--- title: Don't Start It: AdBlue in a Diesel Tank Wincanton canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/wincanton-somerset/ location: Wincanton county: Somerset latitude: 51.056090 longitude: -2.411320 service: AdBlue in a Diesel Tank updated: 2026-10-13 --- # AdBlue in the Diesel Tank in Wincanton? Keep It Switched Off If AdBlue has gone into your diesel tank, keep the motor off then leave your ignition off. AdBlue is urea mixed in water. It does not burn, it doesn't mix with diesel, and the damage it does begins when the fuel system draws it in. In Wincanton, AdBlue in a diesel tank found before your engine runs usually means a drain and a thorough flush, right where the car is. Ring 0333 366 0103 before you do anything else. ## Those opening minutes: AdBlue in your diesel tank around Wincanton Things to do: - So nobody can switch the ignition on, pull your keys out. - Put the hazards on if you're anywhere near moving traffic. - Which product, and about how much quantity? Save the bottle or your receipt, and we will know. - The van finds you quickest with a postcode starting BA9 9, or simply the name of a street close by, so call from the spot. Don't do these: - No starting your motor — not briefly, not to reposition your car. - Switching the key to ignition by itself starts your pump going on plenty of diesels. Skip it. - AdBlue does not dilute in diesel — it separates out — so adding more diesel won't weaken it. - Don't drive it anywhere, not even a short stretch up North Street. - No emptying it yourself, at all, at the verge. Rolling the vehicle away from the island is a job for staff to help with, wherever Wincanton forecourt you are on, the Morrisons included. On the drive, the car remains just as it is. ## AdBlue in a diesel tank, and what it does there Not the motor but the exhaust is where AdBlue is meant to go. From a dedicated tank it goes straight to the exhaust, treating what your engine emits. A fuel pump isn't designed to take it, and AdBlue was never supposed to travel through one. Fuel blends; AdBlue, after tipped in, will not. Its behaviour is not at all like diesel's. It is heavier than diesel, so it sinks and collects at the bottom of that tank, which is where the pickup draws fuel from. Easiest of all: a vehicle that had AdBlue in Riding Gate last night and hasn't been started since. The liquid waits at the foot of your tank, undrawn — though it would be the first thing through once the engine starts, ahead of any diesel at all. After it's sucked in, the harm comes in two forms. As its water goes, the urea left behind crystallises, and the crystals block filters and settle in fine passages. And it is corrosive to some of the metals a fuel system is made from, so it keeps working on the components it reaches for as long as it remains there. A car left sitting around Wincanton with AdBlue already in its lines is worse by the morning; one with AdBlue just in its tank isn't. The water in it does damage of its own: the high-pressure pump and the injectors depend on diesel to lubricate them, and water offers them nothing. ## Petrol or AdBlue in a diesel: why AdBlue is often worse Fill a diesel with petrol in error over at the Shell, and this issue is thinned fuel. No harm is done while it stays unused, mixed into your diesel — only when the engine works on it. The trouble with AdBlue in a diesel is a completely wrong substance. It cannot simply be run through, because it does not burn. Whether the car sits in Lattiford or the heart of Wincanton, turning it over "to see" costs more in this case than almost any other error, and the flush counts more. Why: it won't remain mixed, and so diluting it fails; and deposits and corrosion outlast the following fill. With AdBlue, the good news is no different from petrol. Not started? Then the AdBlue sits only in the tank, the simplest bit of the whole system to empty, wherever your vehicle has come to rest in Somerset. ## How does AdBlue end up in a diesel tank around Wincanton? It's not on purpose. Many cars keep the AdBlue cap beside the diesel inlet, occasionally behind one flap, and mixing them up is simple in poor light. It usually takes place outside the house, from a bottle bought on the journey home, not at the filling station. A few familiar ways cover most cases. Rushing, outside Our Lady of Mount Carmel Catholic Primary, after a warning light flashed on during the school run, someone tops up the car. Near Church Street, someone tips a container in on the drive after work. One more pattern: dim light, a pub car park by The Bear Inn, and someone opening that flap the first time. It crops up most in a hire car, a brand-new motor, a fleet motor, or the spare motor of a home with both fuel types — the cars drivers use the least. An identical slip, same first response — keep it switched off — anywhere you are in Wincanton or the remainder of Somerset. ## Started the motor with AdBlue in your diesel tank in Wincanton? Then the AdBlue has left your tank. Your filter and lines have had it pulled through, and some running carries it on to the high-pressure pump and each injector. You may notice the motor running roughly, smoking, losing power, showing warning lights or cutting out, maybe on the way back from Wincanton Sports Ground or halfway across Wincanton. Pull over when safe. Turn off. Leave it off rather than testing it again. Each start pulls more of that through. If you were on the M5, under 25 miles from Wincanton, come off at the next exit and stop somewhere sensible rather than pressing on. Mileage matters: every mile pushes the AdBlue deeper into the system, and so heading towards Wells, under 15 miles away, gives a far larger job than crossing Wincanton to the car park by The Plaza Cinema. Tell us roughly how far it had come. There is more to rinse out once your engine has run, and we do all of it where the vehicle has stopped. Very rarely does it leave long-term damage if it is caught soon. ## Draining AdBlue in a diesel around Wincanton: what it takes The vehicle stays where it is, whether that's a street near St Peter & St Paul, a drive, a lay-by or a filling station around Wincanton, and our van travels to it. Before anything else our technicians ask what was put in, roughly how much, and whether your engine has run, since those answers settle the work. The contaminated diesel and the urea come out as one when that tank is emptied, on the spot. With AdBlue, more so than with petrol, the flush counts: the fuel system is flushed right through because residue will not flush out unaided. A test of your car comes at the end, after fresh diesel is added and the filter is cleaned or, where necessary, replaced. Roughly half an hour on site is usual for most jobs when the engine has not run. Our equipment is explosion-proof, and so a live forecourt is no fault, and it is hushed enough for a residential street late at night. Priming your system with fresh diesel comes at the end. Whether it is a parking bay outside Templecombe or a driveway in Wincanton, that is where our engineers start the engine and you drive off. Before we go, our technicians make sure it is running smoothly with fresh diesel in. The entire job is done where your car is, so it never needs to be taken to a workshop. The insurer is likely to want an engineer's report and the VAT invoice — both yours once this job is done. ## About Wincanton itself Wincanton is a riverside town situated in Somerset, England, with a location that benefits from its proximity to major transport links.

That last one turns on whether a van can reach it safely, and an open driveway is simpler than a tight space behind The Balsam Center.
