Lowes Barn: Put Petrol in a Diesel Car?
If you have not turned on the motor yet, don't. A drain and nothing else is nearly always what a car needs while the fuel is still in your tank and your engine has not been started, which is why it's the next few minutes that count, not how much was put in. Petrol in Diesel comes to the car wherever it has stopped in Lowes Barn or the rest of Durham, on the forecourt, by the roadside or on a driveway, and drains and flushes it there. We will explain what your next step will be. Contact us — this goes ahead of everything else.
Petrol in a diesel: what to do next
- Feed a petrol motor diesel and it will typically fail to run at all, and so the motorist stops there and so does the damage. Feed a diesel petrol and the car starts, it idles, it moves off — all right for a few miles. Most people have that reversed, which is the thing they get wrong about petrol in a diesel specifically. So don't fire it up. And having started, do not depend on it: the fuel system is wearing down as you drive.
- Diesel burns, and before it burns it protects — your high-pressure pump, its injectors. Petrol handles only the burning. So leave the ignition off also: flicking it on is frequently enough to prime the system, and priming carries petrol from the tank into precisely those components.
- Topping up takes out nothing. It leaves you a fuller tank of the same blend, since a diesel fuel system will not tolerate petrol by percentage the way that advice presumes — so don't add diesel on top to dilute it. Type is beside the point too: super unleaded is petrol.
- Stay put if it is wise to. Hazards on, ignition off, leave the car. Wherever you have stopped — the verge on Hastings Avenue, anywhere — an odd location for us trumps a started motor, and nothing is quicker for us to deal with than a car that never moved.
- Before you call, gather your position. Anything next to you with a sign on it, plus a postcode starting DH1 3 — that is what settles whether the van turns up or circles.
- Call 0333 366 0103. Say what went in, about how many litres, and also whether the car has fired. These three facts shape the whole visit.
Can petrol be taken out of a diesel at the forecourt?
A fair share of the job gets done at a pump, because that is where it usually kicks off. The drain usually happens right there. Still on the forecourt at Shell? Given the station's consent, that is a place we work, and routinely.
At a forecourt, this is caught with your motor never fired, and no place else does it. Everywhere else — a car park, a drive, a lay-by — the car was switched on and moved to get there, which means fuel was pulled from the tank, through your filter then into the high-pressure fuel pump. That's not a catastrophe, and our technicians can still put it right where it stands. It does mean your lines and the fuel filter need rinsing as well as that tank, and that is determined by the few seconds between checking the receipt and reaching for the keys.
Push it out of the way if the attendants volunteer, and they generally will. The next motorist gets past the pump, and that's worth doing. Starting the car to shift four vehicle lengths is not.
How much fuel your pump has sucked is what we're really asking — not how long ago any of that was. So the call our engineers hope for sounds like this: diesel BMW 3 Series, some litres of unleaded, a couple of miles covered, now shut off at Tesco.
How far, and how hard? The second of those matters more than the first, so have both ready. Your Peugeot 308 will have seemed entirely usual on the way back from Neville's Cross Primary School and Nursery — they all do, and that is the snag. Diesel into a petrol vehicle usually will not run at all: the person stops, and so does the harm. Petrol into a diesel fires up, ticks over, pulls away like nothing happened, whilst the high-pressure pump gets on with its work minus the lubrication the fuel should be giving it. No warning appears, as behind the wheel nothing appears wrong.
Pulled off the forecourt, read the till receipt, and parked the diesel Ford Focus up near America a few hundred yards later? That's about as well as this goes once your engine has turned. Call us then leave it off. The short distance truly helps, but it was still a start and a drive, and so diluted fuel has arrived at the fuel filter and your pump — which is why our engineers rinse your lines instead of only clearing the tank.
The narrower petrol nozzle goes into a newer diesel filler neck with almost no resistance at all, which makes this mechanical rather than slapdash. Strange spots see most of that for that reason. So: filled up close to China without thinking, in a diesel Dacia Duster you have had for two days? Call us where you are. Hire and courtesy cars usually get driven further before anybody realises, and miles settles how much petrol ends up at the injectors.
Drain it and put fresh diesel in — that is the advice you will get, typically from someone confident, and it is only half right. Do exactly that to a diesel Mercedes E-Class close to Italy and it would start, which is what makes the tip sound plausible. What occurs next is the trouble: your engine immediately draws the petrol left sitting in the filter and the feed lines straight back through the pump, as draining a tank does nothing about fuel that has already left it. Call us instead. Our technicians flush your circuit and take the filter off where the vehicle has a workable one, which is the difference between your car being put right and the vehicle simply starting.
Can our engineers cover your part of Lowes Barn?
Those same journeys carry us to Merryoaks, Elvet Hill, Stonebridge, Nevilles Cross and Crossgate Moor along with Lowes Barn, which is a residential suburb.
Not on this list? That means nothing. The places above are simply the nearest few, and most locations in Durham have a page of their own elsewhere on this site. Ring us and enquire rather than assuming, particularly where you are on a boundary or somewhere a satnav misreads.
The area this page covers appears on this map. Every bit of it is territory our technicians work: a roadside, a forecourt, a drive, a car park. You never bring your vehicle anywhere.
Broken down on the roadside in Lowes Barn
Some people find no sensible place to pull over at all. A common call for us rather than an odd one: noticed after setting off, landed on the verge of Neville Square or at a lay-by with your hazards going.
Whether you stay beside the motor or keep clear of it turns on whether staying in it is sensible. Never fire up the engine to nurse it somewhere better — a diesel running on petrol will often oblige, and every mile it obliges for is pulling the mix further into your fuel system. Carrying on does your car far more harm than a technician driving out to a difficult place, and that is no bother for us.
So you've driven it? Petrol in a diesel after a couple of miles
Here is where the local A1(M) matters, under 3 miles away from Lowes Barn. A drop in power, a lumpy idle, some smoke: those are the signs when they appear, instead of a clean stop — and a misfilled diesel will often take you onto it and some distance along before anything feels wrong at all.
The first sensible exit is the one to take. Switch off there, and leave the restarting alone. On a longer trip — anything near the under a mile to the nearest city — assume the mixture has been through your filter, the pump and the injectors, and mention it when you phone. It changes what our technicians bring.

What our technicians do when we get to you around Lowes Barn
- Our technicians ask first, quote after. What went in? How much? Has the motor run? Those responses shape what the work actually is.
- Away flows the polluted mixture.
- Fuel lines are flushed through and your filter cleared, leaving nothing in the system that caused any of this.
- Priming follows, once fresh diesel is in.
- The engine is turned on and checked to confirm it runs correctly on clean diesel.
After that it's ready to pull away. Long-term damage is very uncommon when it has been noticed early, and because everything is done where your car is, it never needs to be taken to a garage.
A different problem: AdBlue in a diesel tank around Lowes Barn
The fault is not the same, though the opening step is — don't start it — if what got in was AdBlue instead of petrol. The protection a fuel system relies on is stripped away by petrol, which dilutes the diesel. Urea dissolved in water, AdBlue, and in a diesel tank that leads to corrosion and build-up.
Both are ours. There's a separate Lowes Barn page for AdBlue removal, with the details on it — including the reasons it frequently turns out to be the worse of the two.
How much is a petrol-in-diesel fuel drain in Lowes Barn?
What shifts the price is listed below, as the job isn't one job and our engineers can't honestly put a single price on this page.
- Whether the motor has been run or driven. This is the main one.
- How much of the wrong fuel got in, judged against how much the tank takes.
- AdBlue or unleaded, whichever went in.
- Access: the car's position, and whether working on it there's sensible for our van.
The vehicle, the amount, whether it has run — give us those and the answer comes back clear rather than as a range. Not time-critical, with the vehicle at home and going nowhere? Then does the job.
Things we hear about petrol in diesel in Lowes Barn
At a petrol station in Lowes Barn, can you do a fuel drain there?
Much of what our technicians do happens nowhere else. So yes. Agreement from the site is the condition. Given that, a forecourt like Jet is somewhere we're frequently, along with the rest of them locally — so name yours on the phone and you'll hear if working there's possible.
Is there a safe amount of petrol in a diesel?
Whether the engine has run counts far more, though the ratio matters too, rather than the litres. Five litres in an almost empty tank is a distinct situation from five in a full one — but either way, the thing that decides how much work is needed is if that mix has been sucked through the system.
I drove it after putting petrol in my diesel. What now?
Stop sensibly. Off. Nothing after that. Driving is what shifts the issue from that tank into your pump and injectors — but it's fixable a lot more regularly than drivers fear, and the single most helpful thing you can do now isn't restart the car.
My warranty — does a fuel drain void it?
No. Carried out properly, emptying and flushing is no alteration at all, and the warranty from your manufacturer is untouched by it. 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?
What petrol has weakened is not replaced by two-stroke oil, which is an old remedy for a separate problem. So no. Your tank still has petrol in it later on, and your pump still has to put up with it.
Main dealers and petrol in a diesel
Wherever your car is, our engineers drain and clean it there, so a visit to the main dealer does not come into it.
You, and your car, still together?
Shut off is how it stays.
If you have already driven the car, stop somewhere safe, turn it off then leave it off. Cold and stationary, a vehicle is in the best position available — and motorists fear this much more than the recovery rate warrants.
