--- title: AdBlue in a Diesel Tank Lowton St Marys: Explained canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/lowton-st-marys-greater-manchester/ location: Lowton St Marys county: Greater Manchester latitude: 53.468890 longitude: -2.572730 service: AdBlue in a Diesel Tank updated: 2026-10-21 --- # Lowton St Marys: How Does AdBlue End Up in a Diesel Tank, and How Do You Prevent It? AdBlue already in the diesel tank? In that case set this page aside for now, keep your ignition and engine off, and phone 0333 366 0103. A drain plus a thorough flush, carried out just where your car sits around Lowton St Marys, is normally what it needs when found before the engine runs. If you're reading before it has happened, the rest of this page is about why it occurs and how to make sure it does not. ## AdBlue in a diesel vehicle, and its separate tank Plenty of newer diesels on the roads round Lowton St Marys and Bank Heath carry two liquids, not one. Diesel goes to the engine. AdBlue goes to the exhaust, where it is sprayed into the gas to fresh it, and it lives in a tank of its own. There's a filler on each tank. Other cars keep the AdBlue filler in your boot or under the bonnet; a lot more place the two together under one flap. The diesel side is topped up at the pump all the time. Much less commonly, the AdBlue side is filled — mostly from a bottle, by a person working out where it goes. That gap is where the slip lives. ## How AdBlue in your diesel tank happens around Lowton St Marys Carelessness rarely explains it. What does is three things coming up at once. On a drive off Bradwell Road before work, or in the car park at Red Lion on the way home: that is where the rushed top-up takes place. What is the reason for the rush? As AdBlue gets low the car tells you, and if it is empty, limp mode follows. Unfamiliar vehicles are second, as well. Hire cars, new cars and company vehicles place their fillers differently, and habit reaches for the cap used on the old one. 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 once it has started. The same few seconds settle it, in the middle of Lowton St Marys or out in Lane Head. ## The AdBlue filler and the diesel filler: telling them apart Whether a Lowton St Marys forecourt or a driveway out in Town of Lowton, take a few seconds over these before anything goes in. - Check the cap instead of going by where it sits: AdBlue caps are commonly blue or marked "AdBlue", and diesel ones normally are not. - The size. On plenty of motors the AdBlue filler neck is the smaller of the two. - Check inside the fuel flap: many cars have a label there showing which fuel goes where. - The handbook says which it lives if the filler isn't next to your diesel cap: your boot, or under the bonnet. - Ask the person who drove it last — before you leave, not when the light comes on — when you collect a hire or company car from somewhere like the car park outside Newton-Le-Willows. ## AdBlue top-ups that never reach your diesel tank The day the light goes on, wherever around Greater Manchester, follow this routine. - Not in a rush on the side of Martland Avenue, not on a slope, not with your motor running: park then switch off first. - Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds daft and it works. - The diesel cap remains on. Where both share a flap, make sure it is shut before the bottle comes up. - Tip slowly, using the bottle's own spout. Stop when it is full or when the bottle is empty. - Only then, start your car: close the cap, check a second time, and make sure the diesel cap was never opened. Stop there if you find, at stage two or three, that you've already poured into the diesel side. Step five stays out. ## AdBlue in your diesel tank already, in Lowton St Marys? Then the order of things is short. Do not start the engine. On plenty of diesels your ignition alone runs the fuel pump, and so don't switch the vehicle on. AdBlue doesn't mix with diesel — it sinks to the bottom of the tank, where the fuel is drawn from — so don't top up with diesel to thin it. Ask the staff to help roll the vehicle clear of the pump if you are on a forecourt — the Esso, the Paul Hesketh or somewhere else. On your own drive in Lowton St Marys? So the vehicle stays where it is. Stop as soon as it is safe then switch off, if your engine has already run. On the M6, under 3 miles from Lowton St Marys, that means the next exit. A short hop across Lowton St Marys is a smaller job than a run towards Salford, under 15 miles away, so tell us about how far it went. ## When our engineers get there around Lowton St Marys, what happens? The van comes to your car anywhere it stopped — your own drive, near Lowton Community Church, or by St Luke's CofE Primary School. Both the work and our price depend on three replies — which fluid, which amount, and whether it's run — so our engineers ask. You hear that quote by phone, before anyone heads out. Then your tank is drained and the system cleaned thoroughly. With AdBlue that matters more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, so it doesn't wash out on its own. The fuel filter is flushed, or replaced where it needs to be; fresh diesel goes in; and the vehicle is tested. Before we go, we start it and confirm that it is running correctly. Most jobs are finished in roughly half an hour after our engineers get there, as long as the engine has not run — and the pumps our technicians use are safe on a live forecourt yet quiet at night beside a house. The insurer will ask for an engineer's report and the VAT invoice, and both are yours at the end. Payment is on the day, with no deposit. It is worth looking at your policy as the van travels to you: misfuelling cover is included with many policies. ## About Lowton St Marys itself Lowton St Marys is a suburban area in Greater Manchester, situated inland at an elevation of 39 metres, and is located near the towns of Lane Head, Lowton, and Lowton Heath.
