Portrack: Put Petrol in a Diesel Car?
With the tank still carrying the fuel and the engine not yet turned over, almost every job needs only a drain, so leave the engine off. That result is decided in the minutes immediately after the fill-up, rather than by the amount that got in. All over Portrack and the rest of Durham, Petrol in Diesel drains the car and flushes it where it sits, whether at a roadside, on a driveway or at a forecourt. Call us and then our team shall tell you what comes next before you try any more.
Now what? Petrol in a diesel, step by step
- Don't crank it — and never trust it when it runs. That is the bit drivers have wrong about petrol in a diesel especially. A petrol engine fed diesel normally just will not run, so the motorist stops and the wear stops with them. A diesel filled with petrol generally starts, ticks over and moves off quite happily for a few miles. It is not fine. It's eating into your fuel system whenever you drive.
- Leave your ignition alone too. Diesel has two tasks: it combusts, and before it combusts it greases the high-pressure pump and the injectors. Petrol does the first but not the second. Switching your ignition on is usually sufficient to prime that system, which draws this petrol out of the tank and into precisely those components.
- Never water down it. Diesel added on top gets rid of nothing, and so all you have is more of what was already there, since percentage isn't how a diesel fuel system copes with petrol. Super unleaded? Still petrol. The type makes no difference.
- Sit tight if it is safe to. Hazards on, motor off, keep it. Wherever you have stopped — the verge on Blue House Point Road, anywhere — a difficult place for us beats a started engine, and nothing is quicker for us to handle than a motor that never shifted.
- Have your location prepared before you phone. A postcode that starts TS18 2 and whatever is closest to you with a name on it is the difference between a van arriving and a van circling.
- Three answers shape the full job: the fuel you tipped in, the rough amount involved, plus whether it has been running since. The line is 0333 366 0103.
Can petrol be drained out of a diesel on a forecourt?
Forecourts are where this job often kicks off, and where a large portion of that ends. The drain normally takes place there and then. Still on the forecourt at Asda? Given the station's consent, that's a place we work, and routinely.
At the forecourt, it is caught with your engine never fired, and nowhere else does that. Our technicians can still sort it out where it sits, even away from the forecourt. In a car park, on a private drive or in a lay-by, the car has been started and driven there, and that pulled fuel through the filter then into your high-pressure pump, all the way from your tank. None of that is a catastrophe, although the flush then has to reach past the tank to the lines and your filter, and the few seconds between checking your receipt and going for the keys are what settle that.
Clear of the pump, the next customer can get past — so yes, let the staff help you wheel the car. Worth doing. Shifting it four spaces does not justify firing it.
The awkward part is the bay, not the fuel. Cars either side of you, a trolley shelter behind, and now and then a height limit on the way in that determines if a van can get to you at all — so when you call from a car park like the one at Asda, mention how much space there's round you and which way round your car is. Those our engineers attend often. Should there be no room to work beside the diesel Skoda Octavia, it gets rolled with the motor off, and not out of fussiness over a handful of seconds of running: priming happens at every start, more of the blend leaves the tank for the pump, and two shunts into a roomier bay have gradually made a bigger job of what was just a motor sitting still.
A diesel pump meters fuel to demand, and a hurried morning dash needs plenty — so three miles in your Peugeot 308 sounds like nothing and is not. Twenty to nine outside Tilery Primary School, already late, the receipt in your hand reading unleaded: hazards on, ignition off, call us.
About as well as this goes, once the engine has turned: away from the pumps, receipt read, and the diesel Ford Kuga left close to Mound scarcely two streets on. Call us, then leave it off. A short drive does really help. It was still a start and still a drive, though, so the filter and the pump have had thinned fuel through them — hence flushing the lines rather than only clearing that tank.
Authorisation first, where there is a hire firm or a company behind the car — some agreements demand it, and settling that beforehand saves a great deal of time later. After that, ring us about your diesel Volvo XC60 close to The Range. You'll not know how full the tank was. Scarcely anybody does, two days into a motor, and it gets worked out on the spot regardless. We ask because the harm petrol does in a diesel is proportional: a few litres in an almost empty tank make a much stronger blend than the same few in a full one, and since petrol is designed to resist igniting under pressure, which is precisely what a diesel relies on, the stronger it gets the more the engine rattles and smokes and flattens off.
No warning light exists for this, which is why vehicles in that position usually get driven a second time before somebody rings. Please don't be one of them. The throttle went dead and the idle turned lumpy after a couple of streets, and your diesel Renault Captur is now sitting close to TeamSport Stockton. Sluggishness there means fuel that cannot build pressure properly instead of a motor failing. Turn off. Ring us.
Service near Portrack
St Anns Hill, Newport, Mount Pleasant, Stockton-on-Tees, Queens Park — every one of them on our trips that bring us over to Portrack itself, a residential suburb.
If yours is not on this list it does not mean we don't come — there are separate pages for the majority of locations across Durham, and the ones mentioned above are just the nearest neighbours. Assuming is the mistake to skip, particularly on the boundary or somewhere your satnav fails. Call us and enquire.
This map shows the ground the page includes. We work at the roadside, at forecourts, on driveways and at car parks across all of that, and the vehicle does not need to travel to us.
Stopped on the kerb anywhere in Portrack?
The chance to pull in anywhere safe doesn't come to everyone. Hazards on in a lay-by somewhere, or stopped on the verge of Marston Road since you realised after setting off — we take that call often enough that it's the ordinary kind.
Wait by the car while it's sensible to be in it, but out of the car when it isn't. Every mile a diesel obliges you for on petrol draws that mixture further into the fuel system — and oblige it usually will, which is why your motor doesn't get restarted to limp somewhere better. However tricky the location, it is no trouble for us to get to it, and that's much better for the car than carrying on.
Petrol in a diesel, but your car has rolled
This is where the A1(M) comes in — under 15 miles away from Portrack. A drop in power, a rough idle, some smoke: those are the symptoms when they appear, instead of a neat stop — and a misfilled diesel will usually take you onto it and some distance along before anything feels wrong at all.
The first sensible junction is the one to take. Switch off there, and leave the restarting alone. It alters what we bring, and so tell us when you ring: on a longer drive — anything approaching the under 25 miles to the nearest city — assume the petrol has been through the fuel filter, your pump and the injectors.
A little about Portrack
Portrack is a suburban area located on the riverside in County Durham, with a low elevation of around 4 metres. Portrack sits near several nearby places, including St Anns Hill, Newport, and Mount Pleasant, and is approximately 18.6 miles from the city of Durham. Portrack is characterized by its predominantly semi-detached housing stock, which is home to a population of around 1706 residents.
What we do when our technicians arrive with you around Portrack
- The responses alter the work, which is why our technicians ask before quoting: what got in, how much of it, and whether your motor has run.
- The polluted fuel comes out of your tank.
- What is remaining in the system should not be what created the issue, so the lines get purged and the fuel filter cleaned.
- Clean diesel goes in, and then your system gets primed.
- It is fired up with clean diesel in it, and our engineers make sure that it is running properly.
From there, you are ready to set off. We do all of this wherever the car has stopped, which means it never needs to be taken to a workshop, and when it has been caught quickly, it is very uncommon for there to be permanent damage.
A separate problem: AdBlue in a diesel tank around Portrack
Never fire it up: that opening instruction stands whether what got in was AdBlue or petrol. What changes is this fault itself. Petrol does two things to diesel: weakens it, and removes the protection the fuel system relies on. Rust and deposits are what a diesel tank gets instead, as AdBlue is urea in water.
Often the more serious of the two, AdBlue — and the detail sits on its own Portrack page. Both are ours to deal with.
Portrack costs for a petrol-in-diesel fuel drain
One price would not be honest here, as this is not one job. These are the things that shift it:
- Started? Driven? Either answer matters more than anything else on this list.
- Wrong fuel in, against what the tank takes — that ratio.
- The kind of fluid in the tank, petrol or AdBlue.
- Where is it? And can a van get to it and work there safely?
A clear answer rather than a range is what you get for telling us three things: the car, the quantity, and whether it has run. For the vehicle at home that's going nowhere and is not urgent, is fine too.
Portrack drivers ask us these about petrol in diesel
Fuel drains on a Portrack petrol station forecourt
Yes — forecourts are where a large part of this takes place. Our engineers work at Morrisons and the other forecourts locally routinely, with the station's agreement — tell us which one you're at when you phone and we'll tell you if we can work there.
A couple of litres of petrol in a diesel — too much?
It hinges on the proportion instead of the litres, and far more on whether your motor has run. A nearly empty tank with five litres in it, against a full one with the same five: distinct situations, certainly. Either way, the work needed comes down to one thing, which is whether the fuel system has had that mixture drawn through it.
I drove it after putting petrol in my diesel. Now what?
Switch off somewhere sensible, then keep it that way after you stop. Not restarting it is the single most valuable thing available to you now. Driving does shift the trouble out of that tank and into the pump and injectors, yes, and it stays salvageable far more regularly than drivers assume.
Is a fuel drain going to void my warranty?
A manufacturer's warranty survives a drain and flush done to a correct standard, which is no change at all. Running a diesel on petrol is the thing more likely to cause an argument with one, which is another good reason to leave the car turned off.
Adding two-stroke oil, then driving home
What petrol has diluted is not replaced by two-stroke oil, which is an old workaround for a distinct issue. So no. Petrol remains in that tank later on, whatever else goes in, and your pump gets no respite from it.
Does petrol in a diesel have to go to a main dealer?
No. Our engineers drain and flush the vehicle wherever it is, so there is no need to bring it to a franchised dealer.
You, and the car, still together?
Never switch it back on.
Turn it off somewhere safe and keep it off, if you have already driven it. This is recoverable from a lot more commonly than motorists assume, and a still, cold car is the best position to be in.
