Stop there. Has not been run? Then petrol in a diesel will usually be a simple drain-and-flush job wherever your car has stopped — and nothing decides that as much as these next few minutes do. Below is the order from this point, anywhere around Cusworth you are. ## Engine off: minute one with petrol in a diesel Go through these in sequence, first. - Priming the system pulls petrol from the tank towards the components it harms, and turning the ignition on can be all it takes to do that. So your keys get taken out, and the ignition remains off completely. - No diesel on top. More fuel in takes away none of that petrol — it only makes you with more of the same blend. - Visibility comes before the rest beside moving traffic: put the hazard lights on, and only then deal with anything else. - The attendants will generally help you roll it away from the pump. Let them, then roll it by hand — never under the motor, even for a couple of yards. - Hold on to your receipt: the grade and the rough amount are printed on it, and they are what we ask for first. Still on the move when you realised? Come off the A1(M) at the next exit if that is where you are, under a mile from Cusworth, and stop somewhere safe rather than pushing on to the services. Then start at stage one. ## The fork in every Cusworth fuel drain: has it run yet? Everything after this point depends on one answer. If it has not once been started: - Just your tank has petrol in it for now. - The job is a drain and a flush, normally done where the car stands. - This is the best position to be in, and the whole reason step one counts. Motor run, even briefly? - Some petrol has left the tank by now, gone through your filter, and reached the fuel lines. - Run it farther and the petrol gets to the fuel injectors, having gone through the fuel pump first. - Mileage is what makes it a larger job: the lines flushed, a filter seen to, and at times more than that. Petrol does not lubricate. Diesel does, protecting the pump and injectors as it passes through, which is why the line falls where it does. A tank of petrol, left alone, damages nothing. Move that petrol, though, and it grinds down the very parts that move it. ## Calling about petrol in a diesel from Cusworth: what to have prepared A little planning is the difference between a van that finds you and a van that circles. - Where you have stopped. A postcode beginning DN5 8 is the ideal start. - Name the street — Cusworth Lane or wherever you have stopped — or the car park. - Or the landmark. A car park is quicker to find by what it serves, like the one at Aldi. - The make and model of the car, and the fact it's a diesel. - Which got in matters: AdBlue is a separate job from petrol, plus Cusworth has a page just for that. So say. - Roughly how much — in litres from the receipt, or by how long the nozzle was in. - Has it run? If so, say how far it went, and the way it was driven. - The owner may have to approve the work under some hire or company agreements — which is why it's quicker to settle whose motor it is before our technicians get there. Then phone 0333 366 0103. If it can wait — the car is at home and going nowhere — works as well. ## Whilst you wait for a fuel drain in Cusworth During the wait, the harm comes from well-meant help — which is why these matter. - Your safety comes before the car. Somewhere unsafe? Get away from the traffic then wait away from it. Safe where it is? Stay with it. - No one — however kind — starts it, whether to see if it runs or to move the vehicle a short way. - No additives. Two-stroke oil, injector cleaner, anything from your boot — none of that gets that petrol back out. - Clearing it yourself is not the answer: a can of siphoned petrol on a verge is a danger, and your fuel beyond that tank stays put anyway. - Leave the ignition off — the windows and your radio too. ## When the van gets there: the fuel drain, step by step - Fuel, quantity, whether it has run: the answers decide the job, and that is why we give a price after them instead of before. - Your tank is cleared. The tainted blend comes from the tank. - If it ran, your lines are carrying petrol that has moved beyond the tank — so they are cleaned. - Then the filter: swapped where there's a workable one, cleared where there is not. - Clean diesel goes in, then the fuel system is primed. - The start-up. With new diesel in and your system bled, it is fired up and tested to confirm it runs properly. Until it runs on clean diesel, our engineers stay with it. Long-term damage is very rare if it has been noticed early, so your car can go right back to normal driving. ## After the fuel drain is done: driving around Cusworth again - Drive normally. There's nothing special to do once it has been started on clean fuel. - Give the first miles your attention. Smoke showing, a warning light coming on, the idle going lumpy or the throttle hesitating: pull over then call us back. - The work may come up later with a hire company, an insurer or a fleet manager. Keep the paperwork. - Next time, trust the petrol pump's label instead of the colour of its handle. ## About Cusworth and where it is Cusworth is a village in South Yorkshire, situated near the town of Doncaster and surrounded by other local communities such as Scawsby and Richmond Hill.
