How Worried to Be Unstarted? Then less anxious than you likely are. "Have I ruined it?" is the first thing everyone around Chilton Leys asks, and the truthful answer is usually no, because petrol resting in a diesel tank harms nothing until it's drawn through the system — by ignition priming, by the starter, or by driving. Petrol in Diesel is who to call, with your motor kept off, so it remains that way. Keep reading for three things: the effect petrol has inside a diesel motor, the clues of how far it has spread, and ways to make sure you never repeat it. ## Inside your engine: what petrol in a diesel does Diesel does two tasks on its way through an engine. It protects first, and after that does it burn. Very fine tolerances go into the fuel injectors and the high-pressure fuel pump, and just the diesel flowing through keeps their surfaces from grinding together. Poorly at the first, not at all at the second: that's petrol. The rattling 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 thinner than diesel, it strips away the protection the fuel system rests on, and any pump running on such a mix is wearing itself. The shape of the trouble is clear once you put those together. Contact does not do the harm — movement does. A tank with petrol in it is a fuel issue. A pump that has been working on that petrol is the beginning of a mechanical one, and whatever a worn pump sheds travels on with your fuel to the fuel injectors downstream. ## Chilton Leys, petrol in a diesel: four situations, from mild to significant Filled up, and not started: nothing beats it. Being on a forecourt is what makes this possible: elsewhere, your car has been driven there to begin with. With that petrol kept inside the tank alone, it's drained and rinsed right where it stands, and nothing more is needed. A moment's running, or merely the ignition on. Once primed, the fuel system has drawn petrol from the tank up to the filter and your lines. Drain, flush, see to the filter: still usually simple. Some miles driven, and the pump has spent every one of them working on diluted fuel. Distance is only half of it; how hard it was driven matters just as much. Either way the work includes your tank, your lines, the filter and fresh fuel through the whole system. On the school run to Grace Cook Primary School, the distance is small. Very different once more: a trip to Colchester, under 25 miles away, or any miles on the M11, under 50 miles from Chilton Leys, where your engine never stopped labouring hard. Driven on till it complained — rattling, smoke, an uneven idle, a soft throttle. The engine is telling you the fuel is no longer acting like diesel. Stop where you are — on the verge on Northfield Road, at the kerb, down a side road — and don't move it again. The drain and flush still come first, and they take care of it: if a car is stopped early, lasting damage is very uncommon. ## Chilton Leys people and the petrol in a diesel stories they hear Myth: "Fill it the rest of the way with diesel and it'll be fine." It will not. Topping up takes out nothing; it gives you a bigger tank of the same mix. A diesel fuel system doesn't tolerate petrol by percentage in the way that advice supposes. Myth: "A newer diesel can cope with a bit of petrol." If anything, the reverse. More precise parts and higher pressure are the way a newer diesel runs its fuel, and that makes the lubrication count more, not less. "It starts, it drives, and so no harm done" — the myth that catches most drivers than any other. A petrol motor fed diesel usually will not run, so the driver stops and the damage stops with them. Feed petrol to a diesel and it generally starts, ticks over and pulls away like nothing happened — all the while its pump is wearing. Being able to run isn't the same as being fine. Not so: a two-stroke additive makes it safe to drive home. It is an old workaround, supposed for another issue. It does not put back what petrol has thinned, and the petrol is still in your tank later. If the motor has been run, part of that petrol sits in your filter and the fuel lines, not the 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 hold. It is also truly hazardous to drain petrol into a can by the kerbside. ## How does petrol in a diesel take place? On purpose? Never. Through carelessness? Rarely, if ever. The forecourt makes it easy: the petrol nozzle is the slimmer of the two, and it slips into a diesel filler with almost no resistance, while a diesel nozzle generally will not go into a petrol vehicle at all. So the mistake runs one way. When habit and the car stop matching, it occurs. A car that's new to you — a hire car, on loan as a courtesy car, or brand new. Two cars on one drive, one petrol, one diesel. A well-known forecourt with the pumps in a different order. A hurried fill en route to Stowmarket with a train to catch. A new-to-you diesel Volkswagen Golf, its first fuelling, and a driver used to petrol: exactly when it occurs. The hand repeats what it has always done when you add rain, a phone call or a back seat full of kids. ## Preventing petrol in a diesel next time you fill up around Chilton Leys - The label is what counts, so check the petrol pump instead of the colour: in the UK unleaded handles are normally green and diesel black, but not on every forecourt. - Inspect your filler flap. Plenty of motors state the fuel inside the flap or on the cap. Look at it on the first fill in any car 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 intending to remember. - "Diesel", out loud, before you pick up the nozzle — each time a new or hired car needs its first tank. It seems daft. It works. - Thinking about something else is when this becomes an easy mistake to make, 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 block a petrol nozzle, and add-on devices are available for the remainder. Treat it as a safety net, and keep reading the petrol pump. - Stop the moment you realise. Less petrol inside your tank means a thinner mix. It does not change what to do next, which is still not to start the car. ## Already put petrol in a diesel in Chilton Leys? In that case, there's just a short order of things. Don't fire it up, and do not switch the ignition on. The staff at the forecourt — whether at BP itself or wherever you filled up — will usually help roll it clear of the pump if you ask. Then call 0333 366 0103 and tell us what was put in, about how much, and whether it's run. Corrosion and deposits are the trouble with AdBlue, whereas petrol brings lost lubrication. So if it was AdBlue, say so — and read its own Chilton Leys page. ## What makes one Chilton Leys petrol in a diesel job cost more than the next Four separate tasks sit behind the four scenarios above — which is why there is no fair single price. The situation itself does most of the work of moving the cost. After that it is the share — how much petrol went in against how much that tank holds — and then where your car is and whether a van can get to it safely. That is why our technicians ask three queries before costing instead of after: what got in, how much, and if it's run. The replies turn a range into a straight figure. ## About Chilton Leys and its setting Chilton Leys is a locality in Suffolk, situated inland at an elevation of 57 metres, and is located approximately 66.5 miles from London.
