Petrol in a Diesel Car in Lords Wood If it hasn't been started, you can worry less than you likely are. "Have I wrecked it?" is the first thing everyone in Lords Wood asks, and the truthful answer is normally no, because petrol resting in a diesel tank hurts nothing until it is drawn through the system — by ignition priming, by the starter, or by driving. To leave it that way, phone Petrol in Diesel then leave the engine alone. Read on for three things: the effect petrol has inside a diesel motor, the signs of how far it has spread, and ways to make sure you don't do it again. ## Your engine and petrol in a diesel: what happens On its way through a motor, diesel has two jobs. It lubricates to begin with, and after that does it burn. Made to very fine gaps, your injectors and your pump depend on your diesel flowing through them to keep their surfaces from wearing against one another. Poorly at the first, not at all at the second: that's petrol. A pump working on a petrol mix is wearing itself out, since petrol is thinner than diesel and takes away the protection your fuel system relies on. Petrol is also designed to resist igniting under compression — the opposite of what a diesel needs from its fuel — and that is where the rattling comes. Put those together and the shape of the trouble is clear. The harm is done by movement, not by contact. Any tank with petrol in it is a fuel fault. Once the pump has been running on that petrol, a mechanical problem has started: anything shed by a pump that is wearing down is carried onward to the fuel injectors with the fuel. ## Petrol in a diesel in Lords Wood: how serious is it? Four situations Fuelled up, never started. The best case there is. On a forecourt, and truly only there, that petrol is still confined to your tank — since everywhere else the car was driven to get to it. The task is draining and rinsing on the spot. Your ignition turned on, or a brief start. Petrol has come out of that tank and reached the fuel filter and the fuel lines, since the system has been primed. Still normally straightforward: drain, flush, and your filter sorted. Those few miles on the road meant your pump running on fuel diluted by petrol the whole way. Tank, lines, filter, then fresh fuel put through the entire circuit: that is the work, and the way your car was driven counts as much as the distance. The school run to Lordswood School is one thing. Very different a second time: a run to Southend-on-Sea, under 25 miles away, or some miles on the M2, under a mile from Lords Wood, where your engine kept labouring hard. Driven until it protested. Clattering, a ragged idle, smoke, a throttle that has gone soft. That's your engine telling you its fuel has stopped acting like diesel. Pull up wherever you are — the verge on Swingate Close, a lay-by, a side street — and leave the car where it is. A car stopped quickly very rarely has lasting damage, because the drain and the flush-through, which still go first, take care of it. ## Lords Wood motorists and that petrol in a diesel myths they hear Myth: topping up to full with diesel makes it fine. It does not. Nothing is removed by topping up — you're left with a bigger tank, still the same mixture. A diesel fuel system does not tolerate petrol by percentage in the way that guidance supposes. "Modern diesels can handle a little petrol" — a myth, and closer to the opposite. A newer diesel runs its fuel through finer components at higher pressure, which makes the protection count more, not less. Myth: "If it starts and drives, there's no damage done." This is the one that catches drivers. Feed diesel to a petrol motor and it generally will not run, so the motorist stops — and the damage stops with them. While the pump grinds, a diesel fed petrol normally starts, ticks over and drives away as if nothing has happened. Running is not the same as fine. An old workaround for a separate problem lies behind this one. Myth: "Add some two-stroke oil and drive it home." None of what petrol thinned gets put back by it — and afterwards, the tank still contains that petrol. Once the motor has run, part of that petrol sits in the filter and your lines, not your tank — and the next start sends it right back through your pump. So the myth "drain that tank yourself and you are sorted" does not hold. Also, a can of petrol drained by the roadside is genuinely dangerous. ## How petrol ends up: petrol in a diesel Carelessness is seldom the cause, and no one means to do it. One way only, because of the nozzles: the narrower petrol one slides inside a diesel filler with almost no resistance, while the diesel one mostly will not fit a petrol motor. That's how the forecourt makes it easy. It takes place when habit and the vehicle stop matching. Courtesy car, hire car, or a car that's brand new. Two vehicles on one driveway, one petrol, one diesel. The pumps in a different order on a well-known forecourt. Fuelling up in a rush en route to Chatham, with a train to catch. A new-to-you diesel Volkswagen Golf, its first fuelling, and a driver used to petrol: precisely when it occurs. Throw in a back seat full of children, a phone call or rain, and habit takes over. ## Lords Wood motorists: how to avoid petrol in a diesel next time - Not every forecourt in the UK follows green for unleaded and black for diesel, even if most generally do. Read the pump's label; the colour is just a hint. - The first fill in an unfamiliar car is the time to check the filler flap — inside it, or on the cap, plenty of motors state which fuel they take. - 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 sounds silly and it works: on the first fill in a new or hired car, say "diesel" aloud before you lift the nozzle off the pump. - 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. - Add-on devices are available for vehicles without one, and some diesels come with a filler that will not accept a petrol nozzle. Helpful — but a backstop at best, never a reason to stop checking the label. - As soon as you notice, stop: less petrol in that tank means a weaker mix. What to do next does not change, though — still do not start it. ## Put petrol in a diesel around Lords Wood already? The order of things is short, then. Leave it unstarted, with the ignition off as well. Yet on the forecourt, at Shell or anywhere else? Ask the staff to help you push it clear of the pump. What got in, about how much, and whether it's run: tell us that when you ring 0333 366 0103. Say so if it was AdBlue rather than petrol: it is a different issue, with its own page for Lords Wood, since AdBlue brings corrosion and deposits instead of lost lubrication. ## What makes one Lords Wood petrol in a diesel job cost more than the next Four separate jobs lie behind the four situations above — which is why there is no fair single quote. Mostly, your cost moves with which one you're in. Where the car is matters too, and whether a van can safely get to it, after the ratio of petrol to what the tank holds. Ahead of any quote, not after, we ask three questions: your fuel that was put in, the volume, and whether it has run. That is why. A range turns into a straight figure once the answers are in. ## About Lords Wood Lords Wood is a suburban area in Kent, situated inland at an elevation of 132 metres, approximately 30.9 miles from London.
