Put Petrol in a Diesel Car in Burton Hill?
With that tank still holding the petrol and the engine not yet run, nearly every job needs only a drain, so leave the motor off. That result is settled in the minutes straight after filling up, rather than by the amount that was put in. Throughout Burton Hill and the rest of Wiltshire, Petrol in Diesel drains your car and cleans it where it is, whether by a roadside, on a drive or at a forecourt. Our engineers shall explain what the following step will be. Call us — it goes before anything else.
Petrol in a diesel: what to do next
- As you drive, your pump and the injectors suffer. This is why you don't fire it up, and why you do not rely on it once it has started. The thing about petrol in a diesel especially — the bit people get wrong — is that it drives away normally for the first mile or two. Diesel in a petrol motor normally can't run at all, which stops the driver and stops the wear with them. This one lets you keep going.
- Diesel ignites, and before it burns it lubricates — the injection pump, its injectors. Petrol does only the burning. So leave the ignition alone as well: flicking it on is usually all it takes to prime the system, and priming draws petrol from that tank into just those components.
- Never put diesel on top to weaken it. A diesel fuel system doesn't cope with petrol by percentage the way that guidance assumes, and topping up gets rid of nothing — it merely gives you a bigger tank of the same mixture. The grade makes no difference either: super unleaded is simply petrol.
- Stay still if it is wise to. Hazards on, engine off, keep the car. Wherever you have stopped — the verge on Hillcrest, anywhere — an awkward spot for us trumps a started engine, and nothing is simpler for us to sort out than a vehicle that never shifted.
- Before you call, gather your location. Anything nearest to you with a name on it, plus a postcode that starts SN16 9 — that is what settles whether the technician arrives or circles.
- Phone 0333 366 0103. Let us know what was put in, approximately how many litres, and also whether the engine has fired. Those three answers determine the whole job.
Can petrol be pumped from a diesel at a forecourt?
Much of the work starts at a forecourt, so a big part of that gets done there. The drain normally happens right there. Still on the forecourt at Texaco? Given the station's agreement, that's a spot our engineers work, and routinely.
At a garage, it is stopped with the engine never fired, and nowhere else manages it. Everywhere else — a car park, a drive, a lay-by — the car was fired up and driven to get there, which means fuel was drawn from the tank, through the fuel filter and into the high-pressure pump. That is not a calamity, and our engineers can still deal with it where it stands. It does mean your lines and your filter need flushing as well as the tank, and that's settled by the few seconds between checking the receipt and going for the key.
Away from the pump, the next driver can get through — so yes, let the attendants help you push the car. Worth it. Shifting the car four lengths does not justify cranking the motor.
Areas our vans cover near Burton Hill
Burton Hill is a residential suburb, and we head out to it and to the villages by it on the same rounds: Malmesbury, Milbourne, Lea, Filands and Corston.
Not on the list? It means nothing. The places above are simply the closest few, and most towns across Wiltshire have a page of their own elsewhere on our site. Assuming is the mistake to skip, especially on a boundary or anywhere the satnav goes wrong. Contact us and enquire.
The area this page includes appears on the map. Our technicians work by the road, on forecourts, on driveways and at car parks across all of it, and your vehicle does not need to move to us.
Nothing warns you, since from behind the wheel there's nothing to be warned about. The diesel Audi A3 will have seemed entirely ordinary on the way back from St Joseph's Catholic Primary School, Malmesbury, and they all do — which is the trap with petrol in a diesel instead of the reverse. Diesel in a petrol vehicle generally refuses to run, stopping the motorist and stopping the damage with them. Petrol in a diesel fires up, idles, drives off as though nothing had happened, and all the while the pump works without the lubrication its fuel is supposed to supply. Tell us approximately how far, and how hard. The harder counts more.
Chance the drive home from Rose and Crown? No. It will fire up and it will move off just fine, which is the trouble — a diesel on a thinned tank runs normally while wearing down the components the fuel should be lubricating. Park the BMW 1 Series and call us.
Injection pressure is the part being lost. Petrol thins diesel, and runnier fuel leaks past the close-fitting components that are supposed to build that pressure, and so the farther a diesel Kia Sportage drove, the less well it held. Normal on the way out and sluggish on the way back is how that run to King Althelstan's Mead went, then, and that tank is where to look. Pull in somewhere safe, switch off and phone us.
Why so direct about leaving the keys alone? Because the pump is before your injectors, and a worn one sends whatever it sheds onward with your fuel. Ring us. Leave the Volkswagen Touran near Malmesbury Bowls Club house.
No warning light exists for this, which is why motors in that position usually get driven again before somebody phones. Don't be one of them. The throttle went limp and your idle turned uneven after a few streets, and the diesel Vauxhall Insignia is now resting close to Malmesbury Library. Softness there means fuel that can't build pressure correctly instead of an engine packing up. Turn off. Ring us.
Kerbside call-outs in Burton Hill
Some drivers find no safe spot to pull in whatsoever. Hazards on in a lay-by somewhere, or pulled onto the verge on Priory Lane since you worked it out after setting off — we take that call regularly enough that it is the normal kind.
Out of your car when it isn't wise to be there, with it if it is. Never restart your motor to limp it somewhere handier — a diesel running on petrol will often oblige, and every mile it obliges for is drawing the mix further into the fuel system. Carrying on causes your car far more harm than a technician driving out to an inconvenient place, and that is no bother for us.
Petrol in a diesel, but the car has moved
under 5 miles from Burton Hill, your M4 is what counts here. Some distance along, and onto it in the first place: a wrongly fuelled diesel will frequently do both before anything seems wrong. What you get then is seldom a tidy stop. Power ebbs away, the idle gets uneven, and there may be smoke.
Get off at the first safe exit, switch off, and never restart the vehicle to reposition. On a longer run — anything approaching the under 25 miles to the nearest city — assume the contamination has been through the fuel filter, your pump and the injectors, and say so when you phone. It changes what our technicians bring.

What follows when our engineers reach you in Burton Hill
- Our engineers ask first, price after. What went in? How much? Has your engine run? Those replies alter what the work actually is.
- The tank gets drained of everything.
- Lines rinsed, filter cleared. Whatever is left afterwards is not the thing that started the problem.
- We put clean diesel in and prime your system.
- Our technicians turn it on and make sure it runs smoothly on clean diesel.
From there, you are ready to set off. There's no need to go to a garage at any point, as the work is all done where the vehicle is, and when it's noticed early, long-term damage is very rare.
AdBlue in the diesel tank instead, around Burton Hill?
AdBlue rather than petrol? Then the first step is unchanged — your motor remains off — while this problem under it is a separate one altogether. Petrol does two things to diesel: dilutes it, and removes the lubrication the fuel system depends on. Rust and build-up are what a diesel tank gets instead, because AdBlue is urea in water.
We deal with both, and AdBlue removal around Burton Hill has its own page with the details — including why it's often the more significant of the two.
How much is a petrol-in-diesel drain in Burton Hill?
We can't put one figure on this page frankly, since this job is not one job. What changes it:
- This is the big one: whether the engine has been started, or driven.
- Wrong fuel in, against what that tank takes — that proportion.
- Which got in: petrol or AdBlue.
- Access: the car's position, and whether working on it there is sensible for a van.
The vehicle, the quantity, whether it has run — give us those and the answer comes back straight and not as a range. Not urgent, with your car at home and going nowhere? Then is fine.
Petrol in diesel queries from Burton Hill motorists
Can you do a fuel drain at a petrol station in Burton Hill?
A good portion of this work happens there, so yes. Tell us which one you're at when you call and we will tell you whether our technicians can work there. With the station's consent our technicians attend another forecourt nearby and the other forecourts around town all the time.
Is there a safe amount of petrol in a diesel?
Proportion decides it instead of litres — and more than either, whether the motor has run. What settles how much work is required is if that mix has been sucked through your fuel system — because though five litres in a nearly empty tank is a distinct matter from five in a full one, either way that's the query.
I put petrol in my diesel and drove it. What next?
Switch off somewhere sensible, then keep it that way after you stop. It's salvageable much more often than people fear, even though driving is what takes the issue from your tank into your pump and injectors — and the single most useful thing you can do now isn't restart it.
Fuel drains and manufacturer warranties
A manufacturer's warranty outlasts a drain and flush done to a correct standard, which is no modification at all. A dispute over a warranty is likelier to come from running a diesel on petrol — so leave it switched off.
Two-stroke oil in your tank, and then home?
No. Two-stroke oil is an old remedy for a distinct fault and it doesn't replace what petrol has diluted. The pump still has to cope with it, because that tank still has petrol in it afterwards.
Main dealers and petrol in a diesel
Wherever the vehicle is, we drain and flush it there, so a visit to the main dealer doesn't come into it.
Is the vehicle still with you?
That engine stays off.
Turn it off somewhere safe then keep it off, if you have already driven it. Cold, parked, going nowhere: that is the best place to be in. Drivers fear this a lot more than they need to.
