AdBlue in a diesel car: two tanks, two fillers

Plenty of newer diesels on the roads round Mill Yard and Sandfield Park carry two liquids, not one. Diesel goes to your engine. Kept in a tank of its own, AdBlue is fed into the exhaust gas to clean it.

Separate tanks, separate fillers. On a lot of motors the two sit side by side under the same flap; on others the AdBlue filler is in the boot or under the bonnet. Diesel gets filled on every filling station call-out, again and again. Rarely filled, AdBlue usually comes out of a bottle, tipped by someone who must stop and think what filler to use. That gap is where the error lives.

How AdBlue in the diesel tank happens around Mill Yard

Carelessness rarely explains it. Instead is three things coming up at once.

Haste follows from the warning. The car tells you as AdBlue runs low, and a dry tank sends it into limp mode — so the top-up gets done quickly, before work on a drive off The Lynxway, or on the way home in the car park outside The Wheatsheaf.

The old car's filler is where your hand goes — but a hire car, a new motor or a company car puts the fillers somewhere else. That's a second thing: a strange car.

A spouted bottle meets no obstacle at a diesel filler no more than at an AdBlue one. And so the pour, after started, keeps on. Knotty Ash or the middle of Mill Yard: it takes the same few seconds in both.

Flushing a diesel fuel system after AdBlue, Mill Yard

Telling the AdBlue filler from the diesel filler

A few seconds is all these take — so check them before you pour anything, on a drive in Broad Green or a forecourt in Mill Yard.

  • Where it sits can mislead; the cap doesn't. AdBlue ones tend to be blue or carry the name "AdBlue" — diesel caps usually do not.
  • The size. On many motors the AdBlue filler neck is the smaller of the two.
  • Check inside the fuel flap: many cars have a label there saying which fuel goes where.
  • The handbook says which it lives if your filler isn't next to your diesel cap: your boot, or under the bonnet.
  • Whoever had it before knows. Check as you collect a hire car or company car — at Broad Green's car park, perhaps — not when the light appears.

Topping up AdBlue without it reaching your diesel tank

Wherever in Merseyside the light comes on, here is a routine for the day.

  • Turn off once parked — flat ground, motor off, and not in a rush beside The Bryceway on the verge.
  • Find the AdBlue filler, read the cap, and speak the name "AdBlue" out loud while unscrewing it. It sounds daft. It does the trick.
  • If both sit under one flap, check your diesel cap is still closed before you lift the bottle — then leave it on.
  • Pour slowly, using the bottle's own spout. Stop when it's full or when the bottle is empty.
  • Only after that, start your car: close the cap, check once more, and make sure the diesel cap was never opened.

Find at step two or three that it's already gone into your diesel side? So stop just there. Leave out step five altogether.

Mill Yard: already put AdBlue in your diesel tank?

Brief order, then. Top of it: the motor stays off. Don't switch the ignition on; on many diesels that alone runs the fuel pump. Topping up with diesel will not weaken it: rather than mixing, AdBlue sinks to the base of your tank, just where fuel is drawn from.

The staff at Sainsbury's, Esso or another forecourt will usually help to push the vehicle away when you ask. Leave it where it is if you're on your own driveway in Mill Yard.

Where the engine has been run already, stop safely then turn the vehicle off. The next junction is where to come off if you're on the M62, under a mile from Mill Yard. Roughly how far did it go? Crossing Mill Yard is smaller a job than a run of under 5 miles towards Liverpool, so tell us.

Mill Yard: what happens when our engineers get there

Outside Knotty Ash Primary School, close to Cavalry Church or on your own drive: wherever your car has stopped, our technicians come to it. Our engineers ask what got in, roughly how much, and whether it's run, because the replies decide this work and the quote. The price comes on the call, ahead of any van leaving.

The system is then flushed thoroughly, after that tank is cleared. Unlike petrol, AdBlue leaves crystals and eats at certain fuel-system metals, and none of that clears away unaided. That is why it counts more. Filter cleaned or, where it must be, replaced; clean diesel in; and then a test of the car. The engine is fired up next and checked to be sure it runs correctly, all before our engineers leave.

Using pumps fine on a working forecourt and quiet enough for use outside a house at night, most jobs in which the engine hasn't run need roughly half an hour once we arrive. Nothing upfront; you settle up on the day. At the end, the VAT invoice and the report from the engineer go to you for the insurer. While we travel, take a look at your policy; many carry cover for misfuelling.

No need to move the car. Our engineers drain it where it is — a side street near Dovecot Community Centre, a lay-by on the way to Dovecot Park, a driveway. Tricky to pin down, like the back of Dovecot Evangelical Church? Close to a county line? Checking is better than assuming, so ring.
