Petrol in a Diesel Car in Fairmilehead
Never turn on your engine. If the petrol is still inside that tank and the engine has not been started, a fuel drain is almost always all it requires — and that is decided in the coming few minutes, not by how much was put in. Petrol in Diesel drains and cleans misfuelled cars where they are, across Fairmilehead and the rest of City of Edinburgh, on the forecourt, by the roadside or on a driveway. Contact us before anything else starts, and you will see what follows next.
The first five minutes: petrol in a diesel
- Give a petrol engine diesel and it will typically not run at all, and so the person stops there and so does the harm. Give a diesel petrol and the thing starts, it idles, it pulls away — fine for a couple of miles. Most people have that backwards, which is the bit they get wrong about petrol in a diesel especially. So never start the car. And if started, never believe it: that fuel system is wearing down whenever you drive.
- Leave your ignition alone as well. Diesel has two roles: it burns, and before it ignites it lubricates the injection pump and its injectors. Petrol handles the first and not the second. Turning the car's ignition on is usually enough to prime that system, which moves the petrol out of that tank then into precisely those components.
- Do not add diesel on top to water down it. A diesel fuel system won't tolerate petrol by percentage the way that guidance implies, and topping up takes out nothing — it just leaves you a fuller tank of the same mix. The type makes no difference either: super unleaded is simply petrol.
- Wait where you are if you safely can. A motor that has never shifted is the simplest one to sort, and we'd much rather drive to a tricky location than have it started. If you are pulled up on the verge on Frogston Road West, put those hazards on and keep the car there.
- The van showing up rather than circling hinges on two things: a postcode that starts EH10 7, and whatever is closest to you with a label on it. Have both ready before you phone.
- Call 0333 366 0103. Say what went in, about how much, and also if the engine has started. Those three facts determine the full call-out.
Don't take it home. The journey in has already forced a real volume of petrol-thinned diesel through the high-pressure pump of your Volkswagen Golf, and the drive back would more or less double it for no gain at all. Ring us from the platform if that is quicker. Our technicians do not need you standing over the car outside Slateford whilst we work, and our team would very much rather hear from you tonight than discover on Monday.
Your diesel Skoda Octavia will have seemed entirely usual on the way back from the local primary school. They always do, and that is the catch with petrol in a diesel instead of the other way round. Put diesel in a petrol motor and it mostly won't run, so the driver stops and the harm stops with them. Put petrol in a diesel and it starts, idles and drives off as though nothing has happened — all while your high-pressure pump keeps working without the lubrication the fuel is supposed to be providing. Nothing warns you, since from the driver's seat there's nothing to warn you about. Ring us with approximately how far you drove and how hard you drove it; the second one matters more than the first.
Off the forecourt, receipt read, a few hundred yards, left close to Fairmilehead Parish Church. For a diesel Ford Kuga whose engine has turned, that's about the best version there is. Call us, and let it stand with your ignition alone. Short assists, genuinely — but a start is a start and a drive is a drive, and the filter has had diluted fuel through it, and so has your pump. Which is why the lines get flushed and not just the tank drained.
Rattling, a ragged idle, white smoke, a throttle gone limp. That is a misfuelled diesel Peugeot 208 telling you what's wrong. Switch off where you have stopped, near Caiy Stane or anywhere else, and do not start the car to find a better spot.
What takes place next is the problem. The engine straight away pulls the petrol still sitting in your filter and the feed lines back round through your pump a second time, since draining a tank does nothing about fuel that has already left it. Drain it then put fresh diesel in, a person sure of themselves will tell you — and that advice is only half right, as do it to a diesel Citroen C3 parked up, St Fillan say, and the thing starts, which is what makes it sound plausible. Phone us instead. Our technicians flush the circuit and take your filter off where the car has a serviceable one, and that is the difference between the vehicle being put right and your car simply starting.
Forecourt drains for petrol in a diesel
Forecourts are where this job usually begins, and where a fair chunk of it closes. We work on petrol station forecourts regularly, with the station's consent, and so if you're still at Esso that's normally where the drain happens.
Before the motor has started — the forecourt is the single spot this is stopped. Fuel sucked out of the tank and through your filter, all the way to the high-pressure pump, is what occurs when the engine is fired up and your car is driven to where it is now: the car park, the private drive or the lay-by, everywhere other than the forecourt. So the flush takes in your filter and the fuel lines along with your tank. That's still not a calamity, and we put it right where the car sits. What settles it is whether the key was turned in the seconds after the receipt was read.
The attendants will normally happily roll the vehicle clear of the petrol pump so the next customer can get by. It is worth doing. Four car lengths is not worth a restart.
Parts our team reach in Fairmilehead
Those same journeys carry us to Comiston, Lothianburn, Swanston, Oxgangs and Mortonhall along with Fairmilehead, which is a residential suburb.
Our technicians do come. Those names above are merely the nearest neighbours, and a page exists for most towns across City of Edinburgh, so an absence from the list is not an absence from the coverage. Assuming is the mistake to skip, particularly on the boundary or somewhere the satnav goes wrong. Contact us to check.
Check this map for the ground shown here. Your car does not need to come to us. We operate across all of that — roadside, forecourts, driveways, car parks.
Stranded on the kerbside in Fairmilehead
A chance to stop anywhere sensible doesn't fall to everybody. If you realised after setting off and finished up on the verge of B701, or in a lay-by somewhere with the hazard lights flashing, that is a routine call for us and not an odd one.
Safe where you are? Stay by it. Not safe? Get out and clear of it. Do not start it up to get to a nicer place. It'll go — a diesel on petrol generally obliges — and each mile of obliging drags that mix deeper into the fuel system. We will send the van to a tricky place without any fuss, and for the vehicle that is far better than carrying on.
A few miles on petrol in a diesel: what now?
This is where the M8 comes in, under 5 miles out of Fairmilehead. It will frequently take you onto it, and some way along, before you feel a thing. Then it's smoke, an uneven idle and power falling away — not a tidy stop. Misfuelled diesels rarely give you one of those.
Take the first exit that is sensible, pull up there, and never start it to reposition. Suppose the worst of it on a long run. Anything close to the under 5 miles to the closest city, and the mixture has been through the fuel filter, through the pump, through the fuel injectors. Mention it when you phone. What we bring changes.

Fairmilehead sits at an elevation of 179 metres, with detached housing being the predominant type of accommodation in the area. Fairmilehead is located close to several nearby places, including Comiston, Lothianburn, and Swanston, and is approximately 3.6 miles from Edinburgh city centre.
What our technicians do when we get to you in Fairmilehead
- Three things get established before any price — your fuel that got in, the amount, and whether anything has been run since. Each answer shapes the work.
- Our technicians drain your tank of all the polluted mixture.
- Lines rinsed, filter cleaned. Whatever remains later is not the thing that caused the trouble.
- The fuel system gets bled, on new diesel.
- It's fired up with fresh diesel in it, and our engineers make sure that it is running correctly.
Then it's ready to set off. All of it is done where the car is, so it never needs to be taken to a garage, and when it has been caught soon, permanent damage is very unusual.
AdBlue in the diesel tank instead, in Fairmilehead?
The fault isn't the same, though the first rule is — never start it — if what went in was AdBlue instead of petrol. Diluted diesel, and no protection left for the system that relies on it. That's petrol. Urea in water, AdBlue, and in a diesel tank that causes rust and residue.
AdBlue removal around Fairmilehead has a page of its own with the details on it, including why it's frequently the more serious of the two. Our technicians deal with both.
Fairmilehead prices for a petrol-in-diesel drain
Our engineers can't put one number on this page honestly, as this job is not one job. What changes it:
- This is the main one: whether your engine has been started, or driven.
- Wrong fuel in, against what your tank holds — that ratio.
- Which went in: unleaded or AdBlue.
- Where your car is, and whether a van can sensibly get to and work on it.
The vehicle, the quantity, whether it has run — give us those and the answer comes back clear instead of as a range. For the vehicle at home that's going nowhere and isn't time-critical, is fine too.
Questions our technicians get about petrol in diesel around Fairmilehead
At a petrol station around Fairmilehead, can you do a fuel drain there?
Much of what our technicians do takes place nowhere else. So yes. We work at Shell and the other forecourts nearby routinely, with the station's permission — tell us which one you're at when you call and we'll tell you if our engineers can work there.
How much petrol is too much for a diesel?
Whether your engine has run counts much more, though the proportion matters too, rather than the litres. Five litres in a nearly empty tank is a separate situation from five in a full one — but either way, the thing that settles how much work is needed is whether that blend has been sucked through your fuel system.
Already driven it with petrol in your diesel? What now?
Stop safely. Off. Nothing after that. Not restarting it is the single most valuable thing available to you now. Driving does move the trouble out of the tank then into the pump and injectors, yes, and it remains recoverable much more often than motorists assume.
Is a fuel drain going to void my warranty?
A drain and flush carried out properly isn't an alteration and doesn't cancel a manufacturer's warranty. A dispute over a warranty is likelier to come from running a diesel on petrol — so leave it switched off.
Could I put some two-stroke in and just drive?
Two-stroke oil solves a separate problem, and an old one at that. Nothing it does puts back what petrol weakened. No. After that? Still petrol in that tank, and a pump that has to cope with the stuff.
Does petrol in a diesel have to go to a main dealer?
Not at all. We drain and clean the car wherever it is, so there's no need to take it to a main dealer.
Standing next to it?
Turned off is the way the car stays.
Turn it off somewhere sensible then leave it off, if you have already driven it. Cold, parked, going nowhere: that is the best place to be in. Motorists fear this a lot more than they need to.
