Petrol in a Diesel Car in Victory Probably less than you already are — provided no one has started it. Everyone around Victory starts with "have I wrecked it?", and the fair answer is normally no: petrol resting inside the tank of any diesel remains harmless till priming, cranking or driving pulls it into the fuel system. Leave your engine off then phone Petrol in Diesel — that is how you keep it like that. What petrol actually does to a diesel, how to gauge how far it has gone, and how to stop it from happening a second time: that is the remainder of this page. ## Inside your engine: what petrol in a diesel really does Passing through a motor, diesel is doing two things at the same time. Before it burns, it protects — then it combusts. Extremely fine gaps are built into the injectors and the high-pressure pump, and only your diesel running through keeps their surfaces from grinding together. Petrol handles the first task poorly and the second not at all. It's runnier than diesel and strips away the lubrication the fuel system depends on, so a pump running on a petrol mixture is a pump wearing itself. And petrol is made to resist igniting under compression, which is the reverse of what a diesel needs from its fuel. That's where the knocking comes from. The shape of the problem is plain once you put those together. It's circulation that does the harm, not contact. Petrol in the tank is a fuel problem. A pump that has been running on that petrol is the beginning of a mechanical one, and whatever a worn pump sheds travels on with your fuel to the injectors downstream. ## Petrol in a diesel in Victory: how bad is it? Four cases Filled up, and not started: nothing beats it. Just the tank has petrol in it, and so the job is clearing the tank and rinsing your system where the vehicle stands. This scenario can only really occur on a forecourt: anywhere else, the vehicle got there by being driven. A moment's running, or just your ignition on. Once primed, the fuel system has pulled petrol from the tank as far as your filter and your lines. Still usually simple: drain, flush, and the filter seen to. The pump now spent a couple of miles on diluted fuel — that's what driving it does. The work is that tank, the lines, the filter and clean fuel through the entire system, and how hard your car was driven counts as much as how far. The school run to Oxford Grove Primary School is one matter. Any mileage on the M61, under 3 miles from Victory, means your engine working hard throughout, and a run to Salford, under 10 miles away, is a very different job too. Driven until it protested. Knocking, a lumpy idle, smoke, a throttle that has gone soft. The fuel isn't acting like diesel any more, and the motor is telling you. Leave it where it has stopped: a lay-by, a quiet street, the verge on Beatrice Road. What comes first is still the drain and flush-through, and that takes care of it, with lasting damage very unusual if a car is stopped early. ## Petrol in a diesel myths Victory motorists hear "Top it up the rest of the way with diesel and it'll be fine" — a myth. It won't. Nothing comes out when you top up — your tank simply carries more of the same mixture. That guidance presumes a diesel fuel system tolerates petrol by percentage. It does not. "Current diesels can handle a little petrol" — a myth, and closer to the opposite. At higher pressure, through smaller parts: that's how a modern diesel moves its fuel, so the protection matters for more, not less. The myth that catches motorists off guard: if it starts and drives, it must be unharmed. Feed diesel to a petrol motor and it usually will not run, and so the motorist stops — and the harm stops with them. While the pump grinds, a diesel fed petrol usually starts, idles and drives away as if nothing has happened. Fine and running aren't the same thing. Myth: "Add some two-stroke oil and drive the car home." It's an old workaround for a separate issue. What petrol has weakened remains diluted, and the petrol remains in the tank regardless. Myth: "Drain your tank yourself and you are sorted." Once your engine has been run, some of that petrol is no longer inside that tank: it's in the fuel filter and your lines, and it goes right back through the pump on the next start. Emptying petrol into a can by the kerbside is also really dangerous. ## How does petrol in a diesel occur? Carelessness is rarely the cause, and nobody means to do it. The petrol nozzle is the slimmer 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 simple, and the error runs one way. The moment habit stops matching the car is the moment it happens. Hire cars, courtesy cars, and motors that are new to you. One petrol and one diesel on the driveway of the same household. The pumps in a different order on a well-known forecourt. A train to catch, and a hurried fill en route to Bolton. A new-to-you diesel Renault Megane, its first fuelling, and a driver used to petrol: exactly when it takes place. With rain, a call arriving, or children to deal with, your hand just does what it always has. ## Next time you fill up in Victory: avoiding petrol in a diesel - Not every forecourt in the UK follows green for unleaded and black for diesel, though most usually do. Read the pump's label; the colour is just a clue. - The first fill in a strange car is the time to check the filler flap — on it, or on the cap, plenty of motors state the fuel they take. - A coloured fob or a sticker on the diesel's key does more than any amount of meaning to remember, in a household with one of each. - It seems daft and it does the trick: on the first fill in a new or hired car, say "diesel" out loud before you take the nozzle off the petrol pump. - Mistakes like this are easy to make whilst your mind is on something else, and so the phone goes away. - Add-on devices are available for vehicles without one, and some diesels come with a filler that won't take a petrol nozzle. Helpful — but a backstop at best, never a reason to stop checking the label. - The moment you notice, stop: less petrol in the tank means a thinner blend. What to do next does not change, though — still don't crank it. ## Already put petrol in a diesel in Victory? Then the order of things is short. Leave it unstarted, with your ignition switched off too. Yet at the forecourt, at Shell or anywhere else? Ask the attendants to help you push it clear of the pump. Then ring 0333 366 0103 and tell us what got in, about how much, and whether it's run. Say so if it was AdBlue instead of petrol: it's a different issue, with its own page for Victory, because AdBlue brings corrosion and deposits rather than lost lubrication. ## One petrol in a diesel task around Victory costs more than another. Why? The four situations above are four separate tasks, so no single quote for this would be fair. Which of them you're in is chiefly what shifts the cost. Where the car is counts too, and whether a van can safely get to it, after the share of petrol to what your tank takes. That is why our engineers ask three queries before costing instead of after: what went in, how much, and whether it has run. Those answers change a range into a straight figure. ## About Victory and where it is Victory is a suburban area situated near several lakes in Greater Manchester, with a mix of terraced housing and local amenities.
