--- title: Saxilby: AdBlue in a Diesel Tank, Explained canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/saxilby-lincolnshire/ location: Saxilby county: Lincolnshire latitude: 53.268900 longitude: -0.664740 service: AdBlue in a Diesel Tank updated: 2026-10-03 --- # Preventing AdBlue in a Diesel Tank in Saxilby: Why It Occurs AdBlue already in the diesel tank? In that case set this page down a moment, leave your ignition and engine off, then call 0333 366 0103. A drain and a full flush, done just where the vehicle sits around Saxilby, is normally all it takes if caught before the motor runs. Nothing happened yet? Further down, the page covers the reasons it takes place and the how to prevent it altogether. ## Why does AdBlue in a diesel car need its own filler? Diesel goes to your motor — yet plenty of current diesels driven round Saxilby and Ingleby carry a second fluid as well. 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 is a filler for every tank. Some motors put the AdBlue filler in your boot or under the bonnet; plenty of others place both side by side behind one flap. Filling your diesel side at the pump goes on constantly. Rarely filled, AdBlue usually comes from a bottle, poured by a driver who must stop and think what filler it needs. Mistakes happen in that gap between the two. ## How does AdBlue in the diesel tank take place around Saxilby? It's seldom carelessness. Three things tend to line up. The warning comes first. As AdBlue runs low the car tells you, and if it runs out altogether, the vehicle goes into limp mode. So the top-up is done in a hurry: on a driveway off High Street before work, or in the car park outside Anglers on the way home. The old car's cap is where the hand goes — yet a hire car, a new motor or a company car keeps the fillers elsewhere. That's a second thing: a new motor. A spouted bottle meets no obstacle at a diesel filler any more than at an AdBlue one. And so the pour, once begun, keeps on. The same few seconds decide it, in the middle of Saxilby or out in Broadholme. ## Which filler is for AdBlue, and which for diesel? Check these before pouring, on a forecourt around Saxilby or a drive out in Broxholme. Seconds, no more. - The cap. The AdBlue cap is regularly blue, or marked "AdBlue". The diesel cap usually isn't. Read it instead of going by position. - Many motors fit AdBlue the smaller filler of the two. - A label inside your fuel flap often shows which fuel goes where, on plenty of cars. Check for it. - The handbook. If the filler isn't by your diesel cap, it's in your boot or under the bonnet, and the handbook says which. - The person who drove the vehicle last. On a hire or company car picked up from somewhere like the car park at the nearest station, ask before you leave, not when the light comes on. ## AdBlue top-ups that never reach the diesel tank On the day the light comes on — anywhere it is around Lincolnshire — a simple routine to follow. - Not in a rush on the side of Sykes Mews, not on a slope, not with your engine running: park and switch off first. - Find the AdBlue filler, check the cap, and say the name "AdBlue" out loud while you unscrew it. It seems silly. It works. - If both sit under one flap, check the diesel cap is still closed before you lift the bottle — then leave the vehicle on. - Using the bottle's own spout, pour slowly — and stop when it is full or the bottle is empty. - Only then, start your car: close the cap, check a second time, and make sure your diesel cap was never opened. If at stage two or three you find you have already poured into the diesel side, stop there. Don't go on to step five. ## AdBlue in your diesel tank already, around Saxilby? Then the order of things is short. Don't start your motor. The fuel pump starts on plenty of diesels the moment your ignition goes on — so keep it off. Don't top up with diesel to thin it: AdBlue does not mix with diesel, it sinks to the bottom of your tank, where the fuel is sucked from. On a forecourt — Shell, BP or any other — the staff will usually help push the car clear, when you ask. Your own driveway around Saxilby is where it stays. When the motor has been run already, pull over somewhere safe and switch it off. On the Doncaster By-Pass, under 25 miles from Saxilby, that means the next junction. Roughly how far did it go? Crossing Saxilby is smaller work than a trip of under 10 miles towards Lincoln, and so tell us. ## When we get there around Saxilby, what occurs? Wherever your car has stopped, be it outside Saxilby Church of England Primary School, beside Saxilby Methodist Church or at home, the van comes to it. Those answers settle the work and our price, so we ask what went in, about how much, and whether it's run. That price is given over the phone, before any van leaves. Emptying your tank comes next, then a thorough flush of your system. With AdBlue that counts more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, so it does not wash out on its own. The filter is cleaned, or replaced where it needs to be; fresh diesel goes in; and the vehicle is tested. Before we leave, our engineers fire it up and make sure that it's running smoothly. With pumps fine on a working forecourt and quiet enough to use outside a house at night, most jobs where your motor hasn't run need about half an hour once our technicians are there. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Misfuelling cover is included in many insurance policies — so use the wait to look at yours. ## About Saxilby, briefly Saxilby is a village situated on the banks of the River Trent in Lincolnshire, with a low elevation of around 11 metres above sea level.
