--- title: Stoneybank: AdBlue in a Diesel Tank, What Next canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/stoneybank-east-lothian/ location: Stoneybank county: East Lothian latitude: 55.933070 longitude: -3.060080 service: AdBlue in a Diesel Tank updated: 2026-10-23 --- # Stoneybank: AdBlue in the Diesel Tank? Find Your Situation What to do about AdBlue in a diesel tank depends on one thing more than any other: if your engine has been run since it went in. If it hasn't, keep it that way, whether the vehicle is in Stoneybank itself or out in Stoneyhill. Normally this is draining and thoroughly cleaning it right there in Stoneybank — so keep your key and motor off and ring 0333 366 0103. Already run? Stop when safe, then turn it off. A bigger job, yes, yet the identical opening move. Match what happened to a situation from the list below, wherever around East Lothian you are. ## At the petrol pump around Stoneybank: AdBlue in a diesel Picture it: standing by the petrol pump, gripping the bottle, you spot the filler you opened wasn't the correct one. Anywhere around Stoneybank, then — BP, Tesco, or somewhere else close by. What it means: this is the best place to find out. No pump has drawn it through, so the AdBlue sits only inside your tank. Next: avoid the urge to start it just to free up the petrol pump. Ring us from the forecourt after the car sits in a space — the attendants will lend a hand to roll it — then save the bottle. The equipment is explosion-proof and fine on a busy forecourt, so a car that can't be pushed away gets emptied where it is at the petrol pump. ## AdBlue in the diesel tank on a Stoneybank drive? On the dash, a warning had been lit all week. Only at the recycling bin, the empty container in hand, did you look back at the cap you'd used on the drive. Houses just off Mayfield Crescent are caught out as much as anywhere else. The upshot: zero driving since makes it almost equal to finding it at the pump. AdBlue doesn't mix with diesel; it sinks to the bottom of the tank and waits there. Overnight does not change that. Your move: keys indoors, so no one drives your vehicle anywhere at breakfast. Then, phone. Your driveway is where it gets drained, whether in Stoneybank or Monktonhall. Late-night drains outside a house are fine: the pumps are low-noise. ## Set off with AdBlue in a diesel in Stoneybank? Rough running, smoke, falling power or a glowing dashboard started a mile or two beyond the top-up. Perhaps it was on Loretto Court, perhaps on the way out towards Edinburgh, under 10 miles away. In short: the AdBlue has been sucked into the system. Past the filter, along the pipework, and — the more the distance — on into the high-pressure pump and every injector. Each restart, like each mile, pushes it deeper. Next: find a sensible place, stop, then switch the motor off. On the M8, under 10 miles from Stoneybank, that means the next exit, not the services further on. Starting it again to check gets nothing — AdBlue never clears itself. Roughly what distance had it gone? Say so when you phone. ## AdBlue in the wrong tank of a hire, lease or company car A week back, it was new to you. On your own car, AdBlue is absent or somewhere else. On this one, its inlet is right next to your diesel cap — a surprise to you. It can happen to anyone, anywhere across East Lothian. What it means: the same as the situations above, depending on whether it's run, with one more stage. The owner frequently has to sign off the work, under many rental and company agreements. Next: ring the rental company or your fleet manager first, and then us — settling it before we arrive is faster. Leave the car switched off as the answer arrives, even if you're waiting at Musselburgh or close to War Memorial. ## Not sure it was AdBlue in the diesel tank, Stoneybank? At times, "I think so" is the most you can truthfully say. Which cap came off, you can't recall; meanwhile the bottle weighs lighter than it ought to, and a whiff of ammonia hangs by your filler. Perhaps it happened in a hurry at the school gates at the local primary school, or on a friend's drive in Inveresk. What it means: a little spilled around the filler does no damage to your engine. A diesel tank with AdBlue inside is another story. Any AdBlue in the tank will be pulled in by firing up your car, and the start would not settle which it is in any case. Next: act as though it went in, and leave your engine off. Ring us and explain what you saw; we would rather check a tank that turns out free of AdBlue than drain one that has already been run. ## The common ground in every Stoneybank AdBlue drain Whichever scenario you are in, this job starts the same way. Anywhere your car stands — The Riverside Tavern's car park, a road by St Michael's Kirk Inveresk, a drive, a forecourt — our van gets there and we ask for the fluid, the amount, plus whether the motor has turned over. Those replies settle this work, and you get the price on the phone, before anyone heads out. A thorough flush follows this drain. With petrol it is routine; with AdBlue it's essential, because deposits form and some metals are attacked, and none of that washes out unaided. The filter is flushed, or replaced where it needs to be; fresh diesel goes in; and the car is tested. If your engine has not run, most jobs take about half an hour once we are there. Our technicians fire it up at the end. Before our technicians leave, it's checked to confirm it runs correctly on new diesel. If it is noticed soon, the car very seldom has permanent damage, and the entire job takes place where it is. For your insurer: an engineer's report and the VAT invoice. For you: payment that day, no money in advance. Many insurance policies include misfuelling cover, so it's worth checking yours whilst we are on the way. ## About Stoneybank itself Stoneybank is a coastal suburban area in East Lothian, situated near Edinburgh and characterised by semi-detached housing.
