Petrol in Diesel

Put Petrol in a Diesel Car in Kensal Rise?

If you have not turned on the engine yet, don't. A fuel drain and nothing else is almost always what a vehicle needs while the fuel is still sitting in your tank and the engine has not run, which is why it is the following few minutes that count, not how much went in. Petrol in Diesel goes to the vehicle wherever it has stopped in Kensal Rise or the remainder of Greater London, on the forecourt, by the roadside or on a driveway, and drains and cleans it there. One call to us will be plenty: we will tell you what happens after this. Make it right away.

Petrol in a diesel: what to try next

  • As you drive, your pump and your injectors wear. This is why you never crank it, and why you never depend on it once it has started. The trick about petrol in a diesel in particular — the bit motorists get wrong — is that it drives away fine for the first mile or two. Diesel in a petrol motor typically will not run at all, which stops the person and stops the wear with them. This one lets you carry on.
  • Diesel burns, and before it burns it protects — that high-pressure fuel pump, the injectors. Petrol does only the burning. So leave the car's ignition be too: switching it on is frequently all it takes to prime that system, and priming carries petrol from the tank into precisely those components.
  • Topping up clears nothing. It gives you a bigger tank of the same blend, because a diesel fuel system won't tolerate petrol by percentage in the way that advice presumes — so do not add diesel on top to thin it. Type is immaterial too: super unleaded is petrol.
  • Our team would rather come to an odd location than have it started — so if you reasonably can, stay put. Nothing is simpler to sort out than a motor that has not moved. On the verge on Chevening Road, that means hazards on then leave the car.
  • Before you dial, work out your whereabouts. Anything closest to you with a sign on it, plus a postcode that starts NW6 6 — that's what determines whether the technician turns up or circles.
  • Dial 0333 366 0103. Tell us what got in, about how many litres, plus if the engine has run. These three details settle the entire job.

Draining petrol from the diesel at the forecourt

Forecourts are where this work often starts, and where a good share of it finishes. If you're still on the forecourt at Shell, that's usually where the drain happens — we work on station forecourts routinely, with the station's consent.

A filling station is the only spot the mistake can be stopped before the engine has fired. Anywhere else — a car park, a drive, a lay-by — the car was switched on and driven to get there, which means fuel was drawn from your tank, through your filter then into your high-pressure pump. That's not a calamity, and we can still deal with it where it is. It does mean the lines and the fuel filter need rinsing as well as the tank, and that's determined by the few seconds between seeing the receipt and going for your key.

The attendants will generally offer to move the car away from the pump so the next driver can get by. That's worth doing. Moving the car four bays doesn't justify firing the motor.

Mobile fuel drain van at a diesel car in Kensal Rise

The enquiry we want goes like this: diesel Volkswagen Tiguan, a few litres of unleaded, done a couple of miles, now shut off at Planet Organic. What we are actually asking is how much fuel your pump has drawn — not how long ago it was.

Straightforward job, this one — until someone takes it home. A diesel Peugeot 3008 left by The Chamberlayne with petrol in the tank loses nothing by sitting there overnight, so leave the vehicle then phone once it is light. Expect a question about that drive there, though. Short and cold is exactly where petrol struggles to burn, and what won't burn can work past the rings and into the oil.

Never drive it home to buy yourself time. You already have it: nothing gets worse whilst the vehicle waits, as a diesel Mercedes E-Class left outside Queens Park Tennis Courts is doing none of what it did on the way there. The pump has stopped turning.

Pulled off the forecourt, read your receipt, and left the diesel Audi A3 up near Pet's corner a few hundred yards later? That's about as well as this goes once the motor has turned. Ring us and leave it off. The short hop truly assists, but it was still a start and a drive, and so thinned fuel has reached the filter and your pump — which is why our engineers flush the lines instead of only clearing your tank.

The narrower petrol nozzle slides into a modern diesel filler neck with almost no resistance at all, which makes this mechanical not sloppy. New spots see most of that for that reason. So: topped up by Imam Khoei Islamic Centre without thinking, in a diesel BMW 1 Series you have had for two days? Phone us where you are. Hire and courtesy cars usually get driven further before anybody notices, and distance settles how much petrol gets to the injectors.

Places our vans reach around Kensal Rise

Brondesbury Park, Queens Park, Kilburn, Kensal Green, Willesden Green — all of them on our trips that bring us out to Kensal Rise too, a residential suburb.

There are pages for the majority of places across Greater London, and the ones listed above are just the immediate neighbours — so yours being missing from this list means nothing about whether our engineers come. Call us to ask rather than assuming — borders especially, and anywhere the satnav might get wrong.

The area this page includes appears on our map. Your vehicle doesn't need to move to us. Our technicians work across every bit of it — kerbside, forecourts, driveways, car parks.

Stuck on the kerb somewhere in Kensal Rise?

Not everyone has the chance to pull over anywhere sensible. If you noticed after setting off and landed along the verge beside Milman Road, or at a lay-by somewhere with your hazards on, that is a normal call for us rather than an odd one.

Sit by the vehicle when it's sensible to wait there, but out of the vehicle if it's not. It will often oblige. A diesel running on petrol limps along quite willingly, and that is the catch: fire it up to get to somewhere better and that blend goes further into the system with every mile covered. We'll send the van to a tricky place without any fuss, and for your car that is far better than pressing on.

Some miles on petrol in a diesel: what next?

This is where your M1 comes into it — under 3 miles from Kensal Rise. A misfilled diesel will often take you onto it and some distance along before anything seems wrong, while the symptoms when they arrive are usually lost power, a rough idle and smoke rather than a clean stop.

Do not restart it to reposition. Get off at the first sensible junction then turn off. On a longer drive — anything close to the under 5 miles to the closest city — take it the mixture has been through your filter, your pump and your injectors, and mention it when you ring. It alters what our engineers bring.

A little about Kensal Rise

Kensal Rise is a suburban area in northwest London, situated approximately 4.2 miles from the city centre. Kensal Rise has a relatively low elevation of 51 metres and is surrounded by nearby places such as Brondesbury Park, Queens Park, and Kilburn. Kensal Rise is predominantly composed of flat housing, which accommodates its population of around 12,618 residents. Kensal Rise is close to Westminster, which is about 4.5 miles away.

The visit around Kensal Rise, step by step

  • Our engineers find out what got in, how much, and whether the motor has run. The responses change the work, which is why we ask before giving a price.
  • The tank is drained of it.
  • Lines rinsed, filter cleaned. Whatever remains after that isn't the thing that started the trouble.
  • We pour new diesel in and prime your system.
  • Our engineers start it and make sure it runs properly on clean diesel.

From that point, you're ready to set off. Our technicians do all of it wherever the car has ended up, which means it never has to go to a workshop, and if it has been caught soon, it's very unusual for there to be permanent damage.

AdBlue in a diesel tank around Kensal Rise is a separate problem

If what went in was AdBlue rather than petrol, the first step is the same — don't crank it — but this fault isn't. Petrol weakens the diesel and takes away the lubrication the system depends on. Corrosion and deposits are what a diesel tank ends up with instead, as AdBlue is urea dissolved in water.

Usually the more serious of the two, AdBlue — and the full story sits on its own Kensal Rise page. Both are ours to handle.

Paying for a petrol-in-diesel drain around Kensal Rise

What shifts the figure is set out below, since this job isn't one job and our engineers cannot truthfully put a single figure on this page.

  • Has it been run or driven? Nothing else counts for as much.
  • How much of the wrong fuel got in, against how much that tank takes.
  • The kind of fluid in the tank, unleaded or AdBlue.
  • Where is it? And can our van reach it and work there safely?

A firm answer rather than a range is what you get for telling us three things: the car, the quantity, and if it has run. For your car at home that is going nowhere and isn't pressing, is fine too.

Kensal Rise motorists ask us these about petrol in diesel

At a petrol station around Kensal Rise, can you do a fuel drain there?

Yes, and it's where a large portion of this work happens. Permission from the site is the condition. Given that, a forecourt like Sainsbury's is somewhere we are often enough, along with the rest of them locally — so name yours on the call and you'll hear whether working there's possible.

How much petrol is too much for a diesel?

Whether your engine has run counts a lot more, though the ratio counts too, instead of the litres. A nearly empty tank with five litres in it, against a full one with the same five: distinct situations, of course. Either way, the work needed comes down to one thing, which is whether your fuel system has had that blend drawn through it.

I drove the vehicle after putting petrol in my diesel. What now?

Somewhere safe, then stop, then switch off and keep it off. Driving is what shifts the issue from that tank into the pump and injectors — but it is salvageable far more commonly than motorists assume, and the single most valuable thing you can do now isn't restart the vehicle.

Will a fuel drain void my warranty?

No. Carried out properly, emptying and rinsing is no modification at all, and the warranty from your manufacturer is unaffected by it. Another reason to leave it turned off: running a diesel on petrol is the thing likelier to cause an argument with one.

Adding two-stroke oil, then driving home

No. Two-stroke oil is an old fix for a different fault and it doesn't put back what petrol has diluted. Your pump still has to cope with it, as your tank still has petrol in it later.

A main dealer for petrol in a diesel — needed?

No. Our engineers drain and clean the car wherever it is, so there's no need to take it to a main dealer.

Still with the vehicle?

The engine remains off.

Already driven it? Then stop somewhere safe, turn off, and let the vehicle remain that way. Cold, still, going nowhere: that's the best position to be in. Motorists fear this a lot more than they need to.

Throughout Greater London and around Kensal Rise: on-site fuel draining, at home or on the forecourt or at the kerbside.
