--- title: Oultoncross: AdBlue in a Diesel Tank, Explained canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/oultoncross-staffordshire/ location: Oultoncross county: Staffordshire latitude: 52.911840 longitude: -2.140970 service: AdBlue in a Diesel Tank updated: 2026-10-05 --- # How It Happens and How to Avoid It: AdBlue in a Diesel Tank in Oultoncross Stop reading for a moment when your diesel tank already holds AdBlue in it: ignition off, motor off, then phone 0333 366 0103. Usually, when your motor has not turned, it's drained and fully purged where the vehicle sits in Oultoncross. The rest of this page explains why it happens and how to make sure it doesn't — handy if you are reading before it has happened. ## Why does AdBlue in a diesel motor need its own filler? Plenty of modern diesels on the roads about Oultoncross and Stone carry two liquids, not one. Diesel goes to your motor. The exhaust, not the motor, is where AdBlue ends up: dosed into the fumes to fresh it, from a separate tank. There is a filler for each tank. On a lot of vehicles the two sit side by side under the same flap; on others the AdBlue filler is in the boot or under the bonnet. Topping up your diesel side at the pump happens all the time. A driver who has to stop and work out where it goes usually fills the AdBlue side, from a bottle, and much less frequently. The mistake grows in the gap between the two. ## How does AdBlue in your diesel tank take place in Oultoncross? Carelessness rarely causes it. Instead is three things coming up at once. First, the warning. Low AdBlue triggers a warning from the car, and running out leads to limp mode — so a hurried top-up, perhaps before work off Airdale Road, or at The Pheasant on the way home that evening. The old car's filler is where the hand reaches — yet a hire car, a new car or a company car puts the fillers somewhere else. That's the second thing: an unfamiliar motor. 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 pour after it has started. It takes a few seconds, be it in Oulton Grange or bang in the centre of Oultoncross. ## How to tell the AdBlue filler from the diesel one Whether a Oultoncross forecourt or a drive out in Oulton Heath, take a few seconds over these before anything is poured in. - Check the cap rather than going by where it sits: AdBlue caps are commonly blue or marked "AdBlue", and diesel caps usually aren't. - Look at the size: the smaller neck is, on many cars, the AdBlue one. - Check inside your fuel flap: many motors have a label there saying which fuel goes where. - The handbook. If your filler is not by the diesel cap, it is in the boot or under the bonnet, and the handbook says which. - The person who drove the car last. On a hire or company car picked up from somewhere like the car park outside Stone, ask before you leave, not when the light comes on. ## Topping up AdBlue without it reaching your diesel tank When the light comes on, wherever across Staffordshire, use this routine. - Pull in on level, motor off, with time to spare — not hurried on the side of Nicholl's Lane. - Say "AdBlue" out loud as you unscrew the cap, after you find the AdBlue filler and read it. Silly, yes, yet it does the trick. - If both sit under one flap, check your diesel cap is still closed before you lift the bottle — then leave the car on. - Using the bottle's own spout, pour slowly — and stop when it's full or the bottle is empty. - Only then, start your car: close the cap, check a second time, and make sure your diesel cap was never opened. Stop there if you find, at step two or three, that you have already poured into your diesel side. Step five stays out. ## Oultoncross: already put AdBlue in your diesel tank? Then the order of things is short. Do not start your motor. On many diesels your ignition alone runs the fuel pump, and so do not switch the vehicle on. Don't top up with diesel to dilute it: AdBlue doesn't mix with diesel, it sinks to the bottom of that tank, where your fuel is drawn from. If you're at a forecourt, whether it is the Morrisons or the BP, ask the staff to help push the car clear of the petrol pump. If you are on your own drive in Oultoncross, leave it where it stands. When the motor has been run already, stop somewhere safe and turn the vehicle off. Come off the M6 — under 3 miles out of Oultoncross — at the next exit. About how far did it go? Crossing Oultoncross is smaller work than a run of under 10 miles to Stoke-on-Trent, and so tell us. ## When our technicians arrive around Oultoncross, what occurs? The van comes to the vehicle wherever it stopped — your own drive, near Alleyne's Sports Centre, or by Christ Church CofE First School. Both the work and the price depend on three answers — what fluid, which amount, and whether it's run — so we ask. You get that quote on the phone, before anybody heads out. The fuel system is then purged thoroughly, after the tank is cleared. Not like petrol, AdBlue leaves crystals and attacks certain fuel-system metals, and neither clears out by itself. That is why it matters more. Your filter is flushed, or replaced where it needs to be; fresh diesel goes in; and the vehicle is tested. Your engine is started next and tested to confirm it runs smoothly, all before we leave. If your motor has not run, the majority of jobs take about half an hour once we are there, using pumps that are fine on a busy forecourt and quiet enough to use outside a house at night. Your insurer usually wants the engineer's report and the VAT invoice, and both are yours once the job is done. Payment comes on the day, with no money upfront. While we travel, take a look at your policy; plenty include cover for misfuelling. ## About Oultoncross itself Oultoncross is a suburban area situated on the riverside in Staffordshire, with a mix of terraced housing and a population of around 1454 residents.
