Petrol in a Diesel Car in Jack-in-the-Green
With that tank still holding the fuel and your engine not yet started, almost every job needs only a drain, so leave the engine off. That outcome is settled in the minutes immediately after the fill-up, and not by the amount that got in. Across Jack-in-the-Green and the rest of Devon, Petrol in Diesel drains your car and flushes it where it is, whether at a roadside, on a drive or at a forecourt. Our team will explain what your next step will be. Phone — that happens ahead of all else.
The first five minutes: petrol in a diesel
- Don't start the vehicle — and never rely on it when it runs. This is the part most people have wrong about petrol in a diesel in particular. A petrol motor given diesel usually just cannot run, and so the motorist stops and the harm halts with them. A diesel filled with petrol typically starts, ticks over and moves off quite happily for a couple of miles. It is not all right. It's wearing that fuel system while you drive.
- Switching your ignition on frequently primes that system, and priming is what pulls petrol out of the tank and into your 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 oiling. Leave the car's ignition off.
- That guidance assumes a diesel fuel system copes with petrol by percentage. It doesn't. Pour diesel on top and nothing at all is removed; what you have is a bigger tank of the same mixture. And no, the grade makes no difference — super unleaded is just petrol.
- We would sooner travel to a tricky place than have it started — so if you reasonably can, stay still. Nothing is simpler to sort than a car that hasn't moved. On the verge on Cedar Court, that means hazards on then keep it.
- A van turning up instead of circling rests on two things: a postcode beginning EX5 7, and whatever is closest to you with a label on it. Get both ready before you phone.
- What got in, approximately how much, plus whether the car has run — the three details settle your whole call-out. Phone 0333 366 0103 and tell us.
On a forecourt: draining petrol from your diesel
Most of the job starts at the pump, meaning a large portion of it ends up finished on site. We operate on station forecourts regularly, with the station's consent, and so if you're still at Murco that is generally where this drain gets done.
At the forecourt, the mistake is caught with the engine never started, and no place else manages that. The few seconds between seeing the till receipt and reaching for your key determine how much needs rinsing. Anywhere other than the forecourt — a car park, a driveway, a lay-by — the car was started and moved to get there, so fuel was drawn from the tank, through your filter then into the high-pressure fuel pump. That means the fuel lines and your filter require flushing as well as the tank. It is not a calamity, and we can still sort it out where the car stands.
Out from the pump, the next motorist can get past — so yes, let the attendants help you wheel the car. Very much worth it. Starting the car just for four car lengths? No.
Petrol in the Volkswagen Tiguan, and it takes diesel? Shopping in the boot, you outside Morrisons, somewhere around Jack-in-the-Green? Then call us, and leave the engine out of it — not even to exit the bay. Someone gets to you. Tank emptied, fuel lines purged, clean diesel in, and home you go. Easy throttle over a mile pulls very little, and so these are usually the easy jobs.
It will start. It will drive off just fine. That is the trouble, as a diesel on a diluted tank acts generally while wearing the parts its fuel should be lubricating. So no, do not risk the journey home from The Cranberry Farm — leave the Audi A4 and call us.
Here's the entire process. Diesel needs enough body to seal the tight tolerances it goes through, and petrol takes that away. That is it. Which explains the ordinary Cranbrook Ecology Park call — a diesel Ford Focus, out there without complaint and back down on power, uneven at idle, maybe a bit of smoke. Injection systems work hydraulically as well as chemically, so your fuel has to hold pressure and not just burn; diluted, it bleeds past those gaps 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 behaving like diesel. Put that right and it stops.
About as well as this goes, once the motor has turned: away from the pumps, receipt read, and the diesel Dacia Duster parked near Rockbeare War Memorial scarcely two streets on. Call us, and leave the vehicle off. A short hop does genuinely help. It was still a start and still a drive, though, so the fuel filter and the pump have had diluted fuel through them — hence purging the lines instead of only clearing your tank.
Drain it and put fresh diesel in — that is the suggestion you'll get, normally from somebody confident, and it's half right. Do exactly that to a diesel BMW 5 Series close to Rockbeare Village Hall and it would start, which is what makes the suggestion sound reasonable. What takes place next is the issue: your engine straight away sucks the petrol still resting in the fuel filter and the feed lines straight back through your pump, as draining a tank does nothing about fuel that has already left it. Ring us instead. We flush your system and take the fuel filter off where the car has a working one, which is the difference between the car being repaired and the car merely starting.
Do our engineers reach your side of Jack-in-the-Green?
These same rounds take us to Rockbeare, Cranbrook, Higher Burrowtown, Strete Ralegh and Hand and Pen as well as Jack-in-the-Green, which is a residential suburb.
We still come. The places above are only the nearest neighbours, and a page exists for the majority of places in Devon, and so an absence from the list is not an absence from our coverage. Contact us to check instead of presuming — county lines particularly, and anywhere your phone might get wrong.
The area the page covers is on this map. The vehicle does not need to move to us. Our technicians work across all of that — kerbside, forecourts, driveways, car parks.
Stranded at the roadside anywhere around Jack-in-the-Green?
Not everybody gets a chance to stop anywhere suitable. Hazards going in a lay-by somewhere, or stopped on the verge beside Broomfield View as you realised after setting off — we take that call regularly enough that it's the normal kind.
Wait beside the vehicle if it's wise to be there, yet out of the car if it is not. Every mile a diesel obliges you for on petrol draws that mix further into the fuel system — and oblige it frequently will, which is why the engine doesn't get restarted to limp somewhere safer. However tricky the location, it is no problem for us to get to it, and that is far better for the car than driving on.
A couple of miles on petrol in a diesel: what next?
Here is where the local M5 comes in, under 3 miles away from Jack-in-the-Green. Some way along, and onto it in the first place: a wrongly fuelled diesel will often manage both before anything feels wrong. What you get then is rarely a neat stop. Power falls away, the idle gets rough, and there may be some smoke.
The first safe junction is the one to take. Turn off there, then leave the restarting alone. Long run? Anything approaching the under 10 miles to the nearest city and you should assume the lot — filter, pump, injectors, all of that got to by the petrol. Say that on the phone, as it changes what goes in the van.

What follows when we reach you in Jack-in-the-Green
- The responses change the work, which is why our engineers ask before pricing: what went in, how much of that, and whether the motor has run.
- Away flows the contaminated fuel.
- Lines purged, filter cleaned. Whatever remains later isn't the thing that started the trouble.
- Our technicians pour fresh diesel in and bleed the system.
- After it's turned on, our engineers make sure it runs properly on fresh diesel.
Your car is then ready for you to drive away. All of it is done where the car is, so it never has to be taken to a workshop, and when it has been spotted quickly, long-term damage is very unusual.
AdBlue in your diesel tank by mistake, around Jack-in-the-Green?
AdBlue instead of petrol? Then the opening rule is unchanged — your engine remains off — while this issue underneath it is a separate one altogether. Diluted diesel, and no protection left for the system that relies on it. That's petrol. AdBlue is urea dissolved in water, and in a diesel tank it brings corrosion and deposits in its place.
Frequently the more serious of the two, AdBlue — and the full story lives on its own Jack-in-the-Green page. Both are ours to deal with.
What a petrol-in-diesel drain costs around Jack-in-the-Green
Honestly, no single price belongs on a page like this. This job differs. Here's what moves it:
- Whether your motor has been run or driven. This is the big one.
- How much of the wrong fuel got in, against how much that tank takes.
- Which got in: petrol or AdBlue.
- Whether our van can safely reach your vehicle and work on it, which hinges on where your vehicle is.
Tell us your car, the amount and whether it has run, and you'll get a clear answer rather than a range. For the vehicle at home that's going nowhere and is not time-critical, works too.
Petrol in diesel queries from Jack-in-the-Green motorists
Fuel drains on a Jack-in-the-Green petrol station forecourt
Plenty of what we do takes place nowhere else. So yes. Tell us which one you are at when you ring and we'll tell you if our engineers can work there. With the station's agreement we work at Texaco and the other forecourts nearby routinely.
Is there a sensible quantity of petrol in a diesel?
It rests on the ratio instead of the litres, and much more on whether the engine has run. Five litres into an almost dry tank is not five into a full one, no. But both land on the same query in the end: has that mix been drawn right through, or has it not?
I drove it after putting petrol in my diesel. Now what?
Somewhere safe, then stop, then switch off and keep it off. Driving is what takes the trouble from your tank into the pump and injectors — but it's fixable much more often than motorists fear, and the single most helpful thing you can do now is not restart the car.
Is a fuel drain going to void my warranty?
No. Carried out correctly, emptying and cleaning is no alteration at all, and the warranty from your manufacturer is untouched by it. A disagreement 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 fix for a different issue and it does not replace what petrol has diluted. Later? Still petrol in your tank, and a pump that has to put up with the stuff.
Main dealers and petrol in a diesel
Wherever your car is, our technicians drain and clean it there, so a drive to the main dealer does not come into it.
You, and the vehicle, still together?
Never turn your engine back on.
If you have already driven the car, pull over somewhere sensible, switch it off then leave it off. This is recoverable from far more commonly than drivers fear, and a stationary, cold car is the best position to be in.
