Borrowell: Put Petrol in a Diesel Car?
Petrol in Diesel drains and flushes misfuelled cars where they are, on the forecourt, at the roadside or on a drive, across Borrowell and the remainder of Warwickshire. The first thing to do is not to turn on the engine. While your engine has not yet been started and the fuel is still in your tank, a tank drain is almost always all it needs, and the following few minutes determine that, not how much went in. Our engineers shall show you what the next stage is. Phone — it comes before everything else.
Petrol in a diesel: what to try next
- Never fire it up. Started all the same? Then never trust it. Diesel in a petrol motor normally can't run, and so the motorist stops and the wear stops with them. Petrol in a diesel? It starts. It ticks over. It drives off happily, for several miles. Most people get that reversed. It is not okay — your fuel system is wearing down every mile you do.
- Turning the ignition on usually primes your system, and priming is what moves petrol out of your tank and into your pump and injectors. Those are the parts diesel keeps lubricated on its way through, before it combusts. Petrol does the burning and none of the lubricating. Leave the ignition alone.
- That advice supposes a diesel fuel system accepts petrol by percentage. It does not. Tip diesel on top and nothing at all is removed; what you end with is a fuller tank of the same blend. And no, the type makes no difference — super unleaded is still petrol.
- A vehicle that has not moved is the easiest one to sort, so wait where you are if you sensibly can. Pulled up on the verge on St Nicholas Avenue? Hazards on, then leave the car there. A tricky location works for us better than a started motor.
- Find out where you are before calling. A postcode that starts CV8 1, and the name of whatever is nearest to you. Otherwise the technician circles rather than turning up.
- Three facts shape the whole call-out: the liquid you put in, the ballpark volume involved, plus whether it has been turning since. The line is 0333 366 0103.
How many miles you travelled is what our engineers ask about, not how long your vehicle has been stood — and here's why. Diesel has two roles on its way through an engine: it ignites, and before burning it protects its high-pressure pump and those injectors. Petrol manages the first only. So a fast top-up on the road in, the penny dropping around eleven, and a diesel Renault Megane standing at Kenilworth since quarter past eight shows those few miles were done with your pump labouring on a fuel drained of much of its protection. Call us then leave the vehicle precisely where it sits.
The complicated part is the bay, not the fuel. Vehicles either side of you, a trolley shelter behind, and now and then a height barrier on the way in that determines whether a technician can get to you at all — so when you phone from a car park like the one at Sainsbury's, say how much space there's around you and which way round the vehicle is. Those our technicians visit regularly. Should there be no space to work beside your diesel Nissan Qashqai, it gets rolled with the engine off, and not out of pedantry over a couple of seconds of running: priming occurs at every start, more of the mix exits that tank for the pump, and two shunts into a nicer space have quietly made a worse job of what was merely a vehicle sitting still.
Put diesel in a petrol motor and mostly it won't run, and so the driver stops there and the wear stops with them. Swap it — petrol into a diesel — and the engine fires up, idles and drives off as though nothing had happened, whilst the high-pressure pump works without the protection the fuel is supposed to be providing. That's the trap, and it's why the diesel Audi A4 will have seemed completely usual coming back from St John's Primary School and Nursery. They do. From behind the wheel there is nothing to caution you about, and so nothing alerts you. Call us with roughly how far you went, and how hard; the second answer matters more than the first.
It will start. It will drive off quite happily. That's the problem, since a diesel on a weakened tank runs usually whilst wearing the components its fuel should be lubricating. So no, don't try the drive home from The Gauntlet — leave the Ford Focus and ring us.
Off the forecourt, receipt read, a couple of hundred yards, left near Kenilworth Cemetery. For a diesel Peugeot 3008 whose engine has turned, that is about the best version there is. Call us, then let it stand with the ignition alone. Short helps, really — 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 fuel lines get flushed and not just your tank cleared.
Forecourt draining for petrol in a diesel
The job begins at a forecourt, typically. Regularly the work finishes there too. The drain normally gets done on the spot. Still on the forecourt at Esso? Given the station's consent, that's a spot our engineers work, and regularly.
A forecourt is the only location it is spotted before your engine has run. Anywhere else — a car park, a driveway, a lay-by — the vehicle was fired up and moved to get there, which means fuel was drawn from the tank, through the filter then into the high-pressure pump. That is not a calamity, and we can still put it right where it sits. It does mean the lines and your filter need flushing as well as your tank, and that's determined by the few seconds between reading the till receipt and reaching for the key.
Staff will normally chip in pushing it clear of the pump, which lets the next customer get through. Accept the help. Four vehicle lengths isn't worth a restart.
Can our engineers reach your corner of Borrowell?
Being a residential suburb, Borrowell gets a frequent visit, and the places nearby come with it on the same trip: St Johns and Kenilworth, Abbey End and Abbey Fields, Whitemoor.
Not on this list? That tells you nothing. The places above are only the closest few, and most places in Warwickshire have a page of their own somewhere on the site. Contact us and check rather than presuming — borders particularly, and anywhere a satnav can misread.
The area this page covers is on the map. The vehicle doesn't need to come to us. Our technicians work over the lot — roadside, forecourts, driveways, car parks.
Borrowell: broken down wherever you parked
The chance to pull over anywhere sensible does not come to everybody. If you worked it out after setting off and finished up along the verge beside Queen's Road, or in a lay-by somewhere with the hazard lights on, that is a normal call for us instead of an unusual one.
Out of your car if it's not safe to wait inside, by it if it is. Never start it up to get to a safer place. It'll go — a diesel on petrol generally obliges — and each mile of obliging pulls the blend deeper into the fuel system. We will bring the van to a difficult location without any fuss, and for your car that is a lot better than carrying on.
Already run it? Petrol in a diesel over a few miles
This is where the M40 counts, under 10 miles away from Borrowell. Lost power, a lumpy idle, smoke: those are the symptoms when they come, rather than a tidy stop — and a misfuelled diesel will frequently take you onto it and some distance along before anything feels wrong at all.
Pull off at the first sensible junction, turn off, and don't start the car to move it. It affects what our technicians bring, so mention it when you call: on a longer run — anything close to the under 10 miles to the nearest city — take it the petrol has been through the filter, your pump and the fuel injectors.
A bit about Borrowell
Borrowell is a suburban area in Warwickshire, situated approximately 5.8 miles from Coventry and 84.4 miles from London. Borrowell sits at an elevation of around 88 metres, in a gently sloping landscape near the towns of Kenilworth and Abbey End. Borrowell has a population of around 5362 people, predominantly living in semi-detached housing. Borrowell is close to the neighbourhood of St Johns, sharing some local amenities and services.
What follows when we get to you around Borrowell
- Our technicians check what went in, how much, and whether your engine has run. The replies change the work, which is why we ask before pricing.
- Your tank is cleared completely.
- Fuel lines are rinsed through and the fuel filter cleared, leaving nothing in your system that started any of this.
- We pour fresh diesel in and prime the system.
- After it is turned on, we make sure it runs properly on clean diesel.
That has your car ready to drive away. We do all of it wherever the vehicle has stopped, which means it never needs to go to a workshop, and if it has been spotted early, it's very rare for there to be permanent damage.
AdBlue in your diesel tank by mistake, in Borrowell?
AdBlue instead of petrol? Then the opening rule is unchanged — your engine remains off — while the problem underneath it is a distinct one altogether. Petrol thins your diesel and strips the lubrication your fuel system relies on. AdBlue? Urea dissolved in water. Put that in with the diesel and you get rust instead, plus residue.
Both are ours. There is a separate Borrowell 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 fuel drain costs around Borrowell
What shifts the figure is listed below, as the job is not one job and our technicians cannot frankly put a single number on this page.
- Has it been run or driven? Nothing else counts for as much.
- The tank's capacity, set against how much of the wrong fuel went into it.
- Which was put in: petrol or AdBlue.
- Access: the vehicle's position, and whether working on it there's sensible for a van.
Tell us the vehicle, the quantity and if it has run, and you will get a firm answer instead of a range. Not time-critical, with the car at home and going nowhere? Then works.
Petrol in diesel queries from Borrowell drivers
Can you do a fuel drain at a petrol station in Borrowell?
A large portion of this work gets done there, so yes. Our technicians visit Texaco and the other forecourts nearby all the time, with the station's consent — tell us which one you are at when you ring and we'll tell you whether we can work there.
How much petrol in a diesel is too much?
Whether the engine has run counts a lot more, though the ratio matters too, rather than the litres. 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 blend been sucked right through, or has it not?
I drove the vehicle after putting petrol in my diesel. What now?
Stop safely. Off. Nothing after that. Driving shifts the problem along — out of the tank, into the pump and injectors. People fear it a good deal more than the recovery rate warrants, mind. The one genuinely valuable thing left to you isn't restarting the car.
Is a fuel drain going to void my warranty?
No. Carried out properly, clearing and purging 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 disagreement with one, which is another good reason to leave it turned off.
Could I put some two-stroke in and just drive?
What petrol has weakened is not replaced by two-stroke oil, which is an old fix for a separate fault. So no. That tank still has petrol in it afterwards, and your pump still has to put up with it.
Main dealers and petrol in a diesel
You don't need one. The car is drained and flushed wherever it is, with no need to take it to a dealership.
Still with your car?
Your engine stays off.
If you have already driven the vehicle, pull in somewhere safe, switch it off then leave it off. Cold, parked, going nowhere: that is the best position to be in. Drivers fear this far more than they need to.
Across Warwickshire and in Borrowell: on-site fuel draining, at home or on the forecourt or at the kerbside.
