AdBlue in a diesel motor: two tanks, two fillers

Plenty of current diesels on the roads about Higher Blackley and Rhodes Green carry two liquids, not one. Diesel goes to your engine. AdBlue goes to your exhaust, where it is sprayed into the gas to fresh it, and it lives in a tank of its own.

Each tank has its own filler. On a lot of motors the two sit side by side under the same flap; on others the AdBlue filler is in your boot or under the bonnet. Diesel gets filled on each filling station visit, again and again. The AdBlue side is filled far less often, normally from a bottle, and normally by someone who has to stop and think where it goes. Mistakes happen in that gap between the two.

How does AdBlue in your diesel tank occur in Higher Blackley?

Seldom is it carelessness: usually three things coincide.

Hurry comes from the warning. The vehicle warns you as AdBlue runs low, and a dry tank sends it into limp mode — so the top-up gets done in a rush, before work on a driveway off Wavertree Road, or on the way home in the car park at The Flying Horse.

The old car's cap is where your hand reaches — yet a rental car, a new motor or a company car puts the fillers somewhere else. That is the second factor: a strange motor.

No part stops the pour once it has started, since a bottle with a spout goes into a diesel filler as easily as an AdBlue one. The bottle fits. It takes a few seconds, whether in Rhodes or bang in the heart of Higher Blackley.

How to tell the AdBlue filler from the diesel one

Before you pour anything, whether on a drive in Lime Field or a forecourt around Higher Blackley, check these. They take a couple of seconds.

  • Colour and marking: an AdBlue cap is commonly blue, or says "AdBlue", where a diesel cap usually does not. Trust the cap, not where it sits.
  • The size. On plenty of motors the AdBlue filler neck is the smaller of the two.
  • A label inside your fuel flap frequently says which fuel goes where, on plenty of vehicles. Check for it.
  • In the boot or under the bonnet: that's where the filler is if it's not by the diesel cap, and the handbook says which.
  • The previous driver knows. Ask when you pick up a hire car or company car — from Moston's car park, perhaps — rather than once the warning appears.

Topping up AdBlue without it reaching your diesel tank

Wherever in Greater Manchester the light comes on, this is a routine for that day.

  • Not in a rush on the side of Longhurst Road, not on a slope, not with your motor running: park and switch off properly.
  • Say "AdBlue" out loud as you unscrew the cap, after finding the AdBlue filler and read it. Daft, perhaps, but it works.
  • If both sit under one flap, check your diesel cap is still closed before you lift the bottle — and leave the vehicle on.
  • Using the bottle's own spout, pour slowly — and stop when it is full or the bottle is empty.
  • Close the cap, then look again — confirm your diesel filler remained shut the whole time. After that, start your car.

If at stage two or three you find you have already poured into your diesel side, stop there. Don't carry on to step five.

AdBlue in your diesel tank already, in Higher Blackley?

Brief order, then. First: the motor remains off. Don't switch the ignition on; on plenty of diesels that alone runs the fuel pump. AdBlue doesn't mix with diesel — it sinks to the bottom of the tank, where the fuel is sucked from — so don't top up with diesel to thin it.

Ask the staff to help push your car clear of the petrol pump if you're on a forecourt — the the nearest petrol station, the Sainsbury's or anywhere else. On your own drive around Higher Blackley? So your car stays put.

When the motor has been run by now, pull over safely then turn the car off. Come off the M60 — under a mile out of Higher Blackley — at the first junction. Mileage counts — a quick hop across Higher Blackley is a smaller job than heading under 5 miles towards Manchester — so say about how far it went.

What takes place when our engineers get there around Higher Blackley

Wherever the car came to rest, whether by Crab Lane Primary School, beside St Andrew's or on your own drive, our van comes to it. We ask what got in, roughly how much, and if it's run, because those replies determine the work and the price. During the call itself, you hear our quote — before anything else.

The system is then cleaned thoroughly, after the tank is emptied. Unlike petrol, AdBlue forms crystals and attacks some fuel-system metals, and none of that clears away unaided. That is why it matters more. The filter flushed or, where needed, swapped; fresh diesel in; and then a test of your car. Before we go, we start it and make sure that it is running properly.

Unstarted vehicles usually mean a half-hour job after arrival. The equipment is fine on a live filling station, and hushed enough for a driveway late at night. The insurer will ask for the engineer's report and your VAT invoice, and both are yours at the end. Payment is on the day, with no money upfront. Many insurance policies include misfuelling cover, so it's worth checking yours while we're on the way.
