Put Petrol in a Diesel Car in Spoonley? Don't Start It
If you have not started your engine yet, do not. A fuel drain and nothing else is nearly always what a motor requires while the fuel is still inside your tank and the motor has not yet turned over, which is why it is the coming few minutes that matter, not how much was put in. Petrol in Diesel comes to the car wherever it has come to rest in Spoonley or the rest of Shropshire, on the forecourt, by the roadside or on a private drive, and drains and flushes it there. Call us so we shall tell you what comes next before you do anything else.
Your first five steps: petrol in a diesel
- Give a petrol motor diesel and it will normally refuse to run at all, and so the person stops there and so does the damage. Feed a diesel petrol and the car starts, it idles, it pulls away — all right for several miles. Most people have that muddled, which is the bit they get wrong about petrol in a diesel specifically. So never fire it up. And having started, do not depend on it: that fuel system is wearing down as you drive.
- Leave the ignition be also. Diesel does two jobs: it combusts, and before it burns it lubricates your high-pressure pump and its injectors. Petrol handles the first and not the second. Turning the car's ignition on is often all it takes to prime that system, which moves the petrol out of the tank then into precisely those parts.
- Topping up takes out nothing. It leaves you a bigger tank of the same blend, since a diesel fuel system won't cope with petrol by percentage as that guidance suggests — so never pour diesel on top to dilute it. Grade is irrelevant too: super unleaded is petrol.
- We'd rather get to a difficult spot than have it started — so if you reasonably can, stay still. Nothing is easier to deal with than a vehicle that hasn't moved. On the verge on Adderley Road, that means hazards on then keep the car.
- The van showing up rather than circling rests on two things: a postcode that starts TF9 3, and whatever is closest to you with a name on it. Keep both prepared before you ring.
- Ring 0333 366 0103. Anticipate three things — what was put in, roughly how much, and if your car has been turned over. Your replies shape all that happens next.
Draining petrol from your diesel at a forecourt
A fair share of the job gets finished at the pump, since that is where it usually starts. The drain usually happens right there. Still on the forecourt at Morrisons? Given the station's consent, that's a place our engineers work, and regularly.
No place other than a forecourt can it be spotted with your motor still unstarted. The few seconds between reading the till receipt and going for your key determine how much requires rinsing. Anywhere other than the forecourt — a car park, a drive, a lay-by — the car was fired up and driven to get there, so fuel was sucked from your tank, through the filter then into your high-pressure pump. That means your lines and the fuel filter need cleaning as well as the tank. It is not a catastrophe, and we can still sort it out where the vehicle sits.
Away from the petrol pump, the next motorist can get through — so yes, let the staff help you move it. Worth it. Firing it over four car lengths? Don't.
Petrol in the Peugeot 308, and it takes diesel? Shopping in the boot, you outside ALDI, somewhere around Spoonley? Then call us, and leave the engine out of it — not even to leave that space. A technician comes out to you. Tank emptied, fuel lines purged, clean diesel in, and home you go. Light throttle over a mile draws little, and so these are usually the simple ones.
Hazards on. Ignition off. Phone. It's twenty to nine by Market Drayton Junior School, you're late, and your receipt says unleaded — and although three miles in the Nissan Qashqai feels like nothing, fuel is supplied on demand, and a hurried drive needs plenty of it.
Diesel has to be viscous enough to seal the tightly fitted components it runs through, and petrol dilutes it. That's the whole process, and it accounts for the usual The Rookery call: a diesel Mercedes C-Class that travelled out there without a murmur and came back down on power, rough at idle, perhaps smoking a little. A diesel injection system works hydraulically as well as chemically — it requires your fuel to hold pressure, not only to burn — so when the fuel dilutes, pressure that should build and stay built starts bleeding past clearances instead, and the engine gets a weaker, later, less even delivery than it was engineered round. No part of that is your engine failing, which is the part worth hearing: it's the fuel no longer behaving like diesel, and it stops when the fuel is corrected.
Leave the Dacia Duster close to Beacon Community Centre and ring us. We are direct about not driving on as a worn-out pump sheds, and what it gives off passes downstream with the fuel to your injectors further along.
Hire car or company car? Phone them before you phone us — some agreements want the hire firm to sign off the work, and sorting that out first is a great deal quicker than sorting it later. Then phone us about the Audi A3 close to Market Drayton Library, and do not worry that you cannot say how full the tank was. Almost nobody can, in a vehicle they collected two days ago, and our technicians work it out there. The reason we ask is that petrol in a diesel does its damage as a share: the same few litres in a nearly empty tank is a far stronger blend than in a full one. Petrol is rated on how well it resists igniting under pressure, which is the opposite of what a diesel needs — so the stronger the mixture, the more it knocks, smokes and goes flat.
Spoonley plus the towns next to it
The same rounds take us to Longslow, Styche Hall, Greenfields, Little Drayton and Brownhills besides Spoonley, which is a rural hamlet.
There are separate pages for nearly all locations around Shropshire, and the ones mentioned above are simply the immediate neighbours — so yours being left off the list tells you nothing whatsoever about whether we come. Guessing is the mistake to resist, particularly on a border or anywhere the satnav goes wrong. Call us and ask.
That map is the ground this page includes. The car doesn't need to travel to us. We work throughout every bit of that — kerbside, forecourts, driveways, car parks.
Stuck at the kerbside in Spoonley
Not everybody has a chance to pull in somewhere sensible. A common call for us rather than an unusual one: realised after setting off, finished up by the verge of Duckow Close or at a lay-by with the hazard lights going.
Whether you sit beside the motor or move clear of it depends on if sitting there feels sensible. It will frequently oblige. A diesel running on petrol limps along very willingly, and that is the problem: fire it up to reach somewhere handier and that blend goes further into your fuel system with every mile driven. However difficult the spot, it is no trouble for us to get to it, and that's much better for the vehicle than driving on.
Run it already? Pull over, then see this
This is where the M6 comes in — under 10 miles away from Spoonley. It will usually get you onto it, and some way along, before you spot a thing. Then it is smoke, a rough idle and power draining away — not a clean stop. Misfilled diesels rarely give you one of those.
Come off at the next safe junction, turn off, and do not restart it to move it. Long trip? Anything near the under 25 miles to the closest city and you should suppose the lot — filter, pump, injectors, all of that got to by the petrol. Say that on the call, as it changes what goes in the van.
Spoonley itself
Spoonley is a small hamlet in Shropshire, situated inland at an elevation of 83 metres, with detached housing being the predominant type of accommodation. Spoonley lies near the villages of Longslow and Greenfields, and is close to Styche Hall, in a rural area of the West Midlands. Spoonley is approximately 15.6 miles from Stoke-on-Trent and 140.3 miles from London. Spoonley has a population of around 528 people, living in a quiet, rural setting.
What follows when our engineers arrive with you in Spoonley
- The responses change the work, which is why our technicians ask before quoting: what went in, how much of it, and if the motor has run.
- Away goes the polluted mixture.
- Lines purged, filter cleaned. Whatever is left later on is not the thing that created the trouble.
- Fresh diesel goes in, and then the fuel system gets bled.
- It is run with new diesel in it, and our engineers make sure that it's running smoothly.
That leaves your car ready to set off. There is no need for a workshop at any stage, because the work is all done where the car is, and when it is spotted quickly, permanent damage is very uncommon.
A different problem: AdBlue in a diesel tank around Spoonley
Never crank it: that first step holds whether what went in was AdBlue or petrol. What differs is the issue itself. The lubrication a fuel system relies on is stripped away by petrol, which dilutes your diesel. AdBlue? Urea dissolved in water. Tip that in with your diesel and you get corrosion instead, plus residue.
Both are ours. There's a separate Spoonley page for AdBlue removal, with the full story on it — including the reasons it usually turns out to be the worse of the two.
What a petrol-in-diesel fuel drain costs in Spoonley
Frankly, no single figure fits on a page like this. The job varies. Here's what changes it:
- Whether your engine has been run or driven. This is the key one.
- Wrong fuel in, against what the tank holds — that ratio.
- AdBlue or petrol, whichever got in.
- Access: the car's position, and whether working on it there's sensible for a technician.
The vehicle, the quantity, whether it has run — give us those and the answer comes back clear and not as a range. Vehicle at home, going nowhere, nothing time-critical about it — is good for that.
Things our engineers get about petrol in diesel in Spoonley
Fuel drains on a Spoonley petrol station forecourt
A fair share of this work takes place there, so yes. Often, provided the site agrees: Shell, plus every other forecourt nearby. Say on the phone where exactly you have stopped. Whether our engineers can work in that spot is something our technicians answer there and then.
How much petrol is too much for a diesel?
Proportion settles it instead of litres — and more than either, whether the motor has run. Five litres into a nearly dry tank isn't five into a full one, no. But both land on the same question in the end: has that mix been drawn right through, or has it not?
I put petrol in my diesel and drove it. Now what?
Stop sensibly. Off. Nothing after that. It is recoverable far more regularly than people expect, even though driving is what takes the trouble from your tank into your pump and injectors — and the single most helpful thing you can do now isn't restart it.
Will a fuel drain void my warranty?
It isn't a modification, so a drain then flush carried out properly doesn't void a manufacturer's warranty. Running a diesel on petrol is the thing more likely to cause a disagreement with one, which is another good reason to leave the vehicle turned off.
Can I just add two-stroke oil and drive home?
No. It belongs to a different problem from a bygone era, and petrol has thinned something no oil of that kind replaces. Your pump still has to put up with it, because that tank still has petrol in it afterwards.
Do I need a main dealer for petrol in a diesel?
You do not need one. Your car is drained and flushed wherever it is, with no need to bring it to a main dealer.
Is your car still with you?
Shut off is the way it stays.
If you have already driven the car, stop somewhere sensible, switch it off then leave it off. A parked, cold vehicle is the best place to be in, and this is recoverable from a lot more often than people assume.
Throughout Shropshire and in Spoonley: on-site fuel draining, at home or on the forecourt or at the kerbside.
