--- title: AdBlue in a Diesel Tank Newton: Explained canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/newton-dorset/ location: Newton county: Dorset latitude: 50.922570 longitude: -2.306930 service: AdBlue in a Diesel Tank updated: 2026-10-08 --- # How It Happens and How to Prevent It: AdBlue in a Diesel Tank in Newton Keep your motor and ignition off then phone 0333 366 0103 first — reading can wait if AdBlue is already in the diesel tank. Caught before the engine runs, it is usually a drain and a thorough flush, done where the vehicle is in Newton. Not happened yet? Further down, the page explains the why it happens and the ways to avoid it altogether. ## Two fillers, two tanks: AdBlue in a diesel vehicle Not one liquid but two: that is how many modern diesels around Newton and Broad Oak run, with diesel feeding your motor. Its own tank keeps it, and from there it goes to your exhaust, and there spraying cleans the gas. Every tank has one filler of its own. On a lot of vehicles the two sit side by side under the same flap; on others the AdBlue filler is in your boot or under the bonnet. At the petrol pump, the diesel side gets filled constantly. Rarely filled, AdBlue usually goes in from a bottle, tipped by a driver who has to stop and think what filler to use. The mistake lives in that gap. ## How AdBlue in the diesel tank happens in Newton Rarely is it carelessness: normally three things line up. On a drive off Durrant before work, or in the car park outside The Bull on the way home: that is where the hurried top-up happens. Why the rush? As AdBlue runs low the vehicle warns you, and if it is empty, limp mode kicks in. The old car's cap is where the hand reaches — but a rental car, a new car or a company car puts the fillers somewhere else. That is the second factor: a strange car. Nothing stops the pour after it has started, since a bottle with a spout goes into a diesel filler as easily as an AdBlue one. The bottle fits. Whether it takes place in Sturminster Newton or the middle of Newton, it's the same few seconds. ## Which filler is for AdBlue, and which for diesel? Be it a Newton forecourt or a drive over in Rivers Corner, take a couple of seconds on these before any is poured in. - Check the cap rather than going by position: AdBlue ones are regularly blue or marked "AdBlue", and diesel ones usually are not. - The size. On plenty of vehicles the AdBlue filler neck is the smaller of the two. - Open the filler flap and check for a label — many motors mark which goes in which inlet right there. - Can't find it beside the diesel inlet? In that case look beneath the bonnet or in the boot — the handbook will say where. - Picking up a hire or company car, perhaps at the car park at Templecombe? Check with whoever drove it last before you set off, not when the light comes on. ## Keeping AdBlue out of your diesel tank when you top up For the day the warning appears — anywhere it is around Dorset — a routine to follow. - Park and switch off. Not on a slope, not with the motor running, and not in a rush on the side of B3092. - Locate the AdBlue filler, check the cap, and say the name "AdBlue" out loud as you unscrew it. It seems silly. It works. - Leave the diesel cap on. If both sit under one flap, check your diesel cap is still closed before you lift the bottle. - Tip slowly, using the bottle's own spout. Stop when it is full or when the bottle is empty. - Only after that, start the vehicle: close the cap, check a second time, and make sure the diesel cap was never opened. Stop there if you find, at step two or three, that you've already poured into your diesel side. Leave out stage five altogether. ## AdBlue in your diesel tank already, around Newton? The short order of things, beginning with not starting your engine. Don't switch the ignition on; on many diesels that alone runs the fuel pump. Do not top up with diesel to thin it: AdBlue doesn't mix with diesel, it sinks to the bottom of that tank, where the fuel is pulled from. The attendants at Texaco, G&A Cook or any forecourt will usually help to push the car away when you ask. Leave it where it is if you're on your own drive in Newton. If the motor has already run, stop as soon as it is safe then switch off. The next junction is the place to leave when you're on the M27, under 50 miles from Newton. Roughly how far did it go? Crossing Newton is less work than a trip of under 25 miles towards Salisbury, and so tell us. ## Newton: what occurs when our technicians arrive Wherever your car has stopped, whether outside William Barnes Primary School, near War Memorial or on your own drive, our van travels to it. Our technicians ask what was put in, roughly how much, and whether it's run, since those answers determine the work and the quote. That price comes over the phone, before any van leaves. Next: draining, then a thorough flush of the entire system. AdBlue crystallises and is corrosive to some of the metals in a fuel system, and so it doesn't wash out on its own — which is why that counts more here than with petrol. The filter flushed or, if needed, replaced; clean diesel in; then a check of your vehicle. Your engine is fired up next and tested to confirm it runs properly, all before we go. Using pumps safe on a busy forecourt and quiet enough for use outside a house at night, most jobs where the motor has not run need roughly half an hour once our technicians are there. The insurer will ask for the engineer's report and the VAT invoice, and both are yours at the end. Payment is on the day, with no money upfront. It's worth checking your policy as the van travels to you: misfuelling cover is included with many policies. ## About Newton itself Newton is a suburban area in Dorset, situated on the riverside at an elevation of 47 metres.
