Millikenpark: How Does AdBlue End Up in a Diesel Tank, and How Do You Prevent It?

Pause reading for a moment if your diesel tank already has AdBlue in it: ignition off, motor off, then ring 0333 366 0103. A drain plus a full flush, carried out just where the vehicle sits in Millikenpark, is usually what it needs if found before the motor runs. The rest of this page covers why it takes place and how to ensure it doesn't — useful if you're reading ahead of time.

AdBlue in a diesel motor: two tanks, two fillers

Diesel feeds the engine — yet plenty of current diesels driven around Millikenpark and Howwood Road hold another liquid as well. Your exhaust, not your engine, is where AdBlue ends up: dosed into the gas to clean it, from a separate tank.

Each tank has its own filler. Some cars put the AdBlue filler in the boot or under the bonnet; a lot more have both side by side under one flap. The diesel side is filled at the pump all the time. Seldom filled, AdBlue usually goes in out of a bottle, poured by someone who has to stop and think what cap to use. The mistake grows in that gap between them.

Millikenpark: how AdBlue in your diesel tank occurs

Carelessness seldom causes it. Instead is three things coming up at once.

First, the warning. Low AdBlue triggers a message from the car, and running out means limp mode — so a hurried top-up, perhaps before work off Ladysmith Avenue, perhaps outside The Spateston Inn on the way home that evening.

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

No part stops the pour after it has started, because a bottle with a spout goes into a diesel filler as easily as an AdBlue one. The bottle fits. Whether it occurs in Tandlehill or the middle of Millikenpark, it is the same few seconds.

How to tell the AdBlue filler from the diesel one

Before you tip anything, whether on a drive in Kilbarchan or a forecourt in Millikenpark, check these. They take a couple of seconds.

  • Position can mislead; the cap does not. AdBlue caps are often blue or carry the name "AdBlue" — diesel caps normally do not.
  • Many vehicles give AdBlue the smaller filler of the two.
  • A label inside the fuel flap often shows which fuel goes where, on plenty of motors. Look for it.
  • The handbook. If your filler isn't by your diesel cap, it's in the boot or under the bonnet, and the handbook says which.
  • Collecting a hire or company car, perhaps at the car park at Milliken Park? Check with whoever drove the vehicle last before leaving, not when the light comes on.

Topping up AdBlue without it reaching the diesel tank

The day the light goes on, anywhere across Renfrewshire, follow this routine.

  • Turn off after you park — level ground, motor off, and never in a rush beside Waterside Way on the verge.
  • Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds daft and it works.
  • The diesel cap stays on. Where the two share a flap, make sure it is shut before the bottle comes up.
  • Using the bottle's own spout, tip slowly — and stop when it is full or the bottle is empty.
  • Close the cap and check again. Make sure the diesel cap was never opened. Only then start the vehicle.

Find at the second or third stage that AdBlue went in the wrong tank? That is where you stop. Don't carry on to stage five.

Already put AdBlue in your diesel tank around Millikenpark?

Short order, then. Top of it: your motor stays unstarted. The fuel pump starts on many diesels the moment the ignition goes on — and so leave it off. AdBlue doesn't mix with diesel — it sinks to the bottom of the tank, where your fuel is drawn from — so don't top up with diesel to thin it.

At a forecourt — Morrisons, Esso or another — the staff will normally help roll the car away, if you ask. Leave it where it is if you are on your own driveway around Millikenpark.

Already run? Pull over when it is safe, then turn off. The next exit is the place to leave when you're on the M8, under 5 miles from Millikenpark. A short hop across Millikenpark is a smaller job than a run towards Glasgow, under 15 miles away, so tell us roughly how far it went.

When our technicians get there in Millikenpark, what occurs?

Our engineers come to the vehicle wherever it has stopped, whether that is outside the local primary school, close to War Memorial or on your own driveway. Both the work and the quote rest on three replies — which fluid, what quantity, and if it's run — so our engineers ask. The quote is given on the call, ahead of any van leaving.

Then the tank is cleared and the system rinsed thoroughly. More than with petrol, it counts with AdBlue: crystals build up, certain metals are attacked, and nothing washes away on its own, no matter how long it sits. A test is at the end: before that, fresh diesel goes in, and the fuel filter is flushed or changed if necessary. The motor is started next and tested to make sure it runs properly, all before our engineers head off.

Using pumps fine on a busy forecourt and quiet enough to use outside a house at night, most jobs where the motor has not run take about half an hour once our technicians arrive. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Wrong-fuel cover is part of many insurance policies — and so use the wait to look at yours.
