--- title: Gibshill: AdBlue in a Diesel Tank, Explained canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/gibshill-inverclyde/ location: Gibshill county: Inverclyde latitude: 55.935350 longitude: -4.717080 service: AdBlue in a Diesel Tank updated: 2026-10-21 --- # Preventing AdBlue in a Diesel Tank in Gibshill: Why It Occurs If AdBlue is already in your diesel tank, stop reading for a moment: leave the engine and the ignition off then phone 0333 366 0103. A drain plus a thorough flush, done just where the car stands in Gibshill, is normally all it takes when caught before the motor runs. Here before the event? In that case the rest covers how it comes about and how to stop it ever happening. ## AdBlue in a diesel motor, and its separate tank Many newer diesels around Lilybank, like those in Gibshill, carry on two liquids; your engine takes only the diesel. Its own tank holds it, and from there it is sent to your exhaust, where a spray cleans the gas. There's a filler for each tank. Some vehicles keep the AdBlue filler in your boot or under the bonnet; a lot more place both together under one flap. The diesel side is topped up at the petrol pump all the time. The AdBlue side is fuelled far less often, normally from a bottle, and usually by a person who has to stop and think where it goes. The slip lives in that gap. ## Gibshill: how AdBlue in the diesel tank occurs Three things tend to come together, and carelessness is seldom one of them. On a drive off Bell Street before work, or in the car park at The Waterwheel heading home: that's where the rushed top-up takes place. Why the rush? As AdBlue gets low your car tells you, and once it's gone, limp mode follows. New-to-you motors are next, as well. Rentals, new motors and company vehicles put their fillers in new places, and habit goes for the cap it used on the old one. No part halts the tip after it has started, since a bottle with a spout goes into a diesel filler as easily as an AdBlue one. The bottle fits. The same few seconds settle it, in the middle of Gibshill or out in Ladyburn. ## How to tell the AdBlue filler from the diesel one Look at these before pouring, on a forecourt in Gibshill or a driveway out in Bridgend. Seconds, that's all. - Read the cap instead of going by where it sits: AdBlue caps are commonly blue or marked "AdBlue", and diesel ones usually aren't. - Check the size: the smaller filler neck is, on plenty of motors, the AdBlue one. - The flap. Look inside your fuel flap for a label. Many cars say there which fuel goes where. - Cannot find it next to the diesel filler? In that case look beneath the bonnet or in the boot — the owner's manual will say where. - Check with the person who drove it last — before you leave, not when the light comes on — if you collect a hire or company car from somewhere like the car park at Bogston. ## AdBlue top-ups that never reach your diesel tank Anywhere around Inverclyde the light comes on, here is a routine for the day. - Park and switch off. Not on a slope, not with your motor running, and not in a rush on the side of Cedar Crescent. - Daft as it sounds, saying "AdBlue" out loud as you unscrew the cap works — once you've found the filler and read the cap. - The two behind one flap? So make sure the lid on your diesel side stays closed before lifting the bottle. - Using the bottle's own spout, tip slowly — and stop when it is full or the bottle is empty. - Shut the cap, and look again — confirm the diesel filler remained shut throughout. After that, start the vehicle. Spot at step two or three that it has already gone into the diesel side? So stop just there. Skip step five altogether. ## AdBlue in the diesel tank already, in Gibshill? What follows is a short order of things, starting with no starting your motor. The fuel pump starts on plenty of diesels the moment your ignition is switched on — and so keep it off. Diluting it with extra diesel won't work, because AdBlue sinks to the bottom instead of mixing — and that is where your fuel is sucked from. Ask the staff to help roll the car away from the pump if you are at a forecourt — the Tesco, the Morrisons or anywhere else. Your own driveway in Gibshill is the place it stays. If the engine has already run, stop as soon as it is safe and switch off. Gibshill lies under 10 miles from the M8; on it, use the next exit. Roughly how far did it go? Hopping across Gibshill is less work than a run of under 25 miles towards Glasgow, so say. ## When we turn up in Gibshill, what occurs? Our technicians come to the vehicle wherever it has stopped, whether that's outside the local primary school, near Inverclyde Indoor Bowling or on your own driveway. Those replies settle this work and our price, so we ask what got in, about how much, and if it has run. You get that price on the phone, before anyone sets off. Draining that tank comes next, followed by a thorough flush of the fuel system. With AdBlue that counts 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. Filter cleaned or, if it must be, replaced; clean diesel in; then a check of your car. Before we leave, our engineers start the car and make sure that it's running correctly. Unrun cars usually mean a half-hour visit from the moment we arrive. The equipment is fine on a live forecourt, and hushed enough for a driveway late at night. Payment happens on the day, not upfront, and you are given the documents your insurer wants: an engineer report and a VAT invoice. Many insurance policies include misfuelling cover, so it is worth checking yours while we're on the way. ## About Gibshill Gibshill is a suburban area in Inverclyde, situated on the coast of Scotland, with a mix of semi-detached housing and other residential properties.
