Petrol in a Diesel Car in Merchiston
Never fire up your engine. While the fuel is still inside that tank and the motor has not turned over, a fuel drain is almost always all it takes — and that is determined in the next few minutes, not by how much went in. Petrol in Diesel drains and flushes misfuelled cars where they stand, all over Merchiston and the rest of City of Edinburgh, on the forecourt, at the roadside or on a private drive. One call to us is enough: we can show you what follows from here. Do it straight away.
What next? Petrol in a diesel, step by step
- Feed a petrol motor diesel and it will typically fail to run at all, and so the motorist stops there and so does the wear. Give a diesel petrol and the engine starts, it idles, it drives off — fine for a few miles. People have that backwards, which is the part they get wrong about petrol in a diesel especially. So never fire it up. And if started, don't depend on it: your fuel system is wearing while you drive.
- Switching the ignition on frequently primes the system, and priming is what moves petrol out of that tank then into your pump and injectors. Those are the parts diesel keeps greased on its way through, before it burns. Petrol does the burning and none of the oiling. Leave the car's ignition be.
- Don't dilute it. Diesel put on top removes nothing, and so all you have is more of what was already there, since percentage isn't how a diesel fuel system handles petrol. Super unleaded? Still petrol. The octane makes no difference.
- A vehicle that hasn't moved is the simplest one to handle, and so stay where you are if you reasonably can. Pulled up on the verge on Mid Gillsland Road? Hazards on, and keep the car there. A difficult location suits us better than a started diesel.
- Before you phone, get your position. Anything next to you with a label on it, plus a postcode starting EH10 5 — that's what decides whether our van shows up or circles.
- Ring 0333 366 0103. Tell us what went in, about how many litres, plus if the motor has started. These three answers determine the entire job.
The trip in is what sucked diluted diesel through the pump. Standing still has pushed nothing. Petrol in a diesel Volkswagen Golf, sitting at Slateford all day, sits harmless in your tank while it waits. Call us first — before the keys turn.
Each start primes the fuel system and sucks more of the mix out of that tank and on to your pump — which is why a car shunted twice into a roomier space has quietly become a harder job than one left precisely where it stopped. So if our engineers can't work beside your diesel Renault Megane, our technicians move the car without starting it. None of that is fuss about a few seconds of running. Car parks like the one at Waitrose our engineers visit all the time, and your fuel is hardly ever the complicated part: the bay is. Motors either side, a trolley shelter behind, occasionally a height limit at the way in determining if a van can reach you at all. Tell us how boxed in you are, and which way your car faces.
What we'll ask is whether the trip there was short and cold, since that is where petrol is least likely to burn correctly — and what doesn't burn can slip past the piston rings and into the engine oil. Right up to the moment somebody drives it home, a diesel Peugeot 308 parked in the parking area by The Caley Sample Room holding a tank of petrol in it is a simple job. Nothing deteriorates while it waits, so park the vehicle there overnight and phone next morning.
Do not drive it home to buy yourself time. You already have it: nothing gets worse whilst the vehicle waits, because a diesel Mercedes C-Class left outside Merchiston Garden is doing none of what it did on the way there. Your pump has stopped turning.
No dashboard light exists for this, which is why cars in that position generally get driven once more before anybody rings. Don't be one of them. The throttle went soft and your idle turned uneven after a few streets, and your diesel BMW X1 is now resting by Polwarth Church. Softness there means fuel that cannot build pressure correctly rather than a motor failing. Turn off. Call us.
At a forecourt: removing petrol from the diesel
Pumps are where the job mostly starts, and where a fair chunk of it finishes. The drain typically happens on the spot. Still on the forecourt at BP? Given the owner's permission, that is a spot our engineers work, and often.
The forecourt is the single place this can be stopped before your motor has run. The few seconds between reading the till receipt and going for the key determine how much requires flushing. Everywhere other than the forecourt — a car park, a driveway, a lay-by — the car was started and moved to get there, so fuel was pulled from that tank, through the fuel filter and into the high-pressure pump. That means your lines and your filter require rinsing as well as that tank. It is not a calamity, and our technicians can still deal with it where the car stands.
Wheel it out of the way if the staff volunteer, and they normally will. The next customer gets through the petrol pump, and that is worth doing. Shifting it four lengths does not justify starting the motor.
Do we cover your part of Merchiston?
Being a residential suburb, Merchiston gets a routine call, whilst its neighbours nearby go with it on that same round: North Merchiston and Churchhill, Dalry and Gorgie, Morningside.
There are dedicated pages for most towns in City of Edinburgh, and the ones listed above are simply the nearest neighbours — so yours being absent from that list says nothing whatsoever about whether our technicians come. Contact us to ask rather than guessing, above all when you are on a boundary or somewhere your phone misreads.
The patch this page spans appears on the map. We operate by the road, at forecourts, on driveways and at car parks throughout all of it, and the vehicle never needs to move to us.
Roadside call-outs across Merchiston
Not everybody has a chance to pull over anywhere safe. If you worked it out after setting off and finished up along the verge of Gillsland Road, or in a lay-by somewhere with your hazards flashing, that is a normal call for us instead of an unusual one.
Okay there? Stay with it. Not fine? Climb out and clear of it. Every mile a diesel obliges you for on petrol draws the mix further into the system — and oblige it often will, which is why your engine doesn't get restarted to limp somewhere safer. Carrying on causes the car far more harm than a technician coming out to a difficult location, and that is no problem for us.
Already run it? Petrol in a diesel over some miles
The M8 is the one that matters here, and runs under 5 miles from Merchiston. A misfuelled diesel will usually get you onto it and some distance along before anything seems wrong, and the symptoms when they appear are typically lost power, a rough idle and some smoke instead of a neat stop.
Don't start it to move it. Pull off at the first sensible exit then turn off. Long run? Anything close to the under 3 miles to the closest city and you should suppose the lot — filter, pump, injectors, all of it got to by the petrol. Say that on the call, since it alters what goes in the van.
Where is Merchiston?
Merchiston is a suburban area in the City of Edinburgh, situated approximately 1.9 miles from Edinburgh city centre. Merchiston occupies a coastal setting with an elevation of around 86 metres, and is characterised by predominantly flat-type housing. Merchiston is close to nearby places such as North Merchiston, Churchhill, and Dalry, and is home to a population of around 9601 residents.
What happens when our engineers reach you around Merchiston
- Three things get asked before any quote — the fuel that was put in, the quantity, and whether anything has been run since. Each answer alters the work.
- Away comes the contaminated fuel.
- What is left in the system should not be what started the problem, and so the lines get cleaned and the fuel filter cleared.
- Our technicians put fresh diesel in and bleed the system.
- It is started with new diesel in it, and our engineers make sure that it is running properly.
That has it ready to pull away. Permanent damage is very rare when it has been spotted early, and because all of this is done where the car is, it never has to go to a workshop.
Merchiston AdBlue removal is a different job
AdBlue instead of petrol? Then the first instruction is unchanged — the motor stays off — while the issue beneath it is a separate one altogether. Diluted diesel, and no protection left for your fuel system that depends on it. That's petrol. Urea in water, AdBlue, and in a diesel tank that brings corrosion and deposits.
AdBlue removal around Merchiston has a page of its own with the detail on it, including why it is often the more significant of the two. Our technicians handle both.
Paying for a petrol-in-diesel drain in Merchiston
We cannot put one number on this page frankly, as this job is not one job. What moves it:
- This is the key one: whether your engine has been run, or driven.
- Wrong fuel in, against what that tank takes — that ratio.
- 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 technician.
Tell us the vehicle, the amount and whether it has run, and you'll get a firm answer rather than a range. If it is not time-critical — the car is at home and going nowhere — is fine too.
Questions we get about petrol in diesel around Merchiston
I'm on a forecourt in Merchiston. Can you drain the vehicle here?
Yes — forecourts are where a fair share of this happens. Tell us which one you are at when you phone and we'll tell you whether our technicians can work there. With the station's consent our technicians work at JET and the other forecourts nearby regularly.
Is there a sensible amount of petrol in a diesel?
Litres are not the measure. Proportion is, and far more than either, it counts whether anything has been run. Five litres into a nearly dry tank isn't five into a full one, no. But both land on the same question in the end: has that mix been pulled right through, or has it not?
Already driven it with petrol in the diesel? What then?
Stop safely. Off. Nothing after that. Driving is what takes the problem from your tank into the pump and injectors — but it's recoverable a lot more often than people fear, and the single most valuable thing you can do now isn't restart the car.
Will a fuel drain void my warranty?
It's not an alteration, and so a drain then flush carried out correctly does not 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.
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 diluted. No. Your pump still has to cope with it, as that tank still has petrol in it later on.
Does petrol in a diesel have to go to a main dealer?
No. Our technicians drain and flush your car wherever it is, so there's no need to bring it to a dealership.
Still with the car?
Shut off is the way the car stays.
If you have already driven it, pull in somewhere safe, turn it off then leave it off. Cold, still, going nowhere: that is the best position to be in. Motorists fear this much more than they need to.
