--- title: AdBlue in a Diesel Tank Dodworth Green: Explained canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/dodworth-green-south-yorkshire/ location: Dodworth Green county: South Yorkshire latitude: 53.539990 longitude: -1.530940 service: AdBlue in a Diesel Tank updated: 2026-10-04 --- # Dodworth Green: How Does AdBlue End Up in a Diesel Tank, and How Do You Prevent It? Pause here for a moment if your diesel tank already holds AdBlue in it: ignition off, motor off, and phone 0333 366 0103. A drain and a thorough flush, carried out just where the vehicle sits in Dodworth Green, is usually all it takes when found before your engine runs. If you are reading before it has happened, the remainder of this page is about why it occurs and how to make sure it does not. ## AdBlue in a diesel motor, and its separate tank Plenty of modern diesels in Keresforth Hill, as well as Dodworth Green, run on two liquids; your motor gets only the diesel. AdBlue's own tank keeps it, and from there it goes to the exhaust, where spraying treats the gas. Each tank has its own filler. Other motors put the AdBlue filler in your boot or under the bonnet; plenty of others have both together under one flap. The diesel side is fuelled at the pump all the time. The AdBlue side is topped up far less regularly, usually from a bottle, and normally by somebody who has to stop and think where it goes. The mistake grows in the gap between them. ## How does AdBlue in the diesel tank occur around Dodworth Green? It is hardly ever carelessness. Three things tend to line up. To start with, the warning. Low AdBlue brings a message from the vehicle, and letting it run dry means limp mode — so a hurried top-up, perhaps before work off Green Road, perhaps outside Dodworth Central Social Club on the way home that evening. Then your car is strange. A hire car, a new motor or a company car puts the fillers where your last one didn't, and the hand gets to for the cap it would have used on the old one. Third, the bottle goes in: diesel filler or AdBlue one, it slides in just as easily, and once the pour begins, no part halts it. The same few seconds settle it, in the middle of Dodworth Green or out in Dodworth. ## The AdBlue filler and the diesel filler: telling them apart Look at these before pouring, at a forecourt in Dodworth Green or a drive over in Gilroyd. A few seconds, that's all. - Where it sits can mislead; the cap does not. AdBlue caps tend to be blue or bear the word "AdBlue" — diesel caps normally don't. - Look at the size: the smaller filler neck is, on many cars, the AdBlue one. - Open the flap and check for a label — plenty of motors mark which goes in which inlet just there. - The handbook. If the filler isn't by the diesel cap, it is in the boot or under the bonnet, and the handbook says which. - Whoever had it before knows. Ask as you pick up a rental or company car — from Dodworth's car park, say — rather than when the light comes on. ## How to top up without AdBlue in the diesel tank Wherever in South Yorkshire the light comes on, here is a routine for the day. - Stop on level, motor off, with time in hand — never rushing on the side of Ratten Row. - Daft as it sounds, speaking "AdBlue" out loud as you unscrew the cap works — after you have found your filler and read it. - The two behind one flap? So make sure the cap on the diesel side stays closed before lifting the bottle. - Pour slowly, using the bottle's own spout. Stop when it's full or when the bottle is empty. - Close the cap, then look once more — confirm your diesel filler remained closed the whole time. After that, start the car. Find at the second or third stage that AdBlue went in the wrong tank? That is where you stop. Don't go on to step five. ## Put AdBlue in your diesel tank in Dodworth Green already? Brief list, then. Top of it: your engine stays unstarted. The fuel pump starts on plenty of diesels as soon as your ignition is switched on — so leave it off. Don't top up with diesel to thin it: AdBlue does not mix with diesel, it sinks to the bottom of your tank, where your fuel is drawn from. On a forecourt — Asda, Jet or another — the attendants will normally help push the car away, if you ask. Leave it where it is if you are on your own driveway in Dodworth Green. When your motor has run already, pull over somewhere safe then turn the vehicle off. Come off the M1 — under a mile out of Dodworth Green — at the first junction. Distance matters — a quick hop across Dodworth Green is a smaller job than driving under 15 miles to Wakefield — so say roughly how far it went. ## Our arrival in Dodworth Green, and what occurs next Outside Dodworth St John the Baptist CofE Primary Academy, near St John the Baptist or on your own drive: wherever the car has stopped, our technicians come to it. Our engineers ask what was put in, roughly how much, and if it's run, since those answers decide this work and our quote. Nobody sets off until you've had our price over the phone. Draining that tank comes next, then a full flush of your system. Unlike petrol, AdBlue leaves crystals and eats at some fuel-system metals, and neither clears out unaided. That is why it counts more. Once the fuel filter is flushed — or replaced, where required — fresh diesel is added, and then your vehicle gets tested. We do not go until it has been fired up and is running smoothly. If your motor has not run, the majority of jobs take about half an hour once we are there, using pumps that are fine on a busy forecourt and quiet enough to use outside a house after dark. The insurer will ask for the engineer's report and the VAT invoice, and both are yours once this job is done. Payment is on the day, with no money upfront. Wrong-fuel cover is included in many insurance policies — and so make use of the wait to check yours. ## About Dodworth Green itself Dodworth Green is a suburban area in South Yorkshire, situated near the town of Dodworth and close to the city of Wakefield.
