--- title: The Rectory: AdBlue in a Diesel Tank? Don't Start canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/the-rectory-lincolnshire/ location: The Rectory county: Lincolnshire latitude: 52.680320 longitude: -0.322550 service: AdBlue in a Diesel Tank updated: 2026-10-28 --- # AdBlue in the Diesel Tank in The Rectory? Keep It Switched Off If AdBlue has gone into the diesel tank, keep your motor off then leave your ignition off. Urea dissolved in water is what AdBlue is. Being water-based, it won't burn and never combines with diesel; trouble only comes once the pump begins pulling it. Caught before your engine has run, AdBlue in a diesel tank is generally a drain and a thorough flush, done where the car is in The Rectory. No step comes before ringing 0333 366 0103. ## AdBlue in your diesel tank in The Rectory: the first few minutes Things to do: - Pocket the keys, which prevents anyone turning the electrics on. - Put the hazards on if you are anywhere close to moving traffic. - Which fluid, and roughly what volume? Save the bottle or your receipt, and we will see. - Ring us from where you are. A postcode starting PE6 8, or the name of the closest street, gets our van to you without a search. Don't: - Moving your car just a short way is no reason to fire up your engine. - Plenty of diesels power their fuel pump the moment your ignition comes on, and so keep the vehicle off. - No extra fuel added. The AdBlue won't mix, so it is wasted. - Keep the vehicle where it is rather than driving it anywhere, even a short distance along Hall Farm. - Don't try to drain it yourself at the roadside. Ask the attendants to help you roll the car away from the island if you're on a forecourt in The Rectory, whether it's the The Co-operative or elsewhere. On your own driveway, do not touch it at all. ## AdBlue in a diesel tank: what it does Not your engine but your exhaust is where AdBlue belongs. From a dedicated tank it is fed directly to the exhaust, cleaning what the engine emits. Not one side fits the other: urea does not belong in a pump, and an injection pump cannot take urea. Fuel blends; AdBlue, after tipped in, won't. The behaviour is nothing like fuel's. The intake sucks fuel from the lowest part of that tank, and that is just where AdBlue settles: being denser than diesel, it sinks. Once the system runs, the AdBlue is first to be pulled through. Before then it sits underneath the diesel, which is why a vehicle filled in Langtoft yesterday and never started remains the simple case, provided no one touches your key. It causes two kinds of harm from there. 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 labouring on the components it gets to for as long as it remains there. Where the AdBlue has reached the pipework, waiting till morning in The Rectory leaves it worse. In the tank only, waiting costs nothing. The water in it causes harm of its own: the high-pressure fuel pump and the fuel injectors depend on diesel to lubricate them, and water offers them nothing. ## AdBlue in a diesel: why it is frequently worse than petrol An issue of thin fuel is what you end up with after fuelling a diesel with petrol from the BP. It mixes with your diesel, and while it is in your tank it does no harm; the harm comes from running your motor on it. With AdBlue in a diesel, the liquid as such is plainly the wrong one. It doesn't burn, and so it cannot simply be run through. Whether the car is in Deeping St James or the centre of The Rectory, turning it over "to see" costs more in this case than almost any other error, and the flush counts for more. Why: it will not remain mixed, and so diluting it fails; and deposits and corrosion survive the next fill. The same good news applies as with petrol. Wherever across Lincolnshire your vehicle has stopped, an unstarted engine leaves the AdBlue still inside the tank: the simplest bit of a fuel system to clear. ## AdBlue in a diesel tank in The Rectory: how it ends up there No one means to do it. The AdBlue filler on many cars sits right next to your diesel filler, occasionally under the same flap, and the two caps can look alike in poor light. Most of the time it takes place with a bottle bought on the way home and poured in on the drive, not at the pump. The ways it happens are few and familiar. Rushing, outside William Hildyard Church of England Primary and Nursery School, after a warning lamp flashed on during the school run, someone refills the car. A bottle is poured in at the end of the day on a drive just off Chestnut Way. Or the vehicle is topped up in the car park at The Vine Inn, in poor light, by somebody who has never opened that flap before. Rented motors, new cars, company motors, or the second vehicle in a family with one of each: the least known cars see it most. Wherever you're around The Rectory or the rest of Lincolnshire, it is the same mistake and the same first answer: leave it off. ## Already started your engine with AdBlue in your diesel tank in The Rectory? Then the AdBlue has left the tank. With any running time, it travels to the high-pressure pump and every injector, after passing via your filter and pipework. Lumpy running, smoke from the exhaust, dropping power, dashboard warnings or stalling: each may appear, perhaps midway across The Rectory or coming back from Rectory Paddock. Stop as soon as it is safe, switch off, and don't restart the car to check. Each start pulls more of that through. On the Great North Road, under 10 miles from The Rectory, the first junction is where to leave, and somewhere sensible is where to park — not driving on. A quick hop across The Rectory to the car park by Green School Hall is one thing; driving for Peterborough, under 10 miles away, is something else, because every mile pushes the AdBlue further in. So mileage matters. Tell us about how far it had come. Once your engine has run, the flush takes in more, and all of it is done where your car has stopped. When it is spotted early, lasting damage is very rare. ## Draining AdBlue in a diesel in The Rectory: what it takes The vehicle remains put, whether that is a road near St Guthlac, a driveway, a lay-by or a filling station in The Rectory, and our van travels to it. What was put in, about the quantity, and whether your motor has turned over: our technicians check first, because those decide the job. Then the tank is emptied where the car waits, and so the contaminated fuel and the AdBlue come out together. With AdBlue, far more than with petrol, the flush counts: the whole system is flushed all the way through because what remains will not wash out by itself. Your filter is flushed, or replaced where it needs to be; clean diesel goes in; and your car is tested. If the motor has not run, the majority of jobs take about half an hour once we arrive. Low-noise enough to use outside a house at night, and fine on a busy forecourt, the pumps are explosion-proof. The last step is to bleed the system on fresh diesel. Firing it up comes next, and then you drive off from where the car is parked, by Stamford or on a drive in The Rectory. Our technicians check it runs properly on fresh diesel before we go. The whole job is done where the vehicle is, so it never has to go to a workshop. You get a VAT invoice and an engineer report after that, which is what insurers ask for. ## About The Rectory and where it is The Rectory is a locality situated on the riverside in Lincolnshire, with an elevation of around 8 metres. The Rectory lies near the city of Peterborough, approximately 8.2 miles away, and is close to nearby places such as Market Deeping and Deeping Gate. The Rectory has a population of around 3618 people and predominantly features detached housing. The Rectory is located in the East Midlands region, about 81.5 miles from London. ## The Rectory and Lincolnshire: AdBlue drains across the area AdBlue jobs around The Rectory are passed to vans that cover the places near it — Market Deeping, Deeping Gate plus Castle End — and most of Lincolnshire beyond, across PE postcodes. Guessing doesn't help close to a county line or anywhere hard to pin down; phone and check. No moving is needed. In The Rectory, a small village, a mobile service works: the vehicle is drained where it stands, whether on a drive, a residential street, a parking area or a forecourt. ## What does AdBlue in a diesel tank cost to sort out around The Rectory? No flat figure could be fair, since every job differs. What moves the cost is, firstly, whether your engine has run and for how long; then how much AdBlue got in; and finally where the vehicle is and whether a van can reach it safely, which is simpler on an open driveway than in a tight space behind Market Deeping Town Hall. That's why every call from The Rectory starts with the same three queries, asked before giving a figure, not after: what got in, how much, and whether it's run. With them, the range narrows to one fixed number. Before a van sets off, you are told the price on the phone. Then payment is on the day, card or by phone, with nothing in advance. Many insurance policies include misfuelling cover, so it is worth checking yours while we're on the way. ## In The Rectory and still beside the vehicle? Then, the most helpful thing to do with your vehicle is to not touch it. Ignition off, motor off, keys out. Call 0333 366 0103: AdBlue, the amount, plus if the engine ran are all our technicians need. Petrol in Diesel handles the remainder across Lincolnshire, The Rectory too.
