AdBlue in a diesel vehicle: two tanks, two fillers

Not one fluid but two: that's what many newer diesels around Sibford Gower and Epwell carry, with diesel for your motor. AdBlue goes to your exhaust, where it is sprayed into the gas to clean it, and it lives in a tank of its own.

Each tank has a filler of its own. 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 goes in on each filling station visit, again and again. Much less frequently, the AdBlue side is topped up — mostly from a bottle, by someone thinking about where it goes. That gap is where the error lives.

How does AdBlue in your diesel tank take place in Sibford Gower?

Three things tend to come together, and carelessness is seldom one of them.

On a driveway off Main Street before work, or in the car park at The Wykham Arms on the way home: that is where the hurried top-up takes place. What is the reason for the rush? As AdBlue runs low the vehicle warns you, and if it is empty, limp mode follows.

Next, your hand reaches for the cap it would have used on the old car — since a rental car, a new vehicle or a company car puts the fillers where your last one did not.

A spout-topped bottle finds no obstacle at a diesel filler any more than at an AdBlue one. And so the pour, after started, keeps on. Whether it occurs in Burdrop or the middle of Sibford Gower, it is the same few seconds.

Flushing a diesel fuel system after AdBlue, Sibford Gower

Which filler is for AdBlue, and which for diesel?

Check these before pouring, on a forecourt in Sibford Gower or a driveway out in Winderton. A few seconds, no more.

  • Colour and marking: an AdBlue cap is regularly blue, or says "AdBlue", where a diesel cap normally does not. Trust the cap, not its position.
  • On plenty of cars, the size tells: AdBlue has the smaller filler neck.
  • The flap. Look inside your fuel flap for a label. Many vehicles say there which fuel goes where.
  • The handbook shows which it lives when your filler is not next to the diesel cap: the boot, or under the bonnet.
  • Collecting a hire or company car, perhaps at the car park at Banbury? Ask whoever drove it last before leaving, not once the light goes on.

AdBlue top-ups that never reach your diesel tank

The day the light comes on, wherever in Oxfordshire, follow this routine.

  • Stop on level, motor off, with time to spare — never hurried on the side of Colony Road.
  • Say "AdBlue" out loud as you unscrew the cap, after you find the AdBlue filler and read it. Silly, perhaps, yet it works.
  • The two under one flap? Then make sure the lid on your diesel side stays shut before raising the bottle.
  • Tip slowly, using the bottle's own spout. Stop when it's full or when the bottle is empty.
  • Shut the cap, then check once more — making sure your diesel cap remained shut the whole time. Only then, start the vehicle.

If at step two or three you find you have already poured into your diesel side, stop there. Step five stays out.

AdBlue in your diesel tank already, in Sibford Gower?

What follows is a short order of things, starting with no starting the engine. Leave the ignition off as well, since on plenty of diesels switching it on alone starts the pump. Diluting it with more diesel won't work, because AdBlue settles to the bottom rather than mixing — and that is where the fuel is drawn from.

Ask the staff to help roll your car away from the pump if you are at a forecourt — the The Forge Garage, the BP or anywhere else. Leave it where it is if you are on your own drive in Sibford Gower.

Where your motor has run already, stop safely and turn it off. The next junction means the place to leave if you are on the M40, under 10 miles from Sibford Gower. Mileage matters — a short hop across Sibford Gower makes a smaller job than driving under 25 miles towards Oxford — so tell us about how far it went.

Our arrival around Sibford Gower, and what happens next

Anywhere the vehicle came to rest, be it outside Sibford Gower Endowed Primary School, near Methodist Church or on your own drive, the van comes to it. Both the work and the quote depend on three replies — which liquid, what amount, and whether it has run — so our technicians ask. The quote comes on the call, before any van leaves.

Emptying that tank comes next, followed by a full flush of the fuel system. AdBlue crystallises and is corrosive to some of the metals in a fuel system, so it doesn't wash out on its own — which is why the flush matters more here than with petrol. Filter flushed or, where needed, swapped; clean diesel in; then a test of your car. Before we go, our technicians start it and check that it's running correctly.

With pumps fine on a working forecourt and quiet enough for use outside a house at night, most jobs in which the engine has not run need about half an hour once our technicians arrive. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Wrong-fuel cover is included in plenty of insurance policies — and so make use of the wait to look at yours.
