Engine off. Keep the car that way — no moment on, no shifting it anywhere. Has not been run? Then petrol in a diesel tends to be a simple drain-and-flush job wherever your vehicle has stopped — and nothing settles that more than these next few minutes do. Here is the order of things from now, wherever you are around Harden. ## Minute one: petrol in a diesel, engine off In this order, and before everything else: - Priming your fuel system pulls petrol from the tank toward the parts it harms, and switching the ignition on can be enough to do that. So your keys get taken out, and your ignition stays off altogether. - No diesel on top. More fuel in takes away none of the petrol — it just makes you with more of the same blend. - Near moving traffic? Then the hazards go on before everything else, so the car is easy to spot. - However short the distance, starting it to shift it is the mistake. On a forecourt, push it away from the pump by hand instead, then ask the staff to help. - Hold on to your receipt. It says which fuel got in plus roughly how much, which is the first thing we'll ask. On the M62, under 10 miles from Harden, the next junction is the place to leave it; anywhere, the first sensible spot to stop. Don't press on to the services. Then go back to stage one. ## Has it run yet? The fork in each Harden fuel drain Everything after this point rests on one answer. If your engine has not run at all: - No place but that tank: that's where the petrol yet is. - Normally it's emptied and cleaned right where your car stands. - Stage one matters for precisely this reason: it is the best place to be in. Engine run, however briefly? - The lines and your filter already hold petrol drawn from that tank. - On a bigger run it has reached the high-pressure pump and the injectors. - Flushing the lines, the fuel filter seen to, and sometimes more: the job grows as the miles does. Diesel keeps the high-pressure pump and the injectors oiled as it runs through them. Petrol offers them nothing, and that's why the line is drawn there. Nothing is damaged by petrol that is only waiting in a tank. As soon as it's pumped, petrol starts wearing down whatever moves it. ## What to have ready when you call about petrol in a diesel from Harden Whether the technician circles or finds you depends on a little planning. - HD9 2 plus the rest of the postcode makes the ideal way to start telling us where you are. - Wherever you have parked, the road's name helps — whether that is Dunford Road or somewhere else — and so does the name of a car park. - What a car park serves is the easiest way to find it, so mention the landmark — such as the one at Co-op Food. - The make and model of the car, and the fact it's a diesel. - Petrol or AdBlue? Tell us which. They are different jobs, and AdBlue has its own Harden page. - About how much — in litres from the receipt, or by how long the nozzle stayed in. - Whether it has run. Then if it has, how far and how heavily. - Whose car it is. Some hire or company agreements want the owner to authorise this work, and that's easier settled before our engineers get there than after. Call 0333 366 0103 once you have got that together — or, if the car is at home, going nowhere, use . ## The wait for a Harden fuel drain, and what to do in it Stick to these: kindly meant help does the harm during the wait. - Where the car has stopped settles where you wait. Somewhere exposed: away from it, away from the traffic. Safe: with it. Either way, safety before the car. - Nobody — however helpful — starts it, whether to see if it runs or to shift the vehicle a short way. - Additives remain in the boot. Injector cleaner and two-stroke oil take none of that petrol out again. - No home-made draining. Siphoning petrol into a can by the kerbside is risky, and it leaves your fuel that has by now gone beyond the tank. - Even the radio or your windows are not worth turning the ignition on for. ## The fuel drain, step by step, once the van arrives - First, three questions: which fuel went in, the quantity, and has it run? Those answers decide this job, and so our quote follows them. - Then your tank is cleared, so the tainted fuel comes out. - The lines are purged. If it ran, that petrol has shifted beyond that tank, and the lines are holding it. - Cleared, or swapped if the car has a workable one: the filter is dealt with next. - Fresh diesel in, and your system primed. - Starting the car. When the fuel system is primed with clean diesel, our technicians start the engine and confirm it runs correctly. Our technicians stay until it is running on new diesel. The vehicle returns to normal use right away, and long-term damage is very rare when it has been noticed early. ## After the fuel drain: back on the road in Harden - Drive normally. There's nothing special to do after it has been started on clean fuel. - Pull over and call us back if anything seems wrong early on — a light on your dash, smoke from your exhaust, an idle that runs rough, or a throttle with a dead spot. - The work may matter later with a hire firm, an insurer or a fleet manager. Hold on to your paperwork. - Read the label on the pump next time, not the colour of its handle. ## About Harden, for a moment Harden is a small hamlet situated on the edge of a lake in South Yorkshire, with a elevation of 298 metres.
