Put Petrol in a Diesel Car in Harrowby? Don't Start It
If you have not started the engine yet, don't. A fuel drain and nothing else is nearly always what a car requires while the petrol is still inside that tank and your engine has not yet turned over, which is why it is the following few minutes that matter, not how much got in. Petrol in Diesel goes to the vehicle wherever it has stopped in Harrowby or the remainder of Lincolnshire, on the forecourt, at the roadside or on a private drive, and drains and cleans it there. Just one ring to us is plenty: we shall tell you what happens after this. Make it first.
What now? Petrol in a diesel, step by step
- Whenever you drive, the pump and the injectors wear. This is why you do not crank it, and why you never believe it once it has started. The thing about petrol in a diesel especially — the bit motorists get wrong — is that it drives off fine for the first mile or two. Diesel in a petrol motor normally will not run at all, which stops the person and stops the harm with them. This one lets you keep going.
- Two things, diesel: it ignites, and on the way through it keeps that injection pump and injectors oiled. Petrol only handles the one. Which is why your ignition stays off also — turn it on and you commonly prime that system, and that is petrol leaving that tank for precisely those parts.
- Don't thin it. Diesel added on top clears nothing, so all you get is more of what was already there, because percentage is not how a diesel fuel system tolerates petrol. Super unleaded? Just petrol. The type makes no difference.
- Our team would much rather drive to a tricky place than have it started — so if you sensibly can, stay put. Nothing is simpler to sort than a car that has never shifted. On the verge on Hall Lane, that means hazards on then leave the vehicle.
- Check where you are before ringing. A postcode beginning NG31 9, and the name of whatever is nearest to you. Otherwise the technician circles instead of turning up.
- Ring 0333 366 0103. Say what was put in, about how many litres, and if your car has run. Those three answers settle the entire job.
Can petrol be taken out of a diesel at the forecourt?
Plenty of this work starts at a pump, meaning a good portion of that is done at one. We operate on garage forecourts routinely, with the station's agreement, and so if you are still at BP that's typically where the drain gets done.
A filling station is the only location it can be spotted before the motor has run. Everywhere else — a car park, a drive, a lay-by — your car was started and moved to get there, which means fuel was pulled from the tank, through the filter then into the high-pressure fuel pump. That's not a disaster, and our technicians can still deal with it where it stands. It does mean the fuel lines and the filter need flushing as well as the tank, and that is settled by the few seconds between checking your receipt and reaching for your key.
Push the vehicle out of the way if the attendants suggest it, and they generally will. The next driver gets by the pump, and that is worth doing. Starting the car to roll four vehicle lengths isn't.
Will our technicians reach your end of Harrowby?
Cherry Orchard, Cold Harbour, Londonthorpe, Manthorpe, Spittlegate — each of them on the rounds that bring us across to Harrowby as well, a small village.
If yours isn't on the list it does not mean we don't come — there are pages for most places in Lincolnshire, and the ones named above are simply the immediate neighbours. Phone and ask instead of assuming, particularly when you're on a border or anywhere the satnav misreads.
The patch this page includes sits on this map. We work by the road, at forecourts, on driveways and in car parks throughout all of that, and your car does not need to move to us.
Kerbside call-outs in Harrowby
Not everyone finds a sensible place to pull over. Hazards on at a lay-by somewhere, or stopped on the verge on Harrowby Lane as you noticed after setting off — we take that call so often that it is the normal kind.
Whether you wait by your car or keep clear of it hangs on whether staying there seems safe. It will usually oblige. A diesel running on petrol limps along quite willingly, and that is the trouble: restart the vehicle to reach somewhere better and that mix goes further into the system with every mile covered. However difficult the place, it's no bother for us to come to it, and that is much better for the car than driving on.
What we'll want to know is whether the trip there was brief and chilly, since that's where petrol is slowest to burn properly — and what does not burn can work past the rings then into the oil. Right up to the moment someone drives it home, a diesel Peugeot 3008 standing in the parking area outside the pub in the village carrying a tank full of petrol in it is an easy job. Nothing worsens as it stands, so park the car there overnight and ring us next morning.
None of it is the engine failing. That's the bit worth hearing, and it is why the ordinary Hills and Hollows call ends better than it sounds: a diesel Mercedes E-Class drives out there without complaint, comes back with the power gone, the idle uneven and perhaps a little smoke, and the cause is the fuel no longer acting like diesel. Diesel has to be thick enough to seal the close-fitting parts it flows through; petrol thins it; and a diesel injection system is hydraulic as much as chemical, needing the fuel to hold pressure rather than only to burn. So pressure that should build then stay built bleeds past clearances, delivery turns up poorer and later and less even than built, and all of that stops once your fuel is put right.
Hardly ever the trouble, the place. On-street is the most common place our engineers work, and a narrow parking bay is far preferable to a motor that has been driven somewhere more handy. What does help, when you phone from near The Environcom Stadium (Harrowby United FC), is three things: the side the filler is on, whether our van can park beside without blocking the road, and if anything has run since you filled up. Then the Vauxhall Astra gets drained, the filter changed where a workable one exists, the lines rinsed and fresh fuel put through the whole circuit — because by now the worst of that is in your lines, not the tank.
Most of these happen somewhere unfamiliar, and the cause is mechanical not careless — practically no resistance meets a slimmer petrol nozzle entering a modern diesel filler neck. Two days into a diesel Audi A6, a fill-up close to The Church of the Ascension that you didn't think about? Phone us from where you are. Courtesy and hire cars go further before anybody clocks it, and the further they go, the more petrol arrives at the fuel injectors.
Repaired and starting are not the same thing, and the difference is your circuit: our engineers flush it, and take the fuel filter off where there's a serviceable one. Compare that with the sure of themselves advice you will get — drain it, refill with new diesel. Half right. Do precisely that to a diesel Kia Sportage near Church Hall and it will start, which is exactly why the suggestion sounds reasonable. Then the engine pulls the petrol left behind in the filter, and in the feed lines, straight back through the pump, because emptying a tank does nothing whatever about fuel that has already left it. Ring us instead.
So you've driven it? Petrol in a diesel over a few miles
This is where the M1 comes into it — under 50 miles from Harrowby. A drop in power, a lumpy idle, smoke: those are the signs when they appear, instead of a clean stop — and a wrongly fuelled diesel will usually take you onto it and some way along before anything seems wrong at all.
Pull off at the first safe exit, switch off, and do not start the car to reposition. Assume the worst of it on a long run. Anything approaching the under 25 miles to the closest city, and the petrol has been through the fuel filter, through the pump, through the fuel injectors. Tell us when you phone. What our engineers bring alters.
All about Harrowby
Harrowby is a small locality in Lincolnshire, situated inland at an elevation of around 125 metres. Harrowby lies approximately 22 miles south of Lincoln and 99 miles north of London, near the villages of Cherry Orchard and Londonthorpe. Harrowby has a population of around 865 people, predominantly living in semi-detached housing. Harrowby is characterized by its quiet, residential atmosphere, with nearby Cold Harbour also part of the local community.
When we get to you around Harrowby: what happens
- The responses shape the work, which is why we ask before pricing: what got in, how much of that, and if the motor has run.
- We empty the tank of all the tainted fuel.
- Fuel lines are purged through and your filter cleaned, leaving nothing in your system that caused any of this.
- The system gets bled, on clean diesel.
- It is fired up with clean diesel in it, and our engineers make sure that it is running properly.
After that it's ready to pull away. There's no need for a workshop at any point, as the work is all done where the vehicle is, and when it is spotted quickly, permanent damage is very unusual.
AdBlue in the diesel tank instead, in Harrowby?
The issue is not the same, though the first rule is — do not crank it — if what was put in was AdBlue rather than petrol. Thinned diesel, and no protection left for your fuel system that depends on it. That is petrol. Rust and deposits are what a diesel tank gets instead, because AdBlue is urea in water.
Our technicians cover both, and AdBlue removal around Harrowby has its own page with the details — including why it is usually the more serious of the two.
What a petrol-in-diesel drain costs around Harrowby
What shifts the price is set out below, since this job is not one job and our engineers can't honestly put a single price 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 your tank holds.
- Whether it was unleaded or AdBlue.
- Where is it? And can our van reach it and work there sensibly?
A clear answer rather than a range is what you get for telling us three things: your car, the amount, and if it has run. Not urgent, with the vehicle at home and going nowhere? Then works.
Questions our technicians get about petrol in diesel around Harrowby
Fuel drains on a Harrowby petrol station forecourt
Yes — forecourts are where a large share of this takes place. Tell us which one you are at when you phone and we'll tell you if our engineers can work there. With the owner's permission our technicians work at Sainsbury's and the other forecourts nearby all the time.
A few litres of petrol in a diesel — too much?
Litres are not the measure. Ratio is, and much more than either, it counts whether anything has been run. Five litres in a nearly empty tank is a separate matter from five in a full one — but either way, the thing that determines how much work is needed is if that mix has been sucked through the fuel system.
I put petrol in my diesel and drove the vehicle. Now what?
Switch off somewhere sensible, then keep it that way after you stop. Driving is what shifts the problem from that tank into your pump and injectors — but it is fixable much more often than drivers fear, and the single most valuable thing you can do now isn't restart it.
Fuel drains and manufacturer warranties
A drain and flush carried out properly is not a modification and doesn't void a manufacturer's warranty. Another reason to leave it switched off: running a diesel on petrol is the thing more likely to cause a dispute with one.
Two-stroke oil in your tank, and then home?
No. It belongs to a separate problem from a bygone era, and petrol has diluted something no oil of that kind restores. That tank still has petrol in it afterwards, and the pump still has to live with it.
A main dealer for petrol in a diesel — needed?
Wherever your car is, we drain and clean it there, so a visit to the main dealer doesn't come into it.
You, and your car, still together?
Don't switch it on again.
Already driven it? Then pull over somewhere safe, switch off, and let the vehicle remain that way. A still, cold vehicle is the best position to be in, and this is recoverable from far more regularly than motorists assume.
