Petrol in a Diesel Car in Pickles Hill Provided it hasn't been started, worry less than you probably are. Till the ignition primes the pump, your starter turns, or your vehicle is driven, petrol in a diesel tank just rests there and does no harm. Which makes the truthful reply to the first Pickles Hill query — "have I wrecked it?" — normally no. To keep the vehicle that way, ring Petrol in Diesel then leave your motor switched off. What petrol really does to a diesel, how to gauge how far it has gone, and how to stop it from happening again: that's the rest of this page. ## Your engine and petrol in a diesel: what happens On its way through an engine, diesel does two jobs. Lubricating comes before burning; it does both. Your high-pressure pump and the fuel injectors are built to very fine gaps, and your diesel passing through them is what stops those surfaces from grinding against each other. Poorly at the first, not at all at the second: that is petrol. The rattling comes from petrol being made not to ignite when compressed, which is precisely the reverse 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 such a mix is wearing itself. Together, those make the shape of the problem clear. Not contact but circulation is what does the harm. All a tank with petrol in it amounts to is a fuel problem. The beginning of a mechanical problem is a pump that has been labouring on that petrol — and whatever a worn pump sheds travels on with your fuel to the fuel injectors downstream. ## Pickles Hill, petrol in a diesel: four cases, from mild to significant Filled up, and not started: nothing beats it. Only the tank has petrol in it, and so the job is clearing that tank and purging the system where your car stands. This scenario can only really occur on a forecourt: anywhere else, the vehicle got there by being driven. Ignition on, or started for a second. With the system primed, the fuel lines and filter already contain petrol that came from that tank. Drain, flush, deal with your filter: still normally simple. Driven a few miles. Now the pump has spent those miles working on diluted fuel. How hard your car was driven counts as much as how far, and this work covers the tank, the lines, the filter and clean fuel through the whole circuit. The school run to Southmere Primary Academy is one thing. Getting as far as Bradford, under 3 miles away, makes a very different task — as does any miles on the M606, under 3 miles from Pickles Hill, with the motor running hard all the way. Driven on till it complained — rattling, smoke, an uneven idle, a dead throttle. The fuel isn't behaving like diesel any more, and the engine is telling you. Stop wherever you are — the verge on Poplar Grove, a lay-by, a side street — then leave it where it is. What goes first is still the drain and flush, and that sorts it out, with lasting damage very unusual if a vehicle is stopped soon. ## What Pickles Hill people get told about petrol in a diesel — and the stories in it 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 mixture is all you get, since topping up takes out nothing. A diesel fuel system doesn't accept petrol by percentage in the way that advice assumes. If anything, the reverse holds. Myth: "A current diesel can cope with a bit of petrol." Smaller components and higher pressure are the way a newer diesel runs its fuel, and that makes the protection count more, not less. Myth: "If it starts and drives, there is no damage done." This is the one that fools motorists. The driver of a petrol motor fed diesel usually stops, because it will not run, and the harm stops with them. Whilst the pump grinds, a diesel fed petrol usually starts, ticks over and drives away as if nothing has happened. Running isn't the same as fine. Myth: "Add some two-stroke oil and drive the car home." It is an outdated fix for a separate issue. What petrol has weakened remains weakened, and that petrol remains inside that tank regardless. "Drain it yourself and you are sorted" — a myth, since after it's been running some petrol sits in the filter and lines, waiting to go right back through the pump on the next start. It's also really risky to drain petrol into a can at the kerbside. ## Petrol in a diesel: how does it happen? On purpose? Never. Through carelessness? Rarely, if ever. The forecourt makes it easy: the petrol nozzle is the slimmer of the two, and it slides into a diesel filler with almost no resistance, while a diesel nozzle generally will not go into a petrol motor at all. So the error runs one way. It happens when habit and the car stop matching. Hire cars, courtesy cars, and vehicles that are new to you. One petrol and one diesel on the driveway of the same household. A forecourt you know, only with its pumps laid out differently. A hurried fill en route to Bradford Interchange with a train to catch. The first fill-up in a diesel Volkswagen Golf after years of driving petrol is exactly the moment it occurs. Throw in a back seat full of kids, a phone call or rain, and habit wins. ## Avoiding petrol in a diesel next time you fill up around Pickles Hill - Not every forecourt in the UK keeps to green for unleaded and black for diesel, even if most generally do. Read the pump's label; the colour is only a clue. - The first fill in a strange car is the time to check the filler flap — inside it, or on the cap, many motors state the fuel to use. - Mark your key. In a home with one of each, a coloured fob or a sticker on the diesel's key does more than any amount of meaning to remember. - 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 while your mind is on something else, and so the phone goes away. - Some diesels have a filler designed to block a petrol nozzle, and devices you can add are available for vehicles without one. Such an inhibitor helps up to a point — as a backstop, not a reason to stop checking the pump. - As soon as you realise, stop: less petrol in that tank makes a weaker mixture. What to do next doesn't change, though — still do not crank it. ## Pickles Hill: already put petrol in a diesel? Then the order of things is short. Do not turn the ignition on, and don't start it. The attendants at the forecourt — whether at the nearest petrol station itself or wherever you filled up — will usually help roll it away from the petrol pump if you ask. Phone 0333 366 0103 next, with three answers — your fuel, the rough amount, and whether it's run. AdBlue, not petrol? Then tell us. Corrosion and deposits, not lost protection, make it a different issue — Pickles Hill has a page just for it. ## Pickles Hill petrol in a diesel tasks: why one costs more than another The four scenarios above are four different jobs, so no single quote for this would be fair. Mostly, the cost shifts with which one you're in. Where the vehicle is counts too, and whether a van can safely get to it, after the share of petrol to what that tank holds. Before any quote, not after, come three questions: the fuel that got in, the quantity, and whether it's run. That is why. Those answers change a range into a straight figure. ## About Pickles Hill itself Pickles Hill is a suburban area located near Bradford in West Yorkshire, sitting at an elevation of around 250 metres.
