If it has not been started, worry far less than you likely are. Petrol sitting in a diesel tank does nothing to the motor till something draws it through the fuel system — your ignition priming the pump, your starter, or driving on its own. So the fair answer to the first query everyone around Lower Burgate asks, "have I ruined it?", is normally no. Petrol in Diesel is who to ring, with your engine left off, so it stays that way. Below, this page sets out what petrol really does inside a diesel, how far it might have gone, and how to stop it happening to you a second time. ## Inside the motor: what petrol in a diesel really does Passing through a motor, diesel does two things at once. It ignites, and before it burns it protects. What keeps the surfaces inside the high-pressure pump and the injectors from wearing down against one another is the diesel passing through them — they're made to extremely fine tolerances. The second task petrol doesn't do at all, and the first it does badly. The clattering comes from petrol being designed not to ignite when compressed, which is exactly the opposite of what a diesel needs. On top of that it is thinner than diesel, it strips away the lubrication your system hinges on, and any pump working on that mix is wearing itself. Taken together, they show the shape the trouble has. Not contact but movement is what causes the damage. Petrol in the tank is a fuel issue. Once the pump has been working on that petrol, a mechanical problem has started: anything shed by a pump that's grinding is carried onward to your injectors with the fuel. ## Four situations our technicians see in Lower Burgate: how serious is petrol in a diesel? Fuelled but never started — as good as it gets. Being at a forecourt is what makes this possible: elsewhere, the car has been driven there to begin with. With that petrol held inside that tank alone, it's cleared and rinsed right where it stands, and nothing more is needed. A brief spell of running, or merely the ignition on. Once primed, your system has drawn petrol out of the tank as far as the filter and the lines. Normally little more than clearing, flushing and sorting the filter, and so still straightforward. Driven a few miles. Now the pump has spent these miles running on thinned fuel. Distance is only half of that; how hard it was driven counts equally. Either way the work runs to the tank, the fuel lines, the fuel filter and fresh fuel through the whole system. The school run to Fordingbridge Junior School is one matter. Driving as far as Salisbury, under 10 miles away, makes a very different task — as does any distance on the M27, under 10 miles from Lower Burgate, with the motor running hard the whole time. It protested, and only then stopped: smoke, knocking, a throttle gone soft, an idle gone lumpy. The motor is telling you your fuel is no longer acting like diesel. Stop wherever you are — the verge on Salisbury Road, a lay-by, a side street — and leave it there. What comes first is still the fuel drain and flush-through, and that deals with it, with long-term damage very rare when a vehicle is pulled over quickly. ## Petrol in a diesel myths Lower Burgate people hear Myth: "Fill it the rest of the way with diesel and it will be fine." It will not. Nothing is removed when you top up — the tank simply holds more of the same mixture. That guidance assumes a diesel fuel system tolerates petrol by percentage. It does not. Myth: "A modern diesel can cope with a bit of petrol." If anything, the opposite. Smaller components and higher pressure are how a newer diesel runs its fuel, and that makes the lubrication count more, not less. Myth: "If it starts and drives, there is no damage done." This is the one that catches motorists. Diesel in a petrol motor usually means a motor that will not run: the motorist stops, and so does the damage. While your pump grinds, a diesel fed petrol normally starts, ticks over and drives away as if nothing has happened. Being able to run is not 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. It doesn't put back what petrol has thinned, and the petrol is still inside the tank later. Myth: "Drain your tank yourself and you're sorted." After your engine has run, some of the petrol is no longer in that tank: it is in the fuel filter and the fuel lines, and it goes straight back through the pump on the next start. Draining petrol into a can by the roadside is also genuinely risky. ## Why petrol in a diesel occurs so easily It is rarely carelessness, and no one does it on purpose. The petrol nozzle is the smaller of the two and slips into a diesel filler with almost no resistance; a diesel nozzle mostly will not go into a petrol car at all. The forecourt makes it easy, and the error runs one way. It happens when routine and the vehicle stop matching. Courtesy car, hire car, or a motor that is brand new. One petrol and one diesel on the driveway of the same household. The pumps in a different order on a well-known forecourt. A hurried fill en route to Salisbury with a train to catch. The first fill-up in a diesel Volkswagen Golf after years of driving petrol is precisely the moment it takes place. Your hand does what it has always done when you add rain, a phone call or a back seat full of children. ## Lower Burgate motorists: how to prevent petrol in a diesel next time - Green for unleaded and black for diesel is usual in the UK — but not on each forecourt. Trust the label on the pump, not the colour. - In a motor you do not know, look inside the flap over the filler or at the cap before your first fill: plenty of vehicles state the fuel type there. - One of each in the house? Label your key to your diesel — a coloured fob, a sticker — since meaning to remember isn't enough. - Before the nozzle comes off the pump the first time you fuel a hired or new car, say "diesel" out loud. Daft, yes, but it works. - Tuck the phone away. This is an easy mistake to make whilst you're thinking about something else. - Some diesels have a filler built to reject a petrol nozzle, and devices you can add exist for cars without one. Such an inhibitor helps up to a point — as a backstop, not a reason to stop checking the pump. - Noticing it mid-fill? Stop there and then. A thinner blend results from less petrol in the tank, but your next step remains the same: don't crank it. ## Lower Burgate: already put petrol in a diesel? Short and simple, then, is the order of things. Leave it unstarted, with your ignition switched off too. Ask the attendants to help you push it clear of the pump if you're still on the forecourt, whether that's Harvest Energy or anywhere else. What went in, about how much, and if it has run: tell us that when you ring 0333 366 0103. If it was AdBlue instead of petrol, say so. That is a different fault — corrosion and deposits instead of lost protection — and it has its own page for Lower Burgate. ## Lower Burgate petrol in a diesel jobs: why one costs more than another There is no fair single quote for this, because the four situations above are four separate tasks. What moves the cost is mostly which of them you're in. Where the car is counts too, and whether our van can safely get to it, after the proportion of petrol to what your tank holds. What got in, how much, and if it's run — three questions our engineers ask before costing, not after, for precisely that reason. A range turns into a straight figure once the answers are in. ## About Lower Burgate Lower Burgate is a small hamlet situated on the riverside in Hampshire, with a low elevation of around 31 metres.
