--- title: AdBlue in a Diesel Tank Morefield? Read This canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/morefield-highland/ location: Morefield county: Highland latitude: 57.905850 longitude: -5.162010 service: AdBlue in a Diesel Tank updated: 2026-10-14 --- # Avoiding AdBlue in a Diesel Tank in Morefield: Why It Occurs Keep your motor and ignition off then ring 0333 366 0103 first — reading can wait if AdBlue is already in your diesel tank. Caught before your engine runs, it is generally a drain and a thorough flush, done where the vehicle is in Morefield. The rest of this page covers why it happens and how to ensure it does not — useful if you are reading ahead of time. ## AdBlue in a diesel vehicle: two tanks, two fillers Not one liquid but two: that is how plenty of newer diesels around Morefield and Ardmair carry, with diesel for your motor. Kept in a tank of its own, AdBlue is sprayed into the exhaust stream and cleans it. Every tank has a filler of its own. Other cars keep the AdBlue filler in the boot or under the bonnet; plenty more have both together behind one flap. The diesel side is topped up at the petrol pump all the time. Much less regularly, the AdBlue side gets topped up — mostly from a bottle, by a person working out where it goes. It's in that gap that the slip happens. ## AdBlue in the diesel tank in Morefield: how it happens It is hardly ever carelessness. Three things tend to line up. To start with, the warning. Low AdBlue brings a warning from your car, and running dry leads to limp mode — so a hurried top-up, maybe before work off Vyner Place, perhaps outside The Caley Inn on the way home after work. Then the vehicle is unfamiliar. A hire car, a new car or a company car puts the fillers where your last one didn't, and your hand gets to for the cap it would have used on the old one. And the bottle fits. A bottle with a spout goes into a diesel filler as easily as an AdBlue one, and so nothing stops the tip after it has started. Whether it occurs in Ullapool or the middle of Morefield, it is the same few seconds. ## Telling the AdBlue filler from your diesel filler Check these first, at a forecourt around Morefield or a driveway out in Blarnalearoch. A few seconds, no more. - Read the cap rather than going by position: AdBlue ones are regularly blue or marked "AdBlue", and diesel ones normally are not. - The size. On many motors the AdBlue filler neck is the smaller of the two. - A label inside your fuel flap frequently says which fuel goes where, on plenty of motors. Check for it. - The handbook shows which it lives when your filler is not next to your diesel cap: your boot, or under the bonnet. - Whoever had it before knows. Check when you collect a hire car or company car — at the nearest station's car park, say — rather than once the light appears. ## AdBlue top-ups that never reach your diesel tank For the day the light appears — anywhere it is around Highland — a routine to follow. - Park and switch off. Not on a slope, not with your engine running, and not in a rush on the side of North Road. - Daft as it sounds, saying "AdBlue" aloud as you unscrew the cap works — once you have located the filler and read the cap. - Both behind a single flap? Then make sure the cap on your diesel filler is still shut before lifting the bottle. - Using the bottle's own spout, tip slowly — and stop when it's full or the bottle is empty. - Close the cap and check once more. Make sure the diesel cap was never opened. Only then start the vehicle. Find at stage two or three that it's already gone into your diesel side? Then stop right there. Step five stays out. ## Already put AdBlue in the diesel tank in Morefield? Do not start your engine: that's where the short order of things starts. Keep your ignition off too, since on plenty of diesels switching it on by itself starts the pump. Thinning it with extra diesel fails, since AdBlue sinks to the base rather than mixing — and that is where the fuel is pulled from. On a forecourt — JET, another forecourt nearby or another — the staff will usually help push your car away, if you ask. If you are on your own drive around Morefield, leave the car where it sits. If the motor has already run, stop as soon as it is safe and switch off. Leave the M90 — over 50 miles out of Morefield — at the next exit. Tell us about how far it went: a run towards Inverness, under 50 miles away, is a bigger job than a short hop across Morefield. ## Our arrival in Morefield, and what happens next Our van reaches your car anywhere it stopped — your own drive, beside Lochbroom Leisure Centre, or by the local primary school. We ask what got in, about how much, and whether it's run, because the replies determine the work and the price. That price is given on the call, ahead of any van leaving. Then your tank is emptied and your system flushed thoroughly. Unlike petrol, AdBlue forms crystals and eats at certain fuel-system metals, and none of it clears away unaided. Hence it counts more. After your filter is flushed — or replaced, where needed — clean diesel goes in, and finally the car is tested. Before we go, our technicians start it and make sure that it is running properly. Most jobs are finished in about half an hour once our engineers get there, as long as the motor hasn't run — and the pumps our engineers use are safe on a live forecourt yet quiet after dark outside a house. Your insurer will ask for the engineer's report and your VAT invoice, and both are yours at the end. Payment comes on the day, with no money upfront. It is worth checking your insurance while we travel to you: misfuelling cover comes with many policies. ## About Morefield and where it is Morefield is a small suburban area situated on the coast of Highland, Scotland, with an elevation of 23 metres. Morefield lies near Ullapool and the Braes of Ullapool, and is also close to Rhue. Morefield has a population of around 504 people and predominantly features semi-detached housing. ## AdBlue drains around Morefield, and Highland beyond As a residential suburb, Morefield has the same vans as surrounding places — Braes of Ullapool, Rhue — right through IV postcodes and the wider area around them. Give a postcode that starts IV26 2, and the van gets there fastest. The vehicle does not need to shift. A driveway, a lay-by on the way to Ullapool Golf Club, a side street near Ullapool Village Hall: we drain the vehicle where it is. Awkward to pin down, like the back of Church of Scotland? By a county line? Checking beats guessing, and so ring. ## The short version for Morefield motorists Read the cap before you tip. AdBlue in your diesel tank regardless?
