--- title: AdBlue in a Diesel Tank Longshaw: What Now canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/longshaw-greater-manchester/ location: Longshaw county: Greater Manchester latitude: 53.514990 longitude: -2.709760 service: AdBlue in a Diesel Tank updated: 2026-10-08 --- # What Now? AdBlue in the Diesel Tank in Longshaw What to do about AdBlue in a diesel tank depends on one thing more than any other: whether your engine has run since it was put in. Wherever the car is — Windy Arbour, Longshaw — never start an engine that hasn't been started yet. Phone 0333 366 0103 with the key and engine both off. Across Longshaw, that is typically drained and cleaned where it stands. Already run? Stop when you safely can, then switch it off. A bigger job, then, yet the identical opening step. Further down: the cases our engineers meet, anywhere across Greater Manchester. Choose yours. ## On a Longshaw forecourt with AdBlue in a diesel The cap you unscrewed was the wrong one — and you only notice it while you're standing at the petrol pump, bottle or the nozzle in hand. Somewhere in Longshaw, then — Esso, Shell, or somewhere else nearby. The point: of every spot to notice, this is the best. Just your tank holds AdBlue; no part beyond it has taken any in. Next: avoid the urge to fire it up just to move away from the petrol pump. Ask the staff to help you push your car into a parking spot, keep the till receipt or the bottle, and phone us from the forecourt. Draining it there at the petrol pump is possible if it cannot be shifted, since the equipment is explosion-proof. ## Longshaw, at home: AdBlue in the diesel tank For days the dashboard had been nagging you. Only at the recycling bin, the empty bottle in hand, did you glance back at the cap you had used on the drive. It happens on drives just off Longshaw Old Road as regularly as anywhere. What it means: if you have not driven since, this is nearly as good as the forecourt. AdBlue doesn't mix with diesel; it sinks to the bottom of the tank and waits there. Overnight does not change that. Your move: the keys in the house, so no one takes your vehicle anywhere at breakfast. Then, phone. Your drive is where it is emptied, be it around Longshaw or Brownlow. Even at night, the pumps are quiet enough for a residential street. ## AdBlue in a diesel and already driving in Longshaw? A mile or two beyond filling up, the motor began playing up: rough running, smoke, less power, warnings on your dash. Maybe driving to Liverpool, under 15 miles away, or simply along Cob Moor Road. What it means: the system has pulled the AdBlue in. The injection pump and each injector get it too on a longer run, once the fuel filter and pipework have had it. Every restart, like every mile, pushes it on. What to do: pull over where it's safe and switch off. Service stations further on are too far: from the M6, under a mile out of Longshaw, take the next junction. Do not restart it to see if it has cleared; it will not have. About how far did it go? Say so as you call. ## Hire, lease or company car with AdBlue in the wrong tank It is a car you have had for a week. Unbeknown to you, the two fillers sit side by side here — unlike your own car, which has none or stores it elsewhere. Anywhere you are in Greater Manchester, every driver could be caught. The point: exactly as above, divided by whether it ran, only with one added stage. Plenty of hire and company agreements require the owner's approval before work. Next: ring the hire company or your fleet manager first, and then us — sorting it before we arrive is quicker. Leave the car off while the answer arrives, whether you are parked outside Orrell or near Totem Pole. ## Longshaw: unsure if it was AdBlue in the diesel tank? "I think so" is sometimes as honest answer there is. The bottle is lighter than it should be, there is a faint smell of ammonia round the filler, and you can't remember which cap you took off. Maybe on a friend's drive in Tontine, or rushing by Orrell Newfold Community Primary School on the school run. Put simply: spillage round your filler does the engine unharmed. The diesel tank with AdBlue in it is another matter. Starting your car will not tell you which, and if there is AdBlue in your tank it will draw it in. Do this: behave as though it got in, and never start your engine. Inspecting a tank that proves free of AdBlue is better than emptying one once it has been run — so ring and describe to us what you noticed. ## Every AdBlue drain in Longshaw shares these stages Whatever the case, one opening is used. Wherever your car is — Hare and Hounds's car park, a road beside Billinge Family Church, a driveway, a forecourt — the van arrives and we ask for the fluid, the quantity, plus if your motor has been run. Those answers settle the work, and you hear the price on the phone, before anyone sets off. AdBlue crystallises and eats at some metals used in fuel systems, and so it does not wash out unaided; that is why the flush, after this drain, counts much more with AdBlue than with petrol. The fuel filter is flushed, or replaced where it needs to be; clean diesel goes in; and the car is tested. Where your motor has not run, allow about half an hour once we arrive, for most cases. The final step is firing it up. Our test that it runs smoothly on fresh diesel comes before our technicians head off. When it is spotted soon, the car very seldom has lasting damage, and the entire job happens where it is. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Worth remembering: many insurers offer misfuelling cover, and so a check of your documents while you wait is worthwhile. ## About Longshaw itself Longshaw is a small village in Greater Manchester, situated inland at an elevation of 128 metres.
