Two fillers, two tanks: AdBlue in a diesel vehicle

Diesel goes to the motor — yet plenty of current diesels seen around Bilson Green and Double View carry a second fluid as well. Stored in a tank of its own, AdBlue is sprayed into your exhaust stream to clean it.

Different tanks, different fillers. Under one flap, next to each other: that's the arrangement on many motors. Elsewhere, AdBlue's filler sits under the bonnet or in your boot instead. Filling the diesel side at the pump happens constantly. Much less frequently, the AdBlue side is filled — normally from a bottle, by someone working out where it goes. It's in the gap that the slip lives.

Bilson Green: how AdBlue in your diesel tank happens

It is rarely carelessness. Three things tend to line up.

The warning comes first. As AdBlue runs low the vehicle tells you, and if it runs out altogether, the car drops into limp mode. So the top-up is done in a hurry: on a drive off Foxes Bridge Road before work, or in the car park outside Upper Bilson Inn on the way home.

Next, the hand goes for the cap it knew on the old motor — since a hire car, a new car or a company car places the fillers where your last one did not.

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 pour after it has started. The same few seconds decide it, in the middle of Bilson Green or out in Cinderford.

How to tell the AdBlue filler from the diesel one

Whether a Bilson Green forecourt or a driveway out in Littledean Hill, take a couple of seconds over these before anything is poured in.

  • Position can mislead; the cap doesn't. AdBlue caps tend to be blue or carry the name "AdBlue" — diesel caps usually don't.
  • Plenty of motors give AdBlue the smaller neck of the two.
  • A label inside your fuel flap often shows which fuel goes where, on many cars. Look for it.
  • The handbook. If the filler isn't by your diesel cap, it is in the boot or under the bonnet, and the handbook says which.
  • Ask the person who drove it last — before you leave, not when the light comes on — if you pick up a hire or company car from somewhere like the car park outside Lydney.

How to top up without AdBlue in your diesel tank

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

  • Park then switch off. Not on a slope, not with the motor running, and not in a rush on the side of Forest Vale Road.
  • Find the AdBlue filler, read the cap, and speak the word "AdBlue" aloud as you unscrew it. It seems silly. It does the trick.
  • The two behind one flap? So confirm the cap on the diesel filler is still shut before raising the bottle.
  • Using the bottle's own spout, pour slowly — and stop when it is full or the bottle is empty.
  • Close the cap and check a second time. Make sure the diesel cap was never opened. Only then start the car.

Discover during the second or third stage that the bottle went into the wrong filler? That's where you stop. Don't go on to step five.

AdBlue in the diesel tank already, around Bilson Green?

The short order of things, starting with not starting the motor. On many diesels your ignition alone runs the fuel pump, so do not switch it on. AdBlue doesn't mix with diesel — it sinks to the bottom of that tank, where the fuel is pulled from — so don't top up with diesel to thin it.

The staff at Shire Fuels, Gulf or another forecourt will normally lend a hand pushing your car away when asked. Your own driveway around Bilson Green is the place it should stay.

When your engine has been run by now, pull over somewhere safe then turn the vehicle off. The next junction is the place to leave if you are on the M50, under 10 miles from Bilson Green. Tell us roughly how far it went: a run towards Gloucester, under 15 miles away, is a bigger job than a short hop across Bilson Green.

What happens when our technicians get there around Bilson Green

Our van reaches your car anywhere it has come to rest — your own drive, near Forest Community Church, or outside St White's Primary School. Those replies determine this work and our quote, so our technicians ask what got in, roughly how much, and whether it has run. You hear that quote on the phone, before anybody sets off.

After that: draining, then a thorough flush of the whole system. More than with petrol, it matters here: the crystals build up, certain metals are attacked, and none of that clears away on its own, however long it sits. The filter is cleaned, or replaced where it needs to be; fresh diesel goes in; and the vehicle is tested. We do not leave until it has been fired up and is running properly.

If your engine has not run, most jobs take about half an hour once we're there, using pumps that are fine on a working forecourt and quiet enough to use outside a house after dark. Your insurer usually wants an engineer's report and the VAT invoice, and both are yours at the end. Payment is on the day, with no deposit. It is worth looking at your policy while we travel to you: misfuelling cover comes with many policies.

Bilson Green and Gloucestershire: AdBlue drains across the area

The car remains put. Our engineers drain it where it is — a side street near CANDI Unlimites, a lay-by on the way to Cinderford Community Gardening Project, a drive. Assuming doesn't help behind Cinderford Baptist Church, close to a boundary, or somewhere hard to describe; phone and check.
