Don't Start It: AdBlue in a Diesel Tank in Olney
If AdBlue has got into the diesel tank, leave your motor off and leave the ignition off. Chemically, AdBlue is just urea in water. It doesn't burn, it does not mix with diesel, and the harm it does begins when the system draws it in. A drain and a thorough flush, done where the vehicle is in Olney, is normally what AdBlue in a diesel tank takes — if it's caught before your engine has run. Before anything, phone us on 0333 366 0103.
Your next steps straight away, Olney: AdBlue in the diesel tank
Do:
- So nobody can switch your ignition on, pull your keys out.
- Near moving traffic? Then put the hazards on.
- The empty bottle or the receipt shows us the product and the amount, and so do not bin it away.
- Call us from where you are. A postcode starting MK46 4, or the name of the closest street, brings our van to you without a search.
Not to do:
- No starting your engine — not for a second, not to reposition your car.
- Many diesels power their fuel pump the moment your ignition comes on, so leave the vehicle off.
- Do not top up with diesel to thin it. AdBlue does not mix in diesel; it separates out.
- Don't drive the vehicle anywhere, not even a short distance along Dartmouth Road.
- Don't try to drain the car yourself at the roadside.
Rolling the vehicle off the island is a job for attendants to help with, whichever Olney forecourt you are on, the Applegreen or any other. If you're on your own drive, leave the car precisely where it sits.
AdBlue in a diesel tank: what it does
Meant for your exhaust, AdBlue has no place in the engine. From a dedicated reservoir it is fed straight to your exhaust, cleaning what the engine lets out. A fuel pump is not designed to take it, and AdBlue was never intended to travel through one.
Tipped in with the diesel, it stays apart instead of mixing — quite unlike fuel. It sinks, because it is denser than diesel, and settles down where the intake takes its fuel from. A motor filled on a driveway in Petsoe End overnight and not started since is the simple one. No pump has sucked the AdBlue up so far — though once the motor runs, that is what goes first, directly from the bottom of your tank.
From there it does two kinds of harm. What is left when the water evaporates is urea, which forms crystals: they settle in narrow channels and clog filters. Worse, it attacks certain metals in the fuel system, and keeps going till it is flushed out. A motor left sitting in Olney with AdBlue already in its lines is worse by the morning; one with AdBlue just in its tank is not. The water in it causes damage of its own: the high-pressure fuel pump and the fuel injectors rely on diesel to lubricate them, and water offers them nothing.
Petrol or AdBlue in a diesel: why AdBlue is often worse
Petrol put into a diesel on Yardley Hastings Garage's forecourt leaves your fuel watery — that is the whole fault. It mixes with the diesel, and whilst it is inside your tank it does no damage; the harm comes from running the engine on it.
With AdBlue in a diesel, the fluid itself is plainly the wrong one. It cannot just be run through, since it does not burn. Crystals and corrosion remain through the following tankful, and AdBlue splits again out of the diesel, so watering it can't work. Hence the flush counts so much, and trying your engine "to see" costs more here than almost any other slip — in Weston Underwood or the heart of Olney equally.
The same good news applies as with petrol. Not run? Then the AdBlue waits just inside your tank, the easiest section of the whole system to empty, wherever the vehicle has come to rest around Buckinghamshire.
Olney: how AdBlue ends up in a diesel tank
After dark, two caps together — the AdBlue one and the diesel one, now and then behind one flap — may look the same. No one intends it; many designs invite it. It usually takes place at home, from a bottle bought en route home, not at the forecourt.
The ways it takes place are few and familiar. Midway through the drop-off, the dashboard warns, and outside Olney Middle School the refill is hurried. A driver tips the bottle in outside their house, right off Holes Lane, as the day ends. Another pattern: dim light, a pub car park by The Two Brewers, and someone opening that flap the first time.
Rented vehicles, new vehicles, company cars, or the second car in a family with both fuels: the least known cars see it most. Same slip, an identical first response — leave it off — wherever you are around Olney or the rest of Buckinghamshire.
Already started your engine with AdBlue in the diesel tank in Olney?
The AdBlue has left your tank, then. It has been sucked through your filter and the fuel lines, and if the engine ran for any time, it has reached the high-pressure fuel pump and the fuel injectors.
Maybe returning from The Recreation Grounds, or part way across Olney, the engine may go lumpy, smoke, drop power, flash your dash or cut out. Stop as soon as it is safe, switch off, and do not restart it to check. With each start, more of that is pulled through.
Olney sits under 5 miles from the M1; if you were on it, leave by the next junction and stop somewhere safe rather than carrying on.
How far it went counts. A couple of hundred yards across Olney to the car park by Olney Library is a very different job from a run towards Milton Keynes, under 10 miles away, with the AdBlue reaching further into your system with every mile. Tell us about how far it had come.
Once the motor has run, the flush includes more, and all of it is done where the vehicle has come to a stop. Very seldom does it leave long-term damage if it's caught early.
What does an AdBlue drain on a diesel involve in Olney?
Our engineers come to the vehicle, wherever it has stopped in Olney: a side street close to The Olney Centre, a drive, a lay-by or a forecourt. The work depends on three replies, which we ask for first — which fluid went in, the amount, and if your motor has turned over.
Right there, your tank is then drained, and all of the contaminated diesel and the urea leave as one. With AdBlue, more so than with petrol, the flush counts: the fuel system is cleaned right through because what remains will not wash out by itself. The fuel filter is cleaned, or replaced where it needs to be; fresh diesel goes in; and the car is tested. Most of these jobs are a half-hour job once our technicians get there, if your engine hasn't run. Explosion-proof pumps mean a busy forecourt safe to work on, and they're quiet enough to spare the street at night.
Finally, the fuel system is bled with new diesel. You set off as soon as our technicians have started the car, and it makes no difference whether your car is on a driveway in Olney or in a space outside Wolverton. The test before our engineers leave is that it runs smoothly on new diesel. Our engineers do it all wherever the car has ended up, and it never has to be taken to a garage. Insurers want a VAT invoice and an engineer report, and you get both at the end.
About Olney
Olney is a small town in north Buckinghamshire, situated on the banks of the River Great Ouse at an elevation of around 53 metres. Olney sits near the border with Bedfordshire, close to the larger town of Milton Keynes, and is surrounded by smaller villages such as Clifton Reynes and Emberton. Olney has a population of approximately 6600 people, predominantly living in detached houses. Olney is located about 51 miles northwest of London, making it a commuter town for some residents.
AdBlue drains across Olney and Buckinghamshire
Our vans that answer AdBlue call-outs in Olney also cover the spots round it, Clifton Reynes, Warrington and Emberton among them, and most of Buckinghamshire beyond, across the MK postcode area. If you're close to a border, or somewhere hard to describe, ring and ask instead of guessing.
No moving is needed. In Olney, a riverside town, a mobile service fits: your vehicle is drained on the spot, be it on a driveway, a residential street, a parking area or a filling station.
What AdBlue in a diesel tank costs to put right in Olney
No single price would be honest, since every job differs. Three things move the cost: whether the motor has been running and for how long, how much AdBlue got in, and where the car is. That last one rests on whether our van can reach it safely, and an open drive is simpler than a tight spot behind Our Lady Help of Christians and St. Lawrence.
Before a figure, never afterwards, every enquiry from Olney opens with the same three checks: the fuel, the amount, plus if the engine ran. With those replies, a range narrows to a single firm number.
Before a van heads out, you hear our quote by phone. Then payment is on the day, by card or over the phone, with nothing upfront. While our engineer is on the way, check your policy: plenty cover misfuelling.
Olney: still alongside your car?
Then, do nothing — that's the best move available. Engine off, keys out, ignition off. Tell us it was AdBlue, about what quantity, and whether the engine ran, on 0333 366 0103. After that Petrol in Diesel takes over, across Olney or anywhere in Buckinghamshire.
