Petrol in a Diesel Car in Addiebrownhill

Never turn on the motor. If the petrol is still in your tank and the engine has not yet turned over, a drain is nearly always all it needs — and that gets decided in the coming few minutes, not by how much got in. Petrol in Diesel drains and flushes misfuelled vehicles where they sit, throughout Addiebrownhill and the remainder of West Lothian, on the forecourt, at the roadside or on a driveway. Contact us before everything else happens, so you will hear what comes next.

Petrol in a diesel: what to try first

  • As you drive, the pump and the fuel injectors wear. That is why you do not fire it up, and why you do not believe it once it has started. The thing about petrol in a diesel in particular — the point most people get wrong — is that it pulls away fine for the first mile or two. Diesel in a petrol engine generally can't run at all, which stops the driver and stops the damage with them. This one lets you carry on.
  • Diesel ignites, and before it combusts it greases — that injection pump, those injectors. Petrol does only the burning. So leave your ignition alone also: flicking it on is usually all it takes to prime the system, and priming pulls petrol from that tank into precisely those components.
  • Do not add diesel on top to thin it. A diesel fuel system will not handle petrol by percentage the way that guidance presumes, and topping up takes out nothing — it only leaves you a fuller tank of the same mixture. The octane makes no difference either: super unleaded is still petrol.
  • Our team would much rather come to an awkward place than have it started — so if you safely can, stay still. Nothing is simpler to sort than a car that has never moved. On the verge on Meadowhead Crescent, that means hazards on then leave the car.
  • Before you ring, have your position. Anything next to you with a sign on it, plus a postcode beginning EH55 8 — that is what determines whether our van turns up or circles.
  • What went in, about how much, and also whether the car has fired — the three replies shape the whole call-out. Phone 0333 366 0103 then tell us.

Your high-pressure pump spent that morning drive running on a liquid that had lost a great deal of the protection it is built around. Diesel greases that pump, and the injectors with it, before any of your fuel ignites; petrol does the burning and none of the oiling. So imagine a diesel Volkswagen Golf, topped up at quarter past eight, taken in to work, and left sitting outside Addiewell until the penny drops close to eleven. Three hours of sitting have changed nothing about it. The few miles before that altered a good deal, which is why the thing our engineers ask you is about distance rather than time. Ring us. Keep the vehicle exactly where it stands.

Easy, these ones, and the reason is the mileage: a mile at light throttle pulls hardly any fuel. Petrol into a diesel Skoda Octavia somewhere around Addiebrownhill, a boot loaded with shopping, and you sat at Scotmid — call us. Getting out of the space isn't worth another start. Your tank gets cleared where it waits, your fuel lines flushed, fresh diesel in, and you head home.

Why we're firm about not driving on: your pump sits upstream of your injectors, so whatever a worn-out pump loses moves on with the fuel. Leave the Mercedes C-Class near Addiewell Community Centre then phone us.

Strange places are where this occurs most, and the reason is mechanical rather than sloppy: the smaller petrol nozzle goes into a current diesel filler neck with almost no resistance at all. Topped up near Loganlea Miners Club & Addiewell Pitstop without thinking, in a diesel BMW 1 Series you have had for two days? Call us where you are. Hire and courtesy cars tend to get driven further before anyone realises, and distance is what decides how much petrol gets to the fuel injectors.

No warning exists for this, which is why cars in that position normally get driven once more before anyone phones. Don't be one of them. The throttle went dead and the idle turned ragged after a couple of streets, and the diesel Vauxhall Astra is now resting by Addiewell and Loganlea Memorial Garden. Sluggishness there means fuel that cannot build pressure fully rather than an engine giving up. Switch off. Call us.

Mobile fuel drain van at a diesel car in Addiebrownhill

On a forecourt: removing petrol from the diesel

Forecourts are where this work mostly kicks off, and where a big chunk of that finishes. The drain usually happens on the spot. Still on the forecourt at BP? Given the station's agreement, that is a place we work, and regularly.

Nowhere else but the forecourt can this be halted with your motor still cold. Anywhere else — a car park, a drive, a lay-by — the vehicle was started and moved to get there, which means fuel was sucked from your tank, through your filter then into the high-pressure pump. That's not a disaster, and our engineers can still deal with it where it stands. It does mean your lines and your filter need flushing as well as that tank, and that's decided by the few seconds between reading the till receipt and reaching for your key.

The staff will normally offer to roll the car out from the petrol pump so the next motorist can get by. That's worth doing. Firing the car over four vehicle lengths? No.

Coverage in Addiebrownhill

Those same rounds get us to Loganlea, Addiewell, Stoneyburn, Longford Crofts and West Mains Crofts besides Addiebrownhill, which is a village.

Not on the list? That means nothing. The places above are only the nearest few, and most places around West Lothian have a page of their own elsewhere on the site. Assuming is the thing to avoid, particularly on a border or somewhere the satnav fails. Phone and enquire.

That map shows the ground this page includes. Roadside, forecourt, drive, car park: every bit of it is territory our technicians serve, and none of that needs the vehicle to travel to us.

Addiebrownhill: stuck wherever you parked

Some drivers get no safe place to pull over whatsoever. A normal call for us and not an odd one: realised after setting off, landed by the verge of Meadowhead Terrace or at a lay-by with the hazard lights going.

Okay there? Remain with it. Not okay? Get out and clear of it. Never fire it up to reach a better location. It'll go — a diesel on petrol generally obliges — and each mile of obliging drags the blend deeper into your fuel system. However tricky the place, it is no trouble for us to come to it, and that's far better for the vehicle than pressing on.

Some miles on petrol in a diesel: now what?

under 3 miles from Addiebrownhill, the M8 is what counts here. A drop in power, a rough idle, some smoke: those are the signs when they come, instead of a neat stop — and a wrongly fuelled diesel will usually take you onto it and some way along before anything seems wrong at all.

Take the first junction that's safe, pull up there, and don't restart it to move it. On a longer drive — anything close to the under 25 miles to the nearest city — assume the mixture has been through the filter, the pump and the injectors, and mention it when you call. It affects what our engineers bring.

A bit about Addiebrownhill

Addiebrownhill is a village situated on the riverside in West Lothian, with a mix of semi-detached housing and a population of around 951 residents. Addiebrownhill sits at an elevation of 198 metres, near the communities of Loganlea, Addiewell, and Stoneyburn. Addiebrownhill is located approximately 16.9 miles from Dunfermline, the nearest city, and is part of the wider Scottish landscape. Addiebrownhill's rural setting provides a contrast to the urban areas found in other parts of the country.

What our technicians do when our engineers reach you around Addiebrownhill

  • The replies alter the work, which is why we ask before quoting: what got in, how much of it, and whether the engine has run.
  • Our engineers clear the tank of the polluted mixture.
  • We rinse the lines and clean the filter, so what's left in the system is not what started the trouble.
  • New diesel goes in, and then the fuel system gets bled.
  • It's started with new diesel in it, and we check that it's running properly.

That leaves your car ready to set off. We do all of this wherever your car has come to a stop, which means it never has to be taken to a workshop, and when it has been spotted soon, it is very uncommon for there to be long-term damage.

AdBlue in a diesel tank around Addiebrownhill is a distinct matter

The issue is not the same, though the opening instruction is — do not fire it up — if what got in was AdBlue instead of petrol. Petrol does two things to diesel: weakens it, and removes the protection the fuel system depends on. Rust and deposits are what a diesel tank ends up with instead, as AdBlue is urea in water.

We handle both, and AdBlue removal around Addiebrownhill has its own page with the details — including why it is usually the more significant of the two.

How much is a petrol-in-diesel fuel drain around Addiebrownhill?

Frankly, no single figure belongs on a page like this. This job varies. Here is what moves it:

  • Started? Driven? Either answer counts more than anything else on this list.
  • Wrong fuel in, against what that tank takes — that proportion.
  • Whether it was petrol or AdBlue.
  • Access: the vehicle's position, and whether working on it there's safe for a van.

The vehicle, the amount, whether it has run — give us those and the answer comes back firm rather than as a range. If it's not urgent — the car is at home and going nowhere — is fine too.

Petrol in diesel questions from Addiebrownhill drivers

Can you do a fuel drain at a petrol station in Addiebrownhill?

Yes, and it's where a large share of this work takes place. Routinely, provided the site agrees: Shell, plus every other forecourt nearby. Say on the phone where precisely you have stopped. Whether our engineers can work in that place is something our engineers answer on the spot.

Is there a safe quantity of petrol in a diesel?

It depends on the ratio instead of the litres, and much more on whether the engine has run. Five litres into an almost dry tank isn't five into a full one, no. But both land on the same question in the end: has that blend been pulled right through, or has it not?

I put petrol in my diesel and drove the vehicle. What next?

Somewhere sensible, then stop, then switch off and keep it off. Not restarting it is the single most valuable thing available to you now. Driving does shift the issue out of that tank and into the pump and injectors, yes, and it stays recoverable a lot more often than people fear.

Fuel drains and manufacturer warranties

A drain then flush carried out properly isn't a change and doesn't cancel a manufacturer's warranty. Another reason to leave it turned off: running a diesel on petrol is the thing more likely to cause a disagreement with one.

Two-stroke oil in the tank, and then home?

No. Two-stroke oil is an old workaround for a separate issue and it doesn't restore what petrol has weakened. Afterwards? Still petrol in your tank, and a pump that has to live with the stuff.

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

No. Our engineers drain and clean the car wherever it is, so there is no need to bring it to a franchised dealer.

Standing next to it?

Shut off is how it stays.

Driven it already? Then somewhere safe, stop, turn off, and no restarting it later on. A stationary, cold motor is the best position to be in, and this is recoverable from far more regularly than drivers fear.
