Two fillers, two tanks: AdBlue in a diesel car

Plenty of modern diesels around Brookfield, like those in Ribbleton Hall, carry on two fluids; the engine gets just your diesel. AdBlue goes to the exhaust, where it is sprayed into the gas to clean it, and it lives in a tank of its own.

Different tanks, different fillers. Plenty of motors have a single flap for both, while some move the AdBlue filler to your boot or under the bonnet. Filling your diesel side at the pump happens all the time. Much less often, the AdBlue side gets filled — normally from a bottle, by a person working out where it goes. That gap is where the error lives.

AdBlue in your diesel tank in Ribbleton Hall: how it occurs

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

On a drive off Pope Lane before work, or in the car park outside Ribble Lodge on the way home: that's where the hurried top-up takes place. What is the reason for the rush? As AdBlue gets low the vehicle tells you, and if it is empty, limp mode kicks in.

Then your car is unfamiliar. A hire car, a new vehicle or a company car puts the fillers where your last one did not, and the hand gets to for the cap it would have used on the old one.

Lastly, the bottle goes in: a diesel filler or AdBlue filler, it slides in just as readily, and after the pour starts, nothing halts it. The same few seconds settle it, in the middle of Ribbleton Hall or out in Farringdon Park.

Flushing a diesel fuel system after AdBlue, Ribbleton Hall

Telling the AdBlue filler from your diesel filler

A couple of seconds is all these take — so check them before you tip anything, on a drive in Red Scar or a forecourt around Ribbleton Hall.

  • Blue and lettering: an AdBlue cap is often blue, or says "AdBlue", where a diesel cap usually doesn't. Go by the cap, not where it sits.
  • The size. On many motors the AdBlue filler neck is the smaller of the two.
  • A label inside the fuel flap frequently says which fuel goes where, on many cars. Check for it.
  • Can't find it next to the diesel filler? Then look beneath the bonnet or in your boot — the handbook says which.
  • The previous driver knows. Check when you pick up a rental or fleet car — at Preston's car park, perhaps — not once the light appears.

AdBlue top-ups that never reach the diesel tank

A routine for the day the light comes on, wherever in Lancashire that is.

  • Turn off after you park — flat ground, motor stopped, and never rushed beside Ribbleton Hall Drive on the verge.
  • Locate the AdBlue filler, read the cap, and speak the word "AdBlue" aloud as unscrewing it. It seems daft. It does the trick.
  • The diesel cap remains on. When both share a flap, make sure it is closed before lifting the bottle.
  • Gently does it, through the bottle's own spout, until it is full or 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.

If at step two or three you find you have already poured into the diesel side, stop there. Do not go on to step five.

Put AdBlue in your diesel tank in Ribbleton Hall already?

What follows is a short order of things, beginning with not starting your engine. The fuel pump starts on many diesels as soon as the ignition is switched on — so keep it off. Diluting it with more diesel won't work, because AdBlue sinks to the bottom rather than mixing — and that is where your fuel is pulled from.

Ask the staff to help roll your car away from the pump if you are on a forecourt — the Shell, the BP or somewhere else. If you are on your own drive around Ribbleton Hall, leave the vehicle where it sits.

Already run? Stop when it is safe, then switch off. The next junction is the place to come off if you are on the Preston Bypass, under a mile from Ribbleton Hall. Roughly how far did it go? Crossing Ribbleton Hall is less work than a run of under 3 miles to Preston, and so tell us.

Our arrival around Ribbleton Hall, and what occurs next

By Moor Nook Community Primary School, near Blessed Sacrament or on your own driveway: wherever the vehicle has stopped, our technicians come to it. Our engineers ask what was put in, roughly how much, and if it's run, because those replies decide the work and our price. You get that quote by phone, before anyone heads out.

Then the tank is cleared and the fuel system cleaned thoroughly. More than with petrol, it counts with AdBlue: crystals build up, some metals corrode, and none of it clears away unaided, no matter how long it sits. Once the filter is cleaned — or renewed, if required — clean diesel is added, and then your vehicle is tested. After that our engineers fire it up and make sure it runs smoothly before leaving.

With pumps safe on a busy forecourt and quiet enough for use outside a house at night, most jobs in which your motor has not run take roughly half an hour after we are there. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. While we travel, have a look at your insurance documents; many carry cover for misfuelling.
