How Worried to Be Likely less than you already are — as long as no one has started it. "Have I wrecked it?" is the first thing anyone in Pittulie asks, and the truthful answer is usually no, because petrol left in a diesel tank hurts nothing till it is dragged through the system — by ignition priming, by your starter, or by driving. To keep the car like that, call Petrol in Diesel and leave your engine switched off. Further down, you will find what petrol actually does inside a diesel, how far it may have gone, and how to stop it happening to you a second time. ## What petrol in a diesel does to the motor Passing through a motor, diesel does two jobs at the same time. Before it combusts, it lubricates — and then it ignites. Very fine gaps are built into the fuel injectors and your high-pressure pump, and only your diesel running through keeps those surfaces from grinding together. Badly at the first, not at all at the second: that's petrol. A pump working on a petrol mixture is wearing itself out, since petrol is thinner than diesel and takes away the lubrication the fuel system relies on. Petrol is also designed to resist igniting under compression — the opposite of what a diesel wants from its fuel — and that is where any rattling starts. Put these together and the shape of the trouble is plain. Contact doesn't do the damage — circulation does. Where that petrol is only in your tank, it's a fault of fuel, nothing more. Whatever a worn pump sheds goes on, borne by your fuel, into your injectors further along, which is why a pump that has worked on the petrol is where a mechanical problem begins. ## Pittulie, petrol in a diesel: four situations, from mild to significant The best case there is: filled up, not once started. That petrol is in that tank and only that tank, and the job is a drain and a flush where the vehicle stands. This is the one scenario that can only really take place on a forecourt, since anywhere else the vehicle has been driven to get there. Started for a second, or only your ignition on. Once primed, the system has pulled petrol from the tank up to your filter and your lines. Usually nothing more than clearing, cleaning and sorting your filter, and so still simple. Your pump now worked a few miles on weakened fuel — that's what driving the vehicle does. The work is the tank, your lines, the filter and fresh fuel through the whole circuit, and how hard the car was driven matters as much as how far. On the school run to the local primary school, the miles is short. Very different a second time: a trip to Aberdeen, under 50 miles away, or any mileage on the M90, over 50 miles from Pittulie, where the motor never stopped labouring hard. It complained, and only then stopped: smoke, rattling, a throttle gone soft, an idle gone lumpy. What you are hearing is your engine signalling fuel that no longer acts like diesel. Pull up on the spot — on the verge on High Street, at the kerb, down a side road — and do not move it. The fuel drain and flush-through still come first, and they take care of it: if a car is stopped quickly, lasting damage is very rare. ## Petrol in a diesel myths Pittulie motorists hear It will not be fine. The myth: "Fill it the rest of the way with diesel and it will be." Topping up removes nothing; it gives you a fuller tank of the same mix. The assumption behind that advice — that diesel fuel systems accept petrol by percentage — is wrong. Myth: a current diesel copes with a bit of petrol. Rather, the reverse. At higher pressure, through more precise components: that is how a newer diesel moves its fuel, and so the protection counts for more, not less. Myth: "If it starts and drives, there is no damage done." This is the one that catches people. The driver of a petrol engine fed diesel normally stops, because it will not run, and the damage stops with them. While the pump wears, a diesel fed petrol usually starts, ticks over and drives away as though nothing has happened. Being able to run is not the same as being fine. Myth: "Add some two-stroke oil and drive it home." It's an old fix for a different issue. What petrol has thinned stays thinned, and the petrol stays inside your tank anyway. If the motor has been run, part of the petrol sits in the filter and your lines, not your tank — and the next start sends it right back through your pump. So the myth "drain your tank yourself and you are sorted" doesn't stand up. It is also truly dangerous to drain petrol into a can at the kerbside. ## Petrol in a diesel: how does it take place? A careless moment is rarely the cause, and no one means to do it. One way only, since of the nozzles: the narrower petrol one slides inside a diesel filler with almost no resistance, while the diesel one generally won't fit a petrol car. That is how the forecourt makes it easy. Routine and the vehicle falling out of step is how it takes place. Any car that's new to you — a hire car, on loan as a courtesy car, or brand new. A household with one petrol and one diesel on the driveway. Your normal forecourt, its pumps suddenly in a different order. A rushed fill en route to the nearest station with a train to catch. Years of petrol vehicles behind you, a diesel Volkswagen Passat in front of you on the forecourt for its first tank — that is when. Add a back seat full of children, a phone call or rain, and the hand takes over. ## Pittulie drivers: how to avoid petrol in a diesel next time - Green for unleaded and black for diesel is normal in the UK — yet not on each forecourt. Go by the label on the pump, not the colour. - In a car you do not know, look inside the flap over the filler or at the cap before your first fill: many vehicles state the fuel type there. - Mark the key. In a household with one of each, a coloured fob or a sticker on the diesel's key does more than any amount of meaning to remember. - Before the nozzle leaves the petrol pump the first time you fuel a hired or new vehicle, say "diesel" out loud. Daft, perhaps, but it does the trick. - Thinking about something else is when this becomes an easy mistake to make, and so put the phone away and keep your mind on the pump. - Up to a point, a misfuel inhibitor helps: some diesels come with a filler designed to block a petrol nozzle, and add-on devices are available for the remainder. Count it as a safety net, then keep checking the pump. - Spotting it halfway? Stop at once. A thinner mixture results from less petrol inside your tank, yet the next step stays the same: do not start the vehicle. ## Petrol already in a diesel around Pittulie? Start here Then the order of things is short. Do not turn your ignition on, and don't fire it up. Still on the forecourt, at Asda or anywhere else? Ask the attendants to help you push the car clear of the petrol pump. Ring 0333 366 0103 next, with three facts — your fuel, the approximate volume, and if it's run. Say so if it was AdBlue instead of petrol: it is a separate problem, with its own page for Pittulie, because AdBlue brings corrosion and deposits instead of lost lubrication. ## Why one petrol in a diesel job in Pittulie costs more than another Four separate jobs sit behind the four situations above — which is why there's no fair single price. The scenario itself does most of the work of moving the cost. After that it's the share — how much petrol was put in against how much your tank holds — and after that where your car is and whether a technician can reach it safely. What was put in, how much, and whether it has run — three questions our technicians ask before quoting, not after, for exactly that reason. The replies turn a range into a straight figure. ## About Pittulie and where it is Pittulie is a small coastal village in Aberdeenshire, situated near the towns of Sandhaven and Rosehearty.
