Put Petrol in a Diesel Car in Lostock Junction? Don't Start It
With your tank still holding the petrol and the engine not yet run, almost every job requires only a drain, so leave your engine off. That result is determined in the minutes right after the fill-up, rather than by the amount that got in. Throughout Lostock Junction and the rest of Greater Manchester, Petrol in Diesel drains the car and flushes it where it sits, whether by a roadside, on a driveway or at a forecourt. Ring us before everything else starts, and you'll see what follows from there.
Your first five minutes: petrol in a diesel
- Don't start the vehicle — and do not rely on it when it starts. That is the part most people get wrong about petrol in a diesel in particular. A petrol engine given diesel usually just won't run, so the driver stops and the harm halts with them. A diesel filled with petrol usually starts, ticks over and moves off quite happily for several miles. It's not fine. It's wearing the fuel system whenever you drive.
- Two things, diesel: it burns, and on the way through it keeps that injection pump and injectors lubricated. Petrol only does the one. That is why the car's ignition is left off also — flick it on and you often prime that system, and that's petrol leaving your tank for exactly those parts.
- Don't thin it. Diesel added on top gets rid of nothing, and so all you have is more of what was already there, because percentage isn't how a diesel fuel system handles petrol. Super unleaded? Simply petrol. The type makes no difference.
- We would much rather travel to an awkward location than have it started — so if you reasonably can, sit tight. Nothing is simpler to sort out than a motor that hasn't moved. On the verge on Kilworth Drive, that means hazards on then keep the car.
- The van showing up instead of circling rests on two things: a postcode beginning BL6 4, and whatever is next to you with a sign on it. Get both prepared before you dial.
- What was put in, about how many litres, and if the engine has fired — these three facts shape your whole job. Phone 0333 366 0103 then tell us.
Can petrol be pumped out of your diesel at the forecourt?
Pumps are where the job mostly starts, and where a fair part of that ends. If you are still on the forecourt at Shell, that's normally where the drain happens — our technicians work on garage forecourts routinely, with the station's agreement.
Before the motor has started — a forecourt is the only location it gets stopped. Our technicians can still put it right where it is, even away from the pumps. In a car park, on a driveway or in a lay-by, the vehicle has been started and moved there, and that sucked fuel through the fuel filter and into the high-pressure fuel pump, all the way from your tank. None of that is a disaster, though the flush then has to go past the tank to the fuel lines and the filter, and the few seconds between seeing the till receipt and going for your key are what decide that.
The staff will normally help you roll the vehicle clear of the pump so the next motorist can get past. That is worth doing. Four vehicle lengths is not worth a start.
Diesel Renault Clio. A few litres of unleaded. Done a couple of miles. Turned off now, at The Co-operative Food. That's the call we like, since the question under it's about quantity through your pump instead of hours on the clock.
Three answers decide most of the work: what got in, about how much, and whether your engine has run since. We ask for them when we reach the vehicle in the car park outside Beaumont Arms. Then the polluted mix comes out of the tank, the lines are rinsed, and where your BMW 3 Series has a serviceable filter, it comes off. After new diesel is in and the fuel system primed, our engineers fire it up and check it runs smoothly before you pull away.
Why so direct about leaving the keys alone? Since the pump is ahead of the fuel injectors, and a worn one sends whatever it gives off onward with your fuel. Phone us. Leave the Peugeot 3008 by St Thomas & St John Lostock Parish Church.
Turn off where you have stopped, and do not restart it to find somewhere better — close to Chew Moor Methodist Church or anywhere at all. Knocking, a ragged idle, white smoke and a soft throttle are a misfuelled diesel Audi A3 telling you what's wrong.
That deadness is your fuel failing to build pressure correctly, not the motor packing up — and with no warning for it, motors in that position normally get driven once more before somebody rings. Please don't. A few streets is all it got: throttle gone dead, idle turned lumpy, and a diesel Vauxhall Astra now waiting by Christ Church Heaton Church of England. Turn the car off and call us.
Do we cover your end of Lostock Junction?
The same journeys bring us to Fernhill Gate, Chew Moor, Hunger Hill, Markland Hill and Deane along with Lostock Junction, which is a residential suburb.
Our engineers still come. The names above are only the closest neighbours, and a page exists for the majority of places around Greater Manchester, and so an absence from the list isn't an absence from the coverage. Presuming is the thing to avoid, above all on the border or anywhere a satnav gets lost. Contact us to ask.
The area the page includes sits on the map. Every bit of that is territory our engineers serve: a roadside, a forecourt, a private drive, a car park. You do not bring the vehicle anywhere.
Roadside stops in Lostock Junction
Not everyone gets the chance to pull over somewhere safe. A routine call for us instead of an odd one: worked out after setting off, ended up by the verge of Junction Road West or at a lay-by with the hazard lights on.
Sit with the car if it's safe to wait in it, yet out of the car if it's not. Don't restart it to reach a better location. It'll go — a diesel on petrol normally obliges — and each mile of obliging drags that blend deeper into the system. However inconvenient the location, it is no problem for us to come to it, and that's a lot better for the vehicle than pressing on.
Run it already? Pull in, then read this
Your M61 is the one that counts now, and runs under a mile from Lostock Junction. A wrongly fuelled diesel will often get you onto it and some distance along before anything seems wrong, while the symptoms when they arrive are typically a drop in power, an uneven idle and some smoke instead of a clean stop.
Take the first junction that's safe, pull up there, and do not restart it to move it. It affects what our technicians bring, and so say so when you call: on a longer run — anything close to the under 15 miles to the closest city — assume the contamination has been through your filter, your pump and your injectors.
Lostock Junction itself
Lostock Junction is a suburban area in Greater Manchester, situated near several lakes and waterways at an elevation of around 132 metres. Lostock Junction lies within commuting distance of Salford and other major urban centres in the North West, with nearby places including Fernhill Gate, Chew Moor, and Hunger Hill. Lostock Junction is characterised by its predominantly detached housing stock, reflecting its development as a residential area.
The call-out around Lostock Junction, step by step
- Our engineers ask first, price after. What went in? How much? Has your engine run? Those replies shape what the work actually is.
- Out comes the tainted fuel.
- Lines cleaned, filter cleaned. Whatever remains later isn't the thing that started the issue.
- New diesel goes in, and then your system gets bled.
- It's run with clean diesel in it, and our engineers check that it's running correctly.
The car is then ready for you to pull away. Permanent damage is very rare when it has been caught soon, and because all of it is done where the vehicle is, it never has to go to a workshop.
Lostock Junction AdBlue removal is a distinct job
AdBlue instead of petrol? Then the opening rule is unchanged — your engine stays off — whereas this fault underneath it is a separate one altogether. Petrol weakens the diesel and removes the lubrication the system depends on. Corrosion and build-up are what a diesel tank gets instead, as AdBlue is urea in water.
Our engineers deal with both, and AdBlue removal around Lostock Junction has its own page with the detail — including why it's usually the more serious of the two.
How much is a petrol-in-diesel fuel drain around Lostock Junction?
One figure wouldn't be honest here, because this is not one job. These are the things that shift it:
- Whether the engine has been started or driven. This is the main one.
- The tank's capacity, set against how much of the wrong fuel got into it.
- Whether it's unleaded or AdBlue.
- Where your car is, and if our van can sensibly get to and work on it.
The vehicle, the amount, whether it has run — give us those and the answer comes back straight instead of as a range. Not time-critical, with the car at home and going nowhere? Then does this job.
Petrol in diesel: frequent queries around Lostock Junction
I am on a forecourt in Lostock Junction. Can you drain the car here?
Yes — forecourts are where a large share of this takes place. Our technicians work at BP and the other forecourts nearby all the time, with the station's permission — tell us which one you are at when you call and we'll tell you whether we can work there.
How much petrol is too much for a diesel?
It hinges on the ratio rather than the litres, and a lot more on whether your motor has 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 mixture been pulled right through, or has it not?
I drove the vehicle after putting petrol in my diesel. What next?
Somewhere sensible, then stop, then turn off and keep it off. It is salvageable far more frequently than motorists fear, even though driving is what shifts the trouble from that tank into your pump and injectors — and the single most valuable thing you can do now is not restart it.
Is a fuel drain going to void my warranty?
A manufacturer's warranty survives a drain then flush done to a good standard, which is no change at all. An argument over a warranty is likelier to come from running a diesel on petrol — so leave it turned off.
Adding two-stroke oil, then driving home
What petrol has weakened is not replaced by two-stroke oil, which is an old workaround for a distinct fault. So no. Petrol stays 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?
No. Our technicians drain and flush the car wherever it is, so there is no need to take it to a franchised dealer.
Still with your vehicle?
Switched off is the way the car remains.
Switch it off somewhere safe and leave it off, if you have already driven it. This is recoverable from far more frequently than people expect, and a parked, cold vehicle is the best position to be in.
