Far less than you probably are, provided it hasn't been started. "Have I ruined it?" is the first thing anyone in Ixworth asks, and the truthful answer is usually no, because petrol resting in a diesel tank hurts nothing till it's dragged through your fuel system — by ignition priming, by your starter, or by being driven. Petrol in Diesel is who to call, with the engine kept off, so it remains that way. Further down, you will find what petrol actually does inside a diesel, how far it might have gone, and how to stop it happening to you a second time. ## The motor and petrol in a diesel: what happens Diesel does two jobs on its way through a motor. It protects first, and after that does it burn. What keeps the surfaces inside your high-pressure pump and the fuel injectors from wearing against one another is your diesel passing through them — they're built to extremely fine gaps. Of these two jobs, petrol handles the first poorly and the second never. It is runnier than diesel and takes away the protection the system hinges on, so a pump running on a petrol blend is a pump wearing itself. And petrol is designed to resist igniting under compression, which is the reverse of what a diesel needs from its fuel. That is where the knocking comes from. Together, those make the shape of the issue clear. Not contact but circulation is what causes the damage. Any tank with petrol in it is a fuel issue. The beginning of a mechanical problem is a pump that has been working on that petrol — and whatever a worn pump sheds travels on with your fuel to the fuel injectors beyond it. ## Four situations our technicians see around Ixworth: how serious is petrol in a diesel? Filled but not once started — as good as it gets. On a forecourt, and truly only there, the petrol is still confined to that tank — since anywhere else your car was driven to reach it. The job is draining and rinsing on the spot. Your ignition turned on, or a short start. Petrol has come out of your tank and got to the filter and your lines, since your system has been bled. That's normally still a straightforward task — a drain, a flush, and your filter seen to. Driven a few miles. Now your pump has spent those miles labouring on thinned fuel. How hard your car was driven matters as much as how far, and this work covers that tank, the fuel lines, your filter and clean fuel through the entire system. On the school run to Ixworth Church of England Primary School, the mileage is small. Getting as far as Ely, under 50 miles away, makes a very different job — as does any mileage on the M11, under 50 miles from Ixworth, with your engine labouring hard all the way. It complained, and only then stopped: smoke, knocking, a throttle gone soft, an idle gone lumpy. The motor is telling you the fuel is no longer behaving like diesel. Pull up where you are — on the verge on Crown Lane, at the kerb, down a side road — and do not move it again. Lasting damage is very uncommon if a vehicle is pulled over soon, and the fuel drain and flush-through that still come first sort it out. ## Ixworth motorists and the petrol in a diesel myths they hear Myth: "Fill it the rest of the way with diesel and it'll be fine." It will not. Nothing is removed when you top up — the tank just carries more of the same blend. Percentage is not how a diesel fuel system tolerates petrol, whatever that advice supposes. Not so: a newer diesel copes with a bit of petrol. Rather, the opposite. At higher pressure, through smaller parts: that is how a newer diesel handles its fuel, and so the protection matters more, not less. This is the one that catches motorists. Myth: "If it starts and drives, there is no harm done." The driver of a petrol engine fed diesel normally stops, since it will not run, and the harm stops there. A diesel fed petrol usually starts, ticks over and drives away as if nothing has happened, while the pump grinds. Running is not the same as fine. Not so: a two-stroke additive lets you to drive home. It was an old fix, supposed for another issue. What petrol has thinned stays weakened, and the petrol stays inside the tank regardless. Myth: "Drain the tank yourself and you're sorted." Once the motor has been run, some of that petrol is no longer inside your tank: it's in your filter and the lines, and it goes straight back through your pump on the next start. Clearing petrol into a can at the roadside is also truly hazardous. ## Why petrol in a diesel takes place at all It is seldom carelessness, and no one does it on purpose. A diesel nozzle generally won't go into a petrol vehicle, but the slimmer petrol nozzle goes into the filler of a diesel nearly without resistance — so forecourts make this one mistake straightforward, and just in one direction. Habit and your car falling out of step is when it takes place. Courtesy car, hire car, or a vehicle that's brand new. Two cars on one driveway, one petrol, one diesel. A well-known forecourt with the pumps in a different order. Filling up in a rush on the way to Thurston, with a train to catch. Years of petrol cars behind you, a diesel Volkswagen Golf in front of you on the forecourt for its first tank — that is when. The hand repeats what it has always done once you add rain, a phone call or a back seat full of children. ## Next time you fill up in Ixworth: avoiding petrol in a diesel - Not every forecourt in the UK keeps to green for unleaded and black for diesel, even if most generally do. Read the pump's label; the colour is just a clue. - In a car you don't know, look inside the flap over the filler or at the cap before the first fill: many vehicles state the fuel type there. - Good intentions do less than a sticker or a fob in a bright colour on the diesel's key if a home has one of each. So label it. - "Diesel", aloud, before you pick up the nozzle — every time a new or hired car needs its first tank. It seems daft. It does the trick. - Thinking about something else is when this becomes an easy mistake to make, so put your phone away and keep your mind on the petrol pump. - Add-on devices are available for cars without one, and some diesels come with a filler that will not take a petrol nozzle. Useful — but a backstop at best, never a reason to stop checking the label. - The moment you notice, stop: less petrol inside that tank means a weaker blend. What to do next doesn't change, though — still do not fire it up. ## Ixworth: already put petrol in a diesel? Then the order of things is brief. Starting it is out, and so is switching on the ignition. The attendants on the forecourt — whether at Shell itself or wherever you filled up — will usually help roll it clear of the petrol pump if you ask. Ring 0333 366 0103 next, with three facts — the fuel, the approximate amount, and if it has run. AdBlue, not petrol? Then tell us. Corrosion and deposits, not lost lubrication, make it a different issue — Ixworth has a page all for it. ## What makes one Ixworth petrol in a diesel task cost more than the next The four scenarios above are four different jobs, so no single quote for this would be honest. Which of them you're in is mostly what moves your cost. After that it is the share — how much petrol went in against how much that tank holds — and then where the vehicle is and whether our van can reach it safely. What got in, how much, and if it has run — three questions we ask before costing, not after, for exactly that reason. The replies change a range into a straight figure. ## About Ixworth and its setting Ixworth is a village situated in the eastern part of Suffolk, near the River Ouse, with an elevation of around 38 metres.
