Petrol in a Diesel Car in Shortlands
If you have not started your engine yet, do not. A fuel drain and nothing else is almost always what a motor needs while the fuel is still sitting in that tank and the engine has not yet run, which is why it is the coming few minutes that matter, not how much went in. Petrol in Diesel comes to your car wherever it has stopped in Shortlands or the rest of Greater London, on the forecourt, at the roadside or on a driveway, and drains and flushes it there. We shall explain what the next step will be. Ring us — it goes ahead of all else.
What to try next about petrol in a diesel
- Give a petrol engine diesel and it will normally refuse to run at all, and so the person stops there and so does the damage. Give a diesel petrol and the engine starts, it idles, it pulls away — all right for a few miles. Most people have that reversed, which is the part they get wrong about petrol in a diesel especially. So never start it. And once started, never depend on it: the fuel system is wearing whenever you drive.
- Leave the ignition alone as well. Diesel has two jobs: it burns, and before it ignites it greases the high-pressure pump and those injectors. Petrol does the first but not the second. Switching your ignition on is usually enough to prime that system, which carries that petrol out of your tank then into exactly those parts.
- That guidance assumes a diesel fuel system accepts petrol by percentage. It doesn't. Tip diesel on top and nothing at all is removed; what you get is a fuller tank of the same mix. And no, the grade makes no difference — super unleaded is simply petrol.
- Stay where you are if you safely can. A motor that has never moved is the quickest one to deal with, and we'd much rather get to a difficult location than have it started. If you are parked on the verge on Durham Road, put those hazards on then keep the car there.
- Have your location prepared before you phone. A postcode that starts BR2 0 and whatever is nearest to you with a sign on it is the difference between our van arriving and a van circling.
- What went in, roughly how much, plus whether the engine has started — these three replies settle the whole call-out. Call 0333 366 0103 then tell us.
Can petrol be taken out of a diesel on the forecourt?
Plenty of the job begins at a forecourt, so a big share of that ends up done at one. Still at Esso? Then that's typically where it happens. Station forecourts are normal for us, with the consent of the site.
At the forecourt, it is halted with the engine never fired, and nowhere else manages it. We 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, your car has been started and moved there, and that drew fuel through your filter then into the high-pressure fuel pump, all the way from your tank. None of that is a catastrophe, although the flush then has to reach past that tank to the fuel lines and your filter, and the few seconds between checking your receipt and going for the keys are what decide that.
Clear of the pump, the next motorist can get past — so yes, let the attendants help you roll the vehicle. Very much worth it. Moving the car four bays doesn't merit starting the engine.
We're in car parks like the one at Lidl a lot, and it's hardly ever the fuel that complicates them. It is the bay. Motors both sides. Trolleys stacked up behind. Occasionally a height bar at the entrance, which determines whether our van reaches you at all. So tell us how hemmed in you are when you phone, and which way the car is facing. If there is no clearance to work next to the Skoda Octavia, we move it without your engine. That isn't pedantry over a few seconds: starts prime things, blend comes out of that tank on to the pump, and a car shuffled twice for a roomier bay is quietly a harder job than one nobody touched.
Shift the vehicle out of the gateway and fix it later — that is what someone will say, and it's wrong. Parked on the zig-zags by Harris Primary Academy Shortlands, a wrongly fuelled diesel BMW 3 Series is a hassle and nothing worse. Fired up three more times for good manners, it's no longer a tank issue but a fuel system one, because priming happens with every start and more petrol goes through your filter toward the pump. Let people grumble. Give us a call.
A diesel Nissan Qashqai parked in the car park by Shortlands Tavern holding a tank of petrol in it is a simple job, right up till somebody takes it home. Park the vehicle there overnight then ring us in the morning. Nothing degrades while it sits. What we'll want to know is whether that drive there was short and chilly, because that is where petrol is least able to burn correctly — and whatever won't burn can get past the piston rings and into the engine oil.
Off the forecourt, receipt read, a couple of hundred yards, left close to St Mary, Shortlands. For a diesel Ford Focus whose motor has turned, that's about the best version there is. Ring us, then let the vehicle stand with your ignition alone. Short assists, really — but a start is a start and a drive is a drive, and your filter has had thinned fuel through it, and so has the pump. Which is why the lines get purged and not just that tank drained.
Authorisation first, where there is a hire firm or a company behind the vehicle — some agreements insist on it, and settling that beforehand saves a great deal of time later. After that, ring us about your diesel Mercedes A-Class by Amphitheatre. You'll not know how full your tank was. Scarcely anybody does, two days into a vehicle, and it gets worked out there anyway. Our technicians ask because the harm petrol does in a diesel is proportional: a few litres in an almost empty tank make a much stronger mix than the same few in a full one, and since petrol is engineered to resist igniting under pressure, which is exactly what a diesel relies on, the stronger it gets the more your engine knocks and smokes and flattens off.
Places our vans serve in Shortlands
Bromley, Bromley Park, Widmore, Park Langley, Sundridge — every one of these on the runs that carry us out to Shortlands itself, a residential suburb.
There are pages for nearly all places in Greater London, and the ones named above are merely the closest neighbours — so yours being absent from the list says nothing about if our engineers come. Close to the boundary, or somewhere your satnav can't find? Call us and ask instead of presuming.
The ground this page includes sits on this map. We operate roadside, at forecourts, on driveways and in car parks over all of it, and the car does not need to move to us.
Shortlands: stuck wherever you pulled up
Not everyone gets the opportunity to pull in somewhere suitable. If you realised after setting off and finished up by the verge beside Hillside Road, or at a lay-by somewhere with the hazards flashing, that is a routine call for us rather than an unusual one.
Out of the vehicle while it is not sensible to be there, by it if it is. Do not restart it to get to a safer spot. It will go — a diesel on petrol usually obliges — and each mile of obliging drags that mixture deeper into the system. We will bring the van to a tricky place without any trouble, and for your car that is far better than carrying on.
Run it already? Pull over, and see this
Here is where your M25 comes into it — under 10 miles from Shortlands. Some way along, and onto it in the first place: a misfilled diesel will often manage both before anything seems wrong. What you get then is rarely a neat stop. Power drains away, the idle gets uneven, and there may be smoke.
Come off at the next sensible exit, turn off, and never start it to reposition. Long drive? Anything close to the under 10 miles to the closest city and you should presume the lot — filter, pump, injectors, all of it reached by the contamination. Say that on the call, since it changes what goes in our van.
Shortlands itself
Shortlands is a suburban area in the London Borough of Bromley, situated on the banks of the River Ravensbourne. Shortlands sits at an elevation of around 42 metres, with a mix of residential and commercial properties, predominantly flats. Shortlands is located near the towns of Bromley and Widmore, and is close to Bromley Park. Shortlands has a population of approximately 9190 residents.
What our technicians do when our technicians reach you in Shortlands
- The replies shape the work, which is why our technicians ask before giving a price: what got in, how much of that, and whether your motor has run.
- We empty that tank of the tainted fuel.
- We rinse your fuel lines and clean your filter, so what is remaining in your system isn't what started the trouble.
- We put clean diesel in and bleed the fuel system.
- Once it's turned on, our technicians confirm it runs properly on new diesel.
From there, you are ready to drive away. Our engineers do everything wherever the car has ended up, which means it never has to go to a workshop, and if it has been spotted quickly, it is very rare for there to be permanent damage.
A different matter: AdBlue in a diesel tank in Shortlands
AdBlue rather than petrol? Then the first step is unchanged — your engine stays off — whereas the problem underneath it's a distinct one altogether. Petrol does two things to diesel: weakens it, and removes the protection your fuel system relies on. Urea in water, AdBlue, and in a diesel tank that leads to corrosion and build-up.
Both are ours. There's a separate Shortlands page for AdBlue removal, with the full story on it — including the reasons it frequently turns out to be the worse of the two.
Paying for a petrol-in-diesel fuel drain in Shortlands
One figure would not be fair here, because this is not one job. These are the things that shift it:
- Whether your engine has been run or driven. This is the key one.
- Wrong fuel in, against what the tank holds — that proportion.
- The kind of liquid in the tank, petrol or AdBlue.
- Where is it? And can a van reach it and work there safely?
Tell us your car, the amount and if it has run, and you'll get a firm answer instead of a range. For the car at home that is going nowhere and is not time-critical, is fine too.
Shortlands motorists ask us these about petrol in diesel
Fuel drains on a Shortlands petrol station forecourt
Yes, and it is where a fair portion of this work gets done. Routinely, provided the site agrees: BP, plus every other forecourt nearby. Say on the phone where precisely you have stopped. Whether we can work in that spot is something we answer straight away.
A few litres of petrol in a diesel — too much?
Whether your motor has run matters far more, though the ratio counts too, instead of the litres. 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 mixture been sucked right through, or has it not?
I drove it after putting petrol in my diesel. What next?
Somewhere safe, then stop, then turn off and leave it off. Not restarting it is the single most valuable thing available to you now. Driving does shift the problem out of your tank and into your pump and injectors, yes, and it remains fixable a lot more regularly than motorists expect.
Is a fuel drain going to void my warranty?
It is not a change, and so a drain and flush carried out correctly doesn't cancel a manufacturer's warranty. Another reason to leave it turned off: running a diesel on petrol is the thing likelier to cause a disagreement with one.
Can I just add two-stroke oil and drive home?
No. It belongs to a distinct issue from a different era, and petrol has thinned something no oil of that kind puts back. The pump still has to cope with it, as your tank still has petrol in it afterwards.
Does petrol in a diesel have to go to a main dealer?
There is no need to bring it to a main dealer, since our technicians drain and flush the vehicle wherever it is.
Still with your vehicle?
Your engine remains off.
Already driven it? Then stop somewhere safe, switch off, and let the vehicle remain that way. A parked, cold motor is the best position to be in, and this is recoverable from much more frequently than motorists assume.
