Put Petrol in a Diesel Car in Eyemouth?
If you have not fired up your engine yet, don't. A drain and nothing else is almost always what a motor needs while the fuel is still sitting in the tank and the motor has not yet turned over, which is why it is the next few minutes that matter, not how much was put in. Petrol in Diesel travels to the car wherever it has come to rest in Eyemouth or the remainder of Scottish Borders, on the forecourt, at the roadside or on a driveway, and drains and flushes it there. Our engineers shall tell you what the next part is. Phone — this goes before everything else.
Your next five steps: petrol in a diesel
- Give a petrol engine diesel and it will normally not run at all, so the motorist stops there and so does the wear. Feed a diesel petrol and the car starts, it ticks over, it pulls away — fine for a few miles. Motorists have that backwards, which is the bit they get wrong about petrol in a diesel specifically. So do not start it. And once started, do not rely on it: the fuel system is wearing down whenever you drive.
- Diesel burns, and before it ignites it lubricates — your injection pump, the injectors. Petrol manages only the burning. So leave the car's ignition be as well: turning it on is often all it takes to prime that system, and priming moves petrol from that tank into precisely those components.
- Topping up clears nothing. It leaves you a bigger tank of the same blend, because a diesel fuel system will not cope with petrol by percentage the way that guidance suggests — so do not add diesel on top to weaken it. Octane is irrelevant too: super unleaded is petrol.
- Sit tight if it is sensible to. Hazards on, ignition off, leave the car. Wherever you have stopped — the verge on Chapel Street, anywhere — an awkward spot for us trumps a started diesel, and nothing is simpler for us to sort out than a car that never moved.
- Before you dial, get your whereabouts. Anything next to you with a name on it, plus a postcode beginning TD14 5 — that's what determines whether the technician arrives or circles.
- Three details decide your whole call-out: the fuel you tipped in, the ballpark measure of it, plus if it has been turning since. Our line is 0333 366 0103.
Can petrol be drained from a diesel on the forecourt?
A fair share of the job is completed at the pump, because that's where it often begins. We work on station forecourts all the time, with the owner's permission, so if you're still at Scotish Fuels that's usually where the drain takes place.
Before your motor has fired — a garage is the one place this ends up spotted. Fuel drawn out of the tank and through the fuel filter, all the way to your high-pressure pump, is what occurs when the motor is started and the vehicle is driven to where it is now: the car park, the private drive or the lay-by, anywhere other than the forecourt. So the flush takes in the fuel filter and the lines along with the tank. That's still not a calamity, and our engineers sort it out where your car is. What settles it is whether the ignition was reached for in the seconds after your receipt was checked.
Push the vehicle out of the way if the staff suggest it, and they normally will. The next motorist gets by the pump, and that's worth doing. Shifting the car four bays doesn't warrant starting the motor.
Do our engineers reach your side of Eyemouth?
Eyemouth is a coastal town, and our team go out to the town and to the villages by it on the usual trips: Gunsgreen, Ayton Castle, Burnmouth, Ayton and St Abbs.
Not on that list? It means nothing. The names above are only the nearest few, and nearly all locations across Scottish Borders have a page of their own elsewhere on this site. On a boundary, or somewhere your satnav gets wrong? Contact us and enquire rather than assuming.
This map marks the area this page spans. Kerbside, forecourt, drive, car park: the lot is ground we serve, and none of that requires the car to move to us.
Eyemouth: stranded where you pulled up
Some people find no sensible spot to pull over whatsoever. Hazards flashing in a lay-by somewhere, or stopped on the verge of St Ella's Place as you noticed after setting off — we take that call regularly enough that it's the ordinary kind.
Sit beside your car if it is safe to be there, and out of the car when it is not. Never restart the engine to limp the car somewhere better — a diesel running on petrol will usually oblige, and every mile it obliges for is drawing the blend further into your fuel system. Our van driving to an awkward place is no bother for us, and it's a lot better for the car than driving on.
You set off at the end, once we have started the car and made sure it runs correctly on new diesel, with your system bled. Before that, in the car park outside The Contented Sole, the contaminated fuel comes out of that tank, your lines get cleaned and the fuel filter comes off where your Ford Focus has a replaceable one. It all begins with three questions when we get to the vehicle: what was put in, how much of it, and whether it has been fired up since.
Pull over somewhere safe, switch off and call us. Happy on the way out to Grassy Brae, sluggish on the way back? Then look at the tank. Petrol dilutes diesel; thinner fuel seeps past the close-fitting parts that build injection pressure; and the further your diesel Mercedes C-Class went, the less of that pressure it held.
Three things help when you ring from near Willie Spears Statue: which side the filler is on, whether our van can pull up beside without blocking the road, and if the motor has run since you filled up. On-street is the most common place our engineers work, and so the place itself is hardly ever the issue — we would far rather deal with a cramped parking bay than with a motor that has been driven to somewhere more convenient. We will drain the Audi A6, change the filter where there's a usable one, flush the fuel lines then put fresh fuel through the whole system, as by this point the worst of it is waiting in your lines rather than in your tank.
The smaller petrol nozzle goes into a current diesel filler neck with practically no resistance at all, which makes this mechanical instead of sloppy. New spots see most of it for that reason. So: fuelled up near Eyemouth War Memorial without thinking, in a diesel Volvo XC60 you have had for two days? Phone us where you are. Hire and courtesy cars often get driven further before anybody notices, and miles settles how much petrol ends up at the fuel injectors.
By now your tank is the least of it. Run a diesel and that blend goes into your filter, into the lines, into the pump, into the rail — and none of that leaves with that tank contents. A diesel Peugeot 2008 that got by Eyemouth Fishing Disaster Memorial needs its circuit cleared. Clearing is not the same thing.
A couple of miles on petrol in a diesel: what now?
Here is where the M8 comes in — under 50 miles from Eyemouth. A misfilled diesel will often take you onto it and some distance along before anything feels wrong, and the symptoms when they appear are generally a drop in power, a rough idle and smoke instead of a neat stop.
Never start it to reposition. Pull off at the next sensible junction and turn off. On a longer drive — anything near the under 50 miles to the closest city — take it the mixture has been through the filter, the pump and your injectors, and mention it when you phone. It affects what our technicians bring.
Where is Eyemouth?
Eyemouth is a coastal town in the Scottish Borders, situated on the northwestern coast of Scotland at a low elevation of around 8 metres. Eyemouth has a mix of housing types, but predominantly features terraced homes, reflecting its history of growth as a fishing and trading centre. Eyemouth is located near several notable places, including Gunsgreen, Ayton Castle, and Burnmouth, and is within commuting distance of Edinburgh, which is approximately 43 miles away. Eyemouth remains a small but significant community in the region, with a population of around 3695 people.
What follows when we get to you around Eyemouth
- We ask first, quote after. What went in? How much? Has the engine run? Those replies shape what the work really is.
- Our technicians clear the tank of all the contaminated mixture.
- Lines purged, filter cleared. Whatever remains after that isn't the thing that caused the trouble.
- Your system gets bled, on new diesel.
- It is fired up with clean diesel in it, and our engineers make sure that it is running smoothly.
That leaves it ready to drive away. Lasting damage is very unusual when it has been noticed quickly, and because all of it is done where your car is, it never needs to go to a garage.
AdBlue in your diesel tank instead, in Eyemouth?
Don't fire it up: that first step stands whether what got in was AdBlue or petrol. What changes is the fault itself. Petrol does two things to diesel: weakens it, and removes the lubrication the fuel system depends on. AdBlue is urea in water, and in a diesel tank it causes rust and build-up instead.
Both are ours. There is a separate Eyemouth page for AdBlue removal, with the details on it — including the reasons it often turns out to be the worse of the two.
How much is a petrol-in-diesel drain around Eyemouth?
What shifts the figure is laid out below, since this job isn't one job and we can't frankly put a single number on this page.
- This is the main one: whether your motor has been started, or driven.
- How much of the wrong fuel got in, measured against how much the tank takes.
- The type of liquid in the tank, petrol or AdBlue.
- Access: the vehicle's position, and whether working on it there's sensible for a van.
Tell us your car, the quantity and whether it has run, and you'll get a firm answer instead of a range. For the car at home that's going nowhere and is not urgent, works too.
Eyemouth motorists ask us these about petrol in diesel
Fuel drains on a Eyemouth petrol station forecourt
Much of what our technicians do takes place nowhere else. So yes. We visit Esso and the other forecourts around town all the time, with the station's permission — tell us which one you're at when you phone and we will tell you if we can work there.
How much petrol in a diesel is too much?
It rests on the proportion rather than the litres, and a lot more on whether your motor has run. What settles how much work is needed is if that mix has been pulled through the fuel system — because though five litres in a nearly empty tank is a separate situation from five in a full one, either way that is the question.
Petrol in my diesel, and I have driven the car
Pull in somewhere sensible, turn off, and leave it off. Driving is what shifts the issue from the tank into your pump and injectors — but it is recoverable a lot more often than drivers fear, and the single most helpful thing you can do now isn't restart it.
Will a fuel drain void my warranty?
A drain and flush carried out correctly is not an alteration and doesn't invalidate a manufacturer's warranty. Another good reason to leave it switched off: running a diesel on petrol is the thing more likely to cause a dispute with one.
Can I just add two-stroke oil and drive home?
No. Two-stroke oil is an old fix for a distinct fault and it doesn't restore what petrol has diluted. Later on? Still petrol in that tank, and a pump that has to put up with the stuff.
Does petrol in a diesel have to go to a main dealer?
Wherever the vehicle is, our engineers drain and flush it there, so a visit to the main dealer does not come into it.
You, and the car, still together?
Your engine stays off.
If you have already driven it, pull in somewhere sensible, switch it off then leave it off. This is recoverable from far more regularly than drivers expect, and a parked, cold vehicle is the best place to be in.
