Newton Hill: Put Petrol in a Diesel Car?
With that tank still carrying the fuel and the motor not yet turned over, nearly every job takes only a drain, so keep the engine off. That result is decided in the minutes right after the fill-up, and not by the amount that went in. Across Newton Hill and the rest of West Yorkshire, Petrol in Diesel drains your car and flushes it where it sits, whether by a roadside, on a private drive or at a forecourt. Ring us before anything else starts, so you'll hear what comes from there.
What to try now about petrol in a diesel
- Feed a petrol engine diesel and it will typically not run at all, so the person stops there and so does the wear. Give a diesel petrol and the thing starts, it idles, it moves off — fine for several miles. Motorists have that reversed, which is the part they get wrong about petrol in a diesel specifically. So never start the vehicle. And having started, do not believe it: the fuel system is wearing while you drive.
- Leave the car's ignition alone also. Diesel performs two jobs: it combusts, and before it ignites it lubricates the injection pump and those injectors. Petrol does the first and not the second. Switching the car's ignition on is usually sufficient to prime the system, which moves the petrol out of your tank then into exactly those components.
- Do not put diesel on top to thin it. A diesel fuel system won't handle petrol by percentage the way that advice presumes, and topping up gets rid of nothing — it just gives you a bigger tank of the same mix. The grade makes no difference either: super unleaded is just petrol.
- Wait where you are if you safely can. A vehicle that hasn't shifted is the quickest one to handle, and our team would rather get to an awkward location than have it started. If you are pulled up on the verge on Second Avenue, switch those hazards on then keep it there.
- Before you call, work out your position. Anything closest to you with a name on it, plus a postcode beginning WF1 2 — that is what determines whether the technician arrives or circles.
- What went in, approximately how much, plus if your car has run — the three facts determine your whole call-out. Dial 0333 366 0103 then tell us.
At a forecourt: clearing petrol from your diesel
Pumps are where the job usually kicks off, and where a big part of that finishes. If you are still at the forecourt at Total Energies, that is generally where this drain gets done — we work on station forecourts regularly, with the station's agreement.
A forecourt is the single location this can be caught before the engine has run. Anywhere else — a car park, a private drive, a lay-by — the car was switched on and driven to get there, which means fuel was sucked from your tank, through the filter and into your high-pressure pump. That's not a disaster, and our engineers can still sort it out where it sits. It does mean your lines and your filter need flushing as well as the tank, and that is decided by the few seconds between reading the receipt and going for the key.
Attendants will generally help out pushing it away from the petrol pump, which lets the next driver get past. Accept the assistance. Four car lengths isn't worth a restart.
Parts our vans serve around Newton Hill
Newton Hill is a residential suburb, so our team get out to the town and to anywhere near it on those same rounds: Snow Hill, Pinders Fields, Outwood, St Johns and Wrenthorpe.
Not on this list? That tells you nothing. The places above are only the closest few, and the majority of towns across West Yorkshire have a page of their own somewhere on our site. Guessing is the thing to avoid, especially on a boundary or anywhere the satnav struggles. Call us to enquire.
The ground the page includes sits on our map. We work roadside, at forecourts, on driveways and at car parks over all of that, and your vehicle never needs to move to us.
Shift the car out of the gateway and fix it later — that's what someone will say, and it's wrong. Parked on the zig-zags by Newton Hill Community School, a wrongly fuelled diesel Nissan Qashqai is a nuisance and nothing worse. Started three more times for courtesy, it's no longer a tank fault but a fuel system one, because priming occurs with every start and more petrol goes past the fuel filter on to the pump. Let everyone grumble. Ring us.
Here is the whole mechanism. Diesel needs enough body to seal the tight gaps it goes through, and petrol takes that away. That's it. Which explains the ordinary The Plump call — a diesel Dacia Duster, out there without a murmur and back down on power, uneven at idle, perhaps a bit of smoke. Injection systems work hydraulically as well as chemically, and so the fuel has to hold pressure and not just burn; thinned, it leaks past those clearances and not building, and delivery comes poorer, later, less even than your engine was engineered round. Not a failing engine, though. Fuel that has stopped acting like diesel. Put that right and it stops.
Why so firm about leaving the keys alone? Since your pump is ahead of the injectors, and a worn one sends whatever it sheds on with the fuel. Ring us. Leave the Audi A3 close to Kingdom Hall Of Jehovah's Witnesses.
The narrower petrol nozzle fits a current diesel filler neck with almost no resistance at all, which makes this mechanical instead of slapdash. New spots see most of that for that reason. So: filled up near Mental Health Muesum without thinking, in a diesel BMW 5 Series you have had for two days? Call us where you are. Hire and courtesy cars usually get driven further before anyone realises, and mileage determines how much petrol ends up at the fuel injectors.
Repaired and starting are not the same thing, and the difference is the circuit: our technicians flush it, and take the fuel filter off where there is a workable one. Compare that with the certain tip you'll get — drain the car, refill with fresh diesel. Half right. Do precisely that to a diesel Kia Sportage close to Lofthouse Colliery Memorial and it will start, which is precisely why the tip sounds sensible. Then the motor draws the petrol left behind in the filter, and in the feed lines, straight back through the pump, since emptying a tank does nothing whatever about fuel that has already left it. Call us instead.
Newton Hill: broken down wherever you stopped
The opportunity to pull in anywhere sensible does not fall to everyone. Hazards on at a lay-by somewhere, or stopped on the verge on Third Avenue as you worked it out after setting off — our engineers take that call often enough that it's the normal kind.
Sit beside the car if it is wise to be in it, yet clear of it when it isn't. Don't start it up to get to a better location. It will go — a diesel on petrol generally obliges — and each mile of obliging draws the mix deeper into your fuel system. We'll send the van to an inconvenient place without any trouble, and for your car that's far better than driving on.
So you've driven it? Petrol in a diesel over a few miles
The local M1 is the one that matters now, and it lies under 3 miles from Newton Hill. A misfilled diesel will frequently get you onto it and some way along before anything seems wrong, while the symptoms when they come are generally lost power, an uneven idle and some smoke instead of a tidy stop.
The first sensible junction is the one to take. Switch off there, and leave the restarting alone. On a longer run — anything approaching the under 3 miles to the nearest city — assume the mixture has been through the fuel filter, the pump and your injectors, and tell us when you phone. It changes what our engineers bring.

When our engineers get to you in Newton Hill: what happens
- Our engineers find out what was put in, how much, and if your motor has run. The answers change the work, which is why we ask before quoting.
- The tank gets drained of everything.
- Fuel lines are flushed through and the fuel filter cleared, leaving nothing in the fuel system that created any of this.
- The fuel system gets bled, on fresh diesel.
- We start the car and make sure it runs smoothly on new diesel.
At that point it is ready to drive away. There's no need for a workshop at any point, as the work is all done where the car is, and when it is noticed quickly, long-term damage is very uncommon.
AdBlue in your diesel tank instead, in Newton Hill?
If what went in was AdBlue rather than petrol, the first instruction is the same — don't fire it up — yet this issue isn't. Petrol dilutes your diesel and strips the lubrication your fuel system depends on. AdBlue is urea dissolved in water, and in a diesel tank it causes corrosion and deposits in its place.
We cover both, and AdBlue removal in Newton Hill has its own page with the details — including why it is frequently the more significant of the two.
What a petrol-in-diesel drain costs around Newton Hill
One number wouldn't be fair here, since this is not one job. These are the things that change it:
- Has it been run or driven? Nothing else matters for as much.
- The tank's capacity, set against how much of the wrong fuel went into it.
- Whether it is petrol or AdBlue.
- Where your car is, and if a technician can sensibly reach and work on it.
Tell us what the car is, how much went in, and if the motor has run. A firm answer comes back, not a range. Vehicle at home, going nowhere, nothing time-critical about it — is fine for that.
Newton Hill motorists ask us these about petrol in diesel
Can you do a fuel drain at a petrol station around Newton Hill?
A large part of this work happens there, so yes. Routinely, provided the site consents: EG On the Move, plus every other forecourt nearby. Say on the phone where exactly you have stopped. Whether we can work in that spot is something we answer straight away.
How much petrol in a diesel is too much?
Whether your motor has run counts far more, though the ratio matters too, rather than the litres. What determines how much work is needed is if that blend has been pulled through the system — because even though five litres in an almost empty tank is a distinct situation from five in a full one, either way that is the query.
I drove it after putting petrol in my diesel. What next?
Pull in somewhere safe, turn off, and keep it off. Not restarting it is the single most useful thing available to you now. Driving does shift the issue out of your tank then into the pump and injectors, yes, and it stays recoverable far more frequently than drivers expect.
Will a fuel drain void my warranty?
It is not an alteration, so a drain and flush carried out properly doesn't invalidate a manufacturer's warranty. Another reason to leave it switched off: running a diesel on petrol is the thing likelier to cause a dispute with one.
Two-stroke oil in your tank, and then home?
What petrol has diluted isn't put back by two-stroke oil, which is an old fix for a separate fault. So no. Your pump still has to live with it, since that tank still has petrol in it later.
Main dealers and petrol in a diesel
You do not need one. The car is drained and cleaned wherever it is, with no need to bring it to a dealership.
You, and your vehicle, still together?
Turned off is how the car remains.
Already driven it? Then pull in somewhere safe, turn off, then let the car remain that way. A stationary, cold motor is the best place to be in, and this is recoverable from a lot more often than drivers expect.
