Not started? Then less anxious than you probably feel. Everyone around Hall Green starts with "have I ruined it?", and the fair answer is usually no: petrol left in that tank of a diesel stays harmless till priming, cranking or driving pulls it into the fuel system. To keep the car that way, call Petrol in Diesel then leave your engine switched off. Below, you will find what petrol really does inside a diesel, how far it might have got, and how to stop it happening to you a second time. ## What petrol in a diesel does to the engine Two tasks fall to diesel on its journey round a motor. It protects to begin with, and after that does it burn. Very fine clearances are built into the fuel injectors and the high-pressure fuel pump, and only the diesel flowing through keeps their surfaces from grinding together. Of those two tasks, petrol handles the first badly and the second not at all. The knocking comes from petrol being designed not to ignite when compressed, which is precisely the opposite of what a diesel needs. On top of that it is runnier than diesel, it strips away the protection the fuel system rests on, and any pump working on that mixture is wearing itself. Seen together, they show what shape the trouble has. Contact doesn't do the damage — circulation does. Where that petrol is only inside that tank, it is a problem of fuel, nothing more. After your pump has been labouring on that petrol, a mechanical issue has started: anything shed by a pump that's wearing down travels onward to the injectors with the fuel. ## Hall Green, petrol in a diesel: four cases, from mild to serious The best case there can be: filled up, never started. On a forecourt, and really only there, that petrol is still confined to that tank — since anywhere else the vehicle was driven to reach it. The job is draining and cleaning on the spot. Your ignition turned on, or a short start. Once primed, the fuel system has pulled petrol from that tank up to your filter and the lines. Still generally straightforward: drain, flush, and the fuel filter sorted. Your pump has spent a couple of miles on thinned fuel — that's what driving the vehicle meant. The work is your tank, the fuel lines, your filter and fresh fuel through the entire system, and how hard the vehicle was driven counts as much as how far. A school run to St Thomas the Martyr Voluntary Aided Church of England Primary School is one matter. Very different once more: a trip to Liverpool, under 15 miles away, or any distance on the M58, under a mile from Hall Green, where the motor never stopped labouring hard. Driven on till it protested — rattling, smoke, a ragged idle, a dead throttle. The fuel is not acting like diesel any more, and your motor is telling you. Leave it wherever it stops: a lay-by, a side street, the verge on Dearden Way. What goes first is still the fuel drain and flush-through, and that sorts it out, with permanent damage very unusual if a vehicle is pulled over quickly. ## What Hall Green motorists get told about petrol in a diesel — and the myths in it "Top it up the rest of the way with diesel and it will be fine" — a myth. It will not. Nothing is removed when you top up — your tank simply holds more of the same mixture. That guidance assumes a diesel fuel system handles petrol by percentage. It doesn't. If anything, the reverse holds. Myth: "A newer diesel can cope with a bit of petrol." At higher pressure, through finer parts: that is how a current diesel handles its fuel, so the protection matters for more, not less. Myth: "If it starts and drives, there's no harm done." This is the one that fools people. The motorist of a petrol motor fed diesel normally stops, because it will not run, and the damage stops there. A diesel fed petrol usually starts, idles and drives away as if nothing has happened, whilst the pump grinds. Fine and running are not the same at all. Myth: "Add some two-stroke oil and drive it home." It's an old workaround for a distinct issue. None of what petrol weakened is put back by it — and later, the tank still holds the petrol. The next start draws petrol back round your pump from the lines and the fuel filter, where some of it ends up once the engine has run. That is why a DIY tank drain doesn't sort it — a myth. Besides, petrol drained into a can by the road is genuinely dangerous. ## Petrol in a diesel: how does it take place? On purpose? Never. Through carelessness? Rarely, if ever. One way only, since of the nozzles: the slimmer petrol one slips inside a diesel filler with almost no resistance, while the diesel one generally will not fit a petrol motor. That's how the forecourt makes it easy. When habit and your car stop matching, it takes place. Courtesy car, hire car, or a car that's brand new. One petrol and one diesel on the driveway of the same household. Your usual forecourt, its pumps now in a different order. Fuelling up in a hurry on the way to Upholland, with a train to catch. A new-to-you diesel Renault Megane, its first fuelling, and a motorist used to petrol: exactly when it happens. Throw in a back seat full of children, a phone call or rain, and the hand takes over. ## Avoiding petrol in a diesel next time you fill up around Hall Green - Green for unleaded and black for diesel is normal in the UK — but not on every forecourt. Trust the label on the pump, not the colour. - Many cars state the fuel type inside the filler flap or on the cap, and so check it on the first fill in any motor you do not know. - Mark your key. In a household with one of each, a coloured fob or a sticker on your diesel's key does more than any amount of meaning to remember. - "Diesel", aloud, 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, 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 reject a petrol nozzle, and add-on devices are available for the rest. Count it as a backstop, then keep checking the petrol pump. - Noticing it mid-fill? Stop there and then. A thinner mixture results from less petrol inside the tank, but the next stage remains the same: don't crank it. ## Already put petrol in a diesel in Hall Green? Then the order of things is brief. Never crank it, and don't turn the ignition on. If you are still at the forecourt — Texaco or anywhere else — ask the staff to help you push the car clear of the petrol pump. Next, 0333 366 0103. We'll ask what went in, roughly how much, and if it's been run. Corrosion and deposits are the trouble with AdBlue, whereas petrol means lost lubrication. So if it was AdBlue, say so — and see its own Hall Green page. ## What makes one Hall Green petrol in a diesel task cost more than the next The four situations above are four separate tasks, so no single quote for this would be honest. Mostly, your cost shifts with which situation you are in. Where the vehicle is matters too, and whether our van can safely get to it, after the proportion of petrol to what the tank takes. Ahead of any quote, not after, come three questions: the fuel that got in, its quantity, and if it's run. That is why. Their answers are what change a range into one firm number. ## About Hall Green and its setting Hall Green is a suburban area in Lancashire, situated inland at an elevation of 127 metres, approximately 13.6 miles from Liverpool.
