In Rosshall, finding it before your engine turns usually leaves draining and a full flush on the spot. The remainder of this page covers why it takes place and how to ensure it doesn't — handy if you're reading ahead of time. ## Two fillers, two tanks: AdBlue in a diesel car Not one fluid but two: that's what plenty of newer diesels around Rosshall and Penilee carry, with diesel feeding the motor. Stored in a tank of its own, AdBlue is sprayed into your exhaust stream and cleans it. Separate tanks, different fillers. On a lot of cars the two sit side by side under the same flap; on others the AdBlue filler is in your boot or under the bonnet. The diesel side is topped up at the petrol pump all the time. Rarely filled, AdBlue usually goes in out of a bottle, poured by a driver who must stop and think what cap it needs. The mistake lives in that gap. ## AdBlue in your diesel tank around Rosshall: how it occurs Carelessness rarely explains it. What does is three things lining up at once. First, the warning. Low AdBlue triggers a warning from your car, and letting it run out means limp mode — hence a rushed top-up, maybe before work off Cronberry Terrace, perhaps at The Gables on the way home after work. The old car's filler is where the hand goes — but a hire car, a new motor or a company car puts the fillers elsewhere. That's the second thing: a strange motor. Nothing stops 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. The same few seconds decide it, in the middle of Rosshall or out in Crookston. ## Telling the AdBlue filler from your diesel filler Before you tip anything, whether on a driveway in Hillington or a forecourt around Rosshall, check these. They take a couple of seconds. - The cap. The AdBlue cap is commonly blue, or marked "AdBlue". Your diesel cap usually isn't. Read it rather than going by where it sits. - On plenty of cars, the size gives it away: AdBlue has the smaller filler neck. - Open the flap and look for a label — plenty of cars show what goes in which filler just there. - Can't see it next to the diesel filler? Then look below the bonnet or inside the boot — the owner's manual says where. - Collecting a hire or company car, say at the car park outside Crookston? Ask whoever drove the vehicle last before leaving, not once the light goes on. ## AdBlue top-ups that never reach the diesel tank When the light goes on, wherever around Glasgow City, follow this routine. - Stop somewhere level, engine off, with time in hand — not hurried on the side of Cronberry Quadrant. - Daft as it sounds, speaking "AdBlue" out loud while you unscrew the cap works — after you've found your filler and read it. - Both under one flap? So confirm the cap on your diesel filler is still shut ahead of raising the bottle. - Using the bottle's own spout, tip slowly — and stop when it is full or the bottle is empty. - Close the cap and check a second time. Make sure the diesel cap was never opened. Only then start the vehicle. Spot at stage two or three that it's already gone into your diesel side? So stop right there. Don't carry on to step five. ## Rosshall: already put AdBlue in your diesel tank? The short order of things, starting with not starting the motor. On many diesels your ignition alone runs the fuel pump, so do not switch the vehicle on. Topping up with diesel will not thin it: instead, AdBlue drops to the bottom of that tank, just where fuel is taken from. The attendants at Esso, BP or another forecourt will usually help to push the vehicle away if you ask. Your own driveway around Rosshall is the place it stays. Stop as soon as it is safe and switch off, if your motor has already run. On the M8, under 3 miles from Rosshall, that means the next exit. Tell us about how far it went: a run towards Glasgow, under 10 miles away, is a bigger job than a short hop across Rosshall. ## When our technicians arrive in Rosshall, what happens? Outside the local primary school, near Ralston Training Complex or on your own driveway: wherever the vehicle has stopped, our technicians come to it. Which liquid got in, the quantity, and if it ran: our technicians ask because those replies set both work and price. The quote is given on the call, before any van leaves. Emptying that tank comes next, followed by a full flush of the 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. A test is last: before that, clean diesel goes in, and the fuel filter is cleaned or replaced as needed. We don't leave until it has been started and is running properly. Most jobs are finished in roughly half an hour after we arrive, provided the engine hasn't run — and the pumps our technicians use are fine on a live 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. Wrong-fuel cover is part of plenty of insurance policies — and so make use of the wait to look at yours. ## About Rosshall and where it is Rosshall is a suburban area located on the riverside in Glasgow City, with an elevation of 21 metres above sea level.
