Put Petrol in a Diesel Car in Low Spennymoor? Don't Start It
If you have not fired up your engine as yet, don't. A fuel drain and nothing else is almost always what a motor needs while the petrol is still sitting in that tank and your engine has not run, which is why it's the coming few minutes that matter, not how much got in. Petrol in Diesel comes to the car wherever it has ended up in Low Spennymoor or the rest of Durham, on the forecourt, by the roadside or on a driveway, and drains and cleans it there. Our engineers shall explain what the next part will be. Phone — it goes before everything else.
The next five steps: petrol in a diesel
- Feed a petrol motor diesel and it will generally refuse to run at all, so the person stops there and so does the wear. Feed a diesel petrol and the car starts, it ticks over, it drives off — fine for several miles. Most people have that backwards, which is the part they get wrong about petrol in a diesel in particular. So do not crank it. And having started, don't depend on it: your fuel system is grinding as you drive.
- Switching the car's ignition on frequently primes the system, and priming is what carries petrol out of your tank and into the pump and injectors. Those are the components diesel keeps lubricated on its way through, before it ignites. Petrol handles the burning and none of the protecting. Leave the car's ignition off.
- Never weaken it. Diesel tipped on top gets rid of nothing, so all you have is more of what was already there, since percentage isn't how a diesel fuel system accepts petrol. Super unleaded? Still petrol. The octane makes no difference.
- Remain where you are if you reasonably can. A vehicle that has not moved is the quickest one to sort, and we'd sooner get to an awkward place than have it started. If you are pulled up on the verge on Coulson Street, put the hazards on then leave the vehicle there.
- Before you dial, get your position. Anything nearest to you with a label on it, plus a postcode that starts DL16 7 — that's what settles whether our van turns up or circles.
- Dial 0333 366 0103. Let us know what went in, about how many litres, and whether the motor has fired. These three details shape the full visit.
How far you travelled is what we query, not how long the vehicle has been stood — and this is why. Diesel performs two roles on its way through an engine: it combusts, and before burning it greases its high-pressure pump and those injectors. Petrol handles the first only. So a rushed top-up on the drive in, the realisation coming around eleven, and a diesel Volkswagen Passat sitting outside Bishop Auckland since quarter past eight tells us those couple of miles were done with the pump labouring on a liquid robbed of a great deal of its protection. Phone and leave the vehicle precisely where it is.
Hazards on. Engine off. Phone us. It is twenty to nine at the gates of North Park Primary School, you're late, and your receipt shows unleaded — and although three miles in your BMW 3 Series feels like nothing, fuel is supplied on demand, and a hurried drive needs plenty of it.
The parts that should be getting lubricated are grinding instead, and the motor gives no sign of it: a diesel on a thinned tank starts and drives off just fine. Try the drive home from The Frog & Ferret? Don't. Ring us then leave the Nissan Qashqai where it stands.
Normal on the way out, flat on the way back. If that's how that run to Bessemer Community Park went, that tank is the place to look. Petrol weakens diesel, and weaker fuel leaks past the tightly fitted components that are meant to build injection pressure — so the further your Audi A4 went, the less well it held that pressure. Stop somewhere sensible, switch off then ring us.
Repaired and starting are not the same thing, and the difference is the circuit: our engineers flush it, and take the filter off where there's a workable one. Compare that with the certain advice you will get — drain the car, refill with new diesel. Half right. Do exactly that to a diesel Volvo XC60 near Spennymoor Day Centre and it will start, which is exactly why the advice sounds sensible. Then the motor sucks the petrol left behind in the filter, and in the feed lines, straight back through your pump, because emptying a tank does nothing whatever about fuel that has already left it. Phone us instead.
On a forecourt: clearing petrol from your diesel
Forecourts are where the job mostly begins, and where a good part of that closes. We operate on station forecourts routinely, with the site's agreement, and so if you are still at Asda that's generally where this drain happens.
At the forecourt, the mistake gets caught with your motor never started, and no place else manages that. Fuel pulled out of that tank and through the filter, right to your high-pressure pump, is what occurs when the engine is fired up and the car is moved to where it is now: the car park, the driveway or the lay-by, anywhere other than the forecourt. So the flush includes the fuel filter and your lines along with the tank. That's still not a catastrophe, and we put it right where the car stands. What determines it is whether the ignition was turned in the seconds after the receipt was checked.
Out from the petrol pump, the next driver can get by — so yes, let the attendants help you wheel it. Very much worth doing. Shifting it four bays does not justify cranking the engine.
Low Spennymoor plus the towns beside it
Those same journeys carry us to Mount Pleasant, Merrington Lane, Tudhoe Grange, Spennymoor and Tudhoe besides Low Spennymoor, which is a residential suburb.
If yours isn't on this list it doesn't mean we never come — there are separate pages for most locations around Durham, and the ones listed above are just the nearest neighbours. Guessing is the thing to skip, especially on the boundary or anywhere your satnav goes wrong. Ring us to enquire.
The ground this page covers is on the map. Roadside, forecourt, drive, car park: every bit of it is territory we serve, and none of it requires the car to come to us.
Roadside stops in Low Spennymoor
The chance to stop somewhere safe does not come to everybody. Set off, then twigged? Ended up on the verge on Vyners Close, or sat in some lay-by with the hazard lights on? That is a common call here. Not a rare one.
Safe where you are? Stay with it. Not safe? Climb out and away from it. It will frequently oblige. A diesel running on petrol limps along perfectly willingly, and that is the trouble: start it up to get to somewhere better and the mixture goes further into the fuel system with every mile covered. A van driving to a tricky location is no problem for us, and it's far better for the vehicle than driving on.
A couple of miles on petrol in a diesel: what next?
under 3 miles out of Low Spennymoor, the A1(M) is what counts now. A drop in power, an uneven idle, smoke: those are the symptoms when they arrive, instead of a tidy stop — and a misfilled diesel will frequently get you onto it and some way along before anything feels wrong at all.
Get off at the next safe exit, switch off, and don't start the vehicle to reposition. Presume the worst of that on a long trip. Anything approaching the under 10 miles to the closest city, and the mixture has been through your filter, through your pump, through the fuel injectors. Say so when you call. What our technicians bring differs.

What our engineers do when we get to you around Low Spennymoor
- Our engineers ask first, quote after. What got in? How much? Has the motor run? Those replies alter what the work really is.
- The polluted fuel is pulled out of your tank.
- What is remaining in the system should not be what started the trouble, so your fuel lines get purged and your filter cleared.
- Bleeding your system follows, once clean diesel is in.
- Once it's turned on, our technicians make sure it runs smoothly on fresh diesel.
After that it's ready to set off. Lasting damage is very uncommon when it has been caught early, and as all of it is done where the vehicle is, it never has to go to a garage.
Low Spennymoor AdBlue removal is a different matter
AdBlue instead of petrol? Then the opening step is unchanged — your engine remains off — whereas the problem underneath it is a distinct one altogether. Petrol thins your diesel and removes the lubrication the system depends on. AdBlue? Urea dissolved in water. Put that in with your diesel and you get rust instead, plus deposits.
Both are ours. There's a separate Low Spennymoor page for AdBlue removal, with the detail on it — including the reasons it usually turns out to be the worse of the two.
Low Spennymoor pricing for a petrol-in-diesel drain
What shifts the figure is laid out below, since this job is not one job and our engineers can't frankly put a single figure on this page.
- Started? Driven? Either answer counts more than anything else on this list.
- The tank's capacity, set against how much of the wrong fuel went into it.
- The type of fluid in the tank, unleaded or AdBlue.
- Whether a technician can sensibly get to your vehicle and work on it, which rests on where the vehicle is.
A straight answer instead of a range is what you get for telling us three things: your car, the amount, and if it has run. Vehicle at home, going nowhere, nothing urgent about it — is ideal for that.
Questions we get about petrol in diesel in Low Spennymoor
Can you do a fuel drain at a petrol station around Low Spennymoor?
Much of what our engineers do gets done nowhere else. So yes. Our engineers work at BP and the other forecourts nearby routinely, with the station's permission — tell us which one you are at when you ring and we will tell you whether our technicians can work there.
A few litres of petrol in a diesel — too much?
Ratio decides it instead of litres — and more than either, whether the motor has run. Five litres in an almost empty tank is a separate situation from five in a full one — but either way, the thing that determines how much work is needed is if that blend has been drawn through your fuel system.
I drove the vehicle after putting petrol in my diesel. What next?
Stop safely. Off. Nothing after that. Not restarting it is the single most helpful thing available to you now. Driving does shift the problem out of that tank and into your pump and injectors, yes, and it remains fixable far more commonly than people fear.
My warranty — does a fuel drain void it?
No. Carried out correctly, emptying and cleaning is no alteration at all, and the warranty from your manufacturer is untouched by it. Another good reason to leave it turned off: running a diesel on petrol is the thing more likely to cause a disagreement with one.
Can I just add two-stroke oil and drive home?
No. It belongs to a separate fault from a separate era, and petrol has thinned something no oil of that kind replaces. Your tank still has petrol in it later on, and the pump still has to cope with it.
A main dealer for petrol in a diesel — needed?
No. We drain and clean the vehicle wherever it is, so there's no need to take it to a main dealer.
Is your car still with you?
Shut off is the way it remains.
Already driven it? Then stop somewhere safe, turn off, then let the car stay that way. A stationary, cold motor is the best position to be in, and this is recoverable from far more regularly than drivers assume.
