--- title: AdBlue in a Diesel Tank Thrussington? Read This canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/thrussington-leicestershire/ location: Thrussington county: Leicestershire latitude: 52.737870 longitude: -1.042530 service: AdBlue in a Diesel Tank updated: 2026-10-26 --- # How It Happens and How to Prevent It: AdBlue in a Diesel Tank in Thrussington Pause here for a moment if the diesel tank already has AdBlue in it: ignition off, motor off, then phone 0333 366 0103. Caught before the engine runs, it's usually a drain and a thorough flush, done where your car is in Thrussington. The remainder of this page covers why it takes place and how to ensure it doesn't — useful if you're reading ahead of time. ## Why does AdBlue in a diesel vehicle need its own filler? No single fluid but two: that is what plenty of newer diesels near Thrussington and Hoby run, with diesel for your motor. AdBlue's own tank keeps it, and from there it goes to your exhaust, and there a spray cleans the gas. Every tank has a filler of its own. Some vehicles put the AdBlue filler in the boot or under the bonnet; a lot of others place both together under one flap. The diesel side is fuelled at the petrol pump all the time. The AdBlue side is topped up far less commonly, usually from a bottle, and normally by someone who has to stop and think where it goes. It is in that gap that the error lives. ## AdBlue in the diesel tank around Thrussington: how it happens It's hardly ever carelessness. Three things tend to line up. Hurry follows from the warning. The car tells 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 Old Gate Road, or on the way home in the car park outside Star Inn. Next, your hand reaches for the cap it would have used on the old car — because a hire car, a new car or a company car puts the fillers where your last one did not. A spouted bottle finds no resistance at a diesel filler any more than at an AdBlue one. So the pour, after started, keeps on. The same few seconds decide it, in the middle of Thrussington or out in Rearsby. ## Which filler is for AdBlue, and which for diesel? Check these first, at a forecourt around Thrussington or a drive out in East Goscote. A few seconds, that's all. - Where it sits can mislead; the cap doesn't. AdBlue ones are often blue or carry the word "AdBlue" — diesel caps normally don't. - Check the size: the smaller filler neck is, on many vehicles, the AdBlue one. - A label inside the fuel flap frequently shows which fuel goes where, on many motors. Look for it. - The handbook. If your filler isn't by the diesel cap, it is in your boot or under the bonnet, and the handbook says which. - Check with the person who drove it last — before you leave, not when the light comes on — when you collect a hire or company car from somewhere like the car park at Sileby. ## Topping up AdBlue without it reaching your diesel tank Wherever across Leicestershire the light comes on, this is a routine for that day. - Not in a rush on the side of Blacksmiths Close, not on a slope, not with your engine running: park then switch off properly. - Say "AdBlue" out loud as you unscrew the cap, once you find the AdBlue filler and read it. Daft, yes, but it works. - Leave the diesel cap on. If both sit under one flap, check the diesel cap is still closed before you lift the bottle. - Stop once your tank fills or the bottle is empty; before that, tip gently through the built-in spout. - Shut the cap, and look once more — confirm your diesel cap remained shut the whole time. Only then, start the vehicle. If at stage two or three you find you have already poured into your diesel side, stop there. Don't go on to stage five. ## Thrussington: already put AdBlue in the diesel tank? Don't start the motor: that is how the short order of things begins. Don't switch the ignition on; on plenty of diesels that alone runs the fuel pump. AdBlue does not mix with diesel — it sinks to the bottom of the tank, where your fuel is drawn from — so don't top up with diesel to thin it. Ask the staff to help roll your car away from the petrol pump if you're at a forecourt — the Shell, the BP or anywhere else. If you're on your own drive in Thrussington, leave the vehicle where it is. If the motor has already run, stop as soon as it is safe and switch off. Thrussington sits under 10 miles from the M1; there, take the first exit. About how far did it go? Hopping across Thrussington is less work than a trip of under 10 miles towards Leicester, so say. ## Thrussington: what happens when our technicians arrive Outside Thrussington Church of England Primary School, close to Holy Trinity or on your own drive: wherever your car has stopped, our engineers come to it. We ask what got in, roughly how much, and if it's run, since the answers decide this work and our price. Nobody sets off until you've had our price by phone. Emptying that tank comes next, followed by a full flush of the system. More than with petrol, it matters with AdBlue: the crystals build up, some metals corrode, and none of it clears away on its own, no matter how long it is left. The filter is cleaned, or replaced where it needs to be; fresh diesel goes in; and the car is tested. We do not leave until it has been fired up and is running correctly. Most jobs are done in roughly half an hour after we arrive, provided the motor hasn't run — and the pumps our engineers use are safe on a busy forecourt and quiet at night beside a house. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Many insurance policies include misfuelling cover, and so it's worth checking yours while we're on the way. ## About Thrussington Thrussington is a small village in Leicestershire, situated on the riverside at an elevation of 62 metres, with detached housing being the predominant type of accommodation.
