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

Stop here a minute when your diesel tank already holds AdBlue in it: ignition off, motor off, and ring 0333 366 0103. Around St Pauls, catching it before your engine runs normally leaves a drain and a full flush where it stands. Reading in advance? Then what follows covers how it comes about and how to prevent it happening at all.

Two fillers, two tanks: AdBlue in a diesel car

Many modern diesels on the roads about St Pauls and Pittville carry two liquids, not one. Diesel goes to your engine. Your exhaust, not your engine, is where AdBlue goes: sprayed into the gas to clean it, from a separate tank.

Each tank has its own filler. On a lot of cars the two sit side by side under the same flap; on others the AdBlue filler is in your boot or under the bonnet. The diesel side is filled at the petrol pump all the time. Rarely filled, AdBlue usually comes out of a bottle, tipped by a driver who must stop and think what filler to use. It's in the gap that the mistake lives.

How does AdBlue in the diesel tank take place in St Pauls?

Three things tend to line up, and carelessness is rarely one of them.

Haste follows from the warning. Your car tells you as AdBlue runs low, and a dry tank puts the vehicle into limp mode — so the top-up gets done quickly, before work on a drive off Victoria Street, or heading home in the car park at Horse and Jockey.

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

No part stops the pour once it has started, because a bottle with a spout goes into a diesel filler as readily as an AdBlue one. The bottle fits. It's a few seconds, be it out in Cheltenham or bang in the heart of St Pauls.

Flushing a diesel fuel system after AdBlue, St Pauls

Telling the AdBlue filler from your diesel filler

Look at these before pouring, at a forecourt around St Pauls or a drive out in Overton Park. A few seconds, no more.

  • Where it sits misleads; the cap doesn't. AdBlue ones are often blue or carry the word "AdBlue" — diesel ones normally do not.
  • Many vehicles fit AdBlue the smaller filler of the two.
  • A label inside your fuel flap frequently says which fuel goes where, on plenty of motors. Check for it.
  • The handbook says where it lives when your filler isn't next to the diesel cap: your boot, or under the bonnet.
  • The person who drove it last. On a hire or company car collected from somewhere like the car park at Cheltenham Spa, ask before you leave, not when the light comes on.

AdBlue top-ups that never reach the diesel tank

The day the light comes on, wherever in Gloucestershire, follow this routine.

  • Turn off after you park — flat ground, motor off, and never rushed by Margrett Road on the verge.
  • Say "AdBlue" out loud as you unscrew the cap, once you find the AdBlue filler and reading it. Daft, yes, but it does the trick.
  • The diesel cap remains on. Where the two share a flap, make sure it's shut before the bottle comes up.
  • Gently is best, through the bottle's own spout, until it's full or the bottle runs out.
  • Before starting the vehicle, close the cap and check a second time that the diesel cap never opened off.

Spot at stage two or three that it has already gone into your diesel side? So stop right there. Leave out stage five entirely.

Put AdBlue in your diesel tank in St Pauls already?

The short order of things, starting with no starting the motor. The fuel pump starts on plenty of diesels as soon as your ignition is switched on — and so leave it off. Do not top up with diesel to thin it: AdBlue does not mix with diesel, it sinks to the bottom of your tank, where your fuel is pulled from.

Ask the attendants to help push the vehicle away from the petrol pump if you're on a forecourt — the Tesco, the Shell or somewhere else. Your own driveway in St Pauls is where it stays.

Stop as soon as it is safe and switch off, if your motor has already run. The next exit means where to leave if you're on the M5, under 3 miles from St Pauls. Mileage matters — a quick hop across St Pauls makes a smaller job than driving under 10 miles towards Gloucester — so say about how far it went.

Our arrival around St Pauls, and what occurs next

Wherever the car came to rest, be it by The Catholic School of Saint Gregory the Great, beside Francis Close Hall Chapel or at home, the van comes to it. Our technicians ask what was put in, roughly how much, and if it has run, since those replies settle this work and the price. You get that quote by phone, before anybody heads out.

Draining that tank comes next, followed by a full flush of your 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 with AdBlue than with petrol. The fuel filter is flushed, or replaced where it needs to be; clean diesel goes in; and your car is tested. Before leaving, we fire it up and confirm that it is running smoothly.

Unstarted cars usually mean a half-hour job after the moment we arrive. The kit is safe on a live forecourt, and quiet enough for a driveway late at night. No money in advance; you settle up that day. Afterwards, the VAT invoice and a report from the engineer are handed to you for the insurer. Plenty of insurance policies include misfuelling cover, so it is worth checking yours while we're on the way.
