Guns Village: Put Petrol in a Diesel Car?
With your tank still holding the petrol and the motor not yet started, nearly every job requires only a drain, so leave the motor off. That outcome is decided in the minutes right after filling up, rather than by the amount that went in. Throughout Guns Village and the rest of West Midlands, Petrol in Diesel drains the car and cleans it where it sits, whether by a roadside, on a drive or at a forecourt. Phone and then we will show you what comes after that before you attempt anything else.
What now? Petrol in a diesel, in turn
- Feed a petrol motor diesel and it will typically not run at all, and so the motorist stops there and so does the harm. Give a diesel petrol and the engine starts, it ticks over, it pulls away — fine for a couple of miles. Drivers have that backwards, which is the part they get wrong about petrol in a diesel in particular. So don't crank it. And once started, do not rely on it: the fuel system is wearing while you drive.
- Switching your ignition on frequently primes the system, and priming is what draws petrol out of that tank and into your pump and injectors. Those are the components diesel keeps protected on its way through, before it burns. Petrol manages the burning and none of the lubricating. Leave the ignition be.
- Do not add diesel on top to weaken it. A diesel fuel system will not accept petrol by percentage the way that advice implies, and topping up takes out nothing — it merely gives you a fuller tank of the same blend. The type makes no difference either: super unleaded is still petrol.
- Stay where you are if you sensibly can. A vehicle that has not shifted is the quickest one to sort, and we would rather travel to a difficult location than have it started. If you are stopped on the verge on Tyndal Street, switch your hazards on and keep it there.
- Our van arriving instead of circling hinges on two things: a postcode beginning B70 9, and whatever is next to you with a name on it. Get both prepared before you phone.
- Phone 0333 366 0103. Expect three questions — what was put in, about how much, plus whether the motor has been turned over. Those replies shape all that comes after.
Your high-pressure pump spent that morning run labouring on a fluid that had shed a lot of the protection it is designed around. Diesel greases that pump, and your injectors with it, before any of the fuel burns; petrol does the burning and none of the protecting. So imagine a diesel Renault Megane, topped up at quarter past eight, driven in to work, and parked sitting outside Sandwell & Dudley till you realise at about eleven. Three hours of sitting have altered nothing about it. The few miles before that altered plenty, which is why the thing our engineers ask you is about mileage instead of hours. Call us. Leave the vehicle precisely where it stands.
Petrol in your Volkswagen Tiguan, and it takes diesel? Shopping in your boot, you outside Milus Supermarket, somewhere around Guns Village? Then phone, and leave the engine out of it — not even to get out of the bay. Somebody comes out to you. Tank emptied, fuel lines cleaned, new diesel in, and home you go. Easy throttle over a mile draws very little, so these tend to be the straightforward cases.
Normal on the way out, flat on the way back. If that is how the run to Black Country Millennium Forest went, your tank is the place to look. Petrol dilutes diesel, and weaker fuel slips past the tightly fitted parts that are supposed to build injection pressure — so the farther the Audi A4 drove, the less well it held that pressure. Pull in somewhere safe, turn off then phone us.
About as well as this goes, once the engine has turned: away from the pumps, receipt read, and the diesel Ford Focus parked by Farley Memorial Stonework scarcely two streets on. Phone us, and leave the vehicle off. A short hop does really help. It was still a start and still a drive, though, and so the filter and the pump have had weakened fuel through them — hence flushing the fuel lines instead of only draining your tank.
A throttle gone soft, white smoke, an uneven idle, clattering: that's a misfuelled diesel Dacia Duster telling you what is wrong. Do not restart the vehicle to find a better place — turn off where you have stopped, by Farley Clock Tower or anywhere else.
Draining petrol from your diesel at a forecourt
A fair share of this work ends up completed at the pump, since that is where it usually begins. Still at Shell? Then that is normally where it happens. Station forecourts are normal for us, with the permission of the station.
Before your motor has started — the forecourt is the one location it gets caught. Fuel drawn out of that tank and through the fuel filter, all the way to the high-pressure fuel pump, is what happens when the motor is switched on and your car is moved to where it is now: the car park, the drive or the lay-by, everywhere other than the forecourt. So the flush covers the fuel filter and the lines as well as the tank. That's still not a catastrophe, and we deal with it where your car sits. What settles it is whether the ignition was turned in the seconds after your receipt was read.
The staff will normally happily move the vehicle out from the petrol pump so the next customer can get by. It is worth doing. Starting it for four car lengths? Never.
Areas we serve in Guns Village
As a residential suburb, Guns Village gets a routine call, and the villages round about come along on the same journey: Lamberts End and West Bromwich, Swan Village and Lyndon, Mayers Green.
Our technicians still come. Those names above are just the closest neighbours, and a page exists for nearly all towns in West Midlands, so an absence from the list is not an absence from our coverage. Assuming is the thing to avoid, above all on the border or anywhere the satnav fails. Phone and ask.
The map is the area this page includes. We work roadside, at forecourts, on driveways and at car parks over all of that, and your vehicle doesn't need to come to us.
Stranded by the kerb somewhere in Guns Village?
Not everybody gets the chance to stop somewhere safe. Hazards going in a lay-by somewhere, or stopped on the verge of Carters Green as you worked it out after setting off — we take that call often enough that it is the usual kind.
Whether you stay beside the car or move away from it rests on if staying in it seems wise. It will often oblige. A diesel running on petrol limps along very willingly, and that's the problem: fire it up to reach somewhere better and the mixture goes further into the fuel system with every mile driven. However tricky the location, it is no problem for us to come to it, and that's much better for the vehicle than carrying on.
Some miles on petrol in a diesel: now what?
Here is where the M5 matters, under 3 miles out of Guns Village. A drop in power, an uneven idle, some smoke: those are the symptoms when they appear, instead of a clean stop — and a misfilled diesel will usually get you onto it and some way along before anything seems wrong at all.
Never start it to reposition. Come off at the first safe junction then turn off. Presume the worst of that on a long drive. Anything near the under 10 miles to the closest city, and the petrol has been through the filter, through the pump, through your injectors. Mention it when you phone. What our technicians bring alters.

What comes next when our technicians reach you around Guns Village
- Three things get checked before any quote — the fuel that got in, the amount, and whether anything has been run since. Each answer shapes the work.
- Out goes the tainted fuel.
- Lines rinsed, filter cleared. Whatever is left later on is not the thing that created the trouble.
- Our engineers pour fresh diesel in and prime the system.
- Once it is started, our technicians check it runs correctly on fresh diesel.
That has it ready to set off. There's no need for a garage at any stage, because the work is all done where your car is, and when it's spotted early, permanent damage is very unusual.
AdBlue in a diesel tank around Guns Village is a different problem
The issue isn't the same, though the opening rule is — do not crank it — if what got in was AdBlue rather than petrol. The protection a fuel system relies on gets taken away by petrol, which weakens your diesel. AdBlue is urea in water, and in a diesel tank it brings corrosion and residue in its place.
Our technicians deal with both, and AdBlue removal around Guns Village has its own page with the detail — including why it is often the more significant of the two.
Budgeting for a petrol-in-diesel fuel drain around Guns Village
One number would not be fair here, because this is not one job. These are the things that move it:
- Started? Driven? Either answer matters more than anything else on this list.
- The tank's capacity, set against how much of the wrong fuel got into it.
- AdBlue or petrol, whichever went in.
- Access: the vehicle's position, and whether working on it there's sensible for our van.
Tell us what the car is, how much went in, and if the engine has run. A clear answer comes back, not a range. If it's not time-critical — the car is at home and going nowhere — works too.
Guns Village drivers ask us these about petrol in diesel
At a petrol station around Guns Village, can you do a fuel drain there?
Much of what we do gets done nowhere else. So yes. Our engineers attend Tesco and the other forecourts around town all the time, with the site's agreement — tell us which one you are at when you call and we'll tell you whether our engineers can work there.
How much petrol is too much for a diesel?
Litres aren't the yardstick. Proportion is, and far more than either, it matters whether anything has been run. What determines how much work is needed is whether that mix has been sucked through the system — since even though five litres in an almost empty tank is a separate matter from five in a full one, either way that's the query.
Petrol in my diesel, and I have driven the vehicle
Pull over somewhere sensible, turn off, and leave it off. Driving is what shifts the problem from the tank into the pump and injectors — but it is fixable much more often than motorists assume, and the single most valuable thing you can do now isn't restart the vehicle.
My warranty — does a fuel drain void it?
It is not an alteration, and so a drain and flush carried out properly does not cancel a manufacturer's warranty. Another reason to leave it switched off: running a diesel on petrol is the thing likelier to cause an argument with one.
Two-stroke oil in the tank, and then home?
No. It belongs to a distinct fault from a different era, and petrol has thinned something no oil of that kind replaces. Your pump still has to put up with it, since that tank still has petrol in it after that.
Does petrol in a diesel have to go to a main dealer?
There's no need to bring it to a main dealer, since our technicians drain and flush the vehicle wherever it is.
Still with your vehicle?
Turned off is how the car remains.
Already driven it? Then stop somewhere sensible, switch off, and let the car stay that way. Cold and stationary, a car is in the best position available — and drivers fear this a lot more than the recovery rate warrants.
