If it hasn't been started, worry far less than you likely are. Till your ignition primes the pump, your starter cranks, or the vehicle is driven, petrol in a diesel tank simply rests there and does nothing. Which makes the honest reply to that first Condorrat question — "have I wrecked it?" — normally no. Keep it like that: leave your engine off then phone Petrol in Diesel. 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. ## What petrol in a diesel does to your engine Two jobs fall to diesel on its journey through a motor. It lubricates to begin with, and after that does it burn. The high-pressure pump and the fuel injectors are built to extremely fine gaps, and the diesel passing through them is what keeps those surfaces from wearing down against each other. The second job petrol does not do at all, and the first it does badly. A pump running on a petrol mixture is wearing itself out, because petrol is runnier than diesel and strips out the protection your fuel system relies on. Petrol is also made to resist igniting under compression — the reverse of what a diesel wants from its fuel — and that's where any knocking comes. Taken together, they show the shape the issue has. The damage is done by circulation, not by contact. Any tank with petrol in it is a fuel problem. After your pump has been labouring on that petrol, a mechanical problem has started: anything shed by a pump that's wearing is carried onward to your injectors with the fuel. ## How bad is petrol in a diesel? Four situations our technicians see in Condorrat Fuelled but never started — as good as it gets. Being at a forecourt is what makes this the case: elsewhere, the car has been driven there to begin with. With that petrol held inside that tank alone, it's cleared and flushed on the spot, and nothing more is needed. Started for a moment, or only your ignition on. The fuel system has been primed, so petrol has left your tank and got to your filter and the lines. That's usually still an easy job — a drain, a flush, and the fuel filter seen to. Those few miles on the road were your pump labouring on fuel diluted by petrol the whole way. The work is your tank, the lines, your filter and fresh fuel through the entire system, and how hard the vehicle was driven counts as much as how far. Short trips, like the school run to the local primary school, are one matter. A run as far as Glasgow, under 10 miles away, is a very different job. So is any mileage on the M80, under a mile from Condorrat, where your engine has been working hard throughout. It protested, and only then stopped: smoke, clattering, a throttle gone soft, an idle gone lumpy. What you are hearing is the engine reporting fuel that no longer acts like diesel. Stop where you are — on the verge on Maree Drive, at the kerb, down a side road — and don't move it again. The fuel drain and flush-through still come first, and they sort it out: when a car is stopped quickly, permanent damage is very rare. ## Petrol in a diesel myths Condorrat drivers hear Myth: topping up to full with diesel makes it fine. It does not. Nothing is removed when you top up — the tank just holds more of the same mixture. Percentage isn't how a diesel fuel system tolerates petrol, whatever that advice supposes. Myth: "A modern diesel can cope with a bit of petrol." If anything, the reverse. Finer parts and higher pressure are how a current diesel runs its fuel, and that makes the protection count more, not less. "It starts, it drives, so there is no harm" — the myth that trips up more people than any other. Feed diesel to a petrol motor and it generally won't run, and so the motorist stops — and the damage stops with them. Nothing seems to have happened when a diesel fed petrol fires up, ticks over and drives away, as it usually does; meanwhile your pump wears. A running engine does not mean fine. Myth: "Add some two-stroke oil and drive the car home." It is an outdated fix for a distinct issue. None of what petrol diluted is put back by it — and later, your tank still holds that petrol. Myth: "Drain the tank yourself and you're sorted." Once the engine has run, some of the petrol is no longer in your tank: it's in the filter and your lines, and it goes straight back through your pump on your next start. It is also truly risky to drain petrol into a can at the kerbside. ## How petrol ends up: petrol in a diesel It's seldom carelessness, and no one does it on purpose. One way only, since of the nozzles: the slimmer petrol one slips inside a diesel filler with almost no resistance, while the diesel one mostly won't fit a petrol motor. That's how the forecourt makes it simple. It takes place when habit and your car stop matching. Hire cars, courtesy cars, and vehicles that are new to you. One petrol and one diesel on the driveway of the same household. The pumps in a different order on a familiar forecourt. A hurried fill on the way to Greenfaulds with a train to catch. Precisely the moment it takes place: after years of driving petrol, a driver fills a diesel Renault Megane for the first time. Your hand does what it has always done once you add rain, a phone call or a back seat full of kids. ## Condorrat motorists: how to avoid petrol in a diesel next time - Check the petrol pump, not the colour. In the UK unleaded handles are normally green and diesel black, yet not on each forecourt. The label is what counts. - Many cars state the fuel inside your filler flap or on the cap, and so check there on the first fill in any car you don't know. - Good intentions do less than a sticker or a fob in a bright colour on your diesel's key when a home has one of each. So label it. - "Diesel", aloud, before you lift the nozzle — every time a new or hired car needs its first tank. It seems daft. It works. - Mistakes like this are straightforward to make whilst your mind is on something else, so your phone goes away. - Up to a point, a misfuel inhibitor helps: some diesels have a filler built to block a petrol nozzle, and aftermarket devices are available for the rest. Count it as a backstop, then keep reading the pump. - Noticing it mid-fill? Stop at once. A thinner blend follows from less petrol in the tank, yet the next step remains the same: do not start the car. ## Condorrat: already put petrol in a diesel? Short and simple, then, is the order of things. Do not switch the ignition on, and do not crank it. Yet at the forecourt, at BP or anywhere else? Ask the attendants to help you roll it clear of the petrol pump. What got in, about how much, and whether it has run: tell us those when you phone 0333 366 0103. Say so if it was AdBlue instead of petrol: it is a separate fault, with its own page for Condorrat, because AdBlue brings corrosion and deposits rather than lost lubrication. ## Why one petrol in a diesel job around Condorrat costs more than another Four separate tasks sit behind the four scenarios above — which is why there is no fair single price. Chiefly, the cost moves with which one you're in. Two things come after that: the petrol that went in as a share of what that tank holds, then the spot the car is in and whether a van can get to it safely. What was put in, how much, and whether it has run — three queries we ask before costing, not after, for precisely that reason. The answers change a range into a straight figure. ## About Condorrat itself Condorrat is a suburban area situated on the riverside in North Lanarkshire, with a mix of terraced housing and local amenities.
