Petrol in a Diesel Car in Rafborough If it has not been started, worry far less than you probably are. Everyone in Rafborough begins with "have I ruined it?", and the fair answer is generally no: petrol left in your tank of any diesel stays harmless till priming, cranking or driving draws it into the fuel system. Keep it that way: leave the engine off then call Petrol in Diesel. The remainder of this page covers what petrol actually does to a diesel, how to tell how far it has got, and how to make sure it does not happen to you a second time. ## The engine and petrol in a diesel: what happens Passing through an engine, diesel does two things at once. Before it ignites, it lubricates — and then it ignites. Designed to extremely fine tolerances, your injectors and the pump depend on your diesel flowing through them to stop their surfaces wearing against one another. The second job petrol doesn't do at all, and the first it does poorly. Being less viscous than diesel, petrol strips away the protection a fuel system needs, so a pump running on the mixture wearing itself. It's also made to resist igniting under compression — the opposite of what a diesel needs — which is why you hear the rattling. Taken together, they make clear what shape the problem has. It is circulation that causes the harm, not contact. Petrol in a tank is a fuel problem. Once the pump has been labouring on that petrol, a mechanical problem has begun: anything shed by a pump that is grinding is carried onward to the fuel injectors with your fuel. ## Petrol in a diesel in Rafborough: how serious is it? Four situations Fuelled, and never started: nothing beats it. Being at a forecourt is what makes this possible: elsewhere, your car has been driven there to begin with. With the petrol held in your tank alone, it's cleared and rinsed on the spot, and nothing more is needed. Started for a moment, or just your ignition on. Petrol has come out of your tank and got to your filter and the lines, since the fuel system has been bled. Still generally simple: drain, flush, and your filter dealt with. Some miles driven, and your pump has spent each of them labouring on diluted fuel. The work is the tank, the fuel lines, the fuel filter and clean fuel through the entire circuit, and how hard the vehicle was driven matters as much as how far. Short trips, like the school run to Tower Hill Primary School, are one matter. Getting as far as Winchester, under 50 miles away, makes a very different task — as does any distance on the M3, under 3 miles from Rafborough, with the motor running hard the whole time. It protested, and only then stopped: smoke, clattering, a throttle gone soft, an idle gone lumpy. The fuel is not behaving like diesel any more, and your engine is saying so. Stop where you are — on the verge on Vickers Close, at the kerb, down a side road — and do not move it again. The drain and flush still go first, and they sort it out: if a vehicle is stopped soon, long-term damage is very uncommon. ## Rafborough people and that petrol in a diesel stories they hear False: topping up to full with diesel makes it fine. It doesn't. Nothing comes out when you top up — that tank just holds more of the same mixture. The assumption behind that advice — that diesel fuel systems accept petrol by percentage — is wrong. "Current diesels can handle a little petrol" — a myth, and nearer the reverse. At higher pressure, through smaller parts: that is how a modern diesel moves its fuel, so the lubrication matters for more, not less. "It starts, it drives, and so there is no harm" — the myth that trips up most motorists than any other. The driver of a petrol motor fed diesel usually stops, because it will not run, and the harm stops with them. While your pump wears, a diesel fed petrol usually starts, idles and drives away as if nothing has happened. Running does not mean fine. "A drop of two-stroke oil and drive it home" — a myth, borrowed from a fix from years ago, for a different fault. The petrol is still inside that tank after that, and whatever it has thinned isn't put back. If the motor has been run, part of that petrol is in the fuel filter and the fuel lines, not that tank — and your next start pulls it right back through the pump. So the myth "drain that tank yourself and you're sorted" doesn't stand up. And, a can of petrol filled by the roadside is genuinely dangerous. ## How does petrol in a diesel take place? No one does it on purpose, and it is rarely carelessness. One way only, because of the nozzles: the narrower petrol one slips inside a diesel filler with almost no resistance, whereas the diesel one mostly will not fit a petrol car. That is how the forecourt makes it easy. Habit and the vehicle getting out of step is how it occurs. Hire cars, courtesy cars, and motors that are new to you. One petrol and one diesel on the drive of the same household. The pumps in a different order on a familiar forecourt. A hurried fill en route to Farnborough Main with a train to catch. The first fill-up in a diesel Renault Clio after years of driving petrol is precisely the moment it takes place. With rain, a call arriving, or a car full of children to deal with, the hand just does what it has always done. ## Preventing petrol in a diesel next time you fill up around Rafborough - Check the pump, not the colour. In the UK unleaded handles are usually green and diesel black, but not on each forecourt. The label is what matters. - In a motor you do not know, look inside the flap over your filler or at the cap before the first fill: many motors state the fuel type there. - A coloured fob or a sticker on the diesel's key achieves more than any amount of intending to remember, in a home with one of each. - It seems daft and it works: on the first fill in a new or hired car, say "diesel" out loud before you lift the nozzle off the pump. - Tuck your phone away. This is an easy mistake to make while you are thinking about something else. - Some diesels have a filler designed to reject a petrol nozzle, and devices you can add are available for motors without one. Such an inhibitor helps up to a point — as a safety net, not a reason to stop checking the pump. - As soon as you realise, stop: less petrol in your tank makes a weaker mix. What to do next does not change, though — still don't start the car. ## Rafborough: already put petrol in a diesel? Short and simple, then, is the order of things. Do not start the vehicle, and don't turn your ignition on. The attendants on the forecourt — whether at Esso itself or wherever you filled up — will usually help roll it clear of the pump if you ask. Next, 0333 366 0103. We will ask what was put in, about how much, and if it's been run. AdBlue, not petrol? Then say so. Corrosion and deposits, not lost protection, make it a separate problem — Rafborough has a page just for it. ## Rafborough petrol in a diesel jobs: why one costs more than another The four situations above are four different tasks, so no single price for this would be honest. Mostly, your cost moves with which one you are in. Two things come after that: the petrol that was put in as a proportion of what the tank holds, then the place the car is in and whether a technician can get to it safely. Three queries come first, before quoting, rather than after — what was put in, how much, has it run — and this is the reason. Those answers are what change a range into one firm number. ## About Rafborough Rafborough is a suburban area situated on the riverside in Hampshire, with an elevation of around 68 metres.
