--- title: AdBlue in a Diesel Tank Wistow? Read This canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/wistow-north-yorkshire/ location: Wistow county: North Yorkshire latitude: 53.814050 longitude: -1.100360 service: AdBlue in a Diesel Tank updated: 2026-10-24 --- # Why It Occurs and How to Prevent It: AdBlue in a Diesel Tank in Wistow If AdBlue is already in your diesel tank, stop reading for a moment: leave your motor and the ignition off and phone 0333 366 0103. Usually, when the motor hasn't turned, it is drained and fully flushed where the vehicle sits in Wistow. If you're reading before it has happened, the remainder of this page is about why it takes place and how to make sure it does not. ## Two fillers, two tanks: AdBlue in a diesel car No single fluid but two: that is how many modern diesels near Wistow and Thorpe Wood run, with diesel feeding the engine. AdBlue's own tank holds it, and from there it goes to the exhaust, where a spray treats the fumes. Each tank has its own filler. Some cars put the AdBlue filler in your boot or under the bonnet; a lot more have the two together under one flap. Diesel gets filled on each filling station call-out, again and again. A driver who has to stop and think where it goes usually tops up the AdBlue side, from a bottle, and much less often. The mistake grows in the gap between the two. ## How does AdBlue in the diesel tank happen in Wistow? Seldom is it carelessness: usually three things 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 Prospect Place before work, or in the car park outside Black Swan 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 didn't, and the hand reaches for the cap it would have used on the old one. Lastly, the bottle fits: diesel filler or AdBlue filler, it goes in as readily, and once the tip starts, nothing halts it. Whether it occurs in Dawker Hill or the middle of Wistow, it's the same few seconds. ## How to tell the AdBlue filler from the diesel one A couple of seconds is all the checks take — so check them before you pour anything, on a driveway in Riccall or a forecourt in Wistow. - Where it sits can mislead; the cap doesn't. AdBlue caps are often blue or carry the word "AdBlue" — diesel caps usually don't. - Plenty of vehicles give AdBlue the smaller neck of the two. - A label inside your fuel flap often shows which fuel goes where, on many vehicles. Look for it. - In your boot or under the bonnet: that is where your filler sits if it's not by your diesel cap, and the handbook tells you which. - Picking up a hire or company car, say at the car park outside Selby? Check with the person who drove the car last before leaving, rather than once the light comes on. ## Keeping AdBlue out of your diesel tank when you top up On the day the light appears — wherever you are in North Yorkshire — a routine to follow. - Park and switch off. Not on a slope, not with your engine running, and not in a rush on the side of Lordship Lane. - Say "AdBlue" out loud as you unscrew the cap, once finding the AdBlue filler and reading it. Silly, yes, but it does the trick. - Both under a single flap? Then make sure the lid on the diesel side stays closed before lifting the bottle. - Using the bottle's own spout, tip slowly — and stop when it is full or the bottle is empty. - Before starting the car, close the cap and look a second time that the diesel cap never came off. If at step two or three you find you have already poured into your diesel side, stop there. Do not go on to step five. ## Already put AdBlue in your diesel tank around Wistow? Don't start your motor: that is how the short order of things starts. Don't switch the ignition on; on many diesels that alone runs the fuel pump. Filling up with diesel will not thin it: instead, AdBlue drops to the bottom of the tank, just where fuel is drawn from. If you are on a forecourt, whether it is the BP or the JET, ask the staff to help roll the vehicle clear of the pump. If you are on your own drive in Wistow, leave the car where it is. Stop as soon as it is safe and switch off, if the motor has already run. On the A1(M), under 10 miles from Wistow, that means the next junction. Tell us roughly how far it went: a run towards York, under 15 miles away, is a bigger job than a short hop across Wistow. ## Our arrival around Wistow, and what takes place next We come to the car wherever it has stopped, whether that is outside Wistow Parochial Church of England Voluntary Controlled Primary School, near All Saints or on your own driveway. The answers decide this work and the quote, and so our engineers ask what went in, about how much, and whether it's run. No one sets off until you have had our quote by phone. Next: draining, then a thorough flush of the entire 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. After the filter has been flushed — or replaced, if needed — clean diesel goes in, and then your car gets tested. We don't leave until it has been started and is running correctly. Using pumps fine on a busy forecourt and quiet enough for use outside a house at night, most jobs in which the engine hasn't run take about half an hour once our engineers arrive. Payment happens on the day, not upfront, and you are given the paperwork an insurer asks for: an engineer's report and a VAT invoice. Misfuelling cover is included in plenty of insurance policies — so use the wait to look at yours. ## About Wistow itself Wistow is a small village in North Yorkshire, situated near the city of York and close to the nearby places of Dawker Hill, Kelfield, and Cawood.
