--- title: AdBlue in a Diesel Tank Fotherby? Read This canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/fotherby-lincolnshire/ location: Fotherby county: Lincolnshire latitude: 53.403790 longitude: -0.022030 service: AdBlue in a Diesel Tank updated: 2026-10-14 --- # Why It Occurs and How to Prevent It: AdBlue in a Diesel Tank in Fotherby Keep the motor and ignition off and phone 0333 366 0103 now — reading can wait when AdBlue is already in the diesel tank. Caught before your engine runs, it's usually a drain and a thorough flush, done where your car is around Fotherby. Here before the event? Then what follows covers why it happens and how to prevent it ever happening. ## Two fillers, two tanks: AdBlue in a diesel motor Diesel goes to your engine — yet many modern diesels driven around Fotherby and North Ormsby hold a second fluid too. Stored in a tank of its own, AdBlue is fed into the exhaust gas and cleans it. Each tank comes with one filler of its own. Many of motors share a single flap for the two, while some put the AdBlue filler to the boot or under the bonnet. Diesel goes in at every filling station visit, week in, week out. Seldom topped up, AdBlue normally comes from a bottle, tipped by a driver who must stop and think what cap it needs. The mistake grows in the gap between the two. ## How AdBlue in the diesel tank happens around Fotherby Three things tend to come together, and carelessness is seldom one of them. Haste comes from the warning. The vehicle warns you as AdBlue runs low, and a dry tank sends the vehicle into limp mode — so the top-up happens quickly, before work on a driveway off Louth Road, or on the way home in the car park at the pub in the village. Then, the hand goes for the cap it would have used on the old motor — since a hire car, a new car or a company car puts the fillers where your last one did not. A spout-topped bottle finds no obstacle at a diesel filler no more than at an AdBlue one. So the tip, after started, keeps on. It's a few seconds, be it out in Little Grimsby or right in the heart of Fotherby. ## Telling the AdBlue filler from the diesel filler Before you pour anything, whether on a drive in South Elkington or a forecourt around Fotherby, check these. They take a few seconds. - Blue and lettering: an AdBlue cap is commonly blue, or says "AdBlue", where a diesel cap usually doesn't. Go by the cap, not its position. - Many vehicles give AdBlue the smaller neck of the two. - A label inside the fuel flap frequently says which fuel goes where, on many motors. Look for it. - The handbook says which it lives when the filler isn't next to your diesel cap: the boot, or under the bonnet. - The previous driver knows. Ask when you collect a rental or company car — at Cleethorpes's car park, perhaps — not once the warning appears. ## AdBlue top-ups that never reach the diesel tank When the light goes on, anywhere around Lincolnshire, follow this routine. - Not in a rush on the side of Short Lane, not on a slope, not with the engine running: park and switch off properly. - Say "AdBlue" out loud as you unscrew the cap, once finding the AdBlue filler and reading it. Daft, perhaps, but it does the trick. - If both sit under one flap, check your diesel cap is still closed before you lift the bottle — then leave the vehicle on. - Stop when that tank fills or the bottle runs dry; before that, pour slowly using its own spout. - Only after that, start your car: close the cap, check again, and make sure the diesel cap was never opened. Spot at stage two or three that it's already gone into your diesel side? Then stop just there. Stage five stays out. ## AdBlue in the diesel tank already, in Fotherby? The short order of things, beginning with not starting the motor. The fuel pump starts on many diesels the moment the ignition goes on — so leave it off. Don't top up with diesel to thin it: AdBlue does not mix with diesel, it sinks to the bottom of the tank, where your fuel is pulled from. On a forecourt — BP, Esso or any other — the attendants will usually help roll your car away, when you ask. If you are on your own driveway around Fotherby, leave the vehicle where it stands. Where your motor has run already, stop somewhere safe then switch it off. On the M180, under 25 miles from Fotherby, that means the next junction. Mileage matters — a quick hop across Fotherby makes a smaller job than driving under 25 miles towards Lincoln — so say about how far it went. ## Our arrival around Fotherby, and what happens next Our engineers come to the vehicle wherever it has stopped, whether that's outside Lift Utterby, close to St Mary or on your own driveway. Those replies settle the work and our quote, so our technicians ask what was put in, about how much, and whether it's run. That price comes over the phone, ahead of any van leaving. Emptying your tank comes next, followed by 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. Once the filter is cleaned — or renewed, where needed — clean diesel is added, and then your vehicle gets tested. After that our engineers fire it up and confirm it runs smoothly before we leave. Most jobs are done in roughly half an hour after our technicians get there, as long as your motor hasn't run — and the pumps we use are safe on a busy forecourt and quiet after dark beside a house. Your 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 deposit. It is worth looking at your insurance as the van travels to you: misfuelling cover is included with plenty of policies. ## About Fotherby itself Fotherby is a small village in Lincolnshire, situated in the East Midlands region of England, with a population of around 521 people.
