Put Petrol in a Diesel Car in Hole?
With the tank still carrying the petrol and the motor not yet started, nearly every job requires only a drain, so keep the engine off. That result is settled in the minutes straight after filling up, and not by the amount that went in. All over Hole and the remainder of Cumbria, Petrol in Diesel drains your car and flushes it where it sits, whether at a roadside, on a drive or at a forecourt. Call us before all else begins, and you will learn what comes from there.
Your next five minutes: petrol in a diesel
- Never fire it up — and don't believe it if it does start. This is the part most people get wrong about petrol in a diesel in particular. A petrol motor filled with diesel typically just cannot run, and so the motorist stops and the harm ends with them. A diesel filled with petrol typically starts, idles and moves off just fine for a few miles. It isn't fine. It's wearing your fuel system whenever you drive.
- Two tasks, diesel: it burns, and on the way through it keeps the high-pressure fuel pump and injectors oiled. Petrol only does the one. That is why the car's ignition stays off as well — turn it on and you usually prime the system, and that's petrol leaving the tank for just those components.
- That guidance assumes a diesel fuel system handles petrol by percentage. It will not. Add diesel on top and nothing at all is removed; what you have is a bigger tank of the same blend. And no, the type makes no difference — super unleaded is simply petrol.
- Stay put if it's sensible to. Hazards on, engine off, keep the vehicle. Wherever you have stopped — the verge on Meadow Close, anywhere — a difficult place for us trumps a started engine, and nothing is simpler for us to handle than a car that never shifted.
- Before you ring, gather your whereabouts. Anything nearest to you with a name on it, plus a postcode starting CA10 1 — that is what settles whether the technician turns up or circles.
- Phone 0333 366 0103. Anticipate three queries — what went in, approximately how many litres, and whether your car has been run. Those responses decide everything that comes after.
Petrol in a diesel Renault Megane, sitting outside Langwathby since this morning? The afternoon has cost you nothing — fuel in a tank is idle. It was the trip in that pushed thinned diesel through the pump. Ring us before you collect the car.
A diesel pump delivers fuel on demand, and a frantic morning dash asks for plenty — so three miles in the Audi A4 seems like nothing and isn't. Twenty to nine at the gates of Culgaith CofE School, already late, the receipt in your hand saying unleaded: hazards on, ignition off, phone us.
Out there fine, back gutless. If that was the run to Gillbank Wood, look at that tank. Diesel gets weakened by petrol, and thin fuel leaks past the fine clearances supposed to build injection pressure — so every further mile the diesel BMW 5 Series covered, the less pressure it held onto. Somewhere safe, turn off, phone us.
The pump sits before the injectors, and so whatever a worn one loses moves on with the fuel — which is why we are blunt about not driving on. Call us, then leave your diesel Vauxhall Astra where it is close to St Luke.
Rattling, a lumpy idle, white smoke, a throttle gone limp. That's a misfilled diesel Ford Kuga telling you what is wrong. Switch off where you have stopped, close to Skirwith Village Hall or anywhere else, and do not restart the vehicle to find a better place.
Can petrol be pumped from your diesel at a forecourt?
Pumps are where the job usually starts, and where a big portion of that ends. Still at the nearest petrol station? Then that is generally where it gets done. Station forecourts are routine for us, with the permission of the owner.
A forecourt is the only setting this is caught before your motor has run. The few seconds between seeing the receipt and going for your key determine how much needs flushing. Everywhere other than the forecourt — a car park, a drive, a lay-by — your car was switched on and moved to get there, so fuel was pulled from the tank, through the filter and into your high-pressure pump. That means the lines and your filter require flushing as well as that tank. It is not a disaster, and we can still deal with it where the car stands.
Roll it out of the way if the staff suggest it, and they normally will. The next motorist gets by the petrol pump, and that's worth doing. Firing the car to shift four vehicle lengths isn't.
Can we serve your end of Hole?
Hole is a residential suburb, so our vans go out to the town and to the places near it on those same journeys: Bradley, Ousby, Shire, Row and Crewgarth.
If yours isn't on this list it does not mean we never come — there are dedicated pages for the majority of places around Cumbria, and the ones named above are merely the immediate neighbours. Assuming is the mistake to avoid, above all on a boundary or anywhere your phone goes wrong. Ring us to enquire.
That map marks the ground the page covers. We operate roadside, on forecourts, on driveways and at car parks across all of it, and your car never needs to come to us.
Roadside call-outs in Hole
Not everyone gets the opportunity to pull over somewhere safe. A normal call for us and not a rare one: worked out after setting off, ended up along the verge on Ullesby Gardens or in a lay-by with your hazards on.
Okay there? Stay beside it. Not fine? Step out and clear of it. Every mile a diesel obliges you for on petrol draws that mix further into the fuel system — and oblige it often will, which is why your engine does not get restarted to limp somewhere better. However awkward the spot, it's no trouble for us to get to it, and that's far better for the car than carrying on.
Run it already? Pull in, then read below
Here is where the local M6 counts, under 10 miles from Hole. Lost power, an uneven idle, some smoke: those are the symptoms when they appear, instead of a tidy stop — and a misfilled diesel will often get you onto it and some distance along before anything seems wrong at all.
Take the first junction that's safe, stop there, and do not start the vehicle to move it. It alters what we bring, and so mention it when you phone: on a longer drive — anything approaching the under 25 miles to the closest city — take it the mixture has been through the fuel filter, the pump and the fuel injectors.
About Hole
Hole is a small suburban area in Cumbria, situated inland at an elevation of around 160 metres. Hole lies approximately 18.8 miles from Carlisle and 243.4 miles from London, within a rural landscape of rolling hills and scattered settlements. Hole is characterised by its predominantly detached housing stock, reflecting its development as a residential area. Hole remains a quiet community with a population of around 502 people.
The call-out in Hole, step by step
- We establish what got in, how much, and whether your engine has run. The replies shape the work, which is why we ask before giving a price.
- That tank gets emptied completely.
- Lines cleaned, filter cleaned. Whatever is left later on is not the thing that started the problem.
- We pour new diesel in and prime the system.
- It's fired up with new diesel in it, and we make sure that it is running properly.
That leaves the car ready to pull away. Lasting damage is very unusual when it has been noticed quickly, and because all of it is done where the car is, it never needs to be taken to a workshop.
AdBlue in your diesel tank instead, around Hole?
AdBlue rather than petrol? Then the first step is unchanged — the engine remains off — while the fault beneath it's a different one altogether. Petrol dilutes the diesel and strips the lubrication the system relies on. Rust and deposits are what a diesel tank gets instead, as AdBlue is urea in water.
Both are ours. There's a separate Hole page for AdBlue removal, with the detail on it — including the reasons it usually turns out to be the worse of the two.
What a petrol-in-diesel drain will cost around Hole
What moves the price is listed below, as the job is not one job and our engineers can't frankly put a single figure on this page.
- This is the key one: whether the engine has been run, or driven.
- Wrong fuel in, against what that tank holds — that ratio.
- Which got in: petrol or AdBlue.
- Where is it? And can a technician reach it and work there sensibly?
The car, the amount, whether it has run — give us those and the answer comes back straight and not as a range. Motor at home, going nowhere, nothing time-critical about it — is fine for that.
Things we get about petrol in diesel in Hole
I am on a forecourt in Hole. Can you drain the car on the spot?
Much of what we do takes place nowhere else. So yes. Our technicians work at another forecourt nearby and the other forecourts locally all the time, with the owner's agreement — tell us which one you're at when you call and we'll tell you whether we can work there.
A couple of litres of petrol in a diesel — too much?
Whether your motor has run counts a lot more, though the ratio counts too, rather than the litres. What determines how much work is needed is whether that blend has been sucked through the fuel system — since even though five litres in an almost empty tank is a different matter from five in a full one, either way that is the query.
I put petrol in my diesel and drove the vehicle. What next?
Somewhere safe, then stop, then switch off and leave it off. Driving is what takes the problem from the tank into the pump and injectors — but it is salvageable much more frequently than people fear, and the single most valuable thing you can do now is not restart the vehicle.
My warranty — does a fuel drain void it?
No. Carried out correctly, emptying and purging is no alteration at all, and the warranty from your manufacturer is untouched by it. A disagreement over a warranty is likelier to come from running a diesel on petrol — so leave it switched off.
Can I just add two-stroke oil and drive home?
What petrol has thinned isn't restored by two-stroke oil, which is an old workaround for a distinct problem. So no. Later? Still petrol in the tank, and a pump that has to put up with the stuff.
Do I need a main dealer for petrol in a diesel?
Wherever your car is, our technicians drain and clean it there, so a drive to the main dealer doesn't come into it.
You, and your car, still together?
Leave it shut off.
If you have already driven the vehicle, stop somewhere sensible, switch it off then leave it off. A parked, cold car is the best place to be in, and this is recoverable from much more often than drivers fear.
