Craiglockhart: Put Petrol in a Diesel Car?
Don't start the motor. While the petrol is still sitting in that tank and your engine has not yet run, a tank drain is nearly always all it needs — and that gets decided in the next few minutes, not by how much got in. Petrol in Diesel drains and flushes misfuelled vehicles where they stand, across Craiglockhart and the rest of City of Edinburgh, on the forecourt, by the roadside or on a drive. Our technicians shall explain what the following move will be. Ring us — it happens before everything else.
Petrol in a diesel: what to do first
- Don't fire it up. Turned on anyway? Then don't believe it. Diesel in a petrol vehicle normally cannot run, and so the person stops and the wear halts with them. Petrol in a diesel? It starts. It idles. It drives off happily, for several miles. Most people get that confused. It's not fine — the fuel system is grinding every mile you cover.
- Diesel ignites, and before it ignites it protects — your injection pump, those injectors. Petrol manages only the burning. So leave the ignition alone as well: switching it on is usually all it takes to prime the system, and priming pulls petrol from that tank into just those parts.
- Don't add diesel on top to weaken it. A diesel fuel system does not handle petrol by percentage the way that advice implies, and topping up clears nothing — it simply hands you a fuller tank of the same mixture. The octane makes no difference either: super unleaded is still petrol.
- Stay where you are if you safely can. A car that hasn't moved is the simplest one to deal with, and our team would sooner travel to an odd place than have it started. If you're stopped on the verge on Glenlockhart Valley, turn the hazards on then keep the vehicle there.
- Before you call, gather your location. Anything closest to you with a name on it, plus a postcode beginning EH14 1 — that is what settles whether the van turns up or circles.
- Three replies determine your whole call-out: the liquid you poured in, the ballpark measure involved, plus whether anything has been running since. Our number is 0333 366 0103.
Petrol in a diesel Renault Megane, left outside Slateford since breakfast? The wait has cost you nothing — fuel sitting in a tank is idle. It was the drive in that drew weakened diesel through your pump. Ring us before you drive the vehicle.
Twenty to nine by the local primary school, running late, and the receipt in your hand reads unleaded. Hazards on, engine off, ring us. Three miles in your BMW 3 Series feels like nothing, but a diesel pump delivers fuel on demand — while a frantic morning dash demands plenty.
Three replies decide much of the work: what was put in, approximately how much, and whether the engine has run since. We ask for those answers when we arrive at your car in the car park outside Village Inn. Then the contaminated blend comes out of the tank, the fuel lines are rinsed, and where your Audi A4 has a serviceable filter, it comes off. After new diesel is in and your system primed, we start it and make sure it runs correctly before you set off.
Sitting still, it gets no worse. Your pump is not turning, and so whatever occurred on the way to Thorny hedge in that diesel Peugeot 3008 is finished happening. Time is yours. Just don't take it home on the motor to find more of that.
Hire car? Company car? Call them before us. Some agreements want the firm to approve the work, and that is much faster dealt with up front than after that. Then ring us about the Mercedes A-Class, the diesel one, near Craiglockhart Vickers Wellington X3707 Memorial Cairn. Don't worry that you can't say how full the tank was — almost nobody can two days into a vehicle, and it is something our engineers establish on site. The reason for asking: harm from petrol in a diesel is a matter of ratio. A few litres in a nearly empty tank make a far stronger mix than in a full one, and petrol is built to resist the very thing a diesel needs of it, which is igniting when compressed. Stronger mix, more knocking, more smoke, flatter throttle.
Can petrol be taken from your diesel on a forecourt?
Pumps are where the work often starts, and where a good share of that ends. Still at BP? Then that is normally where it gets done. Station forecourts are normal for us, with the consent of the site.
At a forecourt, it is halted with the engine never started, and nowhere else manages that. Fuel sucked out of the tank and through your filter, right to your high-pressure pump, is what happens when the engine is fired up and the car is driven to where it is now: the car park, the driveway or the lay-by, everywhere other than the forecourt. So the flush covers the filter and your lines as well as the tank. That is still not a catastrophe, and we deal with it where your car stands. What decides it is whether the ignition was turned in the seconds after the receipt was read.
Attendants will normally pitch in pushing it away from the pump, which lets the next motorist get by. Welcome the offer. Four vehicle lengths isn't worth a start.
Service in Craiglockhart
Craiglockhart is a residential suburb, so our team head out to the town and to the areas by it on the same trips: Slateford, Colinton Mains, Morningside, Greenbank and Merchiston.
We still come. The names above are just the closest neighbours, and a page exists for most towns across City of Edinburgh, so an absence from the list isn't an absence from the coverage. Phone to enquire instead of assuming, especially when you're on a border or anywhere the satnav can't find.
The ground this page includes appears on the map. Every bit of it is territory our engineers work: a roadside, a forecourt, a private drive, a car park. You do not move the vehicle anywhere.
Craiglockhart: stuck where you pulled up
A chance to pull over somewhere safe doesn't fall to everyone. Hazards on in a lay-by somewhere, or stopped on the verge of Craiglockhart Road North as you noticed after setting off — our engineers take that call so often that it's the ordinary kind.
Fine there? Remain with it. Not okay? Step out and clear of it. Never restart it to get to a better location. It'll go — a diesel on petrol usually obliges — and each mile of obliging pulls the mixture deeper into your fuel system. However difficult the location, it is no problem for us to get to it, and that is much better for the car than driving on.
Already run it? Petrol in a diesel over a couple of miles
Your M8 is the one that counts now, and it sits under 3 miles from Craiglockhart. It will usually get you onto it, and some way along, before you spot a thing. Then it is some smoke, a lumpy idle and power ebbing away — not a tidy stop. Misfuelled diesels rarely give you one of those.
Take the next junction that's sensible, stop there, and never restart it to reposition. Long run? Anything approaching the under 3 miles to the closest city and you should presume the lot — filter, pump, injectors, all of it reached by the petrol. Say that on the call, because it changes what goes in the van.

Craiglockhart sits at an elevation of around 97 metres, with detached housing being the predominant type of accommodation in the area.

When our engineers arrive with you in Craiglockhart: what happens
- Our technicians find out what got in, how much, and whether the motor has run. The responses shape the work, which is why our technicians ask before pricing.
- The tainted fuel comes out of that tank.
- Fuel lines are flushed through and the fuel filter cleaned, leaving nothing in your system that started any of this.
- Bleeding your system follows, once new diesel is in.
- When it's started, we confirm it runs correctly on new diesel.
At that point it is ready to drive away. We do everything wherever the car has stopped, which means it never has to go to a garage, and when it has been caught early, it is very uncommon for there to be lasting damage.
AdBlue in a diesel tank around Craiglockhart is a different matter
The fault is not the same, though the first step is — never crank it — if what went in was AdBlue rather than petrol. Petrol dilutes the diesel and removes the protection the system depends on. AdBlue? Urea dissolved in water. Tip that in with your diesel and you get corrosion instead, plus build-up.
AdBlue removal around Craiglockhart has a page of its own with the details on it, including why it is usually the more serious of the two. Our engineers deal with both.
Craiglockhart prices for a petrol-in-diesel fuel drain
Our technicians can't put one figure on this page frankly, because this job is not one job. What changes it:
- Started? Driven? Either answer counts more than anything else on this list.
- How much of the wrong fuel went in, measured against how much that tank can hold.
- Which went in: unleaded or AdBlue.
- Whether our van can sensibly get to the vehicle and work on it, which depends on where your vehicle is.
Tell us the car, the amount and if it has run, and you'll get a firm answer rather than a range. For the car at home that's going nowhere and isn't time-critical, is fine too.
Petrol in diesel: frequent questions in Craiglockhart
I am on a forecourt in Craiglockhart. Can you drain it here?
Plenty of what our engineers do gets done nowhere else. So yes. Our technicians work at Asda and the other forecourts around town regularly, with the owner's permission — tell us which one you're at when you call and we will tell you whether our technicians can work there.
How much petrol in a diesel is too much?
Proportion settles it instead of litres — and more than either, whether your engine has run. Five litres in a nearly empty tank is a different situation from five in a full one — but either way, the thing that decides how much work is required is if that blend has been drawn through your fuel system.
Petrol in my diesel, and I have driven the vehicle
Turn off somewhere sensible, then keep it that way after you stop. It's recoverable a lot more frequently than people assume, even though driving is what shifts the problem from the tank into your pump and injectors — and the single most valuable thing you can do now is not restart it.
Fuel drains and manufacturer warranties
No. Carried out correctly, clearing and flushing is no alteration at all, and the warranty from your manufacturer is unaffected by it. An argument over a warranty is likelier to come from running a diesel on petrol — so leave it switched off.
Adding two-stroke oil, then driving home
What petrol has thinned is not put back by two-stroke oil, which is an old fix for a separate fault. So no. Petrol stays in that tank after that, whatever else goes in, and your pump gets no break from it.
Do I need a main dealer for petrol in a diesel?
Not at all. We drain and clean the car wherever it is, so there's no need to bring it to a dealership.
Still with the vehicle?
Leave the engine shut off.
Turn it off somewhere sensible then leave it off, if you have already driven it. This is recoverable from much more commonly than people fear, and a stationary, cold vehicle is the best place to be in.
