--- title: AdBlue in a Diesel Tank Worthington? Read This canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/worthington-leicestershire/ location: Worthington county: Leicestershire latitude: 52.781790 longitude: -1.396150 service: AdBlue in a Diesel Tank updated: 2026-10-18 --- # How It Happens and How to Prevent It: AdBlue in a Diesel Tank in Worthington If AdBlue is already in your diesel tank, stop reading for a moment: leave your motor and the ignition off then ring 0333 366 0103. Caught before your motor runs, it is usually a drain and a thorough flush, done where the vehicle is around Worthington. Reading before the event? Then what follows explains why it comes about and how to prevent it ever happening. ## Why does AdBlue in a diesel car need its own filler? Diesel feeds your motor — yet plenty of current diesels driven around Worthington and Breedon on the Hill hold another liquid too. AdBlue's own tank holds it, and from there it goes to the exhaust, and there spraying cleans the gas. Separate tanks, different fillers. Under one flap, next to each other: that's the layout on a lot of motors. On others, AdBlue's filler sits beneath the bonnet or in your boot instead. At the pump, your diesel side is topped up all the time. Seldom filled, AdBlue normally goes in from a bottle, tipped by a driver who must stop and think which cap to use. That gap is where the slip lives. ## How does AdBlue in your diesel tank happen around Worthington? Rarely is it carelessness: normally three things line up. On a drive off St. Matthew's Avenue before work, or in the car park at The Malt Shovel on the way home: that is where the hurried top-up happens. Why the rush? As AdBlue gets low your car warns you, and if it's gone, limp mode kicks in. The old car's cap is where your hand reaches — but a hire car, a new car or a company car puts the fillers elsewhere. That's a second thing: a new motor. A spout-topped bottle meets no resistance at a diesel filler no more than at an AdBlue one. And so the tip, once started, carries on. Whether it happens in Newbold or the middle of Worthington, it's the same few seconds. ## How to tell the AdBlue filler from the diesel one Be it a Worthington forecourt or a driveway over in Gelsmoor, take a couple of seconds over these before anything goes in. - Where it sits misleads; the cap doesn't. AdBlue caps tend to be blue or bear the name "AdBlue" — diesel ones usually don't. - On many cars, size tells: AdBlue has the smaller filler neck. - A label inside your fuel flap frequently shows which fuel goes where, on many vehicles. Look for it. - In your boot or under the bonnet: that is where the filler is if it is not by the diesel cap, and the handbook tells you which. - The previous driver will know. Ask when you pick up a hire car or company car — from East Midlands Parkway's car park, perhaps — not when the warning comes on. ## Keeping AdBlue out of your diesel tank when you top up A routine for the day the light comes on, wherever around Leicestershire that is. - Not in a rush on the side of Main Street, not on a slope, not with your engine running: park and switch off first. - Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds silly and it does the trick. - If both sit under one flap, check your diesel cap is still closed before you lift the bottle — then leave the vehicle on. - Finish once the tank fills or the bottle runs dry; until then, tip slowly using its own spout. - Only then, start the vehicle: close the cap, check once more, and make sure your diesel cap was never opened. Find at step two or three that it has already gone into your diesel side? So stop just there. Leave out step five entirely. ## Put AdBlue in the diesel tank in Worthington already? What follows is a short order of things, starting with not starting the motor. On many diesels your ignition alone runs the fuel pump, so do not switch the vehicle on. AdBlue doesn't mix with diesel — it sinks to the bottom of your tank, where your fuel is pulled from — so do not top up with diesel to thin it. The attendants at Shell, Esso or another forecourt will usually help pushing the car clear if you ask. Your own driveway in Worthington is where it should stay. Already run? Stop once it is sensible, then turn off. Leave the M1 — under 5 miles out of Worthington — at the first exit. Distance counts — a quick hop across Worthington is a smaller job than heading under 15 miles to Derby — so say roughly how far it went. ## Worthington: what takes place when our engineers get there Our engineers come to your car wherever it has stopped, whether that's outside Worthington School, close to Methodist Chapel or on your own driveway. Both the work and our price depend on three answers — what fluid, what amount, and if it's run — so our technicians ask. You get that price by phone, before anybody sets off. Your system is then flushed thoroughly, once the tank is cleared. AdBlue crystallises and is corrosive to some of the metals in a fuel system, so it doesn't wash out on its own — which is why that counts more here than with petrol. The filter is cleaned, or replaced where it needs to be; clean diesel goes in; and the vehicle is tested. Before we go, we start the car and check that it is running smoothly. Unrun vehicles mostly need a half-hour job after the moment we arrive. The equipment is fine on a busy filling station, and quiet enough for a driveway late at night. Payment happens on the day, not upfront, and you are given the documents your insurer wants: an engineer report and a VAT invoice. While we travel, take a look at your policy; plenty carry cover for misfuelling. ## About Worthington, briefly Worthington is a small village in Leicestershire, situated in the East Midlands region of England, with an elevation of around 89 metres.
