Put Petrol in a Diesel Car in North Tawton? Don't Start It
With the tank still holding the petrol and the motor not yet started, almost every job takes only a drain, so leave your engine off. That outcome is settled in the minutes straight after the fill-up, and not by the amount that was put in. Across North Tawton and the rest of Devon, Petrol in Diesel drains your car and cleans it where it sits, whether at a roadside, on a driveway or at a forecourt. Contact us before anything else begins, and you'll learn what comes from there.
Petrol in a diesel: what to do first
- Whenever you drive, the pump and the fuel injectors suffer. This is why you do not crank it, and why you don't believe it once it has started. The thing about petrol in a diesel in particular — the bit motorists get wrong — is that it drives away fine for the first mile or two. Diesel in a petrol engine typically cannot run at all, which stops the driver and stops the wear with them. This one lets you carry on.
- Two tasks, diesel: it burns, and on the way through it keeps the injection pump and injectors oiled. Petrol only manages the one. Which is why the ignition remains off too — switch it on and you often prime the system, and that is petrol exiting that tank for precisely those parts.
- Don't pour diesel on top to thin it. A diesel fuel system will not accept petrol by percentage in the way that advice presumes, and topping up gets rid of nothing — it simply gives you a bigger tank of the same mixture. The type makes no difference either: super unleaded is simply petrol.
- A car that has never shifted is the simplest one to sort out, so stay where you are if you sensibly can. Stopped on the verge on The Square? Hazards on, and keep the vehicle there. A difficult place suits us better than a started diesel.
- Before you call, get your position. Anything closest to you with a sign on it, plus a postcode beginning EX20 2 — that's what settles whether the van shows up or circles.
- Three replies settle the whole job: the liquid you tipped in, the ballpark amount of it, and whether anything has been going since. Our line is 0333 366 0103.
Your high-pressure pump spent that morning run labouring on a fluid that had lost much of the protection it is made for. Diesel lubricates that pump, and the fuel injectors with it, before any of your fuel burns; petrol does the burning and none of the lubricating. So picture a diesel Volkswagen Golf, filled at quarter past eight, driven in to work, and parked sitting outside Lapford till the penny drops at about eleven. Three hours of sitting have altered nothing about it. The couple of miles before that altered a good deal, which is why the thing we put to you is about miles instead of hours. Phone us. Keep the vehicle right where it sits.
How much fuel the pump has sucked is what we are actually asking — not how long ago any of it was. So the call we like runs like this: diesel Renault Megane, some litres of unleaded, a couple of miles driven, now turned off at Costcutter.
How far, and how hard? The second of those counts more than the first, so have both ready. Your BMW 3 Series will have seemed completely usual on the way back from North Tawton Community Primary School and Nursery — they all do, and that's the trap. Diesel into a petrol car generally will not run at all: the motorist stops, and so does the damage. Petrol into a diesel starts, ticks over, moves off like nothing happened, while your high-pressure pump gets on with its work minus the protection the fuel should be giving it. No warning appears, because behind the wheel nothing appears wrong.
Calling from close to North Tawton Town Hall? Three things help us. The filler — which side of the car it is on. Room for a technician alongside you, without the road being blocked. And if anything has run since the fill-up. The location itself scarcely counts: on-street is where our technicians work most, and we'd much rather have a narrow bay than a vehicle somebody has driven somewhere simpler. Then it's a drain for the Dacia Duster, a filter change where there is one worth changing, lines purged, clean fuel put round the entire circuit. By now the worst of it is in the lines and not your tank.
Fixed and starting aren't the same thing, and the difference is the system: our engineers flush it, and take your filter off where there is a serviceable one. Compare that with the sure of themselves tip you will get — drain the vehicle, refill with new diesel. Half true. Do precisely that to a diesel Kia Sportage by St Peter and it'll start, which is precisely why the suggestion sounds reasonable. Then the motor pulls the petrol left behind in your filter, and in the feed lines, straight back through the pump, as draining a tank does nothing whatever about fuel that has already left it. Ring us instead.
Clearing petrol from a diesel at the forecourt
Much of this job starts at a forecourt, so a large portion of that ends up completed on site. Still at the nearest petrol station? Then that's generally where it gets done. Garage forecourts are routine for us, with the agreement of the owner.
Nowhere else but a forecourt can this be caught with your engine still unstarted. The few seconds between reading the till receipt and reaching for the keys settle how much requires rinsing. Anywhere other than the forecourt — a car park, a drive, a lay-by — the car was started and moved to get there, so fuel was pulled from the tank, through the filter and into your high-pressure pump. That means your lines and the filter need rinsing as well as the tank. It's not a calamity, and our technicians can still deal with it where the vehicle stands.
Attendants will generally pitch in pushing it away from the pump, which lets the next motorist get past. Accept the help. Starting the car to shift four car lengths isn't.
Areas our vans serve near North Tawton
Week, Ashridge Court, Trecott, Bondleigh, Itton — each of these on the rounds that carry us over to North Tawton itself, a riverside town.
If yours isn't on this list that does not mean we don't come — there are pages for most towns across Devon, and the ones listed above are simply the closest neighbours. Contact us and enquire rather than guessing — borders above all, and anywhere your satnav can struggle with.
The area this page covers sits on this map. Kerbside, forecourt, driveway, car park: all of it is ground our technicians work on, and none of it needs your vehicle to come to us.
Broken down by the roadside near North Tawton
Some people have no suitable place to pull in whatsoever. If you worked it out after setting off and finished up by the verge on North Street, or at a lay-by somewhere with the hazard lights on, that's a routine call for us and not an unusual one.
Out of your car if it is not safe to sit inside, by it when it is. Never restart your engine to nurse the vehicle somewhere handier — a diesel running on petrol will usually oblige, and every mile it obliges for is pulling the blend further into the fuel system. Driving on causes your car far more harm than a technician coming out to a tricky spot, and that is no trouble for us.
Already driven it? Petrol in a diesel over some miles
This is where the M5 comes in, under 25 miles out of North Tawton. A drop in power, a lumpy idle, some smoke: those are the symptoms when they appear, rather than a neat stop — and a misfilled diesel will often take you onto it and some distance along before anything seems wrong at all.
Pull off at the next safe junction, turn off, and don't restart it to move it. Long run? Anything approaching the under 25 miles to the closest city and you should presume the lot — filter, pump, injectors, all of that reached by the mixture. Say that on the phone, because it affects what goes in the van.

The call-out in North Tawton, step by step
- Three things get checked before any quote — the fuel that was put in, the quantity, and if anything has been run since. Each answer shapes the work.
- The polluted fuel is drawn from your tank.
- Lines purged, filter cleaned. Whatever is left later is not the thing that started the issue.
- The system gets bled, on fresh diesel.
- After it's fired up, we make sure it runs properly on fresh diesel.
Your car is then ready for you to pull away. There's no need to go to a garage at any point, as the work is all done where your car is, and when it is caught soon, permanent damage is very rare.
AdBlue in your diesel tank instead, in North Tawton?
AdBlue rather than petrol? Then the first instruction is unchanged — the engine remains off — while the fault under it's a distinct one altogether. Petrol does two things to diesel: thins it, and removes the protection the system relies on. AdBlue is urea in water, and in a diesel tank it causes corrosion and build-up instead.
Our technicians cover both, and AdBlue removal in North Tawton has its own page with the full story — including why it's usually the more significant of the two.
Paying for a petrol-in-diesel fuel drain in North Tawton
What moves the price is listed below, because this job isn't one job and our technicians can't frankly put a single number 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 got into it.
- The sort of fluid in the tank, petrol or AdBlue.
- Access: the car's position, and if working on it there's sensible for a van.
Tell us what your vehicle is, how much got in, and if the motor has run. A clear answer comes back, not a range. Car at home, going nowhere, nothing pressing about it — is fine for that.
Petrol in diesel: common queries around North Tawton
At a petrol station around North Tawton, can you do a fuel drain there?
Plenty of what our engineers do takes place nowhere else. So yes. Regularly, provided the site agrees: BP, plus every other forecourt nearby. Say on the phone where exactly you have stopped. Whether we can work in that place is something we answer straight away.
A couple of litres of petrol in a diesel — too much?
Whether your motor has run counts much more, though the proportion matters too, instead of the litres. Five litres in an almost empty tank is a separate case from five in a full one — but either way, the thing that determines how much work is required is if that blend has been pulled through your fuel system.
I drove the vehicle after putting petrol in my diesel. Now what?
Stop somewhere sensible, turn off, then leave it off. Driving is what moves the issue from the tank into the pump and injectors — but it is recoverable far more often than people fear, and the single most helpful thing you can do now is not restart the vehicle.
Will a fuel drain void my warranty?
A manufacturer's warranty survives a drain then flush done to a good standard, which is no alteration at all. Another good reason to leave it switched off: running a diesel on petrol is the thing more likely to cause a disagreement with one.
Could I put some two-stroke in and just drive?
No. It belongs to a separate fault from a bygone era, and petrol has diluted something no oil of that kind replaces. Your tank still has petrol in it after that, and your pump still has to cope with it.
Main dealers and petrol in a diesel
You do not need one. The vehicle is drained and flushed wherever it is, with no need to bring it to a dealership.
Is your car still with you?
Leave the engine shut off.
Already driven it? Then stop somewhere sensible, turn off, then let it remain that way. A stationary, cold motor is the best position to be in, and this is recoverable from a lot more commonly than people assume.
