Put Petrol in a Diesel Car in Strand? Don't Start It
If you have not fired up the engine yet, don't. A drain and nothing more is nearly always what a vehicle needs while the petrol is still sitting in the tank and the engine has not yet been started, which is why it is the next few minutes that count, not how much got in. Petrol in Diesel comes to the car wherever it has ended up in Strand or the remainder of Greater London, on the forecourt, at the roadside or on a drive, and drains and cleans it there. One call our way is plenty: our engineers shall tell you what happens after this. Try it first.
What now? Petrol in a diesel, in turn
- While you drive, your pump and your injectors wear. That's why you don't start the vehicle, and why you never rely on it once it has started. The trick about petrol in a diesel specifically — the part drivers get wrong — is that it drives away fine for the first mile or two. Diesel in a petrol engine typically won't run at all, which stops the motorist and stops the harm with them. This one lets you carry on.
- Diesel combusts, and before it ignites it greases — the high-pressure fuel pump, those injectors. Petrol handles only the burning. So leave the ignition alone as well: switching it on is frequently enough to prime the system, and priming moves petrol from the tank into precisely those components.
- Do not pour diesel on top to thin it. A diesel fuel system will not tolerate petrol by percentage as that advice implies, and topping up takes out nothing — it only gives you a larger tank of the same mixture. The grade makes no difference either: super unleaded is just petrol.
- A vehicle that has never shifted is the quickest one to sort, so stay where you are if you sensibly can. Parked on the verge on Langley Street? Hazards on, and leave it there. A tricky place works for us better than a started motor.
- Before you ring, work out your position. Anything closest to you with a label on it, plus a postcode beginning WC2E 9 — that is what determines whether our van arrives or circles.
- Phone 0333 366 0103. Let us know what was put in, approximately how many litres, and whether the car has run. These three replies shape the full call-out.
Quarter past eight, a fast fill-up on the drive in, and you realise at about eleven — by which time the diesel Volkswagen Passat has been standing outside London Charing Cross for three hours. Phone us and keep it just where it is. The trip in is the thing that is key here, since diesel does two jobs on its way through an engine: it burns, and before it burns it greases its high-pressure pump and those injectors. Petrol manages the first and not the second. So those couple of miles were travelled with the pump working on a liquid that had lost a great deal of the protection it is built around — which is why the question our engineers ask is how far you travelled, not how long your car has been sitting.
The complicated part is the bay, not your fuel. Motors either side of you, a trolley shelter behind, and now and then a height limit on the way in that decides whether a van can reach you at all — so when you phone from a car park like the one outside M&S Food, mention how much space there is round you and which way round the car is. Those our technicians cover regularly. Should there be no room to work alongside the diesel Renault Clio, it gets shifted with your engine off, and not out of pedantry over a handful of seconds of running: priming takes place at every start, more of that blend exits your tank for your pump, and two shunts into a better space have quietly made a bigger job of what was simply a car standing still.
Every restart primes the lines and pulls more petrol past the filter then into your pump. So a wrongly fuelled diesel Nissan Qashqai on the zig-zags by St Clement Danes CofE Primary School is a nuisance, whereas the same motor started three more times to be courteous is a fuel system instead of a tank. A passer-by will advise you to move the car out of that gateway and fix it later. Please don't. Leave it there, let them moan, then phone us.
Leave it there overnight. Phone in the morning. Nothing about a diesel Audi A4 standing in the car park by The White Lion deteriorates as it sits, tank of petrol or not, and this job remains a simple one right up until the moment it gets taken home. The question we come with is about that trip there: a cold motor over a short distance is where petrol ignites least well, and whatever fails to burn can get past the piston rings into the oil.
Ringing from close to Margot Fonteyn? Three things help us. The filler — which side of the vehicle it's on. Room for a technician beside you, without the road being blocked. And whether anything has run since the fill-up. The spot itself hardly matters: on-street is where our engineers work most, and we would far rather have a cramped space than a motor someone has driven somewhere quicker. Then it is a drain for the Dacia Duster, a filter change where there's one worth changing, lines cleaned, clean fuel put round the entire system. By now the worst of that is in the fuel lines and not that tank.
Pump-side drains for petrol in a diesel
Forecourts are where the work usually begins, and where a large part of that ends. If you are still at the forecourt at Texaco, that is normally where the drain happens — we operate on petrol station forecourts all the time, with the owner's permission.
At a forecourt, the mistake is spotted with the engine never started, and no place else manages it. Everywhere else — a car park, a drive, a lay-by — the car was fired up and driven to get there, which means fuel was sucked from your tank, through your filter and into your high-pressure pump. That is not a catastrophe, and our engineers can still put it right where it is. It does mean your lines and the fuel filter need flushing as well as that tank, and that's decided by the few seconds between reading your receipt and going for the keys.
The attendants will usually help you roll it out from the petrol pump so the next motorist can get past. That's worth doing. Firing the car just for four vehicle lengths? Not a chance.
Areas we serve near Strand
Covent Garden, St Giles, Chinatown, Aldwych, Soho — each of them on the runs that take us across to Strand too, a residential suburb.
There are pages for nearly all locations around Greater London, and the ones named above are simply the nearest neighbours — so yours being absent from this list says nothing about if our engineers come. Phone to enquire instead of guessing — boundaries particularly, and wherever the satnav tends to get wrong.
That map shows the patch this page spans. Your vehicle does not need to travel to us. We work throughout all of that — roadside, forecourts, driveways, car parks.
Broken down at the roadside around Strand
Not everyone gets the opportunity to pull over anywhere safe. A routine call for us rather than an unusual one: realised after setting off, finished up along the verge on Long Acre or in a lay-by with the hazards on.
Fine where you are? Remain beside it. Not safe? Get out and away from it. It will usually oblige. A diesel running on petrol limps along perfectly willingly, and that is the problem: start it up to get to somewhere better and the blend goes further into your fuel system with every mile driven. However awkward the spot, it's no problem for us to come to it, and that is much better for the car than driving on.
Already run it? Petrol in a diesel over some miles
The M1 is the one which counts now, and it runs under 10 miles from Strand. A loss of power, a rough idle, smoke: those are the signs when they arrive, rather than a neat stop — and a misfuelled diesel will frequently take you onto it and some distance along before anything seems wrong at all.
Take the next junction that is sensible, stop there, and do not restart the car to reposition. Presume the worst of that on a long trip. Anything near the under a mile to the closest city, and the contamination has been through the filter, through your pump, through the injectors. Mention it when you ring. What our technicians bring differs.
Where's Strand?
Strand is a suburban area in the heart of London, situated on the north bank of the River Thames at an elevation of 34 metres. Strand sits adjacent to notable areas such as Covent Garden, St Giles, and Chinatown, and is within walking distance of Westminster. Strand is predominantly composed of flat dwellings, accommodating a population of approximately 8770 residents. Strand is characterised by its riverside location and proximity to central London, being just 0.4 miles from the city centre.
The visit in Strand, step by step
- We ask first, quote after. What was put in? How much? Has the engine run? Those replies change what the work actually is.
- Out goes the tainted fuel.
- Fuel lines are flushed through and your filter cleared, leaving nothing in the fuel system that caused any of this.
- Fresh diesel goes in, and then your system gets primed.
- When it is turned on, our technicians make sure it runs smoothly on new diesel.
Your car is then ready for you to drive away. All of it is done where your car is, so it never has to go to a garage, and when it has been noticed early, permanent damage is very unusual.
AdBlue in a diesel tank in Strand is a distinct problem
The fault is not the same, though the first rule is — do not fire it up — if what went in was AdBlue instead of petrol. Petrol weakens your diesel and removes the lubrication your fuel system relies on. Urea in water, AdBlue, and in a diesel tank that leads to rust and deposits.
Our engineers handle both, and AdBlue removal around Strand has its own page with the detail — including why it is usually the more significant of the two.
How much is a petrol-in-diesel fuel drain in Strand?
One price would not be honest here, since this isn't one job. These are the things that shift it:
- Whether the engine has been run or driven. This is the main one.
- How much of the wrong fuel was put in, measured against how much your tank can hold.
- Which got in: unleaded or AdBlue.
- Access: the vehicle's position, and whether working on it there is safe for a technician.
The vehicle, the quantity, whether it has run — give us those and the answer comes back clear rather than as a range. Not time-critical, with the vehicle at home and going nowhere? Then does this job.
Petrol in diesel: common questions around Strand
Fuel drains on a Strand petrol station forecourt
A fair part of this work takes place there, so yes. Our technicians work at Esso and the other forecourts around town routinely, with the site's agreement — tell us which one you're at when you call and we'll tell you whether we can work there.
Is there a sensible amount of petrol in a diesel?
Proportion settles it rather than litres — and more than either, whether your engine has run. Five litres in an almost empty tank is a distinct matter from five in a full one — but either way, the thing that decides how much work is needed is whether that blend has been pulled through your fuel system.
Already driven it with petrol in the diesel? Now what?
Stop safely. Off. Nothing after that. Driving is what shifts the issue from the tank into the pump and injectors — but it's fixable far more often than drivers fear, and the single most valuable thing you can do now isn't restart the car.
Is a fuel drain going to void my warranty?
It's not a modification, and so a drain then flush carried out correctly does not invalidate a manufacturer's warranty. An argument over a warranty is likelier to come from running a diesel on petrol — so leave it turned off.
Adding two-stroke oil, then driving home
No. It belongs to a separate issue from a bygone era, and petrol has weakened something no oil of that kind restores. Later on? Still petrol in the tank, and a pump that has to live with the stuff.
Do I need a main dealer for petrol in a diesel?
You don't need one. The vehicle is drained and flushed wherever it is, with no need to take it to a franchised dealer.
Standing next to it?
Don't turn your engine on again.
Already driven it? Then pull over somewhere sensible, turn off, then let it remain that way. Cold and stationary, a vehicle is in the best place available — and people fear this a lot more than the recovery rate warrants.
