--- title: AdBlue in a Diesel Tank Smithston? Read This canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/smithston-inverclyde/ location: Smithston county: Inverclyde latitude: 55.941410 longitude: -4.802740 service: AdBlue in a Diesel Tank updated: 2026-10-02 --- # Preventing AdBlue in a Diesel Tank in Smithston: Why It Happens Pause reading for a moment when your diesel tank already has AdBlue in it: ignition off, engine off, and phone 0333 366 0103. A drain plus a thorough flush, carried out just where the vehicle sits in Smithston, is normally what it needs when found before your motor runs. Here in advance? In that case the rest covers why it happens and what to prevent it ever happening. ## AdBlue in a diesel vehicle, and its separate tank No single liquid but two: that is what many newer diesels near Smithston and Ravenscraig run, with diesel for the engine. Stored in a tank of its own, AdBlue is sprayed into your exhaust gas to clean it. Each tank comes with a filler of its own. Other cars put the AdBlue filler in the boot or under the bonnet; a lot of others have the two together behind one flap. Topping up your diesel side at the petrol pump happens constantly. The AdBlue side is fuelled far less regularly, normally from a bottle, and normally by somebody who has to stop and think where it goes. The mistake grows in that gap between them. ## How AdBlue in your diesel tank occurs in Smithston Three things tend to come together, and carelessness is rarely one of them. The warning comes first. As AdBlue runs low the car tells you, and if it runs out altogether, the vehicle drops into limp mode. So the top-up is done in a hurry: on a driveway off Sutherland Road before work, or in the car park at The Burns Lounge on the way home. Then the vehicle is new. A hire car, a new car or a company car puts the fillers where your last one didn't, and your hand reaches for the cap it would have used on the old one. Third, the spout fits: diesel filler or AdBlue one, it slides in as easily, and once the tip begins, nothing halts it. Whether it takes place in Fancy Farm or the middle of Smithston, it is the same few seconds. ## Telling the AdBlue filler from the diesel filler Check these before pouring, on a forecourt around Smithston or a driveway over in Gateside. Seconds, that's all. - The cap. The AdBlue cap is often blue, or marked "AdBlue". The diesel cap usually isn't. Read it rather than going by where it sits. - Check the size: the smaller filler neck is, on many motors, the AdBlue one. - The flap. Look inside the fuel flap for a label. Plenty of vehicles say there which fuel goes where. - Cannot find it beside your diesel filler? Then check beneath the bonnet or inside your boot — the handbook will say which. - Collecting a hire or company car, say at the car park outside Branchton? Ask whoever drove the car last before you set off, not when the light comes on. ## How to top up without AdBlue in your diesel tank A routine for the day the light comes on, wherever in Inverclyde that is. - Stop somewhere level, motor off, with time to spare — not rushing on the side of Gleninver Road. - Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds daft and it does the trick. - Leave your diesel cap on. If both sit under one flap, check the diesel cap is still closed before you lift the bottle. - Stop when that tank is topped up or the bottle runs dry; until then, pour slowly through the own spout. - Close the cap and check once more. Make sure your diesel cap was never opened. Only then start your car. If at stage two or three you find you have already poured into the diesel side, stop there. Never go on to step five. ## Put AdBlue in the diesel tank around Smithston already? Then the order of things is short. Do not start the engine. On plenty of diesels the ignition alone runs the fuel pump, and so don't switch it on. Thinning it with more diesel fails, because AdBlue sinks to the base rather than blending — and that's where the fuel is drawn from. At a forecourt — BP, Tesco or another — the staff will normally help push the vehicle away, when you ask. On your own drive in Smithston? Then the car remains where it is. When your motor has run already, stop safely and switch it off. Leave the M8 — under 10 miles out of Smithston — at the first exit. About how far did it go? Hopping across Smithston is smaller work than a run of under 25 miles towards Glasgow, and so tell us. ## What takes place when our technicians get there around Smithston Anywhere the vehicle came to rest, whether by the local primary school, near Ravenscraig Stadium or at home, our van comes to it. Both the work and our price rest on three replies — what liquid, what amount, and if it has run — so we ask. You get that quote by phone, before anybody sets off. Your system is then rinsed thoroughly, after your tank is emptied. With AdBlue that matters more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, and so it doesn't wash out on its own. Once the filter is cleaned — or renewed, if needed — clean diesel goes in, and then the car gets tested. Before leaving, our technicians start it and check that it's running correctly. If your engine has not run, the majority of jobs take about half an hour once we are there, using pumps that are fine on a working forecourt and quiet enough to use outside a house at night. Paying happens on the day, not upfront, and you receive the documents your insurer asks for: an engineer report and a VAT invoice. Wrong-fuel cover is part of plenty of insurance policies — and so use the wait to look at yours. ## About Smithston, briefly Smithston is a suburban area in Inverclyde, situated on the coast of Scotland, with Fancy Farm and Branchton nearby.
