Petrol in a Diesel Car in Methven
With that tank still carrying the petrol and the motor not yet started, almost every job takes only a drain, so leave the engine off. That result is determined in the minutes immediately after the fill-up, and not by the amount that got in. Throughout Methven and the rest of Perth and Kinross, Petrol in Diesel drains the car and flushes it where it stands, whether by a roadside, on a driveway or at a forecourt. Phone before anything else begins, so you'll hear what follows next.
What to do first about petrol in a diesel
- Whenever you drive, the pump and the injectors suffer. This is why you do not start it, and why you don't rely on it once it has started. The thing about petrol in a diesel specifically — the part most people get wrong — is that it drives away happily for the first mile or two. Diesel in a petrol engine usually cannot run at all, which stops the driver and stops the damage with them. This one lets you carry on.
- Turning the ignition on commonly primes your system, and priming is what pulls petrol out of that tank then into the pump and injectors. Those are the components diesel keeps protected on its way through, before it ignites. Petrol handles the burning and none of the protecting. Leave the car's ignition alone.
- Do not weaken it. Diesel put on top takes out nothing, and so all you get is more of what was already there, because percentage is not how a diesel fuel system tolerates petrol. Super unleaded? Simply petrol. The grade makes no difference.
- Wait where you are if you safely can. A car that has never moved is the simplest one to sort, and our team would sooner get to a tricky spot than have it started. If you are parked on the verge on The Square, turn your hazards on then keep the vehicle there.
- Before you call, get your location. Anything nearest to you with a sign on it, plus a postcode starting PH1 3 — that's what determines whether the van shows up or circles.
- What went in, roughly how much, and also if the motor has started — the three replies shape the whole visit. Phone 0333 366 0103 and tell us.
At a forecourt: clearing petrol from a diesel
Forecourts are where this job mostly kicks off, and where a fair chunk of that closes. Still at Almondbank Filling Station? Then that's typically where it gets done. Station forecourts are normal for us, with the permission of the station.
No place other than the forecourt can this be stopped with your motor still cold. Everywhere else — a car park, a drive, a lay-by — the car was started and moved to get there, which means fuel was sucked from that tank, through the fuel filter and into your high-pressure pump. That's not a disaster, and our engineers can still sort it out where it stands. It does mean the lines and the fuel filter need cleaning as well as your tank, and that's settled by the few seconds between checking the receipt and going for the key.
Push the car out of the way if the attendants volunteer, and they generally will. The next driver gets past the pump, and that is worth doing. Moving the car four lengths does not warrant cranking the engine.
Our technicians will get to you, drain your tank, purge your fuel lines then put fresh diesel in so you can drive home. So if petrol went into the diesel Audi A4 in Methven and you're stranded at Tesco Extra with a boot loaded with shopping, call us — and never crank it again to leave the spot. A mile or so at gentle throttle draws little fuel, so such jobs tend to be the simple ones.
How far, and how hard? The second of those counts more than the first, so have both prepared. Your Dacia Duster will have seemed perfectly ordinary on the way back from the local primary school — they all do, and that's the snag. Diesel into a petrol vehicle mostly will not run at all: the person stops, and so does the harm. Petrol into a diesel fires up, ticks over, pulls away like nothing happened, whilst the high-pressure pump gets on with its work minus the protection your fuel should be giving it. No warning arrives, as behind the wheel nothing looks wrong.
Our technicians rinse the lines instead of only draining your tank, and the reason is that thinned fuel has already reached the filter and the pump: it was a start and a drive, however short. The drive truly helps — pulled off the forecourt, receipt read, a diesel Ford Kuga parked up close to Methven and Logiealmond Church a couple of hundred yards later is about as well as this goes once the engine has turned. Ring us then leave it off.
Petrol in a diesel does its harm as a proportion, which is the reason our technicians ask at all: the same few litres waiting in an almost empty tank make a far stronger mixture than they would in a full one. And petrol is rated on how well it withstands igniting under pressure — the opposite of what a diesel wants — so a stronger mix knocks more, smokes more, goes flatter. None of which means you need an answer ready. Nearly no one knows how full your tank was in a motor collected two days ago, and our technicians work that out on the spot. Do phone the hire or company firm first, though: some contracts want them to sign off the work, and that's far faster settled before than after. Then ring us about the Citroen C3 by Methven Community Centre.
What takes place next is the issue. Your engine immediately sucks the petrol left sitting in the filter and the feed lines back round through your pump a second time, since emptying a tank does nothing about fuel that has already left it. Drain it and put clean diesel in, somebody certain will tell you — and that suggestion is only half right, as do it to a diesel Kia Sportage parked up, Needburn say, and the thing starts, which is what makes it sound sensible. Call us instead. Our engineers flush the circuit and take the filter off where the vehicle has a working one, and that's the difference between the vehicle being put right and your car merely starting.
Methven and the villages beside it
The same journeys carry us to Braegrum, Tibbermore, Almondbank, Pitcairngreen and Lochty as well as Methven, which is a village.
If yours is not on this list it doesn't mean we do not come — there are pages for the majority of towns around Perth and Kinross, and the ones named above are just the nearest neighbours. Phone and check instead of presuming, especially if you are on a boundary or anywhere your phone can't find.
That map outlines the patch this page spans. Your car never needs to travel to us. We work across every bit of it — kerbside, forecourts, driveways, car parks.
Stuck by the kerbside somewhere around Methven?
Not everybody gets a chance to pull over somewhere safe. Hazards flashing at a lay-by somewhere, or stopped on the verge beside College Road as you worked it out after setting off — we take that call often enough that it's the usual kind.
Fine where you are? Remain beside it. Not fine? Step out and clear of it. Every mile a diesel obliges you for on petrol drags the blend further into your fuel system — and oblige it usually will, which is why the motor doesn't get restarted to limp somewhere safer. We'll bring our van to a difficult location without any trouble, and for the car that is a lot better than pressing on.
Some miles on petrol in a diesel: what now?
under 5 miles out of Methven, the M90 is what matters here. Some way along, and onto it in the first place: a misfuelled diesel will usually do both before anything seems wrong. What you get then is seldom a clean stop. Power ebbs away, the idle gets rough, and there may be smoke.
The first safe junction is the one to take. Turn off there, and leave the restarting alone. On a longer drive — anything close to the under 10 miles to the nearest city — take it the mixture has been through your filter, the pump and your injectors, and tell us when you ring. It alters what our engineers bring.
Where is Methven?
Methven is a village situated on the banks of the River Almond in Perth and Kinross, Scotland, with a population of around 1317 people. Methven sits at an elevation of 66 metres, close to the city of Perth, which is approximately 5.6 miles away. Methven has a mix of housing types, but detached homes are the most predominant. Methven is located near other small settlements, including Braegrum, Tibbermore, and Almondbank.
What comes next when we reach you in Methven
- Our technicians establish what went in, how much, and if your motor has run. The replies alter the work, which is why our engineers ask before pricing.
- The tank is drained of it.
- Fuel lines are cleaned through and your filter cleaned, leaving nothing in the system that started any of this.
- Our engineers pour fresh diesel in and bleed the system.
- It's run with new diesel in it, and our technicians make sure that it's running correctly.
After that it is ready to drive away. Our engineers do all of it wherever the car has ended up, which means it never needs to go to a garage, and if it has been noticed quickly, it's very rare for there to be lasting damage.
AdBlue in a diesel tank in Methven is a distinct problem
If what was put in was AdBlue instead of petrol, the first rule is unchanged — do not crank it — yet the issue is not. Diluted diesel, and no protection left for your fuel system that relies on it. That is petrol. Urea dissolved in water, AdBlue, and in a diesel tank that causes rust and deposits.
Both are ours. There is a separate Methven page for AdBlue removal, with the detail on it — including the reasons it frequently turns out to be the worse of the two.
How much is a petrol-in-diesel drain around Methven?
What shifts the price is set out below, since this job isn't one job and our technicians cannot truthfully put a single figure on this page.
- Whether your engine has been run or driven. This is the key one.
- How much of the wrong fuel went in, set against how much the tank can hold.
- Whether it is unleaded or AdBlue.
- Where is it? And can a technician reach it and work there sensibly?
Tell us what your vehicle is, how much went in, and if the motor has run. A firm answer comes back, not a range. For your car at home that is going nowhere and isn't pressing, is fine too.
Petrol in diesel questions from Methven motorists
Fuel drains on a Methven petrol station forecourt
Much of what our technicians do takes place nowhere else. So yes. Tell us which one you're at when you call and we will tell you if we can work there. With the station's agreement our technicians attend Burnbrae Garage and the other forecourts locally all the time.
A few litres of petrol in a diesel — too much?
Whether the engine has run matters far more, though the proportion counts too, rather than the litres. 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 mixture been sucked right through, or has it not?
Petrol in my diesel, and I have driven the car
Pull over somewhere safe, turn off, then keep the vehicle off. Not restarting it is the single most helpful thing available to you now. Driving does move the issue out of the tank then into your pump and injectors, yes, and it stays recoverable much more regularly than motorists expect.
Will a fuel drain void my warranty?
A drain and flush carried out correctly is not a change and does not 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 disagreement with one.
Adding two-stroke oil, then driving home
What petrol has diluted is not restored by two-stroke oil, which is an old remedy for a distinct problem. So no. Petrol stays in that tank later, whatever else goes in, and your pump gets no break from it.
Main dealers and petrol in a diesel
Wherever the car is, we drain and flush it there, so a drive to the main dealer does not come into it.
You, and your car, still together?
The engine stays off.
Driven it already? Then somewhere safe, stop, turn off, and no restarting it later on. A parked, cold car is the best position to be in, and this is recoverable from far more regularly than people fear.
