If it has not been started, you can worry far less than you likely are. Everyone around Goostrey begins with "have I ruined it?", and the fair answer is normally no: petrol left inside that tank of a diesel remains harmless till priming, cranking or driving draws it into the system. Petrol in Diesel is who to phone, with the engine kept off, and so it remains that way. 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 repeat it. ## Your engine and petrol in a diesel: what happens On its way through an engine, diesel has two tasks. It combusts, and before it ignites it protects. Very fine clearances go into the fuel injectors and the high-pressure pump, and just the diesel flowing through keeps those surfaces from grinding together. Petrol does the first task poorly and the second not at all. It's runnier than diesel and takes away the protection your fuel system depends on, so a pump running on a petrol mix is a pump wearing itself. And petrol is made to resist igniting under compression, which is the reverse of what a diesel needs from its fuel. That's where the clattering comes from. Seen together, they make clear what shape the issue has. Contact does not do the harm — circulation does. Petrol in a tank is a fuel problem. Whatever a worn pump sheds travels on, borne by your fuel, into the injectors further along, which is why a pump that has worked on that petrol is where a mechanical fault begins. ## How serious is petrol in a diesel? Four scenarios our technicians see around Goostrey Filled but never started — as good as it gets. That petrol is in the tank and just the tank, and the task is a drain and a flush where the vehicle stands. This is the one scenario that can only really take place on a forecourt, as anywhere else the car has been driven to get there. A brief spell of running, or merely your ignition on. The system has been primed, and so petrol has left your tank and got to the filter and your lines. Drain, flush, deal with the fuel filter: still usually straightforward. The pump has spent a few miles on weakened fuel — that's what driving it does. How hard the vehicle was driven counts as much as how far, and the work takes in that tank, the lines, the filter and clean fuel through the whole system. The school run to Goostrey Community Primary School is one thing. Getting as far as Stoke-on-Trent, under 25 miles away, makes a very different job — as does any miles on the M6, under 3 miles from Goostrey, with the motor labouring hard all the way. Driven on until it protested — knocking, smoke, a lumpy idle, a dead throttle. That is your engine telling you its fuel has stopped behaving like diesel. Leave it wherever it stops: a lay-by, a side street, the verge on Main Road. A vehicle stopped soon very rarely has permanent damage, as the fuel drain and the flush-through, which still go first, sort it out. ## Petrol in a diesel stories Goostrey motorists hear Myth: topping up to full with diesel makes it fine. It does not. Topping up takes out nothing; it gives you a bigger tank of the same mix. The idea behind that advice — that diesel fuel systems tolerate petrol by percentage — is wrong. Myth: "A modern diesel can cope with a bit of petrol." If anything, the opposite. At higher pressure, through more precise parts: that is how a newer diesel moves its fuel, so the protection counts for more, not less. "It starts, it drives, so there is no harm" — the myth that catches more people than any other. Feed diesel to a petrol engine and it normally won't run, and so the driver stops — and the damage stops with them. Nothing looks to have happened when a diesel fed petrol fires up, ticks over and drives away, which it usually does; meanwhile the pump wears. Being able to run is not the same as being fine. Not so: a two-stroke additive lets you to drive home. It is an old workaround, meant for another problem. The petrol is still in your tank after that, and what it has thinned isn't put back. The next start sends petrol back round your pump from your lines and the filter, where some of that ends up after the motor has been run. That's why draining the tank yourself does not leave you sorted — a myth. Emptying petrol into a can at the roadside is also genuinely hazardous. ## How does petrol in a diesel take place? Carelessness is rarely the cause, and no one means to do it. The forecourt makes it simple: the petrol nozzle is the smaller of the two, and it slips into a diesel filler with almost no resistance, whilst a diesel nozzle mostly won't go into a petrol car at all. So the error runs one way. It takes place when routine and your car stop matching. A new motor, a hire car or a courtesy car. A household with one petrol and one diesel on the driveway. The pumps in a different order on a well-known forecourt. A hurried fill on the way to the nearest station with a train to catch. A new-to-you diesel Volkswagen Passat, its first fuelling, and a driver accustomed to petrol: exactly when it occurs. With rain, a call coming in, or a car full of children to deal with, the hand just does what it has always done. ## How to avoid petrol in a diesel at your next fill-up around Goostrey - Not every forecourt in the UK keeps to green for unleaded and black for diesel, though most generally do. Read the petrol pump's label; the colour is just a hint. - Check the filler flap. Plenty of vehicles state the fuel type inside the flap or on the cap. Look at it on the first fill in a vehicle you do not know. - Label 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. - Before the nozzle leaves the petrol pump the first time you fill a hired or new vehicle, say "diesel" aloud. Silly, yes, but it works. - Thinking about something else is when this becomes an easy mistake to make, and so put the phone away then keep your mind on the petrol pump. - Some diesels have a filler designed to block a petrol nozzle, and devices you can add exist for cars without one. Such an inhibitor helps up to a point — as a safety net, not a reason to stop checking the petrol pump. - As soon as you notice, stop: less petrol in the tank makes a thinner mixture. What to do next does not change, though — still do not fire it up. ## Goostrey: already put petrol in a diesel? Then, there's only a short order of things. Don't crank it, and don't turn your ignition on. Ask the staff to help you push it away from the petrol pump if you are still at the forecourt, whether that is Texaco or somewhere else. Then ring 0333 366 0103 and tell us what was put in, about how much, and whether it has run. Corrosion and deposits form the problem with AdBlue, where petrol brings lost protection. So if it was AdBlue, say so — and read its own Goostrey page. ## Goostrey petrol in a diesel jobs: why one costs more than another An honest single price does not exist here: four situations, four separate jobs. Which of them you are in is chiefly what moves your cost. Where the car is counts too, and whether a technician can safely reach it, after the ratio of petrol to what your tank takes. Before any quote, not after, we ask three questions: the fuel that was put in, the volume, and whether it has run. That's why. The answers turn a range into a straight figure. ## About Goostrey itself Goostrey is a small village in Cheshire, situated on the banks of the River Dane at an elevation of around 71 metres.
