Two fillers, two tanks: AdBlue in a diesel motor

Not one liquid but two: that is what many newer diesels near Stocks Bank and Snake Hill carry, with diesel feeding your motor. Kept in a tank of its own, AdBlue is sprayed into your exhaust gas to clean it.

There's a filler on every tank. Many of motors have a single flap for both, while others put the AdBlue filler to your boot or under the bonnet. At the petrol pump, the diesel side gets filled constantly. Someone who has to stop and work out where it goes usually tops up the AdBlue side, from a bottle, and much less commonly. That gap is where the slip lives.

How does AdBlue in your diesel tank take place around Stocks Bank?

Rarely is it carelessness: normally three things line up.

On a drive off Quarryside Road before work, or in the car park outside The Wasps Nest heading home: that is where the hurried top-up happens. Why the rush? As AdBlue runs low the vehicle warns you, and if it is empty, limp mode kicks in.

Then the vehicle is strange. A hire car, a new vehicle or a company car puts the fillers where your last one didn't, and your hand hits for the cap it would have used on the old one.

A spouted bottle finds no resistance at a diesel filler no more than at an AdBlue one. So the tip, once begun, carries on. The same few seconds settle it, in the middle of Stocks Bank or out in Nab.

Flushing a diesel fuel system after AdBlue, Stocks Bank

Which filler is for AdBlue, and which for diesel?

Check these first, on a forecourt around Stocks Bank or a drive over in Kitson Hill. Seconds, no more.

  • Read the cap instead of going by where it sits: AdBlue ones are frequently blue or marked "AdBlue", and diesel caps usually aren't.
  • Many vehicles fit AdBlue the smaller neck of the two.
  • The flap. Look inside the fuel flap for a label. Plenty of cars say there which fuel goes where.
  • The handbook shows which it lives if the filler isn't next to your diesel cap: your boot, or under the bonnet.
  • The person who drove the vehicle last. On a hire or company car collected from somewhere like the car park outside Mirfield, ask before you leave, not when the light comes on.

Topping up AdBlue without it reaching your diesel tank

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

  • Park then switch off. Not on a slope, not with the engine running, and not in a rush on the side of Nab Lane.
  • Daft as it sounds, saying "AdBlue" out loud as you unscrew the cap does the trick — once you have located your filler and read the cap.
  • Both under a single flap? So make sure the lid on the diesel filler is still closed ahead of lifting the bottle.
  • Finish once the tank fills or the bottle runs dry; before that, pour gently through its own spout.
  • Only then, start the vehicle: close the cap, check once more, and make sure your diesel cap was never opened.

Discover at the second or third stage that AdBlue went in the diesel filler? That's where you stop. Step five is out.

Already put AdBlue in the diesel tank around Stocks Bank?

Short list, then. First: the motor stays off. The fuel pump runs on plenty of diesels as soon as the ignition goes on — so leave it off. Filling up with diesel will not dilute it: instead, AdBlue sinks to the bottom of your tank, right where the fuel is taken from.

The attendants at Shell, Esso or another forecourt will normally lend a hand pushing your car away when you ask. Leave it where it is if you're on your own drive in Stocks Bank.

If the engine has already run, stop as soon as it is safe and switch off. The next exit is where to come off if you're on the M62, under 3 miles from Stocks Bank. Roughly how far did it go? Crossing Stocks Bank is smaller work than a trip of under 10 miles to Bradford, so say.

What happens when our technicians get there in Stocks Bank

Our van comes to the vehicle anywhere it stopped — your own driveway, beside Church of the Resurrection, or outside Battyeford CofE (VC) Primary School. What liquid was put in, the amount, and if it ran: our engineers ask because those replies decide the work and price. You hear that quote by phone, before anyone sets off.

Emptying the tank comes next, then a full flush of your system. Not like petrol, AdBlue leaves crystals and eats at certain fuel-system metals, and none of it clears away by itself. Hence it matters more. Your filter is flushed, or replaced where it needs to be; fresh diesel goes in; and the vehicle is tested. We don't leave until it has been started and is running properly.

If the motor hasn't run, most jobs take about half an hour once we're there, using pumps that are safe on a working forecourt and quiet enough to use outside a house at night. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Before we get there, have a look at your policy; plenty carry cover for misfuelling.
