Shortwood: Put Petrol in a Diesel Car?
Petrol in Diesel drains and cleans wrongly fuelled cars where they sit, on the forecourt, at the roadside or on a private drive, throughout Shortwood and the remainder of Gloucestershire. The very first thing to do is not to start the motor. While the motor has not run and the petrol is still sitting in the tank, a drain is almost always all it needs, and the following few minutes determine that, not how much got in. Our technicians will tell you what your next move will be. Ring us — this comes before all else.
Petrol in a diesel: what to do now
- Do not crank it — and never rely on it when it does start. That is the bit motorists get wrong about petrol in a diesel specifically. A petrol engine filled with diesel generally just cannot run, and so the person stops and the damage halts with them. A diesel given petrol typically starts, idles and moves off just fine for a couple of miles. It is not fine. It is wearing out that fuel system while you drive.
- Diesel combusts, and before it combusts it lubricates — that high-pressure fuel pump, the injectors. Petrol handles only the burning. So leave the car's ignition off also: switching it on is usually all it takes to prime that system, and priming carries petrol from that tank into just those components.
- Topping up takes out nothing. It leaves you a fuller tank of the same blend, since a diesel fuel system doesn't cope with petrol by percentage in the way that guidance presumes — so don't add diesel on top to dilute it. Octane is irrelevant too: super unleaded is petrol.
- Sit tight if it is wise to. Hazards on, ignition off, keep the car. Wherever you have stopped — the verge on Pike Lane, anywhere — a tricky spot for us beats a started diesel, and nothing is easier for us to handle than a vehicle that never moved.
- Have your location ready before you dial. A postcode starting GL6 0 and whatever is next to you with a sign on it is the difference between a van arriving and a van circling.
- Phone 0333 366 0103. Let us know what was put in, approximately how many litres, and if the engine has fired. Those three facts determine the whole call-out.
Can petrol be pumped from a diesel at the forecourt?
A large part of this job gets finished at a pump, because that's where it mostly begins. If you are still at the forecourt at Shell, that's typically where this drain takes place — we work on petrol station forecourts routinely, with the site's consent.
At a forecourt, the mistake gets spotted with your motor never run, and nowhere else manages it. Anywhere else — a car park, a private drive, a lay-by — the car was switched on and moved to get there, which means fuel was sucked from that tank, through the fuel filter then into your high-pressure pump. That's not a disaster, and our technicians can still put it right where it sits. It does mean the lines and your filter need cleaning as well as the tank, and that is settled by the few seconds between checking the till receipt and going for the keys.
Staff will normally pitch in pushing it clear of the petrol pump, which lets the next customer get past. Take the help. Four vehicle lengths is not worth a start.
Can we serve your corner of Shortwood?
Shortwood is a residential suburb, so our technicians get out to the town and to the areas around it on the usual runs: Newmarket, Worley, Wallow Green, Walkleywood and Rockness.
If yours isn't on this list it does not mean we never come — there are dedicated pages for the majority of locations in Gloucestershire, and the ones listed above are merely the closest neighbours. Guessing is the thing to avoid, especially on a border or somewhere a satnav fails. Call us to ask.
See the map for the ground covered on this page. We operate roadside, at forecourts, on driveways and at car parks throughout all of that, and the vehicle never needs to come to us.
Your diesel Nissan Qashqai will have felt perfectly usual on the way back from Nailsworth Church of England Primary School. They all do, and that's the catch with petrol in a diesel rather than the other way round. Put diesel in a petrol vehicle and it mostly will not run, so the person stops and the wear stops with them. Put petrol in a diesel and it fires up, idles and moves off as though nothing has happened — all while the high-pressure fuel pump does its work without the protection the fuel is supposed to be providing. Nothing alerts you, because from behind the wheel there's nothing to warn you about. Phone us with approximately how far you travelled and how hard you pushed it; the second answer matters more than the first.
A diesel Vauxhall Astra sitting in the parking area outside The George Inn with a tank of petrol in it is a simple job, right up until someone drives it home. Park the vehicle there overnight and phone us first thing. Nothing deteriorates while it waits. What we will ask is if the drive there was brief and chilly, since that's where petrol is slowest to burn correctly — and anything that won't burn can work past the rings then into the oil.
Out there fine, back flat. If that was the drive to Queen Elizabeth Field, look at that tank. Diesel gets thinned by petrol, and thin fuel seeps past the close clearances supposed to build injection pressure — so every additional mile your diesel Mercedes A-Class covered, the less pressure it held onto. Somewhere sensible, turn off, call us.
About as well as this goes, once your engine has turned: away from the pumps, receipt read, and the diesel Citroen C3 left close to Arkell Community Centre barely two streets on. Ring us, then leave the vehicle off. A short distance does truly help. It was still a start and still a drive, though, and so the filter and the pump have had weakened fuel through them — hence cleaning the lines instead of only draining the tank.
Hire car? Company car? Phone them before us. Some agreements want the firm to approve the work, and that's much quicker dealt with up front than after that. Then phone us about the Kia Sportage, the diesel one, near The New Lawn. Do not worry that you can't say how full the tank was — almost nobody can two days into a motor, and it is something our technicians check on the spot. The reason for asking: harm from petrol in a diesel is a matter of proportion. A couple of litres in an almost empty tank make a far stronger blend 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 mixture, more rattling, more smoke, flatter throttle.
Stuck on the kerb anywhere in Shortwood?
Not everybody finds a decent spot to stop. Set off, then realised? Finished up on the verge on Homefield, or sat in some lay-by with the hazard lights going? That's a common call here. Not a rare one.
Okay there? Stay with it. Not fine? Step out and away from it. Do not restart your engine to limp the vehicle somewhere safer — a diesel running on petrol will often oblige, and every mile it obliges for is pulling the mixture further into the fuel system. Pressing on does the vehicle far more harm than our van coming out to an inconvenient place, and that is no problem for us.
Driven it already? Stop, then see this
This is where the local M5 matters, under 10 miles from Shortwood. A misfuelled diesel will often take you onto it and some way along before anything seems wrong, and the signs when they appear are normally lost power, a rough idle and some smoke rather than a neat stop.
Come off at the next sensible junction, switch off, and do not start the vehicle to reposition. It alters what we bring, and so mention it when you call: on a longer run — anything approaching the under 15 miles to the closest city — assume the petrol has been through the filter, your pump and your injectors.
Shortwood itself
Shortwood is a suburban area in Gloucestershire, situated on the riverside at an elevation of 113 metres. Shortwood lies near the cities of Gloucester and the surrounding villages of Newmarket, Worley, and Wallow Green. Shortwood has a population of approximately 1748 residents, predominantly living in semi-detached housing. Shortwood is located 91.3 miles west of London, in the South West region of England.
What happens when our engineers reach you in Shortwood
- Three things get established before any price — the fuel that was put in, the amount, and whether anything has been run since. Each answer shapes the work.
- The tank is emptied completely.
- Lines purged, filter cleared. Whatever is left after that isn't the thing that started the problem.
- The fuel system gets bled, on new diesel.
- Once it's fired up, our technicians confirm it runs smoothly on new diesel.
The car is then ready for you to pull away. Permanent damage is very uncommon when it has been spotted early, and since all of this is done where the vehicle is, it never has to go to a garage.
A distinct job: AdBlue in a diesel tank around Shortwood
If what was put in was AdBlue instead of petrol, the first step is the same — do not crank it — but the problem is not. Weakened diesel, and no lubrication left for the fuel system that relies on it. That is petrol. Urea in water, AdBlue, and in a diesel tank that leads to rust and deposits.
We deal with both, and AdBlue removal around Shortwood has its own page with the detail — including why it's often the more serious of the two.
How much is a petrol-in-diesel fuel drain in Shortwood?
Honestly, no single figure belongs on a page like this. The job changes. Here is what moves it:
- Has it been run or driven? Nothing else matters for as much.
- How much of the wrong fuel was put in, measured against how much that tank takes.
- AdBlue or petrol, whichever went in.
- Where is it? And can a technician reach it and work there sensibly?
The car, the quantity, whether it has run — give us those and the answer comes back firm instead of as a range. Vehicle at home, going nowhere, nothing pressing about it — is fine for that.
Petrol in diesel questions from Shortwood motorists
Fuel drains on a Shortwood petrol station forecourt
A fair portion of this work happens there, so yes. Regularly, provided the site agrees: Esso, plus every other forecourt nearby. Say on the phone where exactly you have stopped. Whether our technicians can work in that spot is something our technicians answer there and then.
A couple of litres of petrol in a diesel — too much?
Ratio settles it instead of litres — and more than either, whether your motor has run. A nearly empty tank with five litres in it, against a full one with the same five: separate situations, of course. Either way, the work needed comes down to one thing, which is if the fuel system has had that mix drawn through it.
I drove the car after putting petrol in my diesel. What now?
Stop sensibly. Off. Nothing after that. Driving shifts the trouble along — out of your tank, into your pump and injectors. People fear it a good deal more than the recovery rate warrants, mind. The one truly useful thing left to you is not restarting it.
My warranty — does a fuel drain void it?
A manufacturer's warranty withstands a drain and flush done to a correct standard, which is no alteration at all. Another reason to leave it switched 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?
No. It belongs to a separate fault from a bygone era, and petrol has diluted something no oil of that kind puts back. Petrol remains in that tank afterwards, whatever else goes in, and your pump gets no respite from it.
A main dealer for petrol in a diesel — essential?
Wherever the vehicle is, we drain and clean it there, so a visit to the main dealer doesn't come into it.
Still with your vehicle?
Leave the engine switched off.
If you have already driven the vehicle, stop somewhere safe, switch it off then keep it off. Cold, parked, going nowhere: that is the best place to be in. People fear this a lot more than they need to.
Across Gloucestershire and in Shortwood: call-out fuel draining, at home or on the forecourt or at the kerbside.
