Low Common: Put Petrol in a Diesel Car?
With that tank still holding the petrol and your engine not yet turned over, almost every job takes only a drain, so leave the motor off. That result is determined in the minutes right after the fill-up, rather than by the amount that went in. Throughout Low Common and the rest of West Yorkshire, Petrol in Diesel drains your car and flushes it where it sits, whether at a roadside, on a driveway or at a forecourt. Ring us before everything else begins, and you'll hear what happens after that.
The first five steps: petrol in a diesel
- Do not crank it. Started all the same? Then don't rely on it. Diesel in a petrol motor generally cannot run, so the driver stops and the damage stops with them. Petrol in a diesel? It starts. It ticks over. It pulls away fine, for a few miles. Most people get that muddled. It isn't okay — that fuel system is wearing every mile you do.
- Switching the car's ignition on often primes that system, and priming is what moves petrol out of that tank and into the pump and injectors. Those are the components diesel keeps greased on its way through, before it ignites. Petrol handles the burning and none of the protecting. Leave the car's ignition alone.
- Topping up removes nothing. It leaves you a bigger tank of the same mix, because a diesel fuel system won't accept petrol by percentage as that guidance suggests — so do not put diesel on top to water down it. Grade is immaterial too: super unleaded is petrol.
- Stay still if it is sensible to. Hazards on, motor off, leave it. Wherever you have stopped — the verge on Aston Court, anywhere — a difficult place for us beats a started diesel, and nothing is simpler for us to sort than a car that never moved.
- Have your whereabouts ready before you phone. A postcode that starts WF5 0 and whatever is closest to you with a label on it is the difference between our van arriving and the van circling.
- Call 0333 366 0103. Let us know what got in, approximately how much, plus if the engine has fired. Those three answers decide your whole job.
Can petrol be pumped out of your diesel at a forecourt?
Much of the work starts at a forecourt, which means a fair share of it gets completed on site. Still at Shell? Then that's generally where it gets done. Petrol station forecourts are everyday for us, with the consent of the station.
No place but a forecourt can it be caught with the engine still cold. The few seconds between seeing your receipt and going for the keys settle how much requires flushing. Anywhere other than the forecourt — a car park, a driveway, a lay-by — the vehicle was started and driven to get there, so fuel was pulled from the tank, through the filter and into the high-pressure fuel pump. That means the lines and the fuel filter need rinsing as well as the tank. It's not a calamity, and we can still put it right where the car is.
Wheel it out of the way if the attendants volunteer, and they generally will. The next motorist gets past the petrol pump, and that's worth doing. Firing the car just for four car lengths? Don't.
We're in car parks like the one at Co-op Food often, and it's rarely the fuel that complicates them. It is the bay. Motors both sides. Trolleys stacked up behind. At times a height barrier at the way in, which decides if our van reaches you at all. So say how penned in you are when you call, and which way the vehicle is pointing. If there is no space to work beside the BMW 3 Series, we shift it without the motor. That is not fussiness over a few seconds: starts prime things, fuel comes out of your tank on to the pump, and a vehicle shifted twice for a better spot is quietly a bigger job than one no one touched.
Move it out of the gateway and deal with it later — that's what somebody will say, and it's wrong. Parked on the zig-zags at Ossett South Parade Primary, a misfuelled diesel Peugeot 308 is a hassle and nothing worse. Started three more times for courtesy, it's no longer a tank problem but a fuel system one, since priming takes place with every start and more petrol goes through your filter on to your pump. Let people complain. Phone us.
Why so firm about leaving the keys alone? Since the pump is upstream of the injectors, and a wearing one sends whatever it loses on with the fuel. Ring us. Leave the Kia Sportage by South Ossett Baptist Church.
Hire car? Company car? Call them before us. Some agreements want the firm to sign off the work, and that is much faster dealt with up front than after that. Then call us about the Ford Fiesta, the diesel one, close to Otterflow Pilates & Yoga. Don't worry that you cannot say how full that tank was — almost no one can two days into a motor, and it's something our engineers work out on site. The reason for asking: damage from petrol in a diesel is a matter of proportion. A couple of litres in an almost empty tank make a far stronger mix than in a full one, and petrol is built to resist the very thing a diesel needs of that, which is igniting when compressed. Stronger mixture, more rattling, more smoke, flatter throttle.
A few streets, then it stopped. Throttle soft, idle uneven, and the diesel Vauxhall Insignia is parked up by Ossett Spa. The motor is not failing — that softness is fuel that will not build pressure. There's no light on the dash for it, so motors like yours normally get driven once more before somebody picks up the phone. Don't. Off, and call us.
Areas our vans reach near Low Common
The same rounds carry us to Haggs Hill, Ossett Spa, Spring End, South Ossett and Shepherd Hill besides Low Common, which is a residential suburb.
If yours is not on this list it does not mean we never come — there are pages for nearly all places across West Yorkshire, and the ones mentioned above are simply the closest neighbours. Phone to ask instead of assuming — county lines especially, and anywhere your phone might get wrong.
The ground this page covers is on our map. Your vehicle never needs to come to us. We operate over all of it — roadside, forecourts, driveways, car parks.
Stopped by the roadside anywhere around Low Common?
Not everyone gets a chance to stop somewhere sensible. A normal call for us rather than an odd one: noticed after setting off, ended up by the verge of Teall Street or at a lay-by with the hazard lights on.
Sit by the vehicle if it is sensible to sit inside, and out of it if it is not. Don't restart the motor to nurse the car somewhere handier — a diesel running on petrol will usually oblige, and every mile it obliges for is drawing the mixture further into the system. We'll send our van to an awkward location without any trouble, and for the vehicle that is much better than pressing on.
Already run it? Petrol in a diesel after a couple of miles
The local M1 is the one which matters here, and sits under a mile from Low Common. A wrongly fuelled diesel will frequently get you onto it and some way along before anything feels wrong, and the signs when they come are usually a drop in power, a lumpy idle and some smoke instead of a neat stop.
Take the next junction that is sensible, pull up there, and do not start the vehicle to reposition. Assume the worst of it on a long trip. Anything close to the under 3 miles to the nearest city, and the petrol has been through your filter, through your pump, through the fuel injectors. Say so when you ring. What our engineers bring differs.
Where is Low Common?
Low Common is a suburban area located near Wakefield in West Yorkshire, sitting at an elevation of 62 metres in a generally flat inland setting. Low Common is characterized by its predominantly semi-detached housing stock, with nearby amenities and services in Wakefield. Low Common is close to other local places such as Haggs Hill and Ossett Spa, and is situated about 2.5 miles from Wakefield city centre.
Once our technicians reach you in Low Common: what happens
- Our technicians ask first, quote after. What was put in? How much? Has the motor run? Those replies shape what the work really is.
- That tank is emptied completely.
- Lines flushed, filter cleared. Whatever remains later on isn't the thing that created the trouble.
- Priming follows, once fresh diesel is in.
- We turn it on and make sure it runs smoothly on clean diesel.
That leaves your car ready to set off. There's no need to go to a garage at any stage, since the work is all done where the car is, and when it is caught early, lasting damage is very uncommon.
A different matter: AdBlue in a diesel tank in Low Common
The problem is not the same, though the opening rule is — do not crank it — if what went in was AdBlue instead of petrol. Petrol does two things to diesel: weakens it, and takes away the lubrication the system relies on. AdBlue is urea in water, and in a diesel tank it brings corrosion and build-up in its place.
AdBlue removal around Low Common has a page of its own with the full story on it, including why it is often the more serious of the two. Our engineers deal with both.
Low Common prices for a petrol-in-diesel drain
One price would not be honest here, as this is not one job. These are the things that shift it:
- Whether the motor has been started or driven. This is the main one.
- How much of the wrong fuel went in, set against how much your tank holds.
- Which got in: petrol or AdBlue.
- Access: the car's position, and if working on it there is safe for our van.
A straight answer rather than a range is what you get for telling us three things: your vehicle, the quantity, and whether it has run. If it isn't time-critical — the car is at home and going nowhere — works too.
Petrol in diesel queries from Low Common drivers
At a petrol station in Low Common, can you do a fuel drain there?
A fair part of this work gets done there, so yes. Often, provided the site consents: Murco, plus every other forecourt nearby. Say on the phone where exactly you have stopped. Whether we can work in that spot is something our technicians answer straight away.
How much petrol in a diesel is too much?
Ratio decides it instead of litres — and more than either, whether your motor 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 drawn right through, or has it not?
I drove the car after putting petrol in my diesel. What next?
Stop safely. Off. Nothing after that. Not restarting it is the single most useful thing available to you now. Driving does move the problem out of the tank and into the pump and injectors, yes, and it stays salvageable far more commonly than people expect.
My warranty — does a fuel drain void it?
It is not a modification, and so a drain and flush carried out correctly does not cancel a manufacturer's warranty. An argument over a warranty is likelier to come from running a diesel on petrol — so leave it switched off.
Two-stroke oil in your tank, and then home?
No. It belongs to a different fault from a separate era, and petrol has weakened something no oil of that kind restores. Your pump still has to live with it, because that tank still has petrol in it afterwards.
A main dealer for petrol in a diesel — essential?
You do not need one. The vehicle is drained and flushed wherever it is, with no need to take it to a franchised dealer.
You, and your vehicle, still together?
Leave it switched off.
Switch it off somewhere sensible then leave it off, if you have already driven it. Cold and stationary, a vehicle is in the best place available — and people fear this a lot more than the recovery rate warrants.
