--- title: Upper Wick: AdBlue in a Diesel Tank, Explained canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/upper-wick-worcestershire/ location: Upper Wick county: Worcestershire latitude: 52.176770 longitude: -2.257230 service: AdBlue in a Diesel Tank updated: 2026-10-19 --- # Why It Happens and How to Avoid It: AdBlue in a Diesel Tank in Upper Wick If AdBlue is already in your diesel tank, stop reading for a moment: leave your engine and your ignition off and ring 0333 366 0103. A drain plus a thorough flush, done just where the vehicle sits around Upper Wick, is normally all it takes if caught before your engine runs. Nothing happened yet? Further down, the rest of the page covers the why it happens and the ways to avoid it for good. ## Why does AdBlue in a diesel vehicle need its own filler? Many current diesels on the roads round Upper Wick and Dawshill carry two liquids, not one. Diesel goes to your engine. Its own tank keeps it, and from there it is sent to the exhaust, where spraying treats the gas. Every tank has a filler of its own. Many of vehicles have a single flap for both, while some put the AdBlue filler to your boot or under the bonnet. At the petrol pump, your diesel side gets filled all the time. Rarely filled, AdBlue usually goes in out of a bottle, tipped by someone who has to stop and think what filler it needs. That gap is where the mistake lives. ## Upper Wick: how AdBlue in the diesel tank happens Carelessness rarely causes it. Instead is three things lining up together. Haste comes from the warning. The car tells you as AdBlue runs low, and an empty tank puts it into limp mode — so the top-up gets done in a rush, before work on a drive off Tan House Lane, or heading home in the car park at Whitehall Inn. The old car's filler is where the hand reaches — but a hire car, a new motor or a company car puts the fillers elsewhere. That's a second factor: a strange car. Nothing stops the pour once it has started, because a bottle with a spout goes into a diesel filler as readily as an AdBlue one. The bottle fits. Whether it occurs in Rushwick or the middle of Upper Wick, it is the same few seconds. ## The AdBlue filler and the diesel filler: telling them apart Whether a Upper Wick forecourt or a drive over in Kings End, take a couple of seconds on these before anything goes in. - Check the cap instead of going by where it sits: AdBlue caps are regularly blue or marked "AdBlue", and diesel caps usually are not. - On many cars, size tells: AdBlue gets the smaller filler neck. - Open the flap and look for a label — many vehicles mark what belongs in each filler just there. - Cannot find it beside your diesel inlet? In that case look beneath the bonnet or in your boot — the owner's manual says which. - Picking up a hire or company car, perhaps at the car park outside Worcester Foregate Street? Ask whoever drove the car last before leaving, rather than when the light goes on. ## Topping up AdBlue without it reaching the diesel tank For the day the warning comes on — anywhere it is around Worcestershire — a simple routine to use. - Turn off after you park — flat ground, motor stopped, and not in a rush beside Upper Wick Lane on the verge. - Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds silly and it works. - The diesel cap remains on. Where both sit under a flap, confirm it's shut before lifting the bottle. - Using the bottle's own spout, pour slowly — and stop when it's full or the bottle is empty. - Only after that, start your car: close the cap, check once more, and make sure your diesel cap was never opened. Discover at the second or third step that AdBlue went into the diesel filler? That is where you stop. Don't carry on to stage five. ## Put AdBlue in your diesel tank around Upper Wick already? Brief list, then. First: the motor stays off. Leave the ignition off as well, since on many diesels switching it on by itself starts the pump. Thinning it with extra diesel won't work, because AdBlue settles to the base instead of blending — and that's where your fuel is pulled from. At a forecourt — Texaco, JET or another — the attendants will usually help roll the car away, when you ask. Your own drive in Upper Wick is where it should stay. Stop as soon as it is safe then switch off, if your motor has already run. Upper Wick sits under 5 miles from the M5; there, use the next exit. About how far did it go? Crossing Upper Wick is less a job than a run of under 3 miles to Worcester, so say. ## Upper Wick: what takes place when our technicians arrive Our technicians come to the vehicle wherever it has stopped, whether that is outside Rushwick CofE Primary School, close to Rushwick Village Hall or on your own drive. Both the work and the quote rest on three replies — what liquid, what quantity, and if it has run — so our engineers ask. You hear that quote on the phone, before anybody heads out. Then the tank is emptied and the system rinsed thoroughly. Much more than with petrol, it counts here: the crystals form, certain metals corrode, and none of it washes out unaided, no matter how long it sits. Once the fuel filter has been cleaned — or replaced, where required — clean diesel goes in, and then the car gets tested. Then we fire it up and confirm it runs properly before we leave. Unstarted vehicles usually need a half-hour visit from the moment we arrive. The equipment is fine on a live filling station, and quiet enough for a driveway late at night. Nothing upfront; you settle up that day. Afterwards, a VAT invoice and a report from the engineer are handed to you for your insurer. Plenty of insurance policies include misfuelling cover, and so it's worth checking yours whilst we're on the way. ## About Upper Wick Upper Wick is a small village in Worcestershire, situated on the banks of the River Teme at an elevation of around 25 metres.
