Petrol in a Diesel Car in Linton Unstarted? Then less anxious than you probably are. Everyone in Linton begins with "have I ruined it?", and the fair answer is usually no: petrol resting in that tank of any diesel remains harmless till priming, cranking or driving draws it into your fuel system. To leave the vehicle that way, call Petrol in Diesel and leave the engine alone. The rest of this page explains what petrol really does to a diesel, how to judge how far it has got, and how to make sure it doesn't happen to you again. ## The motor and petrol in a diesel: what goes on Diesel does two jobs on its way through an engine. It lubricates first, and after that does it burn. The high-pressure fuel pump and the injectors are built to extremely fine tolerances, and the diesel passing through them is what stops those surfaces from wearing down against one another. Badly at the first, not at all at the second: that's petrol. It's runnier than diesel and takes away the protection your fuel system hinges on, and so a pump running on a petrol mix 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. The shape of the problem is clear when you put those together. The damage is done by movement, not by contact. Petrol in a tank is a fuel problem. Whatever a worn pump sheds goes on, carried by the fuel, into the injectors downstream, which is why a pump that has been working on the petrol is where a mechanical problem starts. ## Four situations we see around Linton: how bad is petrol in a diesel? Fuelled up, never started. The best case there can be. At a forecourt, and truly only there, the petrol is still confined to the tank — because everywhere else the vehicle was driven to get to it. The job is emptying and flushing on the spot. Your ignition turned on, or a brief start. Once primed, the fuel system has drawn petrol out of your tank up to your filter and the fuel lines. That is generally still a simple job — a drain, a flush, and the filter seen to. Those few miles driven were your pump running on fuel diluted by petrol throughout. The work is the tank, the fuel lines, the filter and clean fuel through the whole system, and how hard the vehicle was driven matters as much as how far. On the school run to Linton Primary School, the mileage is short. Driving as far as Lichfield, under 15 miles away, makes a very different job — as does any distance on the M42, under 5 miles from Linton, with your engine running hard all the way. It protested, and only then stopped: smoke, rattling, a throttle gone soft, an idle gone ragged. That is your motor telling you its fuel has stopped behaving like diesel. Leave it where it stops: a lay-by, a side street, the verge on Winchester Drive. What comes first is still the drain and flush-through, and that sorts it out, with long-term damage very unusual when a car is stopped quickly. ## What Linton motorists get told about petrol in a diesel — and the stories in it False: topping up to full with diesel makes it fine. It doesn't. A bigger tank of the same mix is all it gives, since topping up removes nothing. The idea behind that advice — that diesel fuel systems accept petrol by percentage — is wrong. "Newer diesels can handle a little petrol" — a myth, and nearer the reverse. Finer parts and higher pressure are how a modern diesel runs its fuel, and that makes the protection count 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 usually stops, because it will not run, and the damage stops with them. Feed petrol to a diesel and it usually starts, ticks over and drives away as if nothing has happened — all the while its pump is wearing. Being able to run isn't the same as being fine. "A drop of two-stroke oil and drive it home" — a myth, taken from a fix from years ago, for a different issue. That petrol is still in that tank after that, and what it has diluted is not put back. The next start draws petrol back round the pump out of the fuel lines and your filter, where some of it sits once your engine has been run. That's why draining your tank yourself does not leave you sorted — a myth. On top of that, petrol emptied into a can by the road is genuinely dangerous. ## Why petrol in a diesel occurs so easily On purpose? Never. Through carelessness? Rarely, if ever. A diesel nozzle mostly will not go into a petrol motor, but the narrower petrol nozzle goes into the filler of a diesel nearly without resistance — so forecourts make this one error straightforward, and just in one direction. Routine and the car getting out of step is when it happens. A car that is new to you — hired, on loan as a courtesy car, or just bought. A household with one petrol and one diesel on the driveway. A familiar forecourt with the pumps in a different order. Filling up in a hurry on the way to Burton-On-Trent, with a train to catch. A new-to-you diesel Volkswagen Passat, its first fuelling, and a motorist used to petrol: precisely when it takes place. Add rain, a phone call or a back seat full of children, and your hand repeats what it has always done. ## Next time you fill up in Linton: avoiding petrol in a diesel - Not every forecourt in the UK keeps to green for unleaded and black for diesel, though most generally do. Check the petrol pump's label; the colour is just a hint. - The first fill in a strange motor is the time to check the filler flap — on it, or on the cap, many cars state the fuel to use. - Mark your key. In a house with one of each, a coloured fob or a sticker on your diesel's key does more than any amount of intending to remember. - Before the nozzle leaves the pump the first time you fill a hired or new motor, say "diesel" aloud. Daft, perhaps, yet it does the trick. - Whilst you're thinking about something else, this is an easy mistake to make — so put the phone away. - Add-on devices exist for motors without one, and some diesels are built with a filler that won't accept a petrol nozzle. Useful — but a safety net only, never a reason to stop checking the label. - Noticing it halfway? Stop at once. A weaker mix results from less petrol in your tank, but the next stage stays the same: do not start the car. ## Linton: already put petrol in a diesel? Then, there is only a short order of things. Starting it is out, and so is switching on your ignition. Still on the forecourt, at Sainsbury's or anywhere else? Ask the staff to help you push it away from the pump. What was put in, roughly how much, and if it's run: tell us those when you ring 0333 366 0103. If it was AdBlue instead of petrol, say so. That is a different problem — corrosion and deposits instead of lost protection — and it has its own page for Linton. ## What makes one Linton petrol in a diesel task cost more than the next Four separate tasks lie behind the four situations above — which is why there is no fair single price. Mostly, the cost moves with which situation you are in. Beyond that it is the share — how much petrol went in against how much that tank takes — and after that where your car is and whether a technician can get to it safely. Three queries come first, before quoting, instead of after — what was put in, how much, has it run — and this is the reason. A range becomes a straight figure when the replies are in. ## About Linton, briefly Linton is a village in Derbyshire, situated inland at an elevation of 119 metres, with Linton being close to several nearby places including Linton Heath and Coton Park.

A forecourt, a supermarket car park, a lay-by or your own driveway are all spots our engineers work, and the car does not need to come to us. ## In Linton and still at the pump? Nothing beats it: that's where you now are. Keep it off. Ring.
