The Sands: Put Petrol in a Diesel Car?
If you have not turned on the motor yet, do not. A fuel drain and nothing more is almost always what a car requires while the petrol is still sitting in your tank and the motor has not yet been started, which is why it is the coming few minutes that matter, not how much went in. Petrol in Diesel goes to your car wherever it has ended up in The Sands or the rest of Durham, on the forecourt, at the roadside or on a driveway, and drains and cleans it there. Ring us before all else begins, so you'll hear what happens after that.
Your first five minutes: petrol in a diesel
- As you drive, the pump and your injectors wear. That is why you never start it, and why you don't believe it once it has started. The catch about petrol in a diesel specifically — the point people get wrong — is that it drives off normally for the first mile or two. Diesel in a petrol engine generally will not run at all, which stops the person and stops the wear with them. This one lets you drive on.
- Diesel combusts, and before it burns it protects — your high-pressure fuel pump, the injectors. Petrol handles only the burning. So leave your ignition off as well: switching it on is usually all it takes to prime the system, and priming carries petrol from your tank into just those components.
- Topping up takes out nothing. It hands you a bigger tank of the same mixture, because a diesel fuel system does not handle petrol by percentage in the way that advice implies — so don't put diesel on top to dilute it. Octane is irrelevant too: super unleaded is petrol.
- We would rather drive to a difficult location than have it started — so if you sensibly can, sit tight. Nothing is quicker to handle than a motor that has never shifted. On the verge on The Sands, that means hazards on and keep the vehicle.
- Before you call, get your whereabouts. Anything nearest to you with a label on it, plus a postcode beginning DH1 1 — that's what decides whether our van arrives or circles.
- Ring 0333 366 0103. Tell us what got in, about how much, and if the car has run. These three facts decide the full visit.
Pump-side drains for petrol in a diesel
Plenty of the work begins at a pump, which means a good share of it gets finished on site. Still at Esso? Then that is typically where it gets done. Station forecourts are everyday for us, with the permission of the site.
At the forecourt, it is caught with the engine never started, and no place else manages that. Fuel drawn out of your tank and through the fuel filter, right to your high-pressure pump, is what occurs when your engine is switched on and the vehicle is moved to where it is now: the car park, the driveway or the lay-by, anywhere other than the forecourt. So the flush covers the fuel filter and the fuel lines along with the tank. That is still not a catastrophe, and we sort it out where the vehicle is. What settles it is whether the key was turned in the seconds after the till receipt was read.
Wheel it out of the way if the attendants offer, and they normally will. The next driver gets past the petrol pump, and that is worth doing. Cranking it to move four vehicle lengths isn't.
We're in car parks like the one at Tesco Extra all the time, and it is almost never your fuel that complicates them. It is that bay. Motors both sides. Trolleys stacked up behind. At times a height limit at the entrance, which settles whether a technician gets to you at all. So say how boxed in you are when you call, and which way the car is facing. If there is no space to work next to that Skoda Octavia, our technicians roll it without your engine. That isn't fussiness over a handful of seconds: starts prime things, mixture comes out of the tank toward your pump, and a motor shuffled twice for a roomier space is gradually a bigger job than one nobody touched.
Shift the car out of the gateway and sort it out later — that is what a passer-by will say, and it is wrong. Parked on the zig-zags at St Oswald's Church of England Aided Primary and Nursery School, a wrongly fuelled diesel Peugeot 308 is an inconvenience and nothing worse. Fired up three more times for politeness, it's no longer a tank problem but a fuel system one, because priming happens with every start and more petrol goes past the filter on to your pump. Let them moan. Call us.
Easy job, this one — till someone takes it home. A diesel Mercedes C-Class parked by Drunken Duck with petrol in your tank loses nothing by standing there overnight, so leave it and call us once it is light. Expect a question about the drive there, though. Short and chilly is exactly where petrol fails to burn, and what won't burn can work past the piston rings and into the sump.
Injection pressure is the part being lost. Petrol dilutes diesel, and weaker fuel leaks past the precision parts that are supposed to build that pressure, so the farther a diesel Audi A3 went, the less well it held. Fine on the way out and gutless on the way back is how the trip to the green space at the edge of the village went, then, and that tank is the place to look. Pull over somewhere sensible, switch off then ring us.
Clattering? Ragged idle? White smoke, throttle gone soft? That's your misfilled Vauxhall Astra, a diesel, saying what's wrong with it. Stop wherever you happen to be, possibly close to Freeman's Quay Leisure Centre, then leave the restarting alone.
Service near The Sands
As a residential suburb, The Sands sees a regular visit, and the places round about go along on the same trip: Durham and Western Hill, North End and Gilesgate, Aykley Heads.
Not on the list? That means nothing. The names above are simply the nearest few, and most towns around Durham have a page of their own somewhere on our site. Contact us to enquire rather than assuming, particularly where you're on the boundary or somewhere your satnav struggles with.
The patch the page spans appears on our map. Every bit of it is territory our technicians cover: a kerbside, a forecourt, a drive, a car park. You do not move your car anywhere.
The Sands: stranded wherever you parked
Not everyone gets a safe spot to pull in. Set off, then realised? Finished up by the verge beside Providence Row, or sat in some lay-by with your hazards on? That is a common call here. Not a rare one.
Out of your car while it is not wise to be inside, with it if it is. Every mile a diesel obliges you for on petrol pulls that blend further into the fuel system — and oblige it frequently will, which is why your motor doesn't get restarted to limp somewhere better. Pressing on does your car far more harm than a van driving out to an inconvenient spot, and that is no problem for us.
A few miles on petrol in a diesel: what now?
This is where the A1(M) comes into it — under 3 miles away from The Sands. A drop in power, a lumpy idle, some smoke: those are the symptoms when they come, rather than a tidy stop — and a wrongly fuelled diesel will often get you onto it and some distance along before anything seems wrong at all.
The next sensible exit is the one to take. Switch off there, and leave the restarting alone. Assume the worst of it on a long run. Anything approaching the under a mile to the closest city, and the petrol has been through the fuel filter, through your pump, through your injectors. Tell us when you call. What we bring differs.
Where is The Sands?
The Sands is a suburban area located on the riverside in County Durham, England, with a mix of terraced housing and a population of around 3816 residents. The Sands sits near the city of Durham, being only 0.4 miles away, and is part of the wider North East region. The Sands has an elevation of 35 metres and is situated near other local places such as Western Hill and North End. The Sands is connected to the rest of the country, with London being approximately 233.9 miles away.
What our technicians do when our engineers reach you around The Sands
- Three things get established before any price — the fuel that was put in, the amount, and if anything has been run since. Each answer changes the work.
- Your tank is cleared completely.
- Lines cleaned, filter cleared. Whatever is left after that isn't the thing that caused the issue.
- The fuel system gets bled, on new diesel.
- We turn it on and confirm it runs smoothly on new diesel.
At that point it's ready to set off. Permanent damage is very rare when it has been caught quickly, and because all of it is done where your car is, it never has to be taken to a workshop.
AdBlue in your diesel tank by mistake, in The Sands?
If what was put in was AdBlue instead of petrol, the first instruction is the same — do not crank it — but the issue isn't. Petrol does two things to diesel: dilutes it, and strips out the lubrication the fuel system relies on. AdBlue? Urea dissolved in water. Put that in with your diesel and you get rust instead, plus build-up.
Both are ours. There's a separate The Sands page for AdBlue removal, with the detail on it — including the reasons it often turns out to be the worse of the two.
The Sands pricing for a petrol-in-diesel fuel drain
What changes the figure is listed below, since the job isn't one job and our engineers cannot frankly put a single number on this page.
- Has it been started or driven? Nothing else counts for as much.
- How much of the wrong fuel was put in, judged against how much that tank holds.
- The sort of liquid in the tank, unleaded or AdBlue.
- Where your vehicle is, and whether a van can safely reach and work on it.
Tell us what the car is, how much went in, and whether the motor has run. A clear answer comes back, not a range. For your car at home that is going nowhere and isn't time-critical, is fine too.
Things we get about petrol in diesel in The Sands
At a petrol station around The Sands, can you do a fuel drain there?
Yes, and it's where a good share of this work gets done. Regularly, provided the site agrees: Tesco, plus every other forecourt nearby. Say on the phone where precisely you have stopped. Whether our engineers can work in that place is something our technicians answer there and then.
Is there a sensible amount of petrol in a diesel?
Proportion settles it instead of litres — and more than either, whether the motor has run. A nearly empty tank with five litres in it, against a full one with the same five: separate situations, definitely. Either way, the work required comes down to one thing, which is if the system has had that blend sucked through it.
Petrol in my diesel, and I have driven the vehicle
Pull over somewhere safe, turn off, then keep it off. Driving moves the problem along — out of that tank, into the pump and injectors. Drivers fear it a good deal more than the recovery rate warrants, mind. The one genuinely useful thing left to you is not restarting the vehicle.
Will a fuel drain void my warranty?
No. Carried out properly, emptying and flushing is no modification at all, and the warranty from your manufacturer is unaffected by it. An argument over a warranty is likelier to come from running a diesel on petrol — so leave it switched off.
Can I just add two-stroke oil and drive home?
No. It belongs to a distinct problem from a bygone era, and petrol has diluted something no oil of that kind puts back. Later on? Still petrol in your tank, and a pump that has to cope with the stuff.
Do I need a main dealer for petrol in a diesel?
There is no need to bring it to a dealership, because our technicians drain and flush the vehicle wherever it is.
Waiting next to it?
Leave the engine switched off.
Switch it off somewhere safe and leave it off, if you have already driven it. A stationary, cold car is the best position to be in, and this is recoverable from far more regularly than drivers assume.
