Pause there. Drained then purged, right where it is: that is generally all an unrun diesel with petrol in it needs. Whether it remains that simple rests on the minutes ahead far more than on everything else. What follows is the sequence from this point, wherever in Costhorpe you are. ## Motor off: minute one with petrol in a diesel In this sequence, all before anything else: - Pull your keys out. Even your ignition on its own can prime your fuel system, drawing petrol out of the tank to exactly the components it harms, and so leave the car alone entirely. - No diesel on top. More fuel in takes away none of the petrol — it only leaves you with more of the same blend. - Hazards on. If you're anywhere close to moving traffic, make your car easy to see before you do anything else. - Off the petrol pump by hand. At a forecourt, ask the attendants to help you roll the vehicle clear of the pump. Do not crank it to move it, however short the distance. - Keep the till receipt. It shows which fuel got in plus roughly how much, which is the first thing we will ask. Realised on the move? Get off at the next junction if you are on the Doncaster By-Pass, under 3 miles from Costhorpe, and pull over somewhere sensible — not at the services farther on. Step one comes after that. ## Each Costhorpe fuel drain starts here: has the motor run? What comes next rests on one answer, and only one. Not run, not even once: - Nowhere but that tank: that's where that petrol yet is. - The work is a drain and a flush, usually done where the car is. - No place is better, and it is why the first step counts so much. Engine run, however briefly? - From the tank, past your filter, into your lines: that is how far the petrol has travelled. - Run it farther and the petrol reaches your injectors, having gone through your pump first. - Flushing the lines, your filter dealt with, and sometimes more: the job grows as the miles does. Diesel keeps the high-pressure pump and your injectors protected as it goes through them. Petrol gives them nothing, and that is why the line is drawn there. A tank of petrol, left alone, hurts nothing. Petrol being pumped is wearing the parts that move the car. ## Calling about petrol in a diesel from Costhorpe: what to have ready Prepare a little, and the technician finds you rather than circling. - Where you are. A postcode beginning S81 9 is the best place to start. - A road name helps: Northumberland Avenue, say, or whichever street you have stopped in. A car park works too. - Or the nearest landmark. A car park is quicker to find by what it serves, such as the one at Asda. - Make and model of your vehicle, and the fact it's a diesel. - What got in. Petrol, or AdBlue. AdBlue is a separate job with its own page for Costhorpe, so say which. - How long the nozzle was in, or the litres on the receipt — whichever gives us how much. - Whether it's run. Then if it has, how far and how heavily. - Whose motor it is. Some hire or company agreements want the owner to authorise this work, and that is easier settled before our technicians arrive than after. Then ring 0333 366 0103. If it can wait — your car is at home with going nowhere — works as well. ## Waiting for a fuel drain in Costhorpe: what to do Hold to these: well-meant help causes the damage during the wait. - Safety before the car. If it has stopped somewhere exposed, get yourself clear of the traffic then wait away from it. If it is safe where it stands, stay with it. - A helpful passer-by doesn't crank it. Nor does anyone checking it still does the trick, or moving it a few yards. - Something from the boot, oil meant for two-strokes or injector cleaner: no additive removes the petrol. - A home-made drain leaves your fuel already gone beyond your tank, and siphoning petrol by the road is hazardous besides. - Not for the radio, not for the windows: your ignition remains off. ## Van arrived? Your fuel drain, one stage at a time - Three questions. What got in, how much, and whether it's run. Those answers set this job, which is why our quote comes after them but not before. - Out of the tank comes the contaminated blend: that tank is emptied. - Petrol that has moved beyond your tank travels in the lines once it ran, and your lines are purged to shift it. - Then the fuel filter: changed where there's a workable one, cleared where there's not. - The system is primed with fresh diesel. - The first start on clean diesel. Once priming is finished, your engine is fired up and our engineers make sure that it runs properly. Our engineers remain until it is running on fresh diesel. If it has been caught early, permanent damage is very unusual, and your car goes back to normal driving at once. ## Back on the road around Costhorpe after your fuel drain - Drive normally. There's nothing special to do after it has been started on fresh fuel. - Pull over and ring us back if anything looks wrong early on — a light on your dash, smoke from the exhaust, an idle that runs rough, or a throttle with a dead spot. - The work may come up later with a hire company, an insurer or a fleet manager. Keep your paperwork. - The handle's colour is not the thing to go by next time — the label on the pump is. ## About Costhorpe and where it is Costhorpe is a suburban area in Nottinghamshire, situated inland at an elevation of 32 metres, and is located near several nearby places including Carlton in Lindrick, North Carlton, and Langold.
