Petrol in Diesel

Put Petrol in a Diesel Car in Greenfields? Don't Start It

Don't fire up your engine. While the petrol is still sitting in that tank and your engine has not yet run, a fuel drain is almost always all it needs — and that gets determined in the following few minutes, not by how much got in. Petrol in Diesel drains and cleans wrongly fuelled cars where they are, across Greenfields and the rest of Shropshire, on the forecourt, by the roadside or on a private drive. Ring us so we will tell you what comes next before you do anything else.

Your first five steps: petrol in a diesel

  • Feed a petrol engine diesel and it will generally refuse to run at all, so the person stops there and so does the wear. Feed a diesel petrol and the thing starts, it ticks over, it moves off — all right for a few miles. People have that backwards, which is the bit they get wrong about petrol in a diesel especially. So don't crank it. And if started, don't rely on it: the fuel system is wearing as you drive.
  • Turning your ignition on frequently primes your system, and priming is what moves petrol out of that tank then into your pump and injectors. Those are the parts diesel keeps greased on its way through, before it burns. Petrol handles the burning and none of the oiling. Leave your ignition off.
  • Topping up gets rid of nothing. It leaves you a bigger tank of the same blend, since a diesel fuel system doesn't cope with petrol by percentage in the way that advice suggests — so never tip diesel on top to thin it. Octane is irrelevant too: super unleaded is petrol.
  • Wait where you are if you reasonably can. A vehicle that has not moved is the simplest one to deal with, and we would much rather get to a difficult location than have it started. If you're stopped on the verge on Stuart Way, turn those hazards on and keep it there.
  • Before you ring, work out your location. Anything nearest to you with a name on it, plus a postcode starting TF9 3 — that's what determines whether our van arrives or circles.
  • Three details shape the entire call-out: the liquid you put in, the rough volume involved, plus whether anything has been turning since. The line is 0333 366 0103.

Quarter past eight. A quick refuel on the drive in. Around eleven it hits you, and by then the diesel Volkswagen Golf has waited at Prees for three hours. Call us then keep it where it sits. What is key is the drive in, because diesel both burns and — before that — greases your pump and your injectors, while petrol only ever ignites. Those couple of miles worked your pump on a fuel stripped of a great deal of its protection, and no amount of sitting in a car park puts any of that back. Hence the thing we ask about miles instead of hours sitting, and hence the advice to leave your keys where they are until our technicians get there.

The phone call our technicians like goes like this: diesel Renault Clio, a few litres of unleaded, run a couple of miles, now shut off outside Morrisons. What we're actually asking is how much fuel your pump has sucked — not how long ago it was.

Your diesel Peugeot 308 will have felt completely usual on the way back from Market Drayton Infant & Nursery School. They always do, and that is the snag with petrol in a diesel rather than the other way round. Put diesel in a petrol car and it usually won't run, so the driver stops and the harm stops with them. Put petrol in a diesel and it fires up, ticks over and moves off as though nothing has happened — meanwhile the high-pressure fuel pump works without the protection your fuel is supposed to be providing. Nothing warns you, because from the driver's seat there's nothing to alert you about. Phone us with approximately how far you drove and how hard you drove it; the second answer counts more than the first.

Hire car? Company car? Call them before us. Some contracts want the firm to authorise the work, and that's much faster dealt with up front than afterwards. Then ring us about the Kia Sportage, the diesel one, near Market Drayton Library. 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 establish on site. The reason for asking: harm from petrol in a diesel is a matter of proportion. A few litres in an almost empty tank make a far stronger mixture 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 mix, more rattling, more smoke, flatter throttle.

By now that tank is the least of that. Run a diesel and the mix goes into the filter, into the fuel lines, into the pump, into its rail — and none of that leaves with your tank contents. A diesel Volvo XC60 that made it by Indoor market needs its system cleared. Clearing is not the same thing.

Mobile fuel drain van at a diesel car in Greenfields

Pump-side draining for petrol in a diesel

Much of this job starts at the pump, meaning a big portion of it gets finished at one. Our technicians work on station forecourts all the time, with the owner's permission, and so if you are still at Morrisons that's typically where this drain takes place.

Before your motor has started — a forecourt is the only location this gets spotted. Our engineers can still deal with it where it is, even away from the pumps. In a car park, on a drive or in a lay-by, the car has been fired up and moved there, and that sucked fuel through your filter then into your high-pressure pump, all the way from that tank. None of that is a catastrophe, though the flush then has to go past the tank to the lines and the filter, and the few seconds between reading your receipt and reaching for the keys are what decide that.

The attendants will normally offer to roll it clear of the petrol pump so the next motorist can get past. That is worth doing. Cranking it just to shift four vehicle lengths is not.

Coverage around Greenfields

These same journeys take us to Market Drayton, Little Drayton, Longslow, Spoonley and Longford Turning besides Greenfields, which is a residential suburb.

Not on that list? It means nothing. The places above are simply the closest few, and nearly all towns around Shropshire have a page of their own somewhere on our site. Phone and enquire rather than guessing, above all where you are on the border or somewhere your phone struggles with.

The map shows the ground this page covers. The vehicle does not need to come to us. We operate throughout every bit of that — roadside, forecourts, driveways, car parks.

Stranded on the roadside anywhere in Greenfields?

Not everybody gets the chance to pull in somewhere safe. Hazards flashing in a lay-by somewhere, or stopped on the verge of Tudor Close because you noticed after setting off — we take that call often enough that it is the normal kind.

Fine right there? Sit beside it. Not fine? Climb out and clear of it. It will frequently oblige. A diesel running on petrol limps along quite willingly, and that's the catch: start it up to reach somewhere handier and the mix goes further into the system with every mile driven. Pressing on causes your car far more harm than a technician driving out to a difficult place, and that is no problem for us.

Run it already? Pull over, and read below

under 10 miles out of Greenfields, the M6 is what counts now. Some way along, and onto it in the first place: a misfilled diesel will frequently manage both before anything seems wrong. What you get then is rarely a clean stop. Power falls away, your idle gets lumpy, and there may be smoke.

Pull off at the next sensible junction, switch off, and don't restart the vehicle to reposition. On a longer drive — anything near the under 25 miles to the closest city — assume the contamination has been through the fuel filter, the pump and the fuel injectors, and mention it when you ring. It changes what our engineers bring.

Greenfields itself

Greenfields is a suburban area in Shropshire, situated inland at an elevation of around 90 metres, with detached housing being the predominant type of accommodation. Greenfields lies approximately 15 miles from Stoke-on-Trent and is close to nearby places such as Market Drayton, Little Drayton, and Longslow. Greenfields has a population of around 3308 people and is located in the West Midlands region, about 139 miles northwest of London.

The job around Greenfields, step by step

  • The replies shape the work, which is why our engineers ask before quoting: what got in, how much of that, and if the motor has run.
  • The tainted mixture is pulled out of your tank.
  • Fuel lines are cleaned through and the fuel filter cleaned, leaving nothing in the system that caused any of this.
  • The fuel system gets primed, on new diesel.
  • Our technicians start the car and confirm it runs correctly on fresh diesel.

From that point, you're ready to set off. All of this is done where the car is, so it never needs to go to a workshop, and when it has been noticed soon, long-term damage is very unusual.

AdBlue in a diesel tank around Greenfields is a separate problem

The issue is not the same, though the opening step is — do not crank it — if what was put in was AdBlue rather than petrol. Weakened diesel, and no lubrication left for your fuel system that depends on it. That is petrol. Rust and build-up are what a diesel tank gets instead, as AdBlue is urea dissolved in water.

Frequently the more serious of the two, AdBlue — and the details lives on its own Greenfields page. Both are ours to handle.

Budgeting for a petrol-in-diesel fuel drain in Greenfields

Our technicians cannot put one price on this page honestly, because the job isn't one job. What moves it:

  • Has it been run or driven? Nothing else counts for as much.
  • Wrong fuel in, against what that tank holds — that ratio.
  • Which was put in: unleaded or AdBlue.
  • Where is it? And can a technician reach it and work there sensibly?

Tell us your car, the quantity and if it has run, and you will get a firm answer rather than a range. For the car at home that's going nowhere and is not time-critical, works too.

Greenfields drivers ask us these about petrol in diesel

I am on a forecourt in Greenfields. Can you drain the vehicle on the spot?

Much of what our engineers do takes place nowhere else. So yes. Routinely, provided the site agrees: Shell, plus every other forecourt nearby. Say on the phone where exactly you have stopped. Whether our engineers can work in that location is something our engineers answer on the spot.

Is there a sensible amount of petrol in a diesel?

Proportion decides it rather than litres — and more than either, whether your engine has run. Five litres in a nearly empty tank is a distinct case from five in a full one — but either way, the thing that determines how much work is required is whether that mixture has been sucked through the fuel system.

I drove the vehicle after putting petrol in my diesel. What next?

Switch off somewhere sensible, and keep it that way after you stop. Driving moves the problem along — out of the tank, into your pump and injectors. People fear it a good deal more than the recovery rate warrants, mind. The one truly helpful thing left to you isn't restarting it.

Will a fuel drain void my warranty?

No. Carried out correctly, clearing and purging is no modification 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 it switched off.

Could I put some two-stroke in and just drive?

Two-stroke oil solves a different issue, and an old one at that. Nothing it does puts back what petrol diluted. No. Petrol remains in that tank later on, whatever else goes in, and your pump gets no break from it.

Do I need a main dealer for petrol in a diesel?

There's no need to bring it to a main dealer, because our engineers drain and flush the vehicle wherever it is.

You, and your vehicle, still together?

The engine remains off.

Switch it off somewhere safe then leave it off, if you have already driven it. Cold, parked, going nowhere: that is the best place to be in. People fear this a lot more than they need to.

Across Shropshire and in Greenfields: on-site fuel draining, at home or on the forecourt or at the kerbside.
