Pause there. Petrol in a diesel that hasn't been run is generally a drain plus a flush, done where the car stands, and what happens in the coming few minutes determines that more than anything else. Anywhere you happen to be in New Inn, here is how things go from here. ## Petrol in a diesel? What to do in minute one Go through the following in order, first. - Take the keys out. Even your ignition on its own can prime your fuel system, pulling petrol out of your tank to precisely the parts it damages, so leave it off wholly. - Topping up with diesel seems like it dilutes the trouble. It doesn't: nothing gets out, and the tank simply holds more of the same. - Close to passing traffic? Then the hazards go on before anything else, and so the vehicle is simple to spot. - The attendants will normally help you push it clear of the petrol pump. Ask, then roll it by hand — never under the motor, even for a few yards. - The first thing we will ask is which fuel you put in and about how much — and your receipt shows both. Keep it. Realised on the move? Get off at the next junction if you are on the M4, under 10 miles from New Inn, and pull over somewhere sensible — not at the services further on. Stage one comes after that. ## New Inn fuel drain: has the motor run yet, or not? One answer is what everything after this point depends on. If it has not once been started: - The petrol is still in your tank and nowhere else. - Where the vehicle sits is usually where this work is done: a drain, then a flush. - This, here, is the best spot to be in, and the whole reason step one counts. Motor run, however briefly? - From your tank, through the filter, into the lines: that is how far the petrol has got. - The high-pressure fuel pump as well as the fuel injectors see it too on a longer run. - The job grows with the distance — lines rinsed, filter sorted, occasionally more. That line falls there since diesel lubricates the high-pressure pump and the fuel injectors on its way through them — and petrol doesn't. A tank of petrol, left alone, damages nothing. Petrol being pumped is grinding down the parts that move the car. ## Before you call about petrol in a diesel around New Inn: what our engineers need Get ready a little, and the technician finds you rather than circling. - Your whereabouts: a postcode starting NP4 0 serves best. - The street or the car park. A road name helps — Golf Road, or wherever you have stopped. - Car parks are located more easily by what they serve: say the one at ALDI, and it is straightforward. - That it is a diesel, plus the make and model of your car. - Tell us which got in — petrol or AdBlue — because AdBlue is a different job, with a page of its own for New Inn. - How much. Litres from the receipt, or how long the nozzle was in. - The miles it did, and how heavily, if it ran at all. - Whose motor it is. Some hire and company agreements want the owner to authorise this work, and that's easier settled before our engineers get there than after. Next, 0333 366 0103. Not urgent, the vehicle left at home with nowhere to be? Then works as well. ## The wait for a New Inn fuel drain, and what to do in it Hold to these: kindly meant help does the harm during the wait. - Your safety comes before your car. Somewhere exposed? Get clear of the traffic and wait away from it. Fine where it stands? Stay with 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. - None of it gets that petrol back out — not two-stroke oil, not injector cleaner, not something from your boot. So no additives. - Siphoning petrol into a can by the kerbside is hazardous — and it still leaves whatever fuel has already gone beyond your tank. Don't drain it yourself. - Not for the radio, not for your windows: your ignition remains off. ## Van arrived? Your fuel drain, one step at a time - Fuel, quantity, whether it's run: the answers decide this job, and that's why you get a price after them instead of before. - Out of that tank comes the contaminated blend: that tank is cleared. - The lines are cleaned. If it ran, the petrol has shifted beyond the tank, and your lines are carrying it. - Then the filter: swapped where there's a serviceable one, cleared where there is not. - Fresh diesel in, and the system primed. - Starting it. After the system is bled with clean diesel, our technicians fire it up and check it runs correctly. Until it runs on clean diesel, we remain with it. When it has been spotted quickly, long-term damage is very unusual, and the vehicle goes back to normal driving right away. ## Back on the road around New Inn after your fuel drain - Started on fresh diesel, it needs nothing special of you. Just drive normally. - Watch the first miles. A warning light, smoke, a rough idle or a flat spot under the throttle means pull over then call us back. - An insurer, a fleet manager or a hire company may ask what was carried out, so hold on to the documents. - Next time, read the pump. The label, not the colour of the handle. ## About New Inn itself New Inn is a suburban area in Torfaen, situated on the riverside at an elevation of 114 metres, with semi-detached housing being the predominant type of accommodation.
