--- title: AdBlue in a Diesel Tank Stoneyhill — Don't Start It canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/stoneyhill-east-lothian/ location: Stoneyhill county: East Lothian latitude: 55.937810 longitude: -3.072550 service: AdBlue in a Diesel Tank updated: 2026-10-14 --- # AdBlue in a Diesel Tank in Stoneyhill? Don't Start It With AdBlue in the diesel tank, your ignition remains off and so does your motor. Urea mixed in water is what AdBlue is. Being water-based, it won't burn and won't blend with diesel; damage just starts when the pump begins pulling it. In Stoneyhill, AdBlue in a diesel tank caught before the engine runs normally means a drain and a thorough flush, right where the vehicle is. Before you do anything else, call 0333 366 0103. ## AdBlue in the diesel tank in Stoneyhill: the first few minutes Things to do: - Pocket your keys, which stops anyone turning the power on. - If you are anywhere near moving traffic, put the hazards on. - The empty bottle or your receipt tells us the product and the amount, and so don't throw it away. - Tell us a postcode starting EH21 6, or whatever street lies closest, and the van reaches you straight — so call from wherever you stand. Things not to do: - Not even briefly, and not to roll your vehicle: your engine stays off. - Plenty of diesels run their fuel pump the instant your ignition goes on, so keep the car off. - Pouring in extra diesel does not help: AdBlue settles out instead of blending. - Never drive it anywhere, not even a short way up Clayknowes Crescent. - By the road, don't attempt draining it yourself. The attendants on duty at any Stoneyhill forecourt — the Shell included — will normally lend a hand pushing it aside if you ask. Parked on your own drive? Then it stays just where it is. ## AdBlue in a diesel tank, and what it does there AdBlue is made for your exhaust, not the motor. From a dedicated reservoir it is fed directly to your exhaust, treating what your engine lets out. Not one side suits the other: urea does not belong in a pump, and a pump can't take urea. Fuel mixes; AdBlue, once tipped in, will not. Its behaviour is not at all like fuel's. The pickup sucks fuel from the lowest part of your tank, and that is precisely where AdBlue ends up: being heavier than diesel, it sinks. The first thing the fuel system pulls through, after it runs, is the AdBlue. So a vehicle that had AdBlue poured in on a drive in Fisherrow last night, and hasn't been started since, is still the easy case: the AdBlue is lying at the bottom of the tank, and nothing has pulled it in. It does two kinds of damage 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 labouring on the components it hits for as long as it stays there. Lines holding AdBlue spell harm overnight for a car parked in Stoneyhill. Only in your tank, it stays stable. Water protects nothing. The injection pump and each injector need diesel flowing past them, and so the water content damages them in its own right. ## Why is AdBlue in a diesel often the bigger fault? A problem of thin fuel is what you get after filling a diesel with petrol from the Tesco. It mixes with the diesel, and while it is in that tank it causes no harm; the damage comes from running your motor on it. AdBlue in a diesel is an issue of the wrong substance altogether. Since it does not burn, running it through is not an option. Whether the vehicle sits in Stoneybank or the heart of Stoneyhill, firing it up "to see" does more harm with AdBlue than nearly any other mistake, and the flush matters more. Why: it won't remain mixed, and so diluting it fails; and crystals and corrosion outlast the next tankful. The same good news holds as with petrol. Anywhere around East Lothian the vehicle has come to rest, an unrun motor means the AdBlue still inside the reservoir: the easiest part of a fuel system to clear. ## AdBlue in a diesel tank in Stoneyhill: how it ends up there It is not on purpose. Many cars keep the AdBlue inlet beside the diesel one, occasionally behind a single flap, and muddling them up is simple after dark. A container picked up when driving home and tipped in at home, rather than at the forecourt, is the usual route. A few familiar ways cover the majority of them. The refill gets hurried outside the local primary school, because the dash lit up with a warning while the kids were dropped in. A bottle is poured in at the end of the day on a drive just off Clayknowes Way. Or a driver new to that flap tops up the car in dim light, stopped in the car park outside Ship Inn. It occurs most in the motors people know least: a hire car, a new car, a company car, or the second motor of a household with one diesel and one petrol. Wherever you're in Stoneyhill or the rest of East Lothian, it is the same slip and the same first answer: leave the vehicle off. ## Already started the engine with AdBlue in your diesel tank around Stoneyhill? The AdBlue has left the tank, then. Given any running, it travels to the injection pump and every injector, after passing via your filter and lines. Watch for rough running, exhaust smoke, lost power, lights on the dash, or a cut-out — returning from Newhailes House & Gardens, say, or part way across Stoneyhill. No starting it again to test: pull over when it is safe, then turn it off. More of that is pulled through with each start. Exit the M8, under 10 miles from Stoneyhill, at the next junction and park safely, rather than carrying on. Every mile pushes the AdBlue further in. That is why a hop across Stoneyhill to park beside Horses and a drive of under 5 miles for Edinburgh are very different jobs. Tell us roughly how far it had come. Wherever your car came to a halt is where all of it gets done, even with more to rinse out after the engine has been run. Spotted soon, it very rarely leaves lasting damage. ## What emptying AdBlue from a diesel involves around Stoneyhill We come to your car, wherever it has stopped around Stoneyhill: a side street close to Stoneyfarm Community Centre, a drive, a lay-by or a forecourt. Before anything else our technicians ask what was put in, roughly how much, and if the motor has been run, since those answers determine the work. The polluted diesel and the urea leave together when that tank is drained, on the spot. Your system is flushed thoroughly, which counts more with AdBlue than with petrol, because what it leaves behind does not rinse out on its own. Testing the car follows at the end, after fresh diesel goes in and your filter is flushed or, if necessary, swapped. About half an hour on site is usual for most jobs where your engine hasn't run. Low-noise enough for use outside a house at night, and fine on a working forecourt, the pumps are explosion-proof. Lastly, your system is bled with fresh diesel. Whether it is a parking space at Musselburgh or a driveway around Stoneyhill, that is where we start the engine and you set off. It is tested on clean diesel to be sure it runs properly before we go. Because the job is done in full where the car is, a garage never comes into it. Afterwards, you are given the paperwork for the insurer: a VAT invoice and a written report from the engineer. ## About Stoneyhill and where it is Stoneyhill is a suburban area located on the coast of East Lothian, sitting at an elevation of 28 metres and approximately 4.6 miles east of Edinburgh.

Each job is different, so no single price would be fair. The price moves first with how long, if at all, your engine has been running, and next with the amount of AdBlue that went in.
