--- title: AdBlue in a Diesel Tank Adel: Explained canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/adel-west-yorkshire/ location: Adel county: West Yorkshire latitude: 53.853880 longitude: -1.590210 service: AdBlue in a Diesel Tank updated: 2026-10-03 --- # AdBlue in a Diesel Tank in Adel: How It Happens and How to Prevent It Stop here for a moment when your diesel tank already has AdBlue in it: ignition off, motor off, then call 0333 366 0103. Around Adel, catching it before your engine runs usually means 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 doesn't. ## AdBlue in a diesel vehicle, and its separate tank Diesel goes to your motor — but many newer diesels driven about Adel and Low Farm carry another fluid as well. Kept in a tank of its own, AdBlue is fed into the exhaust stream to clean it. Each tank has its own filler. Under one flap, next to each other: that is the layout on many cars. Elsewhere, AdBlue's filler is under the bonnet or in the boot instead. At the pump, the diesel side gets filled all the time. Rarely filled, AdBlue usually comes out of a bottle, poured by a driver who must stop and think what cap it needs. It's in that gap that the mistake lives. ## How AdBlue in the diesel tank happens in Adel Rarely is it carelessness: normally three things line up. To start with, the warning. Low AdBlue brings a message from the car, and letting it run out leads to limp mode — hence a rushed top-up, perhaps before work off Adel Lane, perhaps at Adel War Memorial Association on the way home that evening. Then your car is unfamiliar. A hire car, a new car or a company car puts the fillers where your last one didn't, and your hand reaches 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, so nothing stops the tip once it has started. The same few seconds settle it, in the middle of Adel or out in Adel East Moor. ## How to tell the AdBlue filler from the diesel one Be it a Adel forecourt or a drive out in Lawnswood, spend a couple of seconds on these before anything is poured in. - Colour and marking: an AdBlue cap is regularly blue, or says "AdBlue", where a diesel cap normally doesn't. Trust the cap, not where it sits. - Check the size: the smaller filler neck is, on many cars, the AdBlue one. - Look inside the fuel flap: many cars have a label there showing which fuel goes where. - The handbook says which it lives if your filler isn't next to your diesel cap: the boot, or under the bonnet. - Whoever had it before will know. Ask when you collect a rental or fleet car — from Horsforth's car park, perhaps — not when the light appears. ## How to top up without AdBlue in the diesel tank On the day the warning comes on — wherever it is around West Yorkshire — a simple routine to use. - Turn off once parked — level ground, engine off, and not in a rush by Church Lane on the verge. - Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds daft and it does the trick. - Both under one flap? So make sure the lid on your diesel filler is still shut ahead of raising the bottle. - Finish when the tank fills or the bottle is empty; until then, pour gently using its built-in spout. - Before starting your car, close the cap and check a second time that the diesel cap was never came off. Find at the second or third stage that the bottle went in the wrong tank? That is where you stop. Never go on to stage five. ## Already put AdBlue in your diesel tank in Adel? Do not start the engine: that is how the short order of things starts. Do not switch the ignition on; on plenty of diesels that alone runs the fuel pump. AdBlue does not mix with diesel — it sinks to the bottom of the tank, where your fuel is sucked from — so do not top up with diesel to thin it. Ask the staff to help push the vehicle clear of the pump if you're at a forecourt — the BP, the Esso or anywhere else. Leave it where it is if you are on your own drive around Adel. If your motor has already run, stop as soon as it is safe and switch off. Adel lies under 5 miles from the A58(M); there, use the first junction. Tell us about how far it went: a run towards Leeds, under 5 miles away, is a bigger job than a short hop across Adel. ## When we arrive around Adel, what occurs? Our technicians come to your car wherever it has stopped, whether that is outside Adel St John the Baptist Church of England Primary School, near Adel Sports and Social Club or on your own drive. The replies decide this work and the price, so our technicians ask what went in, roughly how much, and whether it has run. Nobody sets off before you have heard the price by phone. Then that tank is drained and the system cleaned thoroughly. Not like petrol, AdBlue forms crystals and attacks certain fuel-system metals, and neither washes out unaided. Hence it counts more. Once your filter has been cleaned — or replaced, where needed — fresh diesel goes in, and finally the vehicle gets tested. We don't go until it has been started and is running properly. Most jobs are done in about half an hour once our engineers arrive, as long as your engine hasn't run — and the pumps our engineers use are safe on a live forecourt and quiet after dark outside a house. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Plenty of insurance policies include misfuelling cover, and so it is worth checking yours while we are on the way. ## About Adel, for a moment Adel is a suburban area in West Yorkshire, situated approximately 4 miles north-west of Leeds city centre.
