--- title: Explained: AdBlue in a Diesel Tank Parkstone canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/parkstone-dorset/ location: Parkstone county: Dorset latitude: 50.723110 longitude: -1.951780 service: AdBlue in a Diesel Tank updated: 2026-10-03 --- # How It Occurs and How to Prevent It: AdBlue in a Diesel Tank in Parkstone Pause here for a moment when your diesel tank already holds AdBlue in it: ignition off, motor off, then phone 0333 366 0103. In Parkstone, finding it before your motor runs normally leaves a drain and a full flush on the spot. Here in advance? Then what follows covers why it happens and how to prevent it happening at all. ## Two fillers, two tanks: AdBlue in a diesel motor Plenty of modern diesels in Oakdale, as well as Parkstone, carry on two liquids; your engine takes just your diesel. AdBlue goes to your exhaust, where it is sprayed into the gas to clean it, and it lives in a tank of its own. There's a filler on every tank. Other vehicles keep the AdBlue filler in your boot or under the bonnet; plenty more have the two side by side behind one flap. Topping up the diesel side at the pump happens constantly. Far less often, the AdBlue side gets topped up — mostly from a bottle, by a person working out where it goes. The error lives in that gap. ## Parkstone: how AdBlue in the diesel tank happens Rarely is it carelessness: normally three things coincide. First, the warning. Low AdBlue triggers a warning from the vehicle, and letting it run out means limp mode — hence a hurried top-up, maybe before work off Station Road, or at Dancing Moose on the way home after work. Unfamiliar motors come next, as well. Rentals, new motors and company vehicles place their fillers differently, and habit goes for the cap used on the old one. A spouted bottle meets no obstacle at a diesel filler no more than at an AdBlue one. And so the tip, after begun, carries on. The same few seconds settle it, in the middle of Parkstone or out in Upper Parkstone. ## The AdBlue filler and your diesel filler: telling them apart Before you pour anything, whether on a driveway in Newtown or a forecourt around Parkstone, check these. They take a few seconds. - Where it sits misleads; the cap does not. AdBlue caps are often blue or bear the name "AdBlue" — diesel ones normally don't. - Many cars fit AdBlue the smaller neck of the two. - Look inside your fuel flap: many motors have a label there saying which fuel goes where. - Can't see it next to the diesel inlet? In that case check beneath the bonnet or inside the boot — the owner's manual will say where. - The person who drove the car last. On a hire or company car collected from somewhere like the car park at Parkstone (Dorset), ask before you leave, not when the light comes on. ## How to top up without AdBlue in the diesel tank When the light goes on, wherever in Dorset, use this routine. - Stop on level, engine off, with time in hand — never hurried on the side of Curzon Road. - Say "AdBlue" out loud as you unscrew the cap, after you find the AdBlue filler and reading it. Daft, perhaps, but it works. - Both under one flap? Then confirm the cap on the diesel filler is still closed ahead of lifting the bottle. - Pour slowly, using the bottle's own spout. Stop when it's full or when the bottle is empty. - Before starting the vehicle, shut the cap and check again that your diesel cap never came off. Spot at stage two or three that it's already gone into the diesel side? Then stop right there. Leave out stage five entirely. ## Put AdBlue in your diesel tank around Parkstone already? Brief list, then. Top of that: the motor stays off. The fuel pump runs on plenty of diesels the moment the ignition is switched on — and so keep it off. Filling up with diesel won't weaken it: instead, AdBlue sinks to the bottom of the tank, just where fuel is taken from. At a forecourt — Esso, Shell or another — the staff will normally help push the vehicle clear, if you ask. Leave it where it is if you are on your own drive around Parkstone. If your motor has already run, stop as soon as it is safe and switch off. On the M27, under 25 miles from Parkstone, that means the next exit. Tell us about how far it went: a run towards Salisbury, under 25 miles away, is a bigger job than a short hop across Parkstone. ## When our engineers turn up around Parkstone, what occurs? Anywhere the vehicle has stopped, whether outside Baden-Powell and St Peter's Church of England Junior School, near Parkstone Library or on your own drive, our van comes to it. Our engineers ask what got in, about how much, and if it's run, because the replies determine this work and the quote. On the phone call itself, you hear the quote — before dispatch. Then the tank is drained and the system rinsed thoroughly. AdBlue crystallises and is corrosive to some of the metals in a fuel system, so it doesn't wash out on its own — which is why that matters more here than with petrol. Testing is last: before that, fresh diesel is added, and your filter is cleaned or changed if necessary. Before we go, we fire it up and confirm that it is running correctly. If your engine has not run, the majority of jobs take about half an hour once we are there, using pumps that are safe on a busy forecourt and quiet enough to use outside a house at night. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Before we get there, take a look at your policy; plenty carry cover for misfuelling. ## About Parkstone Parkstone is a coastal locality in Dorset, situated near the shores of Poole Harbour at an elevation of around 19 metres.
