Far less than you likely are, provided it hasn't been started. "Have I ruined it?" is the first thing everyone around Bradford-on-Tone asks, and the truthful answer is generally no, because petrol resting in a diesel tank hurts nothing until it's dragged through the system — by ignition priming, by the starter, or by driving. Keep it that way: leave your motor off and phone Petrol in Diesel. Read on for three things: the effect petrol has inside a diesel engine, the clues of how far it has spread, and ways to make sure you don't repeat it. ## The engine and petrol in a diesel: what goes on Two tasks fall to diesel on its journey round a motor. Oiling comes before burning; it does both. Extremely fine tolerances are built into the fuel injectors and the high-pressure fuel pump, and only your diesel running through stops their surfaces grinding together. Petrol handles the first job badly and the second not at all. A pump working on a petrol mixture is wearing itself out, since petrol is runnier than diesel and strips out the protection the fuel system relies on. Petrol is also made to resist igniting under compression — the reverse of what a diesel wants from its fuel — and that's where any knocking comes. The shape of the problem is clear when you put those together. It's circulation that causes the harm, not contact. All a tank with petrol in it amounts to is a fuel issue. The start of a mechanical one is a pump that has been labouring on that petrol — and whatever a worn pump sheds moves on with the fuel to the injectors beyond it. ## Petrol in a diesel in Bradford-on-Tone: how bad is it? Four situations Filled up, and never started: no case is better. Being at a forecourt is what makes this possible: elsewhere, the car has been driven there to begin with. With the petrol held inside your tank alone, it is cleared and rinsed on the spot, and nothing more is needed. A moment's running, or merely your ignition on. Once primed, the fuel system has drawn petrol from your tank as far as your filter and the fuel lines. Drain, flush, see to your filter: still normally straightforward. The pump has spent a few miles on thinned fuel — that's what driving it does. Distance is only half of it; how hard it was driven counts equally. Either way this work runs to that tank, the fuel lines, your filter and clean fuel through the whole system. Short trips, such as the school run to West Buckland Primary School, are one thing. A run as far as Exeter, under 25 miles away, is a very different job. So is any mileage on the M5, under 3 miles from Bradford-on-Tone, where the engine has been working hard throughout. Driven on until it complained — clattering, smoke, a ragged idle, a soft throttle. That's the motor telling you its fuel has stopped behaving like diesel. Whether it is the verge on Gardners Close, a lay-by or a side road, stop where you are then leave it. Permanent damage is very rare when a car is stopped soon, and the drain and flush that still come first deal with it. ## Petrol in a diesel myths Bradford-on-Tone people hear It will not be fine. The myth: "Fill it the rest of the way with diesel and it will be." A fuller tank of the same mix is all you get, because topping up removes nothing. That guidance assumes a diesel fuel system handles petrol by percentage. It doesn't. "Current diesels can handle a little petrol" — a myth, and nearer the reverse. Lubrication matters more on current diesels, not less, since their fuel runs through finer parts at higher pressure. "It starts, it drives, and so there is no harm" — the myth that catches most drivers than any other. A petrol engine fed diesel normally won't run, so the driver stops and the harm stops with them. While the pump wears, a diesel fed petrol normally starts, idles and drives away as if nothing has happened. Running does not mean fine. An outdated fix for a different problem lies behind this one. Myth: "Add some two-stroke oil and drive the vehicle home." It doesn't put back what petrol has diluted, and the petrol is still inside the tank after that. "Drain it yourself and you're sorted" — a myth, because after it has been running some petrol sits in the filter and lines, ready to go straight back through your pump on your next start. Besides, petrol emptied into a can by the road is truly dangerous. ## How petrol ends up: petrol in a diesel On purpose? Never. Through carelessness? Seldom, if ever. The petrol nozzle is the slimmer of the two and slips into a diesel filler with almost no resistance; a diesel nozzle generally will not go into a petrol vehicle at all. The forecourt makes it simple, and the error runs one way. Routine and your car falling out of step is how it happens. A new vehicle, a hire car or a courtesy car. One petrol and one diesel on the drive of the same household. The pumps in a different order on a familiar forecourt. A rushed fill on the way to Taunton with a train to catch. The first fill-up in a diesel Volkswagen Tiguan after years of driving petrol is exactly the moment it occurs. Add a back seat full of kids, a phone call or rain, and habit takes over. ## How to avoid petrol in a diesel on your next fill-up around Bradford-on-Tone - Green for unleaded and black for diesel is usual in the UK — but not on each forecourt. Go by the label on the pump, not the colour. - The first fill in a new car is the time to check the filler flap — on it, or on the cap, plenty of vehicles state the fuel they take. - Label your key. In a home with one of each, a coloured fob or a sticker on your diesel's key does more than any amount of intending to remember. - It seems silly and it does the trick: on your first fill in a new or hired car, say "diesel" out loud before you take the nozzle off the pump. - Tuck your phone away. This is an easy mistake to make whilst you are thinking about something else. - Add-on devices exist for motors without one, and some diesels come with a filler that won't take a petrol nozzle. Useful — but a backstop at best, never a reason to stop checking the label. - Less petrol means a weaker blend, so stop the moment you realise — while remembering that your next step is unchanged. It's still not to crank it. ## Bradford-on-Tone: already put petrol in a diesel? Short and simple, then, is the order of things. Don't fire it up, and do not switch the ignition on. The staff at the forecourt — whether at Texaco itself or wherever you filled up — will normally help roll it away from the petrol pump if you ask. Then call 0333 366 0103 and tell us what went in, about how much, and if it's run. Say so if it was AdBlue instead of petrol: it is a separate problem, with its own page for Bradford-on-Tone, because AdBlue brings corrosion and deposits rather than lost lubrication. ## One petrol in a diesel task in Bradford-on-Tone costs more than another. Why? A fair single quote doesn't exist here: four scenarios, four separate tasks. What shifts your cost is chiefly which of them you're in. Two things follow that: the petrol that was put in as a proportion of what the tank takes, then the spot the car is in and whether a van can get to it safely. Before any quote, not after, we ask three queries: your fuel that was put in, the amount, and whether it's run. That's why. Their replies are what turn a range into one firm number. ## About Bradford-on-Tone and where it is Bradford-on-Tone is a village situated in the Somerset countryside, near the River Tone, at an elevation of around 43 metres.
