--- title: AdBlue in a Diesel Tank Tostock? Read This canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/tostock-suffolk/ location: Tostock county: Suffolk latitude: 52.237180 longitude: 0.860000 service: AdBlue in a Diesel Tank updated: 2026-10-10 --- # Avoiding AdBlue in a Diesel Tank in Tostock: Why It Happens If AdBlue is already in your diesel tank, stop reading for a moment: leave the engine and the ignition off and call 0333 366 0103. Normally, if the engine has not run, it's emptied and thoroughly purged where the vehicle is in Tostock. Not happened yet? Below, the page explains the reasons it happens and the ways to prevent it for good. ## Two fillers, two tanks: AdBlue in a diesel motor Plenty of newer diesels around Beyton, like those in Tostock, run on two fluids; the motor takes just the diesel. The exhaust, not the motor, is where AdBlue ends up: sprayed into the gas to fresh it, from its own tank. Each tank has its own filler. On a lot of vehicles the two sit side by side under the same flap; on others the AdBlue filler is in the boot or under the bonnet. At the petrol pump, your diesel side is topped up all the time. Someone who has to stop and think where it goes usually fills the AdBlue side, from a bottle, and much less frequently. The mistake lives in that gap. ## How AdBlue in your diesel tank occurs around Tostock Carelessness seldom causes it. What does is three things coming up at once. On a drive off Norton Road before work, or in the car park at The Gardeners' Arms heading home: that is where the hurried top-up takes place. Why the rush? As AdBlue runs low the car tells you, and if it's empty, limp mode follows. Then your car is strange. A hire car, a new car or a company car puts the fillers where your last one didn't, and the hand gets to for the cap it would have used on the old one. Nothing halts the pour after it has started, since a bottle with a spout goes into a diesel filler as readily as an AdBlue one. The bottle fits. It's seconds, be it in Broadgrass Green or bang in the centre of Tostock. ## Which filler is for AdBlue, and which for diesel? Whether a Tostock forecourt or a drive out in Norton, take a couple of seconds over these before anything goes in. - Where it sits misleads; the cap doesn't. AdBlue caps tend to be blue or bear the name "AdBlue" — diesel caps usually don't. - Look at the size: the smaller filler neck is, on plenty of cars, the AdBlue one. - Check inside your fuel flap: many vehicles have a label there saying which fuel goes where. - The handbook. If your filler is not by the diesel cap, it is in your boot or under the bonnet, and the handbook says which. - Collecting a hire or company car, perhaps at the car park at Elmswell? Ask the person who drove it last before leaving, rather than when the light goes on. ## How to top up without AdBlue in your diesel tank For the day the light comes on — wherever it is across Suffolk — a simple routine to use. - Park and switch off. Not on a slope, not with your motor running, and not in a rush on the side of Hollow Lane. - Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds daft and it does the trick. - The diesel cap stays on. When the two share a flap, confirm it is closed before the bottle comes up. - Slowly does it, through the bottle's own spout, until it is full or the bottle runs out. - Before starting the car, shut the cap and check again that your diesel cap was never came off. If at step two or three you find you have already poured into your diesel side, stop there. Stage five stays off limits. ## AdBlue in your diesel tank already, around Tostock? Then the order of things is short. Do not start your engine. Leave the ignition off as well, because on plenty of diesels it alone runs your fuel pump. Don't top up with diesel to thin it: AdBlue doesn't mix with diesel, it sinks to the bottom of the tank, where your fuel is drawn from. On a forecourt — Gulf, EG On the Move or any other — the attendants will normally help roll the vehicle away, when you ask. Leave it where it is if you're on your own driveway in Tostock. If the motor has already run, stop as soon as it is safe then switch off. Tostock sits under 50 miles from the M11; on it, use the first exit. Tell us about how far it went: a run towards Colchester, under 25 miles away, is a bigger job than a short hop across Tostock. ## What occurs when we arrive around Tostock Wherever the car has stopped, be it by Thurston Church of England Primary Academy, near Tostock Village Sign or on your own drive, our van comes to it. Those answers determine the work and our quote, and so our technicians ask what got in, about how much, and if it's run. The price comes over the phone, ahead of any van leaving. Your system is then cleaned thoroughly, after the tank is emptied. Not like petrol, AdBlue leaves crystals and attacks certain fuel-system metals, and neither clears away unaided. That is why it counts more. A test is last: before that, clean diesel is added, and the filter is flushed or changed if necessary. Your engine is started next and checked to confirm it runs properly, all before our technicians leave. Unrun cars mostly mean a half-hour visit after the moment we arrive. The equipment is safe on a live forecourt, and hushed enough for a residential street late at night. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. It is worth checking your policy while we travel to you: misfuelling cover is included with many policies. ## About Tostock Tostock is a small village in Suffolk, situated inland at an elevation of 66 metres, and is characterized by its predominantly detached housing stock.
