--- title: AdBlue in a Diesel Tank Old Town: What Now canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/old-town-dorset/ location: Old Town county: Dorset latitude: 50.714050 longitude: -1.986190 service: AdBlue in a Diesel Tank updated: 2026-10-04 --- # AdBlue in the Diesel Tank in Old Town: What Now? One fact counts above all once AdBlue is in a diesel tank, and it is if your engine has been started since. Not started yet? Then leave it like that, wherever the vehicle is — Old Town or Longfleet. Normally that means emptying and thoroughly cleaning it on the spot around Old Town — so keep the key and engine off and ring 0333 366 0103. Where the engine has run, stop somewhere safe first, then switch it off. A larger job, then, but the same opening step. Find the scenario below that matches yours, wherever around Dorset it happened. ## Old Town forecourt: AdBlue in a diesel at the pump Picture it: standing by the pump, holding the nozzle, you realise the cap you opened was not the correct one. It might be the BP, or perhaps the Esso, or another station around Old Town. In short: there is no better spot to be to spot it. Nothing has drawn it in, and so the AdBlue sits only in your tank. Freeing the pump is no reason to run it — and so don't get back in. Ask the attendants to help you push the vehicle into a parking bay, keep your receipt or the bottle, and ring us from the forecourt. Can't move the car beside the petrol pump? Explosion-proof equipment keeps a live forecourt safe, so it can be drained where it is. ## AdBlue in your diesel tank on a Old Town drive? On your dash, a warning had shown all week. Only by the recycling, the empty bottle in hand, did you glance back at the cap you had used at the driveway. Right off High Street is no less likely from any other place. Put simply: if your vehicle has not moved since, it's nearly equal to spotting it at the pump. AdBlue does not mix with diesel; it sinks to the bottom of your tank and waits there. Overnight doesn't change that. Keep your keys indoors overnight — or someone might drive it away first thing — and phone us. Poole or Old Town: wherever your drive is, that is where it gets drained. Even at night, the pumps are quiet enough for a residential street. ## Drove off with AdBlue in a diesel in Old Town? Topped up, pulled away, and soon your motor was turning unevenly, smoking, losing power, or lighting up your dash. New Orchard, perhaps, or the way to Salisbury — a run of under 50 miles. Meaning? The fuel pump has taken the AdBlue in. Past the filter, through the pipework, and — the further the distance — on into the high-pressure pump and each injector. More driving, more restarts: further it goes. Next: pick a sensible spot, pull in, and switch the motor off. On the M27, under 25 miles from Old Town, that means the next junction, not the services further on. No test restarts: clearing itself is not something AdBlue will do. Tell us know the mileage covered as you call. ## AdBlue in the wrong tank of a hire, lease or company car It is a motor you have had for a week. Unbeknown to you, the AdBlue and diesel inlets sit side by side here — not like your own vehicle, which has no AdBlue or keeps it in another spot. Throughout Dorset, no one is safe from it. Meaning? Whatever applies above applies here — run or unrun — plus one further stage. Plenty of hire and company agreements want the owner to approve work on the vehicle. Next: phone the rental company or your fleet manager first, then us — settling it before we arrive is quicker. Hanging on for an answer at the car park at Poole, or near Salvation Army? Leave the car off throughout. ## Unsure about AdBlue in your diesel tank around Old Town? "I think so" is sometimes the most honest answer there is. The bottle is lighter than it should be, there's a faint smell of ammonia about your filler, and you can't remember which cap you took off. The gates of Old Town Infant School and Nursery in a hurry, perhaps, or a friend's driveway over in Hamworthy. In short: spillage near the filler does your engine unharmed. AdBlue inside the diesel tank does. You cannot tell which by turning the ignition, and doing so will suck in any AdBlue that is in that tank. Your move: act as if it got in, and don't start your motor. Inspecting a tank that proves free of AdBlue is better than emptying one once it has been run — so phone then describe to us what you saw. ## Every AdBlue drain in Old Town shares these steps The job begins identically, whatever your situation. Wherever the car stands — The Brewhouse's car park, a road beside Skinner Street United Reformed Church, a driveway, a forecourt — our van arrives and we ask for the fluid, the amount, plus if the engine has turned over. Answers shape the work; the price comes on the call whilst nobody has left yet. Then your tank is cleared and the system rinsed thoroughly, which matters more with AdBlue than with petrol: AdBlue crystallises and is corrosive to some of the metals in a fuel system, so it does not rinse out on its own. Clean diesel goes in after the filter has been flushed or changed, and your car is then checked. If your engine has not run, most jobs take about half an hour once we're there. The last step is firing it up. With new diesel in, it runs while we confirm it is running smoothly, and then we head off. Our engineers do the entire job where the vehicle is, and permanent damage is very uncommon when it has been caught soon. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Check your insurance while we arrive: cover for misfuelling is built into many policies. ## About Old Town itself Old Town is a coastal suburban area in Dorset, situated near the shores of Poole Harbour. Old Town sits at a low elevation of around 4 metres, close to nearby places like Poole and Lower Hamworthy. Old Town is characterized by its predominant housing type, which is mainly flat. Old Town is located approximately 26 miles from Salisbury and 97.5 miles from London. ## AdBlue drains around Old Town and across Dorset Lower Hamworthy and Sterte have the same teams as Old Town, a residential suburb, plus further towns over BH postcodes. A postcode starting BH15 1 is the quickest way to tell us where you are. No moving is required, whether stopped in the centre of Old Town or on a lay-by heading to Sterte Green, and so keep it where it is. Where it sits, that's where it is drained. Phone and ask instead of guessing if you're by Baptist Church, on a boundary, or somewhere awkward to pin down. ## In one line: your situation If it has not run, ring and leave it off. Whichever case fits, Petrol in Diesel handles the rest on 0333 366 0103, throughout Dorset and within Old Town — after you stop, turn off and ring, if it has run.
