Stop; leave it off. Cleared then rinsed, just where it is: that's usually all an unrun diesel with petrol in it takes. Whether it stays that straightforward depends on the minutes ahead far more than on everything else. Wherever you are in Wrentham, this is the order things run from here. ## Minute one: petrol in a diesel, engine off Before anything else, the following — in this order. - Pull your keys out. Even your ignition on its own can prime the fuel system, pulling petrol out of your tank to precisely the parts it harms, and so keep the car alone entirely. - No diesel on top. More fuel in removes none of the petrol — it only makes you with more of the same blend. - Hazard lights on. If you're anywhere near moving traffic, make the vehicle easy to see before you do anything else. - By hand, not on the motor: that's how it comes off the pump. Ask the forecourt staff to help you push, whatever the mileage. - Which fuel, and roughly how much? Your receipt replies that, and that's where our questions start. Do not throw it away. Still on the move when you realised? Come off the M11 at the next exit if that's where you are, over 50 miles from Wrentham, and stop somewhere sensible rather than pushing on to the services. Then start at stage one. ## Wrentham fuel drain: has your engine run yet, or not? One answer is what everything after this stage rests on. Not run, not even briefly: - The petrol sits in your tank, and only there. - The job is a drain and a flush, normally done where your car is. - No position is better, and it's why the first step matters so much. Engine run, even briefly? - The lines and your filter already carry petrol drawn out of your tank. - Run it farther and the petrol reaches the injectors, having gone through your fuel pump first. - Flushing your lines, the filter dealt with, and sometimes more: this job grows as the mileage does. Diesel keeps your high-pressure pump and the fuel injectors lubricated as it runs through them. Petrol gives them nothing, and that's why the line is drawn there. A tank of petrol, left alone, hurts nothing. Move the petrol, though, and it wears the very parts that move it. ## Wrentham, petrol in a diesel: have these prepared before you call A van that circles against a van that finds you: a little planning is what separates them. - Where you are. A postcode beginning NR34 7 is the best start. - Wherever you have parked, the road's name helps — whether that's Chapel Road or somewhere else — and so does the name of a car park. - Car parks are found more easily by what they serve: say the one at Co-op Food, and it is simple. - The vehicle. Make, model, and that it's a diesel. - Say which was put in — petrol or AdBlue — since AdBlue is a different job, with a page of its own for Wrentham. - How much. Litres from the receipt, or how long the nozzle was in. - Whether it's run. Then if it has, how far and how hard. - Whose vehicle it is. Some hire and company agreements want the owner to approve the work, and that's quicker settled before our technicians arrive than after. Next, 0333 366 0103. Not urgent, your car parked at home with nowhere to be? Then will do too. ## While you wait for a fuel drain in Wrentham Stick to these: kindly meant help does the harm during the wait. - Wait with the car if it's safe where it is — but if it has stopped somewhere exposed, you come first: away from the traffic, waiting apart from it. - A kind passer-by does not fire it up. Nor does anyone wanting to check it still does the trick, or moving it a few yards. - No additives. Two-stroke oil, injector cleaner, something from your boot — none of it takes the petrol back out. - A DIY drain misses your fuel already gone beyond your tank, and siphoning petrol by the road is dangerous besides. - Even the radio or the windows are not worth switching the ignition on for. ## Van arrived? Your fuel drain, one step at a time - Three queries. What was put in, how much, and if it's run. The replies decide the job, which is why the quote comes after them but not before. - Out of your tank comes the contaminated mixture: your tank is emptied. - If it ran, the lines are carrying petrol that has shifted beyond your tank — so they are flushed. - Cleared, or swapped if the vehicle has a serviceable one: the filter is sorted next. - Fresh diesel in, and the system primed. - First start on fresh diesel. When bleeding is finished, the engine is fired up and our technicians make sure that it runs smoothly. The car has clean diesel running through it before we head off. Your car goes back to normal use straight away, and lasting damage is very rare if it has been spotted soon. ## Wrentham, after your fuel drain: back on the road - Drive normally. There is nothing special to do after it's been started on clean fuel. - Pull over and ring us back if anything seems wrong early on — a light on the dash, smoke from the exhaust, an idle that is lumpy, 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. Keep it. - Check the label on the pump next time, not the colour of its handle. ## About Wrentham Wrentham is a small village on the Suffolk coast, situated near the Norfolk border at an elevation of around 8 metres.
