AdBlue in a Diesel Tank in Higher Wheelton: Why It Happens and How to Prevent It

Stop here a minute if your diesel tank already holds AdBlue in it: ignition off, motor off, and ring 0333 366 0103.

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

Diesel goes to the motor — but many modern diesels seen about Higher Wheelton and Brinscall hold a second liquid too. Kept in a tank of its own, AdBlue is sprayed into your exhaust gas and cleans it.

Every tank has one filler of its own. On a lot of cars the two sit side by side under the same flap; on others the AdBlue filler is in your boot or under the bonnet. Topping up the diesel side at the petrol pump happens all the time. Far less regularly, the AdBlue side gets filled — normally from a bottle, by a person thinking about where it goes. That gap is where the error lives.

Higher Wheelton: how AdBlue in your diesel tank occurs

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

The warning comes first. As AdBlue runs low the car tells you, and if it runs out completely, the vehicle goes into limp mode. So the top-up is done in a hurry: on a drive off Bett Lane before work, or in the car park outside Golden Lion on the way home.

Then, the hand goes for the cap it would have used on the old motor — since a hire car, a new car or a company car puts the fillers where your last one did not.

Lastly, the bottle goes in: diesel filler or AdBlue one, it slides in as easily, and after the tip starts, nothing stops it. Whether it takes place in Withnell Fold or the middle of Higher Wheelton, it's the same few seconds.

Telling the AdBlue filler from your diesel filler

Before you tip anything, whether on a driveway in Ollerton Fold or a forecourt in Higher Wheelton, check these. They take a few seconds.

  • Read the cap instead of going by where it sits: AdBlue caps are often blue or marked "AdBlue", and diesel ones normally aren't.
  • On many motors, size gives it away: AdBlue has the smaller filler neck.
  • Lift the flap and look for a label — many motors mark what goes in each filler right there.
  • The handbook. If the filler is not by your diesel cap, it is in the boot or under the bonnet, and the handbook says which.
  • Whoever had it before knows. Ask as you pick up a hire car or fleet car — from Pleasington's car park, perhaps — not once the light appears.

How to top up without AdBlue in the diesel tank

For the day the light comes on — wherever it is around Lancashire — a simple routine to use.

  • Turn off once parked — flat ground, motor stopped, and not rushed beside Jenny Lane at the roadside.
  • Say "AdBlue" out loud as you unscrew the cap, once finding the AdBlue filler and reading it. Silly, perhaps, but it works.
  • The two behind one flap? So confirm the lid on your diesel filler is still shut before raising the bottle.
  • Slowly does it, through the bottle's own spout, until it's full or the bottle runs out.
  • Before you start the vehicle, close the cap and check again that your diesel cap was never came off.

Stop there if you find, at stage two or three, that you've already poured into your diesel side. Step five stays off limits.

Already put AdBlue in your diesel tank in Higher Wheelton?

Then the order of things is short. Don't start your motor. Don't switch the ignition on; on plenty of diesels that alone runs the fuel pump. Do not top up with diesel to thin it: AdBlue doesn't mix with diesel, it sinks to the bottom of your tank, where the fuel is sucked from.

Ask the staff to help push your car away from the pump if you are on a forecourt — the D.Mayor & Son Coal Merchants, the Shell or somewhere else. Your own driveway in Higher Wheelton is where it stays.

Stop as soon as it is safe and switch off, if the engine has already run. The next junction is the place to come off if you're on the M65, under 3 miles from Higher Wheelton. Tell us about how far it went: a run towards Preston, under 10 miles away, is a bigger job than a short hop across Higher Wheelton.

Our arrival in Higher Wheelton, and what takes place next

By Withnell Fold Primary School, close to Withnell Fold Sports and Social Club or on your own drive: wherever the vehicle has stopped, we come to it. The replies settle this work and the quote, so we ask what was put in, about how much, and if it has run. No one sets off until you've heard our quote by phone.

Draining your tank comes next, followed by a full flush of your system. Not like petrol, AdBlue forms crystals and attacks some fuel-system metals, and none of that washes away unaided. Hence it counts more. The filter cleaned or, where needed, swapped; fresh diesel in; and then a check of your vehicle. We don't leave until it has been fired up and is running correctly.

Most jobs are finished in about half an hour after our engineers get there, provided your motor hasn't run — and the pumps we use are safe on a busy forecourt and quiet at night outside a house. Nothing upfront; you settle up on the day. Afterwards, the VAT invoice and a report from the engineer are handed to you for the insurer. While we travel, take a look at your insurance documents; plenty carry cover for misfuelling.
