AdBlue in a diesel motor, and its separate tank

Diesel feeds the motor — but many current diesels driven about Hall Green and Elmers Green carry a second fluid too. Your exhaust, not the motor, is where AdBlue goes: dosed into the gas to fresh them, from a separate tank.

Different tanks, separate fillers. Some vehicles put the AdBlue filler in your boot or under the bonnet; plenty more have the two together under one flap. Diesel gets filled on each forecourt visit, again and again. Far less frequently, the AdBlue side is filled — mostly from a bottle, by someone thinking about where it goes. Mistakes happen in that gap between them.

Hall Green: how AdBlue in your diesel tank occurs

Carelessness seldom causes it. What does is three things coming up together.

The warning comes first. As AdBlue runs low the car 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 driveway off Dearden Way before work, or in the car park at The Victoria Hotel on the way home.

Unfamiliar vehicles come next, too. Rentals, new motors and company cars place their fillers differently, and habit reaches for the cap used on the old one.

A spout-topped bottle meets no resistance at a diesel filler no more than at an AdBlue one. So the tip, once started, keeps on. Up Holland or the heart of Hall Green: it takes the same few seconds either way.

The AdBlue filler and your diesel filler: telling them apart

Look at these before pouring, at a forecourt in Hall Green or a driveway out in Tanhouse. A few seconds, that's all.

  • Where it sits misleads; the cap doesn't. AdBlue ones tend to be blue or bear the word "AdBlue" — diesel ones normally do not.
  • Check the size: the smaller neck is, on many cars, the AdBlue one.
  • Open the flap and look for a label — plenty of cars mark what belongs in which inlet just there.
  • The handbook. If your filler isn't by the diesel cap, it is in your boot or under the bonnet, and the handbook says which.
  • Picking up a hire or company car, perhaps at the car park outside Upholland? Ask whoever drove it last before leaving, not when the light comes on.

Keeping AdBlue out of the diesel tank when you top up

Wherever in Lancashire the light comes on, here is a routine for that day.

  • Turn off after you park — level ground, engine stopped, and never in a rush by Delamere Way at the roadside.
  • Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds silly and it works.
  • Both under one flap? So make sure the lid on the diesel side stays closed before raising the bottle.
  • Tip slowly, using the bottle's own spout. Stop when it is full or when the bottle is empty.
  • Before you start the vehicle, close the cap and look again that the diesel cap never opened off.

Spot at step two or three that it has already gone into your diesel side? Then stop right there. Don't go on to step five.

Put AdBlue in the diesel tank in Hall Green already?

What follows is a short order of things, beginning with no starting the engine. The fuel pump runs on many diesels the moment your ignition is switched on — so keep it off. Filling up with diesel won't dilute it: instead, AdBlue sinks to the bottom of the tank, right where the fuel is taken from.

If you are on a forecourt, whether it's the Texaco or the Esso, ask the staff to help roll the vehicle clear of the pump. If you are on your own drive in Hall Green, leave the car where it stands.

Already started? Stop once it is safe, then switch off. Leave the M58 — under a mile out of Hall Green — at the first junction. Distance matters — a short hop across Hall Green is a smaller job than heading under 15 miles towards Liverpool — so say about how far it went.

Our arrival in Hall Green, and what takes place next

Outside St Thomas the Martyr Voluntary Aided Church of England Primary School, near Artz Centre or on your own drive: wherever your car has stopped, our technicians come to it. Both the work and our quote rest on three replies — which liquid, which quantity, and if it's run — so our engineers ask. That quote is given on the call, before any van leaves.

After that: a drain, then a thorough flush of the entire 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 that counts more here than with petrol. A test comes last: before that, fresh diesel is added, and your filter is cleaned or replaced if necessary. We don't leave until it has been fired up and is running smoothly.

Most jobs are finished in roughly half an hour once our technicians get there, provided the engine has not run — and the pumps our engineers use are fine on a busy forecourt yet quiet after dark outside a house. Your insurer will ask for an engineer's report and the VAT invoice, and you get both at the end. Payment comes on the day, with no money upfront. It's worth looking at your policy while we travel to you: misfuelling cover is included with plenty of policies.

The vehicle doesn't need to shift. Wherever it sits — beside Upholland Methodist Church, on a lay-by en route to Beacon Country Park, on a drive — that is where it gets emptied. Assuming won't help at the back of Upholland War Memorial, close to a boundary, or somewhere awkward to describe; phone and ask.

Hall Green motorists: the short version

Tip no AdBlue until you have read the cap. Petrol in Diesel drains it on the spot, anywhere in Lancashire, if AdBlue has gone in your diesel tank all the same — so leave the car off then call 0333 366 0103.
