Rock: AdBlue in the Diesel Tank? Leave It Off
AdBlue in your diesel tank? Then leave the motor off — and the ignition too. In plain terms, AdBlue is just urea in water. The harm starts once it's sucked through your lines — it won't burn, and it won't combine with diesel. In Rock, AdBlue in a diesel tank caught before your engine runs usually comes down to a drain and a thorough flush, just where the car is. Before you do anything else, ring 0333 366 0103.
Rock, AdBlue in the diesel tank: what to do at once
Things to do:
- Pocket your keys, and that prevents someone switching the power on.
- Hazards on, if moving traffic is at all close.
- So you can tell us which fluid it was and roughly what quantity, save the till receipt or the empty bottle.
- Call right where you are. Quote a BT70 3 postcode or the nearest street sign, and nobody has to hunt for you.
Don't do these:
- Do not start your engine, even for a moment to move the vehicle.
- Turning your key to ignition by itself sets the pump going on many diesels. Skip it.
- Do not top up with diesel to thin it. AdBlue does not dilute in diesel; it separates out.
- Any driving at all is best avoided, even a short distance up Wallace Cottages.
- No draining it yourself, at all, at the verge.
Moving your vehicle off the pumps is a job for staff to help with, wherever Rock forecourt you are on, the the nearest petrol station or any other. On your own drive, don't move it at all.
What AdBlue does in a diesel tank
Not your engine but your exhaust is where AdBlue is meant to go. It goes into its own tank and is sprayed into your exhaust gas to fresh it. A fuel pump isn't designed to cope with it, and AdBlue was never intended to go through one.
Inside a diesel tank it acts very differently from fuel. It does not mix in. It is heavier than diesel, and so it sinks and collects at the bottom of that tank, which is where the pickup pulls fuel from. Simplest of all: a vehicle that had AdBlue in Pomeroy last night and has not turned since. The liquid waits at the foot of that tank, undrawn — but it will be first through once the motor runs, ahead of any diesel at all.
It does two kinds of harm from there. As its water goes, the urea left behind crystallises, and the crystals block filters and settle in fine passages. And it is corrosive to some of the metals a fuel system is made from, so it keeps running on the parts it gets to for as long as it remains there. Lines carrying AdBlue mean harm by morning for a vehicle sitting in Rock. Just in that tank, it stays stable. Water lubricates nothing. The injection pump and every injector depend on diesel running past them, so the water content damages them in its own right.
Why is AdBlue in a diesel regularly the bigger problem?
Put petrol in a diesel at the another forecourt nearby and you have an issue of thin fuel. Damage just comes from running on it. Mixed into the diesel and sitting in that tank, it does none.
AdBlue in a diesel is a different problem: not thin fuel, but no fuel at all. Not burning, it can't simply be run through. Whether the vehicle is in Donaghey or the centre of Rock, firing it up "to see" costs more with AdBlue than almost any other mistake, and the flush matters for more. The reasons: it won't stay blended, and so watering it down is impossible; and deposits and corrosion survive the next tankful.
As with petrol, there is good news. Not started? Then the AdBlue waits just inside the tank, the simplest section of the entire system to empty, wherever the car has come to rest across County Tyrone.
AdBlue in a diesel tank around Rock: how it ends up there
Plenty of vehicles put the AdBlue cap alongside the diesel one, now and then behind one flap, and after dark the two can look the same. Nobody means it. Most of the time it happens with a bottle bought on the way home and poured in on the drive, not at the pump.
It tends to occur in a couple of familiar ways. Hurrying, outside the local primary school, after a warning light flashed on during the school run, someone refills your car. Close to B842, a driver tips a bottle in on the drive in the evening. One more version: dim light, a pub car park by the pub in the village, and someone using that flap the first time.
It crops up the most in a hire car, a brand-new car, a fleet car, or the other motor of a home with both fuels — the vehicles people use the least. Same mistake, an identical first step — leave it off — wherever you happen to be around Rock or the rest of County Tyrone.
Rock: started the motor with AdBlue in your diesel tank?
Then your tank is no longer where the AdBlue is. It has been drawn through the fuel filter and the fuel lines, and if your motor ran for any time, it has reached your high-pressure pump and the injectors.
Perhaps returning from the green space at the edge of the village, or part way across Rock, your engine may go rough, smoke, drop pace, flash your dash or cut out. Pull over when safe. Switch off. Keep the vehicle off instead of restarting it to check. Each start pulls more of that through.
Leave the M77, over 50 miles from Rock, at the first junction and stop safely, rather than carrying on.
Hopping across Rock to the car park by the centre is one thing; heading towards Armagh, under 25 miles away, is another, because every mile pushes the AdBlue further in. So distance matters. Tell us roughly how far it had come.
There is more to flush once the motor has run, and our technicians do all of it where the car has stopped. Spotted early, it very seldom leaves lasting damage.
What clearing AdBlue from a diesel involves in Rock
Wherever it has stopped in Rock — a filling station, a layby, a driveway, a road beside a street just off the centre — our van comes to your vehicle. Which fluid got in, roughly how much, plus whether the engine has been run: our technicians check before all else, because those shape the work.
Then that tank is emptied where the vehicle sits, so the tainted fuel and the AdBlue come out together. With AdBlue, more so than with petrol, the flush counts: the fuel system is cleaned all the way through since residue won't flush out by itself. Clean diesel goes in after the fuel filter is flushed — or swapped, when it needs to be — and then your vehicle is tested. If your engine has not run, the majority of jobs take about half an hour once we arrive. Quiet enough to use outside a house at night, and safe on a busy forecourt, the pumps are explosion-proof.
New diesel goes in to prime your system, and that is the last step. After that we start the car and you drive off, whether from a parking bay by the nearest station or a drive around Rock. Our engineers make sure it runs smoothly on new diesel before we go. The whole job is done where your car is, so it never needs to go to a workshop. Insurers ask for a VAT invoice and an engineer report, and you get both at the end.
About Rock itself
Rock is a small locality in County Tyrone, situated inland at an elevation of 99 metres, approximately 18 miles from Armagh. Rock is characterised by its predominantly detached housing stock and is surrounded by nearby places such as Sandholes, Shanmaghery, and Killay. Rock has a population of around 721 residents, making it a relatively small community in the region.
AdBlue drains across County Tyrone, Rock included
AdBlue call-outs in Rock go to teams that serve the towns near it — Sandholes, Shanmaghery plus Killay — and much of County Tyrone further out, throughout BT postcodes. If you're close to a boundary, or somewhere hard to explain, ring and ask instead of assuming.
No towing is needed. In Rock, a small village, a mobile service works: the vehicle is emptied on the spot, be it on a driveway, a side street, a car park or a forecourt.
What AdBlue in a diesel tank costs to put right around Rock
Each job is different, and so not one fixed quote is honest. Three things shift the cost: whether the engine has run and for how long, how much AdBlue went in, and where your car is. That last one turns on whether a technician can get to it safely, and an open driveway is simpler than a tight space behind the far end of the built-up part.
What went in, how much, and whether it ran: every Rock call opens with exactly that, ahead of a quote, never afterwards. The replies turn a range into a straight quote.
Priced on the call before the van sets out, it is paid for that day — card or phone, nothing in advance. Check your insurance whilst we are on the way: many include misfuelling cover.
Rock: still alongside the vehicle?
In that case, do nothing — that is the most helpful move available. Keys out, engine off, ignition off. Phone 0333 366 0103 then tell us it is AdBlue, about how much, and if it has run. Petrol in Diesel takes it from there, around Rock or anywhere across County Tyrone.
