Hellaby: Put Petrol in a Diesel Car?
With your tank still holding the petrol and the motor not yet run, almost every job takes only a drain, so keep the engine off. That result is decided in the minutes straight after the fill-up, and not by the amount that was put in. Across Hellaby and the remainder of South Yorkshire, Petrol in Diesel drains the vehicle and cleans it where it stands, whether by a roadside, on a driveway or at a forecourt. Just one ring our way is sufficient: our team will show you what follows after this. Make it straight away.
The next five steps: petrol in a diesel
- While you drive, the pump and your injectors wear. This is why you never fire it up, and why you never rely on it once it has started. The catch about petrol in a diesel in particular — the bit motorists get wrong — is that it drives away happily for the first mile or two. Diesel in a petrol engine usually can't run at all, which stops the motorist and stops the damage with them. This one lets you drive on.
- Flicking the car's ignition on often primes your system, and priming is what moves petrol out of that tank then into the pump and injectors. Those are the components diesel keeps lubricated on its way through, before it burns. Petrol does the burning and none of the oiling. Leave the ignition off.
- Don't thin it. Diesel poured on top removes nothing, and so all you get is more of what was already there, since percentage is not how a diesel fuel system accepts petrol. Super unleaded? Simply petrol. The type makes no difference.
- A car that has not shifted is the simplest one to sort out, and so stay where you are if you safely can. Pulled up on the verge on Old Hellaby Lane? Hazards on, and keep the vehicle there. An odd place works for us better than a started engine.
- A van arriving instead of circling depends on two things: a postcode beginning S66 8, and whatever is closest to you with a sign on it. Have both ready before you ring.
- Call 0333 366 0103. Anticipate three questions — what went in, about how much, and if the car has been started. Those replies shape all that comes after.
Quarter past eight. A rushed refuel on the way in. Somewhere around eleven it occurs to you, and by then your diesel Volkswagen Golf has sat outside Conisbrough for three hours. Phone and leave the vehicle where it sits. What is key is the journey in, as diesel both ignites and — before that — protects the pump and the injectors, while petrol only ever burns. Those few miles ran the pump on a fuel stripped of most of its protection, and no volume of standing in a car park gives any of that back. Hence the question about miles instead of hours standing, and hence the instruction to leave your keys alone until our engineers get there.
Car parks like the one outside Morrisons are a spot our technicians visit often, and your fuel is rarely the difficult part. The bay is: vehicles either side, a trolley shelter behind, occasionally a height barrier on the way in that settles if a van can access you at all. So tell us how boxed in you are when you ring, and which way the car is facing. If we can't work beside the diesel Renault Megane we'll roll the vehicle without running it — and that is not fussiness about a couple of seconds of running. Every start primes the fuel system and draws more of that mixture out of the tank and on to the pump, and so a motor shunted twice into a nicer space has quietly become a worse job than one left exactly where it stopped.
Your Peugeot 308 stays where it is in the car park at Sir Jack's for the whole job, which typically goes like this. First we ask what went in, roughly how much, and whether the motor has run since, because much of the work rests on those replies. The tank is emptied of the polluted mixture, the lines are flushed, and the filter comes off if it's a replaceable one. With fresh diesel in and your system primed, the car is started and checked, and once it is running correctly you drive away.
Do not drive it home to buy yourself time. You already have it: nothing gets worse whilst your car sits, because a diesel Dacia Duster left outside Bill Hawes Recreation Ground is doing none of what it did on the way there. The pump has stopped turning.
Three things help when you ring from near East Pennine Assembly Hall Of Jehovah's Witnesses: which side the filler is on, whether a van can park next to without blocking the road, and whether the motor has run since you filled up. On-street is the commonest location our technicians work, and so the place itself is hardly ever the trouble — we would far rather deal with a tight parking spot than with a car that has been driven to somewhere more convenient. We will drain the Ford Kuga, change the fuel filter where there is a usable one, flush the lines then put clean fuel through the whole system, as by this point the worst of it is waiting in the fuel lines instead of in the tank.
Clearing petrol from a diesel on a forecourt
The work kicks off at a pump, mostly. Quite often it ends at one too. Still at Shell? Then that's normally where it happens. Garage forecourts are everyday for us, with the permission of the site.
Before the motor has fired — a forecourt is the one spot this is halted. Anywhere else — a car park, a driveway, a lay-by — the car was fired up and moved to get there, which means fuel was drawn from the tank, through the filter then into your high-pressure pump. That is not a disaster, and we can still put it right where it is. It does mean the lines and your filter need cleaning as well as the tank, and that is determined by the few seconds between seeing your receipt and going for the key.
Staff will usually help out pushing it clear of the petrol pump, which lets the next motorist get by. Welcome the offer. Four vehicle lengths is not worth the risk.
Hellaby and the towns beside it
Bramley Lings, Little Hay Nooking, Hooton Levitt, Bramley, Carr — each of them on our journeys that bring us over to Hellaby too, a village.
If yours is not on that list it doesn't mean we don't come — there are dedicated pages for the majority of towns in South Yorkshire, and the ones listed above are just the nearest neighbours. Guessing is the mistake to skip, especially on a boundary or somewhere the satnav goes wrong. Contact us and enquire.
This map shows the ground the page covers. Kerbside, forecourt, private drive, car park: all of it is ground our technicians cover, and none of it needs your car to come to us.
Roadside breakdowns around Hellaby
Not everyone gets the opportunity to stop somewhere safe. Hazards going at a lay-by somewhere, or stopped on the verge on Bawtry Road since you noticed after setting off — we take that call regularly enough that it's the usual kind.
Sit by your car while it is sensible to wait there, yet out of it when it isn't. Never fire up the engine to nurse the vehicle somewhere safer — a diesel running on petrol will usually oblige, and every mile it obliges for is drawing that mix further into the system. However inconvenient the place, it is no problem for us to get to it, and that is much better for the vehicle than driving on.
A couple of miles on petrol in a diesel: what now?
Your M18 is the road that counts here, and it lies under a mile from Hellaby. Lost power, a rough idle, some smoke: those are the signs when they arrive, rather than a tidy stop — and a misfilled diesel will frequently take you onto it and some distance along before anything seems wrong at all.
The next sensible junction is the one to take. Turn off there, then leave the restarting alone. Assume the worst of that on a long run. Anything approaching the under 10 miles to the nearest city, and the mixture has been through the filter, through your pump, through the injectors. Say so when you phone. What our engineers bring alters.
A bit about Hellaby
Hellaby is a small village in South Yorkshire, situated on the riverside at an elevation of around 105 metres. Hellaby lies approximately 8 miles from Doncaster and 140 miles from London, with nearby places including Bramley Lings and Little Hay Nooking. Hellaby has a population of around 782 people, predominantly living in semi-detached housing.
What comes next when our technicians arrive with you around Hellaby
- We check what got in, how much, and whether the motor has run. The responses shape the work, which is why our engineers ask before quoting.
- Your tank is emptied of it.
- Lines rinsed, filter cleared. Whatever is left later on isn't the thing that started the problem.
- The system gets primed, on fresh diesel.
- The engine is started and tested to be sure it runs correctly on clean diesel.
After that it's ready to set off. Everything is done where the vehicle is, so it never has to go to a garage, and when it has been noticed early, long-term damage is very unusual.
A separate problem: AdBlue in a diesel tank in Hellaby
Never crank it: that opening instruction applies whether what was put in was AdBlue or petrol. What differs is the problem itself. The lubrication a fuel system relies on is taken away by petrol, which weakens your diesel. AdBlue is urea in water, and in a diesel tank it brings corrosion and deposits in its place.
Both are ours. There's a separate Hellaby page for AdBlue removal, with the detail on it — including the reasons it frequently turns out to be the worse of the two.
Budgeting for a petrol-in-diesel drain around Hellaby
What changes the price is laid out below, since the job isn't one job and our engineers cannot truthfully put a single number on this page.
- Started? Driven? Either answer matters more than anything else on this list.
- The tank's capacity, set against how much of the wrong fuel went into it.
- Whether it was unleaded or AdBlue.
- Access: the car's position, and if working on it there's sensible for a technician.
Tell us the vehicle, the amount and whether it has run, and you will get a straight answer rather than a range. Not urgent, with the vehicle at home and going nowhere? Then works.
Hellaby motorists ask us these about petrol in diesel
At a petrol station in Hellaby, can you do a fuel drain there?
Yes — forecourts are where a large share of this takes place. Tell us which one you're at when you ring and we'll tell you if we can work there. With the station's consent our technicians attend Morrisons and the other forecourts around town all the time.
How much petrol is too much for a diesel?
Whether your motor has run counts a lot more, though the proportion matters too, rather than the litres. Five litres in a nearly empty tank is a distinct situation from five in a full one — but either way, the thing that decides how much work is required is if that mixture has been drawn through your fuel system.
I put petrol in my diesel and drove the car. What now?
Turn off somewhere sensible, then keep it that way after you stop. Not restarting it is the single most helpful thing available to you now. Driving does move the trouble out of the tank then into the pump and injectors, yes, and it stays salvageable far more frequently than drivers fear.
Fuel drains and manufacturer warranties
A drain and flush carried out properly isn't an alteration and does not invalidate a manufacturer's warranty. Another reason to leave it turned off: running a diesel on petrol is the thing likelier to cause a disagreement with one.
Adding two-stroke oil, then driving home
What petrol has thinned is not restored by two-stroke oil, which is an old remedy for a distinct fault. So no. Your tank still has petrol in it later on, and your pump still has to cope with it.
A main dealer for petrol in a diesel — necessary?
Wherever the car is, our engineers drain and clean it there, so a drive to the main dealer does not come into it.
Is the vehicle still with you?
Your engine stays off.
Driven it already? Then somewhere safe, stop, switch off, and no restarting the vehicle later. A stationary, cold vehicle is the best place to be in, and this is recoverable from a lot more regularly than drivers fear.
