--- title: Pismire Hill: AdBlue in a Diesel Tank? Don't Start canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/pismire-hill-south-yorkshire/ location: Pismire Hill county: South Yorkshire latitude: 53.421340 longitude: -1.447480 service: AdBlue in a Diesel Tank updated: 2026-10-06 --- # AdBlue in a Diesel Tank in Pismire Hill? Don't Start It AdBlue in the diesel tank? Then keep the engine off — and your ignition as well. In plain terms, AdBlue is just urea in water. The harm starts once it is pulled through the lines — it won't ignite, and it will not combine with diesel. A drain and a thorough flush, done where the car is around Pismire Hill, is usually what AdBlue in a diesel tank needs — if it's caught before your motor has been run. Phone 0333 366 0103 before you do anything else. ## What to do straight away, Pismire Hill: AdBlue in your diesel tank Do these: - Pocket the keys, and that prevents anyone switching the electrics on. - If you're anywhere near moving traffic, put your hazards on. - Which fluid, and roughly what amount? Save the bottle or the receipt, and our technicians will know. - Call us from where you are. A postcode starting S5 6, or the name of the nearest street, brings our van to you without a search. Not to do: - Not even for a second, and not to shift the car: your engine remains off. - Don't switch your ignition on. On plenty of diesels that alone runs the fuel pump. - AdBlue doesn't mix in diesel — it separates out — so adding extra fuel won't thin it. - Even a short stretch along Sicey Avenue is too far to drive the vehicle. - Don't try to drain it yourself at the roadside. Moving your vehicle off the island is a job for staff to help with, wherever Pismire Hill forecourt you're on, the JET or any other. On your own driveway, don't move it at all. ## What AdBlue does in a diesel tank AdBlue is made for your exhaust, not the engine. From a dedicated reservoir it is fed straight to the exhaust, treating what your motor emits. Neither side suits the other: urea doesn't belong in an injection pump, and an injection pump can't deal with urea. It does not combine. Once it's poured into a tank of diesel, AdBlue acts not at all like fuel. It's heavier than diesel, so it sinks and gathers at the bottom of your tank, which is where the pickup pulls fuel from. The first thing the fuel system pulls through, once it runs, is the AdBlue. So a motor that had AdBlue poured in on a drive in Shiregreen last night, and hasn't been started since, is still the easy case: the AdBlue is lying at the bottom of your tank, and nothing has pulled it in. 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's corrosive to some of the metals a fuel system is made from, so it keeps working on the parts it hits for as long as it remains there. If the AdBlue is in the lines, leaving it overnight around Pismire Hill makes it worse. In the tank only, time costs nothing. Then there is the water: it offers no lubrication to the parts that need it most — the high-pressure pump and every injector. ## AdBlue in a diesel: why it is frequently worse than petrol An issue of thin fuel is what you end up with from fuelling a diesel with petrol from the Texaco. No harm is done while it stays put, mixed into the diesel — only when your engine runs on it. AdBlue in a diesel is a fault of the wrong substance altogether. It can't just be run through, since it doesn't burn. Crystals and corrosion remain after the following tankful, and AdBlue separates back from the diesel, so watering it won't work. That is why the flush matters so much, and trying your engine "to see" costs more here than almost any other slip — in Wincobank or the heart of Pismire Hill equally. As with petrol, there's good news. Never started? Then the AdBlue sits just inside the tank, the easiest section of the whole system to clear, anywhere the car has come to rest in South Yorkshire. ## How AdBlue ends up in a diesel tank around Pismire Hill No one means to do it. The AdBlue filler on plenty of motors rests right next to your diesel filler, occasionally under the same flap, and the two caps can look alike in poor light. Usually it is not the forecourt: a driver picks up a bottle driving home and tips it in outside the house. The ways it occurs are few and familiar. Midway through the drop-off, the dashboard flags it up, and outside Hatfield Academy the top-up is hurried. Near Rolleston Road, a driver pours a bottle in at home after work. Or the vehicle is topped up in the car park at Ecco Tap Bar, in poor light, by someone who has never opened that flap before. It comes up the most in a rental, a brand-new vehicle, a company car, or the spare motor of a home with one of each fuel types — the vehicles people use least. Leave it switched off: that is the first response to an identical slip, wherever around Pismire Hill or the remainder of South Yorkshire you happen to be. ## AdBlue in your diesel tank around Pismire Hill, and the engine started? If so, the AdBlue is no longer inside the tank. It's been pulled through your filter and the fuel lines, and if the engine ran for any time, it has reached your high-pressure pump and the fuel injectors. Perhaps returning from Bellhouse Road Playing Fields, or part way across Pismire Hill, your engine may run lumpy, smoke, drop pace, light up your dash or stall. Pull over when safe. Turn off. Leave the vehicle off rather than restarting it to check. Every start pulls more of that through. If you were on the M1, under 3 miles from Pismire Hill, come off at the next junction and stop somewhere safe rather than pressing on. How far it went counts. A couple of hundred yards across Pismire Hill to the car park by The Sun Apple is a very different job from a run towards Sheffield, under 3 miles away, with the AdBlue reaching further into your system with each mile. About how far it had come is worth telling us. Wherever the car came to a stop is where all of it gets done, even with more to flush after your engine has been started. Noticed quickly, it very seldom leaves lasting damage. ## What does an AdBlue drain on a diesel involve around Pismire Hill? The car remains put, whether that is a street near Stubbin Neighbourhood Association, a drive, a layby or a forecourt in Pismire Hill, and our van comes to it. The job depends on three replies, which our technicians ask for before all else — which fluid got in, the amount, and if your motor has turned over. Then the tank is cleared where the car sits, and so the contaminated fuel and the AdBlue come out together. With AdBlue, far more than with petrol, flushing counts: the fuel system is cleaned all the way through because what remains won't flush away by itself. Next, the filter: flushed, or replaced if it has to be. Then clean diesel, and then a check of your vehicle. Most of these jobs are a half-hour job once our engineers get there, if the motor hasn't run. The pumps are explosion-proof, safe on a busy forecourt and quiet enough to use outside a house at night. Clean diesel goes in to prime the system, and that is the last step. Then we fire it up and you head off, whether from a parking space outside Meadowhall or a driveway in Pismire Hill. We check it runs smoothly on clean diesel before we go. No workshop is required at any point, with the entire job done then and there. The insurer will want an engineer's report and the VAT invoice — both yours once this job is done. ## About Pismire Hill and where it is Pismire Hill is a suburban area located near Sheffield in South Yorkshire, sitting at an elevation of 128 metres.
