Less than you likely are, if it has not been started. Petrol sitting in a diesel tank does nothing to your engine until something pulls it through the system — your ignition priming the pump, the starter, or driving on its own. So the fair answer to the first query everyone in Pinvin asks, "have I ruined it?", is normally no. To keep the vehicle like that, phone Petrol in Diesel then leave your engine switched off. Below, you will find what petrol really does inside a diesel, how far it might have gone, and how to stop it happening to you again. ## The motor and petrol in a diesel: what happens Two jobs fall to diesel on its route round a motor. Lubricating comes before burning; it does both. Extremely fine tolerances go into the fuel injectors and the high-pressure pump, and just your diesel running through stops their surfaces grinding together. Petrol handles the first task poorly and the second not at all. Being less viscous than diesel, petrol strips out the lubrication a fuel system needs, so a pump on the mixture to wear itself. It is equally made to resist igniting under compression — the reverse of what a diesel needs — which is where you hear the rattling. Combined, those leave the shape of the trouble clear. Contact does not do the damage — movement does. A tank with petrol in it is a fuel fault. Whatever a worn pump sheds goes on, carried by your fuel, into the injectors further along, which is why a pump that has worked on that petrol is where a mechanical issue begins. ## How serious is petrol in a diesel? Four situations our engineers see in Pinvin Filled up, and never started: nothing beats it. That petrol is inside that tank and only the tank, and the task is a drain and a flush where your car sits. This is the one situation that can only truly occur at a forecourt, since anywhere else your car has been driven to get there. Ignition on, or started for a second. The system has been primed, so petrol has left that tank and reached the filter and your lines. Still usually straightforward: drain, flush, and the fuel filter sorted. The pump now spent a couple of miles on diluted fuel — that's what driving the vehicle meant. Tank, lines, filter, then clean fuel run through the entire circuit: that's the work, and the way the vehicle was driven counts as much as the mileage. Driving the kids to Pinvin CofE Academy is one kind of trip. Very different again: a run to Worcester, under 10 miles away, or some miles on the M5, under 10 miles from Pinvin, where your engine never stopped working hard. It protested, and only then stopped: smoke, knocking, a throttle gone soft, an idle gone uneven. What you are hearing is the motor reporting fuel that no longer acts like diesel. Whether it's the verge on Spion Kop, a lay-by or a side road, stop there and leave it. What goes first is still the fuel drain and flush-through, and that takes care of it, with permanent damage very unusual if a car is stopped soon. ## Stories Pinvin people hear about petrol in a diesel It will not be fine. The myth: "Fill it the rest of the way with diesel and it'll be." A fuller tank of the same mix is all you get, because topping up takes out nothing. Percentage isn't how a diesel fuel system copes with petrol, however much that guidance assumes. Myth: "A newer diesel can cope with a bit of petrol." If anything, the reverse. At higher pressure, through more precise components: that is how a current diesel moves its fuel, so the lubrication matters more, not less. This is the one that catches people. Myth: "If it starts and drives, there is no harm done." The driver of a petrol engine fed diesel usually has no choice but to stop, because it will not run, and the harm stops there. Feed petrol to a diesel and it usually fires up, idles and drives away as if nothing has happened — all the while its pump wears. Fine and running are not the same thing. Myth: a two-stroke additive lets you to drive home. It was an old workaround, supposed for another problem. That petrol is still in your tank afterwards, and what it has diluted is not put back. The next start sends petrol back round your pump from the fuel lines and the filter, where some of that ends up once the engine has been run. That is why draining your tank yourself does not leave you sorted — a myth. Draining petrol into a can at the roadside is also really hazardous. ## Why petrol in a diesel happens so easily It's rarely carelessness, and no one does it on purpose. The forecourt makes it simple: the petrol nozzle is the smaller of the two, and it slides into a diesel filler with almost no resistance, while a diesel nozzle generally will not go into a petrol car at all. So the error runs one way. Habit and the vehicle getting out of step is when it happens. A new motor, a hire car or a courtesy car. One petrol and one diesel on the driveway of the same household. A forecourt you know, but with its pumps laid out differently. Racing for a train outside Pershore and fuelling up en route. The first fill-up in a diesel Volkswagen Passat after years of driving petrol is exactly the moment it happens. With rain, a call coming in, or a car full of children to deal with, your hand just does what it always has. ## Next time you fill up around Pinvin: preventing petrol in a diesel - Not every forecourt in the UK follows green for unleaded and black for diesel, even if most usually do. Read the petrol pump's label; the colour is just a clue. - Many motors state the fuel inside your filler flap or on the cap, and so check there on your first fill in a car you do not know. - One of each in the house? Mark your key to your diesel — a bright fob, a sticker — since intending to remember is not enough. - Before the nozzle leaves the pump the first time you fuel a hired or new vehicle, say "diesel" aloud. Daft, yes, but it works. - Tuck the phone away. This is an easy mistake to make whilst you are thinking about something else. - A misfuel inhibitor helps, up to a point. Some diesels have a filler designed to reject a petrol nozzle, and add-on devices are available for cars without one. They are a backstop, not a reason to stop reading the petrol pump. - As soon as you notice, stop: less petrol in the tank means a weaker mixture. What to do next doesn't change, though — still do not fire it up. ## Put petrol in a diesel in Pinvin already? Short and simple, then, is the order of things. Starting it is out, and so is turning on the ignition. Still on the forecourt, at the nearest petrol station or anywhere else? Ask the staff to help you push it clear of the pump. Phone 0333 366 0103 next, with three answers — your fuel, the rough volume, and whether it's run. Corrosion and deposits form the trouble with AdBlue, where petrol means lost protection. So if it was AdBlue, say so — and read its own Pinvin page. ## Why one petrol in a diesel task around Pinvin costs more than another A fair single price doesn't exist here: four scenarios, four separate jobs. Which of them you're in is chiefly what moves the cost. Where your car is counts too, and whether a van can safely reach it, after the ratio of petrol to what that tank holds. Three questions come first, before quoting, instead of after — what got in, how much, has it run — and that is the reason. Those replies are what turn a range into one firm number. ## About Pinvin, briefly Pinvin is a village in Worcestershire, situated on the banks of the River Avon at an elevation of 32 metres.
