--- title: AdBlue in a Diesel Tank St Chloe? Read This canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/st-chloe-gloucestershire/ location: St Chloe county: Gloucestershire latitude: 51.714760 longitude: -2.226040 service: AdBlue in a Diesel Tank updated: 2026-10-17 --- # Preventing AdBlue in a Diesel Tank in St Chloe: Why It Happens If AdBlue is already in your diesel tank, stop reading for a moment: leave the engine and the ignition off and ring 0333 366 0103. Caught before the engine runs, it's usually a drain and a thorough flush, done where your car is in St Chloe. Here before the event? In that case what follows explains why it comes about and how to prevent it ever happening. ## AdBlue in a diesel car: two tanks, two fillers Diesel goes to your engine — yet plenty of modern diesels seen about St Chloe and South Woodchester hold another liquid too. AdBlue goes to your exhaust, where it is sprayed into the gas to clean it, and it lives in a tank of its own. There's a filler on 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. The diesel side is fuelled at the petrol pump all the time. Rarely topped up, AdBlue normally goes in from a bottle, poured by a driver who must stop and think what filler to use. Mistakes happen in that gap between the two. ## How does AdBlue in your diesel tank occur around St Chloe? Three things tend to line up, and carelessness is rarely one of them. On a driveway off St Loes Pitch before work, or in the car park at The Black Horse on the way home: that's where the rushed top-up takes place. Why the rush? As AdBlue gets low the car warns you, and if it is empty, limp mode kicks in. Then the car is new. A hire car, a new car or a company car puts the fillers where your last one didn't, and the hand hits for the cap it would have used on the old one. A spout-topped bottle finds no obstacle at a diesel filler any more than at an AdBlue one. So the pour, once started, carries on. Whether it takes place in Littleworth or the middle of St Chloe, it is the same few seconds. ## The AdBlue filler and the diesel filler: telling them apart Whether a St Chloe forecourt or a driveway out in Amberley, spend a couple of seconds on these before anything is poured in. - Read the cap rather than going by position: AdBlue caps are often blue or marked "AdBlue", and diesel caps usually are not. - Many cars give AdBlue the smaller neck of the two. - A label inside your fuel flap frequently shows which fuel goes where, on plenty of cars. Look for it. - The handbook. If your filler isn't by your diesel cap, it is in your boot or under the bonnet, and the handbook says which. - The person who drove it last. On a hire or company car picked up from somewhere like the car park at Stroud, ask before you leave, not when the light comes on. ## AdBlue top-ups that never reach your diesel tank A routine for the day the light comes on, wherever across Gloucestershire that is. - Stop on level, engine off, with time to spare — not hurried on the side of St Chloe Mead. - 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 your diesel cap is still closed before you lift the bottle — and leave the car on. - Tip slowly, using the bottle's own spout. Stop when it is full or when the bottle is empty. - Shut the cap, then look once more — confirm your diesel filler stayed shut the whole time. Only then, start your car. Spot at step two or three that it's already gone into the diesel side? So stop right there. Stage five is out. ## St Chloe: already put AdBlue in your diesel tank? Then the order of things is short. Don't start the motor. The fuel pump runs on plenty of diesels the moment the ignition goes on — so leave it off. Topping up with diesel won't weaken it: rather than mixing, AdBlue sinks to the base of the tank, just where fuel is drawn from. The staff at Shell, Esso or another forecourt will usually lend a hand pushing your car away if you ask. On your own drive around St Chloe? So the car stays where it is. If your motor has already run, stop as soon as it is safe and switch off. On the M5, under 10 miles from St Chloe, that means the next exit. Distance matters — a quick hop across St Chloe is a smaller job than heading under 15 miles to Gloucester — so say about how far it went. ## St Chloe: what occurs when our engineers arrive Our van reaches the car anywhere it stopped — your own drive, near Amberley War Memorial, or outside Amberley Parochial School. Which liquid went in, the quantity, and whether it ran: we ask because those replies decide the work and quote. Nobody heads out before you've heard our quote by phone. Your system is then purged thoroughly, after your tank is cleared. 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 the flush counts more here than with petrol. Testing is last: before that, clean diesel is added, and the fuel filter is cleaned or replaced if necessary. We don't go until it has been fired up and is running correctly. Most jobs are done in roughly half an hour after our engineers get there, provided your motor hasn't run — and the pumps we use are safe on a live forecourt yet quiet after dark beside a house. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Wrong-fuel cover is included in many insurance policies — and so use the wait to look at yours. ## About St Chloe and where it is St Chloe is a village in Gloucestershire, situated on the riverside at an elevation of 119 metres, with detached housing being the predominant type of accommodation.
