How Worried to Be Less than you likely are, if it has not been started. Everyone around Uttoxeter begins with "have I wrecked it?", and the honest answer is usually no: petrol resting in that tank of any diesel remains harmless till priming, cranking or driving draws it into the system. Petrol in Diesel is who to call, with your motor kept off, and so it remains that way. Keep reading for three things: the effect petrol has inside a diesel engine, the clues of how far it has got, and ways to make sure you don't do it again. ## Petrol in a diesel: what does it do to the motor? Diesel has two tasks on its way through an engine. It ignites, and before it combusts it protects. Made to extremely fine clearances, your injectors and your pump rely on the diesel flowing through them to stop their surfaces wearing against one another. Badly at the first, not at all at the second: that is petrol. A pump working on a petrol mixture is wearing itself out, because 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 opposite of what a diesel wants from its fuel — and that is where the rattling starts. The shape of the trouble is clear when you put those together. The harm is done by circulation, not by contact. All a tank with petrol in it amounts to is a fuel issue. The start of a mechanical problem is a pump that has been labouring on that petrol — and whatever a worn pump sheds moves on with your fuel to your injectors downstream. ## Uttoxeter, petrol in a diesel: four cases, from mild to significant Filled up, never started. The best case there is. Being on a forecourt is what makes this possible: elsewhere, the vehicle has been driven there to begin with. With the petrol kept in that tank alone, it is drained and purged on the spot, and nothing more is needed. Ignition on, or started for a moment. Your system has been primed, and so petrol has left your tank and got to your filter and the lines. That is usually still an easy task — a drain, a flush, and your filter dealt with. Driven a couple of miles. Now your pump has spent those miles working on diluted fuel. Distance is only half of it; how hard it was driven matters just as much. Either way this work runs to the tank, the lines, the fuel filter and clean fuel through the whole circuit. Driving the children to Picknalls First School is one sort of trip. A run as far as Lichfield, under 25 miles away, is a very different task. So is any distance on the M6, under 15 miles from Uttoxeter, where your engine has been working hard the whole time. Knocking, an uneven idle, smoke, a throttle gone soft: driven till it complained. What you are hearing is the engine signalling fuel that no longer runs like diesel. Whether it's the verge on Carter Street, a lay-by or a side street, stop where you are and leave it. What comes first is still the fuel drain and flush-through, and that deals with it, with permanent damage very uncommon when a vehicle is stopped early. ## Petrol in a diesel myths Uttoxeter people hear False: topping up to full with diesel makes it fine. It doesn't. A bigger tank of the same mixture is all it gives, because topping up takes out nothing. That advice presumes a diesel fuel system handles petrol by percentage. It doesn't. "Modern diesels can handle a little petrol" — a myth, and nearer the opposite. At higher pressure, through finer parts: that is how a modern diesel handles its fuel, and so the lubrication matters for more, not less. Myth: "If it starts and drives, there's no damage done." This is the one that fools motorists. Diesel in a petrol motor generally leaves a motor that will not run: the motorist stops, and so does the damage. Nothing looks to have happened when a diesel fed petrol fires up, ticks over and drives away, as it usually does; meanwhile the pump wears. Fine and running are not the same at all. An old workaround for a separate issue is behind this one. Myth: "Add some two-stroke oil and drive it home." That petrol is still in your tank afterwards, and what it has weakened is not put back. The next start draws petrol back round the pump out of the lines and your filter, where some of that ends up once your engine has run. That's why a DIY tank drain doesn't sort it — a myth. Also, a can of petrol drained by the roadside is genuinely dangerous. ## How does petrol in a diesel happen? On purpose? Never. Through carelessness? Seldom, if ever. A diesel nozzle mostly won't fit a petrol motor, but the narrower petrol nozzle goes into the filler of a diesel nearly without resistance — so forecourts make this one mistake simple, and just in that direction. The moment habit stops matching the car is the moment it occurs. Hire cars, courtesy cars, and vehicles that are new to you. Two vehicles on one drive, one petrol, one diesel. A forecourt you know, but with its pumps laid out differently. A rushed fill on the way to the nearest station with a train to catch. Years of petrol motors behind you, a diesel Volkswagen Golf in front of you at the forecourt for its first tank — that is when. Add a back seat full of kids, a phone call or rain, and habit takes over. ## Preventing petrol in a diesel next time you fill up around Uttoxeter - A green handle for unleaded and black for diesel is usual in the UK — but not on every forecourt. Go by the label on the petrol pump, not the colour. - Many cars state the fuel type inside the filler flap or on the cap, and so check there on your first fill in a vehicle you do not know. - A coloured fob or a sticker on your diesel's key does more than any amount of intending to remember, in a household with one of each. - Before the nozzle leaves the petrol pump the first time you fuel a hired or new motor, say "diesel" out loud. Daft, yes, yet it works. - Tuck your phone away. This is an easy mistake to make while you're thinking about something else. - A misfuel inhibitor helps, up to a point. Some diesels have a filler designed to refuse a petrol nozzle, and add-on devices are available for vehicles without one. They are a safety net, not a reason to stop checking the petrol pump. - Stop as soon as you realise. Less petrol inside that tank makes a thinner mix. It doesn't change what to do next, which is still not to fire it up. ## Already put petrol in a diesel in Uttoxeter? Then, there is only a short order of things. Starting it is out, and so is switching on the ignition. If you're still at the forecourt — Tesco or anywhere else — ask the attendants to help you push the car clear of the petrol pump. Next, 0333 366 0103. We'll ask what got in, roughly how much, and if it's been run. AdBlue, not petrol? Then tell us. Corrosion and deposits, not lost lubrication, make it a separate fault — Uttoxeter has a page just for it. ## What makes one Uttoxeter petrol in a diesel job cost more than the next An honest single price does not exist here: four scenarios, four separate jobs. What moves the cost is mostly which of them you're in. Where the car is counts too, and whether our van can safely get to it, after the share of petrol to what your tank takes. Three questions come first, before any quote, instead of after — what got in, how much, has it run — and that is the reason. Given the replies, there is a straight figure rather than a range. ## About Uttoxeter Uttoxeter is a town in Staffordshire, situated on the River Dove at an elevation of around 92 metres.
