If AdBlue is already in your diesel tank, stop reading for a moment: leave your engine and your ignition off and call 0333 366 0103. Caught before your engine runs, it is usually a drain and a thorough flush, done where the vehicle is around Green Hill. If you are reading before it has happened, the rest of this page is about why it occurs and how to make sure it does not. ## AdBlue in a diesel vehicle: two tanks, two fillers Many current diesels on the roads around Green Hill and Peterhead carry two liquids, not one. Diesel goes to the engine. Your exhaust, not the motor, is where AdBlue goes: dosed into the fumes to clean them, from its own tank. Different tanks, separate fillers. Under one flap, next to each other: that's the layout on a lot of vehicles. Elsewhere, AdBlue's filler sits under the bonnet or in your boot instead. At the pump, your diesel side gets filled all the time. Seldom filled, AdBlue usually comes out of a bottle, poured by a driver who has to stop and think which filler to use. That gap is where the error lives. ## How does AdBlue in the diesel tank happen in Green Hill? Three things tend to come together, and carelessness is rarely one of them. First, the warning. Low AdBlue triggers a message from the car, and running dry means limp mode — so a rushed top-up, maybe before work off Castle Street, perhaps at Caley Bar and Cube Disco on the way home that evening. Next, the hand goes for the cap it knew on the old motor — since a hire car, a new motor or a company car places the fillers somewhere your last one didn't. A spouted bottle finds no resistance at a diesel filler no more than at an AdBlue one. So the tip, after started, carries on. It's seconds, be it out in Keith Inch or bang in the centre of Green Hill. ## Telling the AdBlue filler from your diesel filler Before you pour anything, whether on a driveway in Buchanhaven or a forecourt in Green Hill, check these. They take a couple of seconds. - Check the cap instead of going by where it sits: AdBlue ones are frequently blue or marked "AdBlue", and diesel ones normally aren't. - Plenty of vehicles fit AdBlue the smaller filler of the two. - Open the flap and look for a label — plenty of cars show what goes in which filler just there. - Can't find it next to your diesel inlet? In that case check beneath the bonnet or inside 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 the nearest station. ## How to top up without AdBlue in your diesel tank When the light comes on, anywhere across Aberdeenshire, use this routine. - Turn off after you park — flat ground, motor off, and never in a rush beside Greenhill Road on the verge. - Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds daft and it works. - Both under one flap? So confirm the cap on the diesel side stays closed ahead of raising the bottle. - Slowly is best, through the bottle's own spout, until it is full or the bottle is empty. - Close the cap and check a second time. Make sure your diesel cap was never opened. Only then start the vehicle. If at stage two or three you find you have already poured into the diesel side, stop there. Skip stage five entirely. ## Green Hill: already put AdBlue in your diesel tank? Then the order of things is short. Do not start the engine. Do not switch your ignition on; on plenty of diesels that alone runs the fuel pump. AdBlue doesn't mix with diesel — it sinks to the bottom of your tank, where your fuel is sucked from — so do not top up with diesel to thin it. Ask the attendants to help push the car away from the petrol pump if you are on a forecourt — the Morrisons, the Esso or somewhere else. On your own drive around Green Hill? So your car stays where it is. Stop as soon as it is safe then switch off, if the motor has already run. On the M90, over 50 miles from Green Hill, that means the next junction. Tell us about how far it went: a run towards Aberdeen, under 50 miles away, is a bigger job than a short hop across Green Hill. ## Green Hill: what occurs when our technicians turn up Wherever your car has stopped, be it by the local primary school, near Reform Monument or on your own drive, our van travels to it. Those answers decide the work and our price, and so our engineers ask what was put in, about how much, and whether it has run. On the call itself, you hear our price — before anything else. Next: draining, then a thorough flush of the entire system. Unlike petrol, AdBlue forms crystals and eats at certain fuel-system metals, and neither clears away unaided. Hence it counts more. A test comes last: before that, fresh diesel goes in, and your filter is cleaned or changed as needed. Next our engineers start the car and confirm it runs properly before leaving. Using pumps safe on a busy forecourt and quiet enough to use outside a house at night, most jobs in which the motor hasn't run need roughly half an hour after our technicians are there. Payment happens on the day, not upfront, and you receive the documents your insurer asks for: an engineer report and a VAT invoice. Many insurance policies include misfuelling cover, and so it's worth checking yours while we're on the way. ## About Green Hill, briefly Green Hill is a coastal suburban area in Aberdeenshire, situated near the North Sea at a low elevation of around 7 metres.
