Stop; leave the car off. Petrol in a diesel that has not been run is normally a drain and a flush, done right where your car sits, and what you do in the coming few minutes settles that more than anything else. Here is the sequence of things from now, anywhere you are around Mytholmroyd. ## Petrol in a diesel, engine off — the first minute Do these before anything else, in this order. - The keys out of the ignition. Switching the ignition on can be enough to prime your fuel system, and priming draws petrol out of the tank towards the parts it damages. Keep the vehicle off altogether. - Don't top it up with diesel. Adding diesel takes out nothing. You are left with a fuller tank of the same mix. - Close to passing traffic? Then the hazard lights come on before everything else, so the car is easy to see. - However short the distance, starting it to shift it is the mistake. At a forecourt, roll the car away from the pump by hand instead, then ask the staff to help. - Keep the receipt. It says which fuel went in and about how much, which is the first thing we'll ask. Noticed on the move? Get off at the next exit if you are on the M62, under 10 miles from Mytholmroyd, and pull over somewhere safe — not at the services farther on. Step one comes after that. ## Mytholmroyd fuel drain: has the engine run yet, or not? One answer is what everything after this stage depends on. If it has not once been started: - Nowhere but your tank: that's where that petrol yet is. - Where the car stands is usually where the work happens: a drain, then a flush. - No position is better, and it's why the first step matters so much. If it has been started, even for a moment: - Out of your tank, through your filter, into your lines: that's how far that petrol has travelled. - On a bigger run it has got to the high-pressure pump and your injectors. - The farther it went, the bigger the job — the fuel lines, your filter, and now and then more besides. Why the line falls there: diesel lubricates the high-pressure pump and the injectors as it flows through them, and petrol does not. In the tank, sitting still, petrol harms nothing. Once it's pumped, petrol begins wearing whatever moves it. ## Before you call about petrol in a diesel around Mytholmroyd: what our engineers need A van that circles versus a van that finds you: a little planning is what separates them. - Where you have stopped. A postcode starting HX7 5 is the ideal place to start. - The street or the car park. A road name helps — Burnley Road, or wherever you have pulled up. - What a car park serves is the easiest way to find it, and so mention the landmark — like the one outside Pennine Provisions. - The vehicle. Make, model, plus that it's a diesel. - Tell us which went in — petrol or AdBlue — since AdBlue is a separate job, with a page of its own for Mytholmroyd. - How long the nozzle was in, or the litres on your receipt — either tells us how much. - Whether it's run. Then if it has, how far and how hard. - Hire or company car? Some contracts need the owner's authorisation for the work, and getting it before we arrive is quicker than after. Then call 0333 366 0103. If it can wait — your car is at home and going nowhere — does the trick too. ## Waiting for a fuel drain around Mytholmroyd: what to do The wait is where well-meant help does the harm. Stick to these. - Stay with the car if it is safe where it is — but if it has stopped somewhere exposed, you come first: away from the traffic, waiting apart from it. - Nobody starts it. Not a passer-by being kind, not to check it is all right, not to roll the car a couple of yards. - Something from your boot, oil made for two-strokes or injector cleaner: no additive removes the petrol. - A home-made drain leaves the fuel already gone beyond the tank, and siphoning petrol by the road is hazardous besides. - Not for the radio, not for the windows: your ignition stays off. ## When the van arrives: your fuel drain, step by step - Three queries. What went in, how much, and whether it has run. The answers set the job, which is why the quote comes after them and not before. - Next your tank is cleared, and the tainted fuel comes out. - The lines are cleaned. If it ran, that petrol has moved beyond your tank, and your lines are holding it. - Your filter is seen to. Cleared, or changed where the vehicle has a usable one. - Fresh diesel in, and the system primed. - First start on clean diesel. Once priming is done, the engine is fired up and we check that it runs properly. Your car has fresh diesel running through it before our technicians go. Your car goes back to normal driving straight away, and permanent damage is very unusual if it has been noticed early. ## Back on the road around Mytholmroyd after the fuel drain - Started on new diesel, it needs nothing unusual of you. Just drive normally. - Pull over and ring 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. - Your paperwork answers the question a rental company, fleet manager or insurer may ask: what work was carried out. File it. - Check the label on the petrol pump next time, not the colour of its handle. ## About Mytholmroyd and where it is Mytholmroyd is a village in West Yorkshire, situated on the banks of the River Calder at an elevation of 94 metres.
