How Worried to Be Not started? Then less worried than you likely are. Petrol sitting in a diesel tank does nothing to your motor until something pulls it through the fuel system — the ignition priming your pump, your starter, or the drive itself. So the honest answer to the first query anyone in Boughton asks, "have I wrecked it?", is normally no. To keep it like that, call Petrol in Diesel and leave the engine switched off. Below, you will find what petrol actually does inside a diesel, how far it might have gone, and how to stop it happening to you a second time. ## Inside the motor: what petrol in a diesel does On its way through an engine, diesel has two jobs. Oiling comes before burning; it does both. The high-pressure pump and the injectors are made to very fine tolerances, and your diesel passing through them is what stops those surfaces from grinding against each other. The second job petrol does not do at all, and the first it does badly. A pump working on a petrol mixture is wearing itself out, since petrol is thinner than diesel and strips out the protection your fuel system depends on. Petrol is also designed to resist igniting under compression — the reverse of what a diesel wants from its fuel — and that is where any knocking starts. Put these together and the shape of the issue is plain. It's movement that causes the harm, not contact. Petrol in the tank is a fuel problem. After the pump has been working on that petrol, a mechanical problem has begun: whatever is shed by a pump that is grinding travels downstream to the injectors with the fuel. ## Petrol in a diesel around Boughton: how bad is it? Four cases The best case there can be: filled up, not once started. That petrol is inside your tank and just that tank, and the task is a drain and a flush where the car stands. This is the one scenario that can only really take place on a forecourt, as anywhere else your car has been driven to get there. Started for a second, or just your ignition on. Petrol has come out of that tank and reached your filter and the fuel lines, because your system has been bled. That's usually still an easy task — a drain, a flush, and the filter seen to. The pump now spent a couple of miles on weakened fuel — that's what driving the vehicle meant. How hard the car was driven matters as much as how far, and the work takes in the tank, the fuel lines, the filter and clean fuel through the whole circuit. The school run to St Joseph's Catholic Primary and Nursery School is one matter. A run as far as Nottingham, under 25 miles away, is a very different job. So is any mileage on the Doncaster By-Pass, under 15 miles from Boughton, where your engine has been running hard the whole time. Knocking, an uneven idle, smoke, a throttle gone soft: driven till it complained. What you are hearing is the motor reporting fuel that no longer runs like diesel. Whether it is the verge on Linton Drive, a lay-by or a side road, stop where you are and leave it. The fuel drain and flush still come first, and they take care of it: if a vehicle is stopped soon, lasting damage is very unusual. ## Stories Boughton people hear about petrol in a diesel "Top it up the rest of the way with diesel and it'll be fine" — a myth. It will not. Topping up takes out nothing; it gives you a fuller tank of the same mixture. That advice presumes a diesel fuel system handles petrol by percentage. It does not. "Current diesels can handle a little petrol" — a myth, and nearer the reverse. At higher pressure, through smaller components: that's how a modern diesel moves its fuel, and so the protection matters more, not less. The myth that catches people off guard: if it starts and drives, it must be unharmed. Diesel in a petrol motor generally means a motor that won't run: the driver stops, and so does the damage. 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. Running is not the same as fine. Myth: a two-stroke additive makes it safe to drive home. It was an old workaround, supposed for another problem. What petrol has thinned stays thinned, and the petrol remains in your tank anyway. If the engine has been run, part of the petrol sits in your filter and the lines, not your tank — and the next start pulls it straight back through the pump. So the myth "drain the tank yourself and you're sorted" does not hold. It's also genuinely risky to drain petrol into a can by the roadside. ## How petrol ends up: petrol in a diesel On purpose? Never. Through carelessness? Seldom, if ever. 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, whilst a diesel nozzle mostly will not go into a petrol car at all. So the slip runs one way. When habit and the car stop matching, it occurs. Hire cars, courtesy cars, and cars that are new to you. Households running one of each, petrol and diesel. A forecourt you know, but with its pumps arranged differently. Racing for a train outside Retford and filling up en route. Years of petrol vehicles behind you, a diesel Volkswagen Golf in front of you at the forecourt for its first tank — that's when. Add a back seat full of kids, a phone call or rain, and the hand wins. ## Boughton people: how to avoid petrol in a diesel next time - The label is what counts, so read the petrol pump instead of the colour: in the UK unleaded handles are usually green and diesel black, but not on each forecourt. - In a motor you don't know, look inside the flap over your filler or at the cap before the first fill: many motors print the fuel there. - Good intentions do less than a sticker or a fob in a vivid colour on the diesel's key when a home has one of each. So mark it. - Say it before you lift it. On your first fill in a new or hired car, say "diesel" out loud before you take the nozzle off the pump. It sounds daft and it does the trick. - Whilst you're thinking about something else, this is an easy mistake to make — so tuck your phone away. - A misfuel inhibitor helps, up to a point. Some diesels have a filler designed to reject a petrol nozzle, and add-on devices are available for cars without one. They are a backstop, not a reason to stop reading the petrol pump. - As soon as you realise, stop: less petrol inside your tank means a thinner blend. What to do next doesn't change, though — still do not crank it. ## Boughton: already put petrol in a diesel? The order of things is short, then. Never crank it, and do not turn your ignition on. Ask the staff to help you roll it away from the pump if you're still on the forecourt, whether that is Tesco or somewhere else. Next, 0333 366 0103. We will ask what went in, roughly how much, and if it has been run. If it was AdBlue instead of petrol, say so. That is a different problem — corrosion and deposits and not lost lubrication — and it has its own page for Boughton. ## What makes one Boughton petrol in a diesel task cost more than the next The four situations above are four different tasks, so no single price for this would be honest. The scenario itself does most of the work of moving your cost. Two things come after that: the petrol that went in as a proportion of what that tank takes, then the place the car is in and whether our van can get to it safely. That is why we ask three queries before pricing instead of after: what went in, how much, and if it's run. A range becomes a straight figure when those replies are in. ## About Boughton and where it is Boughton is a small village in Nottinghamshire, situated in the East Midlands region of England, with a population of around 1500 people.
