Petrol in Diesel

Put Petrol in a Diesel Car in Woodham? Don't Start It

If you have not fired up the engine as yet, do not. A drain and nothing else is nearly always what a car needs while the fuel is still in that tank and the engine has not yet run, which is why it's the coming few minutes that matter, not how much was put in. Petrol in Diesel comes to your car wherever it has stopped in Woodham or the rest of Surrey, on the forecourt, at the roadside or on a driveway, and drains and flushes it there. Contact us before all else happens, and you'll know what follows after that.

Your first five minutes: petrol in a diesel

  • Never start it — and never depend on it if it runs. This is the bit drivers have wrong about petrol in a diesel specifically. A petrol motor filled with diesel normally just can't run, so the driver stops and the damage stops with them. A diesel given petrol generally starts, idles and moves off just fine for several miles. It isn't all right. It's eating into the fuel system as you drive.
  • Two things, diesel: it burns, and on the way through it keeps that high-pressure fuel pump and injectors greased. Petrol only manages the one. That is why your ignition is left off as well — flick it on and you usually prime the system, and that is petrol leaving your tank for just those components.
  • That advice assumes a diesel fuel system accepts petrol by percentage. It does not. Tip diesel on top and nothing at all is removed; what you have is a larger tank of the same mix. And no, the octane makes no difference — super unleaded is just petrol.
  • A car that has never moved is the simplest one to sort out, and so remain where you are if you reasonably can. Pulled up on the verge on Woodham Park Road? Hazards on, then leave the vehicle there. A difficult spot suits us better than a started diesel.
  • Before you ring, have your whereabouts. Anything closest to you with a sign on it, plus a postcode that starts KT15 3 — that's what determines whether our van arrives or circles.
  • Call 0333 366 0103. Let us know what was put in, roughly how many litres, plus if the motor has fired. These three replies settle your whole job.

Call us before you move the car. Petrol into a diesel Volkswagen Golf this morning, and the vehicle outside West Byfleet ever since? Then the wait has taken nothing from you: fuel in a tank is inert, and any wear came on the drive in, when your pump was taking diesel that petrol had thinned.

The call our engineers want sounds like this: diesel Renault Megane, a few litres of unleaded, driven a couple of miles, now turned off outside Co-op Food. What we are really asking is how much fuel your pump has sucked — not how long ago it was.

Somebody will urge you to move the vehicle out of that gateway and sort it out later. Please don't. A misfuelled diesel Skoda Octavia on the zig-zags at New Haw Community Junior School is a hassle; the same motor started three more times to be polite is a fuel system and not a tank. Each restart primes your lines and draws more petrol past the fuel filter then into the pump. Leave it there, let everyone grumble, and give us a call.

Out there happy, back gutless. If that was the drive to Woodham Lodge Open Space, look at that tank. Diesel gets thinned by petrol, and thin fuel slips past the fine clearances supposed to build injection pressure — so every further mile your diesel Audi A4 covered, the less pressure it held onto. Somewhere safe, turn off, call us.

That deadness is the fuel failing to build pressure fully, not the motor giving up — and with no warning for it, vehicles in that position typically get driven again before somebody calls. Don't. A couple of streets is all it got: throttle gone dead, idle turned lumpy, and a diesel BMW 5 Series now waiting by Cornerstone Centre. Switch the vehicle off and ring us.

On the forecourt: removing petrol from the diesel

A fair share of the work is finished at a pump, as that's where it mostly starts. Still at Esso? Then that's typically where it takes place. Station forecourts are routine for us, with the agreement of the station.

At a garage, it is caught with the motor never run, and no place else manages it. The few seconds between seeing the till receipt and going for the key determine how much requires cleaning. Everywhere other than the forecourt — a car park, a private drive, a lay-by — the vehicle was switched on and moved to get there, so fuel was sucked from that tank, through your filter and into the high-pressure pump. That means the lines and the fuel filter need rinsing as well as that tank. It is not a calamity, and our technicians can still deal with it where the vehicle sits.

Push it out of the way if the staff offer, and they generally will. The next customer gets past the pump, and that is worth doing. Moving it four spaces doesn't warrant starting the motor.

Parts our team serve in Woodham

New Haw, West Byfleet, Rowhill, Sheerwater, Pyrford — every one of those on our trips that carry us over to Woodham as well, a village.

Our engineers still come. Those places above are only the nearest neighbours, and a page is there for the majority of locations around Surrey, and so an absence from the list isn't an absence from our coverage. Guessing is the mistake to avoid, particularly on a border or somewhere a satnav fails. Contact us to check.

The map outlines the area this page covers. We operate roadside, on forecourts, on driveways and in car parks over all of it, and the vehicle doesn't need to travel to us.

Broken down by the roadside around Woodham

The opportunity to stop somewhere sensible does not fall to everybody. A common call for us rather than an unusual one: noticed after setting off, landed by the verge beside Aprilwood Close or at a lay-by with your hazards going.

Whether you wait by your car or keep away from it depends on if being there looks safe. Do not restart it to get to a better spot. It will go — a diesel on petrol usually obliges — and each mile of obliging pulls the mix deeper into the system. A technician heading to an inconvenient location is no problem for us, and it is far better for the vehicle than pressing on.

Already run it? Petrol in a diesel after a few miles

This is where your M25 comes into it — under a mile from Woodham. Some distance along, and onto it in the first place: a misfuelled diesel will usually manage both before anything feels wrong. What you get then is rarely a neat stop. Power falls away, the idle gets lumpy, and there may be some smoke.

The next safe junction is the one to take. Turn off there, then leave the restarting alone. It alters what we bring, so say so when you phone: on a longer trip — anything close to the under 25 miles to the nearest city — assume the contamination has been through your filter, the pump and your injectors.

Woodham itself

Woodham is a village in Surrey, situated on the riverside at an elevation of 29 metres, with detached housing being the predominant type of accommodation. Woodham lies near the towns of New Haw, West Byfleet, and Rowhill, and is approximately 19.9 miles from London. Woodham has a population of around 2484 residents, who enjoy the scenic riverside setting. Woodham is also close to the city of Westminster, which is about 19.7 miles away.

Our call-out around Woodham, step by step

  • Our technicians check what was put in, how much, and if the motor has run. The responses alter the work, which is why our technicians ask before quoting.
  • Our engineers drain the tank of the contaminated mixture.
  • Fuel lines are rinsed through and the filter cleaned, leaving nothing in your system that caused any of this.
  • Clean diesel goes in, and then the fuel system gets primed.
  • We turn it on and check it runs correctly on new diesel.

That leaves your car ready to set off. There's no need for a garage at any stage, as the work is all done where the vehicle is, and when it's noticed early, lasting damage is very rare.

AdBlue in your diesel tank instead, around Woodham?

AdBlue instead of petrol? Then the opening rule is unchanged — the motor remains off — whereas the issue beneath it is a distinct one altogether. The lubrication a fuel system relies on is stripped away by petrol, which thins the diesel. AdBlue? Urea dissolved in water. Pour that in with your diesel and you get corrosion instead, plus deposits.

Both are ours. There is a separate Woodham page for AdBlue removal, with the detail 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 Woodham

Our technicians can't put one price on this page frankly, as the job isn't one job. What changes it:

  • Whether your motor has been run or driven. This is the key one.
  • The tank's capacity, set against how much of the wrong fuel got into it.
  • AdBlue or petrol, whichever was put in.
  • Where the vehicle is, and whether a technician can safely reach and work on it.

A straight answer rather than a range is what you get for telling us three things: your vehicle, the amount, and if it has run. If it's not time-critical — your car is at home and going nowhere — is fine too.

Things our engineers get about petrol in diesel in Woodham

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

Much of what our technicians do takes place nowhere else. So yes. Routinely, provided the site consents: JET, plus every other forecourt nearby. Say on the phone where exactly you have stopped. Whether we can work in that place is something we answer there and then.

A couple of litres of petrol in a diesel — too much?

It hinges on the ratio instead of the litres, and a lot more on whether the engine has run. What decides how much work is required is whether that mix has been pulled through the system — since though five litres in an almost empty tank is a separate matter from five in a full one, either way that's the query.

Already driven it with petrol in the diesel? What now?

Switch off somewhere sensible, then keep it that way after you stop. It's salvageable a lot more regularly than people assume, even though driving is what moves the issue from the tank into the pump and injectors — and the single most helpful thing you can do now is not restart it.

Will a fuel drain void my warranty?

A drain and flush carried out properly isn't a change and doesn't cancel a manufacturer's warranty. Running a diesel on petrol is the thing more likely to cause a dispute with one, which is another good reason to leave the vehicle turned off.

Can I just add two-stroke oil and drive home?

What petrol has weakened isn't restored by two-stroke oil, which is an old remedy for a different issue. So no. Your pump still has to live with it, since that tank still has petrol in it afterwards.

Does petrol in a diesel have to go to a main dealer?

You do not need one. Your car is drained and flushed wherever it is, with no need to take it to a main dealer.

Waiting next to it?

Keep it turned off.

If you have already driven it, pull over somewhere safe, turn it off then leave it off. This is recoverable from much more often than drivers assume, and a stationary, cold motor is the best position to be in.
