--- title: AdBlue in a Diesel Tank Clopton: Explained canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/clopton-warwickshire/ location: Clopton county: Warwickshire latitude: 52.203380 longitude: -1.709100 service: AdBlue in a Diesel Tank updated: 2026-10-05 --- # AdBlue in a Diesel Tank in Clopton: Why It Happens and How to Stop It AdBlue already in the diesel tank? In that case put this page aside for now, keep your ignition and engine off, then ring 0333 366 0103. Caught before the engine runs, it's normally a drain and a thorough flush, done where your car is in Clopton. The rest of this page covers why it happens and how to ensure it does not — handy if you're reading ahead of time. ## Why does AdBlue in a diesel car need its own filler? Plenty of newer diesels on the roads about Clopton and Old Town carry two liquids, not one. Diesel goes to the motor. Kept in a tank of its own, AdBlue is fed into the exhaust gas and cleans it. Separate tanks, different fillers. 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. At the petrol pump, your diesel side is topped up constantly. Much less regularly, the AdBlue side gets filled — normally from a bottle, by a person thinking about where it goes. The mistake grows in the gap between them. ## How AdBlue in the diesel tank happens in Clopton It's seldom carelessness. Three things tend to line up. On a driveway off Justins Avenue before work, or in the car park at Yard of Ale heading home: that's where the rushed top-up happens. Why the rush? As AdBlue gets low the car tells you, and once it is empty, limp mode follows. Next, the hand goes for the cap it knew on the old car — because a hire car, a new motor or a company car puts the fillers somewhere your last one did not. No part stops the tip after it has started, because a bottle with a spout goes into a diesel filler as easily as an AdBlue one. The bottle fits. It takes a few seconds, whether in Stratford-upon-Avon or right in the heart of Clopton. ## The AdBlue filler and your diesel filler: telling them apart A few seconds is all these take — so check them before you pour anything, on a drive in Ingon or a forecourt around Clopton. - Where it sits misleads; the cap does not. AdBlue ones tend to be blue or bear the word "AdBlue" — diesel ones usually do not. - The size. On plenty of cars the AdBlue filler neck is the smaller of the two. - A label inside the fuel flap frequently says which fuel goes where, on plenty of vehicles. Check for it. - In your boot or under the bonnet: that's where your filler sits if it's not by your diesel cap, and the handbook tells you which. - Check with 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 outside Stratford-upon-Avon. ## Topping up AdBlue without it reaching your diesel tank Anywhere in Warwickshire the light comes on, here is a routine for the day. - Stop on level, engine off, with time to spare — never hurried on the side of Clopton Road. - Find the AdBlue filler, check the cap, and say the word "AdBlue" aloud as you unscrew it. It seems daft. It works. - The diesel cap remains on. When both share a flap, make sure it is shut before lifting the bottle. - Gently does it, through the bottle's own spout, till it's full or the bottle is empty. - Before you start the car, shut the cap and check a second time that your diesel cap was never opened off. Stop there if you find, at stage two or three, that you've already poured into your diesel side. Leave out stage five entirely. ## Put AdBlue in your diesel tank around Clopton already? Do not start your engine: that is how the short order of things begins. The fuel pump runs on plenty of diesels as soon as the ignition goes on — and so leave it off. Do not top up with diesel to dilute it: AdBlue does not mix with diesel, it sinks to the bottom of the tank, where your fuel is pulled from. If you are on a forecourt, whether it is the Tesco or the Morrisons, ask the attendants to help push your car away from the pump. Your own driveway around Clopton is where it should stay. Already run? Pull over when it's safe, then turn off. Leave the M40 — under 10 miles out of Clopton — at the first junction. A short hop across Clopton is a smaller job than a run towards Coventry, under 25 miles away, so tell us about how far it went. ## What takes place when our engineers arrive around Clopton Outside Thomas Jolyffe Primary School, close to TK Maxx or on your own drive: wherever the vehicle has stopped, our engineers come to it. We ask what was put in, about how much, and if it has run, since the replies determine the work and the price. The quote comes over the phone, ahead of any van leaving. Then the tank is drained and the fuel system flushed thoroughly. More than with petrol, it counts here: the crystals form, some metals are attacked, and none of it clears away on its own, no matter how long it is left. Testing is at the end: before that, fresh diesel goes in, and your filter is flushed or replaced as needed. Before we go, our engineers start it and make sure that it is running correctly. If the motor hasn't run, most jobs take about half an hour once we are there, using pumps that are safe on a busy forecourt and quiet enough to use outside a house at night. Payment happens on the day, not upfront, and you are given the documents your insurer wants: an engineer's report and a VAT invoice. It is worth looking at your insurance as the van travels to you: misfuelling cover is included with many policies. ## About Clopton and where it is Clopton is a suburban area in Warwickshire, situated on the riverside at an elevation of around 45 metres.
