If it has not been started, worry far less than you probably are. Petrol sitting in a diesel tank does nothing to your engine till something draws it through the system — the ignition priming the pump, your starter, or driving itself. So the honest answer to the first query anyone around Old Goole asks, "have I wrecked it?", is usually no. Petrol in Diesel is who to phone, with your engine left off, so it stays that way. Below, you will find what petrol really does inside a diesel, how far it may have got, and how to stop it happening to you a second time. ## The motor and petrol in a diesel: what goes on On its way through a motor, diesel has two jobs. Lubricating comes before burning; it does both. Built to extremely fine tolerances, the injectors and your pump depend on your diesel flowing through them to stop their surfaces wearing against one another. The second job petrol doesn't do at all, and the first it does poorly. A pump running on a petrol blend is wearing itself out, since petrol is thinner than diesel and strips out the protection the fuel system depends on. Petrol is also designed to resist igniting under compression — the reverse of what a diesel wants from its fuel — and that is where the rattling starts. Together, those leave the shape of the problem plain. The harm is done by circulation, not by contact. Petrol in a tank is a fuel issue. Once the pump has been running on that petrol, a mechanical problem has begun: anything shed by a pump that is wearing is carried onward to the fuel injectors with your fuel. ## Old Goole, petrol in a diesel: four situations, from mild to significant Fuelled, and never started: nothing beats it. Just your tank has petrol in it, so the job is draining the tank and rinsing the system where your car sits. This scenario can only really happen on a forecourt: anywhere else, your car got there by being driven. Your ignition turned on, or a brief start. Once primed, the system has pulled petrol from that tank up to the fuel filter and the fuel lines. Usually little more than emptying, flushing and seeing to the filter, and so still simple. A couple of miles driven, and your pump has spent each of them working on diluted fuel. Tank, lines, filter, then clean fuel run through the entire system: that is the work, and the way the car was driven matters as much as the miles. The school run to Marshlands Primary School is one thing. A run as far as Doncaster, under 25 miles away, is a very different task. So is any miles on the M62, under 3 miles from Old Goole, where your engine has been running hard the whole time. Clattering, a ragged idle, smoke, a throttle gone soft: driven till it complained. The motor is telling you your fuel is no longer behaving like diesel. Leave it wherever it has stopped: a lay-by, a quiet street, the verge on Manor Road. The drain and flush-through still go first, and they sort it out: when a car is pulled over soon, long-term damage is very uncommon. ## Petrol in a diesel stories Old Goole people hear False: topping up to full with diesel makes it fine. It does not. A bigger tank of the same mix is all it gives, because topping up removes nothing. The idea behind that guidance — that diesel fuel systems tolerate petrol by percentage — is wrong. If anything, the opposite is true. Myth: "A newer diesel can cope with a bit of petrol." A modern diesel runs its fuel through more precise parts at higher pressure, which makes the lubrication count more, not less. Myth: "If it starts and drives, there's no damage done." This is the one that fools motorists. Feed diesel to a petrol engine and it generally won't run, so the driver stops — and the damage stops with them. Feed petrol to a diesel and it normally fires up, idles and pulls away as if nothing has happened — all the while its pump is wearing. Running isn't the same as fine. "A drop of two-stroke oil and drive it home" — a myth, borrowed from a fix from years ago, for a separate issue. That petrol is still inside that tank after that, and what it has weakened is not put back. If your engine has been run, part of the petrol sits in the filter and the lines, not the tank — and the next start sends it straight back through your pump. So the myth "drain the tank yourself and you are sorted" does not hold. Besides, petrol cleared into a can by the road is genuinely risky. ## How it happens: petrol in a diesel Carelessness is seldom the cause, and nobody means to do it. One way only, since of the nozzles: the narrower petrol one slips inside a diesel filler with almost no resistance, while the diesel one generally won't fit a petrol vehicle. That is how the forecourt makes it straightforward. It happens when habit and the vehicle stop matching. Hire cars, courtesy cars, and motors that are new to you. One petrol and one diesel on the drive of the same household. Your ordinary forecourt, its pumps suddenly in a different order. A train to catch, and a rushed fill on the way to Goole. The first fill-up in a diesel Volkswagen Golf after years of driving petrol is precisely the moment it takes place. With rain, a call coming in, or a car full of children to deal with, the hand just does what it has always done. ## How to prevent petrol in a diesel at your next fill-up around Old Goole - 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. - Plenty of cars state the fuel type inside the filler flap or on the cap, so check there on your first fill in any motor you don't know. - Good intentions do less than a sticker or a fob in a bright colour on your diesel's key when a home has one of each. So label it. - Before the nozzle comes off the petrol pump the first time you fill a hired or new car, say "diesel" aloud. Silly, perhaps, but it does the trick. - Thinking about something else is when this becomes an easy mistake to make, so tuck your phone away and keep your mind on the petrol pump. - Add-on devices are available for vehicles without one, and some diesels come with a filler that will not accept a petrol nozzle. Helpful — but a safety net at best, never a reason to stop checking the label. - The moment you notice, stop: less petrol inside your tank means a thinner mixture. What to do next doesn't change, though — still don't fire it up. ## Petrol already in a diesel around Old Goole? Begin here Then the order of things is short. Do not crank it, and don't turn your ignition on. The staff on the forecourt — whether at Esso itself or wherever you filled up — will usually help roll it clear of the petrol pump if you ask. Next, 0333 366 0103. We'll ask what got in, roughly how much, and if it has been run. Say so if it was AdBlue instead of petrol: it's a different fault, with its own page for Old Goole, since AdBlue brings corrosion and deposits rather than lost protection. ## Old Goole petrol in a diesel jobs: why one costs more than another There's no fair single quote for this, because the four scenarios above are four different jobs. The situation itself does most of the work of moving the cost. After that it is the proportion — how much petrol got in against how much that tank holds — and after that where the car is and whether a van can reach it safely. That's why we ask three questions before pricing rather than after: what went in, how much, and if it has run. Those answers are what turn a range into one firm number. ## About Old Goole, for a moment Old Goole is a suburban area situated on the riverside in the East Riding of Yorkshire, with a population of around 2191 people.
