Put Petrol in a Diesel Car in Irlam? Don't Start It
Petrol in Diesel drains and cleans misfuelled vehicles where they sit, on the forecourt, at the roadside or on a private drive, throughout Irlam and the rest of Greater Manchester. The first thing to do is not to turn on your engine. While the motor has not yet run and the petrol is still sitting in your tank, a tank drain is almost always all it takes, and the following few minutes settle that, not how much was put in. Call us before all else starts, and you will learn what happens after that.
What next? Petrol in a diesel, step by step
- Never start it — and do not rely on it if it runs. Here is the thing most people have wrong about petrol in a diesel in particular. A petrol motor fed diesel typically just cannot run, and so the driver stops and the harm halts with them. A diesel given petrol generally starts, ticks over and drives off just fine for several miles. It is not all right. It is wearing that fuel system as you drive.
- Two things, diesel: it burns, and on the way through it keeps the injection pump and injectors greased. Petrol only handles the one. Which is why the ignition remains off as well — flick it on and you commonly prime your system, and that is petrol exiting your tank for precisely those components.
- Don't add diesel on top to dilute it. A diesel fuel system won't accept petrol by percentage the way that guidance assumes, and topping up gets rid of nothing — it just hands you a fuller tank of the same mixture. The type makes no difference either: super unleaded is simply petrol.
- Stay put if it's safe to. Hazards on, motor off, keep the car. Wherever you have stopped — the verge on Fiddlers Lane, anywhere — an odd location for us beats a started engine, and nothing is easier for us to handle than a motor that never shifted.
- Keep your location ready before you phone. A postcode beginning M44 6 and whatever is nearest to you with a sign on it is the difference between our van arriving and a van circling.
- Three facts settle the entire visit: the fuel you put in, the approximate quantity involved, plus if anything has been turning since. The number is 0333 366 0103.
The high-pressure pump spent that morning commute working on a fuel that had given up much of the protection it is made for. Diesel lubricates that pump, and the injectors with it, before any of your fuel burns; petrol does the burning and none of the lubricating. So take a diesel Volkswagen Tiguan, fuelled at quarter past eight, taken in to work, and left standing at Flixton till it dawns on you around eleven. Three hours of sitting have altered nothing about it. The couple of miles before that altered plenty, which is why the question our engineers ask you is about distance rather than hours. Phone us. Keep it exactly where it is.
If you have put petrol in the diesel Skoda Octavia in Irlam and you are now sat outside Spar with a boot full of shopping, call us. Don't crank it a second time to get out of that spot. We will come to you, drain the tank, flush your fuel lines then put clean diesel in so you can drive away. A mile or so at easy throttle pulls very little diesel, so those are usually the simple jobs.
A diesel pump delivers fuel to demand, and a hurried morning run needs plenty — so three miles in your Mercedes C-Class feels like nothing and isn't. Twenty to nine outside Fiddlers Lane Community Primary School, running late, the receipt in your hand reading unleaded: hazards on, engine off, phone.
About as well as this goes, once your engine has turned: away from the pumps, receipt read, and your diesel Kia Sportage parked close to Irlam Library barely two streets on. Phone us, then leave it off. A short distance does genuinely help. It was still a start and still a drive, though, so the filter and your pump have had weakened fuel through them — hence cleaning the lines rather than only emptying that tank.
Someone confident will tell you to drain it and put clean diesel in. Half right, that. Try it on a diesel Volvo XC60 close to St John's and the motor will start — which is exactly why it sounds like sense. Here is the catch: there is petrol left in your filter and the feed lines, and the first thing the engine does is draw it back through your pump once more. Draining a tank achieves nothing about fuel that already left the tank. Ring us. Your circuit gets rinsed, your filter comes off where there is one worth removing, and that's what separates a repaired motor from one that only starts.
Clearing petrol from the diesel on the forecourt
Plenty of this work starts at a pump, meaning a fair portion of it gets completed on site. Still at Shell? Then that is typically where it happens. Petrol station forecourts are everyday for us, with the agreement of the station.
Before your motor has started — a garage is the only location it is spotted. Anywhere else — a car park, a private drive, a lay-by — the vehicle was started and moved to get there, which means fuel was drawn from your tank, through your filter and into the high-pressure pump. That is not a catastrophe, and our technicians can still deal with it where it is. It does mean your lines and the filter need rinsing as well as your tank, and that's determined by the few seconds between seeing the receipt and going for the keys.
Away from the pump, the next driver can get past — so yes, let the staff help you move the vehicle. Well worth doing. Four vehicle lengths is not worth a restart.
Areas our team cover near Irlam
Woods End, Calder Bank, Flixton, Carrington, Crofts Bank — all of them on our trips that bring us across to Irlam too, a riverside town.
Not on the list? It tells you nothing. The names above are just the nearest few, and most places around Greater Manchester have a page of their own somewhere on this site. Guessing is the mistake to resist, particularly on a boundary or anywhere the satnav fails. Call us and enquire.
This map marks the area the page covers. Kerbside, forecourt, drive, car park: every bit of it is territory we serve, and none of that requires the car to travel to us.
Broken down at the roadside around Irlam
Not everybody finds a safe place to pull over. A normal call for us rather than an odd one: noticed after setting off, landed along the verge beside Dairydale Close or in a lay-by with the hazards on.
Whether you stay beside the motor or move away from it depends on if staying nearby seems safe. It will usually oblige. A diesel running on petrol limps along quite willingly, and that is the trouble: fire it up to get to somewhere better and the mix goes further into the system with every mile covered. However inconvenient the location, it is no problem for us to come to it, and that's far better for your car than pressing on.
Run it already? Stop, then read this
This is where the local M62 comes in — under a mile away from Irlam. A drop in power, an uneven idle, smoke: those are the signs when they arrive, rather than a tidy stop — and a misfuelled diesel will usually take you onto it and some distance along before anything seems wrong at all.
Don't start it to reposition. Get off at the first sensible junction and turn off. It alters what our technicians bring, so tell us when you ring: on a longer run — anything close to the under 10 miles to the closest city — assume the contamination has been through the fuel filter, your pump and the fuel injectors.
Irlam itself
Irlam is a town situated on the banks of the River Irwell in Greater Manchester, with a population of around 16992 people. Irlam lies approximately 5.2 miles southwest of Salford and 165.2 miles northwest of London, at an elevation of 22 metres. Irlam is characterised by its semi-detached housing stock and is near to other local places such as Woods End and Flixton. Irlam's riverside setting has influenced its development over time.
What our technicians do when our engineers arrive with you around Irlam
- Our engineers ask first, quote after. What went in? How much? Has the motor run? Those responses alter what the work really is.
- The contaminated mixture comes out of the tank.
- Fuel lines are purged through and the filter cleared, leaving nothing in your system that caused any of this.
- Bleeding your system follows, once clean diesel is in.
- The engine is fired up and tested to be sure it runs properly on new diesel.
The vehicle is then ready for you to pull away. Permanent damage is very unusual when it has been caught soon, and since everything is done where the vehicle is, it never needs to go to a garage.
AdBlue in the diesel tank instead, around Irlam?
Do not start it: that opening instruction holds whether what got in was AdBlue or petrol. What differs is the fault itself. Thinned diesel, and no protection left for your fuel system that relies on it. That is petrol. AdBlue? Urea dissolved in water. Pour that in with your diesel and you get rust instead, plus deposits.
Our engineers cover both, and AdBlue removal around Irlam has its own page with the details — including why it's frequently the more serious of the two.
How much is a petrol-in-diesel drain in Irlam?
One number wouldn't be honest here, as this is not one job. These are the things that move it:
- Whether the engine has been run or driven. This is the key one.
- The tank's capacity, set against how much of the wrong fuel got into it.
- Which got in: unleaded or AdBlue.
- Whether a van can sensibly get to your vehicle and work on it, which rests on where your car is.
A firm answer instead of a range is what you get for telling us three things: your car, the quantity, and if it has run. Not pressing, with the vehicle at home and going nowhere? Then works.
Things we get about petrol in diesel in Irlam
I'm on a forecourt in Irlam. Can you drain it on the spot?
A good portion of this work takes place there, so yes. Routinely, provided the site agrees: Texaco, plus every other forecourt nearby. Say on the phone where precisely you have stopped. Whether we can work in that spot is something our engineers answer there and then.
How much petrol in a diesel is too much?
Litres aren't the measure. Proportion is, and far more than either, it matters if anything has been run. Five litres in an almost empty tank is a distinct case from five in a full one — but either way, the thing that determines how much work is needed is if that blend has been pulled through the system.
I drove it after putting petrol in my diesel. What next?
Somewhere safe, then stop, then turn off and leave it off. Driving is what moves the trouble from your tank into the pump and injectors — but it's recoverable much more regularly than drivers fear, and the single most useful thing you can do now isn't restart it.
Is a fuel drain going to void my warranty?
No. Carried out properly, clearing and cleaning is no alteration at all, and the warranty from your manufacturer is unaffected by it. A dispute over a warranty is likelier to come from running a diesel on petrol — so leave it turned off.
Can I just add two-stroke oil and drive home?
No. It belongs to a different issue from a separate era, and petrol has weakened something no oil of that kind replaces. Petrol stays in that tank later, whatever else goes in, and the pump gets no break from it.
Do I need a main dealer for petrol in a diesel?
You don't need one. Your car is drained and flushed wherever it is, with no need to bring it to a main dealer.
Still with the car?
Your engine remains off.
If you have already driven the car, pull in somewhere sensible, turn it off and leave it off. This is recoverable from far more commonly than people fear, and a parked, cold motor is the best position to be in.
