Turpin Green: How Does AdBlue End Up in a Diesel Tank, and How Do You Avoid It?

Leave the motor and ignition off and call 0333 366 0103 now — reading can wait if AdBlue is already in the diesel tank. Usually, if the motor has not run, it's drained and thoroughly flushed where the car is around Turpin Green. Nothing happened yet? Below, the page explains the why it takes place and the how to prevent it altogether.

AdBlue in a diesel vehicle, and its separate tank

Diesel goes to your motor — but plenty of newer diesels seen about Turpin Green and Broadfield carry a second fluid as well. Your exhaust, not the motor, is where AdBlue goes: dosed into the gas to fresh them, from its own tank.

Each tank has its own filler. Plenty of vehicles share a single flap for the two, whereas some put the AdBlue filler to the boot or under the bonnet. Diesel gets filled on each filling station visit, week in, week out. A driver who has to stop and think where it goes usually fills the AdBlue side, from a bottle, and far less commonly. It's in the gap that the error happens.

How does AdBlue in your diesel tank take place in Turpin Green?

Carelessness rarely causes it. What does is three things lining up at once.

To start with, the warning. Low AdBlue brings a message from the vehicle, and running dry means limp mode — hence a hurried top-up, perhaps before work off Starkie Street, perhaps outside The Leyland Lion on the way home after work.

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

And the bottle fits. A bottle with a spout goes into a diesel filler as easily as an AdBlue one, and so nothing stops the tip after it has started. Whether it occurs in Golden Hill or the middle of Turpin Green, it is the same few seconds.

Flushing a diesel fuel system after AdBlue, Turpin Green

Which filler is for AdBlue, and which for diesel?

A couple of seconds is all these take — so check them before you pour anything, on a driveway in Farington or a forecourt in Turpin Green.

  • The cap. The AdBlue cap is frequently blue, or marked "AdBlue". Your diesel cap usually isn't. Read it rather than going by where it sits.
  • On plenty of cars, the size tells: AdBlue gets the smaller filler neck.
  • The flap. Look inside the fuel flap for a label. Plenty of cars say there which fuel goes where.
  • The handbook shows which it is when the filler is not next to the diesel cap: your boot, or under the bonnet.
  • The previous driver will know. Check as you collect a hire car or fleet car — from Leyland's car park, say — rather than once the warning comes on.

Topping up AdBlue without it reaching your diesel tank

Anywhere across Lancashire the light comes on, this is a routine for that day.

  • Turn off once parked — level ground, motor off, and never in a rush beside Canberra Road on the verge.
  • Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds silly and it works.
  • If both sit under one flap, check the diesel cap is still closed before you lift the bottle — then leave the vehicle on.
  • Finish once your tank is topped up or the bottle is empty; until then, pour slowly using the built-in spout.
  • Before starting the vehicle, shut the cap and check a second time that the diesel cap never opened off.

If at step two or three you find you have already poured into your diesel side, stop there. Skip step five altogether.

Put AdBlue in the diesel tank in Turpin Green already?

The short order of things, starting with no starting your engine. The fuel pump runs on many diesels the moment your ignition goes on — so leave it off. AdBlue does not 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.

On a forecourt — Morrisons, Shell or another — the staff will usually help roll your car away, when you ask. At home in Turpin Green? Then the vehicle stays put.

Already started? Stop when it's safe, then switch off. Come off the M6 — under a mile out of Turpin Green — at the next exit. Roughly how far did it go? Crossing Turpin Green is smaller a job than a trip of under 5 miles towards Preston, and so tell us.

When our engineers arrive around Turpin Green, what takes place?

Our van reaches the car anywhere it stopped — your own drive, beside Leyland Methodist Church, or by Leyland Methodist Junior School. Both the work and our price rest on three answers — which liquid, what amount, and if it has run — so we ask. You hear that quote on the phone, before anyone sets off.

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, and so it doesn't wash out on its own — which is why that counts more here than with petrol. The filter flushed or, where needed, replaced; clean diesel in; then a test of the vehicle. Next our technicians start the car and check it runs correctly before we go.

Most jobs are finished in roughly half an hour after our technicians arrive, as long as the engine hasn't run — and the pumps we use are safe on a live forecourt yet quiet at night beside a house. Payment happens on the day, not upfront, and you are given the paperwork your insurer asks for: an engineer's report and a VAT invoice. Wrong-fuel cover is part of many insurance policies — and so make use of the wait to check yours.
