Guilsfield: How Does AdBlue End Up in a Diesel Tank, and How Do You Prevent It?
Keep your motor and ignition off then phone 0333 366 0103 first — the rest can wait when AdBlue is already in the diesel tank. Normally, when your motor hasn't run, it is drained and fully purged where the vehicle is in Guilsfield. If you're reading before it has happened, the rest of this page is about why it takes place and how to make sure it doesn't.
Why does AdBlue in a diesel vehicle need its own filler?
Not one liquid but two: that's how plenty of modern diesels near Guilsfield and Coed-y-wlad run, with diesel feeding the motor. The exhaust, not your motor, is where AdBlue ends up: sprayed into the fumes to clean them, from its own tank.
There's a filler for every tank. Many of cars have a single flap for both, while some move the AdBlue filler to your boot or under the bonnet. Topping up the diesel side at the pump happens all the time. Much less commonly, the AdBlue side is filled — mostly from a bottle, by someone thinking about where it goes. The mistake lives in that gap.
How does AdBlue in the diesel tank happen in Guilsfield?
Three things tend to come together, and carelessness is rarely one of them.
The warning comes first. As AdBlue runs low the car tells you, and if it runs out completely, the car goes into limp mode. So the top-up is done in a hurry: on a drive off Park Road before work, or in the car park outside The Oak Inn on the way home.
Then your car is new. A hire car, a new car or a company car puts the fillers where your last one didn't, and your hand reaches for the cap it would have used on the old one.
Nothing halts 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. Groes-lwyd or the middle of Guilsfield: it takes the same few seconds in both.
Telling the AdBlue filler from the diesel filler
Before you tip anything, whether on a driveway in Groespluan or a forecourt around Guilsfield, check these. They take a few seconds.
- Read the cap instead of going by position: AdBlue caps are regularly blue or marked "AdBlue", and diesel caps usually are not.
- On many vehicles, the size gives it away: AdBlue gets the smaller filler neck.
- Open the filler flap and check for a label — plenty of motors mark which goes in which inlet right there.
- Cannot see it next to the diesel filler? Then look below the bonnet or in the boot — the owner's manual will say where.
- Ask the person who drove it last — before you leave, not when the light comes on — if you pick up a hire or company car from somewhere like the car park outside Welshpool.
Topping up AdBlue without it reaching your diesel tank
A routine for the day the light comes on, wherever around Powys that is.
- Turn off once parked — flat ground, motor stopped, and never rushed beside B4392 at the roadside.
- Silly as it sounds, speaking "AdBlue" aloud as you unscrew the cap works — once you have located the filler and read the cap.
- The two under a single flap? So confirm the cap on the diesel filler is still closed ahead of lifting the bottle.
- Pour slowly, using the bottle's own spout. Stop when it is full or when the bottle is empty.
- Close the cap and check a second time. Make sure the diesel cap was never opened. Only then start the car.
Stop there if you find, at stage two or three, that you've already poured into the diesel side. Skip step five entirely.
Put AdBlue in the diesel tank in Guilsfield already?
Then the order of things is short. Don't start your engine. The fuel pump starts on many diesels as soon as the ignition is switched on — and so leave it off. AdBlue does not mix with diesel — it sinks to the bottom of the tank, where your fuel is pulled from — so don't top up with diesel to thin it.
Ask the staff to help push the vehicle away from the petrol pump if you're at a forecourt — the Texaco, the Shell or somewhere else. If you are on your own driveway around Guilsfield, leave the vehicle where it stands.
Stop as soon as it is safe and switch off, if the motor has already run. On the M54, under 50 miles from Guilsfield, that means the next exit. Mileage counts — a quick hop across Guilsfield makes a smaller job than heading under 50 miles to Wrexham — so say about how far it went.
Our arrival around Guilsfield, and what happens next
Anywhere the car has stopped, whether by the local primary school, near St Aelhaiarn , Guilsfield or at home, the van comes to it. We ask what got in, roughly how much, and whether it's run, since those answers decide this work and the quote. On the phone call itself, you are told our price — before anything else.
Your system is then rinsed thoroughly, after your tank is drained. AdBlue crystallises and is corrosive to some of the metals in a fuel system, so it does not wash out on its own — which is why that counts more with AdBlue than with petrol. The filter flushed or, where it must be, swapped; fresh diesel in; and then a check of the car. The motor is started next and checked to confirm it runs correctly, all before our engineers go.
Using pumps safe on a busy forecourt and quiet enough to use outside a house at night, most jobs in which the motor has not run take roughly half an hour after our engineers arrive. No money in advance; you settle up on the day. At the end, the VAT invoice and the report from the engineer go to you for your insurer. Misfuelling cover is included in plenty of insurance policies — so make use of the wait to check yours.
