Why It Occurs and How to Prevent It: AdBlue in a Diesel Tank in Upper Moor Side

Stop here a minute when your diesel tank already has AdBlue in it: ignition off, engine off, and phone 0333 366 0103. Caught before the motor runs, it is normally a drain and a thorough flush, done where the vehicle is around Upper Moor Side. If you're reading before it has happened, the remainder of this page is about why it occurs and how to make sure it does not.

AdBlue in a diesel motor: two tanks, two fillers

Many newer diesels on the roads around Upper Moor Side and Low Moor Side carry two liquids, not one. Diesel goes to your motor. AdBlue goes to your exhaust, where it is sprayed into the gas to clean it, and it lives in a tank of its own.

Separate tanks, separate fillers. Other cars keep the AdBlue filler in your boot or under the bonnet; plenty of others have both side by side under one flap. Diesel goes in on every filling station call-out, week in, week out. The AdBlue side is filled far less often, normally from a bottle, and usually by a person who has to stop and think where it goes. It's in the gap that the slip happens.

Upper Moor Side: how AdBlue in your diesel tank occurs

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

Haste follows from the warning. The car tells you as AdBlue runs low, and an empty tank puts the vehicle into limp mode — so the top-up happens in a rush, before work on a driveway off Gildersome Lane, or heading home in the car park outside The Woodcock.

The old car's filler is where the hand goes — but a hire car, a new car or a company car puts the fillers elsewhere. That's the second thing: an unfamiliar car.

And the bottle fits. A bottle with a spout goes into a diesel filler as easily as an AdBlue one, so nothing stops the pour after it has started. It takes seconds, whether in Moor Head or right in the centre of Upper Moor Side.

Flushing a diesel fuel system after AdBlue, Upper Moor Side

Telling the AdBlue filler from the diesel filler

Look at these before pouring, at a forecourt around Upper Moor Side or a drive out in Gildersome. Seconds, no more.

  • Where it sits misleads; the cap does not. AdBlue ones are often blue or carry the name "AdBlue" — diesel caps normally do not.
  • On many motors, the size tells: AdBlue gets the smaller filler neck.
  • Look inside your fuel flap: many vehicles carry a label there showing which fuel goes where.
  • The handbook. If the filler isn't by the diesel cap, it is in the boot or under the bonnet, and the handbook says which.
  • Picking up a hire or company car, say at the car park at Cottingley? Check with whoever drove the car last before leaving, rather than once the light goes on.

Keeping AdBlue out of the diesel tank when you top up

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

  • Stop on level, motor off, with time to spare — never hurried on the side of Back Lane.
  • Say "AdBlue" out loud as you unscrew the cap, once finding the AdBlue filler and reading it. Daft, yes, but it does the trick.
  • The diesel cap stays on. When the two share a flap, confirm it is closed before lifting the bottle.
  • Stop once your tank is topped up or the bottle runs dry; until then, pour gently through the built-in spout.
  • Only then, start the vehicle: close the cap, check once more, and make sure the diesel cap was never opened.

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

Put AdBlue in the diesel tank in Upper Moor Side already?

What follows is a short order of things, beginning with no starting your engine. Don't switch your ignition on; on plenty of diesels that alone runs the fuel pump. AdBlue does not mix with diesel — it sinks to the bottom of that tank, where your fuel is sucked from — so don't top up with diesel to thin it.

The staff at Esso, another forecourt nearby or any forecourt will usually lend a hand pushing the vehicle away when asked. Your own driveway in Upper Moor Side is where it stays.

If your engine has already run, stop as soon as it is safe then switch off. On the M621, under 3 miles from Upper Moor Side, that means the next junction. Roughly how far did it go? Crossing Upper Moor Side is smaller work than a trip of under 5 miles to Leeds, and so say.

Upper Moor Side: what takes place when our engineers arrive

We come to the vehicle wherever it has stopped, whether that is outside Gildersome Primary School, near Gildersome Baptist Church or on your own driveway. Both the work and the price rest on three answers — which fluid, what quantity, and if it has run — so we ask. No one heads out until you have heard our quote over the phone.

Emptying that tank comes next, followed by a thorough flush of your system. Not like petrol, AdBlue forms crystals and attacks certain fuel-system metals, and none of that washes out by itself. That is why it counts more. A test comes last: before that, clean diesel goes in, and your filter is flushed or changed as needed. We don't go until it has been started and is running properly.

Unrun cars usually need a half-hour visit after arrival. The kit is safe on a busy filling station, and hushed enough for a residential street after dark. No money upfront; you settle up that day. At the end, the VAT invoice and a report from the engineer are handed to you for your insurer. Plenty of insurance policies include misfuelling cover, so it's worth checking yours whilst we're on the way.
