Not started? Then less worried than you likely are. Petrol resting in a diesel tank does nothing to the engine till something pulls it through your fuel system — the ignition priming the pump, the starter, or the drive on its own. So the honest answer to the first query anyone in Burton Leonard asks, "have I ruined it?", is generally no. Keep it that way: leave your motor off and call Petrol in Diesel. What petrol really does to a diesel, how to gauge how far it's travelled, and how to stop it from happening a second time: that is the remainder of this page. ## What petrol in a diesel does to your engine Two jobs fall to diesel on its journey through a motor. It protects to begin with, and only then does it burn. What keeps the surfaces inside the high-pressure pump and the injectors from wearing against each other is your diesel flowing through them — they're designed to very fine tolerances. Petrol handles the first job badly and the second not at all. Being less viscous than diesel, petrol strips out the lubrication a fuel system needs, leaving a pump running on the blend to wear itself. It's equally made to resist igniting under compression — the reverse of what a diesel needs — which is where you get the knocking. The shape of the problem is clear once 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. A pump that has been labouring on that petrol is the beginning of a mechanical one, and whatever a worn pump sheds moves on with your fuel to the fuel injectors further on. ## How serious is petrol in a diesel? Four scenarios our engineers see in Burton Leonard Filled but not once started — as good as it gets. That petrol is inside that tank and just that tank, and the task is a drain and a flush where the car sits. This is the one situation that can only truly occur at a forecourt, since anywhere else your car has been driven to get there. The ignition turned on, or a short start. Petrol has come out of the tank and reached your filter and your lines, since your system has been primed. That is generally still an easy job — a drain, a flush, and the fuel filter seen to. Your pump now worked a few miles on thinned fuel — that's what driving the car meant. Tank, lines, filter, then clean fuel run through the entire system: that is the work, and the way your car was driven matters as much as the miles. The school run to Burton Leonard Church of England Primary School is one thing. Very different again: a trip to Ripon, under 5 miles away, or any mileage on the A1(M), under 5 miles from Burton Leonard, where your engine never stopped running hard. It protested, and only then stopped: smoke, clattering, a throttle gone soft, an idle gone ragged. The engine is telling you your fuel is no longer behaving like diesel. Pull up where you are — on the verge on Station Lane, at the kerb, down a side road — and don't move it again. Permanent damage is very unusual if a car is stopped early, and the fuel drain and flush that still come first take care of it. ## Burton Leonard people and that petrol in a diesel stories they hear It will not be fine. The myth: "Fill it the rest of the way with diesel and it will be." Topping up takes out nothing; it gives you a bigger tank of the same mix. That guidance presumes a diesel fuel system handles petrol by percentage. It does not. If anything, the opposite is true. Myth: "A newer diesel can cope with a bit of petrol." At higher pressure, through smaller components: that is how a newer diesel handles its fuel, so the protection counts for more, not less. One myth that catches motorists out: if it starts and drives, it must be unharmed. The motorist of a petrol engine fed diesel normally stops, since it will not run, and the damage stops there. Feed petrol to a diesel and it usually starts, ticks over and drives away like nothing happened — all while its pump is wearing. Running does not mean fine. Myth: "Add some two-stroke oil and drive it home." It's an old fix for a different problem. None of what petrol weakened gets put back by it — and later, the tank still contains the petrol. "Drain it yourself and you are sorted" — a myth, because after it has been running some petrol lies in your filter and lines, ready to go straight back through the pump on your next start. It is also truly hazardous to drain petrol into a can at the roadside. ## How it happens: petrol in a diesel It is rarely carelessness, and nobody does it on purpose. A diesel nozzle mostly will not go into a petrol vehicle, yet the narrower petrol nozzle goes into the filler of a diesel almost without resistance — so forecourts make this one error simple, and just in that direction. It happens when habit and your car stop matching. A new car, a hire car or a courtesy car. One petrol and one diesel on the driveway of the same household. A forecourt you know, but with its pumps laid out differently. A rushed fill on the way to Knaresborough with a train to catch. Years of petrol cars behind you, a diesel Volkswagen Golf in front of you at the forecourt for its first tank — that is when. Add rain, a phone call or a back seat full of kids, and your hand does what it has always done. ## Preventing petrol in a diesel next time you fill up in Burton Leonard - Check the petrol pump, not the colour. In the UK unleaded handles are generally green and diesel black, yet not on each forecourt. The label is what counts. - Inspect the filler flap. Plenty of motors state the fuel inside the flap or on the cap. Look at it on the first fill in a vehicle you do not know. - A coloured fob or a sticker on your diesel's key achieves more than any amount of intending to remember, in a household with one of each. - It sounds silly and it works: on the first fill in a new or hired car, say "diesel" out loud before you lift the nozzle off the pump. - Whilst you are thinking about something else, this is an easy mistake to make — so put the phone away. - A misfuel inhibitor helps, up to a point. Some diesels have a filler designed to block a petrol nozzle, and add-on devices exist for cars without one. They are a safety net, not a reason to stop reading the petrol pump. - Less petrol makes a weaker mix, so stop the moment you notice — though remembering that the next stage is unchanged. It's still not to crank it. ## Petrol already in a diesel around Burton Leonard? Start here Then the order of things is brief. Starting it is out, and so is turning on the ignition. The attendants on the forecourt — whether at Esso itself or wherever you filled up — will usually help push it clear of the petrol pump if you ask. What went in, about how much, and whether it's run: tell us that when you ring 0333 366 0103. Say so if it was AdBlue rather than petrol: it's a separate fault, with its own page for Burton Leonard, since AdBlue brings corrosion and deposits rather than lost lubrication. ## Why one petrol in a diesel job in Burton Leonard costs more than another The four situations above are four separate jobs, so no single price for this would be fair. What shifts the cost is mostly which of them you're in. Two things come after that: the petrol that was put in as a proportion of what your tank holds, then the place the car is in and whether a technician can reach it safely. Before any quote, not after, we ask three questions: your fuel that went in, the quantity, and whether it's run. That is why. Those answers are what turn a range into one firm number. ## About Burton Leonard itself Burton Leonard is a small village in North Yorkshire, situated approximately 4.7 miles from Ripon and 186.1 miles from London.
