--- title: Wilberfoss: AdBlue in a Diesel Tank, Explained canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/wilberfoss-east-riding-of-yorkshire/ location: Wilberfoss county: East Riding of Yorkshire latitude: 53.948860 longitude: -0.892250 service: AdBlue in a Diesel Tank updated: 2026-10-06 --- # AdBlue in a Diesel Tank in Wilberfoss: How It Happens and How to Prevent It Leave the motor and ignition off then phone 0333 366 0103 first — the rest can wait when AdBlue is already in the diesel tank. In Wilberfoss, catching it before the motor turns usually leaves draining and a full flush on the spot. Nothing happened yet? Below, the page explains the reasons it takes place and the how to prevent it for good. ## Two fillers, two tanks: AdBlue in a diesel car Diesel goes to your engine — but many current diesels seen round Wilberfoss and Low Catton hold a second liquid too. Kept in a tank of its own, AdBlue is sprayed into your exhaust stream to clean it. Each tank has its own filler. Other cars put the AdBlue filler in the boot or under the bonnet; plenty more place both together under one flap. The diesel side is fuelled at the pump all the time. Seldom topped up, AdBlue normally comes from a bottle, tipped by someone who must stop and think what cap it needs. That gap is where the slip lives. ## How AdBlue in the diesel tank takes place in Wilberfoss It is seldom carelessness. Three things tend to line up. On a drive off Pear Tree Close before work, or in the car park at The Oddfellows Arms heading home: that's where the rushed top-up happens. What is the reason for the rush? As AdBlue gets low your car warns you, and if it is empty, limp mode kicks in. The old car's filler is where the hand reaches — yet a hire car, a new vehicle or a company car puts the fillers elsewhere. That's the second factor: a new vehicle. Lastly, the bottle goes in: a diesel filler or AdBlue one, it slides in just as easily, and after the pour begins, nothing halts it. The same few seconds decide it, in the middle of Wilberfoss or out in Newton upon Derwent. ## The AdBlue filler and the diesel filler: telling them apart Whether a Wilberfoss forecourt or a drive over in Elvington, spend a few seconds over these before anything is poured in. - Colour and marking: an AdBlue cap is commonly blue, or says "AdBlue", where a diesel cap usually doesn't. Go by the cap, not its position. - On many cars, the size tells: AdBlue has the smaller filler neck. - The flap. Look inside the fuel flap for a label. Many motors say there which fuel goes where. - In your boot or under the bonnet: that's where your filler sits if it is not by the diesel cap, and the handbook says which. - Whoever had it before knows. Ask as you pick up a rental or company car — from York's car park, say — not once the light comes on. ## How to top up without AdBlue in your diesel tank The day the light goes on, anywhere around East Riding of Yorkshire, use this routine. - Park then switch off. Not on a slope, not with the engine running, and not in a rush on the side of The Paddock. - Say "AdBlue" out loud as you unscrew the cap, after finding the AdBlue filler and read it. Silly, yes, but it does the trick. - The two under a single flap? Then make sure the lid on the diesel side is still shut ahead of raising the bottle. - Stop when your tank fills or the bottle runs dry; until then, pour gently through its own spout. - Only then, start the car: close the cap, check a second time, and make sure your diesel cap was never opened. Discover during the second or third step that AdBlue went into the diesel tank? That's where you stop. Never go on to step five. ## Put AdBlue in the diesel tank in Wilberfoss already? Do not start your engine: that is how the short order of things begins. On many diesels your ignition alone runs the fuel pump, so don't switch it on. Do not top up with diesel to dilute it: AdBlue does not mix with diesel, it sinks to the bottom of the tank, where the fuel is pulled from. On a forecourt — JET, Esso or another — the attendants will normally help push the car clear, when you ask. If you are on your own driveway in Wilberfoss, leave the car where it is. Stop as soon as it is safe then switch off, if the motor has already run. On the M62, under 15 miles from Wilberfoss, that means the next junction. A short hop across Wilberfoss is a smaller job than a run towards York, under 10 miles away, so tell us roughly how far it went. ## What occurs when our engineers arrive in Wilberfoss Outside Wilberfoss Church of England Primary School, close to Wilberfoss Community Centre or on your own drive: wherever your car has stopped, our engineers come to it. What fluid went in, the quantity, and if it ran: our engineers ask since those replies decide both work and price. On the phone call itself, you hear our price — before dispatch. The system is then cleaned thoroughly, after the tank is drained. Much more than with petrol, it matters here: crystals form, some metals are attacked, and none of that washes out unaided, no matter how long it sits. Filter flushed or, where needed, swapped; fresh diesel in; and then a test of your car. We do not go until it has been started and is running correctly. Using pumps safe on a busy forecourt and quiet enough for use outside a house at night, most jobs in which the engine has not run need roughly half an hour once our technicians are there. Nothing in advance; you settle up on the day. At the end, the VAT invoice and the report from the engineer go to you for your insurer. It's worth checking your policy as the van travels to you: misfuelling cover is included with many policies. ## About Wilberfoss itself Wilberfoss is a village situated on the banks of the River Derwent in the East Riding of Yorkshire, with a population of around 1381 residents.
