Brookside: Put Petrol in a Diesel Car?
If you have not turned on the engine as yet, do not. A drain and nothing more is nearly always what a car needs while the petrol is still sitting in that tank and the engine has not yet run, which is why it is the next few minutes that matter, not how much went in. Petrol in Diesel comes to your car wherever it has come to rest in Brookside or the remainder of Derbyshire, on the forecourt, at the roadside or on a driveway, and drains and flushes it there. Contact us before everything else begins, so you'll learn what follows from there.
What to try first about petrol in a diesel
- Give a petrol motor diesel and it will generally not run at all, so the person stops there and so does the damage. Feed a diesel petrol and the thing starts, it idles, it moves off — fine enough for a couple of miles. Most people have that backwards, which is the bit they get wrong about petrol in a diesel specifically. So don't start it. And if started, never depend on it: that fuel system is wearing while you drive.
- Switching the car's ignition on usually primes your system, and priming is what moves petrol out of your tank then into the pump and injectors. Those are the parts diesel keeps protected on its way through, before it burns. Petrol handles the burning and none of the protecting. Leave the car's ignition off.
- Do not water down it. Diesel added on top gets rid of nothing, and so all you have is more of what was already there, since percentage is not how a diesel fuel system accepts petrol. Super unleaded? Simply petrol. The grade makes no difference.
- A vehicle that hasn't shifted is the simplest one to sort out, and so wait where you are if you safely can. Stopped on the verge on Somersall Lane? Hazards on, and leave it there. A difficult spot suits us better than a started engine.
- Keep your location ready before you ring. A postcode that starts S40 3 and whatever is closest to you with a label on it is the difference between our van showing up and our van circling.
- What was put in, roughly how much, plus if the engine has fired — these three facts decide the entire job. Dial 0333 366 0103 then tell us.
Can petrol be taken from a diesel at the forecourt?
A big share of the work gets done at a forecourt, because that's where it usually begins. The drain typically takes place there and then. Still on the forecourt at Esso? Given the station's permission, that is a place our technicians work, and routinely.
At the forecourt, this is stopped with the motor never run, and no place else does it. The few seconds between seeing the receipt and going for the key determine how much requires cleaning. Everywhere other than a forecourt — a car park, a driveway, a lay-by — the vehicle was fired up and moved to get there, so fuel was sucked from that tank, through your filter then into the high-pressure pump. That means the fuel lines and the fuel filter need cleaning as well as that tank. It's not a disaster, and our technicians can still deal with it where the vehicle stands.
The staff will usually help you push the car out from the petrol pump so the next customer can get by. That is worth doing. Starting the car just for four vehicle lengths? Never.
If you've put petrol in your diesel Renault Megane around Brookside and you're now sat at Morrisons with a boot full of shopping, phone. Never crank it once more to leave that space. We will head your way, clear that tank, flush those fuel lines and put new diesel in so you can get home. A mile or so at light throttle draws hardly any fuel, which is why such jobs are often the straightforward jobs.
Every restart primes the lines and draws more petrol past the fuel filter and into your pump. So a misfilled diesel Peugeot 308 on the zig-zags outside Westfield Infant School is an inconvenience, whereas the same car started three more times to be helpful is a fuel system and not a tank. Someone will urge you to shift the car out of that gateway and sort it out later. Do not. Leave it, let them complain, and give us a call.
Simple job, this one — until someone takes it home. A diesel Nissan Qashqai left outside Maggie May's with petrol in your tank loses nothing by sitting there overnight, so park it and phone once it's light. Expect a query about that drive there, though. Short and cold is exactly where petrol battles to burn, and what will not burn can get past the piston rings then into the engine oil.
Off the forecourt, receipt read, a few hundred yards, parked by Storrs Road Methodist Church. For a diesel Dacia Duster whose engine has turned, that's about the best version there is. Ring us, and let the car stand with the ignition alone. Short assists, truly — but a start is a start and a drive is a drive, and the filter has had weakened fuel through it, and so has the pump. Which is why the lines get purged and not just the tank drained.
It got a few streets and stopped. The throttle went soft, the idle turned lumpy, and the diesel Vauxhall Astra is now sitting by Holymoorside & Walton North East Boundary Stone. That softness is your fuel failing to build pressure correctly rather than the motor packing up — and as there's no dashboard light for it, vehicles in that position normally get driven again before anybody rings. Don't. Switch it off and phone us.
Coverage in Brookside
The same journeys take us to Walton, Ashgate, Brampton, Loundsley Green and Nether Chanderhill as well as Brookside, which is a residential suburb.
We still come. The names above are just the immediate neighbours, and a page is there for most locations in Derbyshire, and so an absence from the list isn't an absence from our coverage. Ring us to ask rather than assuming, especially where you're on the boundary or somewhere the satnav struggles with.
The area this page spans is on this map. The lot is territory our technicians cover: a kerbside, a forecourt, a driveway, a car park. You don't bring the car anywhere.
Stranded by the kerbside somewhere around Brookside?
The opportunity to pull over somewhere sensible does not come to everyone. Hazards going at a lay-by somewhere, or pulled onto the verge on Somersall Close because you realised after setting off — we take that call so often that it's the ordinary kind.
Sit by the motor when it's safe to sit there, but clear of it if it's not. Don't fire it up to get to a safer spot. It will go — a diesel on petrol normally obliges — and each mile of obliging pulls the blend deeper into the fuel system. However inconvenient the location, it is no problem for us to come to it, and that's far better for the vehicle than pressing on.
A few miles on petrol in a diesel: what now?
Here is where the local M1 comes in — under 10 miles from Brookside. A misfilled diesel will frequently take you onto it and some way along before anything feels wrong, while the signs when they come are generally a loss of power, an uneven idle and smoke rather than a clean stop.
Take the first exit that's sensible, pull up there, and never restart it to move it. On a longer run — anything close to the under 15 miles to the closest city — assume the contamination has been through the filter, the pump and the injectors, and tell us when you call. It affects what our engineers bring.
A little about Brookside
Brookside is a suburban area in Derbyshire, situated on the riverside at an elevation of 118 metres, with detached housing being the predominant type of accommodation. Brookside lies approximately 10.6 miles from Sheffield and is close to nearby places such as Walton, Ashgate, and Brampton. Brookside has a population of around 2719 residents and is located in the East Midlands region, about 131.8 miles from London.
What comes next when our engineers arrive with you in Brookside
- The replies shape the work, which is why our technicians ask before giving a price: what went in, how much of it, and whether your engine has run.
- The tank is emptied of it.
- Fuel lines are purged through and your filter cleaned, leaving nothing in your system that caused any of this.
- The system gets bled, on new diesel.
- The engine is turned on and tested to be sure it runs smoothly on clean diesel.
Your car is then ready for you to drive away. There's no need to go to a garage at any point, since the work is all done where the car is, and when it is spotted quickly, lasting damage is very rare.
A different problem: AdBlue in a diesel tank around Brookside
AdBlue rather than petrol? Then the opening step is unchanged — your motor stays off — while the issue underneath it's a different one altogether. The lubrication a fuel system relies on is stripped away by petrol, which dilutes your diesel. Corrosion and build-up are what a diesel tank gets instead, since AdBlue is urea dissolved in water.
Both are ours. There is a separate Brookside page for AdBlue removal, with the details on it — including the reasons it often turns out to be the worse of the two.
How much is a petrol-in-diesel fuel drain in Brookside?
One number wouldn't be fair here, as this isn't one job. These are the things that shift it:
- Has it been started or driven? Nothing else matters for as much.
- How much of the wrong fuel was put in, set against how much your tank takes.
- The kind of liquid in the tank, petrol or AdBlue.
- Where the car is, and whether a technician can safely reach and work on it.
Tell us what your car is, how much went in, and whether your motor has run. A firm answer comes back, not a range. Vehicle at home, going nowhere, nothing pressing about it — is fine for that.
Questions we hear about petrol in diesel around Brookside
At a petrol station around Brookside, can you do a fuel drain there?
Much of what we do gets done nowhere else. So yes. Agreement from the site is the condition. Given that, a forecourt like Morrisons is somewhere we are often enough, along with the rest of them locally — so name yours on the phone and you will hear whether working there is possible.
How much petrol in a diesel is too much?
Litres are not the yardstick. Ratio is, and a lot more than either, it counts whether anything has been run. Five litres into a nearly dry tank is not five into a full one, no. But both land on the same question in the end: has that mix been sucked right through, or has it not?
I put petrol in my diesel and drove the car. What next?
Turn off somewhere safe, then keep it that way after you stop. Driving takes the problem along — out of your tank, into your pump and injectors. Drivers fear it a good deal more than the recovery rate warrants, mind. The one genuinely helpful thing left to you is not restarting the vehicle.
Fuel drains and manufacturer warranties
No. Carried out correctly, emptying and cleaning is no alteration at all, and the warranty from your manufacturer is untouched by it. Running a diesel on petrol is the thing more likely to cause a dispute with one, which is another good reason to leave the vehicle switched off.
Could I put some two-stroke in and just drive?
Two-stroke oil solves a distinct issue, and an old one at that. Nothing it does puts back what petrol diluted. No. Later? Still petrol in the tank, and a pump that has to live with the stuff.
A main dealer for petrol in a diesel — needed?
Not at all. Our engineers drain and clean the vehicle wherever it is, so there's no need to bring it to a main dealer.
You, and the vehicle, still together?
Keep the car turned off.
Already driven it? Then pull over somewhere sensible, switch off, and let the vehicle remain that way. Cold, still, going nowhere: that is the best place to be in. People fear this a lot more than they need to.
