How Worried to Be Likely less than you are now — provided no one has started the vehicle. Until the ignition primes your pump, the starter turns, or the vehicle is driven, petrol in a diesel tank simply sits there and does no harm. Which means the honest reply to the first Stretton question — "have I wrecked it?" — normally no. To keep the car like that, call Petrol in Diesel then leave the engine alone. Further down, this page sets out what petrol actually does inside a diesel, how far it might have gone, and how to stop it happening to you again. ## Inside your engine: what petrol in a diesel does Diesel does two tasks on its way through an engine. Before it burns, it protects — and then it burns. Made to very fine gaps, the injectors and the pump depend on your diesel flowing through them to keep their surfaces from wearing against one another. The second job petrol does not do at all, and the first it does badly. It is runnier than diesel and removes the lubrication the system hinges on, so a pump running on a petrol mix is a pump wearing itself. And petrol is designed to resist igniting under compression, which is the opposite of what a diesel needs from its fuel. That's where the clattering comes from. Seen together, they show the shape the problem has. It is circulation that causes the damage, not contact. Any tank with petrol in it is a fuel issue. Whatever a worn pump sheds travels on, borne by your fuel, into the injectors downstream, which is why a pump that has been working on the petrol is where a mechanical issue starts. ## Four scenarios we see in Stretton: how bad is petrol in a diesel? Filled but never started — as good as it gets. At a forecourt, and truly only there, that petrol is still confined to your tank — because anywhere else the vehicle was driven to get to it. The job is emptying and cleaning on the spot. Your ignition switched on, or a short start. Once primed, the fuel system has drawn petrol out of that tank up to your filter and the fuel lines. Still generally easy: drain, flush, and your filter dealt with. Your pump now worked a couple of miles on diluted fuel — that is what driving the car does. Distance is only half of it; how hard it was driven matters just as much. Either way this work runs to that tank, the lines, your filter and fresh fuel through the entire circuit. Driving the children to Stretton St Matthew's CofE Primary School is one sort of trip. Very different once more: a run to Salford, under 25 miles away, or some distance on the M56, under a mile from Stretton, where the engine kept working hard. Clattering, a ragged idle, smoke, a throttle gone soft: driven until it complained. The fuel isn't behaving like diesel any more, and the motor is telling you. Pull up wherever you are — the verge on Bower Crescent, a lay-by, a side street — then leave the car there. The drain and flush-through still come first, and they take care of it: when a vehicle is stopped early, lasting damage is very uncommon. ## Stretton drivers and that petrol in a diesel myths they hear It will not be fine. The myth: "Fill it the rest of the way with diesel and it will be." Nothing is removed by topping up — you are left with a bigger tank, still the same mixture. The assumption behind the guidance — that diesel fuel systems tolerate petrol by percentage — is wrong. If anything, the opposite holds. Myth: "A modern diesel can cope with a bit of petrol." Lubrication counts more on current diesels, not less, because their fuel passes through smaller parts at higher pressure. Myth: "If it starts and drives, there's no damage done." This is the one that catches motorists. A petrol engine fed diesel usually will not run, so the motorist stops and the harm stops with them. Nothing seems to have happened when a diesel fed petrol fires up, ticks over and drives away, which it usually does; meanwhile the pump grinds. Being able to run isn't the same as being fine. Myth: a two-stroke additive makes it safe to drive home. It is an old fix, supposed for another problem. That petrol is still in that tank afterwards, and whatever it has diluted is not put back. The next start draws petrol back round the pump out of your lines and the filter, where some of that ends up after the motor has run. That is why a DIY tank drain does not sort it — a myth. Besides, petrol drained into a can by the road is genuinely dangerous. ## Petrol in a diesel: how does it happen? A careless moment is seldom the cause, and nobody means to do it. The forecourt makes it simple: the petrol nozzle is the slimmer of the two, and it slips into a diesel filler with almost no resistance, while a diesel nozzle mostly will not go into a petrol motor at all. So the slip runs one way. It happens when routine and the vehicle stop matching. Hire cars, courtesy cars, and cars that are new to you. A household with one petrol and one diesel on the driveway. Your usual forecourt, its pumps now in a different order. Fuelling up in a hurry on the way to Warrington Bank Quay, with a train to catch. A new-to-you diesel Volkswagen Golf, its first fuelling, and a motorist accustomed to petrol: exactly when it takes place. With rain, a call coming in, or a car full of children to deal with, the hand simply does what it always has. ## How to prevent petrol in a diesel on your next fill-up around Stretton - Not every forecourt in the UK follows green for unleaded and black for diesel, though most usually do. Check the petrol pump's label; the colour is only a clue. - Inspect the filler flap. Many motors state the fuel type inside the flap or on the cap. Look at it on your first fill in a vehicle you do not know. - A coloured fob or a sticker on the diesel's key does more than any amount of intending to remember, for a home with one of each. - Before the nozzle leaves the petrol pump the first time you fuel a hired or new vehicle, say "diesel" aloud. Daft, yes, yet it works. - Thinking about something else is when this becomes an easy mistake to make, so tuck the phone away then keep your mind on the pump. - Up to a point, a misfuel inhibitor helps: some diesels have a filler designed to block a petrol nozzle, and add-on devices exist for the remainder. Count it as a safety net, then keep reading the pump. - As soon as you notice, stop: less petrol inside your tank makes a weaker mixture. What to do next doesn't change, though — still don't fire it up. ## Already put petrol in a diesel in Stretton? Then, there is just a short order of things. Leave it unstarted, with your ignition switched off as well. If you're still on the forecourt — Morrisons or anywhere else — ask the staff to help you push the vehicle away from the pump. What was put in, about how much, and whether it has run: tell us those when you call 0333 366 0103. If it was AdBlue instead of petrol, say so. That is a separate problem — corrosion and deposits and not lost protection — and it has its own page for Stretton. ## Why one petrol in a diesel task in Stretton costs more than another The four situations above are four different tasks, so no single quote for this would be fair. Which of them you're in is chiefly what moves the cost. After that it's the share — how much petrol went in against how much the tank holds — and then where the car is and whether our van can get to it safely. Before any quote, not after, we ask three queries: your fuel that got in, its amount, and whether it has run. That is why. The answers change a range into a straight figure. ## About Stretton itself Stretton is a small village in Cheshire, situated inland at an elevation of around 85 metres.
