--- title: Explained: AdBlue in a Diesel Tank Staincross canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/staincross-south-yorkshire/ location: Staincross county: South Yorkshire latitude: 53.586140 longitude: -1.502890 service: AdBlue in a Diesel Tank updated: 2026-10-22 --- # How It Occurs and How to Avoid It: AdBlue in a Diesel Tank in Staincross If AdBlue is already in your diesel tank, stop reading for a moment: leave your engine and the ignition off then phone 0333 366 0103. In Staincross, catching it before your motor turns usually leaves a drain and a full flush where it stands. The rest of this page covers why it takes place and how to make sure it doesn't — useful if you are reading before it has happened. ## Two fillers, two tanks: AdBlue in a diesel vehicle No single fluid but two: that is what plenty of modern diesels around Staincross and Low Barugh carry, with diesel for your motor. Kept in a tank of its own, AdBlue is fed into your exhaust gas and cleans it. Each tank has one filler of its own. Other cars keep the AdBlue filler in your boot or under the bonnet; plenty more have both side by side behind one flap. At the petrol pump, your diesel side is topped up constantly. Rarely topped up, AdBlue normally goes in from a bottle, poured by a driver who has to stop and think what filler it needs. The error lives in that gap. ## Staincross: how AdBlue in the diesel tank happens It is seldom carelessness. Three things tend to line up. Haste comes from the warning. The vehicle tells you as AdBlue runs low, and an empty tank sends it into limp mode — so the top-up gets done in a rush, before work on a driveway off Spark Lane, or on the way home in the car park outside The Wentworth Arms. The old car's filler is where your hand reaches — yet a hire car, a new motor or a company car puts the fillers somewhere else. That is the second thing: a new vehicle. Third, the bottle fits: a diesel filler or AdBlue one, it goes in just as readily, and after the tip begins, no part stops it. The same few seconds settle it, in the middle of Staincross or out in Mapplewell. ## Telling the AdBlue filler from the diesel filler A few seconds is all these take — so check them before you tip anything, on a driveway in Darton or a forecourt around Staincross. - Colour and lettering: an AdBlue cap is commonly blue, or says "AdBlue", where a diesel cap usually doesn't. Trust the cap, not where it sits. - Look at the size: the smaller neck is, on many vehicles, the AdBlue one. - A label inside your fuel flap often says which fuel goes where, on many cars. Look for it. - Cannot find it next to the diesel inlet? In that case look beneath the bonnet or in the boot — the owner's manual will say which. - Collecting a hire or company car, perhaps at the car park at Darton? Check with whoever drove the car last before leaving, rather than once the light goes on. ## Keeping AdBlue out of your diesel tank when you top up Wherever in South Yorkshire the light comes on, here is a routine for that day. - Stop somewhere level, engine off, with time in hand — never rushing on the side of Towngate. - Say "AdBlue" out loud as you unscrew the cap, once finding the AdBlue filler and reading it. Silly, perhaps, yet it works. - The diesel cap stays on. Where both share a flap, make sure it's shut before the bottle comes up. - Tip slowly, using the bottle's own spout. Stop when it's 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. Find at the second or third step that the bottle went into the diesel filler? That is where you stop. Do not go on to step five. ## Already put AdBlue in the diesel tank in Staincross? Short list, then. First: the engine remains unstarted. On plenty of diesels the ignition alone runs the fuel pump, so do not switch it on. Thinning it with more diesel fails, since AdBlue settles to the base instead of blending — and that is where the fuel is pulled from. If you are on a forecourt, whether it's the Shell or the another forecourt nearby, ask the attendants to help roll the car clear of the petrol pump. Leave it where it is if you're on your own drive in Staincross. Where your motor has run by now, pull over somewhere safe then switch the vehicle off. On the M1, under 3 miles from Staincross, that means the next exit. A short hop across Staincross is a smaller job than a run towards Wakefield, under 10 miles away, so tell us about how far it went. ## What occurs when our engineers arrive around Staincross We come to the car wherever it has stopped, whether that is outside Mapplewell Primary School, near Staincross Christian Fellowship or on your own drive. We ask what went in, roughly how much, and whether it has run, since those answers settle the work and our quote. No one sets off before you've heard our quote by phone. After that: a drain, then a full flush of the entire system. With AdBlue that counts more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, and so it doesn't wash out on its own. The filter cleaned or, where needed, replaced; clean diesel in; then a test of your vehicle. Before we leave, we fire it up and confirm that it's running smoothly. Most jobs are done in about half an hour after our technicians get there, as long as the engine hasn't run — and the pumps we use are fine on a live forecourt yet quiet after dark outside a house. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Plenty of insurance policies include misfuelling cover, so it's worth checking yours whilst we're on the way. ## About Staincross and where it is Staincross is a village in South Yorkshire, situated inland at an elevation of 101 metres, approximately 6.7 miles from Wakefield.
