Put Petrol in a Diesel Car in Quarryhead?
If you have not turned on the motor yet, do not. A fuel drain and nothing more is almost always what a car needs while the petrol is still sitting in your tank and the engine has not yet run, which is why it is the coming few minutes that count, not how much got in. Petrol in Diesel goes to your car wherever it has come to rest in Quarryhead or the remainder of Midlothian, on the forecourt, at the roadside or on a drive, and drains and cleans it there. Call us before all else starts, so you'll see what happens after that.
What to try now about petrol in a diesel
- As you drive, the pump and the fuel injectors wear down. This is why you do not fire it up, and why you don't believe it once it has started. The trick about petrol in a diesel in particular — the point drivers get wrong — is that it drives away normally for the first mile or two. Diesel in a petrol motor usually can't run at all, which stops the person and stops the harm with them. This one lets you keep going.
- Two things, diesel: it combusts, and on the way through it keeps the injection pump and injectors lubricated. Petrol only does the one. Which is why the ignition is left off too — flick it on and you usually prime the system, and that is petrol exiting that tank for exactly those components.
- Do not add diesel on top to water down it. A diesel fuel system doesn't handle petrol by percentage in the way that advice assumes, and topping up gets rid of nothing — it simply leaves you a larger tank of the same blend. The type makes no difference either: super unleaded is simply petrol.
- We'd much rather travel to an awkward place than have it started — so if you reasonably can, stay put. Nothing is quicker to handle than a motor that has not moved. On the verge on Viewbank Road, that means hazards on and leave the car.
- Find out where you are before ringing. A postcode beginning EH19 2, and the name of whatever is closest to you. Otherwise the technician circles instead of showing up.
- Three details settle the entire job: the liquid you poured in, the approximate quantity involved, and if it has been turning since. Our number is 0333 366 0103.
Forecourt draining for petrol in a diesel
Much of the job begins at a pump, so a good chunk of that gets completed at one. Still at Tesco? Then that is normally where it gets done. Petrol station forecourts are normal for us, with the consent of the site.
No place except the forecourt can this be spotted with the motor still unrun. We can still deal with it where it sits, even away from the forecourt. In a car park, on a driveway or in a lay-by, your car has been switched on and driven there, and that pulled fuel through the filter then into your high-pressure pump, right from the tank. None of that is a catastrophe, although the flush then has to go past the tank to the fuel lines and the fuel filter, and the few seconds between checking your receipt and going for the keys are what settle that.
Roll the vehicle out of the way if the attendants volunteer, and they usually will. The next driver gets past the pump, and that's worth doing. Four car lengths isn't worth the risk.
Can our engineers serve your end of Quarryhead?
Quarryhead is a residential suburb, and our team head out to the town and to the villages around it on the same journeys: Eldindean, Broomieknowe, Lasswade, Waverley and Bonnyrigg.
There are dedicated pages for the majority of places in Midlothian, and the ones named above are just the nearest neighbours — so yours being absent from this list says nothing at all about if we come. Assuming is the thing to skip, above all on the border or anywhere a satnav struggles. Phone to check.
The area the page covers is on the map. Roadside, forecourt, private drive, car park: every bit of that is ground our technicians cover, and none of that needs the car to move to us.
Hazards on. Motor off. Call us. It is twenty to nine at the gates of the local primary school, you are late, and your receipt shows unleaded — and although three miles in the Nissan Qashqai sounds like nothing, fuel is supplied on demand, and a hurried drive needs plenty of it.
Straightforward job, this one — till somebody takes it home. A diesel Audi A4 sitting at The Anvil Inn with petrol in the tank loses nothing by sitting there overnight, and so leave the car and ring us once it's light. Expect a question about that trip there, though. Short and chilly is exactly where petrol battles to burn, and what will not burn can get past the rings and into the sump.
Pulled off the forecourt, read the till receipt, and parked your diesel BMW 1 Series up close to Bonnyrigg Parish Church a few hundred yards later? That's about as well as this goes once your engine has turned. Call us then leave the vehicle off. The short drive genuinely helps, but it was still a start and a drive, so weakened fuel has reached the fuel filter and the pump — which is why our technicians flush the lines rather than only draining that tank.
Hire car? Company car? Phone them before us. Some contracts want the firm to authorise the work, and that is much quicker dealt with up front than later on. Then ring us about the Ford Fiesta, the diesel one, by Michael McGahey Memorial. Do not worry that you can't say how full that tank was — nearly nobody can two days into a vehicle, and it is something we establish on the spot. 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 mixture 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.
Somebody sure of themselves will tell you to drain it and put clean diesel in. Only half right, that. Try it on a diesel Vauxhall Insignia by Madinah Masjid & Community Centre and your engine will start — which is precisely why it sounds like sense. Here's the trouble: there's petrol left in your filter and the feed lines, and the first thing the engine does is pull it back through your pump once more. Draining a tank achieves nothing about fuel that already left that tank. Call us. The circuit gets purged, the fuel filter comes off where there is one worth removing, and that is what separates a repaired motor from one that only starts.
Stuck by the kerb somewhere around Quarryhead?
Not everybody finds a suitable place to pull over. If you realised after setting off and finished up on the verge beside Eldindean Road, or at a lay-by somewhere with the hazards on, that is a common call for us and not a rare one.
Sit by the vehicle when it is wise to sit inside, but out of the car when it is not. Do not start up your engine to nurse the car somewhere better — a diesel running on petrol will often oblige, and every mile it obliges for is pulling the mixture further into the system. However tricky the location, it's no trouble for us to get to it, and that's far better for the car than pressing on.
Already run it? Petrol in a diesel over a couple of miles
Here is where the local M8 comes in, under 10 miles out of Quarryhead. A loss of power, a rough idle, some smoke: those are the signs when they arrive, instead of a neat stop — and a misfilled diesel will often get you onto it and some way along before anything feels wrong at all.
Don't restart it to reposition. Come off at the first sensible exit then turn off. Long drive? Anything near the under 10 miles to the closest city and you should assume the lot — filter, pump, injectors, all of it arrived at by the petrol. Say that on the phone, since it changes what goes in the van.
Where's Quarryhead?
Quarryhead is a suburban area situated on the riverside in Midlothian, with a mix of semi-detached housing and other residential properties. Quarryhead sits at an elevation of 102 metres, close to the nearby places of Eldindean, Broomieknowe, and Lasswade. Quarryhead is located approximately 6.1 miles from Edinburgh, making it a commuter-friendly location. Quarryhead has a population of around 4673 residents, who enjoy the area's scenic riverside setting.
What happens when we get to you in Quarryhead
- Three things get established before any quote — your fuel that got in, the amount, and whether anything has been run since. Each answer changes the work.
- We drain the tank of the contaminated mixture.
- What is remaining in the fuel system should not be what created the trouble, so the lines get flushed and your filter cleared.
- Priming follows, once fresh diesel is in.
- Once it's fired up, we check it runs properly on clean diesel.
From that point, you are ready to pull away. There's no need for a workshop at any stage, because the work is all done where the car is, and when it's caught quickly, permanent damage is very unusual.
Quarryhead AdBlue removal is a separate job
The fault is not the same, though the first rule is — do not start it — if what got in was AdBlue instead of petrol. Petrol does two things to diesel: weakens it, and takes away the protection the fuel system relies on. Urea dissolved in water, AdBlue, and in a diesel tank that leads to corrosion and build-up.
Our engineers handle both, and AdBlue removal in Quarryhead has its own page with the full story — including why it is often the more serious of the two.
How much is a petrol-in-diesel drain in Quarryhead?
One price would not be fair here, as this is not one job. These are the things that shift it:
- Whether the motor has been run or driven. This is the key one.
- Wrong fuel in, against what that tank holds — that ratio.
- Whether it was unleaded or AdBlue.
- Whether a van can sensibly reach the vehicle and work on it, which hinges on where your car is.
A firm answer instead of a range is what you get for telling us three things: the vehicle, the amount, and if it has run. If it's not pressing — the vehicle is at home and going nowhere — is fine too.
Petrol in diesel: frequent queries around Quarryhead
At a petrol station in Quarryhead, can you do a fuel drain there?
Yes — forecourts are where a large portion of this happens. We visit another forecourt nearby and the other forecourts nearby routinely, with the owner's consent — tell us which one you are at when you ring and we will tell you whether we can work there.
Is there a safe amount of petrol in a diesel?
It hinges on the ratio rather than the litres, and a lot more on whether the engine has run. Five litres into an almost dry tank isn't five into a full one, no. But both land on the same query in the end: has that mix been sucked right through, or has it not?
Already driven it with petrol in your diesel? Now what?
Switch off somewhere sensible, then keep it that way after you stop. It is salvageable much more commonly than people fear, even though driving is what shifts the trouble from your tank into your pump and injectors — and the single most valuable thing you can do now isn't restart it.
My warranty — does a fuel drain void it?
A drain then flush carried out correctly is not a modification and 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 dispute with one.
Can I just add two-stroke oil and drive home?
No. It belongs to a distinct issue from a separate era, and petrol has weakened something no oil of that kind replaces. Your pump still has to put up with it, since the tank still has petrol in it later.
Main dealers and petrol in a diesel
Wherever the car is, we drain and flush it there, so a visit to the main dealer does not come into it.
You, and the vehicle, still together?
Keep the engine turned off.
Driven it already? Then somewhere safe, stop, switch off, and no restarting it later on. Cold and parked, a car is in the best place available — and drivers fear this much more than the recovery rate warrants.
Throughout Midlothian and in Quarryhead: on-site fuel draining, at home or on the forecourt or at the roadside.
