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

Diesel goes to your engine — but many newer diesels driven about Misterton and West Stockwith hold a second liquid too. The exhaust, not the engine, is where AdBlue ends up: sprayed into the fumes to fresh it, from a separate tank.

Separate tanks, separate fillers. Plenty of vehicles share a single flap for both, whereas others move the AdBlue filler to the boot or under the bonnet. Diesel goes in at every filling station call-out, week in, week out. Rarely filled, AdBlue usually goes in out of a bottle, tipped by a driver who has to stop and think what cap to use. The slip lives in that gap.

AdBlue in the diesel tank in Misterton: how it occurs

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

On a driveway off Station Street before work, or in the car park outside Red Hart on the way home: that is where the hurried top-up happens. Why the rush? As AdBlue gets low the car tells you, and once it's gone, limp mode follows.

New-to-you motors come next, as well. Rentals, new cars and company cars put their fillers differently, and the hand goes for the cap used on the old one.

No part halts the pour after it has started, because a bottle with a spout goes into a diesel filler as readily as an AdBlue one. The bottle fits. Misterton Soss or the heart of Misterton: it takes the same few seconds in both.

Flushing a diesel fuel system after AdBlue, Misterton

Which filler is for AdBlue, and which for diesel?

Look at these first, on a forecourt in Misterton or a driveway out in Walkerith. Seconds, that's all.

  • Read the cap rather than going by position: AdBlue caps are commonly blue or marked "AdBlue", and diesel caps normally are not.
  • The size. On many cars the AdBlue filler neck is the smaller of the two.
  • A label inside your fuel flap frequently shows which fuel goes where, on many vehicles. Check for it.
  • Cannot find it beside the diesel filler? Then look below the bonnet or inside the boot — the owner's manual says which.
  • The person who drove the vehicle last. On a hire or company car picked up from somewhere like the car park at Gainsborough Central, ask before you leave, not when the light comes on.

Keeping AdBlue out of the diesel tank when you top up

A routine for the day the light comes on, wherever around Nottinghamshire that is.

  • Pull in on level, engine off, with time to spare — never hurried on the side of Wharf Road.
  • Silly as it sounds, saying "AdBlue" out loud as you unscrew the cap does the trick — after you have found the filler and read it.
  • The diesel cap stays on. Where both sit under a flap, make sure it's closed before the bottle comes up.
  • Using the bottle's own spout, tip slowly — and stop when it's full or the bottle is empty.
  • Close the cap, then look once more — making sure your diesel filler remained closed the whole time. After that, start the car.

If at stage two or three you find you have already poured into the diesel side, stop there. Skip step five altogether.

Already put AdBlue in the diesel tank around Misterton?

Short order, then. Top of it: your engine stays unstarted. The fuel pump runs on plenty of diesels the moment your ignition is switched on — and so leave it off. Do not top up with diesel to dilute it: AdBlue does not mix with diesel, it sinks to the bottom of your tank, where the fuel is pulled from.

The staff at Tesco, JET or any forecourt will usually help to push the car away if you ask. At home in Misterton? So the car remains where it is.

Already run? Pull over once it is safe, then switch off. Come off the M180 — under 10 miles out of Misterton — at the first junction. Tell us roughly how far it went: a run towards Doncaster, under 15 miles away, is a bigger job than a short hop across Misterton.

When our technicians arrive around Misterton, what occurs?

We come to your car wherever it has stopped, whether that's outside Misterton Primary and Nursery School, near All Saints or on your own driveway. The answers decide this work and the price, and so our engineers ask what went in, about how much, and if it has run. You get that quote on the phone, before anyone heads out.

Next: draining, then a full flush of the whole 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 counts more with AdBlue than with petrol. Once the fuel filter is flushed — or replaced, if needed — clean diesel is added, and finally the vehicle is tested. The engine is started next and tested to be sure it runs correctly, all before our engineers go.

Most jobs are finished in roughly half an hour once our engineers get there, as long as your motor hasn't run — and the pumps our technicians use are safe on a live forecourt and quiet at night outside a house. Nothing upfront; you settle up on the day. Afterwards, a VAT invoice and a report from the engineer are handed to you for the insurer. Many insurance policies include misfuelling cover, and so it's worth checking yours while we're on the way.
