Here Is What Happens Stop, and leave the engine off — not on, and not for a second to shift it. Cleared and purged, right where it is: that is generally all an unrun diesel with petrol in it takes. Whether it stays that simple rests on the minutes to come more than on everything else. What follows is the order from this point, wherever around Mytholmes you are. ## Petrol in a diesel? What to do in minute one Do these before anything else, in this sequence. - Priming the fuel system draws petrol from your tank towards the components it damages, and turning the ignition on can be enough to do that. So the keys get taken out, and your ignition remains off altogether. - Don't top it up with diesel. Adding diesel removes nothing. You end up with a fuller tank of the same mixture. - Being seen comes first near moving traffic: switch the hazard lights on, and only then think about anything else. - Off the petrol pump by hand. At a forecourt, ask the attendants to help you push the vehicle away from the petrol pump. Don't fire it up to shift it, however short the distance. - The first question you will be asked is which fuel went in and about how much — and your receipt says both. Keep it. On the M606, under 10 miles from Mytholmes, the next exit is the spot to come off; anywhere, the first safe place to stop. Do not push on to the services. Then go back to step one. ## Mytholmes fuel drain: has the motor run yet, or not? From this stage on, everything comes down to a single answer. If the motor has not run at all: - Only that tank has petrol in it so far. - Where your car stands is normally where this work happens: a drain, then a flush. - No position is better, and it is why the first step matters so much. Engine run, even for a moment? - Petrol has been pulled from the tank, past the fuel filter and into the fuel lines. - Your high-pressure pump and your injectors get it on a bigger run. - The job expands with the mileage — lines rinsed, filter dealt with, sometimes more. Petrol doesn't lubricate. Diesel does, oiling your pump and injectors as it passes through, which is why the line sits where it does. Petrol sitting in a tank damages nothing. As soon as it is pumped, petrol starts grinding whatever moves it. ## Before you call about petrol in a diesel around Mytholmes: what our engineers need Prepare a little, and the technician finds you instead of circling. - Where you are. A postcode starting BD22 7 is the ideal place to start. - The road or the car park. A road name helps — High Oak Garth, or wherever you have stopped. - Name a car park by what it serves — the one outside The Co-operative Food, for example — and it is far easier to find. - That it is a diesel, plus the make and model of your car. - What went in. Petrol, or AdBlue. AdBlue is a different job with its own page for Mytholmes, so say which. - Roughly how much — in litres from the receipt, or by how long the nozzle stayed in. - If it has run, how far plus how heavily — and if it's run at all. - Hire or company car? Some agreements want the owner's authorisation for the work, and sorting it before our engineers arrive is quicker than afterwards. Phone 0333 366 0103 next. Writing to works too if it can wait, with your car parked at home, going nowhere. ## Whilst you wait for a fuel drain in Mytholmes Help, however well meant, is the thing that does the harm while you wait. So hold to these. - Stay with your car if it is safe where it is — but if it has stopped somewhere unsafe, you come first: away from the traffic, waiting apart from it. - Not to roll it a couple of yards, not to check it is all right, not as a passer-by's favour: no one starts it. - No additives. Two-stroke oil, injector cleaner, anything from the boot — none of it gets that petrol back out. - No home-made emptying. Siphoning petrol into a can by the roadside is risky, and it leaves your fuel that has already gone beyond your tank. - Even the radio or the windows are not worth turning your ignition on for. ## The fuel drain, step by step, after our van gets there - Our price comes after three questions, not before them — what got in, how much, and if it's run — because the replies set this job. - Then your tank is cleared, and the polluted fuel is taken out. - If it ran, your lines are holding petrol that has moved beyond your tank — so they're rinsed. - Where the vehicle has a workable filter, it's replaced; otherwise, cleared. - Clean diesel goes in, then your system is primed. - First start on clean diesel. Once priming is done, your engine is fired up and we confirm that it runs correctly. Till it runs on new diesel, our technicians stay with it. Lasting damage is very uncommon if it has been caught soon, so the car can go right back to normal driving. ## Back on the road in Mytholmes after the fuel drain - Drive normally. There's nothing unusual to do after it's been started on clean fuel. - Pull over and call us back if anything seems wrong early on — a light on the dash, smoke from the exhaust, an idle that runs rough, or a throttle with a dead spot. - Hold on to your paperwork. A hire company, a fleet manager or an insurer may ask what was done. - Check the label on the pump next time, not the colour of the handle. ## About Mytholmes Mytholmes is a locality situated on the riverside in West Yorkshire, with an elevation of 195 metres and a population of around 1457 residents.
