Wilthorpe: Put Petrol in a Diesel Car?
With your tank still holding the fuel and the engine not yet started, nearly every job takes only a drain, so leave the motor off. That outcome is settled in the minutes immediately after the fill-up, rather than by the amount that went in. Across Wilthorpe and the remainder of South Yorkshire, Petrol in Diesel drains the car and cleans it where it stands, whether by a roadside, on a driveway or at a forecourt. One call to us will be plenty: our technicians can explain what happens after this. Do this first.
Your first five minutes: petrol in a diesel
- Feed a petrol motor diesel and it will normally fail to run at all, and so the person stops there and so does the damage. Feed a diesel petrol and the engine starts, it idles, it moves off — fine for several miles. Motorists have that backwards, which is the bit they get wrong about petrol in a diesel especially. So do not fire it up. And if started, do not rely on it: the fuel system is wearing down as you drive.
- Two things, diesel: it burns, and on the way through it keeps that injection pump and injectors oiled. Petrol only manages the one. Which is why the ignition remains off also — flick it on and you often prime the system, and that's petrol exiting the tank for precisely those parts.
- That guidance presumes a diesel fuel system tolerates petrol by percentage. It doesn't. Add diesel on top and nothing at all is taken out; what you get is a larger tank of the same mixture. And no, the grade makes no difference — super unleaded is still petrol.
- We would rather drive to a difficult place than have it started — so if you reasonably can, sit tight. Nothing is simpler to sort out than a car that has not shifted. On the verge on Redbrook Walk, that means hazards on and keep the vehicle.
- Our van showing up rather than circling depends on two things: a postcode starting S75 2, and whatever is nearest to you with a name on it. Keep both ready before you ring.
- What was put in, approximately how much, plus if the car has run — those three replies shape the entire call-out. Call 0333 366 0103 then tell us.
The run in is what pushed diluted diesel through your pump. Standing still has pulled nothing. Petrol in a diesel Renault Megane, parked outside Barnsley all day, sits harmless in the tank while it waits. Ring us first — before the keys go in.
The complicated part is that bay, not your fuel. Cars either side of you, a trolley shelter behind, and occasionally a height barrier on the way in that settles if a van can reach you at all — so when you ring from a car park like the one at Green Apple Market, mention how much space there's around you and which way round the car is. Those our engineers attend frequently. Should there be no space to work next to your diesel Volkswagen Passat, it gets moved with your engine off, and not out of fussiness over a handful of seconds of running: priming happens at every start, more of that blend leaves your tank for your pump, and two shunts into a roomier bay have gradually made a worse job of what was simply a vehicle sitting still.
Your pump isn't turning, and so whatever your diesel Mercedes C-Class did on the way to Wilthorpe Park, none of it is happening now. Nothing gets worse whilst it stands. Take your time over this — but do not drive the vehicle home to buy any.
Clattering, a lumpy idle, white smoke, a throttle gone limp. That is a misfilled diesel Audi A6 telling you what's wrong. Turn off where you have stopped, near Emmanuel Methodist or anywhere else, and never restart it to find a better place.
By now your tank is the least of it. Run a diesel and that blend goes into the filter, into your lines, into your pump, into the rail — and none of that leaves with the tank contents. A diesel Ford Kuga that made it by Giraffe needs its system cleared. Clearing is not the same thing.
Forecourt drains for petrol in a diesel
A good part of this job gets done at a forecourt, as that's where it often begins. If you're still at the forecourt at Jet, that's typically where the drain gets done — our technicians work on garage forecourts all the time, with the station's permission.
At a forecourt, this gets caught with your motor never started, and nowhere else does that. Fuel sucked out of your tank and through your filter, all the way to the high-pressure pump, is what happens when the motor is fired up and the vehicle is moved to where it is now: the car park, the drive or the lay-by, everywhere other than the forecourt. So the flush takes in the filter and the lines as well as that tank. That's still not a catastrophe, and our technicians sort it out where the car stands. What settles it is whether the ignition was reached for in the seconds after the till receipt was read.
Staff will usually help out pushing it clear of the petrol pump, which lets the next customer get through. Welcome the assistance. Firing it just to roll four car lengths isn't.
Wilthorpe and the villages next to it
Those same rounds get us to Gawber, Old Town, Redbrook, Pogmoor and Honeywell besides Wilthorpe, which is a residential suburb.
Not on this list? It says nothing. The names above are just the closest few, and nearly all towns in South Yorkshire have a page of their own elsewhere on our site. Near a boundary, or somewhere your satnav gets wrong? Contact us and ask instead of presuming.
That map is the area the page covers. All of it is ground we cover: a kerbside, a forecourt, a drive, a car park. You never move the vehicle anywhere.
Stuck at the kerbside near Wilthorpe
Some drivers get no sensible place to pull in whatsoever. A normal call for us instead of a rare one: worked out after setting off, landed on the verge beside Redbrook View or in a lay-by with the hazards flashing.
Safe there? Remain by it. Not safe? Climb out and clear of it. It will often oblige. A diesel running on petrol limps along very willingly, and that is the trouble: fire it up to reach somewhere safer and the mixture goes further into your fuel system with every mile travelled. Our van coming to an inconvenient place is no bother for us, and it's a lot better for the vehicle than driving on.
Driven it already? Pull over, and check below
Your M1 is the one that counts here, and runs under 3 miles from Wilthorpe. A misfilled diesel will usually take you onto it and some way along before anything seems wrong, while the symptoms when they arrive are normally a drop in power, an uneven idle and some smoke instead of a clean stop.
Take the first exit that's safe, pull up there, and don't restart it to move it. Suppose the worst of it on a long run. Anything approaching the under 10 miles to the closest city, and the mixture has been through the fuel filter, through your pump, through your injectors. Tell us when you ring. What we bring alters.

Wilthorpe's setting is characterised by its inland location, with gently rolling hills and valleys surrounding the area.
The visit around Wilthorpe, step by step
- Three things get checked before any quote — your fuel that went in, the quantity, and if anything has been run since. Each answer changes the work.
- Your tank gets cleared of everything.
- Fuel lines are flushed through and the filter cleaned, leaving nothing in the system that caused any of this.
- Bleeding your system follows, once new diesel is in.
- Our technicians fire it up and confirm it runs properly on clean diesel.
At that point it is ready to pull away. All of this is done where your car is, so it never needs to go to a garage, and when it has been caught soon, permanent damage is very uncommon.
AdBlue in the diesel tank instead, around Wilthorpe?
Never start it: that opening instruction stands whether what went in was AdBlue or petrol. What differs is this fault itself. Thinned diesel, and no protection left for your fuel system that depends on it. That is petrol. AdBlue is urea in water, and in a diesel tank it brings rust and residue in its place.
AdBlue removal around Wilthorpe has a page of its own with the full story on it, including why it is frequently the more serious of the two. Our technicians cover both.
What a petrol-in-diesel fuel drain costs in Wilthorpe
What changes the price is listed below, since the job isn't one job and our technicians can't honestly put a single figure on this page.
- Has it been started or driven? Nothing else matters for as much.
- Wrong fuel in, against what that tank holds — that ratio.
- AdBlue or unleaded, whichever was put in.
- Access: the car's position, and whether working on it there's sensible for a van.
A clear answer rather than a range is what you get for telling us three things: the vehicle, the amount, and if it has run. For the car at home that is going nowhere and isn't time-critical, works too.
Wilthorpe drivers ask us these about petrol in diesel
At a petrol station around Wilthorpe, can you do a fuel drain there?
Yes — forecourts are where a good part of this happens. Our engineers work at Gulf and the other forecourts nearby all the time, with the site's consent — tell us which one you're at when you phone and we will tell you whether we can work there.
A few litres of petrol in a diesel — too much?
Whether your engine has run matters much more, though the ratio counts too, rather than the litres. Five litres in a nearly empty tank is a distinct matter from five in a full one — but either way, the thing that determines how much work is required is whether that mix has been pulled through the fuel system.
Petrol in my diesel, and I have driven it
Stop safely. Off. Nothing after that. Driving takes the problem along — out of your tank, into your pump and injectors. People fear it a good deal more than the recovery rate warrants, mind. The one really valuable thing left to you isn't restarting the car.
Will a fuel drain void my warranty?
A drain then flush carried out properly isn't a change and does not cancel a manufacturer's warranty. Running a diesel on petrol is the thing more likely to cause a dispute with one, which is another reason to leave the vehicle turned off.
Adding two-stroke oil, then driving home
Two-stroke oil solves a separate problem, and an old one at that. Nothing it does puts back what petrol diluted. No. The pump still has to cope with it, because the tank still has petrol in it later.
Main dealers and petrol in a diesel
Wherever the vehicle is, our engineers drain and flush it there, so a visit to the main dealer doesn't come into it.
You, and your car, still together?
The motor remains off.
Already driven it? Then pull in somewhere sensible, switch off, and let the car stay that way. Cold, still, going nowhere: that is the best place to be in. Drivers fear this far more than they need to.
