Charfield Green: Put Petrol in a Diesel Car?
Petrol in Diesel drains and cleans wrongly fuelled vehicles where they sit, on the forecourt, at the roadside or on a driveway, across Charfield Green and the rest of Gloucestershire. The first thing to do is not to turn on the motor. When your engine has not yet run and the fuel is still inside the tank, a tank drain is nearly always all it requires, and the following few minutes settle that, not how much was put in. Contact us and then we can explain what follows after that before you attempt any more.
The first five minutes: petrol in a diesel
- While you drive, your pump and the injectors wear down. This is why you never fire it up, and why you do not believe it once it has started. The catch about petrol in a diesel in particular — the bit people get wrong — is that it pulls away happily for the first mile or two. Diesel in a petrol motor usually can't run at all, which stops the motorist and stops the harm with them. This one lets you drive on.
- Two things, diesel: it burns, and on the way through it keeps the high-pressure pump and injectors protected. Petrol only handles the one. Which is why the ignition is left off too — flick it on and you usually prime your system, and that's petrol leaving that tank for just those parts.
- Topping up clears nothing. It hands you a bigger tank of the same mixture, since a diesel fuel system will not cope with petrol by percentage in the way that advice presumes — so don't pour diesel on top to dilute it. Grade is irrelevant too: super unleaded is petrol.
- A vehicle that hasn't shifted is the simplest one to deal with, and so remain where you are if you sensibly can. Parked on the verge on Kings Meadow? Hazards on, then keep the vehicle there. An odd location works for us better than a started motor.
- Get your location prepared before you ring. A postcode beginning GL12 8 and whatever is next to you with a sign on it is the difference between a van turning up and a van circling.
- Dial 0333 366 0103. Prepare for three questions — what got in, roughly how much, and if the motor has been run. Those responses decide everything that comes after.
Quarter past eight. A hurried fill-up on the drive in. At about eleven it dawns on you, and by then the diesel Volkswagen Golf has stood outside Cam & Dursley for three hours. Phone us and leave the car where it stands. What matters is the journey in, as diesel both burns and — before that — greases your pump and your injectors, whereas petrol only ever burns. Those few miles ran your pump on a fuel stripped of much of its protection, and no volume of standing in a car park gives any of it back. Hence the thing we ask about miles rather than hours sitting, and hence the request to leave the keys be till our technicians arrive.
The difficult part is the bay, not your fuel. Cars either side of you, a trolley shelter behind, and from time to time a height bar on the way in that decides if a technician can reach you at all — so when you phone from a car park like the one at Co-op Food, mention how much room there is about you and which way round your car is. Those our technicians attend often. Should there be no room to work next to the diesel Renault Clio, it gets rolled with the motor off, and not out of pedantry over a couple of seconds of running: priming occurs at every start, more of the mixture departs the tank for the pump, and two shunts into a better space have silently made a harder job of what was just a vehicle standing still.
Sitting still, it gets no worse. Your pump is not turning, so whatever occurred on the way to Tortworth Copse in that diesel BMW 5 Series is finished happening. Time is yours. Just don't take it home on the engine to find more of that.
Why we're direct about not driving on: your pump waits upstream of the fuel injectors, so whatever a worn pump gives off travels downstream with the fuel. Leave the Kia Sportage close to Charfield Christian Centre then ring us.
The filter, the lines, the pump and its rail: that is where the mixture is once a diesel has run, and it doesn't come back out with your tank contents. So your tank isn't where most of the problem waits by this point, and a diesel Audi Q3 that got close to St John needs your system cleared instead of drained.
Pump-side draining for petrol in a diesel
Forecourts are where the work often kicks off, and where a fair share of that ends. Still at Gulf? Then that is generally where it happens. Station forecourts are everyday for us, with the consent of the owner.
No place except a garage can the mistake be halted with the motor still unstarted. Anywhere else — a car park, a driveway, a lay-by — the car was switched on and moved to get there, which means fuel was sucked from the tank, through the fuel filter then into your high-pressure pump. That is not a catastrophe, and we can still sort it out where it stands. It does mean your lines and your filter need flushing as well as your tank, and that's determined by the few seconds between checking your receipt and going for the keys.
Away from the petrol pump, the next driver can get past — so yes, let the staff help you move the car. Very much worth it. Starting the car just to shift four vehicle lengths is not.
Will we serve your end of Charfield Green?
These same trips bring us to Charfield, Little Bristol, Charfield Hill, Churchend and Huntingford besides Charfield Green, which is a residential suburb.
There are dedicated pages for most towns in Gloucestershire, and the ones named above are just the closest neighbours — so yours being absent from the list tells you nothing whatsoever about if our engineers come. Assuming is the thing to skip, especially on the boundary or somewhere your phone struggles. Ring us to check.
Use the map for the area included here. Kerbside, forecourt, drive, car park: every bit of that is territory we cover, and none of that requires the car to come to us.
Charfield Green: stranded where you stopped
Not everybody has the chance to pull over anywhere safe. If you noticed after setting off and landed along the verge of Elbury View, or in a lay-by somewhere with the hazards on, that's a routine call for us instead of an unusual one.
Safe where you are? Sit beside it. Not safe? Get out and clear of it. It will frequently oblige. A diesel running on petrol limps along very willingly, and that is the trouble: fire it up to get to somewhere better and that blend goes further into your fuel system with every mile driven. Pressing on causes the car far more harm than our van heading out to a difficult location, and that is no problem for us.
Petrol in a diesel, but your car has travelled
under 3 miles out of Charfield Green, your M5 is what matters here. A misfuelled diesel will usually get you onto it and some way along before anything feels wrong, while the symptoms when they arrive are typically lost power, a rough idle and some smoke rather than a tidy stop.
Take the next junction that's safe, stop there, and do not start the vehicle to reposition. On a longer run — anything near the under 25 miles to the closest city — assume the contamination has been through the fuel filter, your pump and the injectors, and tell us when you call. It changes what we bring.

Our job in Charfield Green, step by step
- The answers alter the work, which is why our engineers ask before giving a price: what went in, how much of that, and whether the engine has run.
- That tank is emptied completely.
- Fuel lines are purged through and your filter cleaned, leaving nothing in your system that created any of this.
- Our technicians put new diesel in and prime your system.
- When it is fired up, our technicians confirm it runs properly on new diesel.
At that point it's ready to drive away. Lasting damage is very unusual when it has been noticed early, and because all of this is done where the vehicle is, it never needs to be taken to a workshop.
AdBlue in a diesel tank around Charfield Green is a distinct matter
If what went in was AdBlue rather than petrol, the first rule is unchanged — never start the car — yet this fault isn't. Petrol does two things to diesel: thins it, and strips out the protection the fuel system relies on. AdBlue is urea in water, and in a diesel tank it causes corrosion and build-up in its place.
AdBlue removal in Charfield Green has a page of its own with the detail on it, including why it's usually the more serious of the two. We cover both.
How much is a petrol-in-diesel fuel drain around Charfield Green?
One price would not be honest here, since this isn't one job. These are the things that move it:
- Started? Driven? Either answer counts more than anything else on this list.
- Wrong fuel in, against what your tank takes — that ratio.
- AdBlue or petrol, whichever was put in.
- Where is it? And can a van reach it and work there sensibly?
The vehicle, the quantity, whether it has run — give us those and the answer comes back straight instead of as a range. Not urgent, with your car at home and going nowhere? Then is fine.
Petrol in diesel questions from Charfield Green drivers
At a petrol station around Charfield Green, can you do a fuel drain there?
Yes — forecourts are where a large part of this takes place. Tell us which one you're at when you call and we will tell you whether we can work there. With the owner's consent our technicians visit Shell and the other forecourts around town regularly.
How much petrol in a diesel is too much?
Ratio decides it instead of litres — and more than either, whether the motor has run. An almost empty tank with five litres in it, against a full one with the same five: distinct scenarios, of course. Either way, the work required comes down to one thing, which is if the system has had that blend pulled through it.
I drove the car after putting petrol in my diesel. Now what?
Turn off somewhere safe, then keep it that way after you stop. It's salvageable a lot more often than drivers fear, even though driving is what shifts the problem from that tank into the pump and injectors — and the single most helpful thing you can do now isn't restart it.
My warranty — does a fuel drain void it?
A drain then flush carried out correctly isn't a change and doesn't invalidate a manufacturer's warranty. Another reason to leave it switched off: running a diesel on petrol is the thing more likely to cause an argument with one.
Two-stroke oil in your tank, and then home?
No. It belongs to a distinct issue from a different era, and petrol has diluted something no oil of that kind puts back. Your pump still has to cope with it, since your tank still has petrol in it later on.
A main dealer for petrol in a diesel — essential?
You don't need one. The vehicle is drained and flushed wherever it is, with no need to take it to a main dealer.
You, and your car, still together?
Do not switch the car on again.
Driven it already? Then somewhere sensible, stop, turn off, and no restarting the car afterwards. Cold, parked, going nowhere: that's the best place to be in. People fear this a lot more than they need to.
