--- title: Explained: AdBlue in a Diesel Tank East Gillibrands canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/east-gillibrands-lancashire/ location: East Gillibrands county: Lancashire latitude: 53.542520 longitude: -2.784950 service: AdBlue in a Diesel Tank updated: 2026-10-02 --- # Why It Happens and How to Prevent It: AdBlue in a Diesel Tank in East Gillibrands AdBlue already in your diesel tank? Then set this page aside for now, leave your ignition and motor off, then phone 0333 366 0103. A drain plus a thorough flush, carried out right where your vehicle stands in East Gillibrands, is usually all it needs when caught before the motor runs. If you're reading before it has happened, the rest of this page is about why it occurs and how to make sure it does not. ## Two fillers, two tanks: AdBlue in a diesel car Diesel feeds the motor — yet many modern diesels driven about East Gillibrands and Town Centre carry a second fluid too. AdBlue goes to the exhaust, where it is sprayed into the gas to fresh it, and it lives in a tank of its own. Different tanks, different fillers. Under one flap, side by side: that is the arrangement on many motors. On others, AdBlue's filler sits under the bonnet or in the boot instead. Diesel goes in at every filling station call-out, week in, week out. The AdBlue side is filled far less regularly, usually from a bottle, and normally by somebody who has to stop and think where it goes. The mistake lives in that gap. ## How AdBlue in your diesel tank happens in East Gillibrands Seldom is it carelessness: normally three things line up. On a drive off Glebe Road before work, or in the car park at Derby Arms heading home: that is where the hurried top-up happens. What is the reason for the rush? As AdBlue gets low your car tells you, and once it is empty, limp mode follows. Then, the hand goes for the cap it would have used on the old car — since a rental car, a new motor or a company car places the fillers somewhere your last one didn't. A spout-topped bottle finds no obstacle at a diesel filler no more than at an AdBlue one. And so the pour, once begun, carries on. Whether it takes place in White Moss or the middle of East Gillibrands, it is the same few seconds. ## Telling the AdBlue filler from the diesel filler A few seconds is all these take — so check them before you pour anything, on a driveway in Digmoor or a forecourt in East Gillibrands. - The cap. The AdBlue cap is regularly blue, or marked "AdBlue". Your diesel cap normally isn't. Read it instead of going by position. - Plenty of motors fit AdBlue the smaller filler of the two. - The flap. Look inside the fuel flap for a label. Many cars say there which fuel goes where. - The handbook shows where it lives when the filler isn't next to the diesel cap: the boot, or under the bonnet. - Whoever had it before knows. Ask when you collect a rental or fleet car — from Rainford's car park, perhaps — rather than once the light appears. ## Topping up AdBlue without it reaching the diesel tank The day the light comes on, anywhere around Lancashire, follow this routine. - Park and switch off. Not on a slope, not with your engine running, and not in a rush on the side of Garnett Place. - Say "AdBlue" out loud as you unscrew the cap, once you find the AdBlue filler and reading it. Silly, perhaps, yet it works. - The two behind a single flap? So confirm the lid on the diesel side is still shut before raising the bottle. - Pour slowly, using the bottle's own spout. Stop when it is full or when the bottle is empty. - Only after that, start the car: close the cap, check a second time, and make sure the diesel cap was never opened. If at stage two or three you find you have already poured into your diesel side, stop there. Do not go on to stage five. ## Put AdBlue in your diesel tank in East Gillibrands already? Don't start your motor: that's how the short order of things starts. The fuel pump runs on many diesels as soon as your ignition is switched on — and so leave it off. Don't top up with diesel to thin it: AdBlue doesn't mix with diesel, it sinks to the bottom of that tank, where the fuel is drawn from. On a forecourt — Shell, Asda or another — the staff will usually help roll the car away, if you ask. If you're on your own drive around East Gillibrands, leave the vehicle where it sits. If the motor has already run, stop as soon as it is safe and switch off. The next junction means where to leave if you're on the M58, under a mile from East Gillibrands. A short hop across East Gillibrands is a smaller job than a run towards Liverpool, under 15 miles away, and so tell us about how far it went. ## Our arrival in East Gillibrands, and what occurs next Anywhere the car has stopped, whether outside St Edmund's Catholic Primary School, near J4 or at home, our van travels to it. We ask what went in, about how much, and if it's run, since those replies determine this work and our quote. The price comes over the phone, before any van leaves. Next: draining, then a thorough flush of the entire system. With AdBlue that matters more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, so it does not wash out on its own. A test comes last: before that, fresh diesel is added, and the fuel filter is flushed or replaced as needed. After that we fire it up and make sure it runs smoothly before we leave. With pumps safe on a busy forecourt and quiet enough to use outside a house at night, most jobs where the engine hasn't run need about half an hour once our engineers arrive. The insurer usually wants the engineer's report and the VAT invoice, and you get both once the job is done. Payment is on the day, with no deposit. It is worth looking at your insurance while we travel to you: misfuelling cover comes with plenty of policies. ## About East Gillibrands itself East Gillibrands is a small suburban area in Lancashire, situated near the river and close to the towns of Skelmersdale and Ormskirk.
