the vehicle gets tested. After that we fire it up and confirm it runs correctly before we leave. If your motor has not run, most jobs take about half an hour once we're there, using pumps that are safe on a busy forecourt and quiet enough to use outside a house at night. No money upfront; you settle up that day. Afterwards, the VAT invoice and a report from the engineer go to you for the insurer. It is worth looking at your policy while we travel to you: misfuelling cover comes with many policies. ## About Scotland End and where it is Scotland End is a suburban area in Oxfordshire, situated inland at an elevation of 156 metres, and is located approximately 19.6 miles from Oxford.
