--- title: Croft: AdBlue in a Diesel Tank, Explained canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/croft-lancashire/ location: Croft county: Lancashire latitude: 53.919910 longitude: -2.191320 service: AdBlue in a Diesel Tank updated: 2026-10-07 --- # Why It Occurs and How to Avoid It: AdBlue in a Diesel Tank in Croft If AdBlue is already in your diesel tank, stop reading for a moment: leave the motor and your ignition off and ring 0333 366 0103. Caught before your engine runs, it is usually a drain and a thorough flush, done where the car is around Croft. Not happened yet? Further down, the rest of the page covers the why it takes place and the how to prevent it altogether. ## Two fillers, two tanks: AdBlue in a diesel car Not one fluid but two: that is how plenty of newer diesels around Croft and Town Head run, with diesel for the motor. The exhaust, not your engine, is where AdBlue goes: sprayed into the fumes to clean it, from a separate tank. There is a filler for each tank. Under one flap, side by side: that's the layout on many motors. Elsewhere, AdBlue's filler is beneath the bonnet or in your boot instead. Diesel gets filled on each filling station visit, again and again. Much less frequently, the AdBlue side gets topped up — mostly from a bottle, by someone thinking about where it goes. That gap is where the mistake lives. ## How does AdBlue in your diesel tank take place around Croft? It's rarely carelessness. Three things tend to line up. The warning comes first. As AdBlue runs low your car tells you, and if it runs out altogether, the car goes into limp mode. So the top-up is done in a hurry: on a drive off Gisburn Road before work, or in the car park outside The Barlick Tap Ale House on the way home. Next, the hand goes for the cap it knew on the old vehicle — since a rental car, a new car or a company car puts the fillers somewhere your last one did not. Lastly, the bottle fits: diesel filler or AdBlue filler, it goes in as readily, and after the tip begins, nothing stops it. Barnoldswick or the heart of Croft: it takes the same few seconds in both. ## The AdBlue filler and the diesel filler: telling them apart Look at these before pouring, on a forecourt in Croft or a driveway over in Coates. A few seconds, no more. - The cap. The AdBlue cap is regularly blue, or marked "AdBlue". The diesel cap usually isn't. Read it rather than going by position. - On many vehicles, the size tells: AdBlue has the smaller filler neck. - Look inside your fuel flap: many cars have a label there saying which fuel goes where. - Can't find it beside the diesel filler? In that case look below the bonnet or inside your boot — the handbook says which. - The previous driver will know. Check when you pick up a rental or fleet car — at Colne's car park, say — rather than once the warning appears. ## AdBlue top-ups that never reach the diesel tank Anywhere around Lancashire the light comes on, this is a routine for that day. - Switch off after you park — flat ground, motor stopped, and never in a rush by Denton Street on the verge. - Daft as it sounds, saying "AdBlue" out loud as you unscrew the cap works — once you have located your filler and read the cap. - Both behind a single flap? Then confirm the cap on your diesel filler is still closed before lifting the bottle. - Slowly does it, through the bottle's own spout, until it is full or the bottle runs out. - Before you start your car, close the cap and look a second time that the diesel cap was never opened off. Find at the second or third step that AdBlue went in the diesel filler? That is where you stop. Step five is off limits. ## Put AdBlue in the diesel tank in Croft already? Short order, then. First: your engine stays unstarted. The fuel pump runs on plenty of diesels the moment your ignition goes on — and so keep it off. Topping up with diesel won't weaken it: rather than mixing, AdBlue sinks to the bottom of your tank, right where the fuel is taken from. If you're on a forecourt, whether it is the Texaco or the Shell, ask the staff to help roll the car away from the pump. If you're on your own driveway around Croft, leave the vehicle where it sits. Already started? Pull over when it's safe, then switch off. Come off the M65 — under 5 miles out of Croft — at the next junction. Roughly how far did it go? Crossing Croft is smaller a job than a run of under 25 miles towards Bradford, and so tell us. ## Our arrival in Croft, and what takes place next Anywhere the vehicle came to rest, whether outside Gisburn Road Community Primary School, near St Joseph's Church or on your own drive, our van travels to it. Our engineers ask what got in, roughly how much, and whether it has run, because those answers determine this work and the price. Nobody sets off before you've heard our quote by phone. Next: a drain, then a full flush of the entire system. Not like petrol, AdBlue forms crystals and attacks certain fuel-system metals, and neither clears away unaided. Hence it counts more. The filter flushed or, if it must be, swapped; clean diesel in; then a check of the car. We don't leave until it has been fired up and is running correctly. With pumps safe on a working forecourt and quiet enough to use outside a house at night, most jobs in which your motor has not run need roughly half an hour once we are there. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Misfuelling cover is included in many insurance policies — so use the wait to look at yours. ## About Croft itself Croft is a suburban area in Lancashire, situated on the riverside with a mix of terraced housing.
