Petrol in a Diesel Car in Hipsburn Far less than you probably are, if it has not been started. Petrol sitting in a diesel tank does nothing to your motor till something draws it through the system — the ignition priming your pump, your starter, or the drive on its own. So the honest answer to the first question everyone in Hipsburn asks, "have I ruined it?", is normally no. Leave the engine off then call Petrol in Diesel — that is how you keep it that way. What petrol actually does to a diesel, how to gauge how far it's travelled, and how to stop it from happening a second time: that is the rest of this page. ## Petrol in a diesel: what does it do to your engine? On its way through an engine, diesel does two tasks. Before it combusts, it protects — and then it combusts. The high-pressure pump and your injectors are built to extremely fine clearances, and the diesel passing through them is what stops those surfaces from wearing against each other. Petrol handles the first job badly and the second not at all. The knocking comes from petrol being made not to ignite when compressed, which is precisely the reverse of what a diesel needs. On top of that it is runnier than diesel, it strips out the lubrication the system hinges on, and any pump running on that mix is wearing itself. The shape of the trouble is clear once you put those together. The harm is done by movement, not by contact. All a tank with petrol in it amounts to is a fuel problem. The beginning of a mechanical one is a pump that has been labouring on that petrol — and whatever a worn pump sheds moves on with your fuel to the fuel injectors downstream. ## Hipsburn, petrol in a diesel: four cases, from mild to major Filled up, never started. The best case there is. Being on a forecourt is what makes this possible: elsewhere, the car has been driven there to begin with. With that petrol kept in the tank alone, it's drained and flushed on the spot, and nothing more is needed. Ignition on, or started for a second. Petrol has come out of the tank and got to the fuel filter and the fuel lines, since the system has been bled. Still usually simple: drain, flush, and the filter seen to. Driven a couple of miles. Now your pump has spent those miles working on weakened fuel. How hard the car was driven matters as much as how far, and the work covers the tank, your lines, your filter and clean fuel through the whole system. On the school run to Hipsburn Primary School, the distance is small. Driving as far as Newcastle upon Tyne, under 50 miles away, makes a very different job — as does any miles on the A167(M), under 50 miles from Hipsburn, with your engine working hard all the way. It complained, and only then stopped: smoke, rattling, a throttle gone soft, an idle gone ragged. The fuel is not behaving like diesel any more, and your motor is telling you. Leave it wherever it stops: a lay-by, a quiet street, the verge on South View. Lasting damage is very unusual if a car is stopped early, and the drain and flush-through that still go first take care of it. ## What Hipsburn motorists get told about petrol in a diesel — and the stories in it It will not be fine. The myth: "Fill it the rest of the way with diesel and it'll be." Nothing is removed by topping up — you are left with a fuller tank, still the same mix. Percentage is not how a diesel fuel system tolerates petrol, whatever that advice supposes. "Current diesels can handle a little petrol" — a myth, and nearer the reverse. At higher pressure, through smaller components: that's how a newer diesel handles its fuel, so the lubrication counts for more, not less. This is the one that catches motorists. Myth: "If it starts and drives, there's no harm done." The driver of a petrol engine fed diesel normally stops, since it will not run, and the harm stops there. While the pump wears, a diesel fed petrol normally starts, ticks over and drives away as if nothing has happened. Running isn't the same as fine. An outdated fix for a distinct issue lies behind this one. Myth: "Add some two-stroke oil and drive the vehicle home." The petrol is still inside the tank afterwards, and whatever it has weakened isn't put back. The next start sends petrol back round your pump out of your lines and your filter, where some of it ends up after the engine has run. That's why a DIY tank drain doesn't leave you sorted — a myth. Besides, petrol cleared into a can by the road is genuinely dangerous. ## How petrol ends up: petrol in a diesel No one does it on purpose, and it is rarely carelessness. The forecourt makes it easy: the petrol nozzle is the slimmer of the two, and it slips into a diesel filler with almost no resistance, while a diesel nozzle generally will not go into a petrol motor at all. So the mistake runs one way. The moment routine stops matching the car is the moment it occurs. A car that is new to you — a hire car, on loan as a courtesy car, or just bought. Two motors on one driveway, one petrol, one diesel. A forecourt you know, only with its pumps laid out differently. A train to catch, and a rushed fill on the way to Alnmouth. Exactly the moment it happens: after years of driving petrol, a driver fills a diesel Volkswagen Golf for the first time. Add a back seat full of kids, a phone call or rain, and habit wins. ## How to prevent petrol in a diesel at your next fill-up around Hipsburn - Read the pump, not the colour. In the UK unleaded handles are usually green and diesel black, but not on each forecourt. The label is what matters. - Plenty of cars state the fuel type inside the filler flap or on the cap, so check there on the first fill in a motor you do not know. - One of each in the household? Label the key to your diesel — a bright fob, a sticker — since meaning to remember isn't enough. - Say it before you lift it. On your first fill in a new or hired car, say "diesel" out loud before you lift the nozzle off the petrol pump. It seems daft and it works. - Put the phone away. This is an easy mistake to make whilst you're thinking about something else. - Add-on devices exist for vehicles without one, and some diesels are built with a filler that won't take a petrol nozzle. Useful — but a backstop only, never a reason to stop checking the label. - Noticing it halfway? Stop at once. A thinner blend follows from less petrol in your tank, but the next step stays the same: don't crank it. ## Petrol already in a diesel around Hipsburn? Begin here Short and simple, then, is the order of things. Do not crank it, and do not turn the ignition on. The attendants at the forecourt — whether at Shilbottle Coal Company itself or wherever you filled up — will usually help roll it clear of the pump if you ask. Next, 0333 366 0103. We'll ask what went in, roughly how much, and if it's been run. If it was AdBlue and not petrol, say so. That's a separate problem — corrosion and deposits and not lost lubrication — and it has its own page for Hipsburn. ## What makes one Hipsburn petrol in a diesel job cost more than the next There is no honest single quote for this, since the four scenarios above are four different tasks. Which of them you are in is chiefly what shifts your cost. Two things come after that: the petrol that was put in as a share of what the tank takes, then the spot the car is in and whether our van can reach it safely. Three questions come first, before any quote, instead of after — what went in, how much, has it run — and this is the reason. Given the answers, you get a straight figure rather than a range. ## About Hipsburn and where it is Hipsburn is a small coastal village in Northumberland, situated near the mouth of the Aln Estuary at an elevation of 23 metres.
