Likely less than you already are — as long as nobody has started it. "Have I wrecked it?" is the first question everyone around Bicker asks, and the truthful answer is normally no, because petrol resting in a diesel tank harms nothing till it is drawn through the fuel system — by ignition priming, by the starter, or by driving. To keep the car that way, call Petrol in Diesel and leave the engine switched off. 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 engine: what petrol in a diesel does Diesel does two jobs on its way through an engine. It burns, and before it ignites it protects. Very fine clearances go into your injectors and the high-pressure fuel pump, and just the diesel running through stops those surfaces grinding together. The second job petrol doesn't do at all, and the first it does poorly. Being less viscous than diesel, petrol strips away the lubrication a fuel system needs, so a pump on that mixture wearing itself. It is also made to resist igniting under compression — the reverse of what a diesel needs — which is where you hear the knocking. Together, those make the shape of the problem clear. Contact doesn't do the damage — movement does. All a tank with petrol in it amounts to is a fuel fault. After your pump has been working on that petrol, a mechanical fault has started: anything shed by a pump that is wearing down travels onward to your injectors with the fuel. ## Petrol in a diesel around Bicker: how serious is it? Four situations Fuelled up, never started. The best case there is. On a forecourt, and really only there, that petrol is still confined to your tank — because everywhere else the vehicle was driven to reach it. The task is emptying and flushing on the spot. Your ignition switched on, or a short start. With the system primed, the fuel lines and filter now contain petrol that came from that tank. That is generally still a straightforward task — a drain, a flush, and your filter dealt with. Those few miles driven meant the pump working on fuel diluted by petrol throughout. Distance is only half of that; how hard it was driven matters equally. Either way this work includes your tank, your lines, the filter and clean fuel through the whole system. Driving the children to The Donington Cowley Endowed Primary School is one sort of trip. Driving as far as Peterborough, under 25 miles away, makes a very different job — as does any miles on the A1(M), under 50 miles from Bicker, with your engine labouring hard all the way. Driven until it complained. Rattling, an uneven idle, smoke, a throttle that has gone soft. That's the motor telling you its fuel no longer is acting like diesel. Pull up on the spot — on the verge on School Lane, at the kerb, down a side road — and do not move it. Lasting damage is very uncommon if a car is pulled over soon, and the fuel drain and flush-through that still go first deal with it. ## Bicker drivers and that petrol in a diesel myths they hear "Top it up the rest of the way with diesel and it will be fine" — a myth. It will not. Topping up takes out nothing; it gives you a fuller tank of the same mix. Percentage isn't how a diesel fuel system copes with petrol, whatever that advice supposes. "Current diesels can handle a little petrol" — a myth, and nearer the reverse. A newer diesel runs its fuel through finer parts at higher pressure, which makes the protection matter more, not less. Myth: "If it starts and drives, there is no harm done." This is the one that catches drivers. Any petrol motor fed diesel normally won't run, so the motorist stops and the damage stops with them. While the pump grinds, a diesel fed petrol normally starts, idles and drives away as though nothing has happened. Fine and running are not the same at all. "A drop of two-stroke oil and drive it home" — a myth, borrowed from a fix from years ago, for a different fault. What petrol has thinned remains thinned, and that petrol stays in that tank regardless. The next start draws petrol back round the pump out of the fuel lines and the filter, where some of that sits after the engine has run. That's why draining your tank yourself doesn't sort it — a myth. Besides, petrol drained into a can by the road is genuinely dangerous. ## How does petrol in a diesel take place? It's rarely carelessness, and nobody does it on purpose. The forecourt makes it simple: the petrol nozzle is the narrower of the two, and it slips into a diesel filler with almost no resistance, while a diesel nozzle mostly won't go into a petrol vehicle at all. So the error runs one way. The moment routine stops matching the vehicle is the moment it happens. A new vehicle, a hire car or a courtesy car. Households running one of each, petrol and diesel. The pumps in a different order on a familiar forecourt. A train to catch, and a rushed fill on the way to Swineshead. A new-to-you diesel Renault Megane, its first fuelling, and a motorist accustomed to petrol: exactly when it happens. With rain, a call coming in, or children to deal with, the hand just does what it has always done. ## Bicker drivers: how to prevent petrol in a diesel next time - The label is what matters, so check the pump rather than the colour: in the UK unleaded handles are usually green and diesel black, but not on every forecourt. - The first fill in a new car is the time to check the filler flap — on it, or on the cap, plenty of cars state the fuel they take. - One of each in the home? Label the key to the diesel — a coloured fob, a sticker — since intending to remember is not enough. - "Diesel", out loud, before you pick up the nozzle — every time a new or hired car needs its first tank. It sounds daft. It works. - Thinking about something else is when this becomes an easy mistake to make, so tuck your phone away and keep your mind on the pump. - Up to a point, a misfuel inhibitor helps: some diesels come with a filler built to refuse a petrol nozzle, and add-on devices are available for the rest. Count it as a safety net, then keep checking the pump. - Stop as soon as you notice. Less petrol in that tank means a thinner mix. It does not change what to do next, which is still not to crank it. ## Put petrol in a diesel in Bicker already? Then the order of things is brief. Don't turn your ignition on, and don't crank it. Ask the staff to help you push it away from the petrol pump if you're still at the forecourt, whether that is Esso or anywhere else. What got in, about how much, and if it has run: tell us those when you ring 0333 366 0103. Say so if it was AdBlue instead of petrol: it's a different fault, with its own page for Bicker, since AdBlue brings corrosion and deposits rather than lost protection. ## Bicker petrol in a diesel jobs: why one costs more than another There's no fair single price for this, because the four situations above are four different tasks. The scenario itself does most of the work of moving your cost. Where the vehicle is matters too, and whether a van can safely reach it, after the share of petrol to what the tank holds. Ahead of any quote, not after, come three queries: the fuel that was put in, its quantity, and if it's run. That's why. The replies turn a range into a straight figure. ## About Bicker and its setting Bicker is a small village in southern Lincolnshire, situated near the fenland edge and close to the River Witham.
