Put Petrol in a Diesel Car in Drumlough? Don't Start It
With the tank still carrying the fuel and the motor not yet run, nearly every job takes only a drain, so leave the motor off. That outcome is determined in the minutes immediately after the fill-up, rather than by the amount that was put in. Throughout Drumlough and the rest of County Down, Petrol in Diesel drains your car and flushes it where it is, whether at a roadside, on a drive or at a forecourt. Just one ring to us is sufficient: our technicians will tell you what happens from here. Make it right away.
Petrol in a diesel: what to do now
- Whenever you drive, the pump and the fuel injectors wear down. This is why you don't start it, and why you never rely on it once it has started. The thing about petrol in a diesel especially — the part people get wrong — is that it drives off happily for the first mile or two. Diesel in a petrol motor normally will not run at all, which stops the driver and stops the damage with them. This one lets you keep going.
- Diesel burns, and before it burns it protects — your high-pressure pump, the injectors. Petrol does only the burning. So leave your ignition off too: flicking it on is frequently enough to prime your system, and priming carries petrol from that tank into precisely those parts.
- Don't put diesel on top to thin it. A diesel fuel system will not handle petrol by percentage as that guidance suggests, and topping up clears nothing — it just gives you a fuller tank of the same blend. The type makes no difference either: super unleaded is just petrol.
- We would much rather come to an awkward place than have it started — so if you safely can, stay put. Nothing is quicker to handle than a motor that hasn't moved. On the verge on B7041, that means hazards on and leave the car.
- Check where you are before calling. A postcode starting BT34 5, and the name of whatever is nearest to you. Otherwise the technician circles instead of arriving.
- Three replies shape your whole visit: the stuff you put in, the rough quantity involved, and if anything has been running since. Our number is 0333 366 0103.
Petrol in a diesel Renault Clio, parked at the nearest station since first thing? The day has cost you nothing — fuel sitting in a tank is idle. It was the trip in that drew thinned diesel through your pump. Phone us before you move it.
If you have put petrol in your diesel Skoda Octavia in Drumlough and you're now sat at the local shops with a boot loaded with shopping, phone. Never fire it up again to exit the spot. We'll come to you, empty your tank, clean your fuel lines then put new diesel in so you can get home. A mile or so at light throttle draws little fuel, so those are usually the easy cases.
A passer-by will tell you to move the car out of that gateway and sort it out later. Please don't. A wrongly fuelled diesel Nissan Qashqai on the zig-zags at the local primary school is an inconvenience; the same car fired up three more times to be helpful is a fuel system instead of a tank. Every restart primes the lines and pulls more petrol past the filter then into the pump. Leave it there, let them grumble, and call us.
Rattling? Uneven idle? White smoke, throttle gone soft? That's your wrongly fuelled BMW 1 Series, a diesel, saying what is wrong with it. Stop wherever you happen to be, possibly close to a street just off the centre, and leave the restarting alone.
A few streets, then it stopped. Throttle limp, idle uneven, and the diesel Citroen C3 is parked up by the far end of the built-up part. Your engine is not packing up — that deadness is fuel that will not build pressure. There's no light on the dash for it, and so cars like yours usually get driven again before anybody picks up the phone. Do not. Off, and ring us.
Can petrol be taken from your diesel on a forecourt?
Most of the work starts at the pump, which means a large chunk of that is completed on site. The drain generally happens on the spot. Still on the forecourt at the nearest petrol station? Given the station's agreement, that is a place our engineers work, and often.
Before your engine has fired — a garage is the single location the mistake ends up spotted. Our engineers can still put it right where it stands, even away from the pumps. In a car park, on a driveway or in a lay-by, the car has been fired up and moved there, and that pulled fuel through the fuel filter then into the high-pressure pump, right from the tank. None of that is a calamity, though the flush then has to go past that tank to the lines and the filter, and the few seconds between reading your receipt and going for your key are what decide that.
Staff will generally help out pushing it out from the pump, which lets the next motorist get by. Welcome the assistance. Rolling it four bays does not merit starting the engine.
Can we serve your end of Drumlough?
These same trips get us to Rathfriland, Hilltown, Corbet, Mayobridge and Monteith besides Drumlough, which is a small village.
If yours isn't on this list that does not mean we do not come — there are separate pages for most towns around County Down, and the ones mentioned above are simply the immediate neighbours. Guessing is the thing to skip, especially on the boundary or anywhere your phone goes wrong. Call us and ask.
That map shows the patch this page covers. We operate at the roadside, at forecourts, on driveways and in car parks throughout all of that, and the car does not need to come to us.
Stuck at the roadside near Drumlough
A chance to stop somewhere safe doesn't fall to everyone. Set off, then noticed? Ended up along the verge beside B7065, or stuck in some lay-by with your hazards flashing? That is a normal call here. Not an odd one.
Out of the vehicle while it's not safe to sit in it, beside it when it is. Do not restart it to reach a nicer spot. It'll go — a diesel on petrol usually obliges — and each mile of obliging pulls the mixture deeper into the fuel system. Driving on does your car far more harm than a van heading out to a difficult place, and that's no problem for us.
Petrol in a diesel, but your car has gone
Here is where your M77 comes into it — over 50 miles away from Drumlough. It will often take you onto it, and some way along, before you spot a thing. Then it's smoke, a rough idle and power draining away — not a tidy stop. Wrongly fuelled diesels rarely give you one of those.
The next safe junction is the one to take. Turn off there, then leave the restarting alone. It affects what we bring, and so say so when you phone: on a longer run — anything close to the under 10 miles to the closest city — assume the contamination has been through the fuel filter, your pump and the fuel injectors.
Drumlough itself
Drumlough is a small locality in County Down, situated inland at an elevation of 108 metres, approximately 7.5 miles from Newry. Drumlough is characterised by its predominantly detached housing stock, reflecting the area's residential nature. Drumlough sits within a wider landscape of rolling hills and countryside, near to the towns of Rathfriland and Hilltown.
What happens when our technicians arrive with you in Drumlough
- We find out what went in, how much, and if your motor has run. The answers alter the work, which is why our engineers ask before giving a price.
- Our technicians empty the tank of the polluted mixture.
- Our engineers flush the lines and clean your filter, so what is remaining in the system isn't what created the issue.
- Fresh diesel goes in, and then the fuel system gets bled.
- The engine is turned on and checked to confirm it runs smoothly on clean diesel.
The vehicle is then ready for you to pull away. Permanent damage is very uncommon when it has been caught soon, and because everything is done where the car is, it never has to go to a workshop.
AdBlue in a diesel tank around Drumlough is a distinct problem
Do not crank it: that first rule holds whether what went in was AdBlue or petrol. What changes is this issue itself. Petrol does two things to diesel: weakens it, and takes away the protection the fuel system depends on. AdBlue is urea in water, and in a diesel tank it brings rust and residue in its place.
AdBlue removal in Drumlough has a page of its own with the details on it, including why it's usually the more serious of the two. Our engineers cover both.
Drumlough prices for a petrol-in-diesel fuel drain
What changes the price is laid out below, since this job isn't one job and our engineers cannot honestly put a single figure on this page.
- Whether the engine has been run or driven. This is the main one.
- Wrong fuel in, against what that tank takes — that ratio.
- Which got in: unleaded or AdBlue.
- Access: the vehicle's position, and if working on it there's sensible for a technician.
Tell us what your car is, how much went in, and whether your motor has run. A straight answer comes back, not a range. For the car at home that is going nowhere and isn't urgent, works too.
Drumlough motorists ask us these about petrol in diesel
I am on a forecourt around Drumlough. Can you drain the car on the spot?
Much of what our technicians do happens nowhere else. So yes. Routinely, provided the site agrees: another forecourt nearby, 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 there and then.
How much petrol in a diesel is too much?
It depends on the ratio rather than the litres, and a lot more on whether the engine has run. Five litres into a nearly dry tank is not five into a full one, no. But both land on the same query in the end: has that mix been pulled right through, or has it not?
I put petrol in my diesel and drove the vehicle. 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 salvageable much more commonly than people 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, clearing and flushing is no modification at all, and the warranty from your manufacturer is untouched by it. What's likelier to start an argument is a diesel that has been run on petrol. One more reason for your engine to remain off.
Adding two-stroke oil, then driving home
Two-stroke oil solves a separate issue, and an old one at that. Nothing it does puts back what petrol weakened. No. After that? Still petrol in the tank, and a pump that has to live with the stuff.
Main dealers and petrol in a diesel
Not at all. We drain and clean the vehicle wherever it is, so there's no need to bring it to a dealership.
Waiting next to it?
Keep the car shut off.
Already driven it? Then pull over somewhere safe, switch off, and let the vehicle stay that way. This is recoverable from a lot more commonly than people expect, and a parked, cold car is the best position to be in.
