Why does AdBlue in a diesel motor need its own filler?

Plenty of modern diesels on the roads about Aspull Common and Diggle Green carry two liquids, not one. Diesel goes to the motor. AdBlue's own tank keeps it, and from there it is sent to the exhaust, and there spraying cleans the gas.

Every tank comes with one filler of its own. Some cars keep the AdBlue filler in your boot or under the bonnet; a lot of others have both side by side under one flap. At the pump, your diesel side is topped up constantly. The AdBlue side is fuelled far less frequently, usually from a bottle, and normally by somebody who has to stop and think where it goes. The slip lives in that gap.

How does AdBlue in the diesel tank happen around Aspull Common?

It's hardly ever carelessness. Three things tend to line up.

The warning comes first. As AdBlue runs low the car tells you, and if it runs out completely, the vehicle drops into limp mode. So the top-up is done in a hurry: on a driveway off Leighton Drive before work, or in the car park outside Shepherd's Inn on the way home.

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

A spout-topped bottle meets no obstacle at a diesel filler no more than at an AdBlue one. So the pour, after started, carries on. Wash End or the heart of Aspull Common: it takes the same few seconds either way.

The AdBlue filler and the diesel filler: telling them apart

Be it a Aspull Common forecourt or a driveway out in Plank Lane, take a couple of seconds over these before anything goes in.

  • The cap. The AdBlue cap is frequently blue, or marked "AdBlue". The diesel cap usually isn't. Read it rather than going by position.
  • On many vehicles, the size tells: AdBlue gets the smaller filler neck.
  • A label inside the fuel flap often shows which fuel goes where, on plenty of cars. Look for it.
  • The handbook. If the filler is not by the diesel cap, it's in the boot or under the bonnet, and the handbook says which.
  • The previous driver will know. Ask when you pick up a rental or fleet car — from Newton-Le-Willows's car park, say — not once the light appears.

Keeping AdBlue out of the diesel tank when you top up

On the day the warning appears — anywhere you are around Greater Manchester — a routine to use.

  • Pull in somewhere level, engine off, with time to spare — never hurried on the side of Derwent Way.
  • Silly as it sounds, saying "AdBlue" out loud while you unscrew the cap does the trick — once you have found the filler and read the cap.
  • The two under a single flap? Then confirm the cap on your diesel side is still closed before lifting the bottle.
  • Stop when your tank is topped up or the bottle is empty; before that, tip slowly using its own spout.
  • Shut the cap, and look again — confirm your diesel cap remained shut throughout. Only then, start the vehicle.

Find at stage two or three that it has already gone into the diesel side? Then stop right there. Never carry on to stage five.

Aspull Common: already put AdBlue in the diesel tank?

Then the order of things is short. Do not start the engine. The fuel pump runs on many diesels as soon as the ignition is switched on — so keep it off. Do not top up with diesel to thin it: AdBlue does not mix with diesel, it sinks to the bottom of that tank, where your fuel is sucked from.

On a forecourt — Morrisons, Esso or another — the attendants will normally help roll your car clear, if you ask. If you are on your own driveway in Aspull Common, leave it where it is.

When the motor has run already, pull over safely then switch it off. Aspull Common lies under 3 miles from the M6; there, take the first junction. Distance counts — a quick hop across Aspull Common makes a smaller job than heading under 15 miles towards Salford — so tell us about how far it went.

Our arrival around Aspull Common, and what occurs next

Outside Gilded Hollins Community School, close to Lowton Independent Methodist Church or on your own drive: wherever your car has stopped, we come to it. Our engineers ask what was put in, roughly how much, and whether it's run, since the replies decide this work and the price. The price comes over the phone, ahead of any van leaving.

Then your tank is emptied and your system purged thoroughly. Not like petrol, AdBlue leaves crystals and attacks certain fuel-system metals, and neither clears away unaided. That is why it counts more. Testing comes at the end: before that, clean diesel is added, and the fuel filter is flushed or replaced if necessary. We don't go until it has been fired up and is running properly.

Most jobs are finished in about half an hour once our engineers get there, provided the motor has not run — and the pumps our engineers use are safe on a busy forecourt and quiet after dark beside a house. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. While we travel, take a look at your policy; plenty include cover for misfuelling.
