Two fillers, two tanks: AdBlue in a diesel vehicle

Not one liquid but two: that is how many newer diesels around Muirhead and Liff carry, with diesel feeding the engine. AdBlue's own tank keeps it, and from there it is sent to the exhaust, where spraying treats the fumes.

Each tank comes with one filler of its own. On a lot of vehicles the two sit side by side under the same flap; on others the AdBlue filler is in your boot or under the bonnet. Diesel gets filled on every forecourt call-out, again and again. Someone who has to stop and work out where it goes usually fills the AdBlue side, from a bottle, and much less often. That gap is where the slip lives.

AdBlue in the diesel tank around Muirhead: how it takes place

Three things tend to line up, and carelessness is rarely one of them.

Haste follows from the warning. The car warns you as AdBlue runs low, and a dry tank puts it into limp mode — so the top-up happens quickly, before work on a drive off Edward Place, or on the way home in the car park outside Birkhill Inn.

Next, your hand reaches for the cap it would have used on the old car — because a rental car, a new vehicle or a company car places the fillers where your last one didn't.

Lastly, the spout fits: diesel filler or AdBlue filler, it slides in just as easily, and once the pour starts, nothing halts it. The same few seconds decide it, in the middle of Muirhead or out in Backmuir of Liff.

The AdBlue filler and the diesel filler: telling them apart

Check these before pouring, at a forecourt in Muirhead or a drive out in Mains of Gray. Seconds, that's all.

  • Colour and lettering: an AdBlue cap is often blue, or says "AdBlue", where a diesel cap usually does not. Go by the cap, not its position.
  • On many cars, size tells: AdBlue has the smaller filler neck.
  • A label inside the fuel flap frequently shows which fuel goes where, on plenty of vehicles. Check for it.
  • The handbook shows where it is when your filler isn't next to your diesel cap: your boot, or under the bonnet.
  • Ask the person who drove it last — before you leave, not when the light comes on — when you pick up a hire or company car from somewhere like the car park outside Invergowrie.

How to top up without AdBlue in your diesel tank

A routine for the day the light comes on, wherever across Angus that is.

  • Not in a rush on the side of Liff Road, not on a slope, not with your engine running: park and switch off first.
  • Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds daft and it works.
  • Leave your diesel cap on. If both sit under one flap, check the diesel cap is still closed before you lift the bottle.
  • Stop once the tank fills or the bottle is empty; before that, pour slowly using the own spout.
  • Only then, start the vehicle: close the cap, check once more, and make sure your diesel cap was never opened.

Find at stage two or three that it's already gone into the diesel side? So stop just there. Step five stays off limits.

Muirhead: already put AdBlue in the diesel tank?

Brief list, then. First: your engine stays off. On many diesels the ignition alone runs the fuel pump, and so don't switch the vehicle on. AdBlue doesn't mix with diesel — it sinks to the bottom of your tank, where the fuel is sucked from — so don't top up with diesel to thin it.

Ask the attendants to help push the vehicle away from the pump if you are at a forecourt — the Asda Express, the Asda or somewhere else. At home around Muirhead? So the vehicle remains put.

Stop as soon as it is safe and switch off, if the motor has already run. Leave the M90 — under 15 miles out of Muirhead — at the next junction. A short hop across Muirhead is a smaller job than a run towards Dundee, under 5 miles away, so tell us roughly how far it went.

Muirhead: what occurs when we arrive

By the local primary school, close to Muirhead War Memorial or on your own driveway: wherever the car has stopped, we come to it. The replies determine the work and the price, and so our technicians ask what was put in, about how much, and whether it's run. Nobody heads out until you've heard our quote by phone.

After that: a drain, then a thorough flush of the whole system. Much more than with petrol, it matters here: the crystals form, some metals are attacked, and none of that clears out unaided, no matter how long it is left. After the fuel filter has been flushed — or replaced, if required — fresh diesel goes in, and finally your car is tested. Before we go, we fire it up and confirm that it is running correctly.

Unrun vehicles usually mean a half-hour visit from the moment we arrive. The equipment is safe on a live filling station, and quiet enough for a residential street after dark. The insurer usually wants the engineer's report and the VAT invoice, and both are yours at the end. Payment comes on the day, with no deposit. It is worth looking at your policy while we travel to you: misfuelling cover is included with many policies.
