Put Petrol in a Diesel Car in Barnes Cray?
If you have not started the engine as yet, do not. A fuel drain and nothing else is almost always what a car needs while the petrol is still sitting in that tank and your engine has not run, which is why it is the following few minutes that matter, not how much got in. Petrol in Diesel travels to the car wherever it has stopped in Barnes Cray or the remainder of Greater London, on the forecourt, by the roadside or on a private drive, and drains and cleans it there. One ring to us is enough: our technicians shall show you what happens next. Do that right away.
The first five minutes: petrol in a diesel
- Feed a petrol engine diesel and it will generally not run at all, so the driver stops there and so does the wear. Feed a diesel petrol and the engine starts, it ticks over, it pulls away — fine enough for a couple of miles. Motorists have that muddled, which is the part they get wrong about petrol in a diesel especially. So don't fire it up. And having started, do not rely on it: your fuel system is grinding as you drive.
- Two tasks, diesel: it burns, and on the way through it keeps that high-pressure pump and injectors greased. Petrol only handles the one. That is why the car's ignition stays off too — turn it on and you frequently prime that system, and that's petrol leaving the tank for exactly those parts.
- Never tip diesel on top to weaken it. A diesel fuel system won't handle petrol by percentage as that guidance suggests, and topping up clears nothing — it just leaves you a bigger tank of the same mix. The type makes no difference either: super unleaded is simply petrol.
- Stay where you are if you reasonably can. A motor that hasn't moved is the easiest one to sort out, and we would rather come to an awkward location than have it started. If you are stopped on the verge on Iron Mill Lane, switch those hazards on then keep the car there.
- Find out where you are before phoning. A postcode beginning DA1 4, and the name of whatever is next to you. Otherwise our van circles rather than arriving.
- Ring 0333 366 0103. Say what was put in, about how much, and if the car has run. These three answers determine the full call-out.
The journey in is what pulled thinned diesel through the pump. Standing still has pulled nothing. Petrol in a diesel Renault Megane, parked outside Slade Green all day, waits harmless in your tank whilst it waits. Phone us first — before your keys go in.
The phone call our technicians want runs like this: diesel Volkswagen Passat, a couple of litres of unleaded, done a couple of miles, now switched off outside Aldi. What we are actually asking is how much fuel the pump has drawn — not how long ago it was.
Somebody will advise you to move the car out of the gateway and deal with it later. Please don't. A misfilled diesel Nissan Qashqai on the zig-zags at Haberdashers' Crayford Primary is a hassle; the same car fired up three more times to be polite is a fuel system instead of a tank. Every restart primes your lines and pulls more petrol past the filter then into your pump. Leave it, let people complain, then ring us.
It will start. It will pull away just fine. That is the trouble, since a diesel on a diluted tank behaves normally whilst wearing down the components its fuel should be lubricating. So no, do not chance the trip home from Bird in Hand — leave the Ford Focus then call us.
A person sure of themselves will tell you to drain the vehicle then put fresh diesel in. Half right, that. Try it on a diesel Volvo XC60 near Propella and the engine will start — which is exactly why it sounds like sense. Here is the problem: there's petrol left in the fuel filter and the feed lines, and the first thing your engine does is draw it back through the pump once more. Draining a tank achieves nothing about fuel that already left the tank. Call us. The system gets cleaned, the filter comes off where there's one worth removing, and that is what separates a fixed motor from one that only starts.
At the forecourt: removing petrol from the diesel
Pumps are where this job usually starts, and where a good chunk of that closes. Still at Shell? Then that is typically where it gets done. Petrol station forecourts are normal for us, with the consent of the site.
The forecourt is the only location it is caught before the engine has started. Everywhere else — a car park, a private drive, a lay-by — the car was started and moved to get there, which means fuel was drawn from that tank, through the fuel filter then into the high-pressure fuel pump. That is not a catastrophe, and we can still sort it out where it stands. It does mean your lines and the filter need rinsing as well as that tank, and that is settled by the few seconds between checking the till receipt and reaching for your key.
Away from the petrol pump, the next driver can get through — so yes, let the staff help you roll the vehicle. Well worth doing. Cranking it over four car lengths? Never.
Barnes Cray plus the villages near it
Crayford, North End, Slade Green, Dartford Marshes, Colyers — each of those on our journeys that bring us out to Barnes Cray itself, a residential suburb.
If yours isn't on this list it doesn't mean we don't come — there are pages for nearly all places in Greater London, and the ones listed above are just the immediate neighbours. Call us to check rather than assuming — borders especially, and wherever the satnav might get wrong.
Look at our map for the area covered on this page. Roadside, forecourt, drive, car park: the lot is territory we work on, and none of it asks your vehicle to come to us.
Barnes Cray: stranded wherever you pulled up
Not everybody has the opportunity to pull over somewhere safe. Hazards going in a lay-by somewhere, or stopped on the verge of Thames Road since you noticed after setting off — our engineers take that call often enough that it is the usual kind.
Out of your car while it is not safe to sit there, with it when it is. It will often oblige. A diesel running on petrol limps along very willingly, and that is the trouble: restart it to get to somewhere safer and the mix goes further into the fuel system with every mile driven. However difficult the place, it is no bother for us to get to it, and that is far better for your car than carrying on.
Driven it already? Pull over, then read below
This is where your M25 comes in — under 3 miles from Barnes Cray. Some way along, and onto it in the first place: a wrongly fuelled diesel will frequently manage both before anything feels wrong. What you get then is rarely a clean stop. Power falls away, the idle goes uneven, and there may be some smoke.
Come off at the next safe junction, turn off, and don't start the car to move it. On a longer trip — anything near the under 15 miles to the nearest city — take it the petrol has been through the fuel filter, your pump and your injectors, and tell us when you ring. It affects what our engineers bring.
A bit about Barnes Cray
Barnes Cray is a suburban area in the London Borough of Bexley, situated on the banks of the River Cray. Barnes Cray has a relatively low elevation of around 9 metres above sea level and is located near the towns of Crayford and Dartford. Barnes Cray is characterized by its semi-detached housing stock and is a residential community on the outskirts of London. Barnes Cray is close to several nearby places, including North End and Slade Green.
The call-out in Barnes Cray, step by step
- The replies change the work, which is why we ask before quoting: what got in, how much of that, and whether the engine has run.
- Our technicians drain the tank of the contaminated mixture.
- What is remaining in the fuel system should not be what created the problem, so your fuel lines get cleaned and the filter cleared.
- Clean diesel goes in, and then the fuel system gets primed.
- It's run with new diesel in it, and our technicians make sure that it is running properly.
That leaves your car ready to drive away. All of this is done where the car is, so it never has to be taken to a workshop, and when it has been noticed quickly, permanent damage is very unusual.
AdBlue in a diesel tank around Barnes Cray is a different matter
The issue is not the same, though the first step is — do not crank it — if what got in was AdBlue instead of petrol. Petrol does two things to diesel: thins it, and strips out the protection your fuel system relies on. Urea dissolved in water, AdBlue, and in a diesel tank that leads to corrosion and build-up.
Both are ours. There's a separate Barnes Cray page for AdBlue removal, with the details on it — including the reasons it usually turns out to be the worse of the two.
How much is a petrol-in-diesel fuel drain around Barnes Cray?
Truthfully, no single price belongs on a page like this. This job changes. Here is what changes it:
- Started? Driven? Either answer counts more than anything else on this list.
- How much of the wrong fuel was put in, judged against how much the tank can hold.
- Whether it's unleaded or AdBlue.
- Whether a technician can sensibly reach the vehicle and work on it, which rests on where your vehicle is.
Tell us what the vehicle is, how much went in, and whether your motor has run. A straight answer comes back, not a range. Not time-critical, with your car at home and going nowhere? Then is fine.
Petrol in diesel questions from Barnes Cray drivers
I'm on a forecourt in Barnes Cray. Can you drain the vehicle on the spot?
Yes — forecourts are where a large share of this gets done. Tell us which one you are at when you ring and we'll tell you whether our technicians can work there. With the owner's consent our engineers work at Esso and the other forecourts nearby all the time.
Is there a safe quantity of petrol in a diesel?
Whether your motor has run matters much more, though the ratio matters too, rather than the litres. Five litres into a nearly dry tank is not five into a full one, no. But both land on the same question in the end: has that mix been pulled right through, or has it not?
I put petrol in my diesel and drove it. Now what?
Switch off somewhere sensible, and keep it that way after you stop. Driving takes the issue along — out of that tank, into your pump and injectors. Motorists fear it a good deal more than the recovery rate warrants, mind. The one really useful thing left to you isn't restarting it.
Is a fuel drain going to void my warranty?
A manufacturer's warranty outlasts a drain and flush done to a good standard, which is no alteration at all. What is likelier to start a disagreement is a diesel that has been run on petrol. One more reason for the engine to remain off.
Adding two-stroke oil, then driving home
No. Two-stroke oil is an old remedy for a distinct fault and it doesn't put back what petrol has diluted. Your pump still has to put up with it, because your tank still has petrol in it later on.
Does petrol in a diesel have to go to a main dealer?
No. Our technicians drain and clean the vehicle wherever it is, so there is no need to take it to a franchised dealer.
Waiting next to it?
Never turn it back on.
Driven it already? Then somewhere sensible, stop, switch off, and no restarting the car later on. Cold and stationary, a car is in the best place available — and motorists fear this a lot more than the recovery rate warrants.
