Don't Start It If you have not turned on the engine yet, do not. A drain and nothing more is almost always what a car requires while the petrol is still sitting in your tank and the motor has not yet run, which is why it's the coming few minutes that matter, not how much got in. Petrol in Diesel travels to the vehicle wherever it has stopped in North Kilworth or the remainder of Leicestershire, on the forecourt, at the roadside or on a driveway, and drains and cleans it there. Call us and our team can tell you what follows next before you do anything else. ## What to do next about petrol in a diesel - Do not crank it — and never trust it if it runs. Here is the thing motorists have wrong about petrol in a diesel specifically. A petrol engine given diesel normally just will not run, so the motorist stops and the damage halts with them. A diesel filled with petrol normally starts, idles and drives away just fine for several miles. It is not all right. It is grinding that fuel system whenever you drive. - Diesel burns, and before it ignites it protects — that high-pressure fuel pump, those injectors. Petrol handles only the burning. So leave your ignition off as well: switching it on is commonly sufficient to prime the system, and priming moves petrol from that tank into precisely those parts. - Don't thin it. Diesel poured on top clears nothing, and so all you have is more of what was already there, because percentage isn't how a diesel fuel system copes with petrol. Super unleaded? Still petrol. The type makes no difference. - We would sooner drive to a difficult location than have it started — so if you reasonably can, stay put. Nothing is quicker to sort out than a car that hasn't shifted. On the verge on Wash Pit Lane, that means hazards on and keep it. - Have your location prepared before you call. A postcode starting LE17 6 and whatever is next to you with a label on it is the difference between the van turning up and the van circling. - Dial 0333 366 0103. Prepare for three things — what went in, about how much, and if the motor has been run. Your answers decide everything that happens next. The high-pressure pump did that morning drive working on a fluid that had shed a lot of the protection it is designed around. Diesel lubricates that pump, and the injectors with it, before any of the fuel burns; petrol does the burning and none of the oiling. So picture a diesel Volkswagen Golf, topped up at quarter past eight, taken in to work, and left standing at Rugby till the penny drops close to eleven. Three hours of sitting have changed nothing about it. The couple of miles before that altered a lot, which is why the thing our engineers ask is about miles not time. Phone. Keep it precisely where it sits. ## Draining petrol from your diesel at a forecourt A fair part of this work gets done at a forecourt, since that is where it often begins. If you're still at the forecourt at Esso, that's generally where this drain gets done — our technicians work on petrol station forecourts all the time, with the station's agreement. A filling station is the only location it can be halted before the engine has started. Fuel sucked out of the tank and through your filter, all the way to the high-pressure pump, is what happens when the engine is switched on and the car is moved to where it is now: the car park, the drive or the lay-by, anywhere other than the forecourt. So the flush includes the fuel filter and your lines together with that tank. That is still not a calamity, and our engineers put it right where the vehicle stands. What determines it is whether the key was turned in the seconds after the receipt was checked. Out from the petrol pump, the next customer can get by — so yes, let the staff help you push the vehicle. Worth it. Firing the car to move four car lengths isn't. ## Do our technicians reach your corner of North Kilworth? As a rural village, North Kilworth gets a regular call, while the areas nearby come along on that same trip: South Kilworth and Husbands Bosworth, Walton and Welford, Sulby. Our technicians still come. Those places above are just the closest neighbours, and a page exists for the majority of towns across Leicestershire, so an absence from the list is not an absence from the coverage. Ring us and ask instead of presuming, above all if you're on a boundary or anywhere your satnav misreads. The map is the ground this page includes. Every bit of that is territory our technicians cover: a kerbside, a forecourt, a drive, a car park. You don't drive the vehicle anywhere. Put diesel in a petrol vehicle and usually it won't run, so the person stops there and the harm stops with them. Swap it — petrol into a diesel — and the engine starts, ticks over and drives off as though nothing had happened, whilst the high-pressure fuel pump works without the protection your fuel is supposed to be supplying. That is the trap, and it's why the diesel Peugeot 308 will have felt perfectly usual coming back from St Andrew's Church of England Primary School, North Kilworth. They all do. From the driver's seat there's nothing to caution you about, so nothing alerts you. Phone with roughly how far you travelled, and how hard; the second answer matters more than the first. ## Stuck at the kerbside in North Kilworth Some people find no safe spot to pull over whatsoever. Set off, then twigged? Ended up along the verge on Green Lane, or sat in some lay-by with the hazards flashing? That's a common call here. Not a rare one. Out of the vehicle if it's not safe to wait inside, beside it if it is. Do not start it up to get to a better place. It'll go — a diesel on petrol usually obliges — and each mile of obliging drags the mixture deeper into the system. A van driving to a tricky location is no trouble for us, and it is much better for the vehicle than driving on. The parts that should be getting protected are wearing down instead, and your motor gives no sign of that: a diesel on a diluted tank starts and pulls away perfectly well. Risk the trip home from White Lion? Don't. Ring us then leave the Audi A4 where it stands. ## Already run it? Petrol in a diesel after a couple of miles Your M1 is the road which counts here, and sits under 5 miles from North Kilworth. A wrongly fuelled diesel will frequently get you onto it and some distance along before anything feels wrong, and the signs when they arrive are normally a loss of power, a rough idle and some smoke rather than a neat stop. Take the first junction that is sensible, pull up there, and don't start it to move it. It alters what our technicians bring, so tell us when you ring: on a longer trip — anything near the under 15 miles to the closest city — assume the mixture has been through your filter, your pump and the injectors. Out there happy, back sluggish. If that was the run to North Kilworth Sports Club, look at that tank. Diesel gets diluted by petrol, and thin fuel seeps past the fine clearances meant to build injection pressure — so every extra mile your diesel Ford Kuga covered, the less pressure it held onto. Somewhere sensible, switch off, phone us. ## North Kilworth itself North Kilworth is a rural village in Leicestershire, situated in the East Midlands region of England, with an elevation of around 144 metres. North Kilworth lies approximately 13 miles south of Leicester and 76.9 miles north of London, near the villages of South Kilworth and Husbands Bosworth. North Kilworth has a population of around 766 people, predominantly living in detached houses. ## What we do when our technicians get to you in North Kilworth - The answers change the work, which is why our engineers ask before giving a price: what was put in, how much of that, and whether your engine has run. - Our engineers clear that tank of the polluted fuel. - Lines cleaned, filter cleared. Whatever remains later is not the thing that created the problem. - Clean diesel goes in, and then the system gets primed. - When it is fired up, we check it runs properly on new diesel. That has it ready to set off. We do all of this wherever the car has come to a stop, which means it never needs to be taken to a garage, and if it has been spotted quickly, it is very uncommon for there to be permanent damage. ## AdBlue in a diesel tank around North Kilworth is a separate problem Don't fire it up: that first rule holds whether what got in was AdBlue or petrol. What changes is the problem itself. Petrol thins your diesel and strips the protection the system depends on. Rust and deposits are what a diesel tank ends up with instead, since AdBlue is urea in water. Often the more significant of the two, AdBlue — and the details lives on its own North Kilworth page. Both are ours to deal with. ## What a petrol-in-diesel fuel drain costs in North Kilworth Our technicians can't put one number on this page frankly, because this job is not one job. What moves it: - Started? Driven? Either answer matters more than anything else on this list. - How much of the wrong fuel got in, judged against how much the tank takes. - Whether it is petrol or AdBlue. - Whether a van can sensibly get to the car and work on it, which rests on where the vehicle is. Tell us what the car is, how much got in, and whether the motor has run. A straight answer comes back, not a range. If it is not urgent — the vehicle is at home and going nowhere — works too. Fixed and starting are not the same thing, and the difference is the circuit: we flush it, and take the filter off where there is a working one. Compare that with the certain tip you'll get — drain the vehicle, refill with new diesel. Half right. Do precisely that to a diesel Dacia Sandero near St Andrew's Church and it'll start, which is precisely why the advice sounds sensible. Then your engine sucks the petrol left behind in your filter, and in the feed lines, straight back through the pump, since draining a tank does nothing whatever about fuel that has already left it. Phone us instead. ## North Kilworth drivers ask us these about petrol in diesel ## Fuel drains on a North Kilworth petrol station forecourt A fair portion of this work gets done there, so yes. Tell us which one you are at when you phone and we'll tell you whether our engineers can work there. With the owner's permission we work at Inver and the other forecourts around town all the time. ## Is there a sensible quantity of petrol in a diesel? Ratio settles it instead of litres — and more than either, whether the engine has run. What settles how much work is needed is if that blend has been sucked through your fuel system — because although five litres in an almost empty tank is a distinct matter from five in a full one, either way that is the question. ## Petrol in my diesel, and I have driven the car Somewhere safe, then stop, then turn off and keep it off. Not restarting it is the single most helpful thing available to you now. Driving does shift the trouble out of that tank then into your pump and injectors, yes, and it remains fixable much more commonly than people assume. ## Is a fuel drain going to void my warranty? A drain then flush carried out properly is not an alteration and doesn't cancel a manufacturer's warranty. Another good reason to leave it turned off: running a diesel on petrol is the thing more likely to cause a disagreement with one. ## Two-stroke oil in your tank, and then home? No. It belongs to a separate fault from a bygone era, and petrol has weakened something no oil of that kind replaces. The tank still has petrol in it afterwards, and the pump still has to live with it. ## A main dealer for petrol in a diesel — essential? There's no need to bring it to a main dealer, since we drain and clean the car wherever it is. ## Still with your car? Shut off is how the car remains. Switch it off somewhere sensible and keep it off, if you have already driven it. A still, cold motor is the best position to be in, and this is recoverable from a lot more often than people expect. Throughout Leicestershire and around North Kilworth: on-site fuel draining, at home or on the forecourt or at the roadside.
