Put Petrol in a Diesel Car in Almondvale? Don't Start It
If you have not turned on the engine yet, don't. A fuel drain and nothing else is nearly always what a vehicle needs while the fuel is still inside your tank and the motor has not yet been started, which is why it's the coming few minutes that matter, not how much went in. Petrol in Diesel goes to the vehicle wherever it has stopped in Almondvale or the rest of West Lothian, on the forecourt, at the roadside or on a drive, and drains and flushes it there. Contact us before all else begins, and you'll hear what follows from there.
Petrol in a diesel: what to try first
- Don't start the vehicle. Fired up anyway? Then don't rely on it. Diesel in a petrol car generally won't run, and so the motorist stops and the wear halts with them. Petrol in a diesel? It starts. It idles. It drives off happily, for a couple of miles. People get that muddled. It isn't fine — that fuel system is grinding every mile you do.
- Leave your ignition off as well. Diesel does two roles: it burns, and before it burns it lubricates your high-pressure pump and its injectors. Petrol does the first but not the second. Switching the ignition on is often all it takes to prime the system, which pulls the petrol out of your tank then into precisely those parts.
- Do not put diesel on top to weaken it. A diesel fuel system doesn't tolerate petrol by percentage as that advice assumes, and topping up clears nothing — it merely hands you a larger tank of the same mix. The grade makes no difference either: super unleaded is simply petrol.
- Stay where you are if you sensibly can. A vehicle that has never moved is the easiest one to sort out, and we would much rather come to a difficult place than have it started. If you are pulled up on the verge on Almondvale Court, switch the hazards on then keep the vehicle there.
- Check where you are before calling. A postcode that starts EH54 6, and the name of whatever is nearest to you. Otherwise the technician circles rather than turning up.
- Dial 0333 366 0103. Anticipate three questions — what was put in, about how many litres, and whether the engine has been run. Your responses decide whatever happens next.
How far you travelled is what our engineers ask about, not how long your car has been standing — and here is why. Diesel does two tasks on its way through the engine: it combusts, and before burning it protects the injection pump and the injectors. Petrol does the first only. So a fast fill-up on the way in, the penny dropping close to eleven, and a diesel Renault Megane parked outside Livingston South since quarter past eight shows those couple of miles were done with your pump running on a fluid stripped of a lot of its protection. Call us and keep it precisely where it sits.
Tell us this much and our engineers can work with it: a diesel BMW 3 Series, a few litres of unleaded in it, two miles or so, switched off at Asda now. Time gone by is not the thing our engineers need. Fuel drawn by the pump is.
Each restart primes the lines and drags more petrol through your filter and into your pump. So a misfuelled diesel Peugeot 308 on the zig-zags by the local primary school is an inconvenience, whereas the same vehicle started three more times to be helpful is a fuel system rather than a tank. Somebody will tell you to shift it out of the gateway and deal with it later. Do not. Leave it, let people grumble, then phone us.
Diesel has to be thick enough to seal the close-fitting components it flows through, and petrol weakens it. That is the whole process, and it explains the normal Dedridge Strip call: a diesel Audi A4 that went out there without a murmur and came back down on power, rough at idle, maybe smoking a little. A diesel injection system works hydraulically as well as chemically — it needs the fuel to hold pressure, not merely to burn — so when the fuel thins, pressure that should build then stay built starts escaping past tolerances instead, and the engine gets a poorer, later, less even delivery than it was built about. None of that is the motor failing, which is the part worth hearing: it is the fuel no longer acting like diesel, and it stops when the fuel is corrected.
A few streets, then it stopped. Throttle soft, idle lumpy, and your diesel Volkswagen Touran is parked up near Marks & Spencer. Your engine isn't packing up — that sluggishness is fuel that will not build pressure. There is no light on the dash for it, so motors like yours normally get driven once more before somebody picks up the phone. Don't. Off, then call us.
On a forecourt: removing petrol from a diesel
A large portion of the job is finished at a forecourt, as that is where it usually kicks off. Our technicians work on petrol station forecourts all the time, with the station's permission, so if you're still at Asda that's normally where the drain gets done.
No place but a garage can the mistake be halted with your motor still unstarted. Fuel drawn out of that tank and through the filter, right to the high-pressure pump, is what happens when the engine is switched on and the vehicle is moved to where it is now: the car park, the drive or the lay-by, anywhere other than the forecourt. So the flush takes in your filter and the fuel lines together with that tank. That's still not a disaster, and we sort it out where the car is. What settles it is whether the ignition was reached for in the seconds after the receipt was checked.
Clear of the petrol pump, the next motorist can get past — so yes, let the attendants help you push the vehicle. Very much worth it. Shifting it four lengths does not merit firing it.
Will our technicians reach your corner of Almondvale?
Livingston, Dedridge, Adambrae, Howden, Ladywell — all of them on the rounds that take us over to Almondvale too, a residential suburb.
We do come. The places above are only the nearest neighbours, and a page exists for nearly all locations around West Lothian, so an absence from the list is not an absence from the coverage. Close to the boundary, or somewhere a satnav struggles with? Contact us to ask instead of presuming.
This map shows the ground the page spans. Every bit of it is territory our engineers cover: a roadside, a forecourt, a drive, a car park. You don't move your vehicle anywhere.
Kerbside breakdowns in Almondvale
Not everybody has a decent place to pull over. Hazards going at a lay-by somewhere, or stopped on the verge on Almondvale Road because you realised after setting off — our technicians take that call so often that it is the usual kind.
Stay by the motor when it is sensible to sit there, and out of it if it isn't. Every mile a diesel obliges you for on petrol pulls that blend further into the system — and oblige it frequently will, which is why your engine does not get restarted to limp somewhere better. Our van driving to an awkward place is no problem for us, and it is a lot better for the vehicle than pressing on.
Already run it? Petrol in a diesel after a couple of miles
under 3 miles from Almondvale, your M8 is what counts here. A drop in power, a rough idle, smoke: those are the symptoms when they come, instead of a neat stop — and a misfuelled diesel will often take you onto it and some distance along before anything seems wrong at all.
Take the first exit that's sensible, stop there, and never start it to reposition. Presume the worst of that on a long run. Anything near the under 15 miles to the closest city, and the petrol has been through the filter, through your pump, through your injectors. Mention it when you call. What our engineers bring alters.
Where's Almondvale?
Almondvale is a suburban area situated on the riverside in West Lothian, with a mix of terraced housing and local amenities. Almondvale sits at an elevation of 117 metres, near the towns of Livingston and Dedridge. Almondvale is located close to the larger town of Livingston, with nearby Adambrae and other local neighbourhoods. Almondvale is approximately 13 miles from Dunfermline and 332 miles from London.
The call-out in Almondvale, step by step
- Three things get established before any quote — your fuel that was put in, the quantity, and whether anything has been run since. Each answer changes the work.
- Out goes the tainted fuel.
- Fuel lines are cleaned through and the filter cleared, leaving nothing in your system that created any of this.
- Priming follows, once fresh diesel is in.
- It's run with new diesel in it, and we make sure that it is running properly.
The car is then ready for you to drive away. Permanent damage is very rare when it has been spotted early, and since all of this is done where the car is, it never needs to be taken to a garage.
AdBlue in a diesel tank around Almondvale is a different problem
AdBlue instead of petrol? Then the opening instruction is unchanged — your motor stays off — while this fault under it is a different one altogether. Petrol weakens your diesel and strips the protection your fuel system depends on. AdBlue? Urea dissolved in water. Tip that in with your diesel and you get corrosion instead, plus deposits.
AdBlue removal in Almondvale has a page of its own with the detail on it, including why it's usually the more serious of the two. We handle both.
Almondvale prices for a petrol-in-diesel fuel drain
Our technicians cannot put one price on this page honestly, since the job is not one job. What changes it:
- This is the big one: whether your motor has been run, or driven.
- The tank's capacity, set against how much of the wrong fuel went into it.
- Whether it was petrol or AdBlue.
- Where your car is, and whether our van can sensibly get to and work on it.
Tell us what the vehicle is, how much got in, and if your engine has run. A clear answer comes back, not a range. For the car at home that is going nowhere and is not urgent, is fine too.
Petrol in diesel: frequent questions in Almondvale
At a petrol station in Almondvale, can you do a fuel drain there?
Yes — forecourts are where a large share of this takes place. Routinely, provided the site agrees: Sainsbury's, plus every other forecourt nearby. Say on the phone where precisely you have stopped. Whether our technicians can work in that place is something our technicians answer there and then.
Is there a sensible amount of petrol in a diesel?
Whether the motor has run counts a lot more, though the ratio matters too, instead of the litres. What settles how much work is required is whether that mix has been sucked through the system — because although five litres in an almost empty tank is a distinct situation from five in a full one, either way that's the query.
I put petrol in my diesel and drove the vehicle. What now?
Somewhere safe, then stop, then switch off and leave it off. It is fixable much more often than motorists fear, even though driving is what takes the problem from your tank into the pump and injectors — and the single most helpful thing you can do now isn't restart it.
Will a fuel drain void my warranty?
No. Carried out correctly, draining and purging is no alteration at all, and the warranty from your manufacturer is untouched by it. Another reason to leave it turned off: running a diesel on petrol is the thing more likely to cause an argument with one.
Could I put some two-stroke in and just drive?
No. It belongs to a distinct problem from a different era, and petrol has diluted something no oil of that kind restores. Petrol stays in that tank afterwards, whatever else goes in, and the pump gets no respite from it.
Does petrol in a diesel have to go to a main dealer?
There is no need to bring it to a franchised dealer, since our engineers drain and clean your car wherever it is.
Still with the vehicle?
Keep it switched off.
Already driven it? Then pull over somewhere safe, turn off, then let the car stay that way. A stationary, cold vehicle is the best position to be in, and this is recoverable from far more often than people assume.
