--- title: AdBlue in a Diesel Tank Read? Read This canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/read-lancashire/ location: Read county: Lancashire latitude: 53.806270 longitude: -2.354540 service: AdBlue in a Diesel Tank updated: 2026-10-11 --- # Preventing AdBlue in a Diesel Tank in Read: Why It Occurs Keep your engine and ignition off then ring 0333 366 0103 now — reading can wait when AdBlue is already in the diesel tank. In Read, finding it before the motor turns usually means a drain and a thorough flush where it stands. The rest of this page covers why it occurs and how to make sure it does not — useful if you are reading before it has happened. ## Two fillers, two tanks: AdBlue in a diesel vehicle Many modern diesels around Padiham, as well as Read, carry on two fluids; your motor takes only your diesel. AdBlue goes to the exhaust, where it is sprayed into the gas to fresh it, and it lives in a tank of its own. Each tank comes with one filler of its own. Under one flap, next to each other: that's the layout on a lot of cars. On others, AdBlue's filler sits under the bonnet or in your boot instead. The diesel side is topped up at the pump all the time. Someone who has to stop and work out where it goes usually fills the AdBlue side, from a bottle, and far less frequently. The mistake lives in that gap. ## AdBlue in the diesel tank around Read: how it takes place Rarely is it carelessness: normally three things line up. First, the warning. Low AdBlue brings a message from your car, and letting it run out leads to limp mode — so a rushed top-up, perhaps before work off Worthalls Road, perhaps at Read and Simonstone Club on the way home that evening. New-to-you cars are second, too. Rentals, new cars and company cars put their fillers differently, and habit reaches for the cap used on the old one. Third, the spout goes in: diesel filler or AdBlue one, it goes in as readily, and once the tip begins, nothing stops it. Simonstone or the heart of Read: it takes the same few seconds either way. ## How to tell the AdBlue filler from the diesel one Check these before pouring, at a forecourt around Read or a driveway out in Hyndburn Bridge. A few seconds, that's all. - Check the cap rather than going by where it sits: AdBlue caps are frequently blue or marked "AdBlue", and diesel caps usually are not. - Plenty of vehicles give AdBlue the smaller neck of the two. - The flap. Look inside your fuel flap for a label. Plenty of motors say there which fuel goes where. - Can't see it next to the diesel filler? Then look below the bonnet or inside the boot — the handbook will say where. - Check with the person who drove it last — before you leave, not when the light comes on — if you collect a hire or company car from somewhere like the car park at Hapton. ## AdBlue top-ups that never reach your diesel tank On the day the warning appears — anywhere it is in Lancashire — a routine to use. - Switch off once parked — flat ground, engine off, and never in a rush beside Campbell Street on the verge. - Locate the AdBlue filler, check the cap, and say the word "AdBlue" out loud as you unscrew it. It seems silly. It works. - Leave the diesel cap on. If both sit under one flap, check the diesel cap is still closed before you lift the bottle. - Stop when the tank is topped up or the bottle runs dry; until then, tip slowly using the own spout. - Close the cap and check a second time. Make sure your diesel cap was never opened. Only then start your car. Find at step two or three that it has already gone into your diesel side? So stop right there. Never carry on to step five. ## AdBlue in the diesel tank already, around Read? Then the order of things is short. Do not start your engine. The fuel pump starts on many diesels as soon as your ignition is switched on — so keep it off. Do not top up with diesel to dilute it: AdBlue does not mix with diesel, it sinks to the bottom of the tank, where your fuel is pulled from. Ask the staff to help push your car away from the petrol pump if you are on a forecourt — the the nearest petrol station, the Texaco or somewhere else. Your own driveway in Read is where it should stay. Already run? Stop once it is safe, then switch off. Read sits under 3 miles from the M65; on it, use the next junction. Tell us roughly how far it went: a run towards Preston, under 15 miles away, is a bigger job than a short hop across Read. ## Our arrival around Read, and what takes place next Our van comes to the car wherever it stopped — your own drive, beside Read And Simonstone Village Hall, or outside Read St John's CofE Primary School. What liquid went in, the quantity, and whether it ran: our technicians ask since the answers decide the work and price. Nobody sets off before you have heard our quote by phone. Then the tank is drained and the system purged thoroughly. With AdBlue that counts more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, so it does not wash out on its own. Once your filter has been cleaned — or replaced, where required — clean diesel is added, and finally your car is tested. Then our technicians fire it up and confirm it runs properly before we leave. Unstarted vehicles usually need a half-hour visit from the moment we arrive. The kit is safe on a busy filling station, and quiet enough for a residential street after dark. Your insurer will ask for the engineer's report and the VAT invoice, and both are yours at the end. Payment comes on the day, with no money upfront. Misfuelling cover is included in many insurance policies — and so use the wait to check yours. ## About Read and where it is Read is a village in Lancashire, situated on the banks of a river at an elevation of around 114 metres.
